Introduction
The CAGR Calculator helps you find the Compound Annual Growth Rate of an investment. CAGR tells you how much your money grew each year, on average, over a set period of time. It smooths out the ups and downs so you can see the big picture. For example, if you invested $1,000 and it became $2,000 after five years, CAGR shows you the steady yearly rate that would get you there. This is one of the most useful numbers in investing because it lets you compare different investments fairly, even if they lasted different amounts of time.
To use this calculator, just enter your starting value, ending value, and the number of years. The tool does the math for you instantly. Whether you're looking at stocks, mutual funds, real estate, or business growth, CAGR gives you a clear and honest way to measure performance over time.
How to use our CAGR Calculator
Enter your investment details below to find the Compound Annual Growth Rate (CAGR) of your investment. The calculator will show you the steady yearly rate at which your money grew over time.
Beginning Value: Type in the starting value of your investment. This is the amount of money you first put in at the start of your investment period.
Ending Value: Type in the final value of your investment. This is how much your investment is worth at the end of the time period.
Number of Years: Enter the total number of years you held the investment. This is the time between your beginning value and your ending value.
What Is CAGR?
CAGR stands for Compound Annual Growth Rate. It is the rate at which an investment would have grown each year if it grew at a steady pace from its starting value to its ending value. In real life, investments go up and down from year to year. CAGR smooths out all those bumps and gives you one single percentage that shows the average yearly growth over a set time period.
How Is CAGR Calculated?
The formula for CAGR is:
CAGR = (Final Value ÷ Initial Value)1 / Number of Years − 1
For example, if you invested $10,000 and it grew to $25,000 over 10 years, the CAGR would be about 9.60%. This means your money grew at an average rate of 9.60% per year when compounding is taken into account. Compounding means that each year's growth builds on top of the previous year's total, not just the original amount.

CAGR vs. Simple Average Return
A simple average return just adds up the total growth and divides it by the number of years. In the example above, a $15,000 gain on a $10,000 investment over 10 years gives a simple average of 15% per year. But that number is misleading because it ignores compounding. CAGR gives you a more accurate and realistic picture of how your investment actually performed over time. This is why investors, analysts, and financial planners prefer CAGR when comparing different investments or measuring portfolio performance. If you want to see the straightforward percentage difference between two values, our Percent Change Calculator can help with that.
What Can You Use CAGR For?
- Comparing investments: You can use CAGR to see which stock, fund, or asset class grew faster over the same time period. Our ROI Calculator is another great tool for evaluating overall return on an investment.
- Setting goals: If you know your starting amount and your target amount, CAGR helps you figure out what annual return you need to reach your goal. For long-term retirement planning, you might also explore the Coast FIRE Calculator to see if your current savings can grow to meet your target without additional contributions.
- Measuring business growth: Companies use CAGR to track revenue, earnings, or customer growth over several years.
- Projecting future value: If you assume a certain CAGR, you can estimate what your investment might be worth in the future. Our Future Value Calculator lets you project exactly that, while the Present Value Calculator helps you work backward to find what a future sum is worth today.
Key Metrics Explained
The multiplier tells you how many times your money grew. A multiplier of 2.50x means your investment became 2.5 times its original size. Total growth is the overall percentage gain from start to finish. The doubling time tells you how many years it would take for your money to double at the given CAGR — a handy shortcut known as the Rule of 72, where you divide 72 by the annual rate to get an approximate doubling time. You can quickly estimate doubling time with our dedicated Rule of 72 Calculator.
Limitations of CAGR
CAGR is a useful tool, but it has limits. It assumes smooth, steady growth, which never happens in real markets. It does not show volatility or risk — two investments can have the same CAGR but very different levels of ups and downs along the way. CAGR also does not account for additional contributions or withdrawals made during the investment period. For strategies that involve regular contributions over time, a DCA Calculator can model dollar-cost averaging more accurately. For a fuller picture, investors should look at CAGR alongside other measures like standard deviation, maximum drawdown, and risk-adjusted returns. Tools like the NPV Calculator, IRR Calculator, and DCF Calculator can provide additional insight when evaluating investments with varying cash flows. If you're also tracking how interest rates affect your returns, our APY Calculator is helpful for comparing accounts with different compounding frequencies.
