Enter a quarterback's completions, attempts, passing yards, touchdowns, and interceptions to calculate the official NFL Passer Rating (QBR). You'll get the final QB Rating out of a perfect 158.3, plus a breakdown of all four component ratings so you can see exactly how the score is built.

Passer Rating, also called QB Rating or QBR, is the official NFL metric used to evaluate a quarterback's passing performance. It combines completion percentage, yards per attempt, touchdown percentage, and interception percentage into a single number on a scale from 0 to a perfect 158.3.
The formula uses four components, each capped between 0 and 2.375: (1) completion percentage component = ((comp/att) - 0.3) × 5, (2) yards-per-attempt component = ((yards/att) - 3) × 0.25, (3) touchdown % component = (TD/att) × 20, and (4) interception % component = 2.375 - ((INT/att) × 25). The four values are summed, divided by 6, then multiplied by 100.
The maximum possible Passer Rating is 158.3 (technically 158.33...). Achieving it requires all four components to hit their maximum of 2.375, which requires a completion percentage of at least 77.5%, at least 12.5 yards per attempt, a touchdown rate of at least 11.875%, and zero interceptions.
In the modern NFL, an elite QB typically posts a rating above 100. A rating of 90–100 is considered above average, 80–90 is average, and anything below 70 is considered poor. The NFL average Passer Rating has generally hovered around 88–95 in recent seasons.
The four components are: completion percentage (accuracy), yards per attempt (efficiency), touchdown percentage (big-play production), and interception percentage (ball security). Each is scaled and capped so no single component can dominate the final score.
The theoretical minimum is 0.0. This would occur if a quarterback had 0 completions, 0 yards, 0 touchdowns, and an interception percentage high enough to drive the interception component to 0 or below (which is floored at 0). In practice, extremely low ratings in single-digit territory are very rare.
Passer Rating does not account for sacks, rushing yards, yards after catch by receivers, game situation, or opponent strength. It treats a 1-yard completion the same as a 50-yard completion as long as the per-attempt average holds. Metrics like EPA/play, DVOA, and ESPN's Total QBR (which is a different and more complex metric) attempt to address these gaps.
No. The traditional NFL Passer Rating (computed here) is based solely on completions, attempts, yards, TDs, and INTs using the official formula. ESPN's Total QBR is a proprietary, more advanced metric that factors in all plays a QB is involved in, play context, clutch situations, and opponent quality — and is scored on a 0–100 scale.
