How to use the ROI Calculator

  1. Enter the amount invested and the total amount returned, or the current value.
  2. Add the holding period in months or years if you want the annualised figure as well.
  3. Read the net profit, the ROI percentage and the annualised return, and copy the breakdown if you need it in a document.

When to use it

ROI is the one figure that lets you compare unlike things: a new espresso machine against a marketing campaign, a training course against a piece of software. Use it before a purchase to set a target, and after to check whether the target was met. For campaigns, treat the spend as the investment and the gross profit on the sales it produced as the return.

Good to know

A simple ROI ignores time, which is why a 20% return over six months and over three years look identical until you annualise them. It also ignores risk and the effort involved, so use it as a comparison tool rather than a verdict.

Frequently Asked Questions

How do I calculate ROI (return on investment)?

Enter your investment amount and return amount into the ROI Calculator — it instantly shows your net profit, ROI percentage, and, if you enter a time period, your annualized ROI.

What is the ROI formula?

ROI = (Net Profit ÷ Investment Cost) × 100. The calculator applies this automatically and also breaks out annualized ROI for multi-year investments.

Can I use this to evaluate a marketing campaign's return, not just a financial investment?

Yes — it works for any scenario where you can express a cost and a resulting return, including marketing campaigns and business investments.
