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 โˆ’ Initial Investment) รท Initial Investment) ร— 100. For example, invest $10,000 and get back $13,000: ROI = (3,000 รท 10,000) ร— 100 = 30%.

How to Calculate ROI

Enter your initial investment amount and the final value (or profit). The calculator shows your total return, ROI percentage, net profit, and annualized return (CAGR) if you specify the investment duration. CAGR lets you compare investments of different lengths on equal footing.

Understanding ROI and CAGR

ROI (Return on Investment) measures total return as a percentage of cost. A $10,000 investment that grows to $15,000 has a 50% ROI. Simple, but it ignores time. An investment that returns 50% in one year is very different from one that takes ten years.

CAGR (Compound Annual Growth Rate) solves this by expressing the return as an equivalent annual rate. It answers the question: at what annual rate would my investment have grown to reach this final value? This makes comparing stocks, real estate, business investments, and savings accounts straightforward.
