About the Mega Millions Payout Estimator

Like Powerball, Mega Millions winners choose between an immediate reduced lump-sum cash payment or the full advertised jackpot spread across 30 graduated annual installments. The cash option reflects the present value of those future payments.

Formula: Cash Value = Jackpot × Cash Value % · After-Tax Amount = Amount × (1 − Combined Tax Rate)

Cash value percentages fluctuate with prevailing interest rates, so adjust the default to match the actual estimated cash value published for the specific drawing you're evaluating.
