ROI Calculator
An ROI (Return on Investment) calculator is a high-level financial tool used to evaluate the efficiency and profitability of an investment. Whether you are putting money into the stock market, upgrading business equipment, or launching a marketing campaign, you need to know if the potential gain justifies the cost. ROI is expressed as a percentage, allowing you to compare different investments side-by-side regardless of their size. Our calculator provides a clear picture of your total return, annualized return, and investment "multiple," helping you decide where your capital is most productive.
How to Use ROI Calculator Step by Step
- Enter "Amount Invested" — input the initial cost or capital outlay.
- Enter "Amount Returned" — input the total value of the investment at the end (or current value).
- Add "Investment Period" (Optional) — input the number of years or months to see your "Annualized ROI".
- Include "Additional Costs" (Optional) — input fees, commissions, or maintenance costs.
- Click "Calculate" — the tool will determine your Gain, Total ROI, and Annualized ROI.
- Compare Results — use the ROI percentage to weigh this investment against other opportunities.
ROI Calculator Formula Explained
The total value minus the original investment.
The total capital put at risk.
ROI measures the "Return per Dollar." If you invest $1 and get back $1.50, your profit is $0.50 and your ROI is 50%. While simple ROI is great for a quick check, "Annualized ROI" is more powerful because it accounts for time. A 50% return over 10 years is much less impressive than a 50% return over 1 year. Our calculator uses the "Geometric Mean" formula for annualization to give you a true comparison against bank interest or inflation.
ROI Calculator — Worked Examples
Example 1 — Stock Market Gain
Investing $10,000 in an index fund for 5 years.
Invested: $10k · Returned: $15k · Period: 5 Years

Example 2 — Marketing Campaign
Spending $1,000 on ads that generated $3,500 in new sales.
Cost: $1,000 · Return: $3,500
ROI: 250% · Multiple: 3.5x

Using ROI to justify keeping a losing investment instead of moving capital to a higher ROI opportunity.
