How it works

The Return on Investment (ROI) Calculator helps you measure the profitability or efficiency of an investment. It's a key metric for evaluating the performance of an investment relative to its cost.

The Formula

ROI = ((Final Value of Investment - Initial Investment Cost - Additional Costs) / Initial Investment Cost) * 100%

Worked Example

Example: Calculating ROI for a Stock Purchase
You bought shares for $1,000 (Initial Investment). You sold them for $1,250 (Final Value). You also paid $50 in brokerage fees (Additional Costs). Initial Investment = $1,000 Final Value = $1,250 Additional Costs = $50 Gain = $1,250 - $1,000 - $50 = $200 ROI = ($200 / $1,000) * 100% = 20%

Tips, Assumptions & Limitations

Ensure all costs related to the investment (e.g., fees, maintenance) are included in 'Additional Costs' for an accurate ROI.
A positive ROI indicates a profit, while a negative ROI indicates a loss.
ROI is often used to compare the efficiency of different investments.

FAQ

Return on Investment (ROI) is a performance measure used to evaluate the efficiency or profitability of an investment or compare the efficiency of a number of different investments. It directly measures the amount of return on a particular investment, relative to the investment’s cost.

ROI is calculated by subtracting the initial cost of the investment from its final value, then dividing this new number by the initial cost, and finally multiplying by 100 to get a percentage. The formula is: ((Final Value - Initial Cost - Additional Costs) / Initial Cost) * 100%.

ROI is crucial for making informed financial decisions. It helps investors and businesses assess the profitability of past investments, compare different investment opportunities, and allocate resources more effectively to maximize returns.

Yes, ROI can be negative if the final value of an investment, after accounting for all costs, is less than the initial investment. A negative ROI indicates a financial loss.
