Free calculators for work, money, health and dates
Work out the numbers that matter in daily life and at work. The Gulf calculators, such as UAE gratuity, Saudi end of service, annual leave and VAT, follow the published law and show the article and the date they were checked. The general calculators work anywhere in the world. Nothing you type is stored, and there is no sign-up.
Quick answer
To work out what you are owed when a job ends, use the UAE gratuity calculator or the Saudi end-of-service calculator; for leave pay and daily or overtime pay, use the annual leave and salary calculators. For money decisions there are VAT, loan, mortgage, rent, gold and fuel calculators, and for everyday sums the percentage, discount, unit, BMI, age and date calculators.

Questions
Are the gratuity and end-of-service results official?
They follow the published labour law and show the article used, but they are estimates. Your employer or the labour ministry gives the official figure.
Where do the gold prices come from?
From an international spot price feed, updated hourly and shown with its time. Shop prices add making charges and VAT.
Is anything I enter saved?
No. The calculators run in your browser and nothing you type is stored.
Do the calculators work outside the Gulf?
The percentage, loan, BMI, age and date calculators work anywhere. Gratuity, end of service and VAT follow UAE or Saudi rules.
Can I trust the health calculators?
They use standard formulas such as the WHO BMI categories, but they are not a diagnosis. Ask a doctor about your health.
