When you’re comparing odds across sportsbooks in Colorado, the big question is simple: What are the real chances behind the line?
Our Free Colorado No-Vig Fair Odds Calculator helps you figure that out instantly. By removing the built-in sportsbook margin (“vig”), you get a clear picture of the true probability behind each side of a bet. That means smarter decisions and cleaner comparisons—no guesswork needed.

What is a No-Vig Fair Odds Calculator?
A No-Vig Fair Odds Calculator shows you the “true” odds of a matchup by taking out the juice that sportsbooks naturally build into their prices. Every Colorado sportsbook includes a margin so the odds often don’t add up to an even 100%.
This tool brings things back to neutral, giving you a clean, unbiased probability. For deeper breakdowns, visit our Colorado Betting Hub main page.
How Does the No-Vig Fair Odds Calculator Work?
At its core, the calculator takes the odds you enter, converts them into implied probabilities, adds them together, and identifies how much extra percentage the sportsbook has built in. Then it removes that margin and rebalances everything so the two sides total exactly 100%.
Step 1: Convert odds to implied probability
For negative odds (example: -110):
Implied Probability = odds / (odds – 100)
For positive odds (example: +120):
Implied Probability = 100 / (odds + 100)
Step 2: Add both sides
If the total is more than 100%, the extra is the vig.
Step 3: Remove the vig
The calculator divides each side by the total to get the fair percentages.
Quick Example
Market: -110 / -110
Raw combined probability: 104.76%
Fair implied probability (after removing vig): about 50% each
Fair odds: roughly -100
Fair Payout Example
A $100 bet at even, no-vig odds returns $100 in winnings.

No-Vig Fair Odds Value and Strategies
This page is all about using the calculator, not a long strategy guide—but here are a few quick pointers to get the most out of it:
Quick Tips
-
Compare the calculator’s fair odds with the posted line—if the sportsbook number is better, that’s a good sign.
-
Colorado has several legal sportsbooks, so checking two or three before locking in a bet can make a real difference.
-
Focus on small percentage edges instead of chasing the biggest payout.
-
Try running alternate lines through the calculator—sometimes the edges hide there.
-
If odds shift suddenly, recheck the fair number to see if the move actually makes sense.

Frequently Asked Questions
What does the No-Vig Calculator actually do?
It removes the sportsbook margin from a betting line and shows you the true, neutral odds behind the matchup.
Why do I need both sides of the odds?
Because the vig is built into the combination of both prices. The calculator needs both numbers to figure out how much margin is in the market.
Can I use this for spreads and totals?
Yes—if a market has exactly two sides, you can plug them in and get the fair odds.
Does this tell me which bet to make?
No. It simply shows unbiased probabilities. It’s still up to you to decide how to use that information.
Are fair odds always even?
Only when both sides are priced evenly. If one side is a stronger favorite, the fair numbers will reflect that.
How often should I use the calculator?
Any time you’re comparing lines across sportsbooks or see odds move after news or betting activity.
Why do sportsbooks add vig anyway?
It’s how they build an edge into the market. Without it, both sides would add up to exactly 100%.
Do different Colorado sportsbooks have different vig levels?
Yes. That’s why checking multiple books helps you spot better prices.
Can I run futures odds through this?
Only for two-way futures. Multi-team or multi-player futures require a different approach.
What’s the biggest benefit of removing the vig?
Clarity. You can see the real probability underneath the sportsbook pricing and judge whether the listed odds are fair.
