📈 CAGR / APY Calculator

The CAGR (Compound Annual Growth Rate) calculator measures your investment's annualized return — the gold standard for evaluating investment performance. Input parameters: • Initial investment amount • Final value • Number of years Formula: CAGR = (Final Value / Initial Investment)^(1/Years) - 1 Output: • CAGR as a percentage • Total return rate • Absolute gain amount CAGR vs simple average return: CAGR accounts for compounding and better reflects true annualized returns. Example: +50% then -50% gives a simple average of 0%, but the CAGR is -13.4%. Common use cases: evaluating fund/stock long-term performance, comparing different investments, portfolio analysis.
