Bonus conversion is the process of turning sportsbook free bets, site credits, or bonus bets into real, withdrawable cash. Since free bets only pay out winnings (not the stake), you hedge by betting the opposite outcome with real cash to guarantee a profit regardless of which side wins.
A good conversion rate for standard free bets is 70-80%. This means converting a $100 free bet into $70-$80 guaranteed cash. Rates depend on the odds available—longer odds (like +300 vs -350) typically yield higher conversions. Some promotions with stake-returned bonuses can convert at 90%+.
Place your free bet on one outcome (ideally at plus odds), then bet real cash on the opposite outcome at another sportsbook. The calculator determines the exact hedge amount so you profit no matter which side wins. Use the highest odds you can find on both sides to maximize your conversion rate.
Free bets only return winnings—if you bet $100 at +200 and win, you get $200 (not $300). Site credits or bonus cash return both stake and winnings, so a $100 site credit at +200 pays $300. Site credits convert at much higher rates (often 90%+) than standard free bets.
It's possible but much harder. Without multiple books, you're limited to betting both sides at the same sportsbook, which often violates terms of service and offers worse odds. Having accounts at 3-5 sportsbooks gives you better odds to shop and higher conversion rates.
