College Football Passer Rating Calculator (NCAA)

This calculator works out the college (NCAA) passing efficiency rating. Enter pass attempts, completions, passing yards, touchdown passes and interceptions; you get the rating and the completion percentage.

Formula

NCAA rating = (8.4 × yards + 330 × touchdowns + 100 × completions − 200 × interceptions) ÷ attempts.

This is the NCAA passing efficiency formula from the NCAA football statistics manual. The NFL uses a different formula capped at 158.3.

Worked Example

20 of 30, 250 yards, 2 touchdowns, 1 interception.

1. 8.4 × 250 = 2,100
2. 330 × 2 = 660
3. 100 × 20 = 2,000
4. −200 × 1 = −200
5. Rating = 4,560 ÷ 30 = 152.0
6. Completion percentage = 20 ÷ 30 = 66.7%

How to read the result

An NCAA rating around 130-140 is roughly average for a season; above 160 is outstanding. The college formula has no cap, so short games with few attempts can give extreme values.

Limits and common mistakes

• Completions cannot exceed attempts; the calculator shows Cannot compute.
• Do not mix this with the NFL passer rating; the numbers are on different scales.
