3-5-7-10 Year Ladder
3-5-7-10 Year Ladder
The 3-5-7-10 ladder is one of the simplest and most practical templates for individual investors: four rungs at staggered intervals, offering a middle ground between too-frequent and too-sparse reinvestment timing.
Key takeaways
- A four-rung ladder (3, 5, 7, 10 years) requires reinvestment roughly every 2–3 years, striking a balance between active management and simplicity.
- This template yields more than a short ladder (say, 1-3-5 years) but with less complexity than a ten-rung ladder.
- Equal allocations (25% per rung) are the default, but tilting slightly (30-25-22-23%) toward longer maturities can capture a yield premium.
- The 3-5-7-10 ladder is ideal for portfolios of 50,000 to 500,000 dollars in bonds; below 50,000, fewer rungs are practical.
- Works equally well with individual bonds, bond funds, or a hybrid approach.
Why four rungs?
A two-rung ladder (short and long, like 2 and 10 years) is a barbell, not a ladder. A ten-rung ladder (one per year, 1–10) is granular but requires more maintenance.
Four rungs hit a sweet spot:
- Yield: More yield than a 1-3-5 ladder (because you have positions at 7 and 10 years).
- Frequency: Reinvestment every 2–3 years (year 3, 5, 7, 10) is manageable; not overwhelming.
- Simplicity: You can track four positions in your head or in a one-page spreadsheet.
- Diversification: You have positions across the yield curve, so you are not overweighting short-term risk or long-term duration risk.
The basic 3-5-7-10 allocation
For a 100,000 dollar bond allocation:
| Maturity | Allocation | Example |
|---|---|---|
| 3 years | 25,000 | IEF, or individual 3y Treasury |
| 5 years | 25,000 | BND, or individual 5y corporate |
| 7 years | 25,000 | TLT-subset, or individual 7y municipal |
| 10 years | 25,000 | VBTLX, or individual 10y Treasury |
For a 50,000 dollar allocation:
| Maturity | Allocation | Example |
|---|---|---|
| 3 years | 12,500 | SHV or short Treasury ETF |
| 5 years | 12,500 | Core bond ETF |
| 7 years | 12,500 | Intermediate bond fund |
| 10 years | 12,500 | Long-intermediate fund |
Even with only 12,500 dollars per rung, if you are using ETFs, you can own shares fractionally or as full shares without issue.
Reinvestment events in a 3-5-7-10 ladder
Year 0: You build the ladder.
Year 3: Your 3-year rung matures. You receive 25,000 dollars principal (plus coupons). Reinvest into a new 10-year bond. Now your ladder spans 2–10 years (the old 5-year is now 2 years old, the old 7-year is now 4 years old, etc.).
Year 5: Your original 5-year rung matures. Reinvest into a new 10-year bond.
Year 7: Your original 7-year rung matures. Reinvest into a new 10-year bond.
Year 10: Your original 10-year rung matures. Reinvest into a new 10-year bond.
Then the cycle repeats. Between years 10 and 13, you are reinvesting the three new 10-year bonds you added in years 3, 5, and 7.
This staggering means you never have idle capital: something is always maturing, and you are always putting money to work at the long end.
Choosing specific bonds and funds for each rung
The 3-5-7-10 template is flexible. You can populate it with different instrument types:
All Treasury bonds (safest, lowest yield):
- 3y: Individual 3-year Treasury, or Treasury ETF (VGIT, IEF subset).
- 5y: Individual 5-year Treasury, or Treasury ETF (IEF).
- 7y: Individual 7-year Treasury (or pair of 5y and 10y).
- 10y: Individual 10-year Treasury, or Treasury ETF (IEF, TLT).
Example cost: 0–0.03% expense ratio for Treasury ETFs.
Core bond blend (moderate yield, diversified):
- 3y: Short-intermediate corporate bond fund (VCIT, VCSH, LQD subset).
- 5y: Total bond market fund (BND, VBTLX).
- 7y: Intermediate bond fund (VBIT).
- 10y: Long-term bond fund (VBTLX, BND).
Example cost: 0.03–0.10% expense ratio.
Tax-advantaged municipals (if in high tax bracket):
- 3y: Short municipal ETF (MUB subset, individual short municipal bonds).
- 5y: Intermediate municipal ETF (MUB).
- 7y: Individual 7-year municipal bonds (research issuer credit quality).
- 10y: Long municipal ETF (MUB, VMLX) or individual 10-year municipals.
Example tax benefit: If you are in the 32% federal tax bracket and muni bonds yield 3.5%, your after-tax yield is roughly 5.2% (3.5% / (1 - 0.32)).
Hybrid approach (balance and simplicity):
- 3y: Treasury or short corporate ETF (0.04% expense).
- 5y: Total bond ETF (0.04% expense).
- 7y: Individual intermediate corporate bond (no ongoing expense, one-time bid-ask spread).
- 10y: Long bond ETF (0.04% expense).
This hybrid reduces your ongoing cost while keeping individual bonds manageable (one or two positions instead of four).
Tilting the allocation for yield
If you are willing to accept slightly more interest-rate risk, you can tilt the allocation toward the longer maturities:
Standard equal tilt:
- 3y: 25%
- 5y: 25%
- 7y: 25%
- 10y: 25%
Yield-tilted allocation:
- 3y: 20% (less, because yield is lower)
- 5y: 25%
- 7y: 27% (more)
- 10y: 28% (most)
The yield curve typically slopes upward (longer bonds pay more), so tilting toward the long end increases your expected yield. In 2023–2024, with 10-year Treasuries yielding 4–4.5% and 3-year Treasuries yielding 4.5–5.2%, the curve was inverted, making the tilt less relevant.
The key is knowing the shape of the curve at the time you build your ladder. If the curve is steep (long yields much higher), tilt long. If it is flat or inverted, keep allocations equal.
Maintenance checklist
Every quarter:
- Verify that no maturity is coming due in the next 6 months (set calendar reminders).
- Check the combined value of the four rungs; if one has drifted more than 15% from target (e.g., 3-year rung is now 30k instead of 25k), consider rebalancing.
Every year:
- Review the credit quality of any individual bonds you hold. Have any been downgraded? If so, decide whether to hold or sell.
- Track coupon income and decide whether to spend or reinvest.
- Rebalance if allocations are significantly off (more than 10% drift per rung).
When a rung matures:
- Execute the reinvestment into a new 10-year position within 1–2 days (do not let cash sit idle).
- Update your tracking spreadsheet.
- Verify the maturity date of the new bond or fund duration.
Scaling the ladder
The 3-5-7-10 template works at many scales:
Small ladder (25,000 dollars total):
- 3y: 6,250 (5 shares of a Treasury ETF).
- 5y: 6,250.
- 7y: 6,250.
- 10y: 6,250.
Practical minimum: If using individual bonds (which often have 5,000 dollar minimums), you need at least 20,000 dollars to keep allocations reasonable. Below that, use bond ETFs exclusively.
Large ladder (500,000 dollars total):
- 3y: 125,000.
- 5y: 125,000.
- 7y: 125,000.
- 10y: 125,000.
With 125,000 per rung, you can own 2–3 individual bonds per rung for diversification, or a single large ETF position, or a hybrid. The key is still discipline: reinvest maturing rungs into the long end.
Real-world example: building your first 3-5-7-10 ladder
Suppose you have 80,000 dollars to invest in bonds and want to use the 3-5-7-10 template.
Month 1: Build the ladder
- 3-year: 20,000 into SHV (short Treasury ETF) at 100 dollars per share = 200 shares.
- 5-year: 20,000 into BND (total bond market) at 80 dollars per share = 250 shares.
- 7-year: 20,000 into a 7-year Treasury ETF (VGIT) at 75 dollars per share = 267 shares.
- 10-year: 20,000 into TLT (long Treasury ETF) at 95 dollars per share = 211 shares.
Total cost: approximately 80,000 dollars plus bid-ask spreads (roughly 40 dollars in transaction cost).
Your ladder is now active. Every quarter, check that no position has grown or shrunk by more than 15%. Annually, decide on reinvestment of coupons.
Month 36 (Year 3): First maturity event
- SHV holdings have paid out coupons (roughly 600–800 dollars total). The shares mature or are replaced by the fund (SHVs are rotating, not fixed-maturity funds, so "maturity" here means you withdraw the principal).
- Withdraw the 20,000 dollars of principal.
- Buy a new 10-year bond. Options: 20,000 more of TLT, or 20,000 into individual 10-year Treasuries, or 20,000 into a 10-year corporate bond fund.
- Your ladder now effectively spans 2–10 years (the old 5-year is now 2 years old, etc.).
- Reset your tracking spreadsheet.
Repeat this process at months 60, 84, and 120.
Comparing 3-5-7-10 to other templates
| Template | Reinvestment Frequency | Yield | Complexity | Best For |
|---|---|---|---|---|
| 1-3-5 | Every 1–2 years | Low | Low | Conservative, short-horizon investors |
| 3-5-7-10 | Every 2–3 years | Medium | Medium | Most individual investors |
| 2-4-6-8-10 | Every 2 years | Medium | Medium | Disciplined, methodical planners |
| 1-2-3...10 | Every year | Medium | High | Very active investors, large portfolios |
The 3-5-7-10 template is the "Goldilocks" choice for most people: not too simple, not too complex, reinvestment frequently enough to capture rate cycles, but not so often that you are constantly redeploying.
