Pension Lump Sum vs Annuity Calculator
Compare pension lump sum payout versus monthly annuity payments.
Find which option gives you more total value over time.
Pension lump sum vs annuity is one of the most important retirement decisions. A lump sum gives you a large one-time payment, while an annuity provides steady monthly income for life.
Annuity total value formula:
Total Annuity Value = Monthly Payment × 12 × Years of Payments
Lump sum future value with investment:
Future Value = Lump Sum × (1 + Annual Return)^Years
Key factors to compare:
| Factor | Lump Sum | Annuity |
|---|---|---|
| Control | Full control of money | No control, fixed payments |
| Risk | Investment risk is yours | Pension fund bears the risk |
| Inflation | Can invest to beat inflation | Usually fixed (no inflation adjustment) |
| Longevity | Can run out | Guaranteed for life |
| Inheritance | Remaining balance passes to heirs | Payments typically stop at death |
Break-even analysis: The “break-even point” is how many years of annuity payments it takes to equal the lump sum. If you expect to live beyond this point, the annuity may be better.
Break-even Years = Lump Sum / (Annual Annuity Payment)
Investment return assumptions:
- Conservative: 4–5% annually (bonds, CDs)
- Moderate: 6–7% annually (balanced portfolio)
- Aggressive: 8–10% annually (stocks)
Practical considerations:
- If you have other guaranteed income (Social Security, rental income), a lump sum may give you more flexibility.
- If you have no other guaranteed income, the annuity provides a safety net.
- Consider your health and family longevity when estimating how long you will receive payments.
- Some pensions offer survivor benefits (reduced payments to your spouse after your death).
Tip: Many financial advisors suggest the annuity if you expect to live 20+ years in retirement and have no other guaranteed income sources.
