I got tired of paying for expensive SaaS analytics tools when all I needed was a simple dashboard to track MRR and churn.
After 3 evenings of work, here's what I built:
The Core Metrics
- MRR (Monthly Recurring Revenue) — calculated from active customer subscriptions
- Churn Rate — rolling 30-day churn %
- ARPU — Average Revenue Per User
- LTV — Lifetime Value (assuming 24-month average retention)
- Cohort Retention — how long different join months stay
The Structure
4 Google Sheets tabs:
- Raw Data: Just paste your customer spreadsheet
- MRR Dashboard: Auto-calculated metrics with monthly trend table
- Cohort Retention: Month-by-month retention curves
- Key Insights: Natural language recommendations
The formulas are dead simple. For example, MRR is just SUMPRODUCT of active customers × plan price. Churn rate is count of recent churns divided by total customers.
The Best Part
It's available right now on Gumroad — fully filled with 30 sample rows so you can see exactly how it works before adding your own data.

(Replace [your-product-id] with the actual product ID after publishing)
Built 100% in Google Sheets — no code, no plugins, no monthly fees.
