A matched betting calculator is a tool that helps you work out the correct stakes for your back bet with a bookmaker and your lay bet on a betting exchange. Just enter the odds, stake, exchange commission, and bet type, and the calculator returns the exact lay stake, liability, and expected profit—so you can aim for the same result regardless of the outcome.
It’s like having the tricky part handled for you. Instead of doing calculations by hand, you enter your details and the calculator does the work. This reduces errors, clears up uncertainty, and helps you focus on completing offers efficiently.
Our matched betting calculator takes a look at the odds for your back bet and lay bet, and then figures out the perfect stakes you need. Let me break it down for you in four easy steps:
You can easily learn how to do matched betting and make more money with AiProfit's set of betting tools, which includes the matched betting calculator, OddsMatcher, and more. To make sure you take full advantage of any betting opportunity, these tools handle the calculations and help you stay fast, accurate, and consistent.
A matched betting calculator works by using your back odds, lay odds, stake, and exchange commission to calculate the correct lay stake, liability, and expected profit. This helps you keep your results similar regardless of the event outcome.
Lay stakes are calculated by balancing the bookmaker odds against the exchange odds while factoring in commission. A matched betting calculator does this instantly, reducing the chance of manual calculation errors.
Profit is calculated by combining the result of your back bet and lay bet. For free bets, profit depends on the conversion value of the bonus. A matched betting calculator shows your expected profit before you place any bets.
Liability is the amount you risk on the betting exchange if your lay bet loses. The calculator shows this clearly so you know how much needs to be available in your exchange account before placing the lay bet.
To back and lay correctly, you place a back bet with a bookmaker and lay the same outcome on an exchange. Using a calculator ensures the stakes are aligned so your risk is controlled and predictable.
Enter your back odds, lay odds, stake, and exchange commission into the calculator. It will instantly show the lay stake, liability, and expected profit, helping you decide whether to place the bet.
Matched betting works when bookmaker promotions are available and calculations are done accurately. Using tools like a matched betting calculator helps reduce losses and improves consistency.
Matched betting can produce near-guaranteed results when bets are calculated correctly, especially when using free bets. A calculator helps minimise qualifying losses and lock in predictable outcomes.
Manual calculations are slow and prone to errors. A matched betting calculator is faster, more accurate, and shows liability and profit instantly—making it safer and more efficient.
