No-vig calculator
Vig is the bookmaker's cut, built into both prices.
Enter both prices
What no-vig means
No-vig means the two prices with that cut removed, so the two chances add up to 100 percent.
Implied probability is the chance a price stands for, with the vig still in it.
The method
The method is multiplicative. We add up both implied chances, then divide each one by that total so they add up to 100%.
It is the same method the closing line calculator uses.
Then check the close
The closing line is the last price before the game starts.
CLV is the gap between your price and the fair closing price.
Use the fair close when you check closing line value.
The same math sits inside Did you beat the close?
A worse price, counted over many bets, is on what that price cost you.
