ROI Calculator

Calculate the Return on Investment (ROI) and annualized return for any investment.

How to Use ROI to Make Better Financial Decisions

Return on Investment (ROI) is the single most universal metric in finance. Whether you're evaluating a stock, a marketing campaign, a rental property, or a business purchase, ROI tells you one thing clearly: for every dollar you put in, how many dollars do you get back?

ROI Formula

ROI = (Net Profit ÷ Cost of Investment) × 100. If you invest $10,000 and receive $13,000 back, your net profit is $3,000 and your ROI is 30%. Simple — but powerful when used consistently to compare opportunities.

Annualized ROI — The Fairer Comparison

A 50% ROI sounds great — but was it over 1 year or 10 years? Annualized ROI accounts for time, letting you compare a 2-year investment returning 30% against a 5-year investment returning 80% on equal footing. This calculator shows both figures so you can evaluate investments correctly.

What Counts as a Good ROI?

Stock market — ~10% annual ROI (historical S&P 500 average)
Real estate — 8–12% annual ROI including appreciation and rental income
Business investment — 15–30%+ is typically targeted
Marketing — $5 return per $1 spent (500% ROI) is a common benchmark
High-yield savings — 4–5% annual ROI (low risk)

Frequently Asked Questions

What is the difference between ROI and ROE?

ROI (Return on Investment) measures profit relative to total cost. ROE (Return on Equity) is a corporate metric measuring profit relative to shareholder equity. For personal investing decisions, ROI is the more versatile and commonly used metric.

Does ROI account for inflation?

Standard ROI does not account for inflation. To find real ROI, subtract the inflation rate from your nominal return. If your investment returned 8% and inflation was 3%, your real ROI is approximately 5%. For long-term investments, always consider real (inflation-adjusted) returns.

What is a negative ROI?

A negative ROI means you lost money on the investment — you got back less than you put in. While negative ROI is obviously bad financially, sometimes investments with expected negative financial ROI make sense for strategic, brand, or long-term reasons (e.g., early-stage marketing).
