22/1 means that for every £1 you stake, you win £22 in profit if the bet wins. Your stake is returned on top of that, so a £1 bet at 22/1 returns £23 total.

The implied probability is 4.35%. This means the bookmaker prices this outcome as having roughly a 4.35 in 100 chance of happening.

These are odds against – the potential profit is greater than your stake. The higher the first number relative to the second, the less likely the bookmaker thinks the outcome is.

How the Calculation Works

Winnings: Stake x (22 / 1) = Profit. So £10 x (22 / 1) = £220.00 profit.

Probability: 1 / (22 + 1) = 1 / 23 = 4.35%.

Decimal odds: (22 / 1) + 1 = 23. Multiply your stake by this to get the total return including your stake.
