What is the formula for NFL passer rating?

Four components are calculated: (a) completions/attempts minus 0.3, times 5; (b) yards/attempts minus 3, times 0.25; (c) touchdowns/attempts, times 20; (d) 2.375 minus interceptions/attempts times 25. Each is clamped between 0 and 2.375, the four are summed, divided by 6, then multiplied by 100.

What is the maximum possible passer rating?

A perfect game caps the rating at 158.3. This happens when all four components hit their 2.375 maximum, which requires a high completion rate, strong yards per attempt, a touchdown on a large share of attempts, and zero interceptions.

Why is my rating different from what I saw on a broadcast?

Broadcasts sometimes round intermediate stats or use a season-to-date stat line instead of single-game numbers. Double-check you are using the exact completions, attempts, yards, touchdowns, and interceptions for the game or period being rated.

Does passer rating account for rushing yards or sacks?

No. The official NFL passer rating formula only uses passing attempts, completions, passing yards, touchdown passes, and interceptions. Rushing stats and sacks do not affect it.

Is this the same as ESPN Total QBR?

No. Passer rating (sometimes called the NFL "QB rating") is the older four-component formula described above. Total QBR is a separate, more complex metric from ESPN that weighs game situation and is not calculated the same way.

Can passer rating be negative?

No. Each component is clamped to a minimum of 0, so the lowest possible passer rating is 0.0, even with many interceptions and no completions.

How it works

Enter pass attempts, completions, passing yards, touchdowns, and interceptions.
Each of the four rating components is computed from those stats.
Every component is clamped to a minimum of 0 and a maximum of 2.375.
The four clamped components are summed, divided by 6, and multiplied by 100.
The result is the passer rating, shown with each component value for reference.
