Why Use the MRR Growth Rate Calculator?
MRR Growth Rate tracks monthly recurring revenue trajectory while dissecting gross addition drivers (new sales & account expansion) versus revenue leakage (downgrades & customer churn).
Having accurate, real-time insights into this metric helps SaaS founders, CFOs, and growth teams optimize capital allocation, protect operating runway, and achieve top-tier venture scalability.
Mathematical Formula & Derivation
The mathematical derivation for this financial metric is expressed as:
\(\text{Net New MRR} = \text{New MRR} + \text{Expansion MRR} - \text{Contraction MRR} - \text{Churned MRR}\) \n\(\text{MoM Growth Rate \%} = \frac{\text{Net New MRR}}{\text{Beginning MRR}} \times 100\%\) \n\(\text{Net Revenue Retention (NRR) \%} = \frac{\text{Beginning MRR} + \text{Expansion} - \text{Contraction} - \text{Churn}}{\text{Beginning MRR}} \times 100\%\)
Where all input values are evaluated over a standardized monthly or annual accounting period.

Frequently Asked Questions
What is Net New MRR?
Net New MRR represents the net change in monthly recurring revenue added during the month after accounting for new customer additions, upgrades, downgrades, and lost accounts.
What is a good MoM MRR growth rate benchmark?
Early-stage SaaS startups ($100k-$1M ARR) target 10%-15%+ MoM growth. Growth-stage startups ($1M-$10M ARR) target 5%-8% MoM growth.
What is Net Revenue Retention (NRR)?
NRR measures recurring revenue retained from existing customers over a period, including expansion upgrades minus churn and contraction.
What is a top-tier NRR benchmark?
Top-tier Enterprise SaaS companies achieve 110%-130%+ NRR, indicating that revenue grows over time even with zero new customer acquisition.
