No-vig fair odds calculator
| Implied | Fair probability | Fair odds | |
|---|---|---|---|
| Side A / Over | 52.4% | 50.0% | +100 · 2.00 · 1/1 |
| Side B / Under | 52.4% | 50.0% | +100 · 2.00 · 1/1 |
How to remove the vig
Add up the implied probabilities of all outcomes: the excess over 100% is the vig. -110 / -110 gives 52.4% + 52.4% = 104.8%, a 4.8% margin.
Divide each implied probability by the total to get the fair probability: 52.4 / 104.8 = 50%, fair odds +100.
Why fair odds matter
Fair odds from a sharp market like Pinnacle are the best public estimate of the true probability. Clutch uses exactly this calculation on Pinnacle for every NBA prop in the terminal.
Frequently asked questions
What is the vig?
The vig (or juice) is the sportsbook's margin built into the odds: the amount by which the implied probabilities exceed 100%.
Which method does this calculator use?
The proportional (multiplicative) method: each implied probability is divided by their sum. It is the standard method and works well for balanced markets.
The Clutch terminal does these calculations for every NBA player prop, using Pinnacle's no-vig price as the reference. Free with an account.
