ROI Calculator

What is ROI?

ROI (Return on Investment) is a performance measure used to evaluate the efficiency or profitability of an investment. It compares the gain or loss from an investment relative to its cost. ROI is one of the most widely used financial metrics because it's simple to calculate and easy to understand.

Investors use ROI to compare the profitability of different investments, assess past performance, and make informed decisions about where to allocate capital. A positive ROI indicates a profitable investment, while a negative ROI shows a loss. For analyzing growth rates over time, see our CAGR Calculator which shows compound annual growth rates.

How to Use This Calculator

Using the ROI calculator is straightforward. Enter your initial investment amount, the final or current value of your investment, any additional costs (fees, taxes, etc.), and the investment duration in years. The calculator instantly shows your total ROI, annualized ROI, and profit or loss.

The annualized ROI is particularly useful for comparing investments held for different time periods, as it shows the average annual return rate. This allows you to make apples-to-apples comparisons between different investment opportunities.

Formula Explained

The ROI formula is:

Where:

• Final Value = Current or ending value of the investment
• Initial Investment = Original amount invested
• Additional Costs = Fees, taxes, and other expenses

For annualized ROI, the formula accounts for the time period: Annualized ROI = ((1 + ROI)^(1/Years) - 1) × 100. This gives you the compound annual growth rate (CAGR) of your investment.

Tips for Best Results

• Include all costs: For accurate ROI, include transaction fees, management fees, taxes, and any other expenses associated with the investment.
• Use annualized ROI for comparisons: When comparing investments with different time periods, use annualized ROI to get an accurate comparison.
• Consider risk: Higher ROI often comes with higher risk. Don't make decisions based solely on ROI without considering risk tolerance.
• Compare to benchmarks: Compare your ROI to relevant benchmarks like the S&P 500 for stocks or market averages for your investment type.
