CAGR Calculator

Calculate the Compound Annual Growth Rate of an investment to see its smoothed annualized return.

Formula:
CAGR = (Ending Value / Beginning Value)^(1/n) − 1
Where n = number of years

What is CAGR?

Compound Annual Growth Rate (CAGR) represents the rate at which an investment would have grown if it grew at a steady rate each year. It smooths out the volatility of year-to-year returns into a single number, making it easy to compare different investments.

CAGR vs Average Return

If a stock goes up 50% one year and down 30% the next, the average annual return is 10%. But your actual ending value is lower than starting (1.50 × 0.70 = 1.05, so CAGR ≈ 2.5%). CAGR reflects reality; average return can be misleading.

Typical CAGR Benchmarks

InvestmentHistorical CAGR
S&P 500 (1957-2023)~10.5%
US Bonds (10-yr)~5-6%
Gold (1971-2023)~7.5%
Real Estate (US avg)~3-4%

Limitations

  • Assumes reinvestment of all returns
  • Doesn't show volatility or risk
  • Past CAGR doesn't guarantee future returns
