How 13th month pay is computed
Under PD 851, 13th month pay is one-twelfth of the basic salary you earned during the calendar year. For a fixed monthly basic salary, that works out to your monthly basic salary multiplied by the months worked, divided by 12.
If you worked the full year, the result usually equals one month's basic salary. If you worked only part of the year, the amount is prorated based on the basic salary actually earned during the months counted.

Prorated estimate
For employees who worked part of the year. Based on basic salary earned during the months counted.
₱24,000 × 6 ÷ 12 = ₱12,000
