How to use the passer rating calculator
Fill in Attempts, Completions, Passing yards, Touchdown passes and Interceptions for a game or a season. The NFL passer rating appears at once, with a table of its four parts, the formula for each one with your numbers, and the sum at the bottom. Press NCAA passing efficiency to see the college formula for the same line instead. Yards can be negative after a rough day; the other boxes cannot.
The calculator checks the line: completions cannot exceed attempts, touchdowns cannot exceed completions, and interceptions must fit in the incomplete passes. Copy result takes the rating and the working, and Share link sends the line to a friend. As a QB rating calculator it needs no account, and the numbers never leave this device.
Keeping score of the game itself? The football scoreboard runs the clock, downs and score. For standings, use the win percentage calculator; for golfers, the golf handicap calculator.
The formulas, with a worked example
NFL passer rating, as set out by the Pro Football Hall of Fame:
- a = (completions / attempts - 0.3) x 5
- b = (yards / attempts - 3) x 0.25
- c = (touchdowns / attempts) x 20
- d = 2.375 - (interceptions / attempts x 25)
Each part is held between 0 and 2.375, and the rating is (a + b + c + d) / 6 x 100. Because every part tops out at 2.375, a perfect passer rating is 158.3: it takes at least 77.5 percent completions, 12.5 yards per attempt, a touchdown on 11.875 percent of attempts (about 11.9) and no interceptions.
Worked example, the Hall of Fame's own: 336 of 497 for 4,557 yards, 49 touchdowns and 10 interceptions. The parts are a = 1.880, b = 1.542, c = 1.972 and d = 1.872, which add up to 7.266. Divided by 6 and times 100 that is 121.1, the figure the Hall of Fame gives.
NCAA passing efficiency, from the NCAA Football Statisticians’ Manual: (8.4 x yards + 330 x touchdowns + 100 x completions - 200 x interceptions) / attempts, with no limits on the parts. The manual's sample, 98 of 166 for 1,567 yards, 16 touchdowns and 7 interceptions, comes to 161.70 here; the manual shows 161.71 because it rounds each factor to two decimals before adding.

Questions
Why is 158.3 the highest NFL passer rating?
Each of the four parts is capped at 2.375. Four times 2.375 is 9.5, and 9.5 / 6 x 100 = 158.3.
Is passer rating the same as QBR?
No. Passer rating is the public formula on this page, built only from the five numbers in a box score. QBR is a separate metric with its own method, and this calculator does not compute it.
Why can the NCAA number be so much bigger?
The college formula has no caps on its parts and uses different weights, so a short, perfect day can score far above 158.3, and a bad one can go below zero.
Can the rating be below zero?
The NFL rating cannot: each part has a floor of 0, so the lowest rating is 0.0. NCAA passing efficiency can go negative.
