# Create calculator instance
calculator = MonacoPayslipCalculator(
    gross_salary=3500.00,
    employee_type='standard'
)

# Calculate contributions
result = calculator.calculate()

# Display results
print(f"Gross Salary: €{result['gross_salary']:.2f}")
print(f"Employee Contributions: €{result['employee_total']:.2f}")
print(f"Net Salary: €{result['net_salary']:.2f}")
print(f"Employer Contributions: €{result['employer_total']:.2f}")

Standard Contribution Structure

Monaco payslip calculations follow this structure:

├─ Employee Contributions (Cotisations Salariales)
│  ├─ Health Insurance (Maladie)
│  ├─ Pension (Vieillesse)
│  ├─ Unemployment (Chômage)
