Acca calculator and checker
Add your legs and stake to see your combined odds and return. For matches we cover, we also show our chance next to the bookie's, so you can see which legs are worth their place.
Example: three legs at 2.00 with a £5 stake give combined odds of 8.00 and a £40 return. All 3 legs landing together: about 1 time in 8.
Add odds for every leg and a stake to see your result.
Chances are multiplied as if the legs are independent. Most accas lose, even good ones. Stake small.
How the acca calculator works
Combined odds are the odds of every leg multiplied together. Each leg's odds also become a chance (see odds to probability), and multiplying those gives the bookie's chance of the whole slip landing. Our chance comes from the model, explained in how it works.
Why accas usually lose
Four legs at 70% each land together only about 1 time in 4. Every extra leg multiplies in another chance of failure, and the bookmaker's margin is charged on every leg.
Questions
How do I calculate acca odds?
Multiply the decimal odds of every leg. Three legs at 2.00 make 8.00, so £5 returns £40 if all three win.
What does the checker add?
For matches we cover, it shows whether our model rates each leg higher or lower than the bookmaker does.
Is this betting advice?
No. Sidefoot is a research tool. Our chance is a model estimate, not a certainty.
