Lump Sum: Control and Risk
A lump sum gives you control and flexibility. You can invest it, spend it, or pass it to heirs. However, you bear all investment risk, longevity risk (outliving your money), and inflation risk. A lump sum also triggers immediate taxation unless rolled into an IRA.
Monthly Annuity: Guaranteed Income
A monthly annuity provides guaranteed income that cannot be outlived, often includes cost-of-living adjustments (COLA), and spreads taxes over time. However, payments typically stop upon death (unless you choose a survivor option), and you lose control over the principal.
The Breakeven Age
The breakeven age is a critical metric: the age at which cumulative monthly payments exceed the lump sum value (adjusted for investment returns). If you expect to live beyond this age, the annuity is typically better. If you have health concerns or prefer flexibility, the lump sum may be more appropriate.
