🎯 ROI Calculator
How It Works
Calculate return on investment as a percentage and profit or loss. Use it to understand the key payment, cost, return, or cash-flow result before making a decision. Use ROI Calculator to explore how the main financial inputs change the payment, cost, return, or cash-flow result before making a decision.
The result is most useful when the inputs match the definitions used by this calculator. For this tool, the underlying method is: ROI = ((Final Value − Initial Investment) / Initial Investment) × 100. Compare the output with the worked example, then change one meaningful input at a time to see how the result responds.
What Is ROI?
ROI (return on investment) is a percentage measure of how much an investment gained or lost relative to its original cost. It helps compare the size of a return with the amount of capital committed.
How to interpret the result: Compare the output with the worked example and with another scenario using the same definitions. For this calculator, the key relationship is ROI = ((Final Value − Initial Investment) / Initial Investment) × 100.
How to Calculate ROI
The page uses the method shown in the Formula section: ROI = ((Final Value − Initial Investment) / Initial Investment) × 100. Keep the inputs in matching units, then change one meaningful input at a time when testing scenarios.
Important limitation: ROI does not by itself account for the time an investment was held, taxes, financing costs, risk, or cash-flow timing. Review the roi inputs and units before relying on the result.
ROI formula and a simple example
ROI is commonly calculated as (gain or loss ÷ original investment) × 100. For example, an investment that rises from 10,000 to 12,000 has a 20% simple ROI before considering additional costs.
ROI vs profit
Profit is the money gained or lost; ROI expresses that gain or loss relative to the original amount invested. A larger profit does not automatically mean a higher ROI if the amount invested was also much larger.
Why holding period matters
Basic ROI does not by itself annualize a return. Two investments can have the same ROI but very different time periods, risk, fees, taxes, and cash-flow patterns.
What to check before using the result
Include relevant acquisition or transaction costs when they belong to the investment scenario, and do not treat a simple ROI percentage as a complete measure of investment performance.
When to Use This Calculator
Use ROI Calculator to explore how the main financial inputs change the payment, cost, return, or cash-flow result before making a decision.
Practical tip: For this ROI Calculator, change one financial assumption at a time—such as the rate, amount, contribution, fee, or tenure shown in the inputs—so you can see which factor drives the result.
Formula
ROI = ((Final Value − Initial Investment) / Initial Investment) × 100
Example
Invest $5,000 and receive $6,000: ROI = 20%. Use the calculator to test a second scenario and see how the result changes when one important assumption is adjusted.
