What is ROI?
Return on Investment (ROI) measures the profitability of an investment as a percentage of the initial cost. It is a key performance indicator used to evaluate the efficiency of an investment or compare the efficiency of different investments. Annualized ROI accounts for the holding period, allowing for fair comparison between investments of different durations.
How to use
Enter your initial investment, final/current value, any additional investments made, fees paid, and the holding period in years. The calculator displays total ROI percentage, annualized ROI, total profit or loss, and helps you evaluate the investment performance.
Frequently Asked Questions
What is Return on Investment (ROI)?
Return on Investment (ROI) is a performance measure used to evaluate the efficiency or profitability of an investment. It calculates the percentage of return on a specific investment relative to its cost.
How do I use this calculator?
Simply enter the 'Amount Invested' (the initial cost) and the 'Amount Returned' (the final value or proceeds). The calculator will instantly compute the ROI percentage and the total profit or loss.
What is the formula used?
The formula used is: ROI = ((Amount Returned - Amount Invested) / Amount Invested) * 100. This gives you the profit as a percentage of the original investment.
Can ROI be negative?
Yes, a negative ROI indicates that you lost money on the investment. This happens when the 'Amount Returned' is less than the 'Amount Invested'.
Does this account for time (e.g., annually)?
No, this calculator provides the total ROI over the entire period of the investment. It does not calculate the annualized return, which would account for how long the money was invested.
What is considered a 'good' ROI?
A 'good' ROI depends heavily on the industry, risk tolerance, and timeframe. Generally, a positive ROI is better than a loss, and investors often look for returns that beat the average market return or inflation.
