ROI Calculator
Measure return on investment as a percentage gain or loss.
About This Calculator
ROI stands for return on investment. It measures how much profit or loss you made compared with the original amount you spent. The result is shown as a percentage, which makes it easier to compare different opportunities.
Formula: ROI = (Final Value - Initial Investment) / Initial Investment x 100. A positive value means the investment grew, while a negative value means the final value is below your starting cost.
Example: If you invest 5,000 and your final value becomes 6,500, the profit is 1,500 and the ROI is 30%.
ROI is useful because it is simple, but it does not show how long the investment took, what taxes or fees were involved, or how much risk you accepted. It is best used as a quick comparison tool, not as the only decision factor.
How To Use ROI In Real Decisions
ROI can be used for stocks, small business spending, marketing campaigns, equipment purchases, rental upgrades, and many other situations where you want to compare cost against return.
A higher ROI usually points to a more efficient use of money, but the context still matters. Two investments can have the same ROI while taking very different amounts of time to get there.
There is no normal ROI that fits every project. In practice, a good ROI depends on your industry, risk level, time frame, financing costs, and alternative options available to you.
