TL;DR
Both annuities and bond ladders provide predictable retirement income, but they work differently. Annuities offer mortality credits (higher payouts by pooling longevity risk) and lifetime guarantees. Bond ladders preserve principal and offer flexibility but typically yield less. The calculator helps compare after-tax income and longevity protection.
How they differ
Annuity Advantages
- Lifetime income regardless of how long you live
- Mortality credits can boost payouts 20-40% above bond yields
- No ongoing management required
- Protection from market volatility and sequence-of-returns risk
Bond Ladder Advantages
- Principal remains your own (passes to heirs)
- Liquidity if you need to access principal early
- Transparency—know exactly what you own
- Potential for capital gains if interest rates fall
Key Trade-off Annuities: Irrevocable decision, limited liquidity, higher lifetime income Bond ladders: Flexible access, inheritance value, lower guaranteed income
Income comparison framework
For a $100,000 investment at age 65:
| Strategy | Approximate Monthly Income | Longevity Protection |
|---|---|---|
| Single premium immediate annuity | $550-$650 | Lifetime |
| 10-year Treasury ladder | $380-$420 | 10 years only |
| 20-year corporate bond ladder | $450-$500 | 20 years only |
| High-yield bond ladder | $550-$600 | Maturity dates vary |
Actual yields vary with interest rates and credit quality.
When to choose each
Annuities are better if:
- You expect to outlive your actuarial寿命 expectancy
- You want maximum guaranteed lifetime income
- You’re comfortable giving up liquidity and principal for higher payouts
- You have sufficient liquid assets outside this strategy
Bond ladders are better if:
- Estate preservation is a priority
- You may need lump-sum access to principal
- You have shorter time horizons or health concerns
- You want to maintain control over your assets
Hybrid approaches
Many retirees split assets between both strategies: enough annuity income to cover essential expenses, with a bond ladder for discretionary spending and liquidity needs. This creates guaranteed income floor while preserving flexibility.

FAQ
Can I ladder annuities like bonds?
Yes, by purchasing annuities at different ages or with different start dates. This can hedge interest rate risk and provide inflation protection through higher payouts later in life.
What happens to my bond ladder if I live past the maturity dates?
You would need to reinvest at prevailing rates. Annuities guarantee income for life regardless of market conditions.
Which has better inflation protection?
Neither is ideal. Bond ladders can incorporate TIPS for direct inflation protection. Annuities require COLA riders which significantly reduce initial payouts.
