Still struggling to calculate your return on investment? By entering your initial investment amount, return value, and investment period, this tool automatically calculates your investment profit/loss, actual investment days, Return on Investment (ROI), and Annualized Return on Investment (AROI). ROI is a core metric for measuring investment efficiency, defined as the percentage ratio of (Return Value - Initial Investment) to the Initial Investment.
Is the annualized return reliable if the investment period is less than a year?
The Annualized Return (AROI) is calculated using the formula ROI × (365 / actual days). This allows even short-term investments to be standardized for comparison. For example, a 90-day investment period will be converted using a multiplier of 365/90 ≈ 4.06.
Does the input amount support currency symbols or thousand separators?
Only pure numeric inputs are supported, such as "10000". Entering "$10,000" or "10,000 USD" will result in a calculation error.
The initial investment must be > 0; the end date cannot be earlier than the start date. Results are for reference only. Actual investments should consider comprehensive factors such as inflation and taxes. We recommend clearing sensitive data after saving it locally.
We recommend combining this with IRR (Internal Rate of Return) for a multi-dimensional evaluation. Typical scenario: An initial investment of $10,000 returning $12,000 after 1 year results in an ROI of 20% and an AROI of 20%. If the risk-free rate during the same period is 3%, the excess return reaches 17%.
