Overtime is calculated on an hourly basis, so how to calculate the base hourly rate for an employee working Monday-Friday 9am-6pm and earning 12k a month?

12k a month would be 69.23 baht an hour wouldnt it..

9-6 5 days a week = 45 hrs - 1 hr per day for lunch = 5hrs 45 - 5 = 40hrs.

12k a month X 12 months / 52 weeks / 40 hrs = 69.23

feel free to correct me if im wrong.

Thanks, v8tfcorty. I never thought about multiplying by 12 months and dividing by 52 weeks. Let's see if anyone knows whether this is the official way of doing it for payroll/accounting purposes

It's not.

There is a complicated method used by large companies.

Ok, start from the hourly overtime rate (that is not same as simple division of salary and hours worked). It is that minus benefits (leave, health insurance, pension...etc) and is lower than what one would think.

Then, hours of the day are not the same. 18-22 is hourly rate + 25% of it....22-24 is 50%...00-05 is 100%....05-09 is 25%...

Then, same dance for weekends.

Another dance for public holidays.

Another for being on call even if nothing happens.

Then, same thing if something did happen.

Then, what hours of day did happen?

Then, was it a weekend? Publuc holiday?

Was it less than 12 hrs or more?

You see....if you still think this board will teach you.....

I plan(ned) to offer 1.5 for extra hours worked weeknights (after 6 pm) and weekends, and 2.0 times for public holidays. Is that not according to the law? I'd rather keep it simple for my employees, so they can follow the formula easily and know they're not being cheated.

This is far more important than working out complicated formula and getting the wage exact.

Thanks, Lucifer. Hope you're not just playing Devil's Advocate.
