CAGR Calculator: What Is CAGR and How to Measure Your Investment Growth Rate
CAGR is the most accurate way to compare investment returns across different time periods. Learn what CAGR means, how to calculate it, and how to use Moneykar's CAGR calculator.
When someone says their investment "returned 80% in 5 years," that sounds impressive — but is it? The answer depends entirely on when the return was earned. CAGR (Compound Annual Growth Rate) is the metric that standardises investment returns across different time horizons, making honest comparison possible. Moneykar's CAGR calculator does this in seconds.
What is CAGR?
CAGR represents the constant annual rate at which an investment would have grown to reach its ending value from its starting value, assuming profits were reinvested throughout. It answers the question: "If this investment grew at a steady pace each year, what would that pace be?"
It's the most widely used metric in finance for comparing mutual funds, stocks, real estate, and any investment held over multiple years.
CAGR formula and how to calculate it
CAGR = (Ending Value / Beginning Value)^(1/n) – 1
Where n = number of years.
Example: You invested ₹2 lakh in a mutual fund in 2017. In 2025 (8 years later), it is worth ₹5 lakh.
CAGR = (5,00,000 / 2,00,000)^(1/8) – 1 = (2.5)^0.125 – 1 = 0.1213 = 12.1% per year
CAGR vs Absolute Return: why the difference matters
| Investment | Start | End | Absolute Return | Duration | CAGR |
|---|---|---|---|---|---|
| Fund A | ₹1L | ₹2.5L | 150% | 8 years | 12.1% |
| Fund B | ₹1L | ₹2.5L | 150% | 5 years | 20.1% |
| FD | ₹1L | ₹1.7L | 70% | 8 years | 6.9% |
Funds A and B have the identical absolute return — but Fund B is far superior because it delivered that return in 5 years instead of 8. CAGR reveals this; absolute return hides it.
Benchmark CAGR figures for India (reference)
- Nifty 50: ~12–14% CAGR over 20 years (price return, pre-tax)
- Gold: ~10–12% CAGR in INR over 20 years
- FD (large banks): ~6.5–8% CAGR
- PPF: ~7–8% CAGR (fully tax-free)
- Indian real estate: ~5–8% CAGR (varies widely by location)
These are historical references, not return guarantees. Past CAGR does not predict future CAGR.
When CAGR can mislead: the volatility problem
CAGR assumes smooth, steady growth. In reality, markets are volatile. An investment that fell 50% and then doubled shows a 0% CAGR — but an investor who sold during the fall locked in real losses. For volatile investments, use CAGR alongside Standard Deviation (how bumpy the journey was) to get a complete picture.
