🎟️ Lottery Annuity Calculator
Turn an advertised lottery jackpot into a year-by-year annuity payment estimate, including how much taxes take off the top.
How lottery annuities work
Most large U.S. lotteries advertise the jackpot as an annuity: instead of one lump sum, the prize is paid out in a series of payments over a set number of years (typically 30), with each payment increasing by a fixed percentage (typically about 5%) to help keep pace with inflation.
How this calculator works
Given the advertised jackpot as the total annuity value, this tool uses the standard growing-annuity formula to solve for the first payment, so that a series of payments growing at your chosen rate adds up to the full jackpot. It then estimates the final payment and applies your federal and state tax rates to show after-tax figures.
This is an estimate for general planning purposes only. Real payout schedules, withholding rules, and tax brackets are set by the lottery operator and tax authorities and can differ from this simplified model.
