Calculate your lay stake and guaranteed profit.
Matched Betting Calculators: The Math Behind Every Bet, Done For You

Betting math gets complicated fast — lay stakes, commission, free-bet conversion, dutching splits, hedge amounts. One wrong number and a "guaranteed" profit turns into a loss. Our Calculators suite handles the math for every major betting strategy in one place, so you can plug in your numbers and get an exact answer instead of doing it by hand. It covers matched betting, dutching, each-way, hedging, odds conversion, parlays, and probability.
