How Much Can You Win on Sports Bets? Use Our Odds Calculator
An odds calculator shows what you stand to win from a bet. The idea is simple: you enter your stake and the odds offered by the bookmaker. The calculator then applies the formula and displays the possible return. In short, it answers the fundamental question — how much will you get if your bet wins?
How to Calculate Odds?
Fractional odds show the profit you make from a bet, not the total payout. The fraction indicates how much you win in relation to your stake.
Example: Odds of 3/5
This means: You win £3 profit for every £5 you bet. So if you bet £50, here’s how to calculate:
Formula: (Stake × Top Number) ÷ Bottom Number = profit
Place £50 mean: (£50 × 3) ÷ 5 = £30 profit
Your total return is: £30 profit + £50 stake = £80 total
This is the core principle behind every betting odds calculator — it automates the maths and shows the profit figure instantly.
How to Work Out Winnings from Odds?
Fractional odds show profit. Add your stake to get the total payout.

Bookmakers don’t set prices at random. Their analysts weigh team form, player stats and injuries, then decide the favourite. That side gets shorter odds, the underdog longer ones. Into every price goes the bookmaker’s margin — their guaranteed cut.
Odds also move with money. If punters pile on one outcome, the bookmaker cuts the price to limit exposure. The other side drifts.
Higher odds mean bigger potential profits, but also bigger risk. A £50 stake at 4/5 pays £40 profit, at Evens £50, at 5/1 a much bigger £250.
To understand how much you can win from a single bet, you need to calculate the stake. You can either use our odds winnings calculator or calculate the winnings yourself by multiplying the stake amount by the prices.
The same applies in outrights. Before the World Cup in Brazil, the hosts were 3/1, Argentina 4/1, Germany 9/2, Spain 7/1. Brazil was the favourite, but a punt on Spain offered a £700 profit from £100, with a lower probability.
Not every bet ends in a win or a loss. Some markets, such as Asian handicap or totals, can be pushed. These settle at 1/1, meaning you simply get your stake back.
How to Calculate Winnings on an Accumulator?
An accumulator, or acca, joins several bets into one. The odds of each selection are multiplied together. That total figure is then applied to your stake.
Formula:
- Odds of leg 1 × Odds of leg 2 × Odds of leg 3 = Acca odds
- Acca odds × Stake = Profit
Example 1: A three-fold acca
You back Arsenal to beat Fulham at 4/6, Chelsea to beat West Ham at 1/2, and Spurs to beat Everton at 13/10. Multiply the odds:
- 4/6 × 1/2 × 13/10 ≈ 13/15.
A £100 stake returns about £86 profit: add your stake and the total payout is £186.
Example 2: Adding another leg
Now you add Manchester United at Evens (1/1) to make it a four-fold. Multiply again:
- 4/6 × 1/2 × 13/10 × 1/1 ≈ 13/15 × 1/1 = still around 13/15.
The profit rises to roughly £86 on top of the £100 stake, but the risk has grown — four results must all land.
Example 3: Longer prices
Say you go for three outsiders: Wolves at 5/1, Nottingham Forest at 7/2, and Brighton at 3/1. Multiply them:
- 5/1 × 7/2 × 3/1 = 105/2.
A £20 stake brings a profit of £1,050. Add your £20 and the total payout is £1,070. The lure is obvious, but so is the risk.
All legs must win. One slip and the acca is lost.
Use our winning odds calculator to combine all fractions and get the result instantly.
Fractional odds also hide the chance of an outcome. 1/2 equals 66.7%, 5/1 equals 16.7% etc. Often, it's more important to look at the odds of winning than the potential winning amount. This keeps you grounded in reality.
To see the likelihood of an acca, you multiply each probability together. Three favourites at 1/2 each: 0.667 × 0.667 × 0.667 = 29.6%. Less than one in three.
A football probability calculator makes these numbers clear. It shows why an ACCA pays more — because the chance of all results landing drops fast.
