Return on Investment (ROI) is one of the most important financial metrics for evaluating investment performance. Whether you are investing in stocks, real estate, business ventures, cryptocurrency, or any other asset, ROI helps you understand how effectively your money is working for you. Our comprehensive ROI calculator provides not just basic calculations, but advanced metrics like Sharpe ratio, Monte Carlo simulation, and inflation-adjusted returns across 20+ countries.
ROI is a performance measure used to evaluate the efficiency and profitability of an investment. It is expressed as a percentage and shows the return relative to the investment's cost. The basic ROI formula is:
ROI = ((Final Value - Investment Cost) / Investment Cost) × 100
A positive ROI indicates a profitable investment, while a negative ROI shows a loss.
Annualized ROI, also known as Compound Annual Growth Rate (CAGR), is especially useful when comparing investments held for different time periods. The formula accounts for the compounding effect over time:
Annualized ROI = [(1 + Total ROI)^(1/years) - 1] × 100
For example, a 50% total return over 3 years equals approximately 14.47% annualized ROI, not 16.67% (50%/3). This is because the formula accounts for compound growth.
Not all returns are created equal. A 15% return with high volatility may be less desirable than a 10% return with low volatility. The Sharpe Ratio helps measure risk-adjusted performance:
Sharpe Ratio = (Portfolio Return - Risk-Free Rate) / Portfolio Volatility
Inflation erodes purchasing power over time. A 10% nominal return with 3% inflation means your real return is only about 7%. Our calculator automatically adjusts for inflation based on your selected country:
Real Return = ((1 + Nominal Return) / (1 + Inflation Rate) - 1) × 100
Monte Carlo simulation is a powerful tool for understanding investment uncertainty. Instead of showing a single projected outcome, it runs thousands of scenarios with random variations based on expected return and volatility. This gives you:
