No-Vig Odds Calculator
No-Vig Odds Calculator
What are no-vig odds? No-vig odds represent the true fair price of a market with the sportsbook's margin removed. If the odds you're betting are better than the no-vig line, you're getting positive expected value — meaning the bet is mathematically profitable over time.
Enter the American odds for both sides of a two-way market. The calculator removes vig proportionally and outputs the fair probability and fair American odds for each outcome. Compare these against the lines you're being offered to spot +EV opportunities.
Divide each side's implied probability by the sum of all implied probabilities. Example: −150 / +130 → implied 60% and 43.48%. Sum = 103.48%. Fair probabilities: 60% / 103.48% = 57.98%, 43.48% / 103.48% = 42.02%. These sum to exactly 100%. Fair odds: −137.9 / +137.9.
