Frequently Asked Questions
What is MRR in SaaS?

MRR (Monthly Recurring Revenue) is the predictable revenue a SaaS business earns each month from active subscriptions. It excludes one-time payments, professional services, and non-recurring revenue.

What is the difference between MRR and ARR?

ARR (Annual Recurring Revenue) = MRR × 12. ARR is used for reporting and valuation in B2B SaaS. MRR is better for tracking month-to-month growth. ARR does not account for seasonality.

What is net new MRR?

Net New MRR = New MRR + Expansion MRR - Contraction MRR - Churned MRR. It measures how much your recurring revenue actually grew after accounting for all gains and losses in a month.

What is negative churn?

Negative churn (also called net negative MRR churn) occurs when revenue from existing customer upgrades and expansions exceeds revenue lost from cancellations and downgrades. It means your existing customer base grows without new customers.

What is the SaaS Quick Ratio?

Quick Ratio = (New MRR + Expansion MRR) / (Churned MRR + Contraction MRR). A ratio above 4 indicates a healthy, growing SaaS business. Below 1 means you are losing more than you are gaining.

What MRR growth rate is good?

Early-stage SaaS should target 15-20% monthly growth. Growth-stage companies target 10-15%. Mature companies at scale typically grow 5-10% monthly. The Rule of 40 states that growth rate + profit margin should exceed 40%.

How is SaaS valued based on MRR?

Private SaaS companies typically trade at 5-15x ARR, depending on growth rate, churn, and market. High-growth companies (50%+ ARR growth) can command 15-20x ARR. Use ARR = MRR × 12 as the starting point for valuation.
