Football Passer Rating Calculator (NFL and CFL)

Calculator

115.12

Equation

In Football, passer rating is calculated as follows:

a = ((completions / passing attempts) – 0.3) x 5

b = ((passing yards / passing attempts) – 3) x 0.25

c = (touchdown passes / passing attempts) x 20

d = 2.375 – ((interceptions / passing attempts) x 25)

If any of a, b, c, or d are less than ‘0’, then they calculated as 0.

If any of a,b,c, or d are more than 2.375, then they are calculated as 2.375.

Passer Rating = ((a + b + c + d) / 6) x 100

Example

If a quarterback has made 659 passing attempts and in that time has 450 completions, has passed for 5,477 yards,  made 55 touchdown passes, and has had 10 interceptions, then:

a = ((450 / 659) – 0.3) x 5 = 1.914

b = ((5,477 / 659) – 3) x 0.25 = 1.328

c = (55 / 659) x 20 = 1.669

d = 2.375 – ((10 / 659) x 25) = 1.996

Passer Rating = ((1.914 + 1.328 + 1.669 + 1.996) / 6) x 100

Passer Rating = 115.12

Therefore, the quarterback’s passer rating is 115.12

What is “Passer Rating”?

Passer rating is a tackle football statistic that is used to evaluate a quaterback’s passing performance in both the NFL (National Football League) and the CFL (Canadian Football League). A variation of the formula is used in NCAA football.

It is intended to mix a number of different indicators together into one “aggregate” rating to show a quarterback’s overall passing performance.

History

Passer Rating as a measurement of a quarterback’s effectiveness was implemented in the 1970s.

The system was developed by the NFL’s statistical committee to replace an existing system that ranked a quaterback’s performance relative to their peers.
