Bet credit calculator
A bet credit, which bookmakers often call a free bet, comes with conditions, and it is worth less than cash because a winning bet credit usually pays only the profit. This calculator works out its expected value with the same formula as our cards: amount times (odds minus one) times (one minus the margin), divided by the odds. When the stake is returned, the value is the amount times (one minus the margin). If the offer needs a qualifying bet first, enter its stake and the calculator subtracts its expected cost, the stake times the margin. The default margin is 5 %, the figure our method uses until a market-specific source is chosen.

How this is calculated
A bet credit is placed once at odds of at least 2.5 or the minimum odds in the terms. Without the stake returned, its value is amount × (odds − 1) × (1 − margin) ÷ odds; with the stake returned it is amount × (1 − margin). A qualifying bet costs its amount × the 5 % margin on average.
