Accumulator bets are a popular way to combine several selections into one wager. They can look a bit technical at first, but once you understand how the odds link together, the idea clicks into place.
This guide breaks down what an accumulator is, how the odds and payouts are worked out, and what types you might see. You’ll also find a worked example, an explanation of cash out, key rules to know, and a balanced look at the pros and cons.

What Is An Accumulator Bet?
An accumulator bet, sometimes called an “acca”, is a single bet that links two or more selections. Every selection has to win for the bet to pay out. If one leg fails, the whole accumulator loses.
For example, someone might build an accumulator across several football matches, picking a team to win in each one. All those results must be correct for a return.
The appeal is that the odds from each selection are multiplied, which means the potential return can be higher than backing each pick separately. The trade-off is that adding selections makes a successful outcome less likely, so it’s sensible to keep stakes affordable.
How Do Accumulator Odds Work?
Accumulator odds are formed by multiplying the odds of each individual selection to create one combined figure.
If a player chooses three teams at 2/1, 3/1, and 4/1, the combined fractional odds are 2 x 3 x 4, which equals 24/1. Using decimal odds works the same way: multiply the decimal prices together for the final number.
With each extra selection, the overall odds rise because more outcomes are included. Remember that every selection must win for the accumulator to return anything, so adding legs increases the risk alongside the potential return.
How Are Accumulator Payouts Calculated?
Understanding how payouts work is key for anyone considering an accumulator bet. The calculation depends on the type of odds used, either decimal or fractional.
Step-By-Step Calculation With Decimal Odds
With decimal odds, multiply the odds for each selection together, then multiply by the stake. The result is the total return, including both the original stake and any winnings.
For example, with a £5 stake on three selections at 2.00, 3.00, and 4.00:
Multiply 2.00 x 3.00 x 4.00 = 24.00
Then multiply 24.00 x £5 = £120 total payout
Step-By-Step Calculation With Fractional Odds
With fractional odds, the process builds the return through each leg in turn. Start with the stake and apply each price in sequence.
For example, with a £5 stake on three selections at 1/1, 2/1, and 3/1:
First, £5 x 1/1 = £5 winnings + £5 stake = £10 total
Next, £10 x 2/1 = £20 winnings + £10 stake = £30 total
Finally, £30 x 3/1 = £90 winnings + £30 stake = £120 total payout
Worked Example: Three-Selection Accumulator
To see it in action, here is a simple three-selection football accumulator.
Imagine a player chooses three teams to win:
Team A at decimal odds of 2.00
Team B at decimal odds of 3.00
Team C at decimal odds of 4.00
If the player stakes £5 on all three as one accumulator, the calculation is:
Multiply the odds together: 2.00 x 3.00 x 4.00 = 24.00
Then, £5 x 24.00 = £120 total return
That total includes the initial stake. All three teams must win for the accumulator to pay out. If even one does not, the entire accumulator is settled as a loss.
What Types Of Accumulators Are There?
There are several types of accumulator bets, each defined by how many selections are linked and how they’re combined on the slip.
A standard accumulator is often described by the number of legs: a double (2 selections), treble (3), four-fold (4), or larger five-folds and beyond. Each one is a single bet that needs every leg to win.
There are also system bets such as a Yankee, Lucky 15, or Heinz. These combine multiple smaller accumulators in one overall wager. Because they cover many combinations, some returns may still be possible even if not every selection wins. The trade-off is a higher total stake, as several bets are placed at once.
Each-way accumulators split the stake between the win and place parts, most often in sports like horse racing. This can provide a return if selections place without winning, depending on the place terms offered.
What Is An Each-Way Accumulator?
An each-way accumulator covers two outcomes for each selection: one for winning and one for placing (for example, finishing in the top three or four, depending on the event and terms).
The stake is doubled because it is split equally between the win and the place parts. In effect, you are placing two accumulators: one on all selections to win, and one on all selections to place. If a selection only places, the place part may still return a payout based on the place terms.
All selections must qualify on the relevant part for that side of the bet to pay out fully. Check the place terms before placing an each-way accumulator, as the number of places and the reduction applied to odds can vary by event.
A natural next question is what happens if you want to settle early rather than wait for the final result, which brings us to cash out.
Can You Cash Out An Accumulator Bet?
Cashing out an accumulator lets a player settle the bet before all selections have finished. The amount offered reflects how the completed legs have performed and the current status of the remaining ones. It is usually less than the full potential return but can secure a payout without waiting for the final result.
Not every market or event is eligible for cash out, and availability can change while matches are in play. Some accumulators will not support cash out at all. It’s worth checking the terms on the platform being used and deciding in advance what approach suits your budget.
Common Accumulator Rules And Terms
A few standard rules and terms will help make sense of how accumulators are settled:
- Selections: Each separate outcome chosen in an accumulator is a selection. Every selection must be correct for a standard accumulator to win.
- Stake: The amount placed on the accumulator. If the bet wins, the stake is included in the total return.
- Void Selections: If a selection is void, for example, due to a cancelled match, it is usually removed from the accumulator. The bet continues with one fewer leg and the payout is adjusted.
- Dead Heat: If there is a tie in events like horse racing, a dead heat rule may apply. The payout for the affected selection is typically divided by the number of participants who tied.
- Each-Way: An option that splits the stake between the win and place parts, most common in racing. Place terms and reductions vary and are set in advance.
- Settlement: How and when the bet is paid out, usually shortly after the final event is completed. Exact timings and processes can differ by operator, so it’s always worth reading the terms.
How Much Can You Win From An Accumulator Bet?
Returns depend on three main factors: the odds of each selection, the total number of selections, and the size of the stake. Because the odds are multiplied, adding legs increases the possible payout.
For example, a £5 accumulator on three football teams priced at a combined 24.00 would return £120 in total, including the original stake. The exact figure always depends on the selections and prices chosen.
Most operators set maximum payout limits for accumulators, and these are listed in their terms and conditions. It is sensible to check those limits and to set a personal budget that you are comfortable with.
Pros And Cons Of Accumulator Bets
Accumulator bets have strong points and drawbacks that are worth weighing up.
Pros:
- They offer the chance of a higher potential return from a relatively small stake because the odds are multiplied.
- They also let people bring different matches, markets, or sports into one bet, which can be a tidy way to follow a day’s action.
Cons:
- Every selection needs to win for a standard accumulator to pay out, so adding more legs reduces the chance of success.
- Complex system bets can also increase the total stake quickly, as multiple bets are placed at once.
