About 13th Month Pay Calculator (Philippines)
13th month pay is a statutory right in the Philippines under Presidential Decree 851 — every rank-and-file employee who worked at least one month in the calendar year must receive it, due on or before December 24. The formula is deliberately simple: total BASIC salary actually earned during the year, divided by 12. A full year at ₱20,000 basic yields exactly ₱20,000; six months yields ₱10,000 — proration is automatic because the numerator only counts what you earned. The two classic disputes are both about the numerator. First, 'basic' excludes allowances (COLA, transport), overtime, holiday premiums and night differentials — a payslip heavy on allowances produces a smaller 13th month than the headline pay suggests. Second, unpaid absences and LOP months shrink the total earned and therefore the payout; maternity leave benefits paid by SSS are not 'earned basic salary' from the employer, a nuance that surprises many on return. Tax draws one line: 13th month pay plus 'other benefits' (Christmas bonus, productivity incentives) are exempt up to ₱90,000 combined per year; the excess is ordinary taxable compensation. Note what 13th month is NOT: a Christmas bonus (that's gratuitous and on top, if the employer gives one), and not optional for struggling employers — only narrowly-exempt categories (e.g., government, purely commission-paid workers, kasambahay covered by a different law) sit outside PD 851's reach.

Frequently asked questions
I resigned in August — do I still get 13th month pay?+
Yes — resigned, terminated or end-of-contract employees are entitled to a PRORATED 13th month based on basic salary actually earned during the calendar year before leaving, normally released with your final pay. Working January through August at ₱20,000 earns ₱160,000 basic → ₱13,333. Employers who pay it only to December-roster employees are violating PD 851; DOLE handles such complaints routinely.
Is the 13th month the same as a Christmas bonus?+
No — and the difference is enforceable. The 13th month is a statutory OBLIGATION with a fixed formula and a December 24 deadline; a Christmas bonus is a voluntary gratuity on top, in whatever amount the employer chooses (though a bonus given consistently for years can ripen into company practice that's hard to withdraw). If you receive both, both count together against the ₱90,000 tax exemption ceiling.
Are allowances and overtime included in the computation?+
No. PD 851's base is BASIC salary only: COLA, transport/meal allowances, overtime pay, premium pay, night shift differential and monetized leave are all excluded by the implementing rules. The practical effect: two employees with identical take-home can receive different 13th month amounts if one's package is allowance-heavy. Check your payslip's basic line — that times months worked, over 12, is the law's whole formula.
When exactly must it be paid, and can it be split?+
The deadline is on or before December 24, and yes — employers may pay half mid-year (commonly with June schooling expenses) and the balance in December; the law fixes the total and the final deadline, not the schedule. Non-payment or underpayment is a labor-standards violation: document your basic salary and months worked, raise it with HR first, then DOLE's regional office if unresolved.
