Máy tính ROI

Return on investment (ROI) is one of the most important metrics for evaluating the performance of any investment. Whether you're tracking stock gains, real estate returns, or business investments, understanding your ROI percentage helps you make smarter financial decisions. Our free ROI calculator makes it simple to calculate your returns instantly without registration or fees.

What is ROI and Why Does It Matter?

ROI (Return on Investment) is a percentage that shows how much profit or loss you've made relative to your initial investment. If you invested $1,000 and it's now worth $1,250, your ROI is 25%. This metric allows you to compare performance across different investments and timeframes on an equal basis.

How to Use the Free ROI Calculator

Calculating your ROI takes just three simple steps:

Step 1: Enter Your Initial Investment Amount - Click the input field labeled "Initial Investment" and type the exact amount of money you originally invested. For example, if you bought $5,000 worth of stock, enter 5000.

Step 2: Enter Your Current Investment Value - In the "Final Value" field, type what your investment is worth today. If that $5,000 stock position is now worth $6,250, enter 6250 in this field.

Step 3: Get Your ROI Percentage - The calculator instantly displays your ROI percentage. In this example, you'd see 25%, meaning a 25% return on your investment.

ROI Calculation Formula Explained

Our calculator uses the standard ROI formula: (Final Value - Initial Investment) ÷ Initial Investment × 100 = ROI Percentage

Using the example above: ($6,250 - $5,000) ÷ $5,000 × 100 = 25%

A positive ROI percentage indicates a gain, while a negative percentage shows a loss. For instance, if your investment dropped to $4,000, the ROI would be -20%, representing a 20% loss.

Real-World ROI Calculator Examples

Real Estate Example: You purchased a rental property for $200,000. After improvements and appreciation, it's worth $280,000. Your ROI is 40%.

Business Investment Example: You invested $10,000 in a startup. Your stake is now valued at $8,500 after a market downturn. Your ROI is -15%.

Pro Tips for Using the ROI Calculator

Track Multiple Investments - Use the calculator separately for each investment to compare which performs best. Paste results into a spreadsheet to track your portfolio's overall performance.

Include All Costs - When calculating initial investment, factor in purchase fees, commissions, or closing costs for a more accurate ROI picture.

Account for Dividends and Interest - Add any dividend payments or interest earned to your final value for a complete ROI calculation.

Calculate Annualized Returns - For investments held over multiple years, divide your ROI percentage by the number of years to get approximate annual returns.

Difference Between ROI and Other Investment Metrics

ROI shows total percentage return but doesn't account for time. Annualized ROI divides returns by years held. ROIC (Return on Invested Capital) includes borrowed money. Net ROI subtracts fees and taxes. Our calculator shows gross ROI percentage, the most straightforward investment metric.
