DAU vs WAU vs MAU

Three time windows for counting active users. The window you choose changes the story. This comparison covers all three plus the stickiness ratios between them.

Last updated: 2026-04-01

Overview

DAU
24-Hour Window

Daily Active Users. Unique users who perform a qualifying action within a single day, usually a calendar day in a fixed timezone. The right metric for products people are expected to use daily.

Best for daily-use products: messaging, social feeds, productivity tools, news. Tracks habit formation and reacts quickly to changes.

WAU / MAU
7-Day & 30-Day

Weekly Active Users count unique users in a rolling 7-day window. Monthly Active Users count unique users in a rolling 30-day window. Both smooth out daily noise and forgive less-frequent usage.

WAU best for weekly-cadence products (banking, fitness, project tools). MAU best for episodic products (tax software, travel) and investor reporting.

Formula comparison

DAU

DAU = unique users active in a 24-hour calendar day

A user who opens your app five times in a day counts as 1 DAU, not 5. Deduplication by user ID is essential.

WAU / MAU

WAU = unique users in rolling 7 days. MAU = unique users in rolling 30 days.

Rolling windows avoid calendar artifacts. February has 28 days. March has 31. Rolling 30-day MAU keeps the comparison honest.

When to use each

Choose DAU when
  • The product is meant to be used every day
  • You're tracking habit formation
  • A daily metric is the user-facing promise (streaks, daily journals, news)
  • Engineering needs to size daily peak load
  • You want the most sensitive signal of product changes
Choose WAU / MAU when
  • The product has a weekly or monthly cadence
  • You want to smooth weekend dips for B2B
  • Monthly check-ins are the actual usage pattern
  • You're reporting to investors who use MAU as the comparable
  • Daily usage is unrealistic but monthly is too forgiving (use WAU)

Pros and cons

DAU

Pros

  • Most sensitive to changes. You see problems quickly
  • Natural for habit-forming products
  • Useful for capacity planning at peak

Cons

  • Looks bad for products that aren't daily-use, even when they're healthy
  • Volatile day-over-day. Holidays and weekends distort it
  • Easy to game with low-bar definitions of "active"

WAU / MAU

Pros

  • Smooths daily noise. Less affected by holidays and weekends
  • Easy to compare to industry benchmarks (especially MAU)
  • Forgiving of irregular usage patterns

Cons

  • Slow to react to product changes (especially MAU)
  • Hides churn for up to 30 days
  • Easiest to game with low-bar "active" definitions

Frequently asked questions

What's a good DAU/MAU ratio?

Across all industries, Mixpanel's 2024 benchmark report puts the cross-industry average at 37%. By industry: 50% or higher for social and messaging, 40 to 60% for productivity, 13% for SaaS, 10% for e-commerce, around 10% for fintech. Sequoia's 2014 rule of thumb of 10 to 20% is now dated for consumer apps but still reasonable for SaaS.

Should I report DAU, WAU, or MAU to my board?

The one that matches the product's natural usage cadence. A daily-use product reporting MAU is hiding decay. A monthly-use product reporting DAU looks unhealthy compared to peers. Pick the window that lets the metric move when usage moves.

How do I count an "active" user?

Define one qualifying action and stick with it. For a chat product, that might be sending a message. For analytics tooling, opening a dashboard. Avoid "logged in" as the bar. Logged-in but inactive sessions inflate the number without reflecting real engagement.

Is the time window calendar or rolling?

DAU is usually a calendar day in UTC. WAU and MAU are rolling 7-day and 30-day windows. Calendar months would make February shorter than March and create artificial fluctuations. Rolling windows give you smoother trend lines.

Why does DAU/MAU vary so much by industry?

Because the natural usage cadence varies. Slack and WhatsApp users show up daily. Tax software users show up annually. The ratio reflects how often real users have a reason to come back, not how good the product is.
