Bonus Bet Conversion Calculator

Bonus bets (or free bets) pay out winnings only, meaning you never get the stake back, so their real cash value is well below face value unless you convert them deliberately. The standard play: put the bonus on a longshot at one book, then hedge the other side with cash at another book so you collect roughly the same amount either way.

Enter the bonus amount, the odds you are placing it at, and the odds available on the opposite side. The calculator returns the exact hedge stake, your guaranteed profit, and the conversion rate. Placing bonus bets on underdogs around +250 to +400 typically converts 70% or more of the bonus into withdrawable cash.
