Bet Calculator

Work out the return and profit on a single, double, treble or accumulator. Enter each selection's odds in fractional, decimal or American format, set your stake, and the calculator shows the total return, the profit, and the combined odds.

How accumulator returns are calculated

Each selection's decimal odds are multiplied together to give the combined price, and the stake is multiplied by that combined price to give the return. Fractional odds convert to decimal by dividing the numerator by the denominator and adding 1 (5/2 is 3.50). Positive American odds convert as odds divided by 100 plus 1 (+150 is 2.50); negative American odds as 100 divided by the absolute value plus 1 (-200 is 1.50).
