About Calc4everyday

Calc4everyday is a small collection of calculators for everyday questions: how many feet are in a meter, what 15% of a price is, how much a loan will cost and how many days are left until a date.

Your data stays with you

Every calculation runs in your browser. The numbers you type are never sent anywhere, and the site sets no cookies and loads no third-party scripts, fonts or counters. Once a page has loaded it keeps working even offline.

Accuracy

Unit factors follow international definitions, and the financial calculators use the standard formulas described on each page. Results are for reference: banks and lenders may round differently, count interest by days or add fees.
