13th month pay for ₱18,000 monthly salary

How much you get, how to pro-rate it, and whether any of it is taxed — with a worked example.

ESTIMATE

Guide and estimates as of 3 November 2026, for information only — not legal or tax advice. Rules: PD 851 and its 1987 Revised Guidelines, DOLE Labor Advisory No. 16, Series of 2025 (issued late November 2025), the ₱90,000 exemption under RA 10963 (TRAIN). The 2026 DOLE advisory had not been published when this was written; the rules have been the same every year.

If you earn ₱18,000 a month and worked the whole of 2026, your 13th month pay is ₱18,000 — exactly one month of basic salary. Joined in March? Then it's ₱15,000. Here's how that works, plus tables for every start month.

How it plays out for one employee

Maria earns ₱18,000 a month as an admin assistant at a logistics company in Quezon City. She started on 1 March 2026. On some payslips her gross pay looks bigger — ₱19,400 in August, because of overtime during inventory week, and ₱18,900 in November with holiday pay for 1 November.

None of those extras count. The 13th month is based on basic salary only, so her computation is 10 months × ₱18,000 = ₱180,000, divided by 12 = ₱15,000. If her company had promised (in her contract or by long practice) to include overtime, it would have to honour that — but the legal minimum ignores it.

Why your payslip total is the wrong number to use

Labour advisories define basic salary as all pay for services rendered, but they exclude overtime, premium pay, night shift differential, holiday pay, cost-of-living allowance and the cash conversion of unused leave. A common mistake is taking the year-to-date “gross” from the December payslip and dividing it by 12. For Maria, that would overstate her 13th month by a few hundred pesos — and when your employer pays the correct (smaller) amount, it looks like underpayment when it isn't.

The reverse also happens: if your company deducted unpaid absences, your basic salary for the year is lower than 10 × ₱18,000. Use the amount actually earned, not the rate on your contract.

Tax-free room for other bonuses

13th month pay of ₱18,000 plus a ₱10,000 bonus compared with the ₱90,000 tax-free ceiling: ₱62,000 of room left₱90,000 tax-free ceilingTotal ₱28,000 — ₱62,000 of tax-free room left13th monthChristmas bonus (example)
The ceiling covers the 13th month and other benefits combined, per taxpayer per year (NIRC Sec. 32(B)(7)(e), as amended by TRAIN).

A full-year 13th month of ₱18,000 is entirely exempt. You still have ₱72,000 of tax-free room for a Christmas bonus, productivity incentive or other benefits paid in 2026. A ₱10,000 Christmas bonus would still leave ₱62,000 of room.

The 13th month is never subject to SSS, PhilHealth or Pag-IBIG contributions. Tax estimates assume a full year at ₱18,000 with employee contributions of about ₱1,550 a month deducted.

Leave without pay: the effect in pesos

Paid leave doesn't reduce anything. Unpaid days, undertime and tardiness deductions do — but only by a twelfth of the amount deducted.

Before you check your December payslip

If your contract says “₱18,000 inclusive of allowance”, ask HR for the split. Only the basic part counts for the 13th month.
Don't confuse the 13th month with a Christmas bonus. The 13th month is mandatory; a Christmas bonus is voluntary unless it's in your contract or has become a company practice.
Keep the employer's computation. If you were paid less than one-twelfth of your basic salary for the year, a written query to HR settles most cases before DOLE is needed.

FAQ

I earn ₱18,000 and started in March. How much is my 13th month pay?

About ₱15,000: 10 months × ₱18,000 = ₱180,000 of basic salary, divided by 12. Unpaid absences would reduce it slightly.

Does overtime pay increase my 13th month?

Not under the legal minimum. Overtime, holiday and premium pay, night differential and COLA are excluded unless your contract, CBA or company practice treats them as part of basic salary.

Do I need to work a minimum period to get it?

Yes — at least one month during the calendar year. Below that, there is no entitlement under PD 851.

How is 13th month pay computed on a ₱18,000 salary?

Add up the basic salary you earned from January to December and divide by 12. For a full year at ₱18,000 that gives ₱18,000; each month worked adds ₱1,500.
