Business ROI Calculator
Annualised, and with a present value beside it.
Total ROI
10%
3.2% annualised
Total ROI over 3.0 years is 10%, which annualises to 3.2%. Quoting the total without the period is how modest investments get presented as exceptional ones.
How the Business ROI Calculator works
Quoting total ROI without the period is how modest investments get presented as exceptional ones. A 60% return over three years annualises to under 17%, which is a different conversation entirely.

Frequently asked questions
How is ROI calculated?
Net gain divided by investment. Annualising it — taking the nth root over n years — is what makes returns comparable across different time periods.
What is net present value?
Future returns discounted back to today at your cost of capital, less the investment. A positive NPV means the project beats the alternative use of the money.
Which should I use?
NPV for deciding whether to proceed, annualised ROI for comparing options, payback period for checking you can survive the wait. They answer different questions.
What discount rate is appropriate?
Your cost of capital, or the return available on the next best use of the money. For a small business that is often the return the business itself generates.
