How it works
The NFL passer rating condenses a quarterback's passing performance into a single number, and this calculator computes it from the five core passing stats. You enter completions, attempts, passing yards, touchdowns, and interceptions, and it returns the passer rating on the NFL scale. The formula blends four rate components: completion percentage, yards per attempt, touchdown percentage, and interception percentage. Each component is transformed and then capped between 0 and 2.375, so no single category can dominate; the four capped values are averaged and scaled to produce a rating that ranges from 0 to a maximum of 158.3, achieved only with an exceptional line and no interceptions. A rating above 100 is very good, and elite quarterbacks average well over 100 across a season, while ratings in the 70s and 80s are middling and below 70 is poor. Because the components are capped, extreme stat lines are moderated, which is a frequent point of confusion for fans. This is the traditional NFL formula, distinct from the NCAA college formula and from the newer QBR metric. Coaches, analysts, and fans use it to compare quarterbacks and single games. Enter the five passing statistics to compute the passer rating.
Rating = ((a + b + c + d) / 6) × 100, each term capped 0–2.375
The NFL passer rating combines four components: completion percentage, yards per attempt, touchdown percentage, and interception percentage. Each is converted to a scaled value capped between 0 and 2.375, the four are averaged, and the result is multiplied by 100 divided by 6. This produces a rating from 0 to a maximum of 158.3, the so-called perfect rating.

Frequently asked questions
What is passer rating?
Passer rating is a single number summarizing a quarterback's passing performance in the NFL. It combines completion percentage, yards per attempt, touchdown rate, and interception rate into a scale from 0 to a maximum of 158.3. A higher rating means better passing, and it is the traditional standard for comparing quarterbacks.
What is a perfect passer rating?
The maximum possible NFL passer rating is 158.3, often called a perfect rating. Achieving it requires maxing out all four components: a completion percentage of at least 77.5, at least 12.5 yards per attempt, a touchdown rate of at least 11.875 percent, and zero interceptions. Because each component is capped, exceeding these does not raise the rating further.
Why are the components capped?
Each of the four components is limited to a maximum scaled value of 2.375 so that no single category can distort the rating. This prevents an extraordinary figure in one area, such as a very high yards-per-attempt in a small sample, from producing an unrealistic overall rating, keeping the metric balanced across all aspects of passing.
What is a good passer rating?
A rating above 100 is very good, and the best quarterbacks average well over 100 across a season. Ratings in the 90s are solid, the 70s and 80s are average to below average, and under 70 is poor. Context like weather, opponent, and game situation matters, so compare within a season and league.
Is NFL passer rating the same as the college formula?
No. College football uses a different passer efficiency rating with its own weights and no upper cap, so its numbers run on a different scale and can exceed 158.3. This calculator uses the NFL formula. The NFL also has a separate modern metric called Total QBR, which is calculated very differently and is not comparable.
