Forecasting Compounding Subscription Growth
Unlike one-time transactional sales, subscription revenue compounds over multi-year horizons. Modeling subscriber acquisition alongside churn retention rate allows founders to project cash flow runway and investor valuation milestones.
Frequently Asked Questions
How does the Subscription Revenue Calculator work?
The calculator models month-by-month compounding subscriber addition, churn, expansion, and ARPU over a 60-month horizon 100% in your browser.
What is ARPU (Average Revenue Per User)?
ARPU is the average monthly recurring revenue generated per active subscription account.
Why does subscription revenue compound non-linearly?
Because recurring revenue persists month-to-month, adding new customers on top of retained existing customers creates compounding exponential growth curves.
Is my forecasting data stored on any server?
No. The calculator operates 100% locally in your web browser. No company numbers leave your device.
How does expansion revenue extend long-term subscription growth?
Expansion revenue from upsells and seat additions offsets customer churn, enabling negative net churn where revenue grows automatically over time.
What is the 5-year ARR milestone for successful SaaS companies?
Successful venture-backed SaaS companies target $10M+ ARR by Year 4 or Year 5.
Can I model both monthly and annual subscription plans?
Yes. Annual plans can be averaged into monthly recurring contributions.
