Revenue growth rate
Revenue growth rate measures the percentage increase in revenue over a specified period. It is the most watched metric for assessing whether a business is expanding, stagnating, or declining, and it directly drives company valuation.

What is revenue growth rate?
Revenue growth rate measures how quickly a company's top line is expanding. It can be calculated month over month, quarter over quarter, or year over year. Year-over-year (YoY) growth is the most commonly reported because it eliminates seasonal effects.
For SaaS companies, revenue growth rate is the primary driver of valuation multiples. High-growth SaaS companies command premium multiples (10-20x ARR) while slower-growing companies trade at more modest multiples (3-7x ARR). This creates a powerful incentive to maintain growth, but growth at any cost is not the goal. Growth must be efficient, which is why metrics like the Rule of 40, burn multiple, and magic number exist to balance growth rate against profitability.
Growth rate naturally decelerates as the revenue base grows. Doubling from 1M to 2M ARR (100% growth) is structurally easier than doubling from 50M to 100M ARR. This is why growth rate benchmarks are segmented by company stage, and why the absolute growth rate matters less than whether the company is growing at the expected rate for its size.
How to calculate revenue growth rate
Year-over-year growth rate:
YoY Growth = (Revenue This Year - Revenue Last Year) / Revenue Last Year x 100
Month-over-month growth rate:
MoM Growth = (Revenue This Month - Revenue Last Month) / Revenue Last Month x 100
Compound monthly growth rate (CMGR) provides a smoothed growth rate over a period:
CMGR = (Ending Revenue / Beginning Revenue) ^ (1 / Number of Months) - 1
CMGR is particularly useful for startups with volatile monthly growth, as it provides a cleaner picture of the underlying growth trajectory than individual monthly figures.
Revenue growth in a metric tree
The tree decomposes revenue growth into its four drivers: new customer revenue, expansion revenue, retention, and losses. This reveals the quality of growth. Growth driven primarily by new customers is expensive (requires acquisition spend). Growth driven by expansion and retention is efficient and sustainable. The healthiest companies achieve growth through a combination of efficient new customer acquisition and strong net revenue retention.
Growth rate benchmarks
| ARR range | Top quartile YoY growth | Median YoY growth |
|---|---|---|
| Under 1M | 300%+ | 100-200% |
| 1M to 10M | 100-200% | 60-100% |
| 10M to 50M | 60-100% | 40-60% |
| 50M to 100M | 40-60% | 25-40% |
| 100M+ | 25-40% | 15-25% |
How to accelerate revenue growth
Expand into new markets
New geographies, customer segments, or use cases increase the addressable market and provide new sources of customer acquisition.
Increase net revenue retention
NRR above 120% means the existing customer base is growing by 20% annually without any new customers. This is the most efficient growth source.
Launch new products
Additional products or modules create cross-sell opportunities and increase the revenue potential from each customer.
Move upmarket
Larger deals increase average contract value. Closing half as many deals at 3x the ACV still produces 50% more revenue.
Common mistakes
- 1
Celebrating MoM growth without annualising
10% month-over-month growth sounds modest but compounds to 214% annual growth. Conversely, 2% MoM is only 27% annually. Always understand the annualised rate.
- 2
Ignoring the quality of growth
Growth driven by deeply discounted deals, unsustainable marketing spend, or non-recurring revenue may not persist. Track growth alongside retention rate, margin, and efficiency metrics.
- 3
Not comparing to relevant benchmarks
A 50% growth rate is exceptional for a 100M company but below average for a 5M company. Always benchmark against companies of similar size and stage.

ARR = MRR x 12
Annual recurring revenue (ARR) is the annualised value of a company's recurring subscription revenue. It is the primary metric used to measure the scale and growth trajectory of SaaS businesses, and it directly drives enterprise valuations.
Rule of 40
Growth + Profit benchmark
SaaS MetricsMetric Definition
Rule of 40 Score = Revenue Growth Rate (%) + Profit Margin (%)
The Rule of 40 states that a healthy SaaS company's combined revenue growth rate and profit margin should equal or exceed 40%. It balances the tension between growth and profitability, providing a single benchmark for overall business health.
