CAGR Calculator
Calculate the compound annual growth rate of your investment.
What Is the CAGR Calculator?
CAGR (Compound Annual Growth Rate) measures the average annual growth rate of an investment over a specific period, assuming any gains are reinvested every year. It's one of the most widely used metrics for evaluating investment performance because it condenses a messy, real-world growth path — good years, bad years, flat years — into a single, comparable annual percentage.
The idea rests on the same compounding principle used throughout investing: money doesn't just grow, it grows on its own growth. A steady 12% annual rate over 10 years produces a dramatically larger outcome than 10 years at 8%, precisely because each year's gains become part of the base for the next year's gains. This is the same underlying math used in the Future Value Calculator and the Compound Interest Calculator — CAGR essentially works backward from a known start and end value to find the constant rate that connects them.
Because it strips out timing and volatility, CAGR is the standard way analysts, fund fact sheets, and investors compare returns across stocks, mutual funds, businesses, or even entire economies — even though no real investment actually grows at a perfectly constant rate every single year.
CAGR Calculator Formula
CAGR = ((Final Value / Initial Value) ^ (1 / Years) − 1) × 100
How Is the CAGR Calculator Calculated?
CAGR finds the single constant annual growth rate that would take your initial value to your final value over the given number of years, smoothing out any year-to-year fluctuations into one steady, comparable figure — even though real investments rarely grow at a perfectly constant rate every year. Mathematically, it's the geometric mean of the yearly growth factors, not a simple average, which is exactly why it correctly accounts for compounding instead of overstating returns the way a plain arithmetic average would.
This distinction matters more than it seems: an investment that gains 50% one year and loses 50% the next has an average return of 0% by simple arithmetic, but its actual CAGR is negative — a $50,000 investment that loses 50% falls to $25,000, and a 50% gain on that smaller base only brings it back to $37,500, still below where it started. CAGR reflects this real, compounded outcome rather than the misleading arithmetic average.
CAGR Calculator Example
An investment growing from $200,000 to $500,000 over 5 years has a CAGR of about 20.1% per year.
A slower-growing investment moving from $100,000 to $250,000 over 7 years has a CAGR of about 14.0% per year — a lower annual rate than the first example, even though both investments grew 2.5x in total, simply because it took longer to get there.
CAGR can also be negative: an investment that fell from $50,000 to $40,000 over 3 years has a CAGR of about -7.2% per year, reflecting a genuine average annual decline.

- Works for any asset — stocks, mutual funds, real estate, or even business revenue.
- Turns your result into a shareable branded image card for WhatsApp or social apps in one tap, instead of typing numbers out by hand.
Common CAGR Calculator Scenarios
Scenario 1
Comparing the historical performance of a stock, fund, or portfolio.
Scenario 2
Evaluating a business's revenue or profit growth over several years.
Scenario 3
Benchmarking an investment's actual performance against a target rate.
Scenario 4
Working backward from a financial goal to see what growth rate would be required.
Scenario 5
Comparing two funds with different starting and ending dates on equal footing.
Scenario 6
Checking whether a "doubled my money" claim is actually a strong return once the time period is factored in.
Understanding Your Result
CAGR represents the smoothed, constant annual growth rate that connects your starting and ending values. It does not reflect the actual volatility along the way — a volatile investment and a steady one can have the same CAGR despite very different year-to-year experiences.
A higher CAGR generally means stronger annualized performance, but it should always be read alongside the time period and the asset's risk profile. A 20% CAGR over 2 years is a very different — and far less proven — result than a 20% CAGR sustained over 15 years, even though the calculator reports both the same way.
Tips
- Use CAGR to compare investments consistently, since it neutralizes the effect of when gains or losses happened.
- Remember CAGR smooths out volatility — two investments with identical CAGR can have very different risk profiles.
- A CAGR above roughly 12% is often considered strong for long-term equity investments, though this varies by market conditions.
- Use at least a 3-5 year window where possible — CAGR over very short periods can be skewed by a single unusually good or bad year.
- Pair CAGR with the actual rupee gain (final value minus initial value) so a high percentage on a small base doesn't look more impressive than it really is.
Common Mistakes
- Assuming CAGR reflects the actual year-by-year return path, when it's only a smoothed average.
- Comparing CAGR figures calculated over different time periods without noting the difference.
- Using CAGR alone without considering volatility or risk when comparing investments.
- Calculating CAGR over a very short window (under 2-3 years) and treating it as a reliable long-term rate.
- Mixing up CAGR with total return percentage — a 150% total gain over 10 years is roughly a 9.6% CAGR, not 15%.
Frequently Asked Questions
What is a good CAGR?
Generally, a CAGR above 12% is considered strong for equity investments over the long term, though this varies by asset class and market conditions. For debt instruments or fixed-income products, a CAGR in the high single digits is often considered solid instead.
Is CAGR the same as annual return?
No. CAGR smooths out yearly fluctuations and shows a single, consistent annual growth rate rather than the actual year-by-year returns.
Can CAGR be used for mutual funds?
Yes. CAGR is commonly used to compare mutual fund, stock, and portfolio performance over multi-year periods.
How is CAGR different from the SIP Return calculator's return percentage?
CAGR gives an annualized rate, while the SIP Return calculator's percentage shows total cumulative profit relative to total invested — useful for different comparison purposes.
Can CAGR be negative?
Yes, if the final value is lower than the initial value, CAGR will be negative, reflecting an average annual decline. This can happen even if some individual years within the period were positive, since CAGR only looks at the start and end points.
Does CAGR account for volatility along the way?
No — CAGR smooths returns into a single average annual rate, so it doesn't show how bumpy the ride was between the start and end values, even if two investments with the same CAGR had very different year-to-year swings.
Can I use CAGR to compare a stock and a mutual fund?
Yes — since CAGR normalizes any investment's growth into an annualized percentage, it's a fair way to compare returns across different asset types over the same time period.
What time period is CAGR most useful for?
CAGR is most meaningful over longer periods (3+ years) — for very short periods, a single good or bad month can distort the annualized figure.
Does CAGR account for additional contributions during the period?
No — CAGR assumes a single initial value grows to a single final value with no additional deposits or withdrawals in between; use a SIP or Investment Growth calculator if you're adding money regularly.
Can I share my CAGR result as an image?
Yes — tap Share and, on supported devices, your CAGR is shared as a branded image card, not just a text link.
How do I calculate CAGR if I only know the total percentage return?
Convert the total return into a final-value multiple first — a 150% total return means the final value is 2.5x the initial value — then apply the CAGR formula with that multiple and the number of years. A large total return spread over many years often corresponds to a much smaller annual CAGR than it first appears.
Can CAGR be used for periods shorter than a year?
It can be adapted using a fractional year value, but CAGR is most meaningful — and most commonly used — for periods of a year or longer.
Does this calculator adjust CAGR for inflation?
No — this shows the nominal CAGR based on the raw values you enter. Use the Inflation calculator's rate alongside it to estimate a real, inflation-adjusted growth rate if you need purchasing-power comparisons.
What CAGR would double my money in a given number of years?
As a quick approximation, dividing 72 by the number of years gives roughly the CAGR needed to double an investment (the Rule of 72) — for example, doubling in 6 years corresponds to a CAGR of roughly 12%.
