A 20% revenue loss from churn followed by a 20% expansion gain leaves you at only 96% of your original revenue. This compounding loss means Net Revenue Retention can be misleadingly high while your logo count and long-term potential are eroding.

Churn measures the percentage of *existing* customers lost over a specific period, regardless of how many new customers were acquired. This strict definition isolates retention issues from acquisition success, providing a clear and un-muddled health metric for the customer base.
Even a seemingly acceptable 4% monthly churn will eventually cap your growth, as acquiring new customers becomes a treadmill to replace lost ones. Reducing churn to 2.5-3% is a more powerful growth lever than finding new marketing channels once you hit a plateau.
The true indicator of Product-Market Fit isn't how fast you can sign up new users, but how effectively you can retain them. High growth with high churn is a false signal that leads to a plateau, not compounding growth.
Reacting to churn is a losing battle. The secret is to identify the characteristics of your best customers—those who stay and are happy to pay. Then, channel all marketing and sales resources into acquiring more customers that fit this 'stayer' profile, effectively designing churn out of your funnel.
High customer churn creates a mathematical limit to growth. By tracking just four key metrics (new customers, churn rate, etc.), you can calculate the exact point in the future where your business will stop growing, forcing you to address retention issues proactively.
Everyone obsesses over Net Revenue Retention (NRR), but Gross Revenue Retention (GRR) is the real indicator of product health. GRR tells you if customers like your product enough to stay, period. A low GRR signals a core problem that expansion revenue in NRR might be masking.
Focus on retaining and expanding existing customer revenue (NRR) over acquiring new logos. An NRR above 120% creates compounding growth, while below 75% signals the business is dying. This metric is a truer indicator of company health than top-line growth alone.
True, scalable SaaS growth isn't just an upward line of new user acquisition. It's achieved when the user churn curve flattens out, indicating a core group of users who are activated and never leave. This creates a stable, compounding base upon which new acquisition efforts can build.
Every business has a growth ceiling where new customer acquisition is completely offset by churn. No matter how many new customers you add per month, your business will stop growing once churn equals acquisition. Plugging this 'leaky bucket' is more valuable than pouring more water in.
Monthly churn grows proportionally to your customer base, while marketing acquisition is often linear. This disparity means churn will eventually overpower growth, creating a fixed limit on how large your company can become, calculated as: New Customers per Month / Monthly Churn Rate.
