Annuities vs. Systematic Withdrawals

Two approaches to converting a retirement portfolio into income: buy an annuity (insurance company guarantees lifetime income) or systematically withdraw from a managed portfolio. Both have real cases; both have real costs. Most retirees do better with one, the other, or a deliberate mix.

This page covers the trade-offs.

The annuity approach

Hand a lump sum to an insurance company; receive monthly payments for life (or a defined period). The insurer manages the investments and longevity risk; you get predictable income.

What it gives you

What it costs

The systematic-withdrawal approach

Keep the portfolio invested; withdraw a percentage annually (or as needed). The 4% rule is the canonical version.

See SafeWithdrawalRates for the full mechanics.

When annuities make sense

Need predictable income above Social Security and pensions

If your guaranteed income (Social Security, pensions) covers basic expenses, you may not need annuities. If it doesn't, annuitizing a portion to fill the gap reduces stress.

Strong fear of running out

Even if math suggests systematic withdrawal is better, sleep matters. An annuity for your "floor" of essential expenses can be worth the cost.

No heirs you want to leave money to

The annuity's main downside (no remainder for heirs) becomes a non-issue.

Late retirement

Older retirees have shorter expected lifespans; annuities are cheaper relative to expected payout. Mortality credits work in your favor.

High behavioral risk

If you've made bad investment decisions during downturns, an annuity removes that risk.

When systematic withdrawal makes sense

Substantial portfolio

If 4% of the portfolio comfortably covers expenses, the longevity protection of annuities adds little.

Inflation concerns

Most fixed annuities don't keep pace with inflation. Equity-heavy portfolios historically have.

Heirs you care about

Residual portfolio passes to heirs.

Flexibility valued

Want to spend more in early retirement (travel) and less later? Systematic withdrawal accommodates this.

Comfort with markets

Holding through a 30% drawdown without selling is essential for systematic withdrawal to work.

The hybrid approach

Many advisors recommend combining the two:

Example: $1,000,000 retirement.

The floor covers essentials regardless of markets or longevity. The portfolio covers discretionary; if markets do badly, you cut discretionary; if you live long, the floor remains.

For many retirees, this is the right answer.

What annuity to buy

If annuitizing, the choice matters. See AnnuityTypesAndAnalysis.

The simplest and usually best: single-premium immediate annuity (SPIA). Lump sum in; monthly payments out for life. Low fees; transparent; effective.

Avoid: variable annuities and indexed annuities for income purposes. High fees; complex; rarely the right tool.
