Expense Tracker

How the expense tracker works – Every expense you enter is stored in your browser's local storage. The app calculates totals, category summaries, and trends in real time. The core formulas are simple:

• Total expenses = sum of all expense amounts.
• Category total = sum of amounts for a given category.
• Monthly total = sum of expenses where date falls in current month.
• Weekly trend = daily sums for the last 7 days.

All amounts are displayed with the currency symbol you choose – no conversion is applied; the symbol is purely cosmetic.

🔍 Why track expenses?

Regular expense tracking helps you:

• Identify wasteful spending and adjust habits.
• Build a realistic monthly budget.
• Save for goals like an emergency fund or vacation.
• Avoid credit card debt by staying within limits.

📊 Interpreting the charts

The category doughnut chart shows the proportion of your total spending by category. Large slices indicate where most of your money goes. The weekly bar chart reveals spending patterns across days – you might notice higher spending on weekends.

💡 Budgeting tips

• Follow the 50/30/20 rule: 50% for needs, 30% for wants, 20% for savings/debt.
• Review your category totals each month and set limits (e.g., ₹10,000 for dining).
• Use the filters to see specific time periods and spot trends.
• Keep your expense descriptions clear so you can later analyse them.
