The NFL Quarterback Rating Calculator calculates the traditional NFL passer rating using completions, passing attempts, passing yards, touchdown passes, and interceptions. Enter a quarterback's passing statistics to calculate passer rating, completion percentage, yards per attempt, touchdown percentage, interception percentage, and the four rating components.

NFL Passer Rating Result
The quarterback completed 25 of 35 passes for 280 yards, 2 touchdowns, and 1 interception, producing a traditional NFL passer rating of 102.08.
The traditional NFL passer rating uses four passing components: completion percentage, yards per attempt, touchdown percentage, and interception percentage. Each component is limited to a maximum of 2.375 and a minimum of 0.
What Is an NFL Quarterback Rating?
The NFL passer rating is the traditional statistical rating used to summarize a quarterback's passing performance. It is calculated from four passing factors:
- Completion percentage
- Passing yards per attempt
- Touchdown percentage
- Interception percentage
Although people often call it a "quarterback rating," the more precise statistical name is passer rating. The traditional NFL formula produces a rating from 0.0 to 158.3.
How the NFL Passer Rating Formula Works
The traditional formula converts four passing statistics into four separate components. The components are then added together and converted into the final passer rating.
The four components are:
- Completion component: based on completion percentage.
- Yards-per-attempt component: based on passing yards per attempt.
- Touchdown component: based on touchdown passes per attempt.
- Interception component: based on interceptions per attempt.
NFL Passer Rating Formula
The traditional NFL formula uses these calculations:
Component A:
((Completions ÷ Attempts) × 100 − 30) × 0.05
Component B:
((Passing Yards ÷ Attempts) − 3) × 0.25
Component C:
((Touchdown Passes ÷ Attempts) × 100) × 0.20
Component D:
2.375 − ((Interceptions ÷ Attempts) × 100 × 0.25)
Each component is restricted to a range from 0 to 2.375.
The final rating is:
((A + B + C + D) ÷ 6) × 100
This produces the traditional NFL passer rating, with a maximum of 158.3.
1. Completion Percentage Component
The first component measures how frequently the quarterback completes his pass attempts.
The calculation starts with completion percentage and applies the NFL formula:
(Completion Percentage − 30) × 0.05
The resulting component cannot be below 0 or above 2.375.
2. Yards Per Attempt Component
The second component measures how many passing yards a quarterback gains per pass attempt.
It is calculated as:
(Yards Per Attempt − 3) × 0.25
Like the other components, the result is capped between 0 and 2.375.
3. Touchdown Percentage Component
The third component measures touchdown passes relative to total passing attempts.
The formula is:
Touchdown Percentage × 0.20
A higher touchdown rate increases this component, subject to the 2.375 maximum.
4. Interception Percentage Component
The fourth component measures the percentage of pass attempts that result in interceptions.
The formula starts with:
2.375 − (Interception Percentage × 0.25)
A higher interception percentage reduces this component. The result cannot be lower than 0 or higher than 2.375.
Why Are the Components Capped?
The traditional NFL passer-rating formula limits each component to the range of 0 to 2.375. These limits prevent one unusually high or low statistical category from having unlimited influence on the final rating.
Because all four components have the same maximum, the highest possible traditional passer rating is 158.3.
Example NFL Quarterback Rating Calculation
Suppose a quarterback records the following statistics:
- 25 completions
- 35 passing attempts
- 280 passing yards
- 2 touchdown passes
- 1 interception
Completion percentage:
25 ÷ 35 × 100 = 71.43%
Yards per attempt:
280 ÷ 35 = 8.00
Touchdown percentage:
2 ÷ 35 × 100 = 5.71%
Interception percentage:
1 ÷ 35 × 100 = 2.86%
The four capped components are approximately:
- Completion component = 2.07
- Yards-per-attempt component = 1.25
- Touchdown component = 1.14
- Interception component = 1.66
Therefore:
((2.07 + 1.25 + 1.14 + 1.66) ÷ 6) × 100 ≈ 102.08
The traditional NFL passer rating is therefore approximately 102.08.
What Is a Perfect NFL Passer Rating?
The maximum traditional NFL passer rating is 158.3.
A quarterback reaches the maximum when all four passer-rating components reach their maximum value of 2.375.
A rating of 158.3 does not mean the quarterback completed every pass. It means the four statistical components have reached the maximum values permitted by the traditional passer-rating formula.
Can NFL Passer Rating Be Higher Than 158.3?
No. The traditional NFL passer-rating formula is capped at 158.3.
Even if a quarterback's individual statistics would produce a component above 2.375, that component is limited to 2.375 before the final rating is calculated.
Can NFL Passer Rating Be 0.0?
Yes. The traditional formula allows a passer rating of 0.0 when all four components are limited to their minimum value of zero.
This does not mean the quarterback necessarily completed zero passes. It means the combination of passing statistics produces the minimum value under the traditional formula.
Does Passer Rating Include Rushing?
No. Traditional NFL passer rating is based on passing statistics. Rushing yards, rushing touchdowns, rushing attempts, and other rushing statistics are not directly included in the formula.
A quarterback can therefore have a strong overall offensive game while having a lower traditional passer rating if his passing statistics are less efficient.
Does Passer Rating Include Sacks?
Sacks are not entered separately into the traditional passer-rating calculation used by this calculator. The calculator uses passing attempts, completions, passing yards, touchdown passes, and interceptions.
Because the traditional passer-rating formula is specifically based on those passing statistics, this calculator does not add a separate sack input.
NFL Passer Rating vs. QBR
Passer rating and QBR are different statistics.
The traditional passer rating is calculated from the four statistical components described above. QBR is a separate quarterback evaluation statistic with a different methodology.
Therefore, a quarterback can have a particular passer rating and a different QBR for the same game.
Can This Calculator Be Used for One Game?
Yes. You can enter a quarterback's statistics from a single NFL game to calculate the traditional passer rating for that performance.
For example, enter the quarterback's completions, attempts, passing yards, touchdown passes, and interceptions from the game.
Can This Calculator Be Used for a Full Season?
Yes. You can use season totals for completions, attempts, passing yards, touchdown passes, and interceptions.
The resulting number represents the traditional passer rating calculated from those aggregate statistics.
When comparing seasons, make sure the statistics are calculated using the same statistical scope and definitions.
Why Use an NFL Quarterback Rating Calculator?
Calculating passer rating manually requires several intermediate calculations and component limits. A calculator reduces the amount of arithmetic required.
This tool can be useful for:
- Checking a quarterback's game statistics
- Calculating season passer ratings
- Understanding how passing statistics affect rating
- Comparing passing performances using the same formula
- Learning how the traditional NFL passer-rating formula works
- Checking manually calculated passer-rating results
