Understanding the results
The summary separates the most important output from supporting values. Currency selection changes formatting only; it does not convert exchange rates or alter a currency-independent formula.
Frequently asked questions
Why can ROI and IRR give different answers?
Total invested cost is the denominator. Annualized ROI compounds the positive ending-net-value ratio over the entered duration. The result depends on the values and assumptions entered, so compare it with the applicable provider or official rule.
Can I use decimal values in the ROI Calculator?
Yes. Decimal values are supported. Results are calculated at full JavaScript numeric precision and formatted for readability.
Are the ROI Calculator results guaranteed?
No. The calculator provides an estimate based on the entered assumptions and is not financial, tax, investment, lending, payroll, or legal advice.
