No Vig Calculator

Every price a sportsbook posts bakes in a margin, the vig. This no vig calculator strips it out so you can see the fair number underneath. Your read only beats the book if it beats the fair price, not the posted one. Paste both sides of any two-way market (a CFB total at 51.5, a spread at -110 both ways, a moneyline pair) below.

Placeholders are sample odds, not a live line.

Where we use this: the college football futures odds board prices every 2026 win total lean against the no vig line, the week 1 college football schedule carries the latest captured price on every game, and every pick grades in public on the record.

Method: multiplicative de-vig. qi = raw implied probability from each American price. M = qA + qB (the overround). Fair pi = qi / M, so the two fair probabilities sum to 100%.

Market-neutral utility. It computes numbers you supply, it does not predict outcomes or guarantee profit. Compare lines across books and make the call yourself. 21+ · research, not advice.
