Free accumulator calculator
An accumulator (acca) combines several selections into one bet, with every leg's odds multiplied together. This calculator works out your combined odds, total return and profit instantly — enter each selection's odds and your stake, and it handles doubles, trebles and bigger multiples.
How accumulator odds are calculated
Decimal odds multiply. For a treble at 1.80, 2.00 and 1.50, the combined odds are 1.80 × 2.00 × 1.50 = 5.40, so a £10 stake returns £54 (a £44 profit). Every leg must win — one loser and the whole bet loses.
- Double: 2 selections.
- Treble: 3 selections.
- Four-fold and up: 4+ selections, with odds rising fast.
Accumulator strategy
Bigger accas mean bigger odds but a much lower chance of every leg landing. Keep them short, mix uncorrelated markets, and treat them as higher-risk bets. For data-driven selections see our accumulator tips and football tips today; for each-way multiples use the each-way calculator.
