Calculate an Accumulator
Multiply selection prices into the full combined return.
How to Use This Calculator
- Pick your odds format (Decimal, Fractional, or American)
- Drop in your total stake
- Add the odds for each selection
- Flag the result for every leg: Won, Lost, or Void
- Tap the + button to stack on more selections

Heads up: One lost selection sinks the whole accumulator. Void legs are handled 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 exactly is an accumulator bet?
An accumulator (or acca) rolls several selections into a single bet. Every selection has to land for the bet to pay. The odds compound together, which can turn a small stake into an outsized return.
What happens when a leg is voided?
When a selection is voided (say a match gets postponed), it drops out of the accumulator and the bet rolls on with the remaining legs at lower combined odds.
Is there a cap on how many selections I can add?
There’s no hard limit in theory, though most bookmakers stop accumulators around 20 selections. A 2-fold is a double, a 3-fold is a treble, and anything 4-fold or above is usually labelled an accumulator.
