About HASEBA
Last updated 13 November 2026
HASEBA is a free collection of calculators and converters for everyday and business tasks in the United Arab Emirates, in English and Arabic.
What you can do here
Add or remove UAE VAT, convert property sizes, work out percentages, profit margins and markups, and count the days between two dates. Every tool works without an account, on a phone or a computer, in light or dark mode.
How we build each tool
Before a tool is published, we write down its formula, its rounding and its limits, and test it against worked examples calculated by hand. Tools that depend on UAE rules, such as VAT, cite the official sources we relied on and show the date we last checked them.
Your numbers stay on your device
The calculations run in your browser. The numbers you type are not sent to us and are not stored. The privacy policy explains the limited technical information our hosting receives.
Independent
HASEBA is independent. It is not a UAE government service and is not affiliated with the Federal Tax Authority or any other authority. Results are for information only; see the disclaimer.
