Betting Calculators That Do the Maths for You
A betting calculator works out a price, a stake or a payout from the numbers you type. Seven betting calculators and checklists live on this site, each on the page that explains it. Pick by the question: odds in another format, what commission does to a price, how to lay or cover a bet, which broker opens the places you want, why a stake was cut, what to have ready at sign-up. Every one is free, works in your browser, and nothing you type is sent anywhere.
What do you need to work out?
Sums go wrong quietly. Odds read in the wrong format. Commission worked out on the stake when it belongs on the net profit of the market. A lay stake mistaken for the amount at risk. Nobody notices until the money moves.
Find your situation below and follow the line. If back, lay and commission are still new words, start with the exchange betting guide and come back.

Reading a price
Is the price on the screen the price you keep?
One price, six formats
Type one price and read it in all six formats, with the probability behind it. A probability, or a prediction-market price in cents, comes back as decimal odds, and a market of two or three outcomes shows its margin.
Open the converterYour price after commission
For a back, enter the stake, the decimal odds and your rate. You get the profit, the commission, the net profit and the effective odds. It also finds the exchange price that matches a bookmaker’s, and the commission on a back followed by a lay on the same selection.
Open the calculatorBookmaker against exchange
Set a bookmaker’s price against an exchange’s. You get the effective odds after commission, the gap, and the rate at which the two prices tie. On a market of two or three outcomes, it shows which side is higher on each.
Compare the pricesLaying and covering
How do you take the other side of a bet you already hold? By laying it. What you collect is one figure; what you pay if the selection wins, the liability, is the figure to read twice.
Before you open an account
What has to be settled before the first deposit, and what can cap a stake after it?
Which broker opens your places
Choose the bookmakers, exchanges and markets that must share one account. Brokers that miss any of them drop off the list; the rest stay, each with the name of its own tool.
Tick your placesWhy a stake gets capped
Your stake runs against sample offers, one price at a time, down to the lowest odds you accept. A winnings cap becomes the highest stake that fits under it. A smaller allowed stake shows what a month costs on an edge you assume.
Open the explainerWhat to have to hand
A short list to have ready: photo ID, proof of address, a phone or webcam for a selfie, an e-mail address you can open, and the first deposit. Tick what you hold, name your broker, and read what is still missing, what its form asks and the deposit it needs.

Three more sums sit inside guides: splitting stakes across two or three prices, settling an Asian handicap line and, in the pro betting roadmap, how a run of bets can swing around a real edge.
Take the rate from your broker’s page, or from the terms of the exchange you use, and type it in yourself. A result is a calculation, not a forecast and not a tip on what to stake. Over time the usual result is a loss, and no sum changes that.
Read the example first
Each calculator opens on an example that is already filled in, so you can watch the sum run before you type anything, and the figures in it only show how the sum works and describe no market, so read it once and then replace every figure with your own.
Sums done, the next question is the door. The routes into the exchange sit in one place, the four brokers side by side set deposits, ID checks and turnover against each other, and the broker overview lays out the places each account opens.
