No-Vig Fair Odds Calculator for Sports Betting (May 2025)

Bookies.com readers can benefit from a no-vig calculator before they place their bets at the best sports betting sites. If there’s a money line or spread, you can enter these odds into the no-vig fair odds betting tool. 

In doing so, you are then given the no-vig percentage along with the no-vig odds. It helps you understand real probabilities and prices when it comes to your sports betting. 

This no vig calculator guide will help you understand the definition of no-vig. We can also elaborate on fair odds and how they can be derived using a no-vig odds calculator. 

You can therefore understand the difference between sportsbook odds compared to no-vig odds. We’ll help you find true lines with your betting and the best way to use a no-vig line calculator. 

No-vig means eliminating the house edge of a sportsbook. Each bookie will build in vig to each betting market. That way, they can take a commission from every bet. However, it regularly means that bettors don’t get the odds that accurately reflect the probability of a selection winning. Achieving no-vig provides a far greater chance of landing a winning return on a long-term basis. Let's explore the following example:

We might have the Miami Dolphins at the following NFL odds on the moneyline:

➝ DraftKings -110

➝  bet365 +100

➝ FanDuel +120

If we use the no-vig betting calculator for the DraftKings Sportsbook odds, it suggests that the Dolphins have a 50% chance of winning the game. However, the FanDuel odds give us a far bigger potential return on our stake. Therefore, we would take the latter selection, knowing that there’s value in betting at the bigger odds. 

At a sportsbook, you will always see implied odds. These are the odds you can wager on. The sportsbook odds don’t strictly reflect the probability of a pick winning. That is because they have an in-built vig. 

However, we can establish the true odds by using a fair-odds calculator. This will eliminate the vig and demonstrate the odds that would be available if a sportsbook weren’t looking to build in an edge. 

The no-vig calculator works in the sense that you add in the sportsbook odds for a two-way market. You can then see the no-vig percentage along with what the no-vig odds should be. If you can, then find a sportsbook offering either selection at bigger odds than it’s worth taking from an expected value point of view.

The no-vig fair odds betting tool will neatly illustrate the difference between sportsbook odds and no-vig odds. A sportsbook will create a betting market where there’s a margin built into the bet. If a sportsbook were to offer heads or tails betting, it might offer -105 for both options.

Odds of -105 imply a probability of 51.3%, although we know that the correct odds for heads and tails would be +100. That sums up the difference between sportsbook odds and no-vig odds. A no-vig calculator would outline this, and it’s worth using when you are looking to get value on your NFL and NBA wagers. 

It stands to reason that a no-vig calculator will work best when finding out fair odds. It’s always good to find out the latter to see if your probability is higher or not. When betting against a sportsbook, you always need to remember that built-in juice. However, the fact that sportsbooks offer different odds means we can take advantage. 

Houston Rockets +5.5 at odds of -110 could be playing Golden State Warriors -5.5 at NBA odds of -110. Entering these numbers into a no-vig fair odds betting tool will outline that both picks have a 50% probability of winning. That means no-vig odds of +100 for each selection. 

The fair-odds calculator will always give you definitive odds, and it’s the goal to try and find bigger odds with a different sportsbook. 

The average vig percentage depends on several factors. Firstly, each sportsbook will have a different approach to vig. Secondly, it depends on the sport and the market. It’s pretty common to find a 5% vig built into the betting odds. The no-vig line calculator can reveal this number every time. 

Let’s say that the Miami Dolphins and Chicago Bears are -110 on the moneyline at BetMGM Sportsbook. That means that a $110 bet on each team would return $210, although you would have laid out $220. The profit that BetMGM makes here is $10. If we divide this amount by the actual payout, then we are left with 0.0476, which is 4.76%.

It’s important to find the true lines in sports betting. This then enables you to see the vig that is being applied. A no-vig calculator is one of the best ways to visibly remove the juice. So that you can see the fair odds and work out how to wager by finding the true lines.

OddsJam provides so many valuable betting tools that can be used to good effect. A no-vig odds calculator is just one of many resources that can be used when you’re a subscriber. Soon enough, you will be entering all odds into a no-vig betting calculator to approach your betting more smartly.

If the no-vig fair odds betting tool suggests that the Golden State Warriors are +100 on the moneyline, then we need to find a sportsbook that is offering those odds. It’s even better if a bookmaker has odds such as +105 or +110 for this pick. That means you are removing vig and also enabling juice from your own side.

The good news is that it’s a simple case of inputting the numbers to achieve the result. We recommend subscribing to OddsJam and testing their No Vig Fair Odds Calculator.
