How Does the Bonus Bet Calculator Work?
The Oddsy Bonus Bet Calculator shows you exactly how to turn bookmaker free bets into real withdrawable cash by hedging at a betting exchange. Maximize value, minimize risk, and make the most of every promotion—no guesswork needed.
What Is a Bonus Bet?
A bonus bet (or free bet) is a popular sportsbook promotion where you receive a stake to bet with, but only keep the winnings (not the stake itself). Our calculator helps you “lock in” a risk-free profit by laying against your bonus bet outcome at a betting exchange.
- Perfect for matched betting & bonus hunting
- No risk if you hedge properly
- Works with all major odds formats
How to Use This Calculator
- Enter your free bet value, the back odds (at the bookmaker), and the lay odds (at the exchange).
- Include the exchange’s commission if there is one (e.g., 2%).
- Switch odds format (decimal, American, fractional) as you prefer.
- See the optimal lay stake, guaranteed profit, and your profit margin!
