About Passer Rating

The passer rating is a measure of a quarterback's passing performance, calculated using a formula that takes into account completions, passing yards, touchdown passes, and interceptions.

NFL Passer Rating Formula

The NFL passer rating formula uses four criteria:

  1. Completion percentage (scaled from 0 to 2.375)
  2. Yards per attempt (scaled from 0 to 2.375)
  3. Touchdowns per attempt (scaled from 0 to 2.375)
  4. Interceptions per attempt (scaled from 0 to 2.375)

The formula adds these four values, divides by 6, and multiplies by 100. The maximum possible NFL passer rating is 158.3.

NCAA Passer Rating Formula

The NCAA formula is simpler and produces higher numbers:

  • It adds (8.4 × yards) + (330 × touchdowns) + (100 × completions) - (200 × interceptions)
  • Then divides by attempts
  • The maximum possible NCAA passer rating is 1261.6

Passer Rating Calculator: Understand a Quarterback’s Efficiency

This Passer Rating Calculator helps you evaluate the performance of a quarterback using official NFL and NCAA formulas. Whether you're a fan, coach, or analyst, this tool breaks down game stats into a single score that reflects how well a QB performed in a game.

NFL Passer Rating Formula:
Rating = ((A + B + C + D) ÷ 6) × 100
Where:
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
NCAA Passer Rating Formula:
Rating = ((8.4 × Yards) + (330 × Touchdowns) + (100 × Completions) - (200 × Interceptions)) ÷ Attempts

FAQ

What is a passer rating?

It’s a numeric value that reflects a quarterback’s passing effectiveness. The higher the number, the better the performance.

Why does the NCAA rating go up to 1261.6 while the NFL max is 158.3?

The two systems use different calculations and scaling. NCAA's formula is broader, which results in larger numbers.

Does this calculator work for both professional and college football?

Yes! You can switch between NFL and NCAA formulas based on which rating type you need.

What if my input values are 0?

Pass attempts must be greater than 0 for the calculation to work. The calculator will prompt you to correct it if needed.

Is this useful for non-technical users?

Absolutely. The interface is simple to use—no technical background required. You get clear stats and visual feedback, much like how the ACFT Calculator or Air Force PT Test Calculator guides military personnel on physical readiness.
