Calculate the true investment performance. CAGR smooths volatility to show your real growth rate—essential for comparing S&P 500, Bitcoin, real estate, and more.
Why This Matters for Your Finances
Why: Annualized rate of return (CAGR) is the constant yearly rate at which an investment would have grown to reach its ending value from its beginning value. It smooths out volatilit...
How: Enter Initial Investment, Final Value, Time Period to get instant results. Try the preset examples to see how different scenarios affect the outcome, then adjust to match your situation.
- ●CAGR = (Ending Value / Beginning Value)^(1/years) - 1.
- ●Average return is the simple mean of yearly returns.
- ●Convert the period to years first.
- ●Higher volatility often means lower annualized return even with similar average returns.

— S&P Global
Annualized Rate of Return (CAGR) = (Ending Value / Beginning Value)^(1/years) - 1. It smooths out volatility to show the steady rate at which an investment grew. The S&P 500 has returned ~9.8% annualized since 1983. But average return ≠ annualized return: a stock gaining 100% then losing 50% has a 0% average return but 0% annualized (you end at break-even). Warren Buffett's Berkshire Hathaway achieved 19.8% CAGR over 58 years — turning $10K into $360M. Real (inflation-adjusted) annualized returns are typically 3-4% lower than nominal.

📋 Key Takeaways
- Formula = (End/Start)^(1/Years) - 1
- Annualized ≠ average — compounding matters
- A 50% loss requires 100% gain to break even (annualized captures this)
- Always compare annualized returns, not cumulative
📐 CAGR Formula Deep Dive
CAGR converts any holding period into a comparable annual number. A 50% gain over 3 years = 14.5% annualized, not 16.7% (which ignores compounding). This is the only fair way to compare investments across different time periods.
📊 Annualized vs Average Return
A stock that goes +50% then -33% has 0% CAGR but 8.5% simple average return. CAGR accounts for compounding and volatility—it shows the actual wealth-building rate. Simple average can be misleading for volatile investments.
📅 Annualizing Different Periods
For days: years = days/365. For months: years = months/12. A 20% gain in 6 months annualizes to (1.20)^2 - 1 = 44%. The Rule of 72: divide 72 by your CAGR% to estimate years to double. At 7% CAGR, money doubles in ~10.3 years.
⚖️ Annualized Return and Risk
Higher volatility often means lower annualized return. A 30% gain followed by a 20% loss yields ~4% CAGR. Volatility drag reduces compound growth. Diversification can improve risk-adjusted annualized returns.
💰 Real vs Nominal Annualized Return
Nominal return is the raw percentage. Real return subtracts inflation: Real = (1 + CAGR) / (1 + inflation) - 1. If nominal CAGR is 10% and inflation is 3%, real return ≈ 6.8%. Real return shows actual purchasing power growth.
