Accumulator

In science an accumulator increases the pressure of compressed nitrogen. The pressure increases or accumulates over the different stages of the process. The net result is that the gas stays at a higher level than at the start of the process by a certain multiple. That is basically the same process for an accumulator in betting.

A betting accumulator begins with a stake unit which multiplies after each winning selection. The running-up potential return depends on the original stake and the odds of each successful outcome However, it is a single line bet so the bet ends with no return if one selection loses. Every selection must win for a winning accumulator.

The most basic bet is a single which involves one selection. The return is based on the stake and the odds of the selection.  A double involves two selections and the winning stake from the first leg runs onto the second leg. Both selections must win for a successful double. A treble takes the bet one stage further because there are three selections.

Any bet with four selections or more is an accumulator, also known as an acca. The return multiples after each winning selection. That means the bet has the potential for a significant return for a small stake. The bet covers a number of events over a period of time so offers bettors a good experience with the potential for plenty of anticipation and excitement.

System bets work in a different way because they bring together three or  more selections in a number of permutations. However, most system bets include an accumulator. One of the most popular system bets is a Yankee. The bet involves four selections in six doubles, four trebles and an accumulator. Each selection does not need to win to generate a return.

An acca bet works on the basis of the stake, odds and the return multiplying after each leg. An accumulator is a single line combination bet because it combines three selections or more in one bet. The start of any accumulator is a single and if the single loses the bet stops. The bet progresses from a single, double, treble to four legs or more and the return accumulates at each stage. You can make your own selections or use accumulator tips.

The most popular sports for accumulators are football and horse racing. However, bookmakers accept accumulators over a range of sports. The best example of a football accumulator is a bet on a number of teams to win their matches in the Premier League. The fixtures can start at the same time or at different times. It is more difficult for bookmakers to control bets over the same time period but they do have the live betting facility to limit their exposure from a winning bet.

Horse racing accumulators are different because races start at different times. They are appealing to recreational bettors because they have an interest over a racing programme. Some bookmakers have restrictions regarding race times but there are checks in place to limit the potential loss. There are many sources of horse racing accumulator tips.

Accumulators are popular with bettors and bookmakers. The bettor has an interest over four or more football matches and they could win a decent amount for a small bet. The interest in these bets creates a demand for football accumulator tips. Conversely, bookmakers can control liabilities and only need one losing selection to avoid a payout. They often have offers related to a footy accumulator to attract more bets, such as acca insurance or acca boost.

William Hill have downloadable apps for Android and iOS devices. The operator also has a browser version as long as the browser is correctly optimised. The apps replicate the desktop computer format and that includes placing a bet accumulator. The process is identical on both platforms so the bet settlement calculation is the same.

Mobile users locate an event through links and menus. The William Hill app is easy to navigate which means an event can be reached with a few taps. Mobile users click on the odds for one event which appears on the Bet Slip. As more selections are added the additional bet options appear on the slip. There is also a field to enter the stake unit and confirm the bet.

When you enter the first selection the only bet option is a single. When you enter the second selection the bet options are two singles and one double. The third selection opens up the opportunity to place three singles, three doubles and a treble. A fourth selection introduces the potential for an accumulator and a system bet that includes an accumulator.

The Bet Slip on the William Hill app shows the potential return from any type of bet. Profit depends on the stake and the combined odds. Mobile users with William Hill can place win or each way bets. An each way accumulator bet is in fact two bets: win and place. The stake is the total of the win and place stake.

However, you should be aware of payout limits on the William Hill app. There can be an upper limit on an accumulator which varies by the sport and the importance of the event. Win limits for each type of bet appear in the William Hill specific and general Terms & Conditions.

The most famous accumulator in horse racing is Frankie’s Magnificent 7. Frankie Dettori rode all seven winners on Champions Day at Ascot in 1996.This bet cost bookmakers a fortune and many went out of business. Combined Starting Price odds were over 25,000/1 and here is how the winnings odds were calculated for this accumulator with seven selections. The return could have been calculated using an odds calculator.

Win Calculation

This example is based on a win £10 accumulator on all of Dettori’s rides on that day.

£10 win at 2/1 = £30

£30 win at 12/1 = £390

£390 win at 10/3 = £1688.70

£1688.70 win at 7/1 = £13,059.60

£13,059.60 win at 7/4 = £37,151.40

£37,151.40 win at 5/4 = £83,590.65

£83,590.65 win at 2/1 = £250,771.95

The combined accumulator odds for the bet are 25,771/1. This calculation is based on the Starting Prices and the return from the accumulator was much bigger at early prices on the day of the meeting.  However, the payout would have exceeded some bookmaker’s payout limits. This bet could have been worked out using an accumulator calculator.

Each way accumulators on horse racing are settled based on place terms which are made up of the number of places and the place proportion of the win odds. Place bet settlement depends on the number of runners and the type of race. The accumulator is a winning bet if each selection finishes in the place payout positions in each race.

Place Calculation

Assuming place terms of one fifth the odds an each way bet on the same seven horses which were placed but did not all win, the accumulator odds would be worked out as follows:

£10 place at 2/5 = £14

£14 place at 12/5 = £47.60

£47.60 place at 10/15 = £79.02

£79.02 place at 7/5 = £189.65

£189.65 place at 7/20 = £256.03

£256.03 at 5/20 = £307.24

£307.24 place at 2/5 = £430.15

The place element of the bet pays 42/1 so if just one of the seven horses had finished second and not first the payout would have been relatively miniscule compared to the win payout. You could do this calculation manually or use a profit accumulator calculator.

The two most popular sports for accumulators are football and horse racing. Bets can be placed in singles, doubles and trebles. The bet becomes an accumulator when there are four selections or more. Each leg must be successful for a winning accumulator and the return is based on the stake and combined odds. However, in some cases one or more selection does not take part.

There could be a non-runner in a horse race or a postponed football match in a football betting accumulator. This means these selections cannot contribute to the multiplied odds. However, they did not lose so bettors do not lose their stake. However, when there is a non-runner or abandoned football match there are no odds that can form part of the calculation.

Bookmakers settle bets on the odds of the selections that took place in the horse race or football match and any other sporting events in an accumulator. That means an accumulate with four selections and one non-runner becomes a treble. The odds accumulate in three stages rather than four. This rule applies regardless of the number of selections and the number of non-runners.
