An immediate annuity converts a lump sum into guaranteed lifetime income — starting within 30 days. A 65-year-old investing $500K gets ~$2,917/mo for life (7.0% payout rate). Insurance companies can offer higher rates than bonds because of 'mortality credits' — the actuarial advantage that some annuitants die early, funding longer-lived ones. The trade-off: your $500K is generally irrecoverable. Immediate annuities outsell deferred annuities and are the simplest retirement income tool.

📖 What is an Immediate Annuity?
A Single Premium Immediate Annuity (SPIA) pays you a fixed amount each month for life in exchange for a lump sum. Payments start within 30 days. No market risk — your income is guaranteed by the insurer's claims-paying ability. The insurance company pools your premium with other annuitants and uses actuarial tables to set payment amounts.
📊 SPIA Payout Rates
Payout rates rise with age (shorter life expectancy = higher rate). At 65, expect 6.5–7.5%. At 70, 6.9–7.5%. Joint & survivor and period-certain options reduce the rate because they extend the guarantee. Women typically receive slightly lower rates than men due to longer life expectancy.
⚖️ Immediate vs Deferred Annuity
Immediate: pay lump sum, get income now. Deferred: pay over time, convert to income later. Immediate suits retirees who need income today. Deferred suits savers building for future. Immediate annuities outsell deferred annuities among retirees who need guaranteed income right away.
💰 Tax Treatment
Qualified (IRA/401k): 100% taxable. Non-qualified: exclusion ratio = premium ÷ expected total return; that portion is tax-free return of principal. State rules vary. Some states exempt a portion of annuity income from state tax.
🎯 Best Age to Buy
65–75 is the sweet spot. Earlier = lower rates. Later = higher rates but fewer years. Consider laddering: buy a portion at 65, more at 70, more at 75 to average rates and reduce interest-rate timing risk.
📉 Annuity vs 4% Rule
4% rule: withdraw 4%/yr from portfolio, inflation-adjusted. Annuity pays ~7% but is fixed. Annuity guarantees lifetime income; 4% can fail if you outlive savings. Many use both: annuity for essentials, 4% for discretionary. The annuity provides longevity insurance; the 4% rule keeps flexibility.
📊 Mortality Credits Explained
Mortality credits are the actuarial advantage that makes immediate annuities pay more than bonds. When some annuitants die early, their unclaimed funds remain in the pool and fund payments for those who live longer. This 'pooling of longevity risk' allows insurers to offer higher rates than you could get from a bond ladder.
📋 Key Takeaways
- Income starts within 30 days of purchase
- Principal is generally irrecoverable — no liquidity
- Shop multiple insurers; rates vary by 10–20%
- Consider laddering purchases over several years
- Inflation-adjusted annuities exist but pay less initially
