Expense Tracker
Track your expenses by category, see totals and breakdowns, and understand where your money goes. All data stays in your browser — nothing is sent to any server.
How the Expense Tracker Works
This expense tracker lets you log individual expenses with a date, category, description, and amount. It automatically calculates your total spending, breaks down expenses by category, and shows you where your money is going. All data is stored locally in your browser using localStorage, so your financial information never leaves your device.
Tracking expenses is the foundation of effective budgeting. Research shows that people who actively track their spending save 15-20% more than those who don't. By categorizing expenses, you can identify areas where you're overspending and make informed decisions about where to cut back.

Tips for Effective Expense Tracking
Log expenses immediately after making them to avoid forgetting. Review your spending weekly to stay aware of patterns. Compare your actual spending against your budget categories to identify overruns. Use the category breakdown to find your biggest spending areas — these typically offer the most opportunity for savings. Export your data to CSV for more detailed analysis in spreadsheet software. Consistent tracking over three months reveals reliable spending patterns that you can use to create an accurate budget.
Privacy and Data Storage
All your expense data is stored locally in your browser's localStorage. No data is ever sent to any server, uploaded to the cloud, or shared with anyone. You have complete control over your financial information. Use the export feature to back up your data as a CSV file. Clearing your browser data will remove all stored expenses, so export regularly if you want to keep long-term records.
