Free Bet Calculator

It's great being able to bet with free bets after claiming a bookies new customer offer - but it's even better working out how much you'll win if your free bet's a winner!

We've made it easy for you to calculate the potential winnings from the free bets you place thanks to the free bet calculator below courtesy of BetVictor.com.

How to Use The Bet Calculator

The bet calculator is really easy to use, simply enter the number of selections, the odds that you're betting at, the bet type, and the value of your free bet (your stake).

Once you've entered all of your bets details, a quick click/tap of the blue “CALCULATE” button will show you the free bets potential winnings.

The bet calculator will even work out how much you'll win if the bookie allows you to use your free bet on more complicated bets such as Accumulator’s or Lucky 15 bets.

Simply “Choose your bet type” before entering your stake into the free bet calculator.
