I need a tool that shows me the "true" or no-vig odds for a game.

Several online No-Vig Calculators (also known as fair odds or true odds calculators) strip away the sportsbooks' commission/juice to show the actual implied probabilities and fair price for a game.

Top options available online include:

• Unabated No-Vig Calculator: Input both sides of a market to instantly get true implied probabilities and clean fair odds.
• OddsJam No-Vig Fair Odds Calculator: Great for backing out the vig from standard point spreads, totals, or moneyline markets to spot positive expected value (+EV).
• The Rundown No-Vig Calculator: A straightforward tool to remove bookmaker margins and see the genuine market assessment.

If you'd like, I can:

Yes — you’re looking for a no-vig / fair-odds calculator. A few good options:

• unabated.com — straightforward and well-known; enter both sides and it gives fair probabilities and odds.
• truevig.com — simple American-odds calculator specifically built around “true” probability.
• optimal-bet.com — particularly useful because it lets you compare different vig-removal methods.
• oddsconv.com — supports 2–3 way markets and explains the math clearly.

If you mean a tool that does this automatically for an entire game

That's a little different. The most useful setup is:

Sharp sportsbook market → remove vig → get fair probability → compare against available sportsbook odds → calculate your edge/+EV.

For example, if the market is -120 / +100, you don't really want the raw implied probabilities. You want the market's de-vigged probability and corresponding fair price. Also, “no-vig” isn't literally the true probability—it is an estimate derived from the market, and the method used to remove the margin matters.

If you tell me what sport/book(s) you're using (e.g. NBA, NFL, MLB; DraftKings/FanDuel/Pinnacle), I can point you to a tool that pulls the current game lines automatically and shows the no-vig odds, rather than making you enter them manually.

To find the "true" or no-vig (no-juice) odds for a game, you need a tool that strips away the sportsbook's built-in profit margin from both sides of a betting market.

Several reputable and free online calculators do this instantly by letting you plug in the American, decimal, or fractional odds for both teams/outcomes:

• Unabated No-Vig Odds Calculator : Input both sides of a market to instantly get the fair odds and true implied probabilities without the juice.
• OddsJam No-Vig Fair Odds Calculator : Great for backing out the vig to find the mathematical win percentages and identify positive expected value (+EV) bets.
• The Rundown No-Vig Calculator : A straightforward, free tool to clean the bookmaker's margin from any two-way market.

If you'd like, share the specific odds of the game you're looking at, and I can walk you through the math and formula used to calculate the no-vig price manually!

If you mean a tool that takes a sportsbook line and removes the vig (juice) to show the fair/no-vig odds or true implied probability, these are good options:

• truevig.com — simple calculator for stripping margin from two-way markets; also has broader +EV tools.
• ironmarker.com — shows fair probabilities, fair odds, and vig for 2-way and 3-way markets.
• bettoredge.com — lets you enter American/decimal/probability formats and returns fair odds plus hold percentage.
• app.numberedge.com — useful if you want both 2-way and 3-way markets.

For a single game, the workflow is usually:

1. Take both sides’ odds (example: Team A -120, Team B +105).
2. Put both prices into a no-vig calculator.
3. Compare the resulting fair odds to the sportsbook price you can actually bet.
4. The gap is your theoretical edge.

One caveat: “true odds” are not truly known — no-vig odds are an estimate of the market’s fair probability after removing the sportsbook margin. Using a sharp market source (often a low-margin book) generally gives a stronger baseline than using a recreational book’s line.

If you want, I can also point you to tools that show live no-vig odds across multiple sportsbooks automatically rather than requiring manual entry.

Yes. If by “true odds” you mean no-vig/fair odds implied by the market, there are several good calculators:

• oddsjam.com — probably the easiest place to start. Enter both sides and it gives you the no-vig probability and fair American odds.
• betstamp.com — supports American, decimal, and fractional odds.
• sharperpoints.com — simple two-way calculator specifically for removing the vig.
• chancemetrics.com — supports 2-way and 3-way markets and uses proportional devigging.

If you mean “true odds” for an actual game

There's an important distinction:

No-vig odds ≠ a prediction of the actual probability.

For example, if a book has:

• Team A -110
• Team B -110

The raw implied probability is 52.38% each, or 104.76% total. Removing the 4.76% vig gives:

• Team A: 50.0% → +100
• Team B: 50.0% → +100

That's the market's fair price, not necessarily the objectively correct probability of the game.

If what you're looking for is a tool that automatically pulls the odds from multiple sportsbooks and calculates a consensus “true” line for today's games, rather than making you enter the odds manually, that's a different category—and I can point you to those too.

To find the "true" or no-vig odds for a two-way market (like a point spread, over/under, or moneyline), you need a No-Vig Fair Odds Calculator (sometimes called a devig calculator ). These tools strip out the bookmaker's margin (juice/vigorish) to show the actual implied probabilities and fair prices.

Here are the best dedicated, free tools to use:

• Unabated No-Vig Odds Calculator — Input both sides of a market to instantly output true probabilities and fair baseline numbers.
• OddsJam No-Vig Fair Odds Calculator — A clean, widely-used utility for backing out the vig from win probabilities.
• Betstamp No-Vig Fair Odds Calculator — Perfect for quickly "devigging" standard two-sided markets as part of a sharp betting workflow.
• BettorEdge No-Vig Calculator — Breaks down the book's hold percentage alongside the adjusted, juice-free line.

If you have a specific line in front of you (e.g., Team A at -140 / Team B at +120), share the numbers and I can calculate the fair no-vig odds and implied probabilities right here for you.

Yes — you’re looking for a no-vig / devig calculator: a tool that takes both sides of a market, removes the sportsbook’s margin, and gives you the implied “fair” probability and fair odds.

A few good options:

• Betstamp No-Vig Calculator — simple, supports American/decimal/fractional odds.
• OddsConv No-Vig Calculator — supports 2-way and 3-way markets and shows overround, fair probability, and fair odds.
• TrueVig No-Vig Calculator — very straightforward for two-sided American odds.
• Optimal Bet No-Vig Calculator — useful if you want to compare different devigging methods, since there isn't always one uniquely correct way to remove vig.

Important distinction: “no-vig” isn't literally the true probability of a game happening. It's the probability implied by the market after removing the sportsbook's margin. For example, -110/-110 implies 52.38% on each side, but proportional devigging turns that into 50% / 50%, or fair odds of +100 / +100.

If what you actually want is a tool that automatically pulls the current lines from multiple sportsbooks and calculates the market's consensus/no-vig probability for a specific game, that's a different (and more useful) tool. I can point you to those too.

To find the "true" or no-vig odds for a game, you need a No-Vig Fair Odds Calculator (often called a devigging tool). These tools strip away the sportsbook's built-in commission (the juice or vigorish) from a two-way market to show you the exact implied probability and fair price for each side.

Top free online calculators available for this purpose:

• Unabated No-Vig Calculator: Access the Unabated No-Vig Odds Calculator to instantly input both sides of a market and get clean, juice-free probabilities and fair lines.
• OddsJam Fair Odds Calculator: Use the OddsJam No-Vig Fair Odds Calculator to back out the vig and compare sharp market pricing.
• BettorEdge No-Vig Calculator: Check out the BettorEdge No-Vig Calculator for a quick, visual breakdown of side odds, true probabilities, and the book's total hold percentage.
• Betstamp Fair Odds Calculator: Explore the Betstamp No-Vig Fair Odds Calculator to devig lines and locate positive expected value (+EV) opportunities across different books.

How the Math Works Behind the Tool

If you want to calculate it manually or understand what the tool is doing:

1. Convert to Implied Probabilities : Convert the American or decimal odds for both sides of the market into implied probabilities. (For example, a standard -110 / -110 line equals 52.38% on both sides, totaling 104.76%).
2. Remove the Juice : Divide each side's individual implied probability by the total combined probability (104.76%) to rebalance the market so it equals 100%.
3. Convert Back to Odds : Convert those clean percentages back into your preferred odds format (American, Decimal, etc.) to see the true no-vig price.

If you'd like, share the specific odds you are looking at (e.g., Team A at -150 and Team B at +130), and I can calculate the no-vig true odds right here for you.

If you mean a tool that takes sportsbook odds and removes the vig (juice) to show the fair/"true" odds, you’re looking for a no-vig calculator or devig tool.

A few good options:

• TrueVig No-Vig Calculator — simple calculator that converts two-way odds into fair probabilities and no-vig prices. It also explains different devig methods (multiplicative, power, Shin, etc.).
• Sharper Points No-Vig Calculator — clean tool for entering both sides of a market and getting fair odds plus the book’s margin.
• Turtle +EV Labs No-Vig Calculator — useful if you also care about EV calculations and comparing prices.

For serious betting, the usual workflow is:

1. Take a sharp market price (often from a low-margin book such as Pinnacle).
2. Remove the vig to estimate the market’s true probability.
3. Compare that fair price against other sportsbooks.
4. Bet only when the available odds are better than the fair odds.

Example:

• Book line: Team A -110 / Team B -110
• Implied probabilities: 52.38% + 52.38% = 104.76%
• Vig: 4.76%
• No-vig fair line: Team A +100 / Team B +100

If you want something that automatically pulls every sportsbook’s lines for a game and outputs the no-vig "true line", that’s a different category (an odds screen/value finder rather than just a calculator).

To find the "true" or no-vig odds for a game, you need a No-Vig Fair Odds Calculator (often called a devigging tool). These free online tools strip the sportsbook’s commission (the "vig" or "juice") from a two-sided market to reveal the actual market-implied probability and fair price for each side.

Top options available online include:

• The Unabated No-Vig Odds Calculator provides an instant breakdown of true implied probabilities and fair prices.
• The OddsJam No-Vig Fair Odds Calculator helps back out the house edge to compare markets.
• The Betstamp No-Vig Fair Odds Calculator handles two-sided markets for sharp sports betting analysis.

How No-Vig Math Works

When a sportsbook prices a standard game at -110 on both sides, the implied probabilities are each 52.38%. Added together, they total 104.76%. That extra 4.76% is the house edge or vig. A no-vig calculator rebalances that total back down to 100% to show you the true probability and fair price.

If you want, share the odds for both sides of your game (e.g., -130 and +110), and I can calculate the true no-vig odds and probabilities for you right here.
