ROI Calculator

Calculate Return on Investment (ROI) to measure the profitability of an investment or expense.

Our free ROI Calculator lets you calculate Return on Investment (ROI) to measure the profitability of an investment or expense. It is built for homebuyers, borrowers, investors, and anyone managing personal or business finances who need fast, reliable results without installing software or creating an account.

ROI Calculator runs entirely in your browser on CalculatorsPlus — enter your values, get instant results, and copy or share your output in one click. Your data never leaves your device; we do not store inputs on any server.

Financial planning starts with understanding the numbers behind roi calculator scenarios. Adjust inputs to compare options side by side — for example, how a 0.5% rate change or an extra monthly payment affects your total cost over time.

Results update in real time as you change inputs, so you can explore "what if" scenarios — adjust one variable at a time to see how it affects the outcome before committing to a purchase, plan, or decision.

This page includes step-by-step instructions, frequently asked questions, and practical tips below the calculator. Bookmark it for repeat use — many finance tasks come up weekly during projects, studies, or financial planning.

Frequently Asked Questions

How is ROI calculated?
ROI = (Net Profit / Cost of Investment) × 100. For example, if you invest $1,000 and gain $1,200, ROI = (200/1000) × 100 = 20%.
What is a good ROI?
A good ROI depends on the context. Stock market average is ~10% annually. Real estate averages 8–12%. Any ROI above the risk-free rate (treasury bonds) may be considered worthwhile.
Does ROI account for time?
Basic ROI does not account for time. For time-adjusted returns, use annualized ROI or IRR (Internal Rate of Return) to compare investments over different periods.
What is the difference between ROI and ROE?
ROI measures return relative to total investment cost. ROE (Return on Equity) measures return relative to shareholder equity — it is specific to businesses.
