Accumulator Calculator: Maximize Wins with Our Free Tool

Last Updated on 23/05/2024

With our accumulator calculator, you can calculate the overall odds and total payout for any accumulator bet containing two or more selections.

For an accumulator bet to win, all of your selections have to be correct - if you get one wrong, then the whole wager is lost. However, with greater risk, come bigger potential rewards, which is why the expected return and profit are significantly more than you would get by backing each selection individually.

How to use the accumulator bet calculator

Using our accumulator bet calculator is simplicity itself. First, you need to decide on the number of selections you want to include. Then enter the odds for each of your selections and your stake amount.

Once that’s done, click the ‘Calculate’ button and the calculator will display your expected return and profit, plus the implied probability of your accumulator bet winning.

The more selections and the higher the odds, the more you stand to win. However, your probability of winning will decrease substantially the more selections you add. Nevertheless,  acca bets are a popular choice for bettors when faced with a number of short-priced favorites.

Accumulator betting explained

An accumulator bet is a type of combo bet that involves bundling multiple selections together to create one single wager. When using the acca calculator, the odds are multiplied together,then multiplied by your stake,  which results in a much larger potential payout than you would get were you to bet on each selection individually.

However, all of your bets need to win for your accumulator bet to win, which reduces the win probability and increases the risk. To get an idea of how much of your total bankroll you should bet on an accumulator, you can use our Kelly Criterion calculator in combination with this one.

How the betting works with an accumulator

With an accumulator bet, a single stake covers all of the selections. To refer to the example used in our accumulator calculator above, you would be betting $10 at overall odds of +882.

Accumulator bets vs parlays

Accumulator bets and parlays are basically interchangeable terms, with no distinct differences between them. Accumulator or “acca” is generally favored across the pond in the UK and Ireland, meanwhile, parlay is the more common terminology for a multi-selection bet here in the US.

However, some betting sites make fairly loose distinctions. For example, any combo bet with two or more selections is referred to as a parlay, but the same sportsbook might specifically refer to a parlay with four selections as a “fourfold accumulator”. It’s just something to be aware of to avoid confusion.

Accumulator bet vs system bets

However, a much clearer distinction can be made between accumulators and system bets. As we explained in the example using our accumulator calculator earlier, all of your selections need to win for your acca to payout.

However, with a system bet, you can still receive a payout if one or two of your selections win, depending on the number of selections included in the bet. As a result, the risk is lower with a system bet when compared to an acca, but the odds are shorter, and the expected payout is smaller.

Why the accumulator odds calculator is useful

Below we have highlighted a few key points of why this calculator is particularly useful, regardless of your sports betting experience:

Quick and easy

First and foremost, the accumulator calculator is an intelligently designed tool that is quick and easy to use for experienced or first-time bettors.

Instant results

Once you have entered the required information, you get instant outputs to facilitate quick decision-making.

Full transparency

The parlay and accumulator bet slips at most sportsbooks only show the potential payout and profit. They often hide key factors like the overall odds and implied probability. Our bet accumulator calculator is fully transparent and tells you everything you need to know.

Informed decision-making

Once you have the results from our accumulator bet calculator, you can make smart and informed betting decisions based on the outputs displayed. 

Flexibility

You can play around with this calculator and adjust your acca by adding or removing selections and/or changing the overall stake.

Calculate accumulator - Conclusion

As a final reminder, an accumulator bet allows you to combine two or more selections into a single wager. The odds for all selections are multiplied, which gives you a much larger potential payout. However, the win probability is lower due to the fact that just one selection losing means that the entire bet is lost.

With our accumulator calculator, not only can you establish your potential return and profit, you can also see the overall odds for the bet and the implied probability of success. At the end of the day, it gives you everything that you need to make a fair assessment and place smarter acca bets.

Accumulator calculator FAQ

🤔 How do you calculate an accumulator bet?

To get the overall odds for your accumulator bet, you need to multiply the odds for each selection together. From there you can use the combined odds to work out the payout based on your stake. Though it’s easy in theory, it’s time-consuming in practice, which is why we recommend that you use our accumulator bet calculator here at PromoGuy.us.

🔥 Is an accumulator bet profitable?

Though it varies depending on the number of selections that you make and the odds for each selection, accumulator bets have a high predicted payout. However, as all of your selections need to win for you to get the payout, the win probability is low and the risk is high.

📌 How many bets do you need for an accumulator bet?

The definitions are slightly different in each country, but in general, four or more bets are considered to be an accumulator. Two selections are often called a double, while three is a treble - though both of these work the same way as an accumulator, by multiplying the odds for each selection.
