ROI Calculator

Calculate Your Return on Investment (ROI)

Return on Investment (ROI) is one of the most important metrics for evaluating the profitability of an investment, business decision, or project. It tells you how much you gained (or lost) relative to what you invested.

Understanding ROI

The formula is simple: ROI = (Final Value - Initial Investment) / Initial Investment × 100%

What ROI Tells You

• Positive ROI: You made money on your investment
• Negative ROI: You lost money
• Higher percentage: Better return relative to your investment

Example: Invest $10,000, sell for $12,500

• Profit: $2,500
• ROI: 25%

This means you earned 25 cents for every dollar invested.

Common Uses for ROI

Interpreting Your Results

10% or higher: Generally considered good for most investments

20%+ annually: Excellent returns; Warren Buffett averages ~20%

Negative: Loss; reassess the investment or strategy

100%+: Exceptional; you doubled your money or more!

ROI Limitations

Keep in mind:

• Time matters: 10% ROI in 1 year is better than 10% over 5 years
• Risk isn't considered: Higher returns often mean higher risk
• Doesn't show timing: When you earned the return matters for compounding
• Excludes other factors: Taxes, fees, and opportunity costs aren't included

Making Better Investment Decisions

1. Compare ROIs across different opportunities
2. Factor in time by calculating annualized returns
3. Consider risk alongside returns
4. Include all costs (fees, maintenance, taxes)
5. Look at trends over multiple periods
