MRR is the heartbeat metric of every SaaS business. Most early-stage founders underestimate the compound effect of churn and overestimate how fast growth covers losses. This calculator shows you the real math before you're deep into building.
MRR
Monthly Recurring Revenue. Your baseline: customers × price. The only number that matters before product-market fit.
ARR
Annual Recurring Revenue. MRR × 12. Used for SaaS valuations (typically 3–10× ARR for early-stage B2B).
Churned MRR
Revenue lost per month to cancellations. Even 3% monthly churn compounds to ~31% annual loss — harder to grow through than it looks.
Net MRR Growth
New revenue added minus churned revenue. Positive net MRR growth means expansion. Negative means you're shrinking.
Frequently asked questions
What is MRR and why does it matter?
MRR (Monthly Recurring Revenue) is the predictable revenue your SaaS earns each month from active subscriptions. Unlike one-time sales, MRR compounds — making it the primary metric investors and acquirers use to value SaaS businesses.
What's a good monthly churn rate?
For B2B SaaS targeting businesses, aim for under 2% monthly churn. B2C or low-price tools commonly see 3–8%. Above 10% monthly churn makes sustainable growth very difficult — you're filling a leaky bucket.
How many customers do I need to replace my salary?
It depends on your price. At $29/month, replacing a $60k salary requires ~172 customers. At $99/month, you need ~51. Use the milestone tracker above to see the exact number for your pricing.
Why does the 12-month forecast look that way?
The projection applies your growth rate and churn rate compounding each month. Even small differences in growth vs churn have a big impact after 12 months — which is why finding low-churn customers early matters more than raw growth.
What does ramen profitable mean?
The founder community uses 'ramen profitable' to mean the business generates enough to cover basic living expenses — typically $2,000–3,000/month depending on location. It marks the transition from bet to viable business.
