The Lotto Odds Calculator enables users to calculate the odds of winning the jackpot and additional prize levels for any given lottery.

If the lottery includes a bonus number, additional options will appear specifying the bonus variables. Alternatively, select a lottery from the Popular Lotteries drop-down menu to automatically display the odds table.
