It calculates customer churn rate (customers lost ÷ starting customers) or revenue churn rate (MRR lost ÷ starting MRR) from your inputs. It then derives retention rate, estimated customer lifespan, annual churn, and estimated revenue impact — all as illustrative figures based on your data.
Use your actual subscriber counts and cancellation numbers from your billing system — not estimates. The customer churn method suits subscription businesses tracking headcount. Revenue churn is better for businesses with varied pricing tiers where a single cancellation may not represent average revenue lost.
This tool uses a simple period-over-period formula that may differ from how your billing platform calculates churn. Different methodologies (e.g. excluding new customers added mid-period, handling trial-to-paid conversions, or accounting for pauses) produce meaningfully different results. Always verify with your billing system.
Churn rate measures the percentage of customers or revenue a subscription business loses over a given period. It is one of the most important health metrics for any recurring revenue business — a high churn rate means revenue and customers are leaving faster than they are being acquired, while low churn extends customer lifetime and improves unit economics. However, churn is also one of the most frequently miscalculated metrics, with different methodologies producing meaningfully different results.
Customer churn counts the percentage of subscribers who cancel, treating each subscriber equally. Revenue churn (or MRR churn) weights cancellations by their revenue value, which is more meaningful for businesses with varied pricing tiers. A business that loses mostly low-tier subscribers may have high customer churn but relatively low revenue churn — and vice versa. Both metrics are useful for different purposes, and neither is universally "correct."
Involuntary churn — customers who are cancelled because their payment failed rather than because they chose to leave — is often the largest single source of churn for subscription businesses. It is also the most recoverable. Better payment infrastructure, including card updater services, retry logic, and dunning sequences, can recover a significant portion of failed payments. QuadraPay is a payment solutions reseller — we can refer subscription businesses to acquiring partners with these capabilities. No outcomes are guaranteed.
A significant portion of subscription churn comes from failed payments. We connect businesses to acquiring partners with subscription billing infrastructure that may help reduce involuntary churn.
