Philippine 13th Month Pay Calculator
Calculate your statutory gross 13th month pay, pro-rated amounts, ₱90k TRAIN tax-exempt limit, and estimated net take-home pay under DOLE PD 851.
13th Month Calculation Inputs
₱30,000
Legal Formula (PD 851):
Gross 13th Month = ₱360,000 ÷ 12 = ₱30,000
Calculation Formulas & Steps
1. Sum Eligible Basic Salary
Aggregate all basic salary earned for actual work performed in the calendar year (deducting unpaid absences).
2. Divide by 12 (Gross 13th Month Pay)
Divide total basic salary by 12 (regardless of whether you worked 12 full months or a fraction of the year). There is no statutory ceiling on the gross amount.
3. Apply ₱90,000 Tax-Exempt Ceiling
Under the TRAIN Law (RA 10963, Sec. 32(B)(7)(e)), total 13th month pay and other statutory benefits up to ₱90,000 are 100% exempt from income tax.
4. Compute Tax on Excess (> ₱90,000)
Any excess amount above ₱90,000 is added to your taxable income and taxed at your applicable BIR marginal bracket in year-end payroll.
Assumptions & Rules
- Follows Presidential Decree No. 851 and DOLE guidelines.
- Mandatory for all rank-and-file employees who have worked at least one (1) month during the calendar year.
- No salary ceiling exists for eligibility (the original ₱1,000 cap was repealed by Memorandum Order No. 28 in 1986).
- Must be paid on or before December 24 of each year (or upon separation).
Exclusions & Edge Cases
- Excludes overtime pay, night shift differential, holiday pay, COLA, and discretionary bonuses unless included by employment contract or CBA.

Takeaway: Under PD 851, Gross 13th Month equals Total Basic Earned ÷ 12 (₱140,700). The first ₱90k is tax-free, and only the ₱50.7k excess is subject to BIR graduated tax in December payroll.
How 13th Month Pay and the ₱90,000 Tax Exemption Work
A common point of confusion is whether 13th month pay is capped at ₱90,000. Under Presidential Decree No. 851, there is NO cap on the gross 13th month pay you can earn—it is always equal to 1/12th of your total basic salary earned during the calendar year.
The ₱90,000 limit is strictly a tax-exemption threshold established by the TRAIN Law (RA 10963). If your 13th month pay is ₱140,700, the first ₱90,000 is completely tax-free. Only the remaining ₱50,700 is treated as taxable compensation in your December annualized withholding tax.
Who is entitled to 13th Month Pay?
All rank-and-file employees in the private sector who have worked for at least one (1) month during a calendar year are legally entitled to receive 13th month pay, regardless of their employment status (regular, probationary, contractual, or seasonal).
Resigned or separated employees must receive their pro-rated 13th month pay as part of their final pay within 30 days of separation.
Questions people ask next
Is 13th month pay capped at ₱90,000?
No. There is no legal cap on the gross 13th month pay amount. An employee with a ₱140,700 salary is entitled to the full ₱140,700 gross 13th month pay. The ₱90,000 cap is solely the maximum tax-exempt limit under the TRAIN Law.
How is the tax on the portion above ₱90,000 calculated?
The taxable excess above ₱90,000 is added to your taxable income and taxed at your marginal BIR tax rate (e.g., 20%, 25%, 30%, or 35%) during year-end tax annualization.
Is 13th month pay the same as Christmas bonus?
No. 13th month pay is a mandatory statutory benefit required by law (PD 851). A Christmas bonus is discretionary unless made mandatory through a contract or collective bargaining agreement.
