Lottery Expected Value Calculator
Is your lottery ticket worth buying? Expected Value (EV) tells you the mathematical value of a $1 spent on any lottery ticket. When EV is positive, the ticket is theoretically worth more than it costs.
Formula: EV = (Jackpot × Cash Option × After-Tax Rate ÷ Odds) − Ticket Cost

How Expected Value Works
Expected Value (EV) is the average amount you can expect to win (or lose) per ticket over time. A positive EV means the lottery is theoretically worth playing; a negative EV means you'll lose money on average.
Example: If a lottery has a $500M jackpot, 1 in 292M odds, a $2 ticket, and 37% tax, the EV is: ($500M × 50% cash × 63% after-tax) ÷ 292M − $2 = -$1.46. You lose $1.46 per ticket on average.
When does EV go positive? For US Powerball, the jackpot needs to reach roughly $1.7 billion (advertised) for the ticket to be +EV. This has only happened a few times in history. Lotteries with better odds (like Peru Kabala at 1 in 1.9M) reach positive EV at much lower jackpot levels.
