Convert any free bet or risk-free bet into guaranteed cash. Enter your odds below and see exactly how much profit you can lock in.
Every sportsbook sign-up bonus comes with a free bet or risk-free bet. The trick is converting that bet into real, withdrawable cash. This calculator does the math for you: enter the bet amount, your back odds, and the opposing lay odds to see your guaranteed profit and optimal lay stake.
Free Bet: Your stake is not returned if the bet wins. You only receive the profit portion. Most sign-up bonuses (DraftKings, FanDuel, BetMGM) work this way. Typical conversion rates land between 70-80%.
Risk-Free Bet: You get your original stake back plus the winnings if the bet wins. If it loses, you receive a free bet credit for the amount risked. Conversion rates are higher, often 80-95%.
