Lottery & Gambling Calculators

Lottery headlines quote the jackpot, but the number a winner actually receives depends on the choice between lump sum and annuity, the tax picture and the cash value behind the advertised prize. These calculators work through that choice, along with the smaller maths of raffles and poker equity.

The advertised Powerball jackpot is an annuity total, not a check.

The advertised Mega Millions jackpot is not what a winner banks.

Win a Mega Millions jackpot and you face a famous choice: 30 graduated annuity payments or one lump-sum cash payment.

A $100 million jackpot is not $100 million in your bank account.

Enter what you stake, your honest chance of winning, and the profit you would make if you win, and this calculator returns the expected return per bet: the long-run average profit or loss hiding inside those three numbers.

Splitting a prize pool sounds simple until the cents stop adding up.

Pot-Limit Omaha equities run much closer than Hold’em, which is exactly why guessing is expensive.

Your winning chance in a raffle is simply your share of the tickets actually in the draw, yet most raffle tools stop at that single number.

At a final table, a stack is not just chips: it is a share of whatever prize money is left on the table.
