How to Calculate Growth Rate in Excel

Calculating growth rates is a fundamental task for financial analysis, sales tracking, and scientific data logging. While the calculator above gives you an instant answer, understanding how to implement this in Excel is crucial for managing large datasets.

The Primary Formula: CAGR

The most accurate way to calculate steady growth over multiple periods is using the Compound Annual Growth Rate (CAGR) formula. The syntax for this in Excel is:

=(Ending_Value / Beginning_Value)^(1 / Number_of_Periods) - 1

Step-by-Step Excel Implementation:

  1. Select a Cell: Click the cell where you want the percentage to appear.
  2. Type the Formula: Enter =(B2/A2)^(1/5)-1 assuming B2 is your end value, A2 is your start value, and 5 is the number of years.
  3. Format as Percent: Excel will likely output a decimal (e.g., 0.084). Press Ctrl + Shift + % to format it as 8.4%.

Using the RRI Function

Excel allows you to use a built-in function specifically for this calculation, called RRI. It calculates the equivalent interest rate for the growth of an investment.

Syntax: =RRI(nper, pv, fv)

  • nper: The number of periods (e.g., years).
  • pv: Present value (Start Value).
  • fv: Future value (End Value).

Calculating Simple Growth (Year-over-Year)

If you only need to compare two numbers (one period), the formula is simpler:

=(New_Value - Old_Value) / Old_Value

This is commonly used for Year-over-Year (YoY) or Month-over-Month (MoM) reporting.

Why Your Result Might Be #NUM! or #DIV/0!

If you encounter errors in Excel:

  • #DIV/0!: Occurs if your Start Value is 0. Growth rate from zero is mathematically undefined.
  • #NUM!: Occurs if you try to calculate the growth of a negative start value with specific fractional powers, or if the text is not recognized as a number.
