MRR is four movements, not one number
Monthly recurring revenue only informs when decomposed: new MRR from new customers, expansion from existing ones, contraction from downgrades, and churned MRR from departures. The same headline growth can be a healthy engine or a leaky bucket refilled at increasing cost, and only the decomposition tells you which.
Watch the ratio of expansion to churned MRR most: a business where existing customers grow faster than they leave, net revenue retention above one hundred percent, compounds even when new sales stall, and that quality is what buyers of SaaS companies actually price.
Churn without flattery
Measure both logo churn, customers lost, and revenue churn, MRR lost, because losing three tiny accounts and losing your largest are different events wearing the same percentage. Cohort the number: churn among customers in their first ninety days is an onboarding verdict, while churn at month eighteen is a value verdict, and they have different fixes.
The standard flatteries: annual contracts hiding churn until renewal cliffs arrive together; averaging across a growing base so the denominator dilutes the loss; and counting pauses as retained. Small print in your own favor is still small print.
CAC payback is the survival metric
Customer acquisition cost, fully loaded with salaries and tools rather than just ad spend, divided into the gross margin a customer contributes monthly, gives payback in months: how long capital is trapped in each acquisition. Small companies live and die on this number, because payback beyond a year on a thin balance sheet means growth itself consumes the runway.
Lifetime value models flatter easily at SMB scale, resting on churn assumptions with two data points. Payback months, measured on real margin, is the metric that keeps a self-funded SaaS honest, and the one to quote when anyone asks how growth is going.
The Cockpit computes them from your numbers
The Financial Cockpit on the Tools Desk tracks MRR movements, churn both ways and payback from your actual figures, so the decomposition is a view rather than a quarterly spreadsheet project. Velora writes the plain-language delta on what moved and why it matters.
It shares the workspace with the pipeline that creates the customers and the invoicing that collects from them, which is what keeps the numbers reconciled. From the Plus membership.
Frequently asked questions
What SaaS metrics matter most for a small company?
MRR decomposed into new, expansion, contraction and churn; both logo and revenue churn, cohorted; and CAC payback in months on fully loaded costs. Those three read the business honestly.
What is a good churn rate?
Lower is better and context rules, but the operational question is direction and cohort: early churn indicts onboarding, late churn indicts value. Net revenue retention above one hundred percent is the mark of a compounding base.
Why use CAC payback instead of LTV?
LTV rests on churn assumptions small datasets cannot support; payback months on real gross margin measures how long capital is trapped per customer, which is what a self-funded company actually feels.
