Calculate Mega Millions jackpot combinations, ticket probability, multi-ticket chance and an illustrative jackpot-only expected value.
Probability calculation only. The jackpot-only expected value excludes lower-tier prizes, split jackpots, taxes, ticket rules, local availability, annuity terms and changing prize pools. Lottery games are games of chance; do not treat this as financial advice.
Method: Jackpot combinations equal the number of ways to choose the main numbers multiplied by the separate bonus-number pool where applicable. The multi-ticket chance is one minus the probability that every ticket misses.
Inputs used: Currency = USD; Tickets or plays = 1 tickets; Cost per ticket = 5; Illustrative advertised jackpot = 100,000,000; Illustrative cash-value percentage = 50 %
Assumptions: The result uses the values, units and options shown in the input snapshot.
Scope and warnings: Probability calculation only. The jackpot-only expected value excludes lower-tier prizes, split jackpots, taxes, ticket rules, local availability, annuity terms and changing prize pools. Lottery games are games of chance; do not treat this as financial advice. Rounding and excluded real-world terms can make an external result differ.
