In a SaaS context, Weekly Active Accounts measures the number of unique accounts, either free or paid, with at least one user who has interacted with an application or platform in a week. Weekly Active Accounts is one measure of the growth of an application’s usage over time and can be used in other contexts as well, for example, forums. In this context, Weekly Active Accounts measures accounts with forum post or other interactions occurring weekly.
In SaaS, the Weekly Active Accounts metric should not be used in isolation. It is important to measure Weekly Active Users in conjunction with Weekly Active Accounts. This is because there is a big difference in value and stickiness between an account with 50 users, of whom only 2 are active, and an account with 50 users, of whom 48 are active. The account with 48 active users is more likely to renew and expand their subscription, if we assume that activity is creating value for users.
