Every employee in the Philippines looks forward to the 13th-month pay—that extra salary bonus required by law. But many workers still ask: “How do I know the exact amount I’ll receive?”
That’s where the 13th Month Pay Calculator Philippines 2025 comes in. It gives a clear, accurate estimate of your bonus using your total basic salary and the latest labor-law guidelines.
In this guide, we’ll explain what 13th-month pay is, how it’s computed, who’s entitled to receive it, and how online calculators make the process simple and transparent.
What Is 13th Month Pay?
Under Presidential Decree No. 851, all rank-and-file employees in the Philippines who have worked for at least one month are entitled to receive a 13th-month pay.
It is equal to one-twelfth (1/12) of the employee’s total basic salary earned within the year.
Formula:
13th-Month Pay = Total Basic Salary Earned for the Year ÷ 12
Example:
If your total basic salary from January to December is ₱480,000, your 13th-month pay will be ₱40,000.
Why Use the 13th Month Pay Calculator Philippines 2025?
Manual computation can be confusing, especially if you’ve had unpaid leaves or partial months of work.
The 13th Month Pay Calculator automates the process—just input your monthly salary, and it instantly displays your estimated bonus.
Key Benefits:
- Accurate calculation based on updated rules
- Saves time compared to manual computation
- Useful for verifying if your employer paid the correct amount
- Great for budget planning during the holiday season
Computation Guide for 2025
Let’s break it down step by step using an example salary.
| Month | Basic Salary (₱) |
|---|---|
| January–December | 40,000 each month |
Step 1: Add up all basic salaries.
₱40,000 × 12 = ₱480,000
Step 2: Divide by 12.
₱480,000 ÷ 12 = ₱40,000
✅ Your 13th-month pay = ₱40,000
If you joined mid-year or had unpaid leave, the calculator adjusts automatically.
For instance, if you worked only 6 months (₱240,000 total), your 13th-month pay = ₱240,000 ÷ 12 = ₱20,000.
Taxability and BIR Rules (Updated 2025)
According to the BIR Income Tax Calculator Philippines (Updated 2025) guidelines:
- 13th-month pay and other benefits are tax-exempt up to ₱90,000.
- Any amount beyond ₱90,000 is subject to income tax.
Example:
If your 13th-month pay is ₱100,000, only ₱10,000 will be taxed.
This exemption encourages employees to maximize their holiday bonus legally and transparently.
Who Are Entitled to 13th Month Pay?
You are entitled if:
- You are a rank-and-file employee (no managerial position).
- You worked for at least one month during the calendar year.
- You receive a monthly basic salary, not commission-based income.
Freelancers, consultants, and project-based workers are not entitled under this law—but they can simulate a bonus using the Freelancer Tax Calculator Philippines to project their year-end earnings.
Mandatory Deductions vs. 13th Month Pay
Your 13th-month pay is computed based on basic salary, so it does not include allowances, overtime, or benefits. However, it may be subject to the same deductions as your regular salary, such as:
- SSS Contribution → check the SSS, PhilHealth & Pag-IBIG Contribution Calculator
- PhilHealth Contribution
- Pag-IBIG Fund Contribution
- Withholding Tax (BIR)
Understanding these deductions along with your 13th-month pay gives you a complete view of your income distribution.
How Employers Compute and Distribute the 13th Month Pay
Employers must release the 13th-month pay on or before December 24 every year. Some companies offer it in two installments (June and December) for better cash-flow management.
The Department of Labor and Employment (DOLE) strictly monitors compliance, so employers who fail to pay may face penalties or employee complaints.
