The NFL Passer Rating Formula

NFL passer rating uses four components, each capped at 2.375: Completion %, Yards per attempt, TD %, and INT %. The formula: Rating = ((a + b + c + d) / 6) × 100, where each component is scaled between 0 and 2.375. A "perfect" passer rating is 158.3. The formula was created in 1973 and, despite criticism, remains the official NFL quarterback rating metric.

Passer Rating Benchmarks

158.3: Perfect rating (achieved in single games ~1-2 times per season league-wide). 100+: Elite game (Pro Bowl-level performance). 90-100: Excellent. 80-90: Good. 70-80: Average. Below 70: Poor performance. Career leaders: Aaron Rodgers (~104), Patrick Mahomes (~102). The league average has risen from ~70 in the 1970s to ~88-92 today due to rule changes favoring passing.
