Personal Finance Tracker

Simple Personal Finance Tracker in Python

First, make sure you have Python installed on your system. You can use any text editor or IDE to write your code.

Code

import json

class FinanceTracker:
    def __init__(self, filename='finance_data.json'):
        self.filename = filename
        self.load_data()

    def load_data(self):
        try:
            with open(self.filename, 'r') as f:
                self.data = json.load(f)
        except FileNotFoundError:
            self.data = {'income': 0, 'expenses': [], 'balance': 0}

    def save_data(self):
        with open(self.filename, 'w') as f:
            json.dump(self.data, f)

    def add_income(self, amount):
        self.data['income'] += amount
        self.update_balance()
        self.save_data()

    def add_expense(self, amount, description):
        self.data['expenses'].append({'amount': amount, 'description': description})
        self.update_balance()
        self.save_data()

    def update_balance(self):
        total_expenses = sum(expense['amount'] for expense in self.data['expenses'])
        self.data['balance'] = self.data['income'] - total_expenses

    def view_summary(self):
        print(f"Total Income: ${self.data['income']}")
        print("Expenses:")
        for expense in self.data['expenses']:
            print(f" - ${expense['amount']} for {expense['description']}")
        print(f"Balance: ${self.data['balance']}")

def main():
    tracker = FinanceTracker()

    while True:
        print("\nPersonal Finance Tracker")
        print("1. Add Income")
        print("2. Add Expense")
        print("3. View Summary")
        print("4. Exit")
        
        choice = input("Select an option: ")

        if choice == '1':
            amount = float(input("Enter income amount: "))
            tracker.add_income(amount)
        elif choice == '2':
            amount = float(input("Enter expense amount: "))
            description = input("Enter expense description: ")
            tracker.add_expense(amount, description)
        elif choice == '3':
            tracker.view_summary()
        elif choice == '4':
            break
        else:
            print("Invalid choice. Please try again.")

if __name__ == "__main__":
    main()
