In effect since 13 July 2007, a considerable number of companies in Hong Kong remain uninformed about the stipulations outlined in the Employment (Amendment) Ordinance 2007 (“the E(A)O 2007”). The primary aim of the 713 Ordinance is to ensure that all elements of wages, as defined in the Employment Ordinance, are considered when calculating relevant statutory entitlements. Here’s a concise guide around the calculation of the 12-month average wage as instructed in the 713 Ordinance.

Calculating Statutory Entitlements Using the 12-Month Average Wages

Annual leave (and other statutory leave e.g. maternity leave, sick leave) pay in Hong Kong is calculated from the average daily wages earned by an employee over a 12-month period. Refer below for details on how the 12-month period is determined.

The main purpose of the 12-month average wages calculation is to protect employees. Implementation of this calculation minimises the chance of unfair reduction of statutory entitlements that’s resulted from deflation of average wage.

Employers with large portions of sales staff who have a higher amount of variable or non-base salary benefits (e.g., commissions) are at higher risk of the chance of calculating Average Daily Wages incorrectly.  

The 12-month average wages is applicable to all employees covered by the Labour Ordinance regardless of how they’re rated (monthly, daily, or piece rated). It is used to calculate the following statutory entitlements:

  • Holiday pay
  • Annual leave pay
  • Sickness allowance and related provisions
  • Maternity leave pay and related provisions
  • Paternity leave pay
  • End of year payment
  • Payment in lieu of notice
  • Further sum for non-compliance of an order of reinstatement or re-engagement for unreasonable and unlawful dismissal

How the 12-Month Period of Average Wage is Calculated (713 Ordinance)

For employees who have been with the company for less than 12 months, the calculation should be measured on a shorter period. Regularly, the 12-month period will be calculated as follows:

Periods and Wages to be Disregarded

To avoid deflating the amount due for the statutory entitlement, periods where the employee is not paid the full wages, or any wages should be excluded. Wages from these periods are also excluded from the calculation.

This includes the following scenarios:

  1. The employee takes any of the following leave:
    • Leave provided under the Employment Ordinance 
      • Rest day
      • Statutory holiday
      • Annual leave
      • Maternity leave
      • Paternity leave
      • Sick days
    • Sick leave due to work injuries as provided under the Employees’ Compensation Ordinance
    • Leave taken with the agreement of the employer (no pay leave)

  2. A normal working day where the employee is not provided with work by the employer.

Under the Amendment Ordinance, the 12-month average wage should be calculated as follows.

Sample Calculation of Hong Kong 12 month average wage

To put it more simply, the 12-month average wage is the eligible wages divided by the total days for these wages (depicted below). With this figure, the employers can then calculate the pay due.
