Accumulator Betting Calculator
Combined odds and return across selections.
How to Use This Calculator
- Set the odds format (Decimal, Fractional, or American)
- Input your total stake
- Input the odds for every selection
- Mark each leg’s result: Won, Lost, or Void
- Use the + button to append further selections
- Read off combined odds, total return, and profit
Note: A single lost selection sinks the whole accumulator. Void selections are scored at 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
Define an accumulator bet.
An accumulator (acca) folds several selections into one wager. Every selection has to win for the bet to return anything. Odds multiply across the legs, so a small stake can yield outsized returns.
What if a leg is voided?
A voided selection (say, a postponed match) drops out of the accumulator; the bet runs on with the remaining legs at correspondingly reduced odds.
What's the maximum selection count for an accumulator?
No hard theoretical ceiling exists, though most bookmakers limit accumulators to roughly 20 selections. A 2-fold is a double, a 3-fold a treble, and 4 or more is generally termed an accumulator.
