Step-by-step calculation algorithm
Calculations follow the standard statutory sequence:
// 1) Employee social contributions
emp_social = gross * (emp_pension + emp_disability + emp_sickness) / 100
// 2) Health insurance basis and contribution
health_base = max(0, gross - emp_social)
health = health_base * (health_rate / 100)
// 3) Tax base
tax_base = max(0, gross - emp_social - deductible_costs)
// 4) Advance income tax
tax = max(0, tax_base * (tax_rate / 100) - tax_free_allowance)
// 5) Net take-home pay
net = gross - emp_social - health - tax
// 6) Total employer cost
er_social = gross * (er_pension + er_disability + er_accident + er_labour_fund + er_fgsp) / 100
total_employer_cost = gross + er_social
// 7) Annualized summary
if period == 'year': multiply monthly values by 12
