What is MRR Growth Rate?
MRR Growth Rate shows how fast your Monthly Recurring Revenue (MRR) is increasing or decreasing from one period to the next. It’s one of the clearest indicators of how quickly your SaaS is scaling.
MRR Growth Rate = ((Current MRR − Previous MRR) ÷ Previous MRR) × 100
For example, if your MRR was €50,000 last month and it’s €54,000 this month, your MRR Growth Rate is 8%.
Why MRR Growth Rate Matters for SaaS?
MRR is the core revenue engine for subscription businesses. Tracking its growth tells you if you’re actually compounding, or just treading water.
A healthy, positive growth rate means your acquisition, retention, and expansion are working together. A flat or negative rate means you’re losing revenue as fast as (or faster than) you’re adding it.
