Practical Guide to Partial Month Wages for Foreign Domestic Helpers: Stop Overpaying Your Final Payout
⚡Quick Summary
|
When your foreign domestic helper contract ends—whether it reaches its full two-year expiry or you terminate helper services early—the standard ID407 contract does not explain how to calculate final pay. The Hong Kong Labour Department provides a sample receipt template (Sample Receipt for Payments upon Termination/Completion of Employment Contract), but it is only a blank document to record final figures, not a calculator.
A single math error or misapplied rule can lead to underpaying your helper, resulting in statutory fines or legal disputes at the Hong Kong Labour Tribunal under the Employment Ordinance (Cap. 57).
This guide provides clear, step-by-step rules and statutory formulas to calculate your helper's final payout accurately.
The Legal Rule: Cap. 1 vs. Contractual Monthly Wages
Under Section 3 of the Interpretation and General Clauses Ordinance (Cap. 1), a "month" is strictly defined as a calendar month. For a monthly-salaried foreign domestic helper, their wages are tied directly to that specific calendar block—regardless of whether the month has 28, 29, 30, or 31 days.
When a contract is cut short mid-month, the basic monthly wage must be broken down proportionally (pro-rated). Under traditional common law and contractual principles in Hong Kong, this calculation must anchor itself strictly to the actual number of calendar days in that specific month:
Using this legally sound calendar approach, the exact value of a single day’s work changes based on the month:
February (28 days): One day is worth 1/28 of the monthly salary.
March (31 days): One day is worth 1/31 of the monthly salary.
This ensures simple, logical math: if your helper works exactly 14 days out of February's 28 days, they receive exactly 50% of their monthly contract wage.
The Agency Error: Misapplying Average Daily Wage (ADW)
Agencies frequently bypass this calendar method. Instead, they apply a single, fixed daily rate across the entire final settlement receipt using the Average Daily Wage (ADW) framework from the Employment (Amendment) Ordinance 2007.
This is a major legal misstep. The Employment Ordinance (Cap. 57) explicitly restricts the 12-month ADW formula to eight specific statutory items:
Statutory holiday pay
Annual leave pay
Sickness allowance
Maternity leave pay
Paternity leave pay
End-of-year payments
Notice pay (wages in lieu of notice)
Severance or Long Service payments
The law is completely silent on using ADW to calculate basic contractual monthly wages for an incomplete month. Because Cap. 57 explicitly lists where ADW applies, agencies cannot legally stretch it to cover basic contractual payroll.
Financial Trap: Why You Overpay in 31-Day Months
Blindly accepting an agency's single daily rate creates an unfair financial loss for employers due to basic probability.
The calendar year is heavily weighted toward longer months: 7 out of 12 months have 31 days (January, March, May, July, August, October, and December). Out of 365 days in a standard year, 217 days fall inside a 31-day month.
This means there is a 59.45% probability—well over half—that a mid-month contract termination will happen in a 31-day month.
When you use the legally required calendar method during a 31-day month, the daily wage rate drops because the fixed salary is divided by 31 instead of 30 or 365/12. Legally speaking, this lower daily rate means a lower payout for partial months.
Let’s look at a real example using a standard monthly salary of HK$5,100:
Agency Flat ADW Method: Artificially locks the daily wage at HK$167.67(HK$5,100 x 12 ÷ 365) every single day of the year.
Legally Compliant Calendar Method (31-day month): The true daily wage drops to HK$164.52 (HK$5,100 ÷ 31).
By erasing calendar variations, standard agency templates strip away your right to a lower daily wage for almost 60% of the year. This forces you to overpay for partial-month wages during January, March, May, July, August, October, and December.
The February Warning: Underpayment & Criminal Liability
While agency shortcuts cause you to overpay for most of the year, the situation completely reverses in February—creating severe legal risks.
In a non-leap February (28 days), the daily wage rate increases because the fixed salary is spread across fewer days (HK$5,100 ÷ 28) = HK$182.14.
If a contract ends mid-February, the agency's flat rate HK$167.67(HK$5,100 x 12 ÷ 365) underpays the helper's legal wages:
Example: Helper works 14 days in February:
True Legal Payout: 14 days x HK182.14=HK$2,550 (Exactly half a month's wage)
Agency Flat Payout: 14 days x HK$167.67=HK$2,347.38
Shortfall: You underpay your helper by HK$202.62.
Under the Employment Ordinance (Cap. 57), failing to pay full contractual wages within 7 days of termination is a serious criminal offense. Underpaying your helper exposes you to statutory interest charges, Labour Tribunal claims, and criminal fines.
The Correct Method: The Two-Pillar Final Settlement
To protect your wallet and ensure complete legal compliance, reject all-in-one agency templates. Always split your foreign domestic helper's final settlement into two distinct pillars:
Pillar A: Basic Contractual Salary (Incomplete Month) | Pillar B: Statutory Payouts (Annual Leave, Statutory Holidays, Notice Pay) |
Calculate basic partial wages using the exact calendar days of that specific month under Cap. 1 (e.g., divide by 31 for March, 28 for February). | Calculate statutory entitlements strictly using the 12-month ADW formula as mandated by Cap. 57. |

Frequently Asked Questions (FAQ)
1. Can I use the 365-day formula if my helper agrees to it in writing?
No. Standard employment terms in Hong Kong are governed by the Standard Employment Contract (ID407) and Hong Kong ordinances. Private agreements that provide less than statutory or contractual entitlements under Cap. 57 are legally unenforceable.
2. Which payouts MUST use the Average Daily Wage (ADW)?
Under Cap. 57, ADW must be used strictly for:
Statutory holiday pay
Paid annual leave
Sickness allowance
Maternity/paternity leave pay
Payment in lieu of notice
Severance or Long Service Payment
3. What is the deadline to pay the final wage settlement?
Under Section 25 of Cap. 57, all final wages and statutory payouts must be paid as soon as practicable, and no later than 7 days after the date of contract termination.
