Lottery Annuity vs Lump Sum Calculator

The advertised jackpot is the total annuity, while the cash option is the current amount offered instead. The ratio varies by drawing and funding conditions. The calculator's 56 percent default is an editable scenario, not a current lottery quote. Enter the official cash option for the drawing you are modeling.

Powerball switched to graduated payments in 2014 specifically because flat $33M-a-year checks lose buying power to inflation. The 5% annual graduation roughly offsets long-run US CPI inflation plus a real growth premium, so payment 30 has comparable purchasing power to payment 1. The math: payment 30 equals payment 1 multiplied by 1.05 raised to the 29th power, which is about 4.12x. On a $500M advertised jackpot, payment 1 is about $7.5M and payment 30 is about $31.1M. The 30 payments still sum to the advertised $500M because the first payment is back-solved from the geometric series total. Mega Millions adopted the same 5% graduation model and 30-year, 29-installment-plus-first-payment-immediate schedule, so the math here applies to both games.

The 24 percent figure is generally withholding on certain gambling winnings, while 37 percent is the top 2026 federal marginal rate. Withholding is a prepayment, and the top marginal rate is not automatically the effective rate on every dollar. The calculator's flat tax input is a scenario, not a tax-return calculation.

Lottery tax can depend on residence, ticket location, source rules, lottery-specific exemptions, and local tax. Residence when a payment arrives is not the only factor, and moving may not remove source-state obligations. Use the calculator's state rate only as a scenario and verify every relevant jurisdiction before claiming.

The discount rate converts future annuity payments into today's dollars, so a higher assumed after-tax return lowers their present value. The break-even rate is only a mathematical scenario. It does not account for investment risk, fees, changing tax law, estate planning, creditor protection, or personal circumstances. The calculator cannot recommend the lump sum or annuity.
