How It Works

This quarterback rating calculator uses established formulas to provide accurate results.

The basic rule:

  • a = ((COMP/ATT) - 0.3) × 5, capped 0 to 2.375
  • b = ((YDS/ATT) - 3) × 0.25, capped 0 to 2.375
  • c = (TD/ATT) × 20, capped 0 to 2.375
  • d = 2.375 - ((INT/ATT) × 25), capped 0 to 2.375
  • Passer Rating = ((a + b + c + d) / 6) × 100

Results are estimates based on standard formulas. Verify with current local data for your specific situation.

Tips & Considerations

  • Double-check your completions before calculating — even small input errors can significantly change your results.
  • Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
  • Pay attention to both passer rating and performance grade — they work together to give you the full picture.
