How the NFL Passer Rating Calculator works
The NFL formula scores four parts per attempt: completion rate, yards, touchdowns and interceptions. Each part is capped between 0 and 2.375.
The four parts are added, divided by 6 and multiplied by 100. A perfect rating is 158.3. College football uses a different formula.
The formula
Worked example
Using the default values shown in the calculator:
| Pass attempts | 35 |
|---|---|
| Completions | 24 |
| Passing yards | 285 |
| Touchdown passes | 2 |
| Interceptions | 1 |
- Parts: a = 1.929, b = 1.286, c = 1.143, d = 1.661.
- Rating = (1.929 + 1.286 + 1.143 + 1.661) ÷ 6 × 100 = 100.3.
Result:
| Passer rating | 100.3 |
|---|---|
| Completion % | 68.6% |
| Yards per attempt | 8.14 |
| Completion component | 1.929 |
| Yards component | 1.286 |
| Touchdown component | 1.143 |
| Interception component | 1.661 |

Over a season, around 90 to 95 is roughly league average in recent NFL seasons, and above 100 is very good.
Why is the maximum 158.3?
Each of the four parts is capped at 2.375, and 4 × 2.375 ÷ 6 × 100 = 158.3.
