Engagement (DAU / WAU / MAU)

Engagement Metrics track how often users interact with your product over time. DAU, WAU, and MAU are standard metrics to measure activity, stickiness, and product adoption in startups.

🧩 What Are DAU, WAU, MAU?

  • DAU (Daily Active Users) — number of unique users who interact with your product in a day.
  • WAU (Weekly Active Users) — number of unique users who interact with your product in a week.
  • MAU (Monthly Active Users) — number of unique users who interact with your product in a month.

These metrics help you understand how frequently users engage and whether your product is “sticky.”

🧠 Why Engagement Metrics Matter (Especially for Startups)

Engagement Metrics answer critical questions for founders:

  • Are users coming back regularly?
  • Which periods show higher or lower activity?
  • Is the product sticky enough to retain users?
  • How do changes in features, onboarding, or campaigns affect usage?

High engagement indicates strong product-market fit, which leads to higher retention and LTV.

📘 How to Calculate DAU / WAU / MAU

  • DAU: Count unique users who interacted with your product in a single day.
  • WAU: Count unique users who interacted in the last 7 days.
  • MAU: Count unique users who interacted in the last 30 days.

You can also calculate the DAU/MAU ratio to measure stickiness:

DAU/MAU (%) = (DAU ÷ MAU) × 100

A higher DAU/MAU ratio means users return frequently and your product is more engaging.

💡 Common Mistakes Founders Make

  • Counting total logins instead of unique users
  • Mixing active users with inactive or trial accounts
  • Not defining activity clearly (what counts as an interaction)
  • Ignoring seasonality or weekly/monthly patterns

⭐ Practical Examples

Example 1: Mobile App
DAU = 1,000
MAU = 4,000
DAU/MAU = 25% (users open the app ~1/4 of days in a month)

Example 2: SaaS Startup
WAU = 600
MAU = 1,200
WAU/MAU = 50% (half of monthly users are active weekly)

Example 3: E-commerce
DAU = 500
MAU = 2,000
DAU/MAU = 25% (frequent buyers or visitors)

🎯 Startup Rule (Remember This)

Tracking engagement consistently reveals product health and helps optimize onboarding, features, and retention strategies.
