13th Month Pay Calculator

The simplest mandatory benefit formula in the region

Under Presidential Decree No. 851, every rank-and-file employee in the private sector is entitled to 13th month pay — a genuinely simple calculation: total basic salary earned during the calendar year, divided by 12. No multipliers, no tenure tiers, no minimum service requirement beyond having worked at least one month in the year.

For an employee earning a steady ₱25,000 a month across a full year, that's ₱25,000 — effectively one month's extra pay. For someone who started mid-year or had unpaid leave, the total basic salary actually earned is what gets divided by 12, so the payout scales down proportionally.

What counts as "basic salary"

This is where most miscalculations happen. Basic salary means your regular monthly pay — it does not include:

• Overtime pay
• Holiday premium pay
• Night shift differential
• Cost-of-living allowances and other allowances (unless your company practice or collective bargaining agreement explicitly includes them)

Paid leave actually taken during the year (sick leave, vacation leave, service incentive leave) generally does count, since you were still earning your basic salary during that time — it's unpaid absences that reduce the total.

Who's entitled to it

Every rank-and-file employee in the private sector — regular, probationary, or casual — who has worked at least one month during the calendar year. Managerial employees are excluded by the strict legal definition, though many companies extend the benefit anyway as policy. DOLE makes no exemptions for employers citing financial hardship; this is a mandatory benefit with a hard December 24 payment deadline every year.

FAQ

Is 13th month pay taxable?

It's tax-exempt up to ₱90,000 per year, combined with any other bonuses and benefits. Only the amount above that ceiling is subject to withholding tax.

What if I took maternity leave this year?

The period covered by SSS maternity benefit isn't counted as basic salary earned from your employer, so it doesn't contribute to your 13th month pay calculation — your payout will be smaller in a year that included maternity leave.

What happens if my employer doesn't pay by December 24?

You can file a complaint with your nearest DOLE field office — this is a strictly enforced statutory deadline with no exemptions.
