Sports calculators are important for any athlete or physically active person. A sports calculator is developed to use match statistics and present players’ facts and current statuses. One of the important calculators is our Passer Rating Calculator.

It has been a while since sports became more than just a game and fun for players and the audience. With scoring, passing, and fast running, many scientific kinds of research and proven facts can help improve professional performance. With the improvements in science and technology, athletes can use new methods to improve their results. Sport calculator is an efficient tool that gives directions on what players need to improve.

Sports statistics can be visible to the audience. But they are just one small part of how science and technology can affect sports. Many important calculations are truly helpful for the better performance of a player. Sports calculators use advanced formulas for the actual rates and efficiencies. Here, we will present the passer rating calculator used in American football, NFL.

Also, other useful calculators help users calculate their sports efficiencies and predictions using data or average values. Race Predictor and Average Rating Calculator are one of many.

## What is the passer rating?

Passer rating or passing efficiency is a measure of the performance of passers in American football. It shows how efficient passers are, mostly quarterbacks in the NFL, CFL, and college football in NCAA. The success of a performance depends on many things: number of pass attempts and completions or successful passes, number of touchdowns, gained yards, interceptions.

Before, the first attempt to calculate the passer rating did not correctly include many of these criteria. So, the ranking system was never accurate. Later in 1973, after a new attempt, they developed a new passer rating system that included these categories from the statistics to demonstrate the passer’s accurate performance. An accurate passer rating helps the player improve performance by considering his strengths and weaknesses from statistics. One of the most successful quarterbacks is Aaron Rodgers, a Packer quarterback with a recent NFL passer rating record of 141.1.

## How is the passer rating calculated?

The passer rating system had many changes since the leagues’ board was trying to find the right approach and formula, to not leave any important data unconsidered. They established the current system in 1973, which includes these important factors:

• passing attempts
• completions
• number of passing yards
• completed touchdowns
• interceptions

## Passer rating formula

The passer rating formula in NFL and CFL is calculated in one way, whereas NCAA college football uses different calculations. However, for both formulas, we use the same data.

### NFL and CFL

The passer rating system has a sliding scale design, where the lowest ranking is zero, while the highest rating can be 158.3. One can calculate the passer rating formula by arranging data into four statistical categories. They become four important variables used as a base for the final formula. The number of passing attempts is used in all four categories. In any given category, the quarterback can explicitly have a maximum rating of 2.375.
For these calculations, we will use abbreviations of given terms.

The first category combines the number of passes completions (COMP) and the number of passing attempts (ATT). Next, the quotient is used for further calculations. It then gives us a calculation for the first variable of the final Passer rating formula.

A=\left ( \frac{COMP}{ATT} - 0.3\right ) \times 5

The result is the completion percentage of a player.

Further, the second category combines the number of passing attempts with passing yards (YDS). Here, we calculate the successful yards per attempt with the given quotient.

We find the second variable with this:

B=\left ( \frac{YDS}{ATT} -3\right ) \times 0.25

After that, the third category gives us the third variable of the final formula. Again, it is calculated with the statistics of made touchdowns (TD) and passing attempts.

C =\left ( \frac{TD}{ATT} \right )\times 20

Subsequently, to calculate the fourth category, we use the data of completed passes interceptions (INT) and passing attempts. The result gives us the fourth variable.

D=2.375-\left ( \frac{INT}{ATT} \times 25\right )

If the value of any category is less than zero, it is set to zero. Also, if the value is greater than the maximum allowed number 2.375, the value must be set to 2.375.

Finally, the results of all four categories, the addition of them is divided by 6, and then it is all multiplied by 100 to get the right number. Therefore, the final passer rating formula (here PR) for NFL and CFL is:

PR = \left ( \frac{A+B+C+D}{6} \right ) \times100

### NCAA passer rating formula

The National Collegiate Athletic Association developed another formula for their college football passers. Although they use the same categories, they have different multiplications and do not set limits to the values of the categories.

PR_{NCAA}=\frac{\left ( 8.4 \times YDS \right )+\left ( 330 \times TDP \right )+\left (  100 \times COMP\right )-\left ( 200 \times INT \right )}{ATT}

## Learn to count like this QB passer rating calculator

In the following lines, we will show you one example of how the NFL/CFL passer rating formula works.

Let’s say that a quarterback had 30 pass attempts and 15 pass completions in one match. He gained 278 passing yards, achieved four touchdowns, and had one interception. Then, following the procedure from above, we first have to find the results of all four categories to get variables. Those variables we will use in a final passer rating formula.

For A = ((15\div 30) – 0.3) \cdot 5 , from the calculation, we get that the first variable is 1 (completion percentage).
For B = ((278\div 30) - 3) \cdot 0.25 , from this, we get the second variable with the value of 1.5666.
From the third category, we have C = (4\div 30) \cdot 20 . Then the value of the variable is 2.6666. But, since the value exceeds the maximum possible value, we take 2.375 as a result. Hence, C = 2.735 .
Then, the fourth category calculates subscribing some value from the maximum of 2.375.
In other words, D = 2.375 – (1\div 30) \cdot 25. That gives us the D value of 1.5416.
When we put these variables into the passer rating formula, we get that this player’s

PR= \left [ \frac {(1+1.5666+2.375+1.5416)}{6}  \right] \cdot 100 = 108.06

The final result is 108.06.

But luckily, you don’t need to calculate this on your own. If you want to save some time, a passer rating calculator can undeniably help you. Our passer rating calculator is a simple tool that does all the work for you.

## FAQ

What is a passer rating and where is it used?

Passer rating is a measure that shows how efficient was a quarterback player during the game or season. It measures his performance. This system is used in American football, with two established formulas for NFL and CFL, and NCAA or college league football.

How can we calculate passer rating?

To calculate this rating efficiently, we need statistics from four major categories: passing attempts, completions, if the player made any touchdown, gained passing yards, and the number of interceptions. Thus, the final formula for the passing rating in the NFL and CFL is PR= [\frac{(A+B+C+D)}{6}] \cdot 100. Passer rating calculator uses these formulas to calculate the accurate rating in American football.
