Quick answer: CAGR formula in Excel

If you just need the formula, here it is:

=POWER(Ending_Value/Beginning_Value,1/Years)-1

Using cell references in Excel, a common version looks like this:

=POWER(C2/B2,1/D2)-1

Format the result cell as a percentage and you are done.

What CAGR means

CAGR stands for Compound Annual Growth Rate. It tells you the single annual growth rate that would turn your beginning value into your ending value over a specific period. In plain English, CAGR smooths out the bumps and gives you one clean annual rate.

That makes it useful for comparing investments, revenue growth, savings goals, or any situation where values change over multiple years.

How to calculate CAGR in Excel (step-by-step)

1) Organize your data

• Put beginning value in B2
• Put ending value in C2
• Put number of years in D2

2) Enter the formula

In E2, enter:

=POWER(C2/B2,1/D2)-1

3) Format as percentage

Select E2, then apply Percentage format in Excel. If needed, increase or decrease decimal places to match your reporting style.

4) Copy down for multiple rows

If you have a list of investments or business segments, drag the formula down. Excel will adjust the row references automatically.

Worked example

Suppose an investment grows from $25,000 to $41,000 in 6 years.

• Beginning value = 25,000
• Ending value = 41,000
• Years = 6

CAGR = POWER(41000/25000,1/6)-1 = 8.62% per year (approximately).

Even if annual returns were uneven, CAGR gives you one steady annual rate that describes the full period.

CAGR vs. average annual return

These are not the same:

• Average annual return is usually arithmetic (simple average).
• CAGR is geometric and includes the compounding effect.

For long-term planning, CAGR is typically the more reliable comparison metric.

Common mistakes to avoid

• Using zero or negative beginning values: CAGR requires a positive beginning value.
• Wrong time unit: if your period is months, convert properly (e.g., 24 months = 2 years).
• Forgetting percentage formatting: raw decimal 0.0862 should be shown as 8.62%.
• Comparing different time windows: CAGR is only meaningful when the periods are comparable.

Useful Excel variations

Alternative with exponent operator

=(C2/B2)^(1/D2)-1

This is mathematically equivalent to the POWER version.

Calculate ending value from CAGR

If you already know CAGR and want future value:

=Beginning_Value*(1+CAGR)^Years

Final thought

The best “cagr calculator excel” setup is the one you can reuse quickly. Save the formula in a template, keep clean input columns, and standardize formatting. Then each new project is a copy-paste job instead of a fresh build every time.
