How does this calculator help?

Matched betting lets you profit from bookmaker offers using precise calculations. This calculator automatically computes the optimal lay stake and liability for both ‘Qualifying’ and ‘Free Bet’ (SNR) modes in real-time—helping you minimise losses or lock in guaranteed profit.

‘Liability’ is the risked amount you must have in your exchange account when laying a bet. Commission is the small % the exchange charges on wins. Results differ between modes because in Free Bet mode, you keep the winnings only, not the returned stake.
