Where do your growth and churn rates actually take you?
Set new customers per month, churn and expansion. Watch 100 customers become a plateau, a rocket or a slow leak over three years, and see the ceiling your churn rate puts on your business. No account, no Stripe key, unlimited.
- No key, no signup
- Your ceiling, in one number
- Compare two scenarios
At these rates your MRR can never pass $49,261. One point less churn lifts that ceiling by 99%.

Why does the customer curve flatten even though I keep adding customers?
Because churn is a percentage of the base while acquisition is usually a fixed number. Each month you lose churn × customers; as the base grows, that loss grows until it equals what you add. At that point the base stops growing: the plateau is new customers ÷ churn rate. 10 new a month at 3% churn can never exceed 333 customers, whatever you do, unless one of the two numbers changes.
Is this a forecast of my business?
No. It compounds constant monthly rates, which real businesses never have: churn is higher in a customer's first months, acquisition is lumpy, prices change. It is a way to see the shape your current rates imply and how sensitive it is to each one. The FlowMRR app's Forecast uses your actual Stripe history instead.
Which churn should I enter?
Customer (logo) churn: the share of paying customers who cancel in a month. Revenue churn is derived from it and from expansion: with 3% customer churn and 1% expansion on the retained base, net revenue churn is about 2%. Enter a monthly rate; an annual rate of 30% is roughly 2.9% per month.
How are lifetime and LTV computed?
Average lifetime is 1 ÷ monthly churn: 3% churn means a customer stays 33 months on average. LTV is the sum of the monthly revenue over that lifetime with expansion compounded, which simplifies to ARPA ÷ (1 − (1 − churn) × (1 + expansion)). It assumes rates stay constant and ignores margins and acquisition cost.
What does percentage growth mode change?
New customers become a share of the current base instead of a fixed number. If that share exceeds churn, the base compounds exponentially and the tool shows the doubling time; if it is below churn, the base decays and the tool shows the halving time. Few companies sustain percentage growth for long; fixed acquisition is the more honest default.
