ROI Calculator

Calculate return on investment, net profit, and annualized returns.

About This Tool

ROI (Return on Investment) measures how profitable an investment is relative to its cost. A positive ROI means the investment made money; a negative ROI means it lost money. This tool calculates both simple ROI and annualized ROI for multi-year investments.

Annualized ROI uses compound annual growth rate (CAGR) to normalize returns over different time periods, making it easier to compare investments of different durations.

Frequently Asked Questions

What is a good ROI?

It depends on the context. The S&P 500 historically returns about 10% per year. Real estate averages 8-12%. A good ROI should at minimum beat inflation (2-4%) and ideally exceed what you could earn with a low-risk alternative.

What is the difference between ROI and annualized ROI?

Simple ROI shows total return regardless of time. Annualized ROI normalizes it to a yearly rate using CAGR, so you can compare a 2-year investment with a 5-year one on equal footing.

How do I calculate ROI?

ROI = ((Final Value − Initial Investment) ÷ Initial Investment) × 100. For example, invest $10,000 and get back $13,000: ROI = (3,000 ÷ 10,000) × 100 = 30%.
