Annuity Payout Comparator

Guaranteed income vs. self-managed growth — the real math.

Choosing between a lump sum payout and a guaranteed monthly annuity — from a pension, structured settlement, or lottery winning — involves a genuine tradeoff between the annuity's guaranteed income regardless of market performance or longevity, and the lump sum's potential to grow faster than the annuity's implied rate if invested well, with the real risk of running out early if managed poorly. This calculator runs both scenarios: how the lump sum would grow if invested and left untouched, and separately, how long the lump sum would actually last if withdrawn at the same monthly rate the annuity pays, given your assumed investment return.

• →Calculates how a lump sum would actually grow over time if invested and left untouched
• →Separately calculates how long the lump sum would last if withdrawn at the annuity's monthly rate
• →Compares total annuity payout against both lump-sum scenarios with your own assumed return
• →Explicitly notes what the calculation doesn't capture — guarantees, longevity risk, and other annuity features
