How to use the football passer rating calculator
Prepare the values for this calculation
Calculate the traditional NFL passer rating from attempts, completions, passing yards, touchdown passes and interceptions. Use the formula below to check that it answers your question. Read the input units before transferring figures from a statement, measurement or dataset.
Enter and check each input
- Pass attempts: enter a value at least 1 and no more than 10000 and a whole number. Use the unit named in the label or selected above. Do not leave this required field blank.
- Completions: enter a value at least 0 and no more than 10000 and a whole number. Use the unit named in the label or selected above. Do not leave this required field blank.
- Passing yards: enter a value at least -10000 and no more than 100000. Use the unit named in the label or selected above. Do not leave this required field blank.
- Touchdown passes: enter a value at least 0 and no more than 1000 and a whole number. Use the unit named in the label or selected above. Do not leave this required field blank.
- Interceptions: enter a value at least 0 and no more than 1000 and a whole number. Use the unit named in the label or selected above. Do not leave this required field blank.
The input table gives a complete example. Keep units and time periods consistent across related fields.
Calculate and resolve any input error
Choose Calculate after entering the values. Changes also update the answer after a short pause. If an error appears, follow its message, correct the field and calculate again. Reset restores the example values.
Interpret the answer
Check NFL passer rating first. With the unchanged example inputs, it is 122.5. Compare the additional metrics with the primary result; each has its own label and unit.
Compare and keep a useful result
For a controlled comparison, keep every other example input unchanged and change Pass attempts from 502 to 553. The resulting NFL passer rating is 111.4. This illustrates the equation’s response to that input, rather than a forecast of real events.

Football Passer Rating Calculator formula
Four components based on completion percentage, yards/attempt, TD percentage and interception percentage are each clamped to 0–2.375; rating = (a+b+c+d)/6×100.
Inputs and units
| Input | Format / range | Example |
|---|---|---|
| Pass attempts | minimum 1; maximum 10000; whole number | 502 |
| Completions | minimum 0; maximum 10000; whole number | 343 |
| Passing yards | minimum -10000; maximum 100000 | 4643 |
| Touchdown passes | minimum 0; maximum 1000; whole number | 45 |
| Interceptions | minimum 0; maximum 1000; whole number | 6 |
Worked example
Using the example inputs above, the nfl passer rating is 122.5.
- NFL passer rating
- 122.5
- Completion component
- 1.916335
- Yards/attempt component
- 1.562251
- TD component
- 1.792829
- Interception component
- 2.076195
- Maximum possible
- 158.3
Results and assumptions
This is the NFL passer-rating statistic for passing performance; it is not a complete evaluation of quarterback play.
Sources and method references
Fix an input or unexpected result
Pass attempts is required. Enter pass attempts using the format and bounds in the input table. Zero and an empty field are different: use zero only if it is allowed and represents your data.
If your answer differs from the example, choose Reset and compare every field, including selected units and options. Check percentage versus decimal entry and whether values describe the same period. Round only the final displayed answer when reproducing the formula.
If a discrepancy remains, report the calculator issue with the page address, non-sensitive example inputs, actual result, expected result and a reference for your calculation.
