How to Use This Calculator

  1. Select your odds format (Decimal, Fractional, or American)
  2. Enter your total stake
  3. Enter odds for each selection
  4. Set the result for each leg: Won, Lost, or Void
  5. Add more selections with the + button
  6. See combined odds, total return, and profit

Note: If any selection is lost, the entire accumulator loses. Void selections are treated 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 is an accumulator bet?

An accumulator (or acca) combines multiple selections into one bet. All selections must win for the bet to pay out. The odds multiply together, creating potentially large returns from small stakes.

What happens if one leg is void?

If a selection is void (e.g., match postponed), it’s removed from the accumulator and the bet continues with the remaining legs at reduced odds.

How many selections can an accumulator have?

There’s no theoretical limit, but most bookmakers cap accumulators at around 20 selections. A 2-fold is a double, 3-fold is a treble, and 4+ is generally called an accumulator.
