Sample Computations for Different Scenarios
Scenario 1: Full-year Employee
Monthly Basic Salary: ₱25,000
Months Worked: 12
Absences: 0 days
Computation:
(₱25,000 × 12) ÷ 12 = ₱25,000
13th Month Pay: ₱25,000
Scenario 2: Employee with Absences
Monthly Basic Salary: ₱20,000
Months Worked: 12
Absences: 5 days (unpaid)
Computation:
Daily Rate = ₱20,000 ÷ 22 working days = ₱909.09
Deduction = ₱909.09 × 5 = ₱4,545.45
13th Month Pay = (₱20,000 × 12) ÷ 12 – ₱4,545.45 = ₱15,454.55
Scenario 3: Resigned Employee
Monthly Basic Salary: ₱18,000
Date Hired: March 1, 2018
Date Resigned: October 15, 2018
Absences: 2 days
Computation:
Months Worked = 7.5 months (March to mid-October)
Pro-rated Factor = 7.5 ÷ 12 = 0.625
Basic 13th Month = (₱18,000 × 12) ÷ 12 = ₱18,000
Pro-rated Pay = ₱18,000 × 0.625 = ₱11,250
Daily Rate = ₱18,000 ÷ 22 = ₱818.18
Deduction = ₱818.18 × 2 = ₱1,636.36
Final 13th Month Pay: ₱11,250 – ₱1,636.36 = ₱9,613.64
