NFL Passer Rating Calculator
Calculate a quarterback's passer rating using the official NFL formula. Just plug in completions, attempts, yards, touchdowns, and interceptions from any game, season, or career, and get the exact passer rating on the 0 to 158.3 scale.
The NFL passer rating formula was introduced in 1973 by Don Smith of the Pro Football Hall of Fame. It combines four key passing statistics into a single number between 0 and 158.3. A "perfect" passer rating of 158.3 requires hitting the maximum on all four components.
The four components are:
- Completion percentage: (completions / attempts - 0.3) x 5
- Yards per attempt: (yards / attempts - 3) x 0.25
- Touchdown percentage: (touchdowns / attempts) x 20
- Interception percentage: 2.375 - (interceptions / attempts x 25)
Each component is capped between 0 and 2.375. The final rating equals the sum of all four divided by 6, then multiplied by 100.
For context, the average NFL passer rating has hovered around 88-92 in recent seasons. A rating above 100 is considered elite, and only a handful of quarterbacks sustain that over a full career. The all-time career leader is Aaron Rodgers with a 104.5 rating. A perfect 158.3 game requires at least a 77.5% completion rate, 12.5+ yards per attempt, 11.875%+ TD rate, and 0% interceptions.
Note: this is the NFL passer rating, not the newer ESPN QBR (Total Quarterback Rating) which uses a 0-100 scale and incorporates play context.
