Comprehensive Guide: How to Calculate 13th Month Pay in 2024
The 13th month pay is a mandatory benefit in many countries, particularly in Southeast Asia, designed to provide employees with additional financial support during the holiday season. This guide explains everything you need to know about calculating your 13th month pay accurately, including legal requirements, computation methods, and common misconceptions.
What is 13th Month Pay?
The 13th month pay is an additional monetary benefit equivalent to one month’s basic salary, typically paid out in November or December. It was introduced to help employees with holiday expenses and is now a standard benefit in many labor laws.
- Philippines: Mandatory under Presidential Decree No. 851 (1975)
- Indonesia: Known as “Tunjangan Hari Raya” (THR), mandatory for employees with ≥1 year service
- Malaysia: Not mandatory but commonly provided as a bonus
- Singapore: Not legally required but widely practiced
Legal Basis for 13th Month Pay
In the Philippines, the legal foundation for 13th month pay is established by:
- Presidential Decree No. 851 (1975) – Mandates payment of 13th month pay to all rank-and-file employees
- Labor Code of the Philippines (Article 87) – Defines the computation and payment terms
- DOLE Labor Advisory No. 13, Series of 2020 – Clarifies computation during the COVID-19 pandemic
For authoritative information, refer to the Philippine Department of Labor and Employment (DOLE) official website.
Step-by-Step Calculation Process
1. Determine Your Basic Salary
The computation is based on your basic monthly salary only. This excludes:
- Overtime pay
- Holiday pay
- Night differential
- Commissions
- Allowances (transportation, meal, etc.)
2. Calculate Total Months Worked
Count the number of months you’ve worked from January to the payment date. For new employees:
- If employed before the cutoff date: Count all months
- If employed after cutoff: Pro-rate based on months worked
3. Compute the Pro-Rata Amount
The formula for pro-rated 13th month pay:
(Monthly Basic Salary × Number of Months Worked) ÷ 12
4. Deduct Unpaid Leaves
For each unpaid leave day, deduct 1/22 of your monthly salary from the total:
Unpaid Leave Deduction = (Monthly Salary ÷ 22) × Number of Unpaid Days
5. Final Computation
The complete formula:
13th Month Pay = [(Monthly Salary × Months Worked) ÷ 12] - Unpaid Leave Deduction
Common Scenarios and Examples
| Scenario | Monthly Salary | Months Worked | Unpaid Leaves | 13th Month Pay |
|---|---|---|---|---|
| Full year employment | ₱25,000 | 12 | 0 | ₱25,000 |
| 6 months employment | ₱20,000 | 6 | 0 | ₱10,000 |
| Full year with 5 unpaid leaves | ₱30,000 | 12 | 5 | ₱28,636.36 |
| Part-time (20 hrs/week) | ₱15,000 | 12 | 0 | ₱15,000 |
Tax Implications
In the Philippines, 13th month pay and other benefits (up to ₱90,000) are tax-exempt under Republic Act No. 10653. However:
- Amounts exceeding ₱90,000 are subject to income tax
- Different tax rules apply in other countries (e.g., Indonesia taxes THR for high earners)
- Always consult with your HR or a tax professional for accurate advice
Frequently Asked Questions
Is 13th month pay mandatory for all employees?
In the Philippines, it’s mandatory for rank-and-file employees but not for managerial employees (though many companies provide it voluntarily). Other countries have different rules:

| Indonesia | Yes | 12 months | Before religious holiday |
| Malaysia | No | Varies | Company policy |

What if I resigned before the payout date?
You’re still entitled to a pro-rated 13th month pay based on the months you worked. The computation remains the same as shown in our calculator.
Does 13th month pay affect my regular salary?
No, it’s an additional benefit and doesn’t reduce your regular monthly salary. It’s calculated separately from your normal compensation.
