How these work
Matched betting is two opposite bets on the same thing: you back it at a bookmaker and lay it at a betting exchange. Whichever way the result goes, one bet wins and one loses, and the calculator tells you the stake that makes the two cancel out. The cost or gain is the gap between the two prices plus commission.

FAQs
Are the calculators free?
Yes, there are no accounts and no sign-up. Everything runs in your browser and nothing you type is sent anywhere.
Which calculator should I use first?
For a normal sign-up offer: the matched betting calculator for the qualifying bet, then the free bet calculator for the free bet you earn. Each way and dutching are for later, and the Lucky 15 calculator is for +EV bets that swing, once you have a float.
Can I trust the maths?
Every formula is shown on its page, and each calculator is unit-tested against worked examples. Check your own numbers with a small bet first, and always confirm both bets are matched.
