QB Passer Rating Calculator
Calculate the NFL's official passer rating from completions, attempts, yards, touchdowns, and interceptions.
Informational only — not a substitute for official league statistics or professional judgment.
How it's calculated
Assumptions
- Uses the NFL's official four-component formula — the same one used for college and high school passer rating, though some leagues use a different formula (NCAA's own "passing efficiency" rating is calculated differently and not covered by this tool).
- All four components are clamped to 0–2.375 per the official rule, so an extreme single-game stat line can't push the rating outside its normal bounds.

Frequently asked questions
What's the highest possible passer rating?
158.3 is the maximum under the NFL's formula — reached when a quarterback's completion rate, yards per attempt, touchdown rate, and interception rate all hit or exceed the thresholds that cap each of the four components at their maximum value.
Is passer rating the same as QBR?
No. Passer rating (calculated here) uses only the four official box-score inputs — completions, attempts, yards, touchdowns, and interceptions. ESPN's Total QBR is a separate, proprietary metric that also weighs sacks, rushing, fumbles, and situational context (down, distance, game score), and isn't publicly reproducible from a simple formula.
Why is passer rating capped between 0 and 158.3?
Each of the four components in the formula is individually clamped to a 0–2.375 range before being averaged. This prevents one extreme game (e.g. a huge per-attempt yardage outlier) from producing a nonsensical, unbounded rating.
Does passer rating account for sacks or rushing yards?
No — the official formula only uses passing completions, attempts, yards, touchdowns, and interceptions. Sacks, rushing production, and fumbles are excluded, which is one of the main criticisms of the stat and part of why ESPN built QBR as an alternative.
