How to use no vig calculator
While you may be quick to deem sportsbooks unscrupulous for the markups they attach to odds prices, it’s good to remember that this is a standard business practice to secure a profit and ensure that they stay in business. Still, just how much vig is your sportsbook taking from your bets? And are you better off taking your chances elsewhere?
Our no vig fair odds calculator is designed to work out the “true” or “fair” odds for any outcome (bet) by removing the sportsbook’s commission (vig). To use our calculator, you’ll need to share the odds offered by the betting sites for each possible outcome. For example the odds for both teams in a moneyline bet. With the inputs provided, our calculator will work out two figures, namely the fair odds and the true probability (both with the vig axed out).
But first, here’s an overview of the fields you’ll find on our fair odds calculator:
- Odds:
These are your sportsbook’s market prices for the outcome you intend to back. By default, our calculator has this set to accept American odds (e.g., +150 or -200), but it can take different odds forms, like decimal and fractional odds. As earlier mentioned, you get two fields where you need to share the odds of both sides of the bet.
- True probability:
This is the true likelihood of the event you’re wagering on happening, shown as a percentage (%). Generally speaking, the implied probabilities from both sides of the bet should add up to 100%. However, suppose we factor in the oddsmakers’ juice/vig. This inevitably shoots up to an excess of 100%. The higher this excess is, the more we can conclude that the odds have been adjusted in the bookmaker’s favor.
- No-vig odds:
Another result you’ll see is the no-vig odds, or rather the true (fair) odds of your bet without the sportsbook’s commission.
- Calculate & reset:
Lastly are the “calculate” and “reset” buttons. The former “puts our calculator into action” after you’ve entered the odds on both sides of your bet, while the latter clears out the fields to start afresh.
Having covered the basics, here are the complete steps to using our no vig fair odds calculator for the latest odds at
new betting sites
or from a bookmaker you already have an account with. Start by identifying the event/outcome you wish to back on two sportsbooks, then:
- Open our no vig calculator
- Share the odds for each outcome in the empty fields (as provided by the sportsbook(s))
- Hit the “Calculate” button
- Then our no vig fair odds calculator will run the numbers and table the true probability and no-vig odds for your bets
Example
Let’s take a real-life example of an NFL match between the Kansas City Chiefs vs Philadelphia Eagles to bring it all together. Here are possible moneyline odds, as sourced from BetMGM:
| Teams | Moneyline |
| Kansas City Chiefs | -145 |
| Philadelphia Eagles | +125 |
When you add the inputs to our no-vig odds calculator, here are the outputs you’ll find for no-vig fair odds and true probability:
| Outcomes | Vig odds | Vig probability | No vig odds | No vig probability |
| Bet 1 (Chiefs) | -145 | 59.18% | -133.16 | 57.11% |
| Bet 2 (Eagles) | +125 | 44.44% | +133.16 | 42.89% |

No vig odds explained
As we mentioned earlier, sportsbooks are businesses, and like any other establishment, they need to generate profits to remain in operation. They achieve this by including a commission (vig or juice) to the odds they offer to guarantee that they make money regardless of the outcome of any event.
While it is standard practice, it also means that sportsbook odds and implied probabilities are inherently distorted—they do not truly reflect the likelihood of an outcome. Using our fair odds calculator, you get to remove the sportsbook’s commission and get a clearer picture of the likelihood of different outcomes, including the value of a potential bet.
How to calculate the vig: Getting down to the brass
Going back to our calculator, we were keen on making this lean and direct to the point—it tables your fair odds and true probability outright. So, what steps would you take to know how much vig betting sites have embedded (added) to their odds and, by extension, see whether you’re being ripped off?
The workaround is quite direct! Start by converting the odds into their percentage equivalent (both sides of the bet), add the two, and then subtract 100%. Here’s an example of how that would look like from our initial table for Kansas City Chiefs vs Philadelphia Eagles:
- 59.18% + 44.44% = 103.62%
- 103.62% – 100% = 3.62% vig
While the question of “fairness” is subjective, you’d want the vig to be below 5%—a (helpful) benchmark that reflects the average vig sampled from sportsbooks in the US and the world over.
Using the no vig calculator for events with more than two outcomes
Extending the discussion, how would our vig calculator work for matchups with more than two outcomes? Let’s take a 1×2 (Home, Tie, Away) bet in a premier league soccer match between Chelsea FC vs Manchester City. While the calculations can be somewhat complex, everything else remains the same, down to the formula. Here’s what it would look like:
| Outcomes | Vig odds | Vig probability | No vig odds | No vig probability |
| Bet 1 (Chelsea FC): | +280 | 26.32% | +302.27 | 24.86% |
| Bet 2 (Tie): | +300 | 25.00% | +323.44 | 23.62% |
| Bet3 (Manchester City): | -120 | 54.55% | -106.29 | 51.53% |

Why is this calculator useful
Using our no-vig calculators comes with multiple advantages! Regardless of the betting site you’re using, including the best
PayPal betting sites, you get the leeway to strip bare the odds and reveal the true value of the odds/prices, as detailed below:
Helps make informed decisions
As you’ve seen in this reading, our tool tables the true (win) probability and fair odds for your possible bet. From this, we can draw informed conclusions. For example, suppose the win probability is much higher and the odds are lower than you thought; then, there’s little value to be obtained from the bet (it might not be enough to match/compensate for the risk). Similarly, a small probability (%) shows that it might be a longshot bet, and the chances of it panning out are quite low.
It reveals the fair prices of the market
As we have shown, sportsbook odds include a vig or juice to ensure long-term profitability. While it’s not an “unfair” practice, these skewed odds might hamper your estimations or give you a bad hand. Getting the fair odds of a bet allows you to see whether you’re getting value for your bets, among other considerations.
Helps determine the best sportsbook
Picking on the above, you can calculate the vig a sportsbook is taking from your bets. Thanks to our calculator, you can easily narrow down betting sites taking the lowest vig, thus allowing for long-term profitability/value bets from your end.
Allows you to determine a bet’s expected value
Going by expected value (EV), this is a metric that tells you how much you can potentially win or lose over the long run. Among the results, our calculator tables the implied probability for each outcome on a bet, which is a key figure in the EV formula.
What other betting calculators are available
While the no vig odds calculator covers a lot of bases in determining the value of your bet and the sportsbook that potentially offers better value long-term—it is best used in conjunction with other tools, such as:
| Calculator | Description |
| Betting Odds Calculator | Our betting odds calculator assists you to determine your potential payout based on your stake and odds. |
| Tricast calculators | With our Tricast calculator, compute the stake, returns, and likely profits expected from a trifecta bet. |
| Spread to moneyline converter | Find the approximate value of a point spread bet and discover better market prices with our spread to moneyline converter. |
| Hedging calculator | Using our betting tool, you can determine how much to place on additional bets, known as “hedge bets,” to minimize potential losses (i.e., break even) or lock in a profit regardless of the event’s outcome. |
| Hold Calculator | What is the “hold” your sportsbook is charging on your bets? Our calculator is the tool you need to get an accurate estimate of the commission the betting site is taking from your bets. |
| Betting odds converter | As implied in the name, this is the tool to convert your betting odds to any format you desire—whether you’re working with decimal, American, or fractional equivalents. |
| Parlay calculator | When you’re placing (or researching) your parlay bet, our parlay calculator will cut out the long-winded math and table the total odds and payouts to expect from your parlay bet. |
Conclusion – make sure that you see the true picture
Our no vig calculator is the betting assistant you need to give an extra edge on your bets—after all, you get to poke at the odds you get for your matchups and get figures, such as the true probability and fair no vig odds. These are crucial in finding value bets, sportsbooks with better odds prices, the true possibilities of all the outcomes, and more. All you need is the odds from both sides of the bet and our calculator will work out the rest.

No vig calculator FAQ
💰 Do you charge a fee for the no vig calculator?
No, we do not charge a fee for the no-vig calculator; the betting tool is free to use for everyone.
📱 How do I calculate the juice if I have the vig probability?
Since this is the percentage of the total bets that the sportsbook keeps as a profit, you need to sum up the implied probabilities of both sides of the bet (A% + B%) and then subtract 100% from the total—what remains is the juice or vig = (A% + B%) – 100%.
🤔 How do I know a sportsbook offers the best value for their bets?
You know the sportsbook offers the best value for their bets if the vig percentage is less than 5%.
