This Gratuity Calculation is only base in Qatar Country

(Basic Salary Per Month) Divide into 30(number of days in month) X 21 Days = 1 Year Gratuity Bunos

Like for example:
If your working for 5 years and your basic salary is 4,500 Qatar Riyals then this is the computation

In Qatari Law, 1 year end of service will be payed 21days salary. Basically this how it goes.

4500 Qatari Riyals(salary per month) divide into 30(days in a month)= 150QR X 21days(1 year end of service gratuity)= 3,150 Qatari Riyals

3,150 Qatari Riyals X 5(years you work)= 15,750

(Your Gratuity in 5 years if your salary is 15,750 Qatari Riyals)

Thanks...
