Calculator guide
Who this calculator is for
Global investors, financial analysts, startup founders, and marketers looking to compare investment performance or business growth across different time periods.
Calculate the steady annualized growth rate (CAGR) required to get from a beginning value to an ending value over a specific number of years, while adjusting for inflation and taxes.
Formula used
CAGR = (Ending value / Beginning value)^(1 / years) - 1. Inflation Adjusted CAGR = [(1 + Nominal CAGR) / (1 + Inflation Rate)] - 1.
The calculator keeps the math visible so users can understand what changed when they adjust rate, time, contribution, tax rate or loan amount.
Example: $10,000 grows to $25,000 in 5 years
How to get a useful result
For the best estimate, use realistic rates, verify lender or tax assumptions, and run at least one conservative scenario. This makes the page more useful than a bare calculator and helps visitors stay longer because they can compare outcomes instead of leaving after one number.
Frequently asked questions
CAGR stands for Compound Annual Growth Rate. It is the steady annual growth rate that links a starting value to an ending value over time, assuming profits are reinvested.
Divide the ending value by the beginning value. Raise that result to the power of 1 divided by the number of years. Then subtract 1 and multiply by 100 to get the percentage.
No. An average annual return is a simple arithmetic average. CAGR uses a geometric average to account for the effects of compounding, making it a much more accurate measure of long-term investment performance.
Yes. If the ending value of an investment is lower than the beginning value, the CAGR will be a negative percentage, representing an annualized loss.
Historically, the US stock market (S&P 500) has returned a nominal CAGR of around 9% to 10% per year over long time horizons. Anything consistently above 10% is generally considered excellent.
To find the Real CAGR, you subtract the inflation rate using the Fisher Equation: [(1 + Nominal CAGR) / (1 + Inflation Rate)] - 1. Our calculator automates this math for you.
Because of volatility drag. If you lose 50% one year and gain 50% the next, your simple average return is 0%, but your actual portfolio value is down 25%, resulting in a negative CAGR.
CAGR is used for a single lump-sum investment measured from point A to point B. XIRR (Extended Internal Rate of Return) is used when you make multiple deposits and withdrawals at irregular dates over time.
IRR (Internal Rate of Return) calculates the discount rate that makes the net present value of all cash flows equal to zero. It is used to evaluate project profitability. CAGR is a simpler formula that only looks at the start and end values.
You should not use CAGR if you are making regular monthly contributions (use a SIP or Investment calculator instead), or if the investment is highly volatile and you need to understand the risk (drawdowns) taken to achieve the return.
Taxes reduce your final ending value. A tax-adjusted CAGR calculates your annualized growth rate after deducting capital gains taxes from your total profit.
The growth multiple is simply your ending value divided by your beginning value. For example, if a $10,000 investment grows to $30,000, your growth multiple is 3.0x.
Yes, the standard CAGR calculation assumes that any cash flow generated by the investment (like dividends or interest) is reinvested back into the portfolio and reflected in the final ending value.
Technically yes, by using a fraction (like 0.5 for 6 months). However, annualizing short-term returns is highly discouraged because it mathematically projects a short-term trend over a full year, often resulting in absurdly high numbers.
Compounding occurs when an investment generates earnings, and those earnings are reinvested to generate their own earnings. Over time, this leads to exponential growth.
They measure different things. Absolute return tells you how much money you made in total. CAGR tells you the speed and efficiency of that growth on a yearly basis. You need both for a complete picture.
Nominal value is the absolute dollar amount of your investment before adjusting for the loss of purchasing power caused by inflation.
Real value is the purchasing power of your money after factoring in inflation. If inflation is high, your nominal portfolio might be growing while your real wealth is actually shrinking.
Businesses use CAGR to measure steady growth over time for metrics like revenue, user acquisition, market share, and profit margins.
The Rule of 72 is a mental math shortcut. If you divide 72 by your CAGR, the result is the approximate number of years it will take for your money to double. (e.g., 72 / 10% CAGR = 7.2 years to double).
