Enter the end time and start time into the calculator, and divide the difference by the number of tasks or processes to determine the turnaround time.

Turnaround Time Formula

The following formula is used to calculate the turnaround time:

 TAT = (ET - ST) / N

Variables:

  • TAT is the turnaround time
  • ET is the end time
  • ST is the start time
  • N is the number of tasks or processes

To calculate the turnaround time, subtract the start time from the end time, and then divide the result by the number of tasks or processes.

What is a Turnaround Time?

Turnaround time refers to the amount of time taken to complete a process or fulfill a request. The concept is commonly used in business and technology, particularly in relation to customer service, supply chain management, and information systems. For instance, in customer service, turnaround time might be the time between a customer complaint being filed and the issue being resolved. In supply chain management, it could refer to the time taken from placing an order to delivery. In information systems, turnaround time might be the time taken to process a piece of data or a request. The shorter the turnaround time, the more efficient the process is considered to be. It is a critical measure of efficiency and effectiveness in any operational context.

How to Calculate Turnaround Time?

The following steps outline how to calculate the Turnaround Time:


  1. First, determine the start time of the process.
  2. Next, determine the end time of the process.
  3. Next, subtract the start time from the end time to find the duration of the process.
  4. Finally, calculate the Turnaround Time.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.
