Our lottery calculator helps you understand the true odds and expected value of playing the lottery. Enter your ticket price, frequency of play, and time period to see the mathematical reality of lottery gambling.
Lottery odds are astronomical. Powerball has odds of 1 in 292 million, while Mega Millions is 1 in 302 million. These calculators show you the probability of winning over your lifetime of playing, which remains extremely low even with regular play.
Expected value shows the average return per dollar spent. For most lotteries, this is negative, meaning you lose money on average. Our calculator shows you exactly how much you can expect to lose over time.
