Step-by-Step Computation Examples
🧾 Example 1: Full-Year Employee
Monthly Salary: ₱20,000
Worked: January to December (12 months)
Step 1: Compute total basic salary
₱20,000 × 12 = ₱240,000
Step 2: Divide by 12
₱240,000 ÷ 12 = ₱20,000
✅ 13th Month Pay = ₱20,000
🧾 Example 2: Employee Hired Mid-Year
Monthly Salary: ₱18,000
Hired: July (worked 6 months)
Step 1: Total salary
₱18,000 × 6 = ₱108,000
Step 2: Divide by 12
₱108,000 ÷ 12 = ₱9,000
✅ 13th Month Pay = ₱9,000
🧾 Example 3: Employee with Absences (Unpaid Leave)
Monthly Salary: ₱15,000
Total earned (after deductions): ₱150,000
Step 1: Divide by 12
₱150,000 ÷ 12 = ₱12,500
