An annuity trades a lump sum for a guaranteed monthly paycheck. This compares that paycheck against just investing the same lump sum yourself and withdrawing the same amount — set your lump sum and payout rate to see which one wins, and when.

Methodology & assumptions

  • The monthly payment is computed with the standard fixed-period amortization formula from your premium and payout rate — real annuity pricing also reflects insurer fees, mortality credits, and (for life annuities) your life expectancy.
  • A lifetime annuity is approximated as a fixed 25-year payout period; your actual life expectancy could be shorter or longer, which materially changes the real-world value of a life annuity versus this model.
  • The self-invested alternative assumes a constant annual return with no volatility, withdraws the exact same monthly amount the annuity would have paid, and ignores taxes on withdrawals or investment gains.
  • 'Breakeven' compares cumulative cash received from the annuity against total value delivered by the alternative (withdrawals taken so far plus the balance still invested) — it is not a guarantee either strategy performs this way in real markets.
  • No surrender charges, riders, inflation adjustment, or insurer default risk are modeled for the annuity.
