Calculate return on investment, annualized ROI, and net profit. Free online ROI calculator for investors.
Return on Investment (ROI) is one of the most widely used financial metrics for evaluating the profitability of an investment. It measures the gain or loss generated relative to the amount invested, expressed as a percentage. Whether you're evaluating a stock purchase, a real estate deal, a marketing campaign, or a business project, ROI gives you a clear picture of whether the investment was worth it. Our <strong>enterprise digital marketing campaign ROI calculator</strong> enables multi-touch attribution modeling across paid search, social, and email channels. For subscription businesses, the <strong>SaaS customer acquisition cost CAC ROI calculation tool</strong> integrates LTV:CAC ratios and cohort payback analysis directly into performance reporting. Use the <strong>venture capital portfolio compounding interest calculator</strong> for IRR and time-weighted return projections across multiple investment tranches.
The beauty of ROI lies in its simplicity. It provides a quick snapshot of investment performance that can be applied to virtually any scenario where money is spent with the expectation of future returns. However, ROI doesn't account for the time value of money or the holding period, which is why our calculator also provides the annualized ROI for more accurate comparisons between investments of different durations.
You invest $10,000 in a business venture. After 3 years, the investment is worth $15,000. ROI = [(15,000 - 10,000) / 10,000] × 100 = 50%. Annualized ROI = [(15,000/10,000)^(1/3) - 1] × 100 = 14.47%. This means your investment grew at an average rate of 14.47% per year.
