How to use ROI Calculator

Provide the cost and outcome values, and the calculator will show the profit both as dollars earned and as a percentage return.

What this calculator is for

This calculator is for quick investment and project comparisons when a simple profit-to-cost ratio is enough. It does not account for time on its own, which is why ROI is often best paired with annualized measures when timelines differ.

Tips

Two projects can share the same ROI but have very different time horizons, so do not use ROI alone when timing matters.
If fees or carrying costs were part of the investment, include them in total cost before trusting the reported return.
