ROI (Return on Investment) measures the efficiency of an investment. It tells you how much profit you earned relative to how much capital you risked. A higher ROI means your money is working harder for you.

Measuring Investment Success

Making money is good, but knowing your Rate of Return is essential. A $100 profit is amazing on a $50 investment (200% ROI), but barely noticeable on a $10,000 investment (1% ROI).

Use this calculator to standardize your gains and losses across different asset classes like stocks, real estate, and collectibles.

Simple Return vs. Annualized Return

Note on Time:

This calculator shows Total Return. If you made 20% in 1 year, that is great. If it took 20 years to make 20%, that is poor performance (approx 1% per year).

The Math of Losses

Losses are harder to recover from than you think. If you lose 50% of your portfolio ($100 to $50), you need a 100% gain ($50 to $100) just to break even. This asymmetry is why risk management is critical.
