Formula:
The core formula to determine your Lay Stake (LS) for converting a free bet (stake not returned) into guaranteed cash is:
LS = (S * (BBO - 1)) / (BLO - C)
- S: Free Bet Stake (e.g., £10)
- BBO: Bookmaker Back Odds (e.g., 4.0)
- BLO: Betting Exchange Lay Odds (e.g., 4.2)
- C: Exchange Commission (as a decimal, e.g., 0.05 for 5%)
The calculator then precisely determines your total guaranteed profit based on this optimal lay stake.
