Cashback bonus calculator

When a bookmaker offers cashback on your qualifying bets, this calculator adjusts the lay stake so that the cashback flows through to your expected value.

Factor bookmaker cashback into your back-and-lay math.

Protect your cashback margin

Cashback edges are small. A 2.5% vs 5% exchange commission difference is often larger than the bookmaker promo itself.

Lay on BFB247 and keep the full cashback instead of handing half of it back to the exchange.
