Revenue Growth Rate Calculator — Methodology

Step-by-step calculation

Calculate period-over-period growth (MoM or YoY) and multi-year CAGR from any two revenue figures.

1. 1

   Pick MoM or YoY mode

   Monthly compares this month to last month. Annual compares year-over-year.

2. 2

   Enter current and previous revenue

   Same period type — both monthly figures, or both annual figures.

3. 3

   Optionally fill the CAGR section

   Starting revenue and number of years for a multi-year compound rate.

4. 4

   Read growth rate and CAGR

   Period-over-period growth and the smoothed CAGR display together. Use CAGR to compare against investor benchmarks.

Assumptions and overrides

CAGR formula assumes geometric compounding from start value to end value over N years. Doesn't reflect intra-period volatility — a business that grew 100% one year and -50% the next can have a benign CAGR.

Every region default on the calculator is editable. If your effective rate, fee, or threshold differs from the headline figure shown, type your own number into the field — the calculator recomputes instantly without leaving this page.

Review cadence and corrections

This methodology and the underlying rate defaults are reviewed at least annually, and immediately following any change to the headline rate from IRS, HMRC, or SARS. Every substantive update is recorded on the public changelog. Spotted an error? See the corrections policy for how to report it.
