如何使用此计算器

  1. 输入分差(例如,3.5分热门为-3.5)
  2. 输入juice/vig(默认-110)
  3. 查看双方的隐含获胜概率和等效moneyline

公式

从Juice得出的隐含概率:

  • 对于负赔率: 概率 = |赔率| / (|赔率| + 100)
  • 对于正赔率: 概率 = 100 / (赔率 + 100)

分差到Moneyline(近似):

  • 每分差点 ≈ 从50/50偏移2.75%

概率到美式Moneyline:

  • 如果概率 ≥ 50%: Moneyline = -100 × 概率 / (1 - 概率)
  • 如果概率 < 50%: Moneyline = +100 × (1 - 概率) / 概率

常见问题

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.
