13th Month Pay Calculator
DOLE
One twelfth of the basic salary actually earned in the calendar year, pro-rated for an incomplete year and net of unpaid absences.
This calculator does not carry current agency interest or dividend rates. You enter the rate, so a result is only as current as the figure you typed.
It is an estimate for planning, not an official quotation, and DOLE's own computation is what governs. Confirm the figures before you commit to anything.
Every figure on this page is from Department of Labor and Employment's own published documents.

What this calculator does
PD 851 sets the minimum at one twelfth (1/12) of the total basic salary earned within a calendar year. Two words decide most disputes: basic and earned.
| Monthly basic | Months worked | Basic earned | 13th month pay |
|---|---|---|---|
| ₱24,000.00 | 12 | ₱288,000.00 | ₱24,000.00 |
| ₱24,000.00 | 6 | ₱144,000.00 | ₱12,000.00 |
| ₱18,000.00 | 12 | ₱216,000.00 | ₱18,000.00 |
| ₱15,000.00 | 3 | ₱45,000.00 | ₱3,750.00 |
A full year at a steady salary produces exactly one month’s pay. That is a consequence of the formula, not the rule itself, which is why an incomplete year does not produce a full month.
What a part year actually pays
| Started work | Months worked | On ₱20,000.00 monthly basic |
|---|---|---|
| 1 January | 12 | ₱20,000.00 |
| 1 April | 9 | ₱15,000.00 |
| 1 July | 6 | ₱10,000.00 |
| 1 October | 3 | ₱5,000.00 |
| 1 December | 1 | ₱1,666.67 |
There is no minimum length of service in the formula itself: 1 month worked earns 1/12 of 1 month’s basic.
Earned, not contracted
Unpaid absences reduce the basic salary earned and therefore the 13th month pay. A ₱12,000.00 monthly salary with ₱12,000.00 of unpaid absence across the year is ₱132,000.00 earned, so ₱11,000.00 rather than ₱12,000.00.
A salary ladder
| Monthly basic | Full year 13th month | Half year |
|---|---|---|
| ₱10,000.00 | ₱10,000.00 | ₱5,000.00 |
| ₱15,000.00 | ₱15,000.00 | ₱7,500.00 |
| ₱20,000.00 | ₱20,000.00 | ₱10,000.00 |
| ₱30,000.00 | ₱30,000.00 | ₱15,000.00 |
| ₱50,000.00 | ₱50,000.00 | ₱25,000.00 |
Basic, not gross
Basic salary excludes allowances and monetary benefits that are not part of the regular basic pay: unused leave conversions, overtime, premium, night differential and holiday pay are all outside it unless company practice has integrated them.
Where it sits among the statutory minimums
| Benefit | Minimum | Basis |
|---|---|---|
| 13th month pay | 1/12 of basic earned in the calendar year | PD 851 |
| Service incentive leave | 5 days a year after 1 year of service | Labor Code Art 95 |
| Paternity leave | 7 days, first 4 deliveries | RA 8187 |
| Holiday pay, regular holiday worked | Twice the regular rate | Labor Code |
The deadline
Payment is due on or before 24 December each year. It is a statutory minimum, so a more generous company practice satisfies it and cannot be used to reduce it. Employers report compliance through the DOLE Online Compliance Portal at reports.dole.gov.ph, which the current advisory sets at not later than 15 January 2026, covering 8 items including total employment and the amount granted per employee.
Coverage, exclusions and the reporting requirement are in our 13th month pay guide. The other DOLE minimums that run alongside it are service incentive leave at 5 days a year and paternity leave at 7 days.
