Separates the subscription question into the two margins that matter: gross margin on serving existing subscribers, and the net view after the cost of acquiring the next ones.
Enter your numbers first, then use the niche guidance below to interpret the output against saas founders, membership site operators, and subscription box businesses checking the economics under their recurring revenue..
Subscription businesses carry two different margin stories. Serving an existing subscriber is usually cheap: hosting, support, and success costs against their monthly fee produce software-style gross margins. Acquiring the next subscriber is expensive, and the net margin after sales and marketing tells you whether growth is being bought at sustainable prices.
Enter MRR as revenue, the costs of serving subscribers as cost of goods sold, and everything else, including acquisition spend, as operating expenses. The two margins the calculator returns map exactly onto the two stories, and the churn notes below explain why the same numbers can be healthy or alarming depending on retention.
Subscription COGS covers serving existing customers: hosting and infrastructure, support staff, success management, and payment processing. Gross margin is MRR minus those costs, over MRR. Operating expenses hold development, sales, marketing, and admin; the net margin after them shows whether the current growth investment level is self-funding.
A SaaS product at $40,000 MRR spends $9,000 monthly serving customers: hosting and infrastructure $3,200, support and success staffing $4,600, payment processing $1,200. Operating expenses, including development and a $11,000 acquisition budget, total $24,000.
Gross margin is 77.5 percent, in the healthy software range, and net margin is 17.5 percent while still funding growth. The reading depends on churn: at 2 percent monthly churn this is a compounding machine; at 7 percent, the acquisition budget is mostly refilling a leaking bucket and the net margin overstates health.
Interpretation assumptions: Amounts and percentage assumptions here are illustrative planning inputs, not measured industry averages. Compare results with your own costs and records; any displayed threshold bands are illustrative and do not establish typical business performance.
Costs of serving existing subscribers: hosting, support, success, and payment processing. Acquisition and development belong in operating expenses.
Churn determines how long each subscriber's margin compounds. High churn means acquisition spend buys short-lived revenue, making the same net margin much weaker.
Identically, but COGS adds product and shipping per box, so gross margins land far below software's. The two-margin reading stays the same.
