Frequently Asked Questions

Everything you need to know about our roi calculator

How do I calculate ROI?

ROI = (Gain - Cost) / Cost × 100%.

ROI = (Final Value - Initial Cost) / Initial Cost × 100. For $1,000 invested growing to $1,300: ($1,300 - $1,000) / $1,000 × 100 = 30% ROI.

What is a good ROI?

Depends on type - stocks average 10%/year, real estate 8-12%.

A "good" ROI depends on the investment type. Stocks historically average 10%/year. Real estate: 8-12%. A savings account at 4% is good for cash. Compare to similar investments.

What is annualized ROI?

ROI adjusted to yearly rate for comparing investments of different durations.

Annualized ROI adjusts total ROI to a yearly rate for fair comparison. A 30% return over 3 years is approximately 9.1% annualized (not 10%, due to compounding).

Why is ROI important?

Quantifies performance as percentage for easy comparison and decision-making.

ROI quantifies investment performance as a percentage, making it easy to compare different investments, justify spending, and make data-driven financial decisions.
