Free tool DAU/MAU ratio calculator

DAU/MAU is the share of your monthly users who show up on a typical day. Enter daily and monthly active users, and optionally weekly, to see how sticky the product is and how many days a month the average user comes back.

Work out stickiness

Use the average daily active users over the same 30 days as your MAU. WAU is optional.

Average distinct active users per day over the month.

Distinct active users over the same 30 days.

Average distinct active users per 7 days. Adds DAU/WAU.

What stickiness tells you, and what it does not

DAU/MAU measures how often people come back, not how many people you have. A small product can be very sticky; a huge one can be visited once a month.

DAU/MAU

The sample gives 12,400 ÷ 52,000 = 23.8%: on a typical day, about one in four of this month’s users is active.

Active days per month

23.8% × 30 ≈ 7.2 days. Easier to explain than a ratio: the average monthly user is active about seven days a month.

DAU/WAU

The same idea over a week. 43.5% × 7 ≈ 3 days a week. Useful for products used on workdays, where a monthly window blurs the pattern.

Natural frequency

A team chat tool should be used daily; a travel booking site maybe a few times a year. Judge the ratio against how often your product is meant to be used.

The ratio depends entirely on what counts as "active". Opening the app, viewing a page and completing a core action give very different numbers.

How to use it

Three things to settle first

The division is trivial. The inputs decide whether the ratio means anything.

  1. 1

    Define "active"

    Pick one qualifying action — a session, a message sent, an order — and use it for DAU, WAU and MAU alike.

  2. 2

    Use the same window

    DAU should be the daily average over the same 30 days that MAU covers, not a single good day.

  3. 3

    Count people, not devices

    A user on phone and laptop should count once. Device-based counts inflate MAU more than DAU and pull the ratio down.

Formula

Stickiness = DAU ÷ MAU

DAU and MAU are distinct people who did the qualifying action in a day and in 30 days. Their ratio is the share of monthly users who show up on an average day.

  • DAU must not exceed MAU; WAU sits between them
  • Active days per month = DAU/MAU × 30
  • Days per week = DAU/WAU × 7

DAU/MAU

stickiness = DAU ÷ MAU

12,400 ÷ 52,000 = 23.8%

DAU/WAU

DAU ÷ WAU

12,400 ÷ 28,500 = 43.5%

Active days

active days = DAU/MAU × 30

23.8% × 30 ≈ 7.2 days a month

Worked example

Three products, three rhythms

Three products with similar monthly audiences. Their stickiness differs because people need them at different frequencies, not because one is failing.

A 5% ratio is normal for a store people visit when they need something; it would be alarming for a team chat tool. Compare each product with its own history. Sample figures.

Common mistakes

Where DAU/MAU misleads

Small changes in definition move this ratio a lot.

Using one day as DAU

A launch-day DAU over a normal month’s MAU overstates stickiness. Use the daily average for the month.

Counting devices

Without identity resolution one person on two devices inflates the counts, MAU most of all.

A loose definition of active

Counting background app opens or push-notification taps makes the ratio look healthy while real use falls.

Reading it during fast growth

A wave of new sign-ups raises MAU before those users form habits, so the ratio dips even if nothing is wrong.

DAU/MAU questions

What is the DAU/MAU ratio?

Daily active users divided by monthly active users. It is called stickiness: the share of the people who use your product in a month who use it on a typical day.

How do I calculate DAU/MAU?

Take the average daily active users over a 30-day period and divide by the distinct active users in the same period. 12,400 ÷ 52,000 = 23.8%.

What is a good DAU/MAU ratio?

It depends on how often your product is meant to be used. A daily tool and a monthly-purchase store should not share a target. Track your own ratio over time and by segment, with the same definition of "active".

What does a DAU/MAU of 50% mean?

The average monthly user is active on about half the days of the month, roughly 15 days out of 30.

What is the difference between DAU/MAU and retention?

Retention follows one cohort over time: how many of the people who joined came back. DAU/MAU is a snapshot across all users in a month. Use the retention calculator for cohorts.

Why should I add WAU?

DAU/WAU shows the weekly rhythm. For workday products, a 70% DAU/WAU (about five days a week) can sit beside a modest DAU/MAU and still be healthy.
