Free Casino Calculators
These three free calculators do the maths so you don't have to guess. Each one runs thousands of simulated sessions in your browser to show you what an offer, a budget or a stake is realistically worth — the most likely outcome, plus the range you could actually land in. No sign-up, no spin, no promises: just honest numbers to help you make a clearer-headed decision before you play. They're educational tools for over-18s, and every result is a statistical estimate rather than a guarantee.
Bonus Wagering Calculator — Is the Offer Worth It?
Punch in a bonus offer and a game to see your expected value, the odds of clearing the wagering, and the spread of likely results.
Casino Bankroll Calculator — How Long Will It Last?
Set a bankroll and a bet size to estimate how long your money lasts, your chance of losing it all, and your expected loss.
RTP Calculator — Expected Return & Loss by Game
Enter a stake and a number of spins to see your expected return or loss on a given game, with a realistic best-to-worst range.
