How to use the calculator

1

Enter the odds from each bookmaker for the same event. E.g. Bookie A has Team 1 at 2.10 and Bookie B has Team 2 at 2.05.

2

Enter your total stake — the total amount you want to spread across both bets.

3

Check the status. If "Arbitrage Found" lights up green, there's an opportunity. The calculator shows how to split your stake.

4

Use the rounded amounts (green) when placing bets. Green "Safe to place" means both outcomes are profitable with rounded stakes. Red warning means the edge is too thin — use exact amounts or increase your stake.

5

Always verify odds in your bookmaker apps before placing. Odds can change at any time.
