The Stats Formulas Behind Every Sport
Sports statistics range from simple counting stats to genuinely sophisticated rating systems — a batting average is straightforward division, while a golf handicap or a tennis Elo rating accounts for course difficulty or opponent strength in ways that take real formulas to calculate correctly. Twenty-eight calculators here span team sports, individual sports, and fantasy scoring.

Why Golf Handicaps Use Course Rating and Slope, Not Just Score
A golf handicap isn't based on raw scores alone — it adjusts for course rating (the expected score for a scratch golfer) and slope rating (relative difficulty for a bogey golfer versus a scratch golfer), which is exactly why the same round score can produce a different handicap differential depending on which course it was shot on. This adjustment is what makes handicaps meaningful for competition between players of different skill levels on different courses, rather than just a raw scoring average that would unfairly favor players who happen to play easier courses more often.
Frequently Asked Questions
Why does NFL passer rating have a maximum cap of 158.3?
The formula caps each of its four components at a maximum value before combining them, which produces a mathematical ceiling on the final score regardless of how exceptional a specific game's stats are.
Do all fantasy leagues use the same scoring system?
No — leagues customize point values for different statistical categories (like PPR versus standard scoring in fantasy football), so the same player's real-world stat line can produce different fantasy point totals across different leagues.
