Revenue growth rate measures the percentage change in a company’s revenue between two periods. SaaS businesses use it to understand whether sales and recurring revenue are increasing or decreasing over time. The result depends on which revenue measure is used, such as total recognized revenue, MRR, or ARR, and whether the periods are comparable.
Revenue Growth Rate Formula
Revenue Growth Rate (%)
((Current-period revenue − Previous-period revenue) ÷ Previous-period revenue) × 100
Example: If a SaaS company’s quarterly revenue increases from $400,000 to $460,000, its growth rate is (($460,000 − $400,000) ÷ $400,000) × 100 = 15% quarter over quarter.
Always label the period comparison, such as month over month, quarter over quarter, or year over year. If the starting-period revenue is zero, the percentage growth formula is undefined; use an absolute change or another suitable explanation instead.
Revenue Growth vs. MRR or ARR Growth
| Metric | What it measures | Important note |
|---|---|---|
| Total revenue growth | Change in recognized revenue over a period | May include services, usage, and other revenue depending on the business |
| MRR growth | Change in normalized monthly recurring revenue | Uses a defined recurring revenue metric rather than all recognized revenue |
| ARR growth | Change in annual recurring revenue | Often used for subscription run-rate analysis and may not equal recognized annual revenue |
| Customer growth | Change in the number of customers | Customer count can rise while average revenue per customer falls |
Why Revenue Growth Rate Matters
- Tracks business momentum: It shows how revenue changes over time.
- Supports planning: Consistent comparisons can help teams model hiring, infrastructure, and investment needs.
- Highlights underlying drivers: Growth can come from new customers, expansion, pricing, or one-time revenue, so teams should separate the components.
- Enables trend analysis: Year-over-year comparisons can help account for recurring seasonal patterns.
How to Analyze Revenue Growth
- Use consistent definitions. Keep revenue recognition, currency conversion, discounts, and reporting boundaries consistent.
- Choose a relevant comparison. Month-over-month results can show recent movement, while year-over-year comparisons may better account for seasonality.
- Break down the drivers. Separate new sales, expansion, contraction, churn, pricing changes, and one-time items where possible.
- Compare growth with retention. Rapid acquisition may hide a weak existing customer base.
- Review margins and cash flow. Revenue growth does not automatically mean the business is profitable or well funded.
- Investigate unusual changes. Check for billing changes, large contracts, credits, accounting adjustments, or data errors before drawing conclusions.
Common Mistakes
- Comparing periods of different lengths.
- Mixing recognized revenue with MRR or ARR without labeling the difference.
- Using percentage growth when the starting value is zero or extremely small without explaining the limitation.
- Assuming a higher growth rate always means better business health.
- Ignoring inflation, currency effects, acquisitions, or one-time revenue when they materially affect comparability.
Frequently Asked Questions
What is a good SaaS revenue growth rate?
There is no single benchmark for all SaaS companies. Growth depends on company stage, market, pricing, customer segment, and business model. Compare similar companies or periods and assess retention, margin, and cash needs alongside growth.
Can revenue growth rate be negative?
Yes. A negative rate means current-period revenue is lower than the previous period under the chosen measure.
Should revenue growth be measured monthly or annually?
Both can be useful. Monthly views are more responsive but can be volatile; year-over-year views can help account for seasonality. Choose the period that matches the decision.
Does revenue growth include new customers only?
No. Total revenue growth can reflect new customers, expansion, pricing, recurring revenue changes, services, and other revenue sources. Break down the drivers to understand what changed.
