Passer rating summarises a quarterback’s efficiency. A perfect NFL rating is 158.3; above 100 over a season is excellent. College football uses a different, uncapped efficiency formula.

How it works
Choose the league formula and enter the passing statistics.
Inputs explained
| Field | What to enter |
|---|---|
| Formula | Choose one: NFL / CFL passer rating, NCAA passing efficiency |
| Pass attempts | A number |
| Completions | A number |
| Passing yards | A number |
| Touchdowns | A number |
| Interceptions | A number |
What each result means
- Completion percentage = [Completions]÷[Pass attempts]×100
- Yards per attempt = [Passing yards]÷[Pass attempts]
Example values
How the main result changes when Pass attempts changes and everything else stays at the example values above:
| Pass attempts | Passer rating |
|---|---|
| 15 | 130.6 |
| 22.5 | 124.1 |
| 30 | 100.7 |
| 37.5 | 81 |
| 45 | 67.8 |
| 60 | 51.4 |
Formula
NFL: a = (C/A − 0.3)·5, b = (Y/A − 3)·0.25, c = TD/A·20, d = 2.375 − INT/A·25 (each 0–2.375); rating = (a + b + c + d)/6 × 100
NCAA: (8.4Y + 330TD + 100C − 200INT)/A
Worked example
Inputs: Formula: NFL / CFL passer rating; Pass attempts: 30; Completions: 20; Passing yards: 250; Touchdowns: 2; Interceptions: 1.
Results: Passer rating = 100.7; Completion percentage = 66.7 %; Yards per attempt = 8.33.
