NFL Passer Rating Calculator
Named NFL passer rating actual completion/yard/TD/interception components clipped independently to [0,2.375]; not NCAA formula, QBR, rushing contribution or outcome prediction.
Description
NFL passer rating clips four passing components independently.
NFL passer rating clips four passing components independently. It differs from QBR and NCAA scoring.1
The returned values include Nfl component scores, Nfl passer rating. The How section below explains the calculation, input rules and interpretation.
When to use NFL Passer Rating Calculator
Use NFL Passer Rating Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No rushing contribution, NCAA formula or outcome prediction is supplied.
Prepare the observed race, match or training records and the stated units. Supply independently verified rule editions, calibration tables and targets where requested.
How to use NFL Passer Rating Calculator and understand its results
- Prepare the observed race, match or training records and the stated units. Supply independently verified rule editions, calibration tables and targets where requested.
- Enter observedPassAttempts, observedCompletions, observedPassingYards, observedPassingTouchdowns, observedInterceptions using the field table and calculation rules, then run the tool.
- Read nflComponentScores, nflPasserRating. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| observedPassAttempts | Observed pass attempts | number | Required |
| observedCompletions | Observed completions | number | Required |
| observedPassingYards | Observed passing yards | number | Required |
| observedPassingTouchdowns | Observed passing touchdowns | number | Required |
| observedInterceptions | Observed interceptions | number | Required |
Enter integer attempts 1–1000000, completions 0–attempts, TD 0–completions, interceptions 0–attempts−completions and signed integer yards bounded±1000000. Clip each component 0–2.375; return components and rating.
components=clip((C/A−.3)5,(Y/A−3).25,(TD/A)20,2.375−(INT/A)25); rating=100sum/6 Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

}Limitations and assumptions
No rushing contribution, NCAA formula or outcome prediction is supplied.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Basketball True Shooting % Calculator: True shooting estimates points per two shot-attempt equivalents. Free-throw weighting is an explicit approximation. For a complementary task, use Basketball Pace Possession Estimate: A possession estimate combines field goals, weighted free throws, offensive rebounds and turnovers. Pace averages team/opponent estimates before time normalization.
