13th-Month Pay Calculator
PD 851 made simple.
Total basic salary earned ÷ 12. Three inputs, live answer, ₱90K TRAIN ceiling applied automatically. Mid-year hires, fractional months, and unpaid leave all handled.
Your 13th-month pay, computed live.
PD 851 formula. Basic salary only — no allowances, OT, or holiday pay.
The cash basic — exclude allowances, COLA, OT, holiday pay, leave conversions
Fractional months OK — e.g., 6.5 for hire on Jun 15
Days that reduce earned basic salary
- Tax-exempt (TRAIN ₱90K ceiling)
- ₱35,000
- Subject to withholding tax
- ₱0
The ₱90K exemption is aggregate across 13th-month + other bonuses — if you've already received other bonuses this year, less of your 13th-month is exempt.
