What is Stickiness Ratio?

Why It Matters

Stickiness ratio tells a team whether growth in monthly users is actually translating into habitual, everyday use or just occasional drop-ins. A product can grow MAU steadily while stickiness quietly declines, which signals that new users are trying the product once or twice and drifting away rather than building a routine around it. Because the healthy range differs enormously by product category, stickiness ratio only means something when read against what the product is supposed to be used for, not against a universal benchmark. Teams use it to judge whether feature launches or onboarding changes actually deepen engagement rather than just adding new signups. Ignoring it can hide a churn problem forming well before cancellation numbers show it.

Example

A product averages 12,000 daily active users and has 60,000 monthly active users. Stickiness ratio is 12,000 divided by 60,000, times 100, which equals 20%, meaning the average monthly user engages with the product on about 6 days out of every 30. A social or messaging app might target a stickiness ratio above 50%, since daily use is core to the product, while a tax filing or annual planning tool would consider a much lower ratio perfectly healthy given how the product is naturally used.

Frequently Asked Questions

• What counts as an 'active' user in this calculation?

  It depends on how the product defines activity, usually opening the app or performing at least one meaningful action, and DAU and MAU should use the exact same activity definition or the ratio becomes meaningless.

• How is stickiness ratio different from retention rate?

  Retention rate tracks whether the same individual users come back over time, while stickiness ratio is a snapshot ratio of two aggregate counts, DAU and MAU, that doesn't track specific users across periods.

• What is a good stickiness ratio?

  It varies widely by category. Daily-use products like social or messaging apps often aim above 50%, while products used weekly or monthly, like project planning or tax tools, are healthy well below that.

• How often should stickiness ratio be tracked?

  Most teams review it weekly or monthly alongside DAU and MAU trends, since a single day's snapshot is too noisy to act on.

• What typically causes stickiness ratio to fall?

  A falling ratio usually means MAU is growing faster than DAU, often from marketing pulling in new or casual users faster than the product is turning them into daily habits.
