What is an Accumulator Calculator?
An accumulator calculator (or acca calculator) is a free betting tool that calculates potential returns for multi-leg bets. Popular in the UK and Ireland for football betting, accumulators combine multiple selections into one bet where all outcomes must win for a payout.
Also known as parlays in the US, accumulators multiply the odds of each selection together, creating potentially large returns from small stakes. Our calculator handles up to 20 selections and works with decimal, fractional, and American odds formats to suit bettors worldwide.
How Accumulator Calculations Work
The accumulator calculation is straightforward but can become complex with many selections:
Accumulator Formula
Total Odds = Leg 1 × Leg 2 × Leg 3 × ... × Leg n
Total Return = Stake × Total Odds
Profit = Total Return - Stake
Example: £10 on 2.00, 1.50, 3.00, 1.80
Total Odds = 2.00 × 1.50 × 3.00 × 1.80 = 16.20
Total Return = £10 × 16.20 = £162.00
Profit = £162.00 - £10 = £152.00
Types of Accumulators
| Selections | Name | Example Odds | £10 Returns |
|---|---|---|---|
| 2 | Double | 2.00 × 2.00 = 4.00 | £40.00 |
| 3 | Treble | 2.00 × 2.00 × 2.00 = 8.00 | £80.00 |
| 4 | Four-fold | 2.00 × 2.00 × 2.00 × 2.00 = 16.00 | £160.00 |
| 5+ | [Number]-fold | Continues multiplying | Exponential growth |

Frequently Asked Questions
What is an accumulator calculator?
An accumulator calculator is a free betting tool that calculates potential returns for multi-leg bets (accas). It multiplies the odds of all selections together to show total odds and potential profit. Popular for football betting, it instantly shows how much you could win if all selections are successful.
How do you calculate accumulator odds?
To calculate accumulator odds: Convert all selections to decimal odds, multiply them together, then multiply by your stake for total return. For example, three selections at 2.00, 1.50, and 3.00 decimal odds = 2.00 × 1.50 × 3.00 = 9.00 total odds. A £10 stake returns £90.
What happens if one leg of an accumulator loses?
If any single selection in an accumulator loses, the entire bet loses. All selections must win for an accumulator to pay out. This all-or-nothing nature is why accumulators offer such high potential returns but are also much riskier than single bets.
What's the difference between an accumulator and a parlay?
Accumulator and parlay are different names for the same bet type. 'Accumulator' or 'acca' is used in the UK and Ireland, while 'parlay' is the American term. Both refer to combining multiple selections into one bet where all must win for a payout.
How many selections should I include in an accumulator?
Most successful accumulator bettors recommend 4-6 selections as optimal. This balances potential returns with realistic winning chances. While you can include up to 20 selections, remember that each additional leg significantly reduces your chances of winning.
