### How to Use The No Vig Calculator

In order to make a profit, sportsbooks add a vig to their odds. By doing this they don’t offer us the true odds or fair odds. However, we can calculate the fair odds using the no vig calculator.

All we need to provide for the calculator is the odds for both teams or outcomes. Enter the moneyline odds into the **Outcome One Odds** and **Outcome Two Odds** fields like the image below.

In addition, the calculator will display the current market vig / hold percentage to the right of the market odds you’ve entered.

Once you have entered the odds for both outcomes. The Fair Odds / No Vig Odds will be displayed at the bottom of the calculator like the image below.

Also the implied probability without the vig is displayed as percentages underneath the no vig odds.

### How to Calculate No Vig Odds

In order to calculate the no vig odds, we first need to calculate the vig percentage for the market in question.

We do this by converting the moneyline odds for each outcome into an implied probability using the below formulas

**Negative Odds**:- (Negative Odds Made Positive / (Negative Odds Made Positive + 100)) * 100 = implied probability

**Positive Odds:**- 100 / (Positive Odds + 100) * 100 = implied probability

Next we add together the implied probabilities of both outcomes to get a **total market probability** which is the true market probability of 100% plus vig.

Once we have the **total market probability** we can calculate the no vig probability of each outcome using the formula below.

Outcome Implied Probability / Total Market Probability = No Vig Probability

Finally, now that we have the no vig probability we can convert this into the no vig odds or the true odds. We will use one of the formulas below depending on whether the no vig probability is equal and above (>=) 50% or below 50%

**Equal to or Above 50%:**- – (probability)/(100 – probability) * 100 = Moneyline Odds

**Below 50%:**- ((100 – probability)/(probability) * 100) = Moneyline Odds
