Frequently Asked Questions
To calculate ROI (Return on Investment), subtract the initial cost of investment from the final value of the investment to find the net profit. Then, divide the net profit by the initial cost and multiply by 100 to express the return as a percentage: ROI (%) = [(Final Value - Initial Cost) / Initial Cost] × 100.
The standard ROI formula is: Net Profit / Initial Investment Cost × 100. For multi-year investments, an annualized ROI formula is best: Annualized ROI = [(Final Value / Initial Value) ^ (1 / Years) - 1] × 100, which accounts for the compound annual growth rate.
A 30% ROI means that your investment generated a net profit equal to 30% of your initial capital. For example, if you invested $10,000 and earned a 30% ROI, your net profit is $3,000, bringing your total return to $13,000.
The CalculatorsDaily ROI calculator is a free digital finance tool that lets you input your total initial investment and final returned amount to instantly calculate your net profit or loss, total ROI percentage, and investment efficiency.
A good ROI percentage depends on the asset class and risk level. Generally, an annual ROI of 7% to 10% is considered good for stock index funds (S&P 500). Real estate investments typically target 8% to 12%, while high-risk private equity or startup investments often target 20% to 30%+ annual returns.
To calculate ROI in Microsoft Excel or Google Sheets, use the formula: =(B2-A2)/A2 where cell A2 contains the Initial Investment Cost and cell B2 contains the Final Returned Amount. Format the cell as a Percentage (%) to display the result.
