How to Use This Tool

Follow these steps to calculate accurate DAU metrics for your business:

  1. Select your business type from the dropdown to load relevant industry benchmarks.
  2. Enter your total Monthly Active Users (MAU) – this is the number of unique users who engaged with your platform in the last 30 days.
  3. Input your average daily new user count, sourced from your analytics dashboard.
  4. Add your retention rates for Day 1, Day 7, and Day 30 – these are standard retention metrics tracked by most analytics tools.
  5. Click the Calculate button to view your DAU breakdown, or Reset to clear all fields.
  6. Use the Copy button to save your results to your clipboard for reports or team sharing.

Formula and Logic

This calculator uses standard SaaS and e-commerce engagement metrics to estimate DAU and related KPIs:

  • Estimated DAU: Calculated as (Daily New Users) + (MAU × Average Retention Rate). Average retention is the mean of your Day 1, Day 7, and Day 30 retention rates.
  • Stickiness Ratio: (DAU ÷ MAU) × 100. This measures how often users return to your platform, with higher percentages indicating stronger engagement.
  • Estimated WAU: DAU × 7, a simplified projection of weekly active users based on daily engagement.
  • Growth Potential: Projects DAU increase if all retention rates improve by 5 percentage points, helping you prioritize retention campaigns.

Industry benchmarks are sourced from aggregate business performance data for each selected business type.

Practical Notes

For accurate results, align your input data with your business's reporting standards:

  • MAU should exclude inactive users who have not logged in or made a purchase in 30+ days, depending on your business model.
  • Retention rates should be calculated for users who completed a core action (e.g., made a purchase, logged in, posted content) not just passive visits.
  • SaaS businesses typically target a stickiness ratio of 20% or higher, while e-commerce stores average 10-15% for repeat buyers.
  • Use Day 30 retention to assess long-term product-market fit: rates below 5% indicate high churn that requires immediate attention.
  • Marketplace platforms should track DAU for both buyers and sellers separately to identify imbalances in supply and demand.

Why This Tool Is Useful

DAU is a core engagement metric for all digital businesses, but manual calculations often lead to errors or incomplete data. This tool:

  • Eliminates manual math errors by automating DAU, WAU, and stickiness calculations.
  • Provides industry benchmarks to help you assess if your engagement rates are above or below average for your niche.
  • Quantifies the impact of retention improvements, helping you justify budget allocation for user retention campaigns.
  • Generates shareable results for investor reports, team meetings, or performance reviews.
  • Supports all common digital business models, from SaaS to e-commerce to social platforms.

Frequently Asked Questions

What is a good DAU/MAU stickiness ratio for e-commerce?

E-commerce businesses typically see stickiness ratios between 10-15% for general stores, and up to 20% for subscription-based or loyalty program-driven brands. Ratios below 8% indicate low repeat purchase rates, which may require improved email marketing or personalized recommendations.

How do I track retention rates for my business?

Most analytics tools (Google Analytics, Mixpanel, Amplitude) automatically calculate retention rates. For manual tracking, divide the number of users who return on Day 1, Day 7, or Day 30 by the number of new users acquired on the cohort start date.

Why is my DAU lower than my daily new user count?

This usually indicates very low retention: if few users return after their first visit, your DAU will be roughly equal to your daily new user count. Improve onboarding flows, send push notifications, or offer first-time user discounts to boost short-term retention.

Additional Guidance

Use this tool alongside other business metrics to get a full picture of performance:

  • Compare DAU trends to your marketing spend to calculate customer acquisition cost (CAC) per active user.
  • Track DAU growth alongside revenue to ensure engagement gains are translating to sales.
  • Segment your DAU by user type (free vs paid, new vs returning) to identify high-value user groups.
  • Recalculate DAU monthly to track the impact of product updates or marketing campaigns on engagement.
