Accumulator Betting

Although most people are familiar with the simple back bet (where you bet on a particular event taking place (for example Manchester City to win against Barcelona), the accumulator bet is a more complex form of betting which usually requires some explanation.

Frequently used for a racing bet, an accumulator, or “acca” as it is often called, can also work well for football betting or any other form of sports betting where there are going to be a number of consecutive results within a fairly short space of time.

Here we take a look at what an accumulator bet is, how and when you may place an accumulator bet and what the potential benefits of accumulator betting may be.

What Is An Accumulator Bet?

An accumulator bet is a bet which is placed on a number of different events. If all the bets in the accumulator are predicted correctly, they total win is a return which is far greater than if the bets had been placed separately. Unfortunately, if even one of the bets in the accumulator is lost, the entire stake is forfeit, even if the other events in the accumulator turn out as predicted.

It's possible to place accumulators which consist of a very high number of bets which can represent a huge return, even if a relatively small amount is wagered. The key thing to remember with an accumulator is that whilst the possible return can be very high, it only takes one of the back bets included in the accumulator to lose and the entire stake is forfeit. You will win nothing.

How Are Accumulator Bet Odds Calculated?

The odds on an accumulator bet being realised are far greater than the sum of the individual back bets which form the accumulator. Accumulator bets are calculated by:

  1. Converting the fractional odds for each event in the accumulator into decimal odds, if they're not already. This is done by dividing the first figure by the second one and then adding one. For example, odds of 4/1 convert to decimal odds of 5. Fractional odds of 11/4 convert to 3.75.

  2. Multiplying the decimal odds of each back bet in the accumulator together. For example, if the odds of the four bets in the accumulator are 5.0, 3.75, 2.8 and 3.8, the accumulator odds would be (5.0 x 3.75 x 2.6 x 3.8) = 185.25.

What this means in money terms, is that if you put a £10 bet on this accumulator and all four events returned in your favour, you would be in receipt of 185.25 x 10 = £1852.50. With such a generous return on the initial stake, it's clear why accumulator bets are such a popular option, particularly with seasoned punters who feel like they can predict the outcome of sporting events with good accuracy.

How Do I Put On An Accumulator Bet?

Placing an accumulator bet online is simple here at When you start adding bets to your bet slip, you will see an option at the top of the slip called ‘Acca’. Simply selecting this option will convert all your bets into an accumulator. You can switch back to single bets at any time by selecting the ‘single’ option, where each bet uses its own stake and offers a return that’s independent of other bets.

When creating an acca, your betting slip will calculate your accumulator odds as you add more selections to your card. When you've finished making your selections, you place your stake in exactly the same way as you would for a single bet.

What Sports Can I Place An Accumulator Bet On?

Most sports are suitable for accumulator betting, provided the outcome of one event doesn't influence the outcome of the next in such a way as betting on both would be impractical. As mentioned previously, some of the most popular are horse racing betting and football betting accumulators, but team sports, league sports and tournaments are all suitable for accas.

Accas can be placed before the first event on which you're betting commences, or be placed during events (in-play betting). If you're new to betting (or accas), it's normally best to start with placing bets before events, moving on to in-play betting when you have a little more experience.

What Do I Need To Be Aware Of When Placing An Accumulator Bet?

Accas have the potential to deliver a significant return on investment and, as such, are a popular choice. Because the consequences of losing even one bet are severe, it's vital to check and double-check that you have recorded your preferred selections accurately and clearly. Remember to read the rules when it comes to accumulator bets and situations such as no-score draws, withdrawn horses or cancelled matches. Accas can consist of bets from the same sport, or potentially contain bets from two or more differing sports.

With a little practice, it's usually fairly straight-forward to get the hang of accumulator bets, providing added interest to your sports betting experience alongside single back bets or other betting combinations.
