What is a No Vig Fair Odds Calculator?

This tool removes the sportsbook's built-in margin (vig or juice) from two-way betting lines, revealing the "fair" odds and true win probabilities that add up to exactly 100%.

By stripping out the overround, you can better evaluate value across books—if offered odds are better than these fair odds, you may have a positive expected value (+EV) bet.

  • Standard -110/-110 lines include ~4.76% vig → Fair odds: +100/+100 (50% each).
  • Skewed lines (e.g., -150/+130) → Fair odds adjust proportionally without the house edge.
  • Ideal for moneylines, point spreads, totals, and comparing sharp vs. recreational books.

How to Use the No Vig Fair Odds Calculator

  • Enter the current American odds for both sides (include + or -).
  • Click "Calculate" to see the vig percentage, fair no-vig odds, and true probabilities.
  • Line shop: If another book offers better than these fair odds, that's potential value!
  • Pair with our standard No Vig Calculator for additional insights.
