ROI Calculator — Measure Your Investment Performance — USA 2026
Free ROI calculator to calculate return on investment for any business project or financial investment. Compare ROI across different opportunities.
Return on Investment is the universal metric for measuring the profitability of any investment whether it is a business project real estate purchase stock market investment marketing campaign or education. ROI tells you how much profit you earned for every dollar or rupee invested. A 50% ROI means you earned Rs 50 for every Rs 100 invested. Understanding ROI helps you allocate your capital to the highest-returning opportunities.
How is ROI calculated?
ROI = (Net Profit / Cost of Investment) x 100. For example if you invested $10000 in stocks and sold them for $13000 your ROI = (13000 - 10000) / 10000 x 100 = 30%. This simple formula works for any investment but does not account for time — a 30% return in 1 year is much better than 30% over 5 years. Use annualized ROI for time-adjusted comparisons.

Understanding Your Investment Returns
This calculator projects your returns using compound interest, where your earnings generate their own earnings over time. The power of compounding means that even small regular investments can grow into substantial wealth over long periods. For example, investing just Rs 5,000 per month at 12% expected returns for 25 years can grow to over Rs 1 crore — of which only Rs 15 lakh is your own money and Rs 85 lakh is compounding returns. The key factors that determine your final corpus are: the amount invested, the rate of return, the duration of investment, and the frequency of compounding.
Important Considerations
Past returns do not guarantee future performance, especially for market-linked instruments like mutual funds and equities. The returns shown are estimates based on the rate you enter. Equity investments carry market risk but have historically delivered 12-15% CAGR over 15+ year periods in India. Fixed income options like PPF (7.1%) and FD (6-7.5%) offer lower but more predictable returns. Diversifying across asset classes — equity, debt, gold, and real estate — reduces overall portfolio risk while optimizing returns for your risk tolerance.

Frequently Asked Questions
How is ROI calculated?
ROI = (Net Profit / Cost of Investment) x 100. For example if you invested $10000 in stocks and sold them for $13000 your ROI = (13000 - 10000) / 10000 x 100 = 30%. This simple formula works for any investment but does not account for time — a 30% return in 1 year is much better than 30% over 5 years. Use annualized ROI for time-adjusted comparisons.
What is a good ROI?
A good ROI depends on the context and risk. For stock market investments 7-10% annually is considered good (matching the S&P 500 average). For real estate 8-12% including rental income and appreciation is good. For business investments 15-30% ROI is typically expected to justify the effort and risk. Any ROI above the risk-free rate (currently 4-5% for US Treasury bonds) adds value.
How does ROI differ from CAGR?
ROI gives you the total percentage return without considering time while CAGR (Compound Annual Growth Rate) gives you the annualized return accounting for compounding. A 100% ROI over 7 years = 10.4% CAGR. Always use CAGR when comparing investments held for different time periods. ROI is better for quick assessment while CAGR is better for detailed comparison.
What is compound interest and why does it matter?
Compound interest means you earn interest on your interest, not just your principal. Over long periods, this creates exponential growth — even small regular investments can grow into substantial wealth over 15-25 years.
Should I invest regularly or as a lump sum?
Regular investing (dollar-cost averaging) smooths out market volatility by buying at various price points. Lump sum investing works better if markets are undervalued. For most people, regular monthly investing is simpler and more disciplined.
How much should I invest monthly to reach my goal?
The amount depends on your target, timeline, and expected returns. Use this calculator to model different scenarios. The key factors are starting early, investing consistently, and reinvesting returns.
Are investment returns taxable?
Tax treatment varies by investment type and country. Capital gains, dividends, and interest income may be taxed differently. Consult a tax professional for advice specific to your situation and jurisdiction.
