Mortgage Points Explained

Mortgage points are upfront fees paid at closing that reduce your interest rate (discount points) or cover origination costs (origination points). Buying points involves an immediate cash outlay to lower your monthly payment; whether it’s worth it depends on how long you keep the loan.

Two Types of Points

Discount points are optional fees you pay upfront to permanently reduce your interest rate. Each point typically costs 1% of the loan amount. On a $300,000 mortgage, one point costs $3,000. In return, the lender reduces your rate by roughly 0.25–0.50 percentage points. If the going rate is 6%, buying one point might drop it to 5.75% or 5.50%.

Origination points are fees the lender charges to cover the cost of underwriting, processing, and closing your loan. A lender might charge 0.5–1.5 origination points as part of their standard fee structure. Unlike discount points, you don’t buy origination points—the lender assesses them. They may be rolled into your interest rate, quoted as an upfront fee, or negotiated as part of the overall loan terms.

This article focuses on discount points, since origination points are largely non-negotiable and vary by lender.

How Buying Points Lowers Your Rate

Lenders offer a rate sheet with the base rate and a schedule showing how much each additional point reduces that rate. On a given day, the base rate might be 6.00%. The lender’s schedule might show:

You choose how many points to buy. More points mean lower rates, but you pay cash at closing. This is a trade: spend money now to save money on monthly payments later.

The Break-Even Calculation

The critical question: at what point do your cumulative interest savings exceed what you paid for the points?

Suppose you borrow $300,000 at 6% for 30 years (no points). Your monthly payment is roughly $1,799.

Now suppose you buy one point ($3,000) to lower the rate to 5.75%. Your new monthly payment is roughly $1,751. That’s a $48 monthly savings.

Break-even is the point at which your cumulative monthly savings ($48 × number of months) equals the upfront cost ($3,000):

$3,000 ÷ $48 ≈ 63 months, or about 5.25 years.

If you keep the loan for more than 5.25 years, you come out ahead. If you sell or refinance within 5.25 years, you lose money on the points because your cumulative savings haven’t yet covered the upfront cost.

Break-even typically ranges from 3 to 7 years, depending on:

• How many points you buy
• The rate reduction per point
• The loan amount and term
• Current interest rate levels

In a low-rate environment (3–4%), each additional point might save only 0.20%, making break-even longer. In a high-rate environment (6–7%), each point might save 0.50%, shortening break-even.

The Trade-Off: Cash Now vs. Savings Later

Buying points forces a choice. You have two paths:

Path A: Pay no points, keep your cash, accept the higher monthly payment. Path B: Pay upfront, lower your monthly payment, but require a longer hold to break even.

The right choice depends on your situation. If you have ample cash reserves and plan to stay in the property for 7+ years, points often make sense. If you have limited liquidity or expect to sell or refinance within 5 years, points are usually a poor trade.

Recent homebuyers in a rising-rate market have sometimes taken the opposite tack: accept a higher rate to reduce upfront cash required at closing. Lenders can roll points into the rate, meaning you pay no upfront fee but accept 0.50–0.75% higher interest. This defers the cost to your monthly payment. Whether it’s a good deal depends again on how long you hold.

Example: Two-Point Purchase

Buying two points costs $6,000 and might drop your 6% rate to 5.50%.

The monthly savings are $96. To recoup $6,000, you need 62.5 months of savings—just over 5 years. But compounding mortgage amortization means the early months include more interest and less principal paydown. The true break-even is closer to 7 years for two points in this scenario.

Tax Deductibility of Discount Points

In the United States, discount points on a primary residence mortgage may be tax-deductible as mortgage interest in the year you buy them, subject to IRS rules. You cannot deduct origination points. Consult a tax advisor, as rules vary by whether you’re a first-time buyer and other factors.

Points on investment properties or second homes have different treatment. Points may be deducted over the life of the loan rather than immediately.

When Discount Points Don’t Make Sense

Short holding periods: If you plan to sell within 3–5 years, the math almost never favors buying points. Your cumulative savings won’t cover the upfront cost.

Refinancing likelihood: If you think you’ll refinance before break-even, points are wasted. You lose the benefit of the lower rate when you refinance into a new loan.

Tight cash flow: If you’re scraping together a down payment and closing costs, paying extra for points strains your emergency reserves. The monthly savings may not justify the risk.

Floating-rate or adjustable loans: If your loan rate is adjustable, discount points bought to lower the initial rate provide less long-term value, since the rate will reset anyway.

Lender Incentives and Rate Sheets

Lenders profit when you buy discount points, because you’ve locked in a lower rate that generates less interest income to them over time. Some lenders are more generous with point discounts than others. It’s worth shopping among lenders not just for the base rate, but for their points schedule. A lender offering 0.50% off per point is better than one offering 0.25% per point, all else equal.

Some lenders also price discounts into the rate itself rather than offering explicit points. They quote you a “par rate” (no points required) and higher rates if you want to roll costs into the mortgage. This is equivalent to negative points—you pay interest over time instead of cash upfront.

The Bottom Line

Discount points are a legitimate lever for reducing long-term borrowing costs, but only if you stay in the loan long enough. The break-even horizon is typically 5–7 years; if your timeline is shorter, skip the points and keep your cash. If you’re confident you’ll be in the property for a decade or more, calculating the precise break-even and comparing it to your plans makes sense. Points are neither inherently good nor bad—they’re a timing decision.
