The 13th month pay formula
Presidential Decree No. 851 defines 13th month pay as one-twelfth (1/12) of the total basic salary earned within the calendar year. In practice:
13th month pay = (Monthly basic salary × months worked − unpaid absences) ÷ 12
"Basic salary" means what you are paid for services rendered. According to the DOLE Handbook on Workers' Statutory Monetary Benefits, it excludes overtime pay, premium pay, night shift differential, holiday pay, cost of living allowance (COLA), and the cash value of unused leave — unless these are integrated into your basic pay by contract, collective bargaining agreement, or company practice.
Worked examples in pesos
Example 1 — full year. Maria earns ₱25,000 basic per month and worked all 12 months of 2026. Total basic salary = ₱25,000 × 12 = ₱300,000. 13th month pay = ₱300,000 ÷ 12 = ₱25,000.
Example 2 — new hire. Jun started on April 1, 2026 at ₱18,000 per month, so he works 9 months. Total basic = ₱162,000. 13th month pay = ₱162,000 ÷ 12 = ₱13,500.
Example 3 — with unpaid absences. Ana earns ₱30,000 per month for 12 months but had ₱6,000 in leave-without-pay deductions. Total basic = ₱360,000 − ₱6,000 = ₱354,000. 13th month pay = ₱29,500.
Example 4 — minimum wage earner. A worker paid the NCR daily minimum wage of about ₱695 for 26 days a month earns roughly ₱18,070 per month. For a full year, 13th month pay ≈ ₱18,070.
