About Passer Rating

The passer rating is a measure of a quarterback's passing performance, calculated using a formula that takes into account completions, passing yards, touchdown passes, and interceptions.

NFL Passer Rating Formula

The NFL passer rating formula uses four criteria:

  1. Completion percentage (scaled from 0 to 2.375)
  2. Yards per attempt (scaled from 0 to 2.375)
  3. Touchdowns per attempt (scaled from 0 to 2.375)
  4. Interceptions per attempt (scaled from 0 to 2.375)

The formula adds these four values, divides by 6, and multiplies by 100. The maximum possible NFL passer rating is 158.3.

NCAA Passer Rating Formula

The NCAA formula is simpler and produces higher numbers:

  • It adds (8.4 × yards) + (330 × touchdowns) + (100 × completions) - (200 × interceptions)
  • Then divides by attempts
  • The maximum possible NCAA passer rating is 1261.6
