About SmartCalcy

What SmartCalcy is

SmartCalcy is a free set of calculators and converters for everyday sums: money and currency, loans and mortgages, health and fitness, dates and time, cooking, DIY, maths, text and more. Open a tool, type, and get the answer.

How it works

Everything runs in your browser and there is no account or sign-up. Tools use your region’s currency, units and date format, and the site is available in English, Spanish, French, Dutch, German, Portuguese and Italian.

Where the data comes from

Exchange rates, crypto and metal prices, public holidays and word lists come from open datasets and public price services. The credits are listed at the bottom of every page.

Accuracy

Results are estimates for information only. They are not financial, medical, legal or professional advice, so check official guidance before you rely on a result.
