Using the reliable Racing Post Bet Calculator will allow you to work out your returns for bets like Lucky 15, Doubles, Yankee, Accumulator and much more. So a stake of £1 would pay £4 profit, plus your stake back, which is a total return of £5.Ĭalculating your winnings from a single selection is fairly straight forward, however, when placing more complex bets or multiples it’s advised you use an odds calculator. The winnings you would receive from a bet is calculated by multiplying your stake by the odds. For example, if the odds are 4-1 this suggests there is a 1 in 5 chance of winning (4+1), or calculated as 1 / (4+1) = 0.2 which means there is a 20% chance of the outcome happening. Betting odds are calculated by the probability of something happening.
