What Are True Odds?

True odds (also called no-vig odds or fair odds) are what the odds would be if the sportsbook didn't take a cut. Sportsbooks build in a margin (vig/juice) to ensure profit, which inflates the implied probability of both sides beyond 100%.

By removing the vig, you can see the actual fair probability the market assigns to each outcome. This helps you identify value bets when you believe the true probability differs from what the market suggests.

Frequently Asked Questions

What are true odds (no-vig odds)?

True odds, also called no-vig or fair odds, show what betting lines would be without the sportsbook's margin. They represent the actual market probability for each outcome. Sharp bettors use true odds from books like Pinnacle as a benchmark to find +EV bets at other sportsbooks.

How do you calculate true odds?

Convert both sides to implied probability, sum them (this exceeds 100% due to vig), then divide each probability by the total to get fair probabilities. Convert those back to odds. Our calculator does this instantly. Example: -110/-110 becomes approximately +100/+100 true odds.

Why are true odds important for betting?

True odds reveal the fair value of a bet without sportsbook markup. If a book offers +120 on a side where true odds are +100, you have a +EV (positive expected value) bet. Consistently betting when your odds exceed true odds is how sharp bettors profit long-term.

What is the Pinnacle no-vig method?

Pinnacle is considered the sharpest sportsbook with the lowest vig (often under 2%). Many bettors use Pinnacle's lines to calculate true odds, then compare to other books. If another book offers better odds than Pinnacle's no-vig line, it's likely a +EV opportunity.

How does removing vig affect implied probability?

Sportsbook odds inflate implied probabilities beyond 100%. At -110/-110, combined implied probability is 104.76%. Removing vig normalizes this to 100%, showing true probabilities of 50%/50%. This adjustment is critical for identifying value bets.
