Calculate return on investment including total ROI percentage and annualized return. Compare investment performance across different time horizons.
Return on Investment (ROI) is the universal metric for evaluating any financial decision, from stock purchases to real estate to business investments. This calculator computes both total ROI and annualized return, allowing you to compare investments with different time horizons on an apples-to-apples basis.
The ROI Calculator measures the profitability of an investment by comparing the gain or loss relative to its initial cost. Total ROI is calculated as (Final Value - Initial Investment) / Initial Investment, expressed as a percentage. The annualized return converts this total return into an equivalent yearly rate using the geometric mean formula, which accounts for compounding effects over multiple years. This methodology allows investors to compare investments held for different time periods on an apples-to-apples basis. A portfolio that returned 50% over 3 years has a lower annualized return than one that returned 40% over 2 years, even though the total percentage is higher. The calculator is essential for evaluating investment decisions, comparing assets with different holding periods, and setting performance benchmarks. It does not account for dividends received, taxes, or inflation, which can significantly affect actual returns. For a comprehensive analysis, consider using the annualized total return which includes dividend income.
Result: Total ROI: 150%. Annualized Return: 20.1%. Total Gain: $15,000.
