BusinessCalc.io is a free utility site. We do not collect, store, or transmit any of the values you enter into a calculator. All calculations run in your browser; the numbers never leave your device.
Region preference
We save your last-selected region (USA, UK, or South Africa) in your browser's local storage so the calculator opens to the right currency and tax defaults next time. This data is stored on your device only and is not transmitted to us.
Analytics
We use privacy-friendly analytics to understand which calculators are most useful. We do not use cookies that track you across other websites and we do not sell or share data with third parties.
Display ads
This site is supported by display advertising. Ad networks may use cookies to personalise the ads you see. You can opt out of personalised advertising via your browser settings or your regional advertising preferences portal.
