What Is NFL Passer Rating?

NFL passer rating is a traditional statistic designed to measure certain aspects of a quarterback's passing performance. The formula combines completion percentage, passing yards per attempt, touchdown percentage, and interception percentage into a single rating.

The traditional NFL passer rating scale ranges from 0.0 to 158.3. A higher rating generally indicates stronger passing efficiency according to the formula.

The statistic is useful because it combines multiple passing measurements into one number. However, passer rating does not measure every part of quarterback play, so it is often considered alongside other statistics.

How Is NFL Passer Rating Calculated?

The traditional NFL passer rating formula uses four separate components. These components are calculated from the quarterback's completions, attempts, passing yards, touchdown passes, and interceptions.

The four traditional passer rating components are:
  • Completion percentage component
  • Yards per attempt component
  • Touchdown percentage component
  • Interception percentage component

Each component is limited to a minimum of 0 and a maximum of 2.375. The four limited components are then combined to calculate the final passer rating.

NFL Passer Rating Formula

The traditional formula uses four components commonly represented as A, B, C, and D.

Component A: Completion Percentage

A = ((Completions ÷ Attempts) − 0.3) × 5

Component B: Yards Per Attempt

B = ((Passing Yards ÷ Attempts) − 3) × 0.25

Component C: Touchdown Percentage

C = (Touchdown Passes ÷ Attempts) × 20

Component D: Interception Percentage

D = 2.375 − ((Interceptions ÷ Attempts) × 25)

After calculating the four components, each one is limited to a minimum of 0 and a maximum of 2.375.

Final NFL Passer Rating Formula

Passer Rating = ((A + B + C + D) ÷ 6) × 100

What Is a Perfect NFL Passer Rating?

A perfect traditional NFL passer rating is 158.3.

The maximum exists because each of the four components in the formula is capped at 2.375. Once all four components reach their maximum value, the final passer rating reaches 158.3.

A quarterback can produce statistics beyond the thresholds needed for a perfect rating, but the formula's component limits prevent the final traditional passer rating from exceeding 158.3.

What Statistics Do You Need to Calculate Passer Rating?

You need five passing statistics to calculate traditional NFL passer rating:

  • Completions
  • Passing attempts
  • Passing yards
  • Touchdown passes
  • Interceptions

The calculator uses these five statistics to calculate the four components of the formula and then combines them into the final passer rating.

NFL Passer Rating Example

Suppose a quarterback records the following passing statistics:

Statistic Value
Completions 25
Passing Attempts 35
Passing Yards 280
Touchdown Passes 2
Interceptions 1

The calculator first determines the completion percentage and yards per attempt. It then calculates the touchdown percentage and interception percentage.

Next, the calculator applies the traditional passer rating formula to determine the four components. Each component is limited to the allowed range before the final rating is calculated.

  4. Enter the number of touchdown passes.
  5. Enter the number of interceptions.
  6. Select Calculate Passer Rating.
  7. Review the final rating and supporting passing statistics.

What Does NFL Passer Rating Measure?

Traditional NFL passer rating measures four areas of passing efficiency.

Measurement What It Represents
Completion Percentage How often the quarterback completed a pass.
Yards Per Attempt The average number of passing yards gained per attempt.
Touchdown Percentage The percentage of passing attempts that resulted in touchdowns.
Interception Percentage The percentage of passing attempts that resulted in interceptions.

What Does NFL Passer Rating Not Measure?

Passer rating is useful, but it does not measure every aspect of quarterback performance.

For example, traditional passer rating does not directly include:

  • Rushing yards
  • Rushing touchdowns
  • Sacks
  • Fumbles
  • Opponent strength
  • Dropped passes
  • Game situation
  • Difficulty of individual throws
  • Defensive pressure

Because of these limitations, passer rating is generally more useful when viewed together with other quarterback statistics.

Passer Rating vs. Completion Percentage

Completion percentage and passer rating are related, but they are not the same statistic.

Completion percentage measures how often a quarterback completed a pass. Passer rating includes completion percentage as one part of a larger formula.

Statistic Description
Completion Percentage Measures the percentage of passes completed.
Yards Per Attempt Measures average passing yards gained per attempt.
NFL Passer Rating Combines four passing-efficiency components into one rating.

How to Interpret NFL Passer Rating

A higher passer rating generally represents better passing efficiency according to the traditional formula. However, there is no single rating that guarantees a quarterback played better in every situation.

Passer Rating General Interpretation
100 or higher Strong passing efficiency
90 to 99.9 Very good passing efficiency
80 to 89.9 Solid passing efficiency
70 to 79.9 Moderate passing efficiency
Below 70 Lower passing efficiency according to the traditional formula

These ranges are general descriptions rather than official NFL performance classifications.

Why Is NFL Passer Rating Capped at 158.3?

The traditional NFL passer rating formula limits each of its four components to a maximum value of 2.375.

When all four components reach that maximum, the formula produces a final rating of 158.3. This is why traditional NFL passer rating cannot exceed that number.

Can You Calculate Passer Rating for One Game?

Yes. You can calculate passer rating for a single game by entering the quarterback's statistics from that game.

The same formula can also be used for a season or another group of games as long as you use the total completions, attempts, passing yards, touchdown passes, and interceptions for the period you want to analyze.

Can Passer Rating Be 0?

Yes. The traditional formula has a minimum possible rating of 0.0.

The formula limits each component to a minimum of zero. In an extremely poor passing-statistics scenario, all four components can reach their minimum value, producing a passer rating of 0.0.

Related NFL Statistics

Passer rating is only one way to evaluate a quarterback's passing performance. Other useful statistics can include:

  • Completion percentage
  • Passing yards
  • Passing yards per attempt
  • Touchdown passes
  • Interceptions
  • Touchdown-to-interception ratio
  • Quarterback rating
  • Net yards per passing attempt

Looking at multiple statistics can provide a broader view of a quarterback's performance than relying on a single number.
