Enter attempts, completions, yards, touchdowns and interceptions; the calculator returns the official NFL passer rating, its four parts and where any part hits the 2.375 cap.

NFL passer rating (often called QB rating) turns five numbers, attempts, completions, yards, touchdowns and interceptions, into four per-attempt parts. Each part is held between 0 and 2.375; the four are added, divided by 6 and multiplied by 100. The scale runs from 0.0 to 158.3, a perfect rating. Enter a passing line below to see all four parts and where any of them hits its cap.

The calculator opens on Lamar Jackson's 2024 regular season, the worked example below. It works for a single game, a season or a career: the formula only uses totals.
With ATT attempts, CMP completions, YDS yards, TD touchdown passes and INT interceptions:
Any part above 2.375 is set to 2.375, and any part below zero is set to zero. Then:
passer rating = (a + b + c + d) / 6 × 100
Because each part stops at 2.375, the most a passer can score is 4 × 2.375 / 6 × 100 = 158.3. The caps are reached at these rates:
| Part | Reaches 2.375 (cap) at | Falls to 0 at |
|---|---|---|
| a — completions | 77.5% completed | 30.0% completed |
| b — yards per attempt | 12.5 yards per attempt | 3.0 yards per attempt |
| c — touchdowns | a touchdown on 11.875% of attempts | no touchdowns |
| d — interceptions | no interceptions | an interception on 9.5% of attempts |
A single incomplete pass scores 39.6: only the interception part is above zero. With zero attempts there is no rating at all, because every part divides by attempts.
Jackson led the NFL in passer rating in 2024 at 119.6. His regular-season line was 316 completions in 474 attempts for 4,172 yards, 41 touchdowns and 4 interceptions:
No part hit a cap: his completion rate (66.7%) was well short of 77.5%, and his yards per attempt (8.80) short of 12.5. What carried the number was the pairing of a touchdown on 8.6% of his throws with an interception on 0.8%.
One more throw on top of that season shows how unevenly the formula weighs plays:
| The 475th throw is… | New rating | Change |
|---|---|---|
| a 25-yard touchdown pass | 120.5 | +0.85 |
| a 10-yard completion | 119.6 | +0.02 |
| an incompletion | 119.4 | −0.25 |
| an interception | 118.5 | −1.12 |
For a passer at this level, one interception costs more than a touchdown adds, and an ordinary 10-yard completion barely moves the rating at all.
In week 7 of 2025, Hurts completed 19 of 23 passes for 326 yards, 3 touchdowns and no interceptions. Before the caps, his parts were a = 2.630, b = 2.793, c = 2.609 and d = 2.375. All four sit at or above 2.375, so all four count as 2.375 and the rating is (4 × 2.375) / 6 × 100 = 158.3. Anything more (another touchdown, more yards) adds nothing once every part is capped.
