A no vig calculator shows you the true odds of a bet by removing the sportsbook’s hidden fee.
Sportsbooks add a small commission called the vig (short for vigorish) into their odds. This is how they make money. Because of the vig, the total probability of all outcomes adds up to more than 100%.
A no vig calculator removes that margin and shows you the true win probability and fair odds — the real price of the bet.
It works for esports betting, traditional sports, and any 2-way or 3-way market.
That’s why we built this no vig calculator: to help you understand what the odds are really worth before you place a bet and to help you find the sites with the most competitive odds.

No-vig odds remove the sportsbook margin (the “vig” or “juice”) from both sides of a market. This gives a cleaner estimate of each side’s fair probability.
Sportsbooks price outcomes so the implied probabilities usually add to more than 100%. This calculator normalizes those probabilities back to 100% to estimate fair pricing.
Use no-vig pricing for line shopping, model validation, and expected value analysis before placing a bet.
If you're analysing markets seriously, you’ll likely need more than one calculator. Use the tools below to deepen your analysis:
Once you’ve calculated fair odds, execution matters.
Even small pricing differences can impact long-term profitability. Comparing sportsbooks allows you to place bets at the most competitive lines available.

In sports betting, the vig is the small fee the sportsbook builds into the odds to make money.
For example:
Those odds make it look like each team has about a 52% chance of winning.
But if you add them together, it equals 104%. That extra 4% is the sportsbook’s profit. This is called the overround.
When you remove the vig, both teams go back to a true 50% chance — which gives fair odds of +100 (2.00).
Professional bettors remove vig before making any pricing decision.
Use a no-vig calculator when:
Without removing vig, you cannot measure true edge accurately.
Removing vig reveals the real probability of an outcome.
To identify potential value:
A 2-way market has only two possible outcomes — one side wins, the other loses.
Common examples include:
Because there are only two outcomes, removing the vig simply adjusts both probabilities so they add up to exactly 100%.
A 3-way market has three possible outcomes.
These are common in:
The three outcomes are:
In 3-way markets, the sportsbook spreads its margin across all three outcomes. Removing the vig requires adjusting each probability proportionally so the total equals exactly 100%.
Why this matters: The more outcomes in a market, the more carefully the vig must be redistributed — which is why a proper no-vig calculator needs to handle 2-way and 3-way markets differently.
American odds:
Decimal odds: 1 ÷ Decimal Odds
Percentage: Convert directly (e.g. 52% = 0.52)
For 2-way markets:
p_no_vig = p ÷ (pA + pB)
For 3-way markets:
p_no_vig = p ÷ (pA + pB + pC)
This ensures the total probability equals 100%.
Decimal fair odds:
1 ÷ p_no_vig
These represent the true price of the market.
