Accumulator odds calculator
An accumulator multiplies the odds of every leg. It also multiplies the risk: one lost leg loses the whole slip.
What to know
Combined odds = the product of the leg odds. Four legs at 1.50 give 5.06.
The implied probability is the product of each leg's probability. Four legs of 67% each win together only about 20% of the time.
Each leg carries its own bookmaker margin, and the margins compound. That is why long accumulators are expensive even when each leg looks fine.
