Accumulator Calculator
By the TheyShoot editorial team. Updated
Add each leg's odds to see your acca's combined price and return. An accumulator's odds are every leg's decimal odds multiplied together, so four legs at 2.00, 1.80, 2.50 and 1.50 make a 13.50 acca: a £5 stake returns £67.50.

Returns ignore bonuses, Rule 4 deductions and dead heats. Check your bookmaker's settlement rules.
How to use the accumulator calculator
- Enter your stake and the odds of each leg. Add or remove legs as you need, up to 20.
- Mark each leg as won, lost or void.
- Read your total return and profit. If any leg loses, the acca returns nothing.
How acca odds are calculated
Acca return = stake × odds of leg 1 × odds of leg 2 × … × odds of the last leg, using decimal odds. A void leg counts as 1.00, so it is removed and the acca becomes one leg shorter.
Worked example
A £5 four-fold at 2.00, 1.80, 2.50 and 1.50 has combined odds of 2.00 × 1.80 × 2.50 × 1.50 = 13.50. If all four win, it returns £67.50 for a £62.50 profit. If the third match is postponed and made void, the odds become 2.00 × 1.80 × 1.50 = 5.40, and the bet returns £27.00.

FAQs
What happens if one leg of my acca loses?
The whole accumulator loses. Every leg must win (or be void) for an acca to pay out, unless your bookmaker offers acca insurance.
What happens if a match in my acca is postponed?
Most bookmakers make that leg void and settle the rest of the acca at the remaining odds. Rules on how long they wait for a rearranged game vary.
Is a parlay the same as an accumulator?
Yes. Parlay is the North American name for an accumulator. The odds are multiplied together in the same way.
