What is a Treble Bet?

A treble bet allows you to predict the outcome of three different events in a single wager. It’s a bet that can be made at all of the best betting sites in the UK and on all sports. Win trebles are always possible, and if you bet in markets that pay for places, you can also place each-way trebles. Let’s take a moment to explain the difference.

When you make a win treble bet, you will only get a return if all three of your selections win. Those who enjoy betting on tennis, for example, might predict the winner of three different matches. All three players must win those matches for the bet to succeed.

With an each-way treble, you are making two bets. One is a win-only treble as just described and the other is a place-only treble. The latter will give you a return as long as each of your three selections gets a place.

For example, when betting on horse racing, you might try to predict the winner in each of three different races. If all three horses win, both parts of the each-way treble will succeed. If one or more of your selections fail to win but still get a place, only the place part of the each-way treble would succeed. And if one or more horses don’t even place, the whole bet will lose.

Why Make a Treble Accumulator Bet?

A treble is actually an accumulator bet. That means the odds of each selection are multiplied together and then applied to your stake when the bet is settled. A winning treble would therefore win you a lot more than three winning singles.

To illustrate, let’s imagine that you want to bet on three horses at odds of 1/1, 2/1 and 5/2. If you were to bet £5 on each as win singles, they would return £10, £15, and £17.50, respectively. That’s a total return of £42.50 for a total outlay of £15, which is a profit of £27.50.

Now let’s consider what would happen if you were to bet on all three of those same horses in a £5 treble. That trebles bet would give you a total return of £105 for a £5 outlay, which is a profit of £100. And if you were to bet £15 on the treble, you get back £315!

So, to return to the question of why make a treble, the answer is profit potential. A treble involves more risk than betting singles, but you’ll make a lot more profit when you succeed (see the value behind multiples in this study).

How to Use Our Treble Bet Calculator

While a treble accumulator isn’t the most difficult bet to work out manually, it’s always quicker to use an automated trebles calculator. Our free treble bet calculator needs just a few simple details about your wager to tell you your expected return in a split second. Here’s how to use it:

  1. Activate Treble Bet Mode

    Start by tapping the Trebles button at the very top of the app. That will set it up as a win treble bet calculator. If you’d like it to function as an each way treble bet calculator then simply choose Yes under the Each Way selector.
  2. Select the Odds Format

    You can enter odds for your bet in any of the three formats that are in common use. Use the pulldown Odds Format selector to choose fractional, decimal, or American odds. We would recommend using the same format as the bookmaker you’re betting with.
  3. Define the Place Term

    When using this app as an each way treble calculator you will see a Place Term menu. You should use that to select the fraction of the odds that you will get for a place. In horse racing, this is most often 1/4 or 1/5.
  4. Enter Your Stake

    Now enter the amount of money that you have bet on the treble. For example, if you have bet £5 each way, enter 5. You’ll see that the EW treble bet calculator automatically doubles that number to show the Total Stake of 10.
  5. Input the Odds

    The next item of information that our treble odds calculator needs is the price that you got for each of your selections. Enter the odds into the Odds field in the format you selected earlier. Note that there are two fields for fractional odds – one for the left side of the odds and one for the right side of the odds.
  6. Select the Result

    You should now select the result for each of your three selections. This is done via the Result pulldown menu, where you can choose Won, Placed, Dead Heat, Lost or Void. If any of your selections are subject to a Rule 4 deduction, choose the value of the deduction using the Rule 4 menu. 
  7. Calculate

    Finally, hit the Calculate button to set the bet treble calculator into action. Our app will then process all of the information you have provided and work out the Total Return of your bet. This will be displayed at the bottom of the app, along with the Total Profit figure.

How to Work Out a Treble Bet

You’ve just seen how easy it is to use our treble bet calculator. It’s also very quick, with all of the numbers being crunched for you in a fraction of a second. But what if you want to work out the expected returns of a treble without a treble calculator? In that case, you’ll need to set aside some time and work through the numbers manually. Here are the formulas that you’ll need:

Treble Win Bet Calculation

The easiest type of treble to calculate is the win-only, and the formula is as follows:

(A x B x C) x S

Where A, B, and C are the odds (in decimal format) of your three selections and S is your stake.

For example, let’s say that you like to bet on darts and you’ve put a £5 treble on three players at odds of 2.00, 1.80 and 1.90. In that case, you would calculate:

(2.00 x 1.80 x 1.90) x 5

= 6.84 x 5

= £34.20

Treble Each Way Bet Calculation

You’ll recall that an each-way bet is really two bets, so it needs to be calculated as such. For the win part, you should use the win bet formula that we discussed a moment ago. For the each-way part, the formula to use is:

(FA x FB x FC) x S

Where FA, FB and FC are the fractions of the odds obtained, in decimal format, and S is your stake. 

For example, we’ll now imagine that you prefer to bet on greyhound racing. We’ll say that you’ve bet £5 each way on three dogs in a treble at odds of 4.0, 5.0 and 6.0 and that the place terms are 1/4 the odds. After applying that fraction to the odds you took, you get FA, FB and FC figures of 1.75, 2.00 and 2.25. Your treble bet calculation would be:

(1.75 x 2.00 x 2.25) x 5

= 7.875 x 5 

= £39.37

This is how much your each-way treble bet would return in total if one or more dogs only manage to get a place. If they all win, you’d get the return from the win part as well, so don’t forget to add that.

As you can see, each-way bets are more complicated to figure out. And both types of bets can be further complicated by dead heats and Rule 4 deductions. For those reasons, we’d always recommend using a treble each way calculator rather than working things out manually.
