Sharp Implied
Strip the thin vig out of a sharp book's two-way price to recover each side's true win probability and fair odds — then derive each team's implied score from the spread and total.
No-vig fair probabilities
Enter both moneylines to strip the vig and recover the fair line.
How it works
Sharp books embed only a thin margin into their lines. This calculator strips that vig with multiplicative devigging — dividing each side's raw implied probability by the market total — to recover the book's true estimate of each team's win probability and its fair, no-vig price.
When you also enter a spread and total, it derives each team's implied score from the line:
Home = (Total − Spread) ÷ 2
Away = (Total + Spread) ÷ 2
A negative home spread means the home side is favored, which pulls more of the total onto their score. The market margin is how far the two raw implied probabilities sum past 100% — the lower it is, the sharper the book.
