Betting Calculators

Swap between decimal, fractional and American prices and see the win chance each one implies.

Measure a price against your own probability and see whether the bet makes money over time.

Turn your edge into a stake size, with full, three-quarter, half and quarter Kelly settings.

Total up a market's prices to expose the bookmaker's margin and the fair odds underneath.

Find the exchange lay that locks in profit mid-match, and check it against the bookie's cash-out offer.

Back two, three or more outcomes with one stake and get the same payout whichever comes in.

Stake every outcome across bookmakers for a guaranteed return, with four staking plans to pick from.

Multiply up to 15 legs, win or each way, and watch the potential return grow leg by leg.

See the win, place and losing returns on any each-way bet, whatever the place terms.

Work out what a stake-not-returned or stake-returned token actually pays at your chosen price.
