What is the CAGR Calculator?
CAGR — Compound Annual Growth Rate — is the single number that answers “how fast did this investment actually grow?” It converts a messy multi-year journey with crashes and rallies into one smooth annual rate, making investments comparable on a level field.
This calculator is for investors evaluating a mutual fund against its benchmark, comparing property against gold, or auditing their own portfolio’s performance. It is the language of honest comparison: absolute returns (“I doubled my money!”) are meaningless without the time dimension that CAGR supplies.
CAGR’s limitation is that it hides the journey — two investments with identical CAGRs can have wildly different volatility. Pair CAGR with a look at maximum drawdown before drawing conclusions about quality. For SIPs and portfolios with multiple cash flows, use XIRR instead, since CAGR assumes a single lumpsum.
The CAGR formula
CAGR = (End ÷ Begin)^(1 ÷ Years) − 1
| Symbol | Meaning |
|---|---|
| End | Final value of the investment |
| Begin | Initial value |
| Years | Holding period in years (decimals allowed) |
Worked example
₹1,00,000 becoming ₹3,00,000 in 8 years: CAGR = (3)^(1/8) − 1 ≈ 14.7%. The absolute return is 200%, but annualised it is 14.7% — the number to compare against Nifty’s ~12% or an FD’s ~7%.
| Journey | Absolute return | CAGR |
|---|---|---|
| 2× in 5 years | 100% | 14.9% |
| 2× in 10 years | 100% | 7.2% |
| 3× in 8 years | 200% | 14.7% |
| 3× in 15 years | 200% | 7.6% |
Benefits of the CAGR Calculator
One comparable number across all assets
CAGR lets you compare a 5-year FD, a 10-year fund, and a 15-year property on the same annualised basis.
Simple, universal, benchmark-friendly
Every fund house, index, and analyst quotes CAGR; knowing yours lets you benchmark against anything.
Removes marketing spin from return claims
“200% returns” sounds huge until CAGR reveals it as 7.6% over 15 years — the honest number.
Works for any two-point measurement
Any asset with a start value, end value, and duration can be annualised — stocks, funds, property, gold.
Easy to compute and verify
A simple formula anyone can calculate on a phone calculator, with no software or data feed required.
Limitations to keep in mind
Hides volatility and drawdowns completely
A 14% CAGR with 50% drawdowns is a very different experience from 14% with 15% drawdowns — CAGR cannot tell them apart.
Invalid for multiple cash flows (use XIRR)
CAGR assumes one investment and one redemption; SIPs, partial withdrawals, and dividends need XIRR instead.
Sensitive to chosen start/end points
Measuring from a crash bottom to a bubble top flatters any asset — use standard, comparable periods.
Says nothing about future returns
A 15% historical CAGR does not predict 15% going forward; past performance does not guarantee future results.
Misleading for periods under one year
Annualising short periods exaggerates wildly — a 5% month “annualises” to 80%, which is meaningless.
Common mistakes to avoid
Comparing absolute returns across different periods
“Doubled” means everything at 5 years and almost nothing at 20 — always annualise with CAGR first.
Using CAGR for SIP investments
CAGR assumes one lumpsum; for staggered cash flows use XIRR instead.
Cherry-picking start and end dates
Measuring from a crash bottom to a bubble top flatters any asset — use standard periods.
Ignoring what CAGR hides
A 14% CAGR with 50% drawdowns is a very different experience from 14% with 15% drawdowns.
Annualising periods under a year
A 5% month “annualises” to 80% — avoid annualising anything under one year.
Expert tips for better results
Use XIRR for SIPs and portfolios
Any investment with multiple cash flows needs XIRR, not CAGR — most brokers and apps compute it automatically.
Judge CAGR over full market cycles
A 7–10 year window captures at least one bull and bear phase; 1–3 year CAGRs are noise.
Pair CAGR with maximum drawdown
Two funds with the same CAGR can differ hugely in risk; drawdown shows the worst dip you would have endured.
Benchmark against a relevant index
Compare your fund’s CAGR to its category benchmark, not the Nifty — a small-cap fund should beat the small-cap index.
Never annualise sub-year periods
Short-period annualisation is mathematically valid but practically meaningless; quote absolute returns for under one year.
When to use this calculator
- Comparing a fund against its benchmark
- Annualising property or gold appreciation
- Auditing your own portfolio’s performance
- Cutting through “multi-bagger” marketing claims
