What Is NFL Passer Rating?
NFL passer rating is a statistical measurement of quarterback passing performance based on four passing factors.
The calculation uses completion percentage, yards per pass attempt, touchdown percentage, and interception percentage.
Each factor is converted into a component score. The four components are then combined to produce an overall rating.
The NFL passer rating scale ranges from 0.0 to approximately 158.3.
A perfect NFL passer rating is 158.3 when rounded to one decimal place.
Passer rating does not directly measure rushing production, sacks, game situation, or every aspect of quarterback play.
How Is NFL Passer Rating Calculated?
The NFL formula uses four separate components: completion percentage, yards per attempt, touchdown rate, and interception rate.
Each component is limited to a minimum of zero and a maximum of 2.375.
Component A: Completion Percentage
Divide completions by attempts, subtract 0.3, and multiply by five.
Component B: Passing Yards per Attempt
Divide passing yards by attempts, subtract three, and multiply by 0.25.
Component C: Touchdown Percentage
Divide passing touchdowns by attempts, then multiply by 20.
Component D: Interception Percentage
Divide interceptions by attempts, multiply by 25, and subtract the result from 2.375.
Apply the NFL Component Limits
Each component must be limited to the range from zero through 2.375.
A result below zero becomes zero. A result above 2.375 becomes 2.375.
Final NFL Passer Rating Formula
Add the four adjusted components, divide by six, and multiply by 100.
The result is normally displayed to one decimal place.
NFL Passer Rating Calculation Example
Example: Suppose a quarterback attempts 30 passes, completes 20, throws for 250 yards, records two passing touchdowns, and throws one interception.
Example Quarterback Statistics
- Pass Attempts: 30
- Completions: 20
- Passing Yards: 250
- Touchdown Passes: 2
- Interceptions: 1
Step 1: Calculate Completion Percentage
Divide completions by attempts, then multiply by 100.
The quarterback completed approximately 66.67% of passes.
Step 2: Calculate Component A
Apply the NFL completion component formula.
Step 3: Calculate Component B
Calculate the passing yards component.
Step 4: Calculate Component C
Calculate the passing touchdown component.
Step 5: Calculate Component D
Calculate the interception component.
Step 6: Add the Four Components
The components total approximately 6.0417 before the final NFL rating conversion.
Step 7: Calculate NFL Passer Rating
Divide the component total by six and multiply by 100.
The quarterback’s calculated NFL passer rating is approximately 100.7.
NFL Rating Component Summary
| Rating Component | Example Score |
|---|---|
| Completion | 1.833 |
| Yards per Attempt | 1.333 |
| Touchdowns | 1.333 |
| Interceptions | 1.542 |
| Final NFL Rating | 100.7 |
Each displayed component is rounded for readability. The final rating uses the unrounded component values.
Understanding the NFL Rating Components
Each of the four NFL components evaluates a different part of quarterback passing performance.
Completion Component
This component evaluates the frequency of completed passes relative to attempts.
A higher completion percentage generally increases the component, up to its maximum.
Yardage Component
This component measures passing yards gained per attempt.
More yards per attempt generally produce a higher component score.
Touchdown Component
This component measures passing touchdowns relative to pass attempts.
A higher touchdown rate generally improves the rating.
Interception Component
This component rewards a lower interception rate.
More interceptions relative to attempts reduce the component.
All four components are included in the final NFL passer rating.
What Is a Perfect NFL Passer Rating?
A perfect NFL passer rating is 158.3 when rounded to one decimal place.
The rating reaches this maximum when all four components reach their 2.375 cap.
A perfect rating does not necessarily require completing every attempted pass.
The formula’s maximum component scores are reached with:
- Completion rate: At least 77.5%.
- Passing yards per attempt: At least 12.5.
- Touchdown rate: At least 11.875% of attempts.
- Interception rate: Zero interceptions.
These conditions describe the mathematical formula. They are not a guarantee of winning a football game.
What Is College Passer Efficiency?
College football uses a different formula called passing efficiency.
The college formula uses the same five basic passing statistics:
- Pass Attempts
- Pass Completions
- Passing Yards
- Passing Touchdowns
- Interceptions
However, it assigns different mathematical weights to those statistics compared with the NFL formula.
College passing efficiency does not use the NFL’s four component caps.
As a result, college ratings can exceed the NFL maximum of 158.3.
How Is College Passer Efficiency Calculated?
The NCAA passing efficiency formula multiplies passing yards, touchdowns, and completions by specific weights, subtracts an interception penalty, then divides by total attempts.
In this formula:
- YDS: Passing Yards
- TD: Passing Touchdowns
- COMP: Completions
- INT: Interceptions
- ATT: Pass Attempts
The same recorded passing statistics can produce substantially different NFL and college ratings because the formulas use different scales.
College Passer Efficiency Calculation Example
Example: Use the same quarterback statistics from our NFL rating calculation.
- Attempts: 30
- Completions: 20
- Passing Yards: 250
- Touchdowns: 2
- Interceptions: 1
Step 1: Calculate the Yardage Contribution
Multiply passing yards by 8.4.
Step 2: Calculate the Touchdown Contribution
Multiply passing touchdowns by 330.
Step 3: Calculate the Completion Contribution
Multiply pass completions by 100.
Step 4: Calculate the Interception Penalty
Multiply interceptions by 200.
Step 5: Combine the Weighted Statistics
Add the positive contributions and subtract the interception penalty.
Step 6: Divide by Passing Attempts
Divide the combined value by 30 attempts.
The example college passer efficiency rating is 152.0.
College Passing Efficiency Summary
| Calculation | Weighted Result |
|---|---|
| Passing Yards | 2,100 |
| Touchdown Passes | 660 |
| Completions | 2,000 |
| Interception Penalty | −200 |
| Combined Value | 4,560 |
| College Efficiency | 152.0 |
This example uses the same 30 attempts, 20 completions, 250 passing yards, two touchdowns, and one interception as the NFL example.
NFL Passer Rating vs. College Passer Efficiency
The NFL and college rating systems are different formulas that measure passing efficiency.
They should not be compared as if they use the same scale.
| Feature | NFL | College |
|---|---|---|
| Uses Attempts | Yes | Yes |
| Uses Completions | Yes | Yes |
| Uses Passing Yards | Yes | Yes |
| Uses Passing TDs | Yes | Yes |
| Uses Interceptions | Yes | Yes |
| Component Caps | Yes | No NFL-Style Caps |
| Maximum NFL-Style Rating | 158.3 | Not Applicable |
| Our Example | 100.7 | 152.0 |
Although both systems use the same types of passing statistics, their results have different numerical meanings.
What Is Completion Percentage?
Completion percentage measures the proportion of pass attempts that result in completed passes.
For example, 20 completions from 30 attempts produce:
The quarterback completed approximately two-thirds of the passes attempted.
Completion percentage is one of the four factors used in NFL passer rating.
What Are Yards per Pass Attempt?
Yards per attempt, often abbreviated YPA, measures average passing yards gained for each pass attempt.
For a quarterback with 250 yards on 30 attempts:
The quarterback averaged approximately 8.33 passing yards per attempt.
This is different from yards per completion, which divides passing yards by completions.
What Is Touchdown Percentage?
Touchdown percentage measures how frequently a quarterback throws touchdown passes relative to attempts.
For two touchdowns on 30 attempts:
The touchdown percentage is approximately 6.67%.
What Is Interception Percentage?
Interception percentage measures interceptions thrown relative to the number of pass attempts.
For one interception on 30 attempts:
The interception percentage is approximately 3.33%.
A lower interception rate generally improves the NFL interception rating component.
Quarterback Passing Statistics Summary
The following table summarizes the additional statistics from our 30-attempt example.
| Passing Statistic | Example Result |
|---|---|
| Completions / Attempts | 20 / 30 |
| Completion Percentage | 66.67% |
| Passing Yards | 250 |
| Yards Per Attempt | 8.33 |
| Touchdown Percentage | 6.67% |
| Interception Percentage | 3.33% |
| NFL Passer Rating | 100.7 |
| College Efficiency | 152.0 |
These statistics give additional context beyond the final rating.
Quarterback Passer Rating Comparison Chart
The following table compares three hypothetical quarterback performances.
Each example uses 30 passing attempts.
| Passing Stats | NFL Rating | College Rating |
|---|---|---|
| 18/30, 210 YDS, 1 TD, 2 INT | 64.6 | 116.5 |
| 20/30, 250 YDS, 2 TD, 1 INT | 100.7 | 152.0 |
| 22/30, 280 YDS, 3 TD, 0 INT | 135.4 | 184.7 |
These are mathematical examples using the established rating formulas.
They are not statistics from specific professional or college players.
Notice that improved completion rates, touchdown production, and fewer interceptions can substantially change a quarterback’s passer rating.
What Is a Good NFL Passer Rating?
A higher NFL passer rating generally indicates more efficient passing performance under the formula.
A rating above 100 is often considered a strong passing performance.
However, there is no universal rating threshold that automatically defines a good or bad quarterback.
Interpretation depends on the season, competition, passing volume, and other football circumstances.
A single-game rating can also be more volatile than a season-long rating because it uses fewer passing attempts.
What Is a Good College Passer Efficiency Rating?
College passing efficiency uses a different numerical scale from NFL passer rating.
A college rating around 150 can represent efficient passing performance, but context matters.
The appropriate comparison depends on the college competition, season, opponents, and number of passing attempts.
A college rating of 160 should not be interpreted as equivalent to an NFL rating of 160.
The NFL formula cannot produce a rating above approximately 158.3, while the college formula operates on a different scale.
Does Passer Rating Include Rushing Yards?
No. The traditional NFL passer rating and NCAA passing efficiency formulas are based on passing statistics.
Quarterback rushing yards and rushing touchdowns are not direct inputs.
A mobile quarterback may contribute significantly to a team’s offense through rushing, but those plays are not reflected directly in passer rating.
For a broader player evaluation, consider other offensive statistics in addition to passing efficiency.
Does Passer Rating Include Sacks?
No. Sacks are not direct inputs in either formula used by this calculator.
Traditional passer rating uses pass attempts, completions, passing yards, passing touchdowns, and interceptions.
Sacks can be important when evaluating an offense or quarterback, but they are not a separate passer-rating component.
Other football metrics may account for sacks or broader offensive performance.
Passer Rating vs. ESPN Total QBR
Passer rating and Total QBR are different quarterback metrics.
NFL Passer Rating
Traditional NFL passer rating uses a fixed mathematical formula based on the five official passing statistics.
Its maximum displayed value is 158.3.
Total QBR
ESPN Total QBR is a separate quarterback evaluation metric that considers more aspects of game performance.
It uses a different methodology and is reported on a different numerical scale.
The MyCruncher Passer Rating Calculator calculates traditional NFL passer rating or college passing efficiency, not ESPN Total QBR.
Passer Rating vs. Fantasy Football Points
Passer rating and fantasy football points measure different things.
Passer rating evaluates passing efficiency using a standard formula.
Fantasy football points assign point values to selected game statistics according to league scoring rules.
For example, fantasy football may award points for quarterback rushing yards and rushing touchdowns.
Those statistics are not included directly in traditional NFL passer rating.
To calculate fantasy scoring, use the Fantasy Football Points Calculator .
Can You Calculate a Season Passer Rating?
Yes. The same NFL and college formulas can be applied to a quarterback’s combined passing statistics for an entire season.
Add the season’s passing attempts, completions, yards, touchdowns, and interceptions.
Then apply the selected formula to those combined totals.
Do not simply average individual game passer ratings to obtain the official season rating.
The rating calculated from combined statistics may differ from an average of separate game ratings.
Why Can Small Passing Samples Be Misleading?
A quarterback who attempts only a few passes can produce an unusually high or low rating.
For example, one touchdown on just a few attempts produces a high touchdown percentage.
Likewise, one interception on a small number of attempts creates a relatively large interception rate.
This is why ratings calculated from very small samples should be interpreted carefully.
Season or multi-game statistics often provide additional context.
What If a Quarterback Has Zero Passing Attempts?
Both NFL passer rating and college passing efficiency divide by passing attempts.
If attempts equal zero, the formulas cannot produce a mathematically defined rating.
A zero-attempt stat line should not be treated as automatically equivalent to a true 0.0 passer rating.
At least one official passing attempt is required for these formulas.
How to Check Passing Statistics Before Calculating
Accurate results require consistent and valid statistics.
- Use official attempts. Include the attempts credited to the quarterback in the relevant statistical record.
- Check completions. Completions cannot exceed pass attempts.
- Check touchdown passes. Passing touchdowns must be consistent with the recorded completed passes.
- Check interceptions. Use interceptions thrown rather than interceptions made by the defense.
- Use passing yards. Do not add quarterback rushing yards to the passing yard total.
- Use one consistent period. Do not mix statistics from different games or seasons.
- Verify the rating system. Select NFL or college before calculating.
- Review official corrections. Published player statistics can occasionally change following scoring reviews.
Why Might Passer Rating Differ Between Websites?
Differences may occur when websites use different passing statistics, rating systems, or rounding methods.
For example, the NCAA formula and NFL formula produce different results from the same stat line.
Some services may also display different decimal precision or include updated official statistics.
Check the selected formula and underlying statistics before comparing results.

- Skipping NFL component caps. Each NFL component must remain between zero and 2.375.
- Rounding too early. Intermediate rounding can slightly change the final displayed result.
- Averaging game ratings. Use combined passing statistics for a season rating.
- Using zero attempts. Both formulas require a positive denominator.
- Comparing different scales. A college rating should not be directly compared with an NFL rating.
Frequently Asked Questions
