How to work out bet profit
With decimal odds, profit is the stake times the odds minus one, and the total return is the stake times the odds. With fractional odds, profit is the stake times the fraction.
Profit = stake × (decimal odds − 1) · Return = stake × decimal oddsWorked example
A £10 bet at 5/2 (3.50) makes £25 profit and returns £35 including your stake. The same bet as a free bet returns just the £25, because the stake is not paid back.

How to Calculate Bet Profit
Every punter needs to know what a bet pays before placing it, yet it often causes confusion, especially when switching between fractional and decimal odds. The calculator gives you the profit, total return, implied probability and ROI for any single bet straight away.
Profit vs total return: what is the difference?
These two figures are often confused. Profit is what you win on top of your stake. Total return is the profit plus your stake back. A £10 bet at 3.50 returns £35 in total: £25 profit and your £10 stake. Most bet slips show the total return, so remember that part of it is your own money coming back.
Calculating profit from decimal odds
Decimal odds are the simplest format. Profit = (decimal odds − 1) × stake, and total return = decimal odds × stake. At 4.00 on a £20 stake, profit = 3 × £20 = £60 and the total return = 4 × £20 = £80. Our odds converter turns any format into decimal.
Calculating profit from fractional odds
Fractional odds show profit relative to stake. At 5/2, every £2 staked wins £5 profit. Profit = (first number ÷ second number) × stake. At 5/2 on a £10 stake, profit = (5 ÷ 2) × £10 = £25, and the total return is £35. Fractional odds are still the norm in UK horse racing.
Calculating profit from American (moneyline) odds
American odds work differently for underdogs (positive) and favourites (negative). For positive odds such as +250, profit = (odds ÷ 100) × stake, so £10 at +250 makes £25 profit and returns £35. For negative odds such as −150, profit = (100 ÷ 150) × stake, so £10 at −150 makes £6.67 profit and returns £16.67. UK bettors mostly see American odds on NBA, NFL and other US sports.
Profit from a free bet
Most free bets are stake not returned (SNR): if the bet wins, you get the profit but not the free bet stake. So a £10 free bet at 5/2 pays £25, not £35. Switch the calculator to Free bet to see this. To turn a free bet into a locked-in amount whatever the result, use our free bet calculator.
What is implied probability?
Every price implies a chance of that outcome happening. Implied probability = 100 ÷ decimal odds, so 3.50 implies 28.57%: at that price you would expect to lose roughly seven times in ten. Implied probability is the basis of value betting: if you think the real chance is higher than the implied figure, the bet has value. Use our expected value calculator to put a number on it.
ROI and bankroll management
ROI (return on investment) is your profit as a percentage of your stake. A winning bet at 3.50 has an ROI of 250%: the profit is two and a half times the stake. Tracking ROI across all your bets over time is one of the most useful habits a bettor can have. Our bankroll management calculator helps you size stakes with percentage staking or the Kelly Criterion.

Frequently Asked Questions
How do I calculate profit from odds?
For decimal odds, profit = (odds − 1) × stake. For fractional odds, profit = (first number ÷ second number) × stake. For positive American odds, profit = (odds ÷ 100) × stake, and for negative American odds, profit = (100 ÷ the odds without the minus sign) × stake. The calculator handles all three.
What is the difference between profit and total return?
Profit is what you win on top of your stake. Total return is the profit plus your stake back. A £10 bet at 4.00 returns £40 in total, which is £30 profit and your £10 stake. Bet slips usually show the total return.
How much do I win on a £10 bet at 5/1?
A £10 bet at 5/1 makes £50 profit, and you get your £10 stake back too, so the total return is £60. In decimal odds 5/1 is 6.00, and £10 × 6.00 = £60. As a stake-not-returned free bet, it would pay £50.
What does implied probability mean?
Implied probability is the chance of an outcome that a price suggests, worked out as 100 ÷ decimal odds. Odds of 2.00 imply 50% and odds of 4.00 imply 25%. If you think the real chance is higher than the implied figure, the bet has positive expected value.
Can I use this calculator for each way bets?
This calculator is for win-only single bets. For each way bets, use our each way calculator, which works out the win and place parts separately with your bookmaker’s place terms.
