Chapter 42: Fast Formula for Gross to Net Pay Calculation

Key Components:

1. Gross Earnings: Basic, HRA, bonuses, allowances

2. Statutory Deductions: Tax, Provident Fund (PF), ESI, etc.

3. Voluntary Deductions: Loan EMI, insurance premiums

4. Net Pay: Gross Earnings – Total Deductions

Sample Gross to Net Formula:

DEFAULT FOR BASIC_PAY IS 0
DEFAULT FOR HRA IS 0
DEFAULT FOR BONUS IS 0
DEFAULT FOR PF IS 0
DEFAULT FOR TAX IS 0
DEFAULT FOR INSURANCE_DED IS 0
DEFAULT FOR LOAN_EMI IS 0

INPUTS ARE BASIC_PAY, HRA, BONUS, PF, TAX, INSURANCE_DED, LOAN_EMI

GROSS = BASIC_PAY + HRA + BONUS
DEDUCTIONS = PF + TAX + INSURANCE_DED + LOAN_EMI
NET_PAY = GROSS - DEDUCTIONS

RETURN NET_PAY
