What is the passer rating?
Type a quarterback’s completions, attempts, passing yards, touchdown passes and interceptions. The passer rating calculator gives the NFL passer rating with each of its four parts, and the NCAA passing efficiency.

NFL passer rating: 121.1. With 336 of 497 for 4,557 yards, 49 TD and 10 INT, the passer rating is 121.1.
How to calculate
Works out a quarterback’s NFL passer rating from completions, attempts, yards, touchdowns and interceptions, with each of the four parts and the NCAA passing efficiency.
Example with the default inputs (Pass attempts 497, Completions 336, Passing yards 4,557, Touchdown passes 49, Interceptions 10): With 336 of 497 for 4,557 yards, 49 TD and 10 INT, the passer rating is 121.1.
Method: a = (comp ÷ att − 0.3) × 5; b = (yds ÷ att − 3) × 0.25; c = td ÷ att × 20; d = 2.375 − int ÷ att × 25; each held to 0 to 2.375; rating = (a + b + c + d) ÷ 6 × 100. NCAA = (8.4 × yds + 330 × td + 100 × comp − 200 × int) ÷ att.
- The totals are for any span: a game, a season or a career.
- Touchdown passes are completions, and interceptions are incomplete passes, so td ≤ completions and int ≤ attempts − completions.
- The NFL rating is shown to one decimal, as the league publishes it.

- Pass attempts 497, Completions 336, Passing yards 4,557, Touchdown passes 49, Interceptions 10 gives NFL passer rating 121.105801, Completion part 1.880282, Yards part 1.542254, Touchdown part 1.971831, Interception part 1.871982, NCAA passing efficiency 173.136419.Source: Pro Football Reference, 2004 Indianapolis Colts statistics (Peyton Manning: 336 of 497, 4,557 yards, 49 TD, 10 INT, rating 121.1), https://www.pro-football-reference.com/teams/clt/2004.htm (retrieved 2026-10-05) (rating 121.1); Wikipedia, Passer rating (NFL and NCAA formulas; each NFL part is held between 0 and 2.375; a perfect NFL rating is 158.3), https://en.wikipedia.org/wiki/Passer_rating (retrieved 2026-10-05)
- Pass attempts 20, Completions 20, Passing yards 500, Touchdown passes 6, Interceptions 0 gives NFL passer rating 158.333333, Completion part 2.375, Yards part 2.375, Touchdown part 2.375, Interception part 2.375, NCAA passing efficiency 409.Source: Wikipedia, Passer rating (NFL and NCAA formulas; each NFL part is held between 0 and 2.375; a perfect NFL rating is 158.3), https://en.wikipedia.org/wiki/Passer_rating (retrieved 2026-10-05) (perfect rating 158.3)
- Pass attempts 10, Completions 2, Passing yards 10, Touchdown passes 0, Interceptions 4 gives NFL passer rating 0, Completion part 0, Yards part 0, Touchdown part 0, Interception part 0, NCAA passing efficiency -51.6.Source: Wikipedia, Passer rating (NFL and NCAA formulas; each NFL part is held between 0 and 2.375; a perfect NFL rating is 158.3), https://en.wikipedia.org/wiki/Passer_rating (retrieved 2026-10-05)
How it works
All five inputs are whole numbers. The maths is exact; only the display rounds.
NFL passer rating. With attempts att, completions comp, passing yards yds, touchdown passes td and interceptions int:
- a = (comp ÷ att − 0.3) × 5
- b = (yds ÷ att − 3) × 0.25
- c = td ÷ att × 20
- d = 2.375 − int ÷ att × 25
Each part is then held between 0 and 2.375: a value below 0 becomes 0 and a value above 2.375 becomes 2.375. The rating is (a + b + c + d) ÷ 6 × 100, from 0 to 158.33 (shown to one decimal).
NCAA passing efficiency = (8.4 × yds + 330 × td + 100 × comp − 200 × int) ÷ att, with no limits.
Completion rate = comp ÷ att × 100%.
Rules
- Attempts are at least 1. Completions are at most attempts. Touchdown passes are at most completions. Interceptions are at most attempts − completions. Inputs that break a rule give no answer.
- Yards may be below 0 (a season of short losses).
Worked examples by hand
Peyton Manning, 2004: 336 of 497, 4,557 yards, 49 TD, 10 INT. a = (336 ÷ 497 − 0.3) × 5 = 1.8803; b = (4,557 ÷ 497 − 3) × 0.25 = 1.5423; c = 49 ÷ 497 × 20 = 1.9718; d = 2.375 − 10 ÷ 497 × 25 = 1.8720. The sum is 7.2664; ÷ 6 × 100 = 121.1. NCAA: (8.4 × 4,557 + 330 × 49 + 100 × 336 − 200 × 10) ÷ 497 = 86,048.8 ÷ 497 = 173.1.
A perfect game: 20 of 20, 500 yards, 6 TD, 0 INT. a = 3.5, b = 5.5, c = 6 and d = 2.375 are all held at 2.375, so the rating is 4 × 2.375 ÷ 6 × 100 = 158.3. NCAA: (4,200 + 1,980 + 2,000) ÷ 20 = 409.
2 of 10, 10 yards, 0 TD, 4 INT. a = −0.5, b = −0.5, c = 0 and d = −7.625 are all held at 0, so the rating is 0. NCAA: (84 + 0 + 200 − 800) ÷ 10 = −51.6.
Other questions people ask
What is the NFL passer rating formula?
Four parts, each held between 0 and 2.375: a = (completions ÷ attempts − 0.3) × 5, b = (yards ÷ attempts − 3) × 0.25, c = touchdowns ÷ attempts × 20 and d = 2.375 − interceptions ÷ attempts × 25. The rating is (a + b + c + d) ÷ 6 × 100.
What is a perfect passer rating?
158.3. It needs every part at its 2.375 cap: a completion rate of 77.5% or more, 12.5 yards an attempt or more, touchdowns on 11.875% of attempts or more, and no interceptions.
Can a passer rating be 0?
Yes. Each part stops at 0, so the lowest rating is 0. It happens with a completion rate of 30% or less, 3 yards an attempt or less, no touchdowns and interceptions on 9.5% of attempts or more.
How is the NCAA passer rating different?
College football uses passing efficiency: (8.4 × yards + 330 × touchdowns + 100 × completions − 200 × interceptions) ÷ attempts. It has no caps, so it can go below 0 or above 1,000.
What is a good passer rating?
In recent NFL seasons the league average has been in the 90s. A rating above 100 over a season is very good; Peyton Manning’s 49-touchdown 2004 season rated 121.1.
Does the passer rating count rushing or sacks?
No. It uses only passing: attempts, completions, passing yards, touchdown passes and interceptions. Sacks and runs are not in it.
