8/11 means that for every £11 you stake, you win £8 in profit if the bet wins. Your stake is returned on top of that, so a £11 bet at 8/11 returns £19 total.

The implied probability is 57.89%. This means the bookmaker prices this outcome as having roughly a 57.89 in 100 chance of happening.

These are odds on – your stake is greater than the potential profit. The bookmaker considers this outcome more likely than not.

How the Calculation Works

Winnings: Stake x (8 / 11) = Profit. So £10 x (8 / 11) = £7.27 profit.

Probability: 11 / (8 + 11) = 11 / 19 = 57.89%.

Decimal odds: (8 / 11) + 1 = 1.73. Multiply your stake by this to get the total return including your stake.
