Enter the request time (ms) and the process time (ms) into the Calculator. The calculator will evaluate the Access Time. 

Access Time Formula

AT = RT + PT


  • AT is the Access Time (ms)
  • RT is the request time (ms)
  • PT is the process time (ms)

To calculate Access Time, simply sum the request time and the total processing time.

How to Calculate Access Time?

The following steps outline how to calculate the Access Time.

  1. First, determine the request time (ms). 
  2. Next, determine the process time (ms). 
  3. Next, gather the formula from above = AT = RT + PT.
  4. Finally, calculate the Access Time.
  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.

request time (ms) = 0.34

process time (ms) = 0.12
