What is the Revenue Growth Rate Calculator?
The Revenue Growth Rate Calculator shows how quickly a startup's revenue is increasing or decreasing over a defined period. It converts the change between two revenue periods into a percentage so you can compare performance across quarters or years.
How does it work?
Enter the prior period's revenue and the current period's revenue. The calculator subtracts the older value from the newer value, divides by the older value, and multiplies by 100 to express the result as a percentage.
Formula
((current revenue - previous revenue) / previous revenue) x 100
How the calculation works
How the calculation works
- 1Start with your previous period revenue, the base you compare against.
- 2Subtract previous revenue from current revenue to find the absolute change.
- 3Divide the change by the previous period revenue.
- 4Multiply by 100 to express the result as a percentage growth rate.
Worked example
Worked Example
Bloomr Analytics, a fictional B2B SaaS company, wants to report its quarterly growth to investors. Last quarter it earned $100,000 and this quarter it earned $125,000.
- 1Subtract previous revenue from current revenue: 125000 - 100000 = 25000
- 2Divide the change by previous revenue: 25000 / 100000 = 0.25
- 3Multiply by 100 to convert to a percentage: 0.25 x 100 = 25%
Result
Bloomr Analytics grew 25% between the two periods, adding $25,000 in revenue, a strong pace for an early-stage SaaS company.
Interpretation guide
How to read your result
Revenue is growing slower than most venture-backed SaaS companies, which may signal weak product-market fit or a maturing market.
Investigate why growth is slowing, review retention and expansion, and consider whether the product or go-to-market needs a refresh.
A respectable, common pace for SaaS companies that have moved past hypergrowth and are scaling operations.
Keep optimizing sales and marketing efficiency while protecting gross margin as growth matures.
Solid hypergrowth typical of early-stage SaaS companies with strong product-market fit.
Maintain momentum by doubling down on winning channels and investing in retention to protect the base.
Outstanding growth for a company under $10M ARR, the profile investors reward with premium valuations.
Use this window to scale aggressively, but watch burn and unit economics so growth remains efficient.
Benchmarks
SaaS revenue growth benchmarks by stage (year-over-year)
| Metric | Typical | Strong |
|---|---|---|
| VC-backed SaaS (all stages) | 20-40% | 40%+ |
| Early stage (under $10M ARR) | 40-60% | 60%+ |
| Growth stage ($10M+ ARR) | 15-25% | 25%+ |
Common mistakes
- - Comparing revenue periods with different business models or seasonality
- - Using net revenue without removing refunds or returns
- - Forgetting that a low base period can create a very high growth percentage
Practical tips
Practical tips
Use recurring revenue (MRR or ARR), not one-time revenue, when measuring SaaS growth so the number is comparable across periods.
Always compare the same number of days or months on both sides; a 5-week quarter versus a 4-week quarter distorts the rate.
Split growth into new customer revenue and expansion revenue from existing customers to see where the momentum really comes from.
Beware a small base: growing from $5,000 to $10,000 is 100% growth but not proof of product-market fit.
Review growth monthly to catch slowdowns early, but evaluate year-over-year to remove seasonality.
Pair the growth rate with gross margin and burn to confirm growth is being bought at a sustainable price.
When should you use it?
- - Reviewing monthly or quarterly growth trends
- - Comparing performance across different growth periods
- - Supporting board updates and investor reporting
- - Tracking whether revenue growth is accelerating or slowing
Benefits
- - Shows growth in a simple percentage that is easy to compare
- - Helps founders spot momentum changes early
- - Supports forecasting and goal-setting conversations
Use cases
- - Quarterly founder reviews
- - Investor update decks
- - Sales and marketing planning
Step-by-step example
Pull the previous and current revenue figures from your bookkeeping or analytics records. Subtract the prior revenue from the current revenue to find the absolute change. Divide that difference by the previous revenue and multiply by 100 for the growth rate.
Real-world example
A startup that earned $100,000 last period and $125,000 this period has a revenue growth rate of 25%. That means revenue increased by one-quarter over the comparison period.
