Calculate NCAA passer rating (efficiency) from yards, touchdowns, completions, interceptions, and attempts. The NCAA formula has no cap and differs from the NFL system.
The NCAA passer rating (officially called the NCAA Passing Efficiency rating) uses a completely different formula from the NFL's system. Developed for college football, it weighs yards, touchdowns, completions, and interceptions differently, has no per-component caps, and produces values on a much wider scale — typically ranging from 100 to 200+ for good quarterbacks, with theoretical extreme values going far higher or into negative territory.
Our NCAA Passer Rating Calculator applies the official formula: (8.4×yards + 330×TDs + 100×completions − 200×INTs) / attempts. Enter your passing stats to see where you fall on the college efficiency scale. The calculator also shows an NFL-equivalent passer rating for the same stats, so you can see how the two systems compare.
This tool is essential for college football fans evaluating QB performance, high school players comparing their stats to college benchmarks, and anyone curious about why a college QB's "160 rating" doesn't mean the same thing as an NFL "160 rating."
The NCAA passer rating is the standard efficiency metric for college football. Understanding it helps you evaluate college QBs properly without confusing it with the NFL scale. It heavy-weights touchdowns and harshly penalises interceptions, reflecting the higher-variance nature of college passing. This calculator also shows both NCAA and NFL ratings side-by-side for easy comparison.
NCAA Passer Rating = (8.4 × Yards + 330 × Touchdowns + 100 × Completions − 200 × Interceptions) / Attempts. There is no minimum or maximum cap. For comparison, the NFL formula uses four separately capped components based on COMP%, Y/A, TD%, and INT%.
Result: NCAA Rating: 175.8
Numerator = (8.4 × 3800) + (330 × 35) + (100 × 280) − (200 × 6) = 31,920 + 11,550 + 28,000 − 1,200 = 70,270. Rating = 70,270 / 400 = 175.7. This would be an excellent season in FBS competition. For reference, the all-time NCAA single-season record is about 191.8 (Joe Burrow, 2019 LSU).
The two passer rating systems were designed decades apart with different philosophies. The NFL's bounded system prevents any single stat from dominating and normalises to a 0–158.3 scale. The NCAA's unbounded linear formula lets dominant performances produce extremely high values, which can be more exciting but less nuanced. Neither is objectively better; they simply measure different aspects of efficiency differently.
In the NCAA formula, one touchdown adds 330 points to the numerator while one interception subtracts 200. This 330:200 ratio means a QB who throws one TD and one INT nets +130, still modestly positive. One completion is worth +100, and one yard is worth +8.4. To match one extra touchdown's value through yards alone, a QB would need about 39.3 extra yards. These weights heavily favour scoring efficiency.
The modern passing era (2015–present) has seen unprecedented efficiency numbers. Spread offences, RPO schemes, and rule changes protecting passers have pushed completion percentages above 70% for top QBs. Joe Burrow's 2019 season (60 TDs, 6 INTs, 5,671 yards) set the standard that may stand for years.
The systems were developed independently for different purposes. The NFL formula (1973) creates a bounded 0–158.3 scale using four capped components. The NCAA formula is simpler and unbounded, directly weighting yards, TDs, completions, and INTs. The different scales reflect different priorities: the NCAA version is effectively a linear point system rather than a normalised efficiency index.
In FBS, the national average is roughly 120–130. A rating of 140+ is above average, 150+ is very good, 160+ is excellent, and 170+ is elite. The all-time single-season record is Joe Burrow's 202.0 during LSU's 2019 championship run (though some sources adjust this to 191-193 depending on totals used).
Theoretically yes. If a quarterback throws many interceptions relative to completions, yards, and touchdowns, the −200×INTs term can overwhelm the positive terms. In practice, this would require historically bad performance: lots of interceptions, very few completions, and minimal yards. It almost never happens in real games.
You can't directly convert between them because the formulas are fundamentally different. However, as a rough guideline: an NCAA rating of 150 corresponds to roughly 90–95 NFL rating for similar underlying stats. The best approach is to calculate both ratings from the same stat line, which this calculator does for you.
Career NCAA passing efficiency leaders include Tua Tagovailoa (Alabama, 199.4 — though he only started two seasons before going pro), Mac Jones (Alabama), and Joe Burrow (LSU). These records can shift depending on how transfers and minimum-attempt thresholds are applied. Historically, the 2018–2021 era produced many of the highest career marks.
The formula can be applied to any passing stats, but high school context is very different from college. There is no official "high school passer rating," so using the NCAA formula for comparison purposes is reasonable, keeping in mind that competition levels vary enormously. A 180 rating in top-level high school ball may not translate to the same college.
