DAU / MAU calculator
DAU/MAU is daily active users divided by monthly active users. It is a rough measure of how often the people who use your app at all come back within a month. A ratio of 0.2 means the average monthly user shows up on about six days out of thirty.

Translate the ratio into frequency
Multiplying DAU/MAU by 30 gives a rough number of active days per monthly user. It is easier to discuss, but it remains an average: some people may use the app daily while many use it once.
DAU: 2,000 MAU: 10,000 DAU/MAU: 0.20 · 20% Approximate frequency: 6 active days in 30
How it is calculated
DAU/MAU = DAU ÷ MAU · as a percentage, × 100
When to use it
Use it to watch one app change over time. A ratio that falls while both numbers grow means you are acquiring people who do not stick, which neither figure shows on its own.
What to watch out for
- There is no universal "good" ratio — it depends entirely on what kind of app you built, and a messaging app and a tax app should not have the same one
- DAU is one day, so pick a representative one; a launch day or a public holiday will mislead
- MAU cannot be smaller than DAU, because everyone active today is active this month
- Across several Analytics properties, the same person can be counted twice, which inflates both numbers unevenly
Frequently asked questions
What does a DAU/MAU ratio of 0.2 mean?
It means daily active users equal 20% of monthly active users, roughly six active days per monthly user in a 30-day month.
What is a good DAU/MAU ratio?
There is no universal benchmark. Compare the same app over time because expected frequency differs greatly by product category.
Why can DAU not exceed MAU?
Every user active today is also part of the monthly active population when both metrics use the same definition and reporting date.
