CAGR Calculator

A CAGR Calculator helps you estimate the average annual growth rate of an investment or other value over a specific period. CAGR stands for Compound Annual Growth Rate. It provides a simple way to describe how much a value would have grown each year if it had increased at a steady compounded rate.

What Is CAGR?

CAGR is a measure of annualized growth between a beginning value and an ending value over a set number of years. It is commonly used to compare the growth of investments, revenue, sales, business performance, and other financial figures over time.

CAGR assumes that growth is compounded and occurs at a consistent annual rate for the entire period. In real situations, however, growth is often uneven from one year to another.

How to Calculate CAGR

The standard CAGR formula is:

CAGR = (Ending Value / Beginning Value)^1/n - 1

Here, the Beginning Value is the starting amount, the Ending Value is the final amount, and n represents the number of years in the period.

The result is usually multiplied by 100 to express CAGR as a percentage.

CAGR Example

Suppose an investment grows from $10,000 to $15,000 over five years. Using the CAGR formula:

CAGR = (15,000 / 10,000)^1/5 - 1

The result is approximately 8.45%. This means the investment had a compound annual growth rate of about 8.45% over the five-year period.

This does not mean the investment actually increased by 8.45% every year. The value may have gone up or down considerably during individual years. CAGR simply expresses the overall growth as an equivalent annual compounded rate.

Why Use a CAGR Calculator?

Calculating CAGR manually can be inconvenient when you are comparing several values or longer time periods. A CAGR calculator can provide a quick result once you enter the beginning value, ending value, and number of years.

It can be useful for reviewing investment performance, comparing business growth, analyzing revenue changes, or understanding how a value has changed over time.

CAGR vs. Average Annual Growth

CAGR and a simple average annual growth rate are not the same. CAGR accounts for compounding and considers the beginning and ending values over the complete period. A simple average may only calculate the arithmetic average of yearly growth rates.

For this reason, CAGR is often more useful when you want one annualized figure that represents the overall growth between two points in time.

What CAGR Does Not Show

CAGR is useful for summarizing long-term growth, but it does not show the path taken to reach the ending value. Two investments can have the same CAGR while having very different yearly results.

For example, one investment might grow steadily while another experiences large gains and losses before reaching the same final value. Both could have the same CAGR even though their risk and performance patterns are very different.

When to Use CAGR

You can use CAGR when you have a starting value, an ending value, and a defined time period. It is especially useful for comparing growth over multiple years when you want to express the overall change as an annualized rate.

CAGR can be applied to investments, company revenue, sales, market size, customer growth, or other measurable values that change over time.

Important Things to Remember

CAGR is a mathematical measure of historical or assumed growth. It does not predict future performance and does not account for volatility, fees, taxes, deposits, withdrawals, or other factors unless they are already reflected in the beginning and ending values.

When comparing investments, consider CAGR alongside risk, fees, volatility, and the period being analyzed. A higher historical CAGR does not guarantee a higher future return.
