Free online calculators and converters for everyday sums: split a bill, convert metres to feet, count the days between two dates, work out a loan repayment. No sign up, and nothing you type is ever sent to us. Open a tool, get your answer, close the tab.
The Tip Calculator splits a restaurant bill between however many of you there are. The Discount Calculator works out a sale price, and the VAT Calculator checks a figure. The Percentage Calculator handles the everyday sums you half remember from school. The Unit Converter turns metres into feet and grams into ounces, while the Cooking Measurement Converter changes cups to grams and the Recipe Scaler scales a recipe up for eight people.
Dates are where people trip up, because counting across a calendar by hand quietly loses a day. The Date Difference Calculator tells you how many days sit between two dates, Add or Subtract Days from a Date moves a deadline forward or back, and the Age Calculator gives an exact age down to the day. If you are arranging something across countries, the Time Zone Converter and the Meeting Time Planner do the hour shifting for you.
Salary figures, loan amounts and health numbers are nobody else's business, so everything happens on your own phone or computer. The Loan Calculator, Compound Interest Calculator and BMI Calculator work out your answer right where you typed it, and the Currency Converter needs no account either. You never sign up, nothing you type is ever sent to us, and no cookies follow you afterwards. Nothing is stored, so there is nothing to clean up.
Yes, every calculator and converter here is free with no limits. You do not need to register, give an email address, or start a trial, and there is no paid version that unlocks extra features. There is no cap on how many calculations you can run or how often you come back. The tools are plain web pages, so you can bookmark the ones you use most and open them straight away next time.
With these tools, yes, because the numbers never leave your device. Every calculator does its working out on your own phone or computer, so the figures you type into the Loan Calculator, BMI Calculator or Compound Interest Calculator stay with you and are never sent to us. Nothing is logged, stored or shared, and refreshing the page clears everything. Many other calculator sites send your numbers off to their own computers, or load advert trackers alongside them, which is a very different situation.
Mostly yes. Once a tool has opened, the sum itself is worked out on your device, so a Percentage Calculator, Unit Converter or Pomodoro Timer keeps working if your connection drops. The exception is the Currency Converter, which needs a connection to look up up-to-date exchange rates. You do need to be online for the page to load the first time, but after that nothing else is fetched.
