Lottery Annuity Calculator
Calculate 30-year graduated lottery annuity installments versus immediate post-tax cash lump sums with federal and state taxes.
What is the Lottery Annuity Calculator?
Lottery payout modeling compares the immediate lump-sum cash option against graduated thirty-year annuity payout schedules for major lottery jackpot prizes. It computes net after-tax proceeds factoring mandatory federal tax withholdings, tiered state tax brackets, and discounted present value cash option discount rates. This provides jackpot winners with essential financial clarity to evaluate reinvestment yields, manage tax liabilities, and make informed lump-sum versus annuity decisions.
