Calculate Employee Salary with Python

Salary calculation is a critical aspect of payroll management. Python makes it easy to compute salaries by including basic pay, allowances, deductions, and bonuses. This tutorial walks you through the steps to calculate day-wise salary components and generate a detailed payslip using Python.

1. Components of Salary

• Basic Pay: The base salary of the employee.
• DA (Dearness Allowance): Calculated as 20% of the basic pay.
• HRA (House Rent Allowance): Calculated as 15% of the basic pay.
• Vehicle Allowance: ₹200 per day worked.
• Medical Allowance: Fixed at ₹1,000 per month.
• Bonus: 10% of the basic pay, applicable for full attendance only.
• PF Deduction: 12% of the basic pay.
• Professional Tax: Fixed at ₹200 per month.

2. Python Code for Salary Calculation

# Inputs
basic_pay = float(input("Enter Basic Pay: ₹"))
days_present = int(input("Enter Number of Days Present: "))

# Constants
full_attendance_days = 30  # Total days in a month (modifiable)
da_percentage = 0.20       # DA as 20% of Basic Pay
hra_percentage = 0.15      # HRA as 15% of Basic Pay
daily_vehicle_allowance = 200  # Daily vehicle allowance
medical_allowance = 1000       # Fixed monthly medical allowance
pf_percentage = 0.12           # PF as 12% of Basic Pay
professional_tax = 200         # Fixed professional tax per month
bonus_percentage = 0.10        # Bonus as 10% of Basic Pay (only for full attendance)

# Day-wise Components
daily_basic = basic_pay / full_attendance_days
daily_da = (basic_pay * da_percentage) / full_attendance_days
daily_hra = (basic_pay * hra_percentage) / full_attendance_days

# Components Based on Days Present
total_basic = daily_basic * days_present
total_da = daily_da * days_present
total_hra = daily_hra * days_present
total_vehicle_allowance = daily_vehicle_allowance * days_present

# Fixed Components
total_medical_allowance = medical_allowance
total_pf = basic_pay * pf_percentage
total_bonus = basic_pay * bonus_percentage if days_present == full_attendance_days else 0

# Deductions
total_deductions = total_pf + professional_tax

# Final Salary Calculation
gross_salary = total_basic + total_da + total_hra + total_vehicle_allowance + total_medical_allowance + total_bonus
net_salary = gross_salary - total_deductions

# Generate Payslip
print("\n--- Payslip Breakdown ---")
print(f"Basic Pay: ₹{total_basic:.2f}")
print(f"DA (20% of Basic Pay): ₹{total_da:.2f}")
print(f"HRA (15% of Basic Pay): ₹{total_hra:.2f}")
print(f"Vehicle Allowance: ₹{total_vehicle_allowance:.2f}")
print(f"Medical Allowance: ₹{total_medical_allowance:.2f}")
print(f"Bonus: ₹{total_bonus:.2f}")
print(f"Gross Salary: ₹{gross_salary:.2f}")
print(f"Deductions: ₹{total_deductions:.2f}")
print(f"Net Salary: ₹{net_salary:.2f}")

3. Sample Input and Output

Input:

Enter Basic Pay: ₹30000
Enter Number of Days Present: 30

Output:

--- Payslip Breakdown ---
Basic Pay: ₹30000.00
DA (20% of Basic Pay): ₹6000.00
HRA (15% of Basic Pay): ₹4500.00
Vehicle Allowance: ₹6000.00
Medical Allowance: ₹1000.00
Bonus: ₹3000.00
Gross Salary: ₹50500.00
Deductions: ₹3800.00
Net Salary: ₹46700.00

Conclusion

With Python, salary calculations become straightforward and customizable. This script provides a complete breakdown of salary components, including basic pay, allowances, deductions, and bonuses, ensuring a professional payslip generation.
