Calculate revenue growth over time and see the absolute increase and percentage change between two periods.

Your Details

Overview

This Revenue Growth Calculator helps you compare revenue from two different points in time. Enter your starting revenue, ending revenue and the number of months between them to estimate total growth, absolute change, average monthly change and compound monthly growth.

How it works

The calculator subtracts starting revenue from ending revenue to find the absolute change. It then divides that change by the starting revenue to calculate the overall percentage growth rate. It also divides the total change by the number of months to show the average monthly change, and uses a compounded growth formula to estimate the compound monthly growth rate across the full period.

How to use this calculator

  1. 1Enter the revenue from your starting period.
  2. 2Enter the revenue from your ending period.
  3. 3Add the number of months between the two periods.
  4. 4Review the revenue change and percentage growth.
  5. 5Use the monthly figures to compare performance trends over time.

Example Calculation

Starting revenue

$100,000

Ending revenue

$125,000

Period length

12

Revenue growth rate

25.00%

If revenue rises from 100000 to 125000 over 12 months, the revenue change is 25000, the overall growth rate is 25%, the average monthly change is about 2083, and the compound monthly growth rate is about 1.88%.

Frequently asked questions

What does this Revenue Growth Calculator measure?

It measures the change between starting and ending revenue, including the absolute difference, percentage growth, average monthly change and compound monthly growth rate.

Can this calculator show negative growth?

Yes. If your ending revenue is lower than your starting revenue, the calculator will show a negative revenue change and a negative growth rate.

What is the difference between growth rate and compound monthly growth rate?

The growth rate shows the total percentage change over the whole period, while the compound monthly growth rate estimates the average monthly rate that would produce the same final result.

Should I use monthly, quarterly or yearly revenue?

You can use any period as long as both revenue figures are measured consistently and the period length matches the number of months between them.

Does this calculator include profit or expenses?

No. It only looks at revenue growth. It does not account for costs, margins, taxes or profitability.
