What is the CAGR & ROI Calculator?
Compound Annual Growth Rate (CAGR) measures the smoothed geometric mean return of an investment portfolio across multiple annual holding periods. It neutralizes intermediate market volatility by calculating the steady annualized rate of return mathematically required to expand initial invested capital to final valuation. This provides asset allocators and investment analysts with a normalized performance metric to benchmark asymmetric assets across divergent asset classes and time horizons.
When tracking the performance of mutual funds, stock portfolios, or real estate, looking at simple Return on Investment (ROI) can be highly misleading. If an asset grows by 50%, that sounds incredible. But if it took 10 years to achieve that 50% growth, the investment actually underperformed standard market indices.
This is why Compound Annual Growth Rate (CAGR) is the gold standard for measuring financial performance. CAGR smooths out market volatility and tells you exactly what your investment yielded on an annualized basis, allowing you to accurately compare a swing trading portfolio against a passive index fund.
