How is the leave indemnity calculated after resignation?

Hello Dear,

Greetings for Day.

I'm S. working in Bahrain right now. I'm working with a company for 3 years and 2 months.

When I joined here, my salary was BD160. Then after that, I got promoted with BD 30 more. Total is BD 190. After that, I got again BD 30. Now my total salary is BD 220.

I gave my resignation letter last month. In this case, how much should I get? How is the process?

Please let me know if you like to help me.

Thank you
