Growth Rate (%) = ((Current MRR - Previous MRR) / Previous MRR) × 100About this tool
Tracking Month-over-Month (MoM) MRR growth rate allows subscription founders to measure the speed of their revenue expansion and evaluate the real-world impact of product launches, marketing campaigns, and pricing updates. In early-stage SaaS, compounding growth is the single most scrutinized metric by angel investors and accelerators: sustaining strong month-over-month growth turns a modest $5,000 MRR product into a $25,000+ MRR business within twelve months. In addition to simple linear growth, calculating your annualized compound growth trajectory helps founders set defensible hiring plans and manage runway. Use this calculator at the end of every billing cycle to measure your net monthly growth velocity.
How It Works
- 1Input your previous period's MRR (e.g. previous month ending balance).
- 2Input your current period's MRR.
- 3Review your percentage growth rate, net dollar increase, and annualized compound growth trajectory.
Formula & Math
Transparent LogicGrowth Rate (%) = ((Current MRR - Previous MRR) / Previous MRR) × 100
Worked Practical Example
A B2B SaaS ends January with $18,000 MRR and finishes February at $21,600 MRR.
Calculation / Steps
(($21,600 - $18,000) / $18,000) × 100 = ($3,600 / $18,000) × 100 = 20.00%
Expected Result
20.00% MoM MRR growth rate (+$3,600 net new MRR).
Frequently Asked Questions
What is considered a strong MoM MRR growth rate for early-stage SaaS?+
Growth rates fall naturally as the base grows: adding $2,000 MRR is 40% growth at $5,000 and 2% at $100,000. Instead of chasing a universal percentage, watch your net new MRR each month and check whether it is rising.
What is Compound Monthly Growth Rate (CMGR)?+
CMGR measures the steady monthly growth rate required to grow from a starting revenue figure to an ending figure across multiple months.
Why is high growth dangerous if churn is also high?+
High growth masking high churn creates a 'growth trap': as your base grows, replacing churned accounts eventually consumes your entire acquisition pipeline.
