Free Bet Calculator
A free bet calculator works out how much profit you can extract from a stake-not-returned free bet. Enter your free bet amount, back odds, and lay odds, and the calculator shows your required lay stake, exchange liability, and net profit after commission — so you know exactly what you'll make before you place.
