COMPUTATIONS
Salary Computation Descriptions Computations Total No. of regular days worked Total No. of regular days worked * rate = Basic Pay Regular Overtime (hours) (Rate/8) * 1.25 (constant) = OT Pay Overtime with Night Differential (Rate/8) * 1. 35 (constant) = OTWND Pay Duty on Day off Rate * 1. 3 = DOD Pay Legal Holidays Rate * 200 % = Legal Holiday Pay Special Holidays Rate * 1.3 % = Special Holiday Pay Gross Pay Basic Pay + OT Pay + OTWND Pay + DOD Pay + Legal Holiday Pay + Special Holiday Pay = Gross Pay SSS Contributions Employee Share (depends on compensation range per month) / 26 (employees regular work days per month) = result * total no. of regular days worked
PhilHealth Contributions Employee Share (depends on compensation range per month) / 26 (employees regular work days per month) = result * total no. of regular days worked Pag-Ibig Contributions Employee Share (depends on compensation range per month) / 26 (employees regular work days per month) = result * total no. of regular days worked Cash Bond Basic Pay * 5% = Cash Bond Admin Fee Basic Pay * 2% = Admin Fee Lates (Rate/8 hours) / 60 minutes = Late Other Deductions Cash Advance + Charges + Loans = Other Deductions Total Deductions SSS co + PhilHealth/Pag-Ibig Contributions + Cash Bond + Admin Fee + Late + Other Deductions = TotalDeductions Net Pay Gross Pay – Total Deductions = Net Pay
13th Month Pay Computation 13th Month Pay Computation Daily rate * 26 regular working days of an employee per month / 313, regular working days of an employee per year = result * total number of days worked by the employee = 13th Month Pay .
