Frequently asked questions
How is NFL passer rating calculated?
It uses four components: completion percentage, yards per attempt, touchdown rate and interception rate. Each is scaled and clamped to a range of 0 to 2.375. The rating is the sum of the four divided by 6, times 100.
What is a perfect passer rating?
A perfect rating is 158.3, which happens when all four components reach their 2.375 ceiling. That requires a completion percentage of 77.5 or higher, at least 12.5 yards per attempt, a touchdown on at least 11.875 percent of attempts and zero interceptions.
Why are the components clamped?
Each of the four parts is limited to a maximum of 2.375 and a minimum of 0. This caps the reward for any single category, so a quarterback cannot offset many interceptions with an extreme number in another stat.
Is this the same as the NFL quarterback rating on TV?
Yes. This is the traditional NFL passer rating shown in broadcasts and box scores. It is different from ESPN's Total QBR, which is a separate proprietary metric on a 0 to 100 scale.
What counts as a good passer rating?
Roughly speaking, a rating near 90 is solid, above 100 is very good and above 110 over a full season is elite. League average has drifted upward over time as passing offenses have improved.
