NFL QB Rating Calculator
Calculates the NFL quarterback rating.
Formula: ((at=((100 * comp / att)-30)*.05)+(bt=(yards/att-3)*.25)+(ct=(td/att)*20)+(dt=2.375-(25*intr/att)))*0 + (max(min(at, 2.375), 0) + max(min(bt, 2.375), 0) + max(min(ct, 2.375), 0) + max(min(dt, 2.375), 0))*100/6
Comp: The number of completed passes.
Att: The number of attempted passes.
Yards: The total passing yards.
TD: The number of touch downs.
Intr: The number of interceptions.
Example 1
Calculate the QB rating for Steve Young's record-setting season in 1994 when he completed 324 of 461 passes for 3,969 yards, 35 touchdowns, and 10 interceptions.
| Value | Keystrokes | Display | Description |
|---|---|---|---|
| 324 | Comp | 324.0000 | Stores the Comp value. |
| 461 | Att | 461.0000 | Stores the Att value. |
| 3969 | Yards | 3,969.0000 | Stores the Yards value. |
| 35 | TD | 35.0000 | Stores the TD value. |
| 10 | Intr | 10.0000 | Stores the Intr value. |
| Rating | 112.7937 | Calculates Rating. |
Example 2
Calculate the Yards required for a Rating of 115.
These keystrokes assume the values from example 1.
| Value | Keystrokes | Display | Description |
|---|---|---|---|
| 115 | Rating | 115.0000 | Stores the Rating value. |
| Yards | 4,213.1 | Calculates the Yards value. |
Note the technique used for this complex formula. The four temporary values, at, bt, ct and dt are calculated first and then used in the max/min formula as given in the reference. To see the value of a variable just enter the name of the variable in formula mode. For example, "=f at =" will display the at value of 2.0141.
