Frequently Asked Questions
What is the difference between MRR and ARR?
MRR is Monthly Recurring Revenue — the total amount of predictable subscription revenue you earn each month. ARR is Annual Recurring Revenue, calculated as MRR multiplied by 12. ARR represents your annual revenue run rate.
How does Churn Rate affect my revenue projection?
Churn is the rate at which customers cancel subscriptions. High churn (above 5% monthly) acts like a leaky bucket, requiring you to acquire huge numbers of new customers just to stay flat. Reducing churn yields exponential revenue improvements.
What is Expansion MRR?
Expansion MRR is additional revenue generated from existing customers through upsells, cross-sells, or account upgrades. Net Negative Churn occurs when your monthly Expansion MRR is greater than your lost churn MRR.
Build Data-Driven Revenue Projections for Your SaaS Startup
Investors and operators analyze subscription business models through quantitative bottom-up metrics. Simple linear growth models fail to represent the compounding effects of customer churn and expansion revenue. This Revenue Projection Calculator allows founders to construct rigorous 12-month or 24-month revenue forecasts based on exact customer acquisition speed, retention metrics, and monthly burn limits.
How to Evaluate SaaS Growth Trajectories
Use this tool to forecast your break-even horizon. By adjusting your ARPU (Average Revenue Per User) and your churn target, you can immediately identify how price point adjustments change your cash flow needs. High-priced enterprise SaaS tools can break even on fewer customers, whereas low-priced consumer tools require extreme volume to offset standard acquisition friction.
