TL;DR
Your annuity choice should match your longevity outlook. If you expect to live to 90+, life-only maximizes income. If uncertain or with health concerns, period certain protects your estate. Use the calculator to model payouts across different lifespan scenarios.
Why longevity matters
Annuity pricing assumes average life expectancy. If you outlive the average, you “win” with life-only. If you die early, the insurance company keeps the remaining principal. The key question: How does your personal longevity compare to actuarial averages?
Personal longevity factors
Factors suggesting longer-than-average life expectancy
- Parents lived to 85+
- Excellent current health, no chronic conditions
- Non-smoker, moderate drinker
- Regular exercise, healthy weight
- Higher education and income levels
- Married (married people live longer on average)
Factors suggesting shorter-than-average life expectancy
- Family history of early death (heart disease, cancer)
- Current health conditions (diabetes, heart disease)
- Smoking history
- Sedentary lifestyle
- Lower income and education correlation
Scenario modeling framework
Example: $100,000 premium at age 65
| Scenario | Years of Income | Life-Only Total | 10-Year Certain Total |
|---|---|---|---|
| Die at 70 (5 years) | 60 months | $39,000 | $79,200 + beneficiary gets $40,200 more |
| Die at 75 (10 years) | 120 months | $78,000 | $79,200 (guarantee met) |
| Die at 85 (20 years) | 240 months | $156,000 | $158,400 |
| Live to 95 (30 years) | 360 months | $234,000 | $237,600 |
Assumes $650/month life-only vs $660/month with 10-year certain
Payout option selection by longevity
High longevity confidence (expect 90+)
- Best choice: Life-only or minimal period certain
- Rationale: Maximize monthly income, you’ll collect for decades
- Trade-off: If wrong and die early, estate loses principal
Moderate longevity uncertainty (expect 80-90)
- Best choice: 10-year period certain
- Rationale: Protects estate if early death, modest payout reduction
- Trade-off: Slightly lower monthly income
Health concerns or family history (expect under 80)
- Best choice: 15-20 year period certain or cash refund
- Rationale: Ensures premium returns to estate
- Trade-off: Significantly lower monthly payout
Married with survivor needs
- Best choice: Joint survivor with appropriate percentage
- Rationale: Income continues for both spouses
- Trade-off: 15-30% lower initial payout
Longevity-adjusted comparison
Use this framework to personalize your analysis:
- Assess personal factors: Rate each longevity factor above
- Estimate personal life expectancy: Be realistic, not optimistic
- Model break-even ages: When does life-only beat period certain?
- Include spouse factor: If married, joint longevity matters
- Stress-test assumptions: What if you’re wrong by 5 years either way?
Real-life scenarios
Scenario 1: Healthy 65-year-old with long-lived parents
- Personal expectancy: 90+
- Recommendation: Life-only
- Rationale: 25 years of payouts, mortality credits compound
Scenario 2: 65-year-old with diabetes and heart disease history
- Personal expectancy: 75-80
- Recommendation: 10-15 year period certain
- Rationale: Protect estate, early death likely
Scenario 3: Healthy 70-year-old couple, similar ages
- Joint expectancy: One spouse likely to 90+
- Recommendation: Joint 75-100% survivor
- Rationale: High probability of survivor needing income

FAQ
What if my health changes after buying the annuity?
Annuity terms are fixed at purchase. If health improves, you benefit from higher mortality credits. If health declines, period certain protects your estate.
Should I buy an annuity if I have a terminal diagnosis?
Generally no—the insurance company would keep most of your premium. In this case, preserve liquidity for your estate or consider a medically underwritten annuity that accounts for your condition.
Do insurers check my health before setting rates?
Standard annuities don’t require health underwriting—they assume average life expectancy. Impaired-risk annuities (for those with health issues) may offer higher payouts because they expect shorter lifetimes.
