Bond Ladders for Retirement Income

A bond ladder is a portfolio of individual bonds with staggered maturity dates. Each year, one bond matures; the proceeds become spending money or get reinvested. Predictable; controllable; insulated from rate movements in a way bond funds aren't.

For retirees wanting income certainty, bond ladders are a real tool.

How a ladder works

Build a ladder of, say, 10 years:

- $50K matures in 1 year

- $50K matures in 2 years

- ...

- $50K matures in 10 years

Total: $500K across 10 rungs.

Each year, one rung matures. The cash funds that year's spending (or some portion). The principal isn't subject to market price changes in the meantime — you receive face value at maturity.

For a multi-year ladder, this provides predictable income for the ladder duration.

Why ladders beat bond funds (sometimes)

Bond funds

Hold many bonds; trade them; aggregate value moves with rates. When rates rise, bond fund NAV drops; when rates fall, NAV rises.

For a retiree withdrawing periodically: market-value-driven sales lock in losses if rates rose since purchase.

Bond ladders

Hold individual bonds to maturity. The bond pays face value when it matures, regardless of intervening rate movements.

For predictable income, this matters. A 5-year ladder with $50K rungs delivers $50K in year 1, $50K in year 2, etc., regardless of rate changes.

The trade-off

Bond funds: liquid; diversified; subject to mark-to-market.

Ladders: less liquid (selling pre-maturity may incur loss); per-bond credit risk; immune to mark-to-market if held.

For retirement income, ladders make sense for a portion of the bond allocation.

What to ladder

US Treasuries

Risk-free (in nominal terms). Low yields but no credit risk. State-tax-free.

For most retirement ladders, Treasuries are the right base.

TIPS (Treasury Inflation-Protected Securities)

Inflation-adjusted. Principal grows with CPI. For real-purchasing-power preservation.

Best in tax-deferred accounts due to phantom income. See [IBondsAndTreasuries](IBondsAndTreasuries).

CDs

FDIC-insured. Often higher rates than Treasuries.

For shorter ladders (under 5 years), brokered CDs ladder well.

Corporate bonds

Higher yields; credit risk. For meaningful exposure, diversification matters (don't ladder one issuer).

Municipal bonds

Tax-free in some cases. For high-tax-bracket retirees, the tax-equivalent yield can beat Treasuries.

How to build a ladder

Choose duration

5 years? 10 years? 20 years?

Longer ladders provide more predictability; tie up money longer; expose you to inflation if not TIPS-based.

A common pattern: 5-7 year nominal Treasury ladder for the income needed in those years; supplement with TIPS or stocks for longer-term inflation protection.

Choose rungs

Annual rungs are typical. Some ladders have semi-annual or quarterly rungs for more frequent maturity.

Choose total amount

The ladder should cover essential expenses for the ladder duration, ideally combined with other guaranteed income (Social Security, pensions).

If essential expenses are $50K/year and Social Security is $25K, the ladder covers the $25K gap. A 10-year ladder of $250K provides this.

Construct it

Buy individual bonds via a broker (Fidelity, Schwab, Vanguard) or TreasuryDirect for Treasuries. The interface is dated but workable.

Some brokers have ladder construction tools that buy across many maturities at once.

Reinvestment

When a rung matures, you have choices:

Spend it

Use the cash for that year's expenses. The ladder shrinks each year.

For a "spend down" ladder, this is the plan.

Reinvest at the long end

Buy a new long-end rung. The ladder maintains its length.

For an indefinite ladder, this is the pattern.

Adjust based on rates

If rates have risen, longer-end rungs are more attractive to buy. If fallen, maybe shorter or different mix.

Specific patterns

Bridge to Social Security delay

You retire at 62; want to delay Social Security to 70 for higher benefits. A ladder covers years 62-70 of expenses. At 70, Social Security covers most; smaller portfolio remains.

Highly effective if you can afford to delay claiming.

TIPS ladder for retirement

A pure-TIPS ladder of, say, 30 years provides inflation-adjusted income for life. Each year a rung matures; the principal has grown with inflation.

This is a "do it yourself annuity" — provides similar function (inflation-protected lifetime income) without the insurance company.

For retirees who don't want annuities but want lifetime inflation-adjusted income: a TIPS ladder is a real alternative.

Short ladder for cash needs

3-5 year ladder for the "cash bucket" of retirement spending. Equity portfolio for longer-term growth.

When ladders don't fit

Small portfolio

Below ~$200K, the per-rung amounts are small; transaction costs and minimums are awkward. Bond funds are simpler.

Rates trending strongly

If you're confident rates will move in a specific direction, individual bonds and ladders constrain your flexibility. Bond funds are more flexible (and more risky).

Active management preferred

If you want to manage duration, credit, sector — bond funds give that flexibility. Ladders are passive once built.

Tax considerations

Tax-deferred accounts

For Treasury and TIPS ladders, holding in tax-deferred accounts (IRAs, 401(k)s) is fine. The phantom-income issue with TIPS is sheltered.

Taxable accounts

Treasuries are state-tax-free. For high-state-tax states, this matters.

Municipal bonds for high federal-tax brackets in taxable accounts.

TIPS in taxable accounts have phantom-income issues; manage carefully.

Common failure patterns

- **Ladder too short for retirement timeline**: runs out before life does

- **Ignoring inflation with nominal-only ladder**: real value erodes

- **Concentration in single corporate issuer**: credit risk from default

- **Buying individual bonds inefficiently**: bond funds may be cheaper net of transaction costs for small portfolios

- **Over-allocating to ladder**: misses equity returns over decades

A reasonable approach

For typical retirees:

1. Cover essential expenses with guaranteed income (Social Security + pensions)

2. Bond ladder fills the gap for next 5-10 years

3. Equity portfolio for inflation hedge and discretionary spending

4. Consider TIPS ladder for longer-term inflation-protected income

The ladder is one tool in the income toolkit, not the whole solution.
