Calculate Compound Annual Growth Rate for any investment or metric
CAGR stands for Compound Annual Growth Rate. It's the rate at which an investment or metric grows from its beginning value to its ending value, assuming it compounds annually over the period. CAGR smooths out the ups and downs of year-to-year growth and gives you a single, clean number that represents the steady rate at which something would need to grow each year to get from point A to point B.
Think of it this way โ if an investment was worth $10,000 in 2019 and grew to $25,000 by 2024, the journey probably wasn't a perfectly smooth 20% increase every year. There were likely good years and bad years. CAGR doesn't care about the bumpy path โ it just tells you the equivalent smooth annual rate that gets you the same end result.
CAGR is widely used in investing, business analysis, and financial reporting because it allows meaningful comparisons across different time periods and different assets. It's the standard metric for evaluating investment performance, comparing mutual funds, analyzing business revenue growth, and projecting future values.
Simply enter the initial value โ the starting amount of your investment or metric. Then enter the final value โ what it grew to by the end of the period. Enter the number of years between the two values. The calculator instantly shows you the CAGR, total growth percentage, and total gain in dollar terms.
The reverse CAGR section works the other way โ enter an initial value, a target CAGR, and a number of years to find out what the investment would be worth at the end of that period. This is useful for projecting future portfolio values based on expected returns.
Simple growth rate just divides the total gain by the initial value and gives you the overall percentage change. CAGR goes further by annualizing that growth to show the per-year equivalent rate. For comparing investments held over different time periods, CAGR is far more useful because it normalizes everything to an annual basis.
For example, Investment A doubled in 3 years and Investment B tripled in 7 years. Simple growth says B grew more (200% vs 100%). But CAGR tells a different story โ Investment A had a CAGR of about 26%, while Investment B had a CAGR of about 17%. Investment A was actually growing faster on an annualized basis.
This depends entirely on the context โ what you're measuring, the time period, and the risk involved. For stock market investments, the S&P 500 has historically delivered roughly 10% CAGR before inflation and around 7% after inflation over long periods. Many investors consider anything above 10-12% annual return to be strong performance for a diversified portfolio.
For individual stocks or growth companies, CAGRs of 20-30%+ are possible but come with significantly higher risk and volatility. For safer assets like bonds or savings accounts, CAGRs of 3-6% are more typical. For real estate, historical CAGRs have averaged around 4-6% in most markets, though this varies significantly by location and time period.
For business revenue growth, a CAGR above 20% is generally considered high growth. Established large companies often target 5-10% revenue CAGR as sustainable growth. Startups and early-stage companies may show much higher CAGRs from a small base, which isn't necessarily meaningful until the numbers become significant.
CAGR has real limitations worth understanding. It assumes smooth, consistent growth โ which rarely happens in reality. An investment that dropped 40% one year and then gained 80% the next looks very different in practice than a smooth 14% CAGR suggests.
CAGR also doesn't account for cash flows in or out during the period. If you added money to an investment partway through, CAGR doesn't capture that accurately. For situations with multiple cash flows, Internal Rate of Return (IRR) is a more appropriate metric.
Additionally, CAGR doesn't tell you anything about volatility or risk. Two investments with identical CAGRs could have dramatically different risk profiles โ one might have been a smooth ride while the other went through stomach-churning swings. Always consider risk alongside return when evaluating investments.
