Monthly Active Users (MAU) Calculator
Compute MAU, DAU/MAU stickiness, activation rate, and month-over-month growth for your SaaS or consumer product.
Why MAU Is Both Useful and Misleading
Monthly Active Users (MAU) is the workhorse metric of consumer and SaaS analytics — but it hides important variation. A product with 100K MAU where each user logs in once per month is fundamentally different from a product with 100K MAU where each logs in daily. Always pair MAU with DAU/MAU stickiness ratio and average sessions per user.
The standard MAU definition: a unique user who took at least one action in your product within a 30-day window. Define 'action' clearly — opening the app vs taking a meaningful action (sending a message, creating a record, viewing 3+ screens). Loose definitions inflate MAU and tank engagement metrics.

DAU/MAU Stickiness Benchmarks
| Product Category | Healthy Stickiness |
|---|---|
| Daily-use communication (Slack, WhatsApp) | 50-70% |
| Social networks | 40-65% |
| Consumer productivity (Notion, Trello) | 20-35% |
| B2B SaaS (typical) | 10-20% |
| Vertical SaaS (less frequent use) | 5-15% |
| Periodic-use tools (tax, accounting) | 3-8% |
Compare to similar products — a 10% stickiness is great for a tax calculator and terrible for a chat app.
Activation Rate — The Leading Indicator
Activation rate = % of new signups who reach the 'aha' moment (took a core action in a defined timeframe). Examples: WhatsApp sent first message in 24 hours, Facebook added 7 friends in 10 days, Slack sent 2,000 messages in workspace. Activation predicts long-term retention 10× better than signups. Best practice: define your activation event narrowly (specific action), measure conversion from signup, optimize ruthlessly. Source: Reforge, Lenny Rachitsky activation framework.
How to Grow MAU Without Inflating It
(1) Improve activation — convert more signups into actual users. (2) Improve retention — keep more existing users active each month. (3) Resurrect dormant users — re-engage users who lapsed within 60 days. (4) Drive new signups via product-led growth, paid acquisition, or content. Healthy MAU growth comes from #1-3 (improving funnel efficiency); pure paid acquisition growth without retention improvements is a leaky bucket — eventually plateaus and rolls over.
Frequently Asked Questions
What is a good DAU/MAU stickiness for SaaS?
B2B SaaS typically runs 10-20% stickiness. Daily-workflow tools (Slack, Linear) target 50%+. Periodic-use tools (tax software, payroll) might be 3-8% and still healthy. Benchmark against similar products \u2014 context matters more than absolute numbers.
How do you define 'active' user?
Define narrowly: a unique user who performed a meaningful action within the timeframe. Meaningful = something correlated with retention or value, not just opening the app. Common definitions: sent a message (chat), created a record (CRM), viewed 3+ pages (content site). Looser definitions inflate the metric meaninglessly.
Should I optimize for MAU or revenue?
Revenue, ultimately \u2014 but MAU is a leading indicator of revenue health. Growing MAU + stable ARPU = growing revenue. Stable MAU + growing ARPU = price-based growth (fragile). Falling MAU but growing revenue = monetizing churners harder, usually unsustainable. Look at both together.
What is the difference between MAU and registered users?
Registered users = total accounts ever created. MAU = unique users who took action this month. Most B2B SaaS converts only 30-50% of registered users into ongoing MAU. The gap (registered minus MAU) is the resurrection pool \u2014 users who registered but aren't engaged.
How fast should MAU grow for a healthy SaaS?
Early-stage (pre-$1M ARR): 15-25% MoM is achievable and required for venture-backed scale. Growth-stage ($1-10M ARR): 5-10% MoM is healthy. Scale-stage ($10M+ ARR): 3-7% MoM signals strong execution. Below 3% MoM at any stage suggests product-market fit or distribution issues.
Is MAU still relevant in 2026?
Yes, but increasingly contested. Some companies have shifted to 'weekly active users' (WAU) or even 'daily active customers' (DAC) for tighter signals. For SaaS, MAU still provides the most-comparable industry benchmark and aligns with monthly billing/contract cycles. For consumer products with daily-use intent, DAU is more meaningful.
