How to Compute 13th Month Pay in the Philippines (2026 DOLE Formula)
Every rank-and-file employee in the Philippines is entitled to a 13th month pay under Presidential Decree 851. As of 2026, the rule remains unchanged: 13th month pay = total basic salary earned during the calendar year ÷ 12. The Department of Labor and Employment (DOLE) mandates employers to release it on or before December 24. Whether you’re a full-time employee, a part-time worker, or resigned mid-year, our 13th month pay calculator Philippines helps you compute accurate figures — including prorated amounts and absences.
✅ Basic formula (with examples)
Total basic salary includes all compensation for services, excluding allowances, overtime, holiday pay, and 13th month itself. For an employee who worked the full year with monthly salary ₱25,000: Total basic = ₱300,000 → 13th month = ₱300,000 ÷ 12 = ₱25,000.
For prorated 13th month pay calculator (resigned or started mid-year):
Example: Maria worked from March to December (10 months) with ₱30,000/month → total basic = ₱300,000 → 13th month = ₱25,000 (same as full year? Wait, compute: 300,000 ÷ 12 = ₱25,000). Actually formula always divides by 12, so it’s proportional to total earned salary. If you worked only 5 months at ₱20,000/month = ₱100,000 total basic → 13th month = ₱100,000 ÷ 12 ≈ ₱8,333.33.
📉 Impact of unpaid absences on 13th month pay
Many employees ask: how to calculate 13th month pay with absences? Since the base is “total basic salary earned,” any unpaid leave reduces total earnings. If an employee has 5 days of unpaid leave, the daily rate reduces total salary. Daily rate for monthly-paid = (Monthly salary × 12) ÷ 261 working days per year (DOLE standard factor). Our calculator automatically deducts unpaid days using this factor, giving you a precise 13th month pay calculator with absences.
| Monthly Salary | Months Worked | Unpaid Days | Total Basic Earned | 13th Month Pay |
|---|---|---|---|---|
| ₱22,000 | 12 | 0 | ₱264,000 | ₱22,000.00 |
| ₱28,000 | 8.5 | 2 | ₱235,509* | ₱19,625.75 |
| ₱35,000 | 6 | 0 | ₱210,000 | ₱17,500.00 |
| ₱18,500 | 12 | 4 | ₱218,612 | ₱18,217.67 |
