Getting Started
This site provides a collection of calculators to help you with percentages, shopping discounts, tips, body measurements, financial planning and more. Results update automatically as you type – there’s no need to click a separate calculate button.
Using the Calculators
- Move between fields: You can use the Tab key to jump to the next input and Shift + Tab to return to the previous one.
- Auto‑calculate: Results appear immediately after you enter values. If you prefer to use the keyboard, pressing Enter will also trigger an update.
- Decimal separators: Both the dot (
.) and comma (,) are accepted as decimal points. Do not use thousands separators – numbers like1,000will be interpreted as1.000. - Units: For health calculators you can choose between metric (kilograms/centimetres) and U.S. units (pounds/inches). Values entered in U.S. units are converted internally.
- Copy results: Click the Copy button next to any result to copy just the numeric value to your clipboard.
- History: Your last ten calculations are saved in your browser. Use the Clear button in the History section to reset the list.
Accessibility
We aim to make the calculators usable for everyone. All inputs are properly labelled, results are announced via screen readers using ARIA live regions, and keyboard focus styles are visible. If you encounter any accessibility barriers, please contact us.
