🎰Lottery Expected Value Calculator
e.g. 10000000
UK Lotto: 45,057,474
The expected value (EV) of a lottery ticket is the average return per ticket purchase, calculated as the jackpot divided by the odds of winning, minus the ticket cost. Almost all lottery tickets have negative expected value — they are, mathematically, a losing proposition.
