An accumulator calculator (also called an acca calculator or parlay calculator) helps you calculate your combined odds, potential return and profit from multiple selections.
Instead of manually multiplying odds, the calculator gives you the combined figures instantly – making it useful for anyone placing accumulator bets on football, horse racing or other sports.

Enter your stake and decimal odds to calculate the combined accumulator odds, potential return and potential profit. Adjust the selections to see how different odds affect the overall calculation.
Calculate Your Acca
What Is an Accumulator Bet?
An accumulator (acca) combines multiple selections into a single bet.
- All selections must win for the accumulator to pay out
- The decimal odds are multiplied together
- Potential returns increase as more selections are added, but so does the risk of losing the entire stake
In the US, an accumulator is commonly known as a parlay bet.
How an Accumulator Calculator Works
An accumulator calculator automatically:
- Multiplies your decimal odds together to calculate the total accumulator odds
- Calculates your potential return based on your stake
- Shows your potential profit after subtracting the original stake
This lets you see how adding or removing selections changes the potential return of an accumulator.
Formula (Using Decimal Odds)
- Total Odds = Odds 1 × Odds 2 × Odds 3 × …
- Total Return = Stake × Total Odds
- Profit = Total Return − Stake
Example Acca Calculation
Stake: £10
Odds: 2.00, 1.50, 3.00, 1.80
- Total Odds = 16.20
- Total Return = £162
- Profit = £152
Because accumulator odds are multiplied together, changing one selection can have a significant effect on the overall potential return. An accumulator calculator makes these calculations easier to check.
Accumulator Bet Types Explained
Accumulator names generally refer to the number of selections included in the bet:
- Double (2 selections) - Two odds are multiplied together
- Treble (3 selections) - Three odds are multiplied together
- Four-fold (4 selections) - Four odds are multiplied together
- Five-fold (5 selections) - Five odds are multiplied together
The more selections you add, the more the combined odds can increase, but one losing selection will generally cause the entire accumulator to lose.
How to Use an Accumulator Calculator
- Enter your stake - Add the amount you want to use for the accumulator.
- Enter your selections - Add the decimal odds for each selection, one per line.
- Calculate your acca - The calculator multiplies the odds together to determine the combined odds.
- Review the results - Check your total odds, potential return and potential profit.

More advanced betting features, such as each-way calculations, acca boosts, insurance, cash-out offers and void-selection rules, depend on the sportsbook and the specific calculator being used. Always check the applicable sportsbook terms for how these features are handled.
Accumulator Strategies
There is no fixed number of selections that provides the ideal balance between risk and potential return. Adding more selections increases the combined odds, but also means more individual outcomes must be correct for the accumulator to win.
1. Keep the Number of Selections Manageable
Consider how many selections you can reasonably research and understand rather than adding legs simply to increase the potential return.
Every additional selection creates another outcome that must be correct for the accumulator to win.
2. Compare Odds and Market Prices
Rather than choosing selections based solely on short odds or favourites, compare the available prices and consider the probability implied by those odds.
Different sportsbooks may offer different prices on the same market, although the market and settlement conditions should be checked before comparing them.

3. Consider Different Market Types
An accumulator can combine selections from different markets, depending on what the sportsbook offers.
Examples include:
- Match result
- Both Teams to Score (BTTS)
- Over/Under goals
- Player markets
- Handicap markets
Different markets have different settlement rules, so check the applicable terms before placing an accumulator.
4. Consider Cross-Sport Accumulators
Some sportsbooks allow selections from different sports to be combined in one accumulator.
Examples can include football, tennis and basketball.
Combining different sports does not reduce the inherent risk of an accumulator. Each selection still needs to meet its applicable settlement conditions for the bet to win.

Frequently Asked Questions
What is an accumulator calculator?
An accumulator calculator combines multiple selections, calculates the total decimal odds, and shows the potential return and profit based on your stake.
What happens if one bet loses?
In a standard accumulator, all selections must win for the bet to pay out. If one selection loses, the entire accumulator loses.
What does "void" mean in an accumulator?
A void selection is generally removed from the accumulator, with the remaining selections recalculated according to the sportsbook's rules. Exact treatment can vary between operators and markets.
How many selections should I include in an accumulator?
There is no fixed number that makes an accumulator suitable for every bettor or situation. Adding more selections increases the combined odds but also means more outcomes must be correct for the accumulator to win.
Can I combine different sports in an accumulator?
Many sportsbooks allow selections from different sports to be combined in one accumulator, although availability depends on the operator, markets and applicable rules.
Are accumulator bets profitable?
A winning accumulator can return more than the original stake, depending on the combined odds and stake. However, the risk increases as more selections are added because every selection must be successful for a standard accumulator to win. No accumulator strategy can guarantee a profit.
