13th Month Pay Calculator

What you are legally owed under Philippine law, including how a partial year, unpaid leave and excluded pay components change the final figure.

Advanced: other bonuses / other income (affects tax on any amount over ₱90,000)

Leave at ₱0 if you're not sure — the tax estimate on any amount over ₱90,000 will then assume no other income, which UNDERSTATES the real tax if you do have other taxable income this year.

Frequently asked questions

How is 13th month pay calculated?
Total basic salary earned during the calendar year divided by twelve. Only basic salary counts — overtime, holiday premiums, night differential, allowances and most bonuses are excluded unless your employer treats them as part of basic pay by policy.
Do I get 13th month pay if I resigned mid-year?
Yes, prorated. If you worked any part of the year you are entitled to a proportionate share based on the basic salary you actually earned before leaving, and it should be paid on or before separation or with the December run.
Does unpaid leave reduce it?
Yes, indirectly. The calculation is based on basic salary actually earned, so periods of unpaid leave lower the total earned and therefore lower the 13th month figure. Paid leave does not.
Is 13th month pay the same as a Christmas bonus?
No. 13th month pay is a legal entitlement for rank-and-file employees with a statutory formula and deadline. A Christmas bonus is discretionary — an employer can change or withdraw it, and it does not substitute for the 13th month obligation.
