About the ROI Calculator
Calculate return on investment as a percentage. It is a planning aid for comparing scenarios; it is not financial, tax, lending, or investment advice.
The calculation uses investment cost, and final value.
How to use it
- Review the starting values for investment cost, final value and replace them with your own.
- Choose any available units or assumptions, then select “Calculate.”
- Read the labeled result, compare another scenario if needed, and copy the output for your notes.
Practical example
Start with a known input

What to know about the result
- Results are estimates based only on the supplied values. Rounding, fees, local rules, and real-world conditions may change the final outcome.
