Percent Delay Formula

The following two example problems outline the steps and information needed to calculate the Percent Delay.

PD = (Tac - Ta l) / Tal* 100

Variables:

• PD is the Percent Delay (%)
• Tac is the actual time (min, hrs) 
• Tal is the allocated time (min, hrs) 

To calculate the percent delay, subtract the allocated time from the actual time, then divide by the allocated time. Finally multiply by 100 to get the result as a percentage.

How to Calculate Percent Delay?

The following steps outline how to calculate the Percent Delay.

1. First, determine the actual time (min, hrs). 
2. Next, determine the allocated time (min, hrs). 
3. Next, gather the formula from above = PD = (Tac – Ta l) / Tal* 100.
4. Finally, calculate the Percent Delay.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

actual time (min, hrs) = 6

allocated time (min, hrs) = 3

PD = (Tac – Ta l) / Tal* 100 = ?
