About this calculator
A fixed annuity pays out a constant monthly amount over a set period. The math is the same as a mortgage in reverse — given principal, rate, and term, find the payment that fully amortizes the principal plus interest. A $200k annuity at 5% over 20 years pays ~$1,320/mo, returning $317k total ($117k interest).
Frequently asked
Same math, opposite direction. A mortgage you pay; an annuity pays you. The PMT formula is identical.
