This calculator is built for no-sweat bets where the stake comes back as cash or bonus credit if the bet loses. It is most useful when the market has exactly two outcomes and no push risk, because pushes often lead to losing a promotion.

Enter the odds and stake for the promo bet. If you want to improve the target odds by a percentage, click Adjust, enter the boost, and apply it. For example, +220 with a 33% boost becomes about +293. If you already have a stake entered, you can also use Adjust to change the net payout by a dollar amount. For example, -220 with a $100 stake and a $5 payout increase moves to about -198.

Enter the opposing odds you want to hedge with. If the best hedge price only works up to a certain stake and then gets worse, use Add option to include another hedge price tier. That lets the calculator combine multiple hedge levels into one result.

The bonus value slider tells the calculator how much the returned bonus bets are worth in cash terms. A standard starting point is 0.70, meaning you value the bonus at 70% of face value. As a rough target, a $100 no-sweat bet valued at 0.70 should usually produce around $45 or more in guaranteed profit after a good hedge. If the promotion returns cash instead of bonus bets, choose Cash back so the value becomes 1.00.

After you press Calculate, the results panel shows the total stake required, the calculated hedge amount, and the guaranteed profit. The profit stays the same no matter which side wins. If the hedge wins, no extra capital is needed beyond the hedge you already placed.
