What is Revenue Growth Rate?

Revenue growth rate is the percentage change in a company’s revenue between two periods (month-over-month, quarter-over-quarter, or year-over-year). It shows how quickly the business is expanding its revenue base and is a core input into assessing top-line momentum, scalability, and long-term value creation alongside profitability metrics like gross margin, EBITDA margin, and ROIC.

Formula

Revenue Growth Rate (%) = Revenuelater-Revenueearlier / Revenueearlier × 100

Example

A software company reports $1,000,000 in revenue last year and $1,200,000 this year. Using the formula: (($1,200,000 - $1,000,000) ÷ $1,000,000) × 100 = 20%, so the company’s revenue growth rate is 20%, which would typically be viewed as strong growth if supported by healthy unit economics (sustainable CAC, low churn, and solid margins).

How to Use the Revenue Growth Rate Calculator

This calculator helps you quickly measure how fast your revenue is growing between two comparable periods and see both the percentage growth and absolute dollar change.

Enter revenue in the earlier period

  • In the first input, type your revenue for the starting period (e.g., last year, last quarter, or last month).

Enter revenue in the later period

  • In the second input, type your revenue for the ending period that you want to compare against the earlier one.

Review the revenue growth rate

Check the change in revenue and growth profile

  • Below the growth rate, review the dollar change in revenue and the qualitative growth profile (e.g., “20%–35% (Strong)”) to quickly interpret the performance.

Reset or test alternative scenarios

  • Use the Reset button or scenarios dropdown (if available) to clear inputs or compare different what-if cases, such as slower or faster growth targets.

Frequently Asked Questions

How do I calculate revenue growth rate between two periods?

Subtract earlier-period revenue from later-period revenue, divide by earlier-period revenue, then multiply by 100 to express it as a percentage.

What’s the difference between revenue growth rate and change in revenue?

Change in revenue is the absolute dollar increase or decrease, while revenue growth rate shows that change relative to the starting revenue as a percentage, which makes it easier to compare growth across time periods or businesses of different sizes.

Is a 20% revenue growth rate considered good?

In many SaaS and high-growth businesses, 20%–35% annual growth is typically considered strong, but you should always interpret it alongside profitability, churn, margins, and how repeatable the growth channels are.

Can I use this calculator for monthly or quarterly revenue, not just yearly?

Yes. As long as both revenue inputs cover the same time length (month vs month, quarter vs quarter, year vs year), the formula works the same and the growth rate will be valid.
