An annuity is a contract with an insurer that either pays out a lump sum as guaranteed income (the payout phase) or grows contributions at a stated rate (the accumulation phase). Real annuity quotes vary with age, fees, riders, and prevailing interest rates, so many investors treat calculators like this one as a first approximation before comparing actual contracts.
