NFL Passer Rating Calculator
Enter completions, attempts, passing yards, touchdowns and interceptions to get the official NFL passer rating instantly — the same 0-to-158.3 formula the league has used since 1973. Switch to the NCAA tab for the college passing efficiency formula.
The NFL Passer Rating Calculator computes the league's official quarterback rating from five box-score numbers: completions, attempts, yards, touchdowns and interceptions. The result updates as you type, shows the four component scores so you can see exactly what helped or hurt the rating, and flags a perfect 158.3. The NCAA toggle switches to the college passing efficiency formula, which uses the same five inputs but a completely different scale. Everything runs in your browser — no sign-up, nothing uploaded.
How NFL Passer Rating Is Calculated
The NFL formula, adopted in 1973, scores four categories — completion percentage, yards per attempt, touchdown percentage and interception percentage — each on a scale from 0 to 2.375:
a = (Comp/Att − 0.3) × 5
b = (Yards/Att − 3) × 0.25
c = (TD/Att) × 20
d = 2.375 − (INT/Att × 25)
Each component is capped between 0 and 2.375, then: Rating = ((a + b + c + d) ÷ 6) × 100. That cap is why the maximum possible rating is exactly 158.3 — achieved with at least 77.5% completions, 12.5+ yards per attempt, a touchdown on at least 11.875% of attempts, and zero interceptions.
The NCAA formula is different
College football uses passing efficiency instead: (8.4 × Yards + 330 × TD + 100 × Comp − 200 × INT) ÷ Attempts. It has no caps, so ratings above 200 are common for elite college seasons and the theoretical range is roughly −731 to 1,261. Never compare an NFL rating to an NCAA rating directly — a 158.3 in the NFL and a 180 in college are both excellent, but they live on unrelated scales.
What Counts as a Good Passer Rating?
| NFL rating | Verdict |
|---|---|
| 158.3 | Perfect game |
| 110+ | Elite performance |
| 95–110 | Very good |
| 85–95 | Around league average |
| 70–85 | Below average |
| Under 70 | Poor day |
League-wide averages have climbed for decades as passing offenses evolved — a 90 rating was elite in the 1990s and is roughly average in the modern NFL. That's worth remembering when comparing eras.
Passer rating vs QBR
Passer rating is not ESPN's Total QBR. Passer rating is a pure box-score formula anyone can compute (that's what this calculator does); QBR is a proprietary 0–100 model that folds in play-by-play context, rushing, sacks and win probability. The two often disagree — a QB can post a high passer rating from safe short throws while QBR grades the same game as mediocre.
