A football accumulator — commonly called an acca — combines multiple selections into one bet. Normally every required leg must win for the accumulator to return a profit, subject to the bookmaker’s rules.
Simple Example
Three selections at decimal odds of 1.50, 1.80 and 2.00 combine to produce odds of 5.40. A £10 winning stake would return £54.
Accumulator Terminology
- Double: two selections
- Treble: three selections
- Four-fold: four selections
- Five-fold: five selections
Why Potential Returns Grow Quickly
The individual prices multiply together, but the combined probability also falls. If three independent events each have a 60% chance, the chance of all three winning is 21.6%.

What Markets Can Be Included?
Depending on the operator, accumulators can contain match winner, double chance, Asian Handicap, goals, BTTS, player markets, corners and cards.
Accumulator vs Bet Builder
An accumulator usually combines selections from different events. A bet builder usually combines several selections within the same match.
Why One “Safe” Leg Can Ruin an Acca
There is no truly safe leg. A short-priced favourite can still lose and destroy the entire accumulator while adding relatively little to the combined return.
Conclusion
A football accumulator combines several selections into one wager with multiplied odds. The potential return rises, but so does the chance that at least one component fails.
