How to Calculate Returns on a Single
The simplest way to calculate your winnings with fractional odds is to first convert them into decimals. To do this, follow the steps below:
Add the first number (numerator) to the second number (denominator) of the fraction
Divide this number by the denominator to work out your decimal odds
Multiply the decimal odds by your stake to work out your return
For example, if you bet £8 on a team to win at odds of 11/4, then for every £4 you put on at that price you would receive £11 back in winnings, plus your stake. The total return on this wager is £30 – £22 of profit, plus the £8 original stake.
How to Calculate Returns on a Double
Doubles and accumulators are calculated in a similar way to single bets. Again, you start by converting your fractional odds into decimals:
Convert the fractional odds to decimal odds for each bet
Multiply all of the decimal odds together to find out your total odds
Multiply your total odds by your wager to find out your return
For example, say you’ve backed two horses both to win at 4/1 and 5/1 with a £5 stake. You get a predicted return of £25 from the first leg, then that rolls onto the second leg as the stake. This double thus returns a total of £150, with £145 of that being profit.
