FAQ

How to calculate ROI (Return on Investment)?

ROI = (Gain from Investment - Cost of Investment) / Cost of Investment × 100%. For example, investing $100,000 and getting $150,000: ROI = (150K-100K)/100K × 100% = 50%. ROI is one of the most commonly used financial metrics.

What is a good ROI percentage?

A good ROI varies by industry and investment type. Generally, 10-20% annualized ROI is good, above 20% is excellent. However, higher ROI typically comes with higher risk. Compare ROI against the risk-free rate (e.g., treasury yields) for context.

What's the formula for ROI?

Basic ROI: (Net Profit / Investment Cost) × 100%. Annualized ROI: ((1 + ROI)^(1/Years) - 1) × 100%. This tool calculates both total ROI and annualized ROI for comprehensive investment evaluation.

How to calculate annualized ROI?

Annualized ROI = ((End Value/Initial Investment)^(1/Years) - 1) × 100%. It accounts for the investment time period, allowing fair comparison across different time horizons. For example, 50% over 3 years ≈ 14.5% annually.
