What is a Subscription Revenue Calculator?
Recurring billing lives and dies by two numbers: how much each subscriber pays and how many stay. MRR and ARR capture the first; churn governs the second. This tool combines them, compounding the base month over month by growth minus churn, so you can watch a healthy-looking MRR quietly shrink under churn — or grow when new sign-ups outrun cancellations.
Use it to model a price change, see how much growth you need just to offset churn, or set a realistic year-end revenue target before you plan spend against it.
❓ Frequently Asked Questions
How are MRR and ARR calculated?
Monthly recurring revenue (MRR) is your active subscribers multiplied by the monthly price. Annual recurring revenue (ARR) is simply MRR times twelve. Both assume a single plan price — for mixed tiers, run each tier separately and add the results.
How does churn affect the projection?
Each month the subscriber base changes by a net rate of growth minus churn, compounding on the previous month. With 5% monthly churn and no growth, you keep 95% of subscribers each month, so revenue erodes steadily unless new sign-ups replace those who leave.
What does the growth percentage do?
It's optional gross monthly growth from new subscribers. The projection applies (growth − churn) each month, so setting growth equal to churn holds the base flat, and setting it higher compounds the base upward over the twelve months.
Is this a revenue guarantee?
No. Real subscription businesses see variable churn, upgrades, downgrades, failed payments, and seasonality. Treat the projection as an informational estimate — not financial advice.
