Estimates only, not financial advice. What you type stays on your device. Checked against sources on 16 Oct 2026.

Someone who joined or left during the year still gets a 13th month pay in the Philippines: one twelfth of the basic salary actually earned in the calendar year, under PD 851. Six months at ₱25,000 is ₱150,000 earned, so the 13th month pay is ₱12,500. A resigned employee receives it with the final pay; unpaid absences come off the salary earned first.

How Prorated 13th Month Pay Calculator works

Every rank-and-file employee in the Philippines who worked at least a month in the year is owed a 13th month pay by 24 December. This page computes it the way the law defines it.

The rule (PD 851). The 13th month pay is one twelfth of the basic salary an employee earned within the calendar year. Basic salary is the pay for work done. Cost-of-living allowances, profit-sharing and allowances that are not part of the basic salary do not count. Overtime, holiday and night-shift premiums are usually left out too, unless your employer's practice includes them.

Pro-rated by itself. Because it is a twelfth of what you earned this year, someone who joined in April or resigned in September gets a smaller amount without any extra step. Unpaid absences and tardiness lower the salary earned, so they lower the 13th month pay as well.

Frequently asked questions

How do I compute 13th month pay?

Add up the basic salary you earned from January to December, after deductions for unpaid absences, and divide by 12. On ₱25,000 a month for the whole year that is ₱300,000 / 12 = ₱25,000.

How is 13th month pay prorated for a new or resigned employee?

The same rule does it: one twelfth of the basic salary earned in the calendar year. Six months at ₱25,000 is ₱150,000 earned, so ₱12,500. A resigned employee receives it with the final pay.

When must the 13th month pay be given?

Not later than 24 December. An employer may pay half before the school year opens and the rest by 24 December; a union agreement can set another schedule. The amount is one twelfth of the basic salary earned in the calendar year.

Who is entitled to 13th month pay?

All rank-and-file employees in the private sector who worked at least one month during the calendar year, whatever their salary or how they are paid. Managerial employees and government workers are not covered by PD 851.
