How to Calculate SaaS Session Duration
Step 1: Determine the Total Duration of All Sessions. This is the total time, in minutes or hours, that all users spent within your SaaS application. For example, if 20 users each spent 30 minutes in the app, the total duration is 600 minutes.
Step 2: Identify the Number of Sessions. This is the total count of user sessions during the same time frame you used in Step 1. For example, if the same 20 users each had one session, the number of sessions is 20.
Step 3: Divide the Total Duration of All Sessions by the Number of Sessions. Using the examples, divide 600 minutes (total duration) by 20 sessions. The result, 30 minutes, is the average session duration.
Example 1: Small SaaS Business – A smaller SaaS might have a total session duration of 1200 minutes and 40 sessions; the average session duration is 30 minutes (1200/40).
Example 2: Larger SaaS Platform – A larger platform may have a total session duration of 15000 minutes with 500 sessions, resulting in an average session duration of 30 minutes (15000/500).
Note: Ensure that the time units are consistent (e.g., all in minutes or all in hours). Using a tool like Google Analytics can help you gather these metrics accurately.
