Enter a free-bet value, matched odds, and commission to calculate the lay side.
This calculation assumes a free bet where the stake is not returned. Check the promotion terms before placing either side.
Enter the free bet size and the odds you can back and lay at. The calculator compares stake-returned and stake-not-returned conversion, and shows the expected cash value after the exchange commission.
Back a selection with the free bet and lay the same outcome at the exchange. The calculator sizes the lay stake so most of the token's value converts to withdrawable balance.
Higher odds, typically 4.0 and above, convert more of the token when the bet is stake-not-returned. Low odds waste most of the bonus.
The stake itself is not returned on most bonuses, and the exchange takes a commission on winnings. The calculator shows the exact expected value after both.
