Daily Active Users (DAU) is a key engagement metric that measures the number of unique users who interact with your product, app, or platform on a given day.
It helps SaaS and digital businesses assess product stickiness, user engagement, and adoption trends.
You can calculate DAU by counting the unique users who perform at least one qualifying action in your product on a specific day.
Define “Active”. Decide what counts as an active user for your product (e.g., login, purchase, message sent, file uploaded).
Track User Activity. Collect event data from product analytics, CRM, or backend systems.
Remove Duplicates. Only count unique users (e.g., a user logging in multiple times in one day counts as 1 DAU).
Aggregate Daily. Report the number of unique active users per day.
DAU = Count of Unique Users Active in a Day
There is no universal benchmark since DAU depends heavily on product type and industry. However, DAU is often evaluated in terms of DAU/MAU Ratio (Stickiness):
DAU is a leading indicator of user engagement and retention. If DAU grows steadily, it signals product adoption and customer value.
Not necessarily. DAU includes all unique active users, whether free, trial, or paid, depending on what you want to analyze.
Yes, if not paired with retention, revenue, or depth of activity metrics. High DAU with low revenue may mean users are engaged but not monetized.
