Passer Rating Calculator
Calculate NFL passer rating and NCAA passing efficiency for any quarterback. Enter attempts, completions, yards, touchdowns, and interceptions for instant QB rating results with charts.
About This Calculator
Passer rating, also called quarterback rating, is a statistical metric used in American and Canadian football to evaluate a quarterback's passing efficiency. This calculator supports both the NFL passer rating formula (0-to-158.3 scale) and the NCAA passing efficiency formula used in college football. It is essential for football analysts, coaches, fantasy football players, sports journalists, and fans who want to measure quarterback performance beyond basic stats.
The NFL passer rating combines four passing statistics into a single score: completion percentage, yards per attempt, touchdown percentage, and interception percentage. Each component is calculated using a specific formula and capped between 0 and 2.375 to create a fair scale. The final rating is the sum of the four components divided by 6 and multiplied by 100, resulting in a scale from 0 (poor) to 158.3 (perfect). The NCAA uses a different formula with a linear calculation that places more weight on yards and touchdowns, producing ratings on a much wider scale.
The component breakdown chart shows how each of the four formula elements contributes to the final NFL rating. The comparison chart displays both NFL and NCAA ratings side by side. Understanding these components helps quarterbacks identify areas for improvement — whether it is completing more passes, gaining more yards per attempt, increasing touchdown rate, or reducing interceptions.
To use this calculator, enter the quarterback's pass attempts, completions, passing yards, touchdowns, and interceptions from any game, season, or career. The calculator instantly computes both the NFL passer rating (on the familiar 0-to-158.3 scale) and the NCAA passing efficiency rating. The results section also displays key rate stats — completion percentage, yards per attempt, touchdown percentage, and interception percentage — giving you a complete picture of passing performance at a glance.
Frequently Asked Questions
What is passer rating in football?
Passer rating, also known as quarterback rating, is a statistical metric used in American and Canadian football to evaluate a quarterback's passing performance. The NFL rating uses a 0-to-158.3 scale based on completion percentage, yards per attempt, touchdown percentage, and interception percentage.
How is NFL passer rating calculated?
NFL passer rating is calculated using four components: a = ((completions/attempts) − 0.3) × 5, b = ((yards/attempts) − 3) × 0.25, c = (touchdowns/attempts) × 20, d = 2.375 − ((interceptions/attempts) × 25). Each component is capped between 0 and 2.375. The final rating = ((a + b + c + d) / 6) × 100.
What is the NCAA passing efficiency formula?
The NCAA (college football) passing efficiency formula is different from the NFL: Passer Rating = ((8.4 × passing yards) + (330 × touchdowns) + (100 × completions) − (200 × interceptions)) / pass attempts. The NCAA scale ranges from approximately −731 to 1,261, with the average NCAA quarterback posting around 130-150.
What is a good passer rating in the NFL?
In the NFL, a passer rating below 70 is poor, 70-85 is below average, 85-95 is average, 95-105 is above average, and anything above 105 is excellent. A rating above 110 is considered elite. The highest career passer rating in NFL history belongs to Aaron Rodgers at 103.1.
What is a perfect passer rating (158.3)?
A perfect passer rating of 158.3 requires a quarterback to achieve minimum 77.5% completion rate, at least 12.5 yards per attempt, a touchdown on at least 11.875% of attempts, and zero interceptions. No NFL quarterback has ever achieved a perfect career rating, but several have posted perfect single-game ratings.
Who has the highest passer rating in NFL history?
Aaron Rodgers holds the highest career passer rating in NFL history at 103.1 (minimum 1,500 attempts). Other quarterbacks with top career ratings include Russell Wilson (100.0), Joe Burrow (99.3), Patrick Mahomes (99.0), and Lamar Jackson (98.0). Tom Brady finished his career at 97.2.
What is the difference between NFL and NCAA passer rating?
The NFL passer rating uses a 0-to-158.3 scale with four components capped at 2.375 each, while the NCAA formula uses a simpler linear equation with no upper cap and can produce ratings from −731 to over 1,261. The NCAA formula places more weight on yards per attempt and touchdowns, while the NFL formula balances all four passing categories evenly.
Can passer rating be negative?
The NFL passer rating has a minimum of 0, so it cannot go negative. However, the NCAA passing efficiency formula can produce negative ratings if a quarterback throws many interceptions with a low completion percentage and few yards per attempt on a high number of attempts.
