How to Calculate a Quarterback NCAA Passer Rating

Football uses a range of statistics to measure how well a quarterback performs, including the number of yards he throws for, the number of touchdown passes, interceptions and completion percentage. In an attempt to merge all of these statistics into a single number, the NCAA created a passer rating system that uses these statistics to come up with a single number on which quarterbacks can be judged. The formula doesn't take into consideration the number of times the quarterback is sacked or his s rushing performance, and it is not the same as the one used to rate quarterbacks in the NFL.

    • 1

      Multiply the number of yards by 8.4. For example, if the quarterback threw for 300 yards, multiply 8.4 by 300 to get 2,520.

    • 2

      Multiply the number of touchdowns by 330. If the quarterback threw for four touchdowns, multiply 330 by four to get 1,320.

    • 3

      Multiply the number of completions by 100. If the quarterback threw 35 completed passes, multiply 35 by 100 to get 3,500.

    • 4

      Add the results from steps 1 through 3. In this example, you would add 2,520 plus 1,320 plus 3,500 to get 7,340.

    • 5

      Multiply the number of interceptions by 200. For example, if the quarterback threw one interception, multiply 200 by one to get 200.

    • 6

      Subtract the result from Step 5 from the result from Step 4. In this example, you would subtract 200 from 7,340 to get 7,140.

    • 7

      Divide the Step 6 result by the number of passes attempted. Completing the example, if the quarterback threw 55 passes, you would divide 7,140 by 55 to get a passer rating of 129.8.
