1Understanding Overtime Rates & Multipliers

Standard labour regulations in Cambodia and most international jurisdictions define standard working hours as 8 hours per day (48 hours per week). Any work performed beyond standard daily hours or on weekly rest days is classified as Overtime (OT) and requires higher pay multipliers:

1.0x

Standard Work Hours

Regular Monday–Friday or Monday–Saturday shifts up to 8 hours daily. Paid at 100% standard hourly wage.

1.5x

Regular Weekday Overtime

Additional hours worked after normal daily 8 hours on regular workdays. Paid at 150% of base hourly wage.

2.0x

Sunday & Public Holiday OT

Work performed on weekly rest days (Sundays) or official public holidays. Paid at 200% of base hourly wage.


2Key Formulas to Use in Microsoft Excel & Google Sheets

When building your own timesheet in Excel or Google Sheets, use these essential formulas to calculate hours and earnings automatically:

1. Calculate Total Working Hours (Clock Out − Clock In)
=IF(E2>D2, (E2-D2)*24 - F2, 0)
Where D2 = Time In, E2 = Time Out, and F2 = Lunch Break Hours.
2. Separate Standard Hours vs 1.5x Overtime
=MIN(8, TotalHours)
=MAX(0, TotalHours - 8)
Automatically caps standard daily hours at 8 and puts excess hours into Overtime.
3. Calculate Total Daily Gross Pay ($)
=(StandardHrs * HourlyRate) + (OT15 * HourlyRate * 1.5) + (OT20 * HourlyRate * 2.0)
