Glossary
This glossary defines the key terms and acronyms you'll encounter throughout Personal Finance Foundations. Each entry provides a concise definition followed by practical context and real-world examples to help you understand how these concepts apply to your financial life. Whether you're building a budget, comparing credit cards, or evaluating insurance options, these definitions will clarify the language you need to manage your money effectively.
401(k)
A retirement savings plan sponsored by an employer that allows workers to contribute a portion of their pre-tax wages.
When you enroll in a 401(k), contributions are deducted from your paycheck before income tax is calculated, reducing your taxable income for the year. For example, if your employer offers a 401(k) with a 3% match and you earn $60,000 annually, contributing $1,800 (3%) triggers an employer match of $1,800. Many plans offer investment options, allowing you to choose how your contributions grow, and withdrawals before age 59½ typically incur a 10% penalty plus taxes.
529 Plan
A tax-advantaged savings account designed specifically for qualified education expenses such as tuition, fees, and room and board.
Money contributed to a 529 plan grows tax-free as long as withdrawals are used for eligible education costs at any accredited college or university. If you contribute $10,000 per year to your child's 529 plan for 10 years and the account grows to $150,000, that entire $50,000 gain is tax-free when used for college. Recent rules allow up to $35,000 to be rolled into a Roth IRA if the account has been open for 15 years or more.

ACA (Affordable Care Act)
Federal legislation enacted in 2010 that expanded health insurance coverage and reformed the health insurance market.
The ACA established protections such as coverage for people with pre-existing conditions, preventive care without cost-sharing, and subsidies for low-to-moderate income households. If you earn $50,000 and apply for coverage through the ACA Marketplace, you may qualify for tax credits that reduce your monthly premium from $400 to $150, making insurance affordable.

APR (Annual Percentage Rate)
The yearly cost of borrowing money, expressed as a percentage, including interest and fees.
APR differs from interest rate because it accounts for both the interest charge and any origination fees, closing costs, or other borrowing costs. If a credit card advertises 0% APR for 12 months on balance transfers, a $5,000 transfer costs nothing during that period; after 12 months, the standard APR (say, 18%) applies to any remaining balance.
See also: APY, Balance transfer.
APY (Annual Percentage Yield)
The yearly return on an investment or savings account, accounting for compound interest.
APY is higher than the stated interest rate because it reflects how often interest compounds. A high-yield savings account offering 4.5% APY on a $10,000 deposit earns approximately $450 in the first year, with interest earned on both the principal and previously earned interest if compounding occurs monthly.
ARM (Adjustable-Rate Mortgage)
A mortgage loan with an interest rate that changes periodically, typically lower initially than fixed-rate mortgages.
An ARM often starts with a low "teaser" rate, then adjusts annually or semi-annually based on a market index plus a lender margin. A 5/1 ARM with a 3% initial rate and 2% margin might have a starting monthly payment of $1,432 on a $400,000 loan; after five years, the rate adjusts to roughly 5% (if the index is 3%), raising the payment to $1,800 or more.
See also: Fixed expense, Mortgage points.
Auto Insurance
Coverage that protects against financial loss from accidents, theft, or liability involving a vehicle.
Auto insurance typically includes liability (covering damages to others), collision (covering damage to your car), comprehensive (covering theft or weather damage), and uninsured/underinsured motorist coverage. If you cause an accident that results in $50,000 of damages to another car, your liability coverage (say, $100,000) pays the other driver's claim.
See also: Deductible, Premium.
Avalanche Method
A debt-repayment strategy that prioritizes paying off high-interest debt first while making minimum payments on other debts.
The Avalanche Method saves the most money on interest over time. If you owe $500 on a credit card at 20% APR and $5,000 on a personal loan at 8% APR, paying extra toward the credit card first eliminates the higher-cost debt faster, reducing total interest paid.
See also: Debt consolidation, Snowball method.
Balance Transfer
Moving an outstanding debt from one creditor to another, often to a card with a lower interest rate or promotional offer.
A balance transfer can reduce interest costs significantly, but typically incurs a fee (1–3% of the transferred amount). If you transfer a $10,000 balance from a 20% APR card to a card offering 0% APR for 12 months with a 2% transfer fee, you pay $200 upfront but save approximately $1,200 in interest if you clear the balance within the promotional period.
See also: APR, Credit utilization.
Beneficiary
A person or entity designated to receive benefits from a financial account, insurance policy, or estate upon the account holder's death.
Naming a beneficiary on a 401(k), life insurance policy, or bank account allows those assets to pass directly to the designated person outside of probate. If you name your spouse as beneficiary of a $500,000 life insurance policy, your spouse receives the full $500,000 tax-free when you pass away.
See also: Estate plan, Life insurance.
Budget
A detailed plan that tracks income and allocates it to expenses, savings, and debt repayment.
A budget creates intentionality around spending and helps identify where money is going. If you earn $4,000 monthly after taxes, a typical budget might allocate 30% ($1,200) to housing, 15% ($600) to food, 10% ($400) to transportation, 5% ($200) to insurance, 10% ($400) to debt repayment, and 30% ($1,200) to savings and discretionary spending.
See also: Envelope budgeting, Zero-based budget.
CD Ladder
An investment strategy that spreads money across certificates of deposit (CDs) with staggered maturity dates.
A CD ladder provides both liquidity and higher yields than a regular savings account. You might invest $10,000 in five one-year CDs of $2,000 each; as each CD matures annually, you reinvest the principal plus interest in a new one-year CD, ensuring access to a portion of your money every 12 months.
See also: Emergency fund, Money market.
Closing Costs
Fees and expenses incurred when finalizing a real estate transaction, typically 2–5% of the loan amount.
Closing costs include appraisal fees, title insurance, attorney fees, property taxes, and lender origination fees. On a $400,000 home purchase with a $320,000 mortgage at 3% closing costs, you'd pay approximately $9,600 in closing costs at closing, in addition to your down payment.
See also: Down payment, Mortgage points.
COBRA (Consolidated Omnibus Budget Reconciliation Act)
Federal legislation allowing employees to continue employer-sponsored health insurance for a limited time after job loss, typically 18 months.
COBRA coverage is often expensive because you pay the full premium (previously split with your employer) plus a 2% administrative fee. If your employer paid $400 monthly for your health insurance, COBRA coverage might cost you $600–$700 monthly, but it provides continuity until you find new employment or individual coverage.
See also: ACA, Health insurance.
Credit Bureau
A company that collects, maintains, and reports credit history and financial information on borrowers.
The three major credit bureaus—Equifax, Experian, and TransUnion—compile payment history, outstanding debts, and other financial data to create credit reports and scores. Lenders use these reports to assess creditworthiness and set interest rates; if you've paid all bills on time for two years, your credit bureau file reflects this positive history, which may qualify you for a lower interest rate on a mortgage.
See also: Credit freeze, Credit utilization, FICO.
Credit Freeze
A security measure that restricts access to your credit report, preventing unauthorized accounts from being opened in your name.
A credit freeze is free and does not affect your credit score, but you must lift it (unfreeze) when you want to apply for new credit. If you experience identity theft or worry about data breaches, placing a freeze with all three credit bureaus prevents fraudsters from opening credit cards or loans in your name.
See also: Credit bureau, Identity theft.
Credit Utilization
The percentage of available credit you are currently using, calculated as outstanding balance divided by total credit limit.
Lenders view low credit utilization (below 10%) as a sign of responsible credit management. If you have three credit cards with $5,000 limits each ($15,000 total) and $3,000 in balances, your utilization is 20%; paying down balances to $1,500 improves your utilization to 10% and may raise your credit score.
See also: Balance transfer, FICO, Secured card.
Debt Consolidation
Combining multiple debts into a single loan, typically to lower the interest rate or simplify repayment.
Debt consolidation can reduce monthly payments and interest costs if the new loan has a lower rate. If you consolidate three debts—a $5,000 credit card at 18% APR, a $3,000 personal loan at 12% APR, and a $2,000 store card at 24% APR—into a single loan at 10% APR, your total interest cost drops significantly.
See also: Avalanche method, Snowball method.
Deductible
The amount you must pay out-of-pocket before insurance coverage begins.
A higher deductible lowers your insurance premium but increases what you pay when a loss occurs. If your auto insurance has a $1,000 deductible and you have a $4,000 accident, you pay $1,000 and the insurance company pays $3,000.
See also: Auto insurance, Premium.
Disability Insurance
Insurance that replaces a portion of income if you become unable to work due to illness or injury.
Disability insurance protects your financial security if you cannot earn income. If you have a long-term disability policy that replaces 60% of your $80,000 salary and you suffer an injury that prevents work for two years, the policy pays you $4,000 monthly (60% of $6,667), replacing most of your lost income.
See also: Emergency fund, Health insurance.
Down Payment
The initial cash payment made at the purchase of real estate or vehicle, reducing the amount that must be borrowed.
A larger down payment lowers your loan amount and monthly payment. On a $300,000 home purchase, a 20% down payment ($60,000) means financing $240,000; a 10% down payment ($30,000) means financing $270,000, resulting in a higher monthly mortgage payment.
See also: Closing costs, PMI.
Emergency Fund
Savings set aside to cover unexpected expenses or income loss, typically 3–6 months of living expenses.
An emergency fund prevents reliance on debt when unexpected costs arise. If your monthly expenses are $4,000, an emergency fund of $12,000–$24,000 covers a job loss, medical emergency, or major home repair without derailing your financial plan.
See also: CD ladder, HYSA, Savings rate.
Envelope Budgeting
A budgeting method that allocates cash to physical envelopes or digital accounts for specific spending categories.
Envelope budgeting makes spending limits tangible and prevents overspending. You might divide your monthly $2,000 discretionary budget into four $500 envelopes: groceries, dining out, entertainment, and personal care; when an envelope is empty, you stop spending in that category.
See also: Budget, Fixed expense.
Estate Plan
A legal document that specifies how your assets and affairs should be managed if you become incapacitated or die.
An estate plan typically includes a will, power of attorney, healthcare proxy, and beneficiary designations. Without an estate plan, your state's intestacy laws determine how your assets are distributed, which may not reflect your wishes; with one, you ensure your children's guardianship, your spouse's financial security, and your charitable goals are honored.
See also: Beneficiary, Letter of instruction, Probate.
FAFSA (Free Application for Federal Student Aid)
The federal form through which students apply for federal and institutional financial aid for college.
The FAFSA determines your Expected Family Contribution (EFC) and eligibility for grants, loans, and work-study. If you file the FAFSA and your family's EFC is $5,000, you may qualify for a $10,000 federal Pell Grant at a public university with a $15,000 total cost of attendance.
See also: 529 Plan.
FDIC (Federal Deposit Insurance Corporation)
A U.S. government agency that insures deposits in member banks up to $250,000 per account holder per institution.
FDIC insurance protects your deposits if a bank fails. If you keep $250,000 in a checking account at a FDIC-insured bank and the bank becomes insolvent, the FDIC reimburses your full balance, protecting your funds from loss.
See also: HYSA, Money market.
FICO (Fair, Isaac and Company)
The company that creates the most widely used credit score, ranging from 300 to 850.
FICO scores are calculated based on payment history (35%), amounts owed (30%), length of credit history (15%), credit mix (10%), and new credit (10%). A FICO score above 750 typically qualifies you for prime interest rates on mortgages and auto loans; below 600 limits credit options and results in higher rates.
See also: Credit bureau, VantageScore.
Fixed Expense
A recurring cost that remains the same amount each month, such as rent or mortgage payments.
Fixed expenses make budgeting predictable because you know exactly what to allocate. Your rent of $1,500 monthly, car payment of $350, and insurance of $150 are fixed expenses totaling $2,000; variable expenses like groceries and utilities fluctuate.
See also: Budget, Variable expense.
FSA (Flexible Spending Account)
A tax-advantaged account allowing employees to set aside pre-tax money for qualified medical and dependent care expenses.
Money contributed to an FSA reduces your taxable income and grows tax-free if used for eligible expenses. If you contribute $3,000 annually to an FSA for medical expenses, you reduce your taxable income by $3,000 and use the account to pay for deductibles, co-pays, and prescriptions tax-free.
Gift Tax
A federal tax on money or property transferred to another person during the giver's lifetime.
The annual gift tax exclusion allows you to give up to $18,000 per recipient per year (as of 2024) without filing a gift tax return or using your lifetime exemption. If you have three adult children and want to help with down payments, you can give each $18,000 ($54,000 total) without triggering a gift tax.
See also: Estate plan.
HSA (Health Savings Account)
A tax-advantaged account available to people with high-deductible health insurance, used to save for qualified medical expenses.
An HSA offers triple tax benefits: contributions are tax-deductible, growth is tax-free, and withdrawals for qualified medical expenses are tax-free. If you contribute $4,150 annually to an HSA and invest it, earning $500 in gains and spending $2,000 on medical expenses, all $6,650 in contributions and earnings avoid taxes.
HYSA (High-Yield Savings Account)
A savings account offered by banks or online-only institutions that pays interest rates significantly higher than traditional savings accounts.
A HYSA offers rates of 4–5% APY, compared to 0.01% at a traditional savings account. A $10,000 emergency fund in a HYSA earning 4.5% APY grows to $10,450 in one year; in a traditional savings account at 0.01%, it grows to only $10,001.
See also: APY, CD ladder, FDIC.
Healthcare Proxy
A legal document designating someone to make medical decisions on your behalf if you become unable to do so.
A healthcare proxy ensures your medical preferences are honored if you're incapacitated. If you're in a serious accident and cannot communicate, your healthcare proxy (perhaps your spouse) can authorize surgery, decline treatment, or make end-of-life decisions based on your known wishes.
See also: Estate plan, POA.
HDHP (High-Deductible Health Plan)
A health insurance plan with lower premiums but higher deductibles, often paired with an HSA.
An HDHP might have a $3,000 individual deductible and $5,000 family deductible, with lower monthly premiums than a traditional plan. If you're healthy and rarely need medical care, an HDHP paired with an HSA lets you save money on premiums and set aside pre-tax dollars for future healthcare expenses.
See also: ACA, Deductible, HSA.
Letter of Instruction
A non-binding document that provides guidance to your executor or heirs about your wishes, such as where to find important documents or funeral preferences.
A letter of instruction complements your will by providing practical information. You might document where your will is stored, which accounts and investments you hold, funeral or burial preferences, digital asset locations, and contact information for your financial advisors, making it easier for your executor to manage your estate.
See also: Estate plan, Probate.
Life Insurance
Insurance that pays a death benefit to beneficiaries when the insured person dies.
Life insurance provides financial security for dependents or creditors. A 35-year-old with two children and a $300,000 mortgage might purchase a 30-year term life insurance policy with a $1 million death benefit for $30 monthly; if he dies, his family receives $1 million tax-free to pay off the mortgage, cover living expenses, and fund education.
See also: Beneficiary, Term life, Umbrella insurance.
LLC (Limited Liability Company)
A business structure that provides liability protection to its owners (members) while allowing flexible taxation and management.
An LLC protects your personal assets if the business faces a lawsuit. If you operate a consulting LLC with a gross value of $500,000 and a client sues for $200,000, the lawsuit typically targets the LLC's assets, not your personal home or bank accounts.
See also: Solo 401(k).
Marketplace Plan
A health insurance plan purchased through the ACA Health Insurance Marketplace, often with government subsidies for low-income individuals and families.
The Marketplace allows you to compare plans from multiple insurers and apply for subsidies that reduce your premiums. If you earn $50,000 annually and enroll in a Silver plan through the Marketplace, you might pay $100 monthly after subsidies instead of $400, making coverage affordable.
Money Market
A short-term investment fund that holds low-risk securities such as Treasury bills, CDs, and commercial paper.
A money market fund offers modest returns with minimal risk. A money market fund might yield 4.5% APY while a savings account yields 4%, making the fund attractive for emergency reserves where safety and liquidity matter more than growth.
See also: CD ladder, Emergency fund.
Mortgage Points
Fees paid to a lender at closing to reduce the interest rate on a mortgage, with each point equal to 1% of the loan amount.
Mortgage points are a trade-off between upfront costs and long-term savings. On a $400,000 mortgage at 6% APR, paying two points ($8,000) might reduce the rate to 5.5% APR, lowering your monthly payment by $150; you break even on the $8,000 investment after 53 months.
See also: Closing costs, Down payment.
NCUA (National Credit Union Administration)
A U.S. government agency that insures deposits in member credit unions up to $250,000 per account holder.
NCUA insurance works similarly to FDIC insurance but covers credit unions instead of banks. If you keep $250,000 in a share draft account at an NCUA-insured credit union and the institution fails, NCUA reimburses your full balance.
See also: FDIC.
Overdraft
When you withdraw more money from an account than you have available, resulting in a negative balance.
Banks may either decline the transaction or honor it and charge an overdraft fee (typically $30–$40 per occurrence). If you have $500 in your checking account and attempt to withdraw $600, the bank may decline the transaction or pay it and charge you a $35 overdraft fee, leaving you with a –$100 balance.
See also: Budget.
Pay-Yourself-First
A savings strategy where you automatically transfer a portion of income to savings before paying bills or discretionary expenses.
By paying yourself first, you prioritize savings and make it automatic. If you earn $4,000 monthly and transfer $400 to savings before paying any bills, you guarantee $4,800 in annual savings; most people who wait to save what remains after expenses never save enough.
See also: Emergency fund, Savings rate.
PMI (Private Mortgage Insurance)
Insurance required when a down payment is less than 20%, protecting the lender if you default on the loan.
PMI is typically rolled into your monthly mortgage payment and adds 0.3–1% to the loan amount annually. On a $400,000 home with a 10% down payment ($40,000), you finance $360,000 and pay PMI of roughly $900–$3,600 annually until your equity reaches 20%.
See also: Down payment, Mortgage points.
POA (Power of Attorney)
A legal document authorizing someone (an agent) to act on your behalf for financial or legal matters.
A power of attorney can be limited (for a specific transaction) or durable (effective immediately or when you become incapacitated). If you create a durable financial POA naming your spouse, she can access your accounts, pay bills, and manage investments if you become seriously ill.
See also: Estate plan, Healthcare proxy.
Premium
The regular payment made to an insurance company to maintain coverage.
Insurance premiums are paid monthly, quarterly, or annually depending on the policy. A 35-year-old non-smoker in good health might pay $35–$50 monthly for term life insurance; a smoker or someone with health conditions would pay significantly more for the same coverage.
See also: Deductible, Disability insurance.
Probate
The legal process of validating a will and distributing an estate's assets to heirs.
Probate can take months or years and incur legal fees, court costs, and executor fees that reduce the estate's net value. Assets outside probate (like life insurance with named beneficiaries or joint accounts) pass directly to the designated person, avoiding delays and fees.
See also: Beneficiary, Estate plan.
Renters Insurance
Insurance that covers a tenant's personal belongings and provides liability protection for injuries on the rental property.
Renters insurance is affordable (often $15–$25 monthly) and essential. If your apartment is burglarized and $5,000 in electronics, clothing, and furniture is stolen, renters insurance reimburses you; without it, you absorb the full loss.
See also: Deductible, Umbrella insurance.
Revocable Trust
A legal arrangement that holds your assets during your lifetime and specifies how they pass to beneficiaries after your death, and can be changed or terminated during your life.
A revocable trust allows you to avoid probate and maintain control of your assets. If you place your home, investments, and bank accounts in a revocable trust, they pass to your beneficiaries (perhaps your children) without probate delays or public court proceedings.
See also: Estate plan, Probate, Trust.
Roth IRA
An individual retirement account where contributions are made with after-tax dollars, but qualified withdrawals in retirement are tax-free.
A Roth IRA offers unique tax benefits: you pay taxes on contributions now, but all growth and withdrawals are tax-free after age 59½. If you contribute $7,000 annually for 30 years and the account grows to $500,000, you withdraw $500,000 in retirement tax-free.
RSU (Restricted Stock Unit)
A form of equity compensation where an employee is awarded shares of company stock that vest over a specified schedule.
RSUs provide delayed equity ownership. You might receive 400 RSUs vesting over four years (100 per year); after one year, 100 shares are yours to keep or sell at market value. If the stock price is $100, your first-year vesting is worth $10,000.
See also: Solo 401(k).
Savings Rate
The percentage of after-tax income that you save rather than spend.
A healthy savings rate is 15–20% or more of after-tax income. If you earn $5,000 monthly after taxes and spend $3,500, your savings rate is 30% ($1,500 saved), leaving you on track for long-term financial security.
See also: Emergency fund, Pay-yourself-first.
Secured Card
A credit card backed by a cash deposit held in a pledge account, used to establish or rebuild credit.
Secured cards are accessible to people with no credit history or poor credit. You might deposit $500 as collateral and receive a secured card with a $500 credit limit; after 12–18 months of on-time payments, the card issuer may convert it to an unsecured card and return your deposit.
See also: Credit utilization, FICO.
SEP IRA (Simplified Employee Pension IRA)
A retirement plan for self-employed individuals and small business owners, allowing larger annual contributions than traditional IRAs.
A SEP IRA allows you to contribute up to 20% of net self-employment income (up to $69,000 in 2024). If you're a freelancer earning $100,000, you can contribute up to $20,000 annually to your SEP IRA, reducing your taxable income significantly.
See also: 401(k), Solo 401(k).
Snowball Method
A debt-repayment strategy that prioritizes paying off the smallest debt first, building momentum as each debt is eliminated.
The Snowball Method provides psychological wins. If you owe $500 on a credit card, $2,000 on a personal loan, and $15,000 in student loans, paying off the credit card first gives you a win and momentum; then tackle the personal loan, then the student loans.
See also: Avalanche method, Debt consolidation.
Solo 401(k)
A retirement plan for self-employed individuals with no employees, offering higher contribution limits than traditional IRAs.
A Solo 401(k) allows you to contribute as both an employee and employer. If you earn $80,000 in self-employment income, you might contribute $15,000 as an employee and $12,000 as employer (20% of net income), totaling $27,000 annually to your retirement savings.
Term Life
A type of life insurance that provides coverage for a specified period (typically 10, 20, or 30 years) and expires at the end of the term.
Term life is affordable and straightforward. A 30-year-old purchasing a 30-year term life policy with a $1 million death benefit might pay $30–$40 monthly; if they die within 30 years, their beneficiaries receive $1 million; if they survive 30 years, the policy expires with no payout.
See also: Beneficiary, Life insurance.
Trust
A legal arrangement where one party (trustee) holds assets on behalf of another (beneficiary) according to the terms specified in the trust document.
A trust provides control and privacy. If you establish a trust naming your spouse as trustee and your children as beneficiaries, your assets are managed by the trustee for your children's benefit without going through probate, keeping the arrangement private.
See also: Estate plan, Revocable trust.
Umbrella Insurance
Additional liability coverage that provides protection beyond the limits of homeowners, auto, or renters insurance.
Umbrella insurance is inexpensive ($150–$300 annually) and provides significant protection. If you're sued for $500,000 and your auto insurance liability limit is $100,000, an umbrella policy of $1 million covers the remaining $400,000.
See also: Auto insurance, Renters insurance.
UTMA (Uniform Transfers to Minors Act)
A legal framework allowing adults to transfer assets to minors without establishing a trust, with a custodian managing the assets until the minor reaches adulthood.
A UTMA account simplifies gifting to minors. You might deposit $5,000 into a UTMA brokerage account for your nephew, naming yourself custodian; the account grows tax-advantaged, and at age 21 (or 18, depending on the state), your nephew receives full control.
See also: Gift tax.
Variable Expense
A recurring cost that changes month to month, such as groceries, utilities, or entertainment spending.
Variable expenses require careful tracking because they fluctuate. Your electricity bill might be $80 in spring but $150 in summer; groceries might be $400 one month and $350 the next, making monthly budgeting more challenging than with fixed expenses.
See also: Budget, Fixed expense.
VantageScore
A credit score created by the three major credit bureaus (Equifax, Experian, and TransUnion) as an alternative to FICO, ranging from 300 to 850.
VantageScore and FICO scores are calculated differently and may vary by 20–50 points. A FICO score of 750 might correspond to a VantageScore of 770; while some lenders use VantageScore, FICO remains more widely used for mortgage and auto loans.
See also: Credit bureau, FICO.
W-2
A tax form provided by employers to employees reporting annual wages, withholdings, and other compensation, required for tax filing.
A W-2 form is essential for filing your federal income tax return. If you earned $60,000 in wages and your employer withheld $12,000 in federal income tax, your W-2 documents both amounts; you use this form to file your return and potentially claim a refund.
See also: FAFSA.
Will
A legal document that specifies how your estate should be distributed after your death and names an executor to carry out your wishes.
A will ensures your assets go to the people and organizations you choose. A simple will might state that 50% of your estate goes to your spouse, 25% to your two children, and 25% to a charity you care about; without a will, your state's laws determine distribution.
See also: Beneficiary, Estate plan.
YNAB (You Need A Budget)
A budgeting software and methodology focused on assigning every dollar of income to a specific category before spending.
YNAB uses the zero-based budgeting principle. If you earn $4,000 monthly, you allocate the full $4,000: $1,200 to housing, $500 to food, $300 to transportation, $500 to savings, $200 to insurance, and $300 to discretionary—leaving zero unallocated.
See also: Envelope budgeting, Zero-based budget.
Zero-Based Budget
A budgeting method where income minus expenses equals zero, meaning every dollar is allocated to a specific category.
Zero-based budgeting ensures intentional spending with no money left unaccounted for. If you have $5,000 monthly income, you assign all $5,000: housing, food, transportation, savings, insurance, debt payment, and discretionary; nothing is left to drift into impulse purchases.
See also: Budget, Envelope budgeting, YNAB.
