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.

What is a Double Bet?

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.

Why Make a Double Bet?

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.

How to Use Our Double Bet Calculator

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:

  1. Select Double Bet Mode

    Look at the top of the calculator, and you’ll see that it can operate in several different modes. Start by tapping the Doubles button to activate the double bet mode. Then, if you want to use it as an each way double bet calculator, go to the Each Way selector and choose Yes.
  2. Enter Your Stake

    Use the Unit Stake field to enter your stake for the bet. For example, if you want to calculate a £10 each way bet, you would enter 10. Your Total Stake for the bet would then be shown as £20 at the bottom of the calculator.
  3. Choose the Odds Format

    This bet calculator can accept odds in any of the three main formats used by online bookmakers. Use the Odds Format selector to choose from fractional, decimal or American odds according to your preference.
  4. Enter the Odds

    Next, enter the odds for your selections. When using fractional odds, you’ll see two cells. One is for the left side of the odds, and the other is for the right side of the odds. Just one cell will be shown by the doubles calculator for decimal or American odds.
  5. Select the Place Term

    If you are using our app as an each way double calculator, you will need to select the Place Term for each of your selections. You can take this information directly from the betting market. For example, if you have made a bet in a market that states, ‘EW: 1/5 Odds 4 Places’ you would select 1/5 in the Place Term menu.
  6. Select the Result

    Now select the result for each of your selections from the Result menu. The options here are Won, Placed, Dead Heat, Lost and Void, all of which our double betting calculator can take care of automatically. If you have a selection that is subject to a Rule 4 deduction, the Rule 4 menu will let you select the size of that deduction.
  7. Calculate

    Having entered the simple details outlined previously, all that’s left for you to do is tap the Calculate button. The doubles bet calculator will then crunch the numbers provided and display your Total Return and Total Profit – all in the blink of an eye. 

How to Work Out a Double Bet Manually

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.

Win Double Calculation

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

Each Way Double Calculation

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!

Calculators for Other Bets

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.
