Accumulator calculator

Big odds. Bigger margin.

An accumulator multiplies the odds of every leg — and the advertised payout looks huge. Add your selections and see the other number: the implied probability, and how the bookmaker surcharge stacks up with each leg.

The idea

Every leg multiplies the cut.

A single bet carries the bookmaker margin once. A four-leg accumulator carries it four times over. The combined price looks generous because the chance of collecting it is tiny — that is the trade the advertising never shows.

Every selection you add multiplies the odds — but also the bookmaker margin. An accumulator of 2 matches stacks the bookmaker surcharge 2 times. That is why they pay so much: they almost never land.
