The double bet calculator below will work out the return and profit for any double wager you care to make. It doesn’t matter if you bet to win or each way because our calculator can accommodate both. It will also make light work of handling special situations such as Rule 4 deductions and dead heats. Even better, it’s entirely free for you to use whenever you want.
A double bet is one wager on two different events. You can make this type of bet with all of the best online betting sites in the UK. You can bet to win only or – if the events allow – you can make an each way double bet.
With a win-only double, both of your selections must win their respective events for your bet to succeed. For example, if you like to bet on football, you could bet on Liverpool to win one match and on Manchester City to win another match. If both Liverpool and Manchester City win their respective matches, your double bet will also win.
An each-way double is a little different. It can only include events where each way bets are accepted, and it comprises two bets. One is a win double, and the other is a place double. The unit stake on both parts of the bet is always the same, so a £5 each-way double will cost £10. Here you are betting that both of your selections will either win or get placed in their respective events.
For example, in horse racing betting, you could select one horse in each of two different races. If both horses win, both the win and place parts of the each way double will succeed. If one or both of the horses fail to win but still manage to get placed, only the place part of the bet will win. And, of course, if one or both horses fail even to get a place, the each-way double will lose.
Succeeding with a double bet is more difficult than it is with a single bet because both selections need to win or get a place. For that reason, many people wonder why double bets are as popular as they are.
The answer is that a double bet gives you the chance of getting a greater return than you would by splitting the same outlay between two single bets. That’s because, with a double bet, the odds of your selections are multiplied together before being applied to your stake. For this reason, some people refer to a double bet as a double accumulator.
For example, if you were to stake £10 on a win double at odds of 2/1 and 3/1, a winning double would get you a return of £120. If you were to bet two £5 singles instead, the 2/1 bet would return you £15, and the 3/1 bet would return you £20, for a total return of £35.
So, while double bets involve greater risk, they also offer greater potential rewards.
While you can calculate double bet returns manually (as we’ll explain later), using our double bet calculator is much quicker. It’s also a lot easier. All you have to do is follow the few simple steps outlined below:
As we said earlier, it’s perfectly possible to work out a double bet manually. Here we’ll explain what’s involved in doing that. Not because we think it’s a good idea (it’s all too easy to make mistakes) but because it will give you a better understanding of what our double calculator does with the information you provide.
We’ll take you through two calculations. One for a win double and the other for the place part of an each way double.
The win double bet is the easiest to calculate because it’s just one bet at the full published odds. Here’s the formula you need to use to figure out your total return:
(A x B) x S
Where A is the decimal odds of your first selection, B is the decimal odds of your second selection, and S is your stake.
For example, if you have made a £5 double bet on one horse at decimal odds of 2.50 and another at decimal odds of 3.75, your calculation would be:
(2.50 x 3.75) x 5
= 9.375 x 5
= £46.87
The each way double is two bets – one a win double and the other a place double. The win double calculation is as we’ve just described. The place double formula is as follows:
(FA x FB) x S
Where FA is the fraction of the odds of your first selection in decimal format, FB is the fraction of the odds of your second selection in decimal format, and S is your stake.
We’ll now assume that you bet £5 each way on the same two selections at odds of 2.50 and 3.75. We’ll also assume that the each-way place terms are 1/5 the odds in both cases. That would give us decimal odds of 1.30 and 1.55, respectively, and our calculation would be:
(1.30 x 1.55) x 5
= 2.015 x 5
= £10.07
Add the win return of £46.87 to the place return of £10.07 and your total return would be £56.94.
Put the same numbers through our double bet calculator and it would give you a Total Return figure of £56.96. There’s a 2p discrepancy there, and that’s due to the fact that we only calculated to three decimal places. Our EW double calculator is more thorough, and a lot faster!
Previous generations of bettors used pocket calculators (as invented by Sir Clive Sinclair in the early 1970s) to help them work out their bets. Today, online bet calculators are even more convenient. Now that you’ve seen how using our win double calculator is easier than working out double bet returns manually, you might want to look at some of the other betting apps we have available. Visit our Free Bet Calculator page to access our accumulator bet calculator, Lucky 15 calculator and more.
To calculate double bet returns you multiply the odds of your two selections together before multiplying by your stake. An each way double is more complicated, and the easiest way is to use our EW double calculator.
A doubles bet is one bet on two different events. Both of your selections must win (or get a place, if an each way double) for the bet to succeed.
While it isn’t technically a double bet, a Trixie is a multiple bet that covers three selections for three doubles and one treble, making four bets in all.
If you want to cover 5 selections for all possible double combinations, it would take 10 bets. You could also make a Lucky 31 bet, which would cover all of the selections for 5 singles, 10 doubles, 10 trebles, 5 fourfolds and 1 fivefold accumulator.

He originally developed an interest in betting after landing a winning Yankee on his first attempt. He then spent years figuring out how to replicate that success.

However, his preferred approach to winning these days is Dutching, for the simple reason that “It’s a lot easier than landing Yankees.”
