How it works
An accumulator pays only if every leg wins, at the odds of all its legs multiplied together. Enter the stake, the number of legs and each leg's decimal odds. The calculator gives the combined odds, what the stake returns if every leg wins, and the chance those odds imply of every leg winning.
Worked through
A £10 treble at 2.00, 1.50 and 3.00.
| It shows | Value |
|---|---|
| Combined odds | 9.00 |
| Return if all legs win | £90.00 |
| Implied chance (all legs) | 11.11% |
The three prices multiplied together make 9.00. If all three legs win, the £10 stake comes back as £90.00, the stake included. If any leg loses, nothing comes back.
Questions
How are acca odds worked out?
Multiply the decimal odds of every leg together. What the stake returns if every leg wins is the stake multiplied by those combined odds, with the stake included.
What if a leg is void?
Bookmakers usually drop a void leg and settle the rest as a smaller acca. Set one fewer leg and leave that price out.
Can I enter fractional odds?
It takes decimal odds. Turn a fractional price into a decimal one with the odds converter first.
