How are the QBR ratings calculated in the NFL? The QBR (passer rating) ranges from 0 to 158.3.

0 is absolutely awful, and 158.3 is unbelievably good (and quite rare).

Negative numbers aren't possible with the QBR scoring system, as all negative numbers are rounded up to zero.


In order to achieve a 0 QBR rating, quarterbacks need to do ALL of these things in a single game:

1. Post a completion percentage of 30.0% or less

2. Average no more than 3.0 yards per attempt

3. Throw for no touchdowns

4. Have an interception/attempt percentage of no lower than 9.5%

In order to score a 0 QBR rating, Quarterbacks need to do all of these things.


Let's take a look at an example of a 0.0 QBR game, which was posted by Atlanta quarterback Josh Rosen on November 14th, 2021.

In the game, Rosen posted this stat line:

14 yards
0 Touchdowns
1 Interception

Rosen posted a completion percentage of 16.6%.

Rosen averaged 2.3 yards per attempt (6 total attempts).

Rosen threw for 0 touchdowns.

Rosen threw for 1 interception.

Add all of that up and you have a 0.0 game.


Some of the best quarterbacks in the history of the game have had terrible days where they posted a 0.0 QBR rating.

This list includes Terry Bradshaw, Warren Moon and Peyton Manning.
