Frequently asked questions
Are the calculators free?
Yes. Calcora’s calculators are free to use in your browser, with no account required.
Are my calculator inputs uploaded?
Calculator inputs are processed on your device and are not sent to a Calcora server. Avoid entering sensitive personal or financial information into any website.
What information is saved in my browser?
Your favorites, theme, selected display currency, and cached exchange-rate data may be saved in your browser storage. You can remove this data by clearing site data in your browser settings.
How accurate are the results?
Results depend on the values, units, rounding, and assumptions shown by each calculator. Check important results independently before acting on them.
Are finance or health results professional advice?
No. These tools provide general estimates and educational information. They do not replace advice from a qualified financial, medical, legal, or other professional.
How current are currency exchange rates?
The currency converter retrieves indicative rates from ExchangeRate-API. The provider updates its open access rates about once a day. Rates may differ from the amount offered by a bank, card provider, or exchange service.
Does the currency selector convert my calculator inputs?
In finance calculators, the display currency selector changes the currency symbol and code shown with results; it does not convert entered amounts. Use the Currency Converter for an exchange between currencies.
Can I install Calcora as an app?
Use the Install app button when your browser offers installation. On iPhone or iPad, open the site in Safari, tap Share, then Add to Home Screen.
Can I use the site without internet?
Some pages and tools may be available after the site has loaded and been cached by your browser. Live exchange rates require an internet connection.
How do I report a problem or suggest a calculator?
