Computation of Pro-rated 13th Month Pay for Employees on Maternity Leave

Under Philippine labor laws, the 13th-month pay is a mandatory benefit, and its computation becomes a point of frequent inquiry when an employee undergoes maternity leave. Understanding the intersection of Presidential Decree No. 851 and Republic Act No. 11210 (The 105-Day Expanded Maternity Leave Law) is essential for compliance.


The Statutory Basis

The 13th-month pay is defined as one-twelfth (1/12) of the total basic salary earned by an employee within a calendar year. "Basic salary" includes all remunerations or earnings paid by an employer for services rendered, but generally excludes allowances and monetary benefits which are not considered part of the regular salary (such as unused vacation/sick leave credits, overtime pay, and night shift differentials).

The Impact of Maternity Leave on "Total Basic Salary"

The core principle in computing the 13th-month pay for an employee who took maternity leave is that the benefit is based on actual service rendered and wages paid by the employer.

  1. Exclusion of SSS Maternity Benefits: The maternity benefit received from the Social Security System (SSS) is not considered part of the "total basic salary." It is a social security benefit, not compensation for services rendered.
  2. Salary Differential: Under R.A. 11210, employers in the private sector are required to pay the salary differential (the difference between the employee’s actual full salary and the SSS maternity benefit). The Department of Labor and Employment (DOLE) clarifies that this differential is also excluded from the "total basic salary" for the purpose of 13th-month pay computation.
  3. Pro-rated Nature: Because the employee is not "rendered service" during the 105 days (or 120 days for solo parents) of maternity leave, the months or days spent on leave are effectively unpaid by the employer in terms of "basic salary." Consequently, the 13th-month pay is naturally pro-rated.

The Computation Formula

To arrive at the correct amount, the employer must sum all basic salary payments actually received by the employee during the calendar year and divide the total by 12.

$$\text{13th Month Pay} = \frac{\text{Total Basic Salary Earned within the Calendar Year}}{12}$$

Illustrative Example

An employee with a monthly basic salary of ₱30,000 takes the full 105 days of maternity leave.

  • Months Worked: Assume the employee worked for 8.5 months of the year and was on maternity leave for 3.5 months.
  • Total Basic Salary: $₱30,000 \times 8.5 = ₱255,000$
  • Computation: $₱255,000 / 12 = ₱21,250$

In this scenario, the employee receives ₱21,250 as her 13th-month pay, rather than the full ₱30,000 she would have received had she worked the entire year.


Key Legal Guidelines for Employers

  • Deadline for Payment: The 13th-month pay must be paid no later than December 24 of each year.
  • Resignation or Termination: If an employee resigns or is terminated after coming back from maternity leave, she is still entitled to the pro-rated 13th-month pay earned during the time she was physically working.
  • Minimum Service Requirement: To be entitled to the benefit, the employee must have worked for at least one (1) month during the calendar year.
  • Non-Diminution of Benefits: If a company has a pre-existing policy or Collective Bargaining Agreement (CBA) that treats maternity leave as "paid service" for 13th-month purposes, the employer must honor that more favorable practice.

Summary Table: Inclusion vs. Exclusion

Component Included in 13th Month Computation?
Monthly Basic Salary (Active Months) Yes
SSS Maternity Benefit No
Employer Salary Differential No
Overtime & Night Differential No
Pro-rated Service (Actual Days Worked) Yes

While the law protects the tenure and status of employees on maternity leave, the 13th-month pay remains a reflection of productivity and actual wages earned. Employers must ensure that payroll systems accurately reflect these exclusions to avoid overpayment or underpayment disputes.
