Common questions
How is an accumulator calculated?
Multiply all leg odds in decimal format, then multiply by your stake. For example, 2.0 × 1.5 × 2.5 × £10 = £75 return.
What happens if a leg pushes (e.g. half-ball Asian Handicap)?
Most books treat the pushed leg as odds of 1.00, so the accumulator continues with one fewer effective leg. Our calculator lets you enter 1.00 for any pushed selection.
Can a single losing leg kill the acca?
Yes. In a standard accumulator, every leg must win. One loss voids the entire return. That is the structural risk.
