The Average Daily Wage (ADW) is designed to protect employees of wage fluctuation by calculating wages earned over a period of 12 months. Once you have determined the days or for a 12-month period, the formula used to calculate ADW is:

[Wages earned (Full pay) - Wages earned (Non-full pay)] / 365 - [Number of days for Wages earned (Non-full pay)]

To fully understand the above ADW formula, here are some reference points that you can refer to:

  • Wages earned (Full pay) - the employee is fully paid for the day he/she worked.

  • Wages earned (Non-full pay) - any wages that are not paid in full for the days he/she worked; such as Sick Leave/Maternity Leave/Paternity Leave can be paid 4/5 of Average Daily Wage per day. If you have more non-full pay payments like Rest Day/Statutory Holiday/Annual Leave/Other payments, it will also fall under Wages earned (Non-full pay).

  • Number of days for Wages earned (Non full pay) - the number of days for wages not paid in full for the days he/she worked

Note: Previously, you will need to exclude full paid leave days, however the Amendment Ordinance has made a technical amendment* to help simplify the administrative work. For reference, you can view Note 9 in Page 6 of the Amendment Ordinance guide.

(*Amendment reference: To simplify the administrative work involved in calculating average wages, the Amendment Ordinance has made a technical amendment to presume the sum payable for the periods under (i) and (ii) as wages.

By doing so, an employer does not have to exclude his employee's full-paid leave (be it statutory holiday, annual leave, maternity leave or any other leave taken with agreement of the employer) as well as the sum paid correspondingly when calculating average wages. It is noteworthy that the definition of wages under EO has not been changed as a result of this amendment.)

How to calculate Average Daily Wage (ADW)?

Before referring to ADW calculation examples, you will need to know how to determine the days for ADW first. For example, assuming an employee is hired on the 1 January 2020:

Scenario #1


Total Wage: HKD$50,000

Payroll month: June 2020

Average Daily Wage payment for: 18 June 2020

Employment Duration: worked for only 6 months (which is less than the 12 month period)

Determining the number of days:

The Start Date of the period will be 1 January 2020 (employee's Hired Date). The End Date will be 31 May 2020.

The End Date is 31 May 2020 because the end date needs to be on the last day of the previous month. It helps to standardise the monthly payroll process, as payroll is usually calculated for the whole of June 2020.

Therefore, 1 Jan 2020 - 31 May 2020 = 152 days

Average Daily Wage (ADW) Calculation:

HKD$50,000 / 152 days = HKD$328.9473

Scenario #2


Total Wage (1st Feb 2020 - 31st Jan 2021): HKD$120,000

Payroll month: February 2021

Average Daily Wage payment for: February 2021

Employment Duration: 1st year or more

Sick Leave taken in June 2020: 2 days (payment is calculated based on 4/5 of ADW)

Determining the number of days:

Since January 2020 to February 2021 is more than 12 months, you will need to adjust and only use the current past 12-month period for ADW. Hence,

Start Date: 1 February 2020

End Date: 31 January 2021

The End Date needs to be on the last day of the previous month (31 January 2021).

Therefore, 1 February 2020 - 31 January 2021 = 365 days

(If there is a leap year with more than 365 days, you will need to use 365 days)

Average Daily Wage (ADW) Calculation:

ADW in June 2020: HKD$328.9473

To calculate sick leave payment of 4/5 of Average Daily Wage, the calculation is as below:

4/5 x HKD$328.9473 x 2 days = HKD$526.31568

ADW for February 2021:

[Wages earned (Full pay) - Wages earned (Non-full pay)] / 365 - [Number of days for Wages earned (Non-full pay)]

(HKD$120,000 - HKD$526.31568) / (365 days - 2 days) = HKD$329.1286069421
