About Anubis Calc
Last updated:
Anubis Calc (calculatoranubis.com) is a dedicated platform of free online calculators in Arabic and English. Our goal is simple: you type a number, you get the right answer immediately, and you can see exactly how it was worked out with its formula and official sources.
Founder & Financial Reviewer
Anubis Calc is founded and reviewed by Mr. Behairy — Accountant, Financial Auditor, and Tax Specialist. Every financial, tax, salary, loan, and zakat calculator is audited against official statutory rules and standard accounting principles before publication and whenever regulations change. Read our Editorial & Review Policy for full details on our verification process.
What makes these calculators different
- Keyboard-first. Every field is a real input you can type into, including Arabic digits (٠–٩). The scientific calculator works entirely from the keyboard.
- Formulas you can check. Each page explains the formula, gives a worked example with real numbers and lists its official sources.
- Tested. Every formula has automated tests with known correct answers, and the site cannot be published if a test fails.
- Private. Calculations run on your own device. We do not have a database of what people calculate.
- Arabic and English. Pages are written natively for each language and tailored to country-specific regulations.
How the site is funded
The calculators are free and supported by advertising from Google AdSense. Ads are never placed inside a calculator or next to its buttons and results.
