How to Use This Calculator

Back Stake → Lay Stake

Use this direction when you've already placed or decided on your back bet at the bookmaker and need to know the correct lay stake to place on the exchange to offset it.

Lay Stake → Back Stake

Use this direction when you know how much you want to lay on the exchange — for example due to exchange liquidity limits — and need to know the equivalent back stake.

Lay Liability

Your liability is the amount the exchange holds from your balance to cover your lay bet. If the selection wins, the exchange pays out from your liability.

Break-Even Odds

The lay odds at which your back and lay positions perfectly cancel out — zero profit and zero loss. If your lay odds are below break-even, you're in profit.
