How Accumulator Odds Are Calculated
Decimal odds already include your stake, so for an acca you simply multiply the odds of every leg, then multiply by the stake.
| Legs | Odds | Total odds | Return on ₦1,000 |
|---|---|---|---|
| 3 | 1.50 × 2.00 × 1.80 | 5.40 | ₦5,400 |
| 5 | 1.50 each | 7.59 | ₦7,594 |
| 8 | 1.50 each | 25.63 | ₦25,629 |
| 10 | 1.50 each | 57.67 | ₦57,665 |
What the Acca Bonus Adds
Most acca bonuses are a percentage of your profit. A 10% bonus on the 3-leg slip above adds 10% of ₦4,400, so ₦440. Enter the bonus percentage of your bookmaker to see the effect. Compare bookmakers on our acca bonus page.
The Implied Chance
Total odds of 5.40 imply a chance of about 18.5% (1 divided by 5.40) that every leg wins, and slightly less once the bookmaker's margin is counted. Watch how fast this number falls as you add legs.
Adding a "safe" leg at 1.20 still cuts your chance of winning by a sixth. There are no free legs in an accumulator.
Accumulator Calculator FAQ
How do I calculate acca winnings?
Multiply the decimal odds of all selections, then multiply by your stake. Subtract the stake for the profit.
What happens if a leg is void?
Most bookmakers count a void or postponed leg at odds of 1.00, and the rest of the acca stands.
Can I use fractional odds?
Convert them first: divide the top number by the bottom and add 1. 5/2 becomes 3.50. The odds converter does it for you.
