What Is An Accumulator?

All about Accas and Accumulators

A few questions may have lead you to this page, so we’ll try to answer the following. You can use the links below to skip to each question if it’s relevant to you.

But to start you off, Acca & Accumulator are the same thing.

What is an acca?

An acca (or accumulator) is a multiple bet whereby single bets are combined into 1 long bet and the winning pot accumulates as each event wins. An example would be 5 football matches, and you chose the results of each match.

An acca is a ‘multiple’, which means two or more bets combined and is similar to a double (2 selections) and a treble (3 selections). After a treble you are into what we call accas and they are distinguished by how many ‘fold’ you select: a 4 fold acca (4 selections), a 5 fold (5 selections)… and so on!

How do you place an acca?

If you are online betting, to place an acca select multiple single bets and build them up onto your virtual betting slip. If the betting site allows an acca on the events you have selected, then acca or accumulator will appear as an option on the slip.

Here is a screenshot from a betfair Accumulator showing a “5 football matches” example i.e a 5 fold.


In the example we have chosen 5 games and picked the outcomes for those 5 matches. You can see the betslip in our example has 5 matches listed as single bets. Below those selections is an item called 5 Fold (x1). which is our 5 events merged into 1 accumulator bet. An acca is one bet that requires all your selections to match what you have picked. If 1 result is wrong then the entire acca is lost. In the example you will place you stake has 1 bet so a £10 acca, requires you to spend only £10. (Some more complicated multiples required more than 1 bet)

What is cashout?

Cashout is a facility that SOME bookies offer, which is a way for them to buy back the acca during the running of the bet if it looks like it might come in. So let’s say your 5 football matches all kick off at 3pm on a saturday afternoon, at half time all your results look good and you just can’t wait to see it through. If cashout is on offer, your betting site ‘may’ offer you a lower price, to basically encourage you to give up your bet. It may go onto win (your loss), it may go on to lose (Woohoo – you beat the bookie)

What is acca insurance?

If your 5 fold or more acca loses by one selection, you get your money back generally as a free bet bonus (not as withdrawable cash). Some bookies may refund your stake as cash, but safely assume that for the most part, bookie refunds come in the form of a free bet to the value of your original stake. Acca insurance like common domestic insurance is not a actually paid for premium service. Its simply a condition that applies to your acca if you have selected more than 5 events and this number is based on the majority of bookies offering this feature. If only one of those selections loses, the insurance kicks in and the bet is refunded. Acca insurance is not guaranteed, it is commonly offered as a bonus feature and may even be limited to select set of markets i.e Football.

Acca Edge

Acca edge is similar to acca insurance but is unique to betfair and you must manually add it to your bet slip for it to apply to your accumulator

‘Acca Edge’ is replacing the ‘Acca Insurance’ and with that we are now offering the most competitive form of insurance in the industry:

  • Refunding as cash when the competitors refund as free bets
  • Receive your refund straight away when the last leg is settled, not having to wait around to the next day to receive your payment
  • Acca Edge applies to trebles and above, not five folds and above that other competitors offer – cannot get this anywhere else
  • We offer this across all sports, we can mix any selections that you want – cannot get this anywhere else
  • We don’t have any max refunds (general max refund in the industry is £25)
  • There is no minimum odds you have to sign up to, once you have three selections or above, Acca Edge kicks in.

How is the reduction in odds calculated?
The reduction in odds is calculated by us to offer the true price the bet would be, if one of the selections failed to win. So in a nutshell, the probability of one of the selection not winning.

  • there is a dead heat:
    Acca Edge gets voided. Bet reverts to the price before Acca Edge was applied.
  • you use Cash Out:
    Bet gets settled for the Cash Out amount and any further Acca Edge payment is void. Chance of Acca Edge applying is factored into Cash Out offer.
  • BOG Edge (Best Odds Guaranteed):
    Acca Edge and BOG work in tandem. If the bet wins the return is based off the new BOG prices, and the Acca Edge reduction % still applies (which is the same as it was at bet placement).
    •     4-fold with all 4 legs at 2/1
    •     Acca Edge used, which reduces the multiple price from 80/1 to 72/1 (9.9% reduction)
    •     Bet wins and BOG applies for 1 horse, taking it to 3/1
    •     Bet pays out at 96/1 (9.9% reduction to the BOG multiple odds of 107/1)
  • Horseracing rule 4 deduction Edge:
    Acca Edge and Rule 4 work in tandem. If the bet wins the return is subject to the rule 4 and also the Acca Edge % (which is the same as it was at bet placement)

How do I calculate accumulator winnings?

An acca is calculated through the accumulation of winnings upon the completion of each stake. So let’s assume all selection are at odds of evens i.e 1/1 matching your stake when it wins. So you have 5 selections all at even odds 1/1 and you place £10 on the acca. The winnings grow (accumulate) as if each win generates a new stake to go on the next selection in the acca.

  • Selection 1 opens with £10 at evens, it wins and therefore you now have £20
  • Selection 2 now has £20 “going on it” at 1/1 and that wins, you now have £40
  • Selection 3 turns £40 into £80
  • Selection 4 turns £80 into £160
  • Selection 5 the final event has accumulated £160, which equals £320 if it wins at 1/1

You can easily see how much you might win using an acca culculator or betting calculator like this one at ladborkes http://www.ladbrokes.com/betCalculator/betCalc.html or this one at Oddschecker https://www.oddschecker.com/betting-tools/bet-calculator

What are the best sites for football accas?

Generally the top sportsbooks all offer accumulators within the multiples section of the betslip. And based on the principles that its just a simple calculation that determines the outcome, no betting site should really be any better than the others. What makes them stand apart are the additional bonus features, like cashout, acca insurance, partial cashout even (when you cash out a percentage of the ‘buyback’ offer and leave some in the pot). But here are couple of recommendations nonetheless.

  • Betvictor claim to have the best odds for football
  • PaddyPower have acca insurance & cashout
  • Bet365 have cashout & partial cashout
  • Skybet are shit! Cashout goes down just at those crucial times!!!!!!

Can I place an acca on any sport or any market?

You can build your acca based mainly on single events, like a football match, a horse race, sometimes even a market within a football match like a team to win to nil or both teams to score Yes/No. Most gamblers generally keep their accas to the same sport and the same markets like football Win

You can’t combine events from the same match in an acca like both teams to score, first goal score, number of yellows – although these are often available as ‘special bets’ using a bookies request odds features.

When places are up for grabs i.e horse racing 1st to 3rd, you can make an each way acca by selecting the e/w tick box if available, this doubles your stake as its 2 bets. So a £10 acca e/w, requires a £20 wager. If 1 event places in that bet (but does not win), your win acca has lost and you are then only playing for each-way money, even if all the other horses win.

Key points:

  • An acca is one bet and all results have to match what you’ve picked, if one loses the whole acca loses
  • As your bets win, the total winnings at the end increase based on the multiplication of each event
  • Some sportsbook operators let you cash out during the running of an acca before it closes
  • 2 selections make a double, 3 selections is a treble, more than 3 is an acca starting from 4 fold
  • Acca insurance offers a refund on accumulators of 5 or more selections
