Accumulator Calculator

Calculate combined accumulator odds

An accumulator multiplies the decimal odds of every included leg. Enter at least two prices and up to six legs. The calculator returns the combined decimal odds, the total gross return for your stake, the potential profit and the combined implied probability of the accumulator price.

For example, three legs priced at 1.70, 1.90 and 2.10 combine to decimal odds of 6.783 before any bookmaker-specific rule changes.

Why accumulator risk grows quickly

Every required leg must settle as a winner for a standard accumulator to win. Adding a short-priced selection can increase the potential return but also introduces another failure point. Combined odds should not be confused with the true probability of all legs winning, especially when selections are correlated.

Use the calculator before confirming a betslip

• Compare the calculated combined price with the bookmaker betslip.
• Check whether any legs are related or subject to same-game pricing rules.
• Review void, push and abandoned-event rules.
• Keep the total stake within a pre-set betting budget.
