This calculator is for promos where your first bet must win in order to unlock the bonus award. It is best for clean two-outcome markets with no push risk, because a push can ruin the promotion leaving you without the bonus payout and a pushed hedge.

Enter the odds and stake for the qualifying bet, and enter the bonus amount in the Bonus Bet Amount If Win field for the bonus you receive if it wins. 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. If you hedge with a bonus bet, check Use bonus bet for that hedge leg. That can be a big boost to profits because the hedge side is often an extreme underdog and bonus-bet hedge value can improve the overall setup.

The bonus value slider tells the calculator how much the unlocked bonus bets are worth in cash terms. A standard starting point is 0.70, meaning you value the bonus at 70% of face value. That is the number you should use if you want the calculator to estimate the cash-equivalent value of the bonus award.

After you press Calculate, the results panel shows the total cash stake required, the calculated hedge amount, the guaranteed cash profit, the bonus amount unlocked if the must-win side wins, and the effective If Win odds. If the hedge wins, no extra capital is needed beyond the hedge you already placed. If the must-win side wins, you unlock the bonus amount and need additional capital to hedge those bonus bets.
