Use this free NFL Passing Touchdown Percentage Calculator to calculate touchdown percentage from passing touchdowns and passing attempts. Enter the two statistics to instantly calculate TD%.
What Is Passing Touchdown Percentage?
Passing Touchdown Percentage (TD%) measures the percentage of a quarterback's passing attempts that result in passing touchdowns.
The calculation divides passing touchdowns by total passing attempts and multiplies the result by 100.
For example, if a quarterback throws 3 passing touchdowns on 35 attempts:
3 ÷ 35 × 100 = 8.57%
The quarterback's passing touchdown percentage is 8.57%.
Passing Touchdown Percentage Formula
The basic formula is:
Passing Touchdown Percentage = (Passing Touchdowns ÷ Passing Attempts) × 100
For example:
(4 ÷ 40) × 100 = 10.00%
A quarterback with 4 passing touchdowns on 40 passing attempts has a passing touchdown percentage of 10.00%.
How to Calculate Passing Touchdown Percentage
You need two statistics to calculate passing touchdown percentage:
- Passing touchdowns — the total number of touchdown passes.
- Passing attempts — the total number of passing attempts.
Follow these steps:
- Enter the number of passing touchdowns.
- Enter the number of passing attempts.
- Divide passing touchdowns by passing attempts.
- Multiply the result by 100.
- Round the result to the desired number of decimal places.
Passing Touchdown Percentage Example
Suppose a quarterback records:
- 5 passing touchdowns
- 50 passing attempts
Apply the formula:
(5 ÷ 50) × 100 = 10.00%
The quarterback's passing touchdown percentage is 10.00%.
Passing Touchdown Percentage Examples
| Passing Touchdowns | Passing Attempts | Passing Touchdown Percentage |
|---|---|---|
| 3 | 35 | 8.57% |
| 4 | 40 | 10.00% |
| 5 | 50 | 10.00% |
| 2 | 30 | 6.67% |
| 6 | 45 | 13.33% |
What Does Passing Touchdown Percentage Mean?
Passing touchdown percentage represents the proportion of passing attempts that resulted in passing touchdowns.
For example, a passing touchdown percentage of 5.00% means that passing touchdowns occurred on 5 out of every 100 passing attempts based on the calculated rate.
It is a rate statistic, not the total number of touchdowns.
Why Is Passing Touchdown Percentage Used?
Passing touchdown percentage is one statistic used to describe passing touchdown production relative to passing attempts.
It can provide context when comparing touchdown totals between players or across different numbers of passing attempts.
However, passing touchdown percentage represents only one aspect of passing statistics and does not describe every part of quarterback performance.
Passing Touchdown Percentage vs. Passing Touchdowns
Passing touchdowns are the total number of touchdown passes, while passing touchdown percentage expresses passing touchdowns relative to passing attempts.
For example:
- Quarterback A: 20 passing touchdowns on 400 attempts = 5.00%
- Quarterback B: 20 passing touchdowns on 500 attempts = 4.00%
Both quarterbacks have 20 passing touchdowns, but their passing touchdown percentages are different because their passing-attempt totals are different.
Passing Touchdown Percentage vs. Completion Percentage
Passing touchdown percentage and completion percentage both use passing attempts as the denominator but measure different outcomes.
Completion percentage:
(Completions ÷ Passing Attempts) × 100
Passing touchdown percentage:
(Passing Touchdowns ÷ Passing Attempts) × 100
Completion percentage measures the percentage of attempts resulting in completions, while passing touchdown percentage measures the percentage resulting in passing touchdowns.
Passing Touchdown Percentage vs. Interception Percentage
Passing touchdown percentage and interception percentage are separate passing statistics.
Passing touchdown percentage:
(Passing Touchdowns ÷ Passing Attempts) × 100
Interception percentage:
(Interceptions ÷ Passing Attempts) × 100
Both use passing attempts as the denominator, but one measures passing touchdowns and the other measures interceptions.
Does Passing Touchdown Percentage Include Rushing Touchdowns?
No. This calculator calculates passing touchdown percentage.
Only passing touchdowns are used as the numerator. Rushing touchdowns by a quarterback are not included.
For example, if a quarterback has 20 passing touchdowns and 5 rushing touchdowns, only the 20 passing touchdowns are used in this calculation.
Does Passing Touchdown Percentage Include Receiving Touchdowns?
No. Receiving touchdowns are not included in passing touchdown percentage.
This calculator is specifically designed for passing touchdowns relative to passing attempts.
Does Passing Touchdown Percentage Include Interceptions?
Interceptions are included in passing attempts, but they are not included in the passing-touchdown total.
Interceptions are measured separately using interception statistics, such as interception percentage.
Single-Game Passing Touchdown Percentage
To calculate passing touchdown percentage for a single game, use the passing touchdowns and passing attempts from that game.
For example:
- 4 passing touchdowns
- 32 passing attempts
Calculation:
(4 ÷ 32) × 100 = 12.50%
The quarterback's passing touchdown percentage for the game is 12.50%.
Season Passing Touchdown Percentage
For a season or multiple-game calculation, use the total passing touchdowns and total passing attempts for the period.
The formula remains:
(Total Passing Touchdowns ÷ Total Passing Attempts) × 100
For example:
- 30 passing touchdowns
- 500 passing attempts
Calculation:
(30 ÷ 500) × 100 = 6.00%
The season passing touchdown percentage is 6.00%.
Do Not Average Game Passing Touchdown Percentages
When calculating a multi-game or season passing touchdown percentage, use the combined passing-touchdown total divided by the combined passing-attempt total.
Do not simply average the passing touchdown percentages from individual games when the games have different numbers of passing attempts.
For example:
- Game 1: 2 TDs on 20 attempts = 10.00%
- Game 2: 1 TD on 40 attempts = 2.50%
The simple average would be:
(10.00% + 2.50%) ÷ 2 = 6.25%
But the combined calculation is:
(2 + 1) ÷ (20 + 40) × 100 = 5.00%
Therefore, the correct combined passing touchdown percentage is 5.00%, not 6.25%.
Passing Touchdown Percentage and Passer Rating
Passing touchdown percentage is one of the statistics used in the traditional NFL passer-rating calculation.
However, passing touchdown percentage by itself is not the passer rating.
Traditional passer rating also uses completion percentage, yards per attempt, and interception percentage.
Use the NFL Passer Rating Calculator to calculate traditional passer rating.
Can Passing Touchdown Percentage Be 0%?
Yes. If a quarterback has zero passing touchdowns and at least one passing attempt, the passing touchdown percentage is 0.00%.
For example:
(0 ÷ 40) × 100 = 0.00%
Can Passing Touchdown Percentage Be 100%?
Mathematically, yes. If every passing attempt results in a passing touchdown, the calculation produces 100%.
For example:
(5 ÷ 5) × 100 = 100.00%
This is a mathematical example rather than an indication of what is typical in NFL game or season statistics.
Can Passing Touchdown Percentage Be Greater Than 100%?
No, assuming valid passing statistics where passing touchdowns do not exceed passing attempts.
Each passing touchdown is associated with a passing attempt, so the basic rate cannot exceed 100% under valid statistical inputs.
Can Passing Attempts Be Zero?
No meaningful passing touchdown percentage can be calculated with zero passing attempts because division by zero is undefined.
This calculator therefore requires at least one passing attempt.
Why Use a Passing Touchdown Percentage Calculator?
This calculator provides a quick way to calculate passing touchdown percentage without manually performing the calculation.
You can use it for:
- Single-game passing statistics
- Season passing statistics
- Quarterback statistics
- NFL statistics research
- Football data analysis
- Fantasy football research
- Checking manual calculations
