How acca odds work
Multiply the decimal odds of all legs. Four legs at 1.45, 1.90, 2.10 and 1.65 give 9.55. ₦1,000 on that returns ₦9,546. Check any slip with the accumulator calculator.
Why each leg matters
The chance of an acca landing is the chances of each leg multiplied together. Even "safe" legs add up:
| Legs at 1.30 | Total odds | Implied chance |
|---|---|---|
| 3 | 2.20 | 45.5% |
| 5 | 3.71 | 26.9% |
| 8 | 8.16 | 12.3% |
| 10 | 13.79 | 7.3% |
Ten legs that each look like near-certainties still lose more than nine times out of ten, at the prices given.
Acca bonuses
Many bookmakers pay a bonus on winning accas: a percentage of the winnings that grows with the number of legs. Usually there is a minimum number of selections and minimum odds per leg. The bonus is paid on the profit, not on the stake, and it does not change the chance of winning.
Void legs and cash out
- Void or postponed legs usually count at 1.00. The acca carries on with fewer legs and lower odds.
- Cash out lets you settle early for an offer below the fair value. See the cash out calculator.
- Hedging the last leg can lock a profit; see our hedging guide.
Checklist before you place an acca
- Count the legsWould you take each leg as a single at that price?
- Check the implied chanceThe calculator shows it. Is it a chance you are comfortable with?
- Read the bonus termsMinimum odds per leg can make one of your picks not count.
- Consider a system betA system bet pays even if a leg loses, at a higher total stake.
Questions

Is a long acca a bad bet?
It is a high-risk bet with compounding margin. It can be fun with a small stake, but it is not a way to make steady money.
