Accumulator Tool
Combine several selections and see how the multiplied odds build your potential return.
How to Use This Calculator
- Pick the odds format: Decimal, Fractional, or American
- Input your total stake
- Input the odds for every selection
- Mark each leg: Won, Lost, or Void
- Use the + button to add selections
- Read off combined odds, total return, and profit
Note: A single lost selection kills the whole accumulator. Void selections count as odds of 1.0 (refunded).
Formula
Combined Odds = Odds₁ x Odds₂ x Odds₃ x … (all decimal odds multiplied)
Total Return = Stake x Combined Odds
Profit = Total Return - Stake
Void legs are removed from the calculation (odds become 1.0). If any leg loses, the total return is $0.
Frequently Asked Questions
What does an accumulator bet mean?
An accumulator (acca) rolls several selections into one bet. Every selection has to win for it to pay. Odds multiply across legs, so a small stake can return a lot.
What if a leg is voided?
A void selection (e.g. a postponed match) drops out of the accumulator, and the bet runs on with the remaining legs at lower combined odds.
How many legs can an accumulator hold?
No fixed limit applies, though most bookmakers cap accas near 20 selections. Two legs is a double, three is a treble, and four or more is usually called an accumulator.
