How to use this calculator

Enter your bookie stake, the back odds, the exchange lay odds, and the exchange commission. The calculator tells you exactly how much to lay so your result is the same whether the bet wins or loses.

Use Qualifying bet for real-money bets (your stake is returned if it wins), and Bonus bet (SNR) for bonus bets where the stake is not returned.
