Questions fréquentes

What is a point spread?

A point spread is a handicap applied to the favored team to even out the betting. If a team is -3.5, they must win by 4 or more points for the bet to win. The underdog at +3.5 wins if they win outright or lose by 3 or fewer points.

How do you convert a spread to a moneyline?

Each point of spread roughly corresponds to 2.75% of win probability. A -3.5 spread implies approximately 59.6% win probability, which converts to roughly a -148 moneyline for the favorite.

What is juice or vig?

Juice (or vig) is the commission the sportsbook charges. Standard juice is -110 on each side, meaning you must bet $110 to win $100. This built-in margin ensures the sportsbook profits regardless of the outcome.

Is this conversion exact?

The spread-to-moneyline conversion is an approximation. The exact relationship depends on the sport, the specific matchup, and market conditions. It works best as a quick reference for NFL and NBA betting.
