Accumulator (Acca) Calculator
An accumulator multiplies the odds of every leg, so all legs must win (or be void) for it to pay. Void legs are treated as 1.0 and the acca drops a fold.
Worked example
£10 treble at 1/1, 1/2 and 2/1 (decimal 2.0 × 1.5 × 3.0 = 9.0) returns £90. If the 1/2 leg is void, it becomes a £10 double at 6.0, returning £60.
FAQs
How are acca odds calculated?
Multiply the decimal odds of every leg. Fractional odds are converted to decimal first (5/2 = 3.5).
What happens if one leg of my acca is void?
That leg counts at odds of 1.0, so the bet continues as a smaller accumulator.
Can I bet an accumulator each-way?
Yes. The place part is a separate acca at place odds that pays if every leg wins or places.
