American Football Passer Rating Calculator (NFL and CFL)

When it comes to evaluating the performance of quarterbacks in American football, the passer rating is a crucial metric that provides insight into their effectiveness on the field. The passer rating system, used in both the National Football League (NFL) and the Canadian Football League (CFL), takes into account various statistical factors to determine a quarterback's overall performance. This article will delve into the details of the passer rating formula and introduce an interactive calculator to help you determine the passer rating for any quarterback.

Understanding the Passer Rating Formula

The passer rating formula is a complex equation that considers a quarterback's completion percentage, yards per attempt, touchdown percentage, and interception percentage. These factors are combined to calculate a passer rating, which provides a numerical value representing a quarterback's efficiency.

Passer Rating Formula:
Passer Rating = ((a + b + c + d) / 6) * 100

The four components of the formula are:

  • a - Completion Percentage Factor
    a = ((Completions / Attempts) - 0.3) * 5
  • b - Yards per Attempt Factor
    b = ((Yards / Attempts) - 3) * 0.25
  • c - Touchdown Percentage Factor
    c = (Touchdowns / Attempts) * 20
  • d - Interception Percentage Factor
    d = 2.375 - ((Interceptions / Attempts) * 25)
