Accumulator Bet Calculator

An accumulator, often called an "acca," is a single bet that combines multiple selections from different events, requiring every single selection to win for the bet to pay out. Popular in football and horse racing, accas offer the appeal of high payouts from small stakes due to compounding odds—winnings from one successful leg become the stake for the next. These bets are defined by their "length" (e.g., double, treble, 4-fold), where more selections increase both potential returns and risk, making an accumulator calculator essential.

A standard accumulator bet functions by compounding the odds of each successful selection sequentially. This means the winnings from one winning "leg" automatically become the stake for the next. For example, with four selections (A, B, C, D), your initial stake on A, if it wins, rolls over its returns to become the stake for B. This continues for C, and then D. You only receive the full, large payout if every single selection wins, as the entire process relies on this sequential multiplication of odds. An Acca Calculator simplifies this by automating the compounding to show your potential winnings.
