Calculator guide
Enter monthly price, active and new subscribers, payment-processing rates, Stripe Billing rate, monthly churn and other recurring costs.
Gross MRR is not cash profit. Payment fees, Billing fees, refunds, tax, support, infrastructure and acquisition costs may materially reduce retained revenue.
Churn is applied to the current active subscriber base. The next-month estimate adds new subscribers and subtracts expected churned subscribers.
Use cohort-level retention and actual Stripe invoices when moving from a simple forecast to a financial plan.
Formula
Net MRR = monthly price × active subscribers − payment fees − Billing fees − other monthly costs
