ROI Calculator
Calculate return on investment
How the ROI Calculator Works
The ROI (Return on Investment) Calculator measures the profitability of an investment by comparing the net profit to the cost. Enter your initial investment amount, the final value of your investment, any additional costs (fees, taxes, commissions), and optionally the time period to see annualized returns.
ROI is one of the most widely used financial metrics because it is simple to calculate and easy to understand. It applies to virtually any type of investment — stocks, real estate, business ventures, marketing campaigns, or education. By expressing returns as a percentage, ROI allows you to compare investments of different sizes on an equal footing.
Formula
ROI = (Net Profit / Cost of Investment) × 100
Where Net Profit = Final Value − Total Cost of Investment. For example, if you invested $10,000 and the investment is now worth $12,500, your net profit is $2,500 and your ROI is ($2,500 / $10,000) × 100 = 25%.
Understanding ROI, CAGR, and Annualized Returns
While ROI gives you the total return as a single percentage, it does not account for the time it took to achieve that return. A 50% ROI in one year is far more impressive than the same 50% ROI over ten years. This is where annualized ROI and CAGR (Compound Annual Growth Rate) become valuable.
CAGR smooths the return over the investment period and shows a consistent yearly growth rate. The formula is: CAGR = (Final Value / Initial Value)^(1/Years) − 1. Our calculator automatically computes annualized returns when you enter a time period, making it easy to compare investments held for different durations.
When evaluating investment performance, consider context. The S&P 500 has historically returned about 7–10% annually after inflation. A high-yield savings account may offer 3–5%. Real estate typically returns 8–12% per year. Any ROI that consistently beats these benchmarks while matching your risk tolerance is generally considered strong.
