About ROI Calculator
ROI Calculator compares the amount invested with the amount returned. It also converts the holding period into an annualized return so investments with different durations are easier to compare.
How to Use
Enter invested and returned amounts, then describe the investment period.
- Enter the original amount invested and final amount returned.
- Choose a numeric length or exact start and end dates.
- Review gain, total ROI, annualized ROI, and duration.
Examples
-
18-month investment
Amount invested: $10,000 Amount returned: $14,000 Investment length: 18 months Investment gain: $4,000.00 ROI: 40.00% Annualized ROI: 25.15%
-
Three-year investment
Amount invested: $25,000 Amount returned: $32,500 Investment length: 3 years Investment gain: $7,500.00 ROI: 30.00% Annualized ROI: 9.14%
Real-World Usage Scenarios
- Cross-Asset Benchmarking - Comparing Stocks and Real Estate - Investors use this to normalize returns across different asset classes. Since a 20% gain in a stock held for 6 months is vastly different from a 20% gain in a property held for 5 years, the annualized ROI metric provides the necessary common ground for capital allocation decisions.
- Marketing Campaign Attribution - Calculating Channel Efficiency - Marketing managers input total ad spend as the invested amount and generated revenue as the returned amount. This helps determine the efficiency of specific seasonal campaigns and justifies future budget increases based on historical performance.
- Capital Expenditure Evaluation - Equipment and Software - Operations leads use the tool to evaluate the return on machinery or enterprise software. By inputting the purchase cost and the documented savings or additional revenue generated over its lifespan, firms can verify if a Capex investment met its internal hurdle rate.
- Venture Capital - Exit Analysis - Venture partners use start and end dates to calculate the precise annualized return of a portfolio company from the initial seed round to a liquidity event, moving beyond simple multiples to understand time-weighted performance.
Frequently Asked Questions
What is the difference between total ROI and annualized ROI?
Total ROI measures the raw percentage gain or loss regardless of time. Annualized ROI shows the geometric mean return per year, allowing you to compare a high-return long-term investment against a quick short-term win.
Should I enter gross or net figures in the calculator?
For the most accurate professional reporting, enter the net investment (including transaction fees/taxes) and net return (after all exit costs). This provides a realistic view of your actual purchasing power gain.
Does this tool account for inflation or currency fluctuations?
No, this calculator measures nominal return. To calculate real return, you must manually adjust your returned amount for inflation or convert both values to a single currency before inputting them.
How is the annualized ROI calculated for periods shorter than one year?
The formula mathematically scales the return to a 12-month period. Note that extremely short durations (e.g., 10 days) can result in highly volatile annualized figures that may not be sustainable over a full year.
