Subscription growth planning
MRR & Churn Forecast Calculator
Forecast SaaS subscription revenue, customer growth, MRR, and ARR run rate over 12 months using ARPA, new acquisitions, monthly churn, and expansion rates.
Forecasts run locally; shared links contain only the numbers you choose.
How is the forecast ordered?
Each month starts with current customers, subtracts churn, adds new customers, calculates base MRR, then applies expansion. ARR run rate is ending MRR multiplied by 12.
