4/7 means that for every £7 you stake, you win £4 in profit if the bet wins. Your stake is returned on top of that, so a £7 bet at 4/7 returns £11 total.

How the Calculation Works

Winnings: Stake x (4 / 7) = Profit. So £10 x (4 / 7) = £5.71 profit.

Probability: 7 / (4 + 7) = 7 / 11 = 63.64%.

Decimal odds: (4 / 7) + 1 = 1.57. Multiply your stake by this to get the total return including your stake.
