Subject:    Computation of 13th month at HAMP

Kindly recompute the 13th month at HAMP to see if this was in conformity with the example below:

Computation of 13th month steps

1. Computation

These are the steps on how to compute for the 13th month pay.

The following are the assumptions:

1) The employee's daily wage rate is Php1,000.00;

2) The workweek is 6 days a week; and

3)There is one rest day per week.

a. Complete basic salary earned in a year

If covered employees have complete attendance in a year, then their 13th month pay is computed as follows:

Months	Workdays	Services Rendered	Basic Salary Earned (Php)
January	27	Complete attendance	27,000.00
February	24	Complete attendance	24,000.00
March	26	Complete attendance	26,000.00
April	26	Complete attendance	26,000.00
May	26	Complete attendance	26,000.00
June	26	Complete attendance	26,000.00
July	27	Complete attendance	27,000.00
August	27	Complete attendance	27,000.00
September	26	Complete attendance	26,000.00
October	26	Complete attendance	26,000.00
November	26	Complete attendance	26,000.00
December	26	Complete attendance	26,000.00
Total Basic Salary Earned in a Year			314,000.00

Formula:

Total basic salary earned during the year / 12 months = proportionate 13th mo. pay

Sample computation:

Php314,000.00 / 12 = Php26,166.17

b. Incomplete basic salary earned in a year

If covered employees have incomplete attendance in a year, then their 13th month pay is computed as follows:

Months	Workdays	Services Rendered	Basic Salary Earned (Php)
January	27	Complete attendance	27,000.00
February	24	1 day absence	23,000.00
March	26	Complete attendance	26,000.00
April	26	Complete attendance	26,000.00
May	26	2 days absence	24,000.00
June	26	Complete attendance	26,000.00
July	27	Complete attendance	27,000.00
August	27	1 day leave with pay	26,000.00
September	26	Complete attendance	26,000.00
October	26	Complete attendance	26,000.00
November	26	2 days leave with pay	24,000.00
December	26	Complete attendance	26,000.00
Total Basic Salary Earned in a Year			307,000.00

Formula:

Total basic salary earned during the year / 12 months = proportionate 13th mo. pay

Sample computation:

Php307,000.00 / 12 = Php25,583.33

Basic salary is defined as 'all remunerations or earnings paid by an employer to an employee for services rendered.' (Rules and Regulations Implementing P.D. 851, Section 2(b). The key words in the definition are "for services rendered."

Thus, during absences, the employee does not earn any salary. In the above example, the employee could have earned Php24,000.00 in February because there were 24 workdays. However, due to a 1-day absence, the employee was only able to earn Php23,000.00. The same goes for the month of May wherein the employee had 2 absences and thus was only able to earn Php26,000.00.

As for leave with pay, the employee may have received pay for the day of absence because of a leave credit, and not for services rendered. Thus, by definition, the amount paid to the employee is not part of basic salary earned. To be clear, the employee did not perform any service or rendered work to be entitled to the pay during the leave with pay, which is a requirement for basic salary earned.
