What is the NFL Passer Rating?
The NFL passer rating is the league’s official metric for evaluating quarterback passing efficiency. Established in 1973 by a special committee headed by Don Smith, it was created because analyzing individual stats (like completion percentage or yards) wasn’t painting a complete picture of player value.
The metric operates on a scale from 0.0 to 158.3. It is commonly referred to interchangeably as “Quarterback Rating,” though it should not be confused with ESPN’s modern QBR metric (which ranges from 0 to 100).
The NFL purposefully designed the formula to weigh four distinct categories equally: accuracy, explosion (yards), scoring (touchdowns), and ball security (avoiding interceptions).

The beauty of the NFL formula lies in its 4 independent components. Every component is rigorously mathematically clamped between 0 and 2.375. This ensures no single stat (like a massive 80-yard screen pass) breaks the formula.
Completion %
(COMP/ATT − 0.3) × 5Penalizes completion percentages below 30% and caps the benefit at 77.5%.
Yards per Attempt
(YDS/ATT − 3) × 0.25Rewards explosive offenses. Capped at 12.5 yards per attempt.
Touchdown %
(TD/ATT) × 20Heavily weights scoring drives. Maxes out when 11.875% of throws are TDs.
Interception %
2.375 − (INT/ATT × 25)Severely punishes turnovers. Reaches zero when 9.5% of throws are picked off.

The Anatomy of a Perfect 158.3 NFL Rating
A perfect NFL passer rating is exactly 158.3. It is the mathematical ceiling.
To score exactly 158.3, a quarterback must simultaneously hit the maximum threshold (2.375) across all four separate mathematical categories in the formula.

NFL Rating Tiers & Benchmarks
What is a good NFL rating today? Because the game has prioritized passing, the standard for “Average” is much higher than it was in the 1970s.
Elite
110+
All-Pro caliber, MVP-level efficiency.
Good
90–110
Reliable starter, Pro Bowl trajectory.
Average
75–90
League average, functional but flawed.
Poor
Below 75
Struggling heavily, at risk of benching.

NFL Rating vs. Total QBR
They sound identical, but serve different purposes. ESPN introduced Total QBR in 2011 to solve the “flaws” in traditional passer rating.
Traditional NFL Rating
- ✓ Open-source mathematical formula.
- ✓ Comparable across the entire Super Bowl era.
- ✗ Doesn’t account for QB rushing or scrambles.
- ✗ Doesn’t penalize for taking massive sacks.
ESPN Total QBR
- ✓ Scales sensibly from 0 to 100.
- ✓ Incorporates rushing, clutch-factor, and EPA.
- ✗ Proprietary, hidden formula owned by ESPN.
- ✗ Extremely complex to calculate independently.

Frequent NFL Rating Questions
Frequently Asked Questions
Everything you need to know about passer rating and how to calculate it.
What is the highest possible NFL rating?
158.3. This occurs when a quarterback perfectly maxes out the internal metrics: 77.5%+ completion rate, 12.5+ YPA, 11.875%+ TD rate, and 0 INTs.
What is the average NFL passer rating?
In the modern passing era (post-2015), the league average rating typically hovers between 89.0 and 93.0. Back in the 1970s, it was closer to 65.0.
Why is 158.3 the cap?
Because each of the four components is mathematically capped at 2.375. If you average 2.375 out and multiply by the 100/6 scaling factor, you get precisely 158.3333...
Do sacks count against NFL rating?
No. Sacks and lost fumble yardage are not factored into the official NFL passer rating formula. They only affect metrics like Adjusted Net Yards per Attempt (ANY/A) and QBR.
Does rushing affect my rating?
No. The formula strictly measures passing performance. A QB could rush for 200 yards, but if they threw poorly, their passer rating would remain terrible.
