About this free return on investment (roi) tool
Calculate profit and percentage return from cost and final value. Calculators answer a defined arithmetic question using the values you supply. Keep units and currencies consistent, choose the correct starting amount and inspect the assumptions before using a result. Estimates do not replace a lender quotation, an official tax rate, a medical assessment or a jurisdiction-specific deadline rule.
A practical example

Before you rely on the result
Use one currency throughout. This is an arithmetic estimate, not financial, tax or legal advice; actual rates, fees and terms may differ.
