Expense Tracker

Most expense trackers want your email, your bank login, or a monthly subscription. This one runs entirely in your browser. Add expenses, see category breakdowns, track monthly totals — and export to CSV whenever you want a backup. Your financial data never leaves your device.

Why Track Expenses?

People who track spending save 10-15% more on average, according to financial behavior research. The act of recording an expense creates awareness — you start noticing patterns, catching subscriptions you forgot about, and making more intentional choices. It's the single highest-impact personal finance habit you can build.

The 30-Day Tracking Challenge

Track every single expense for 30 days. Don't change your behavior — just record. At the end of the month, review the category breakdown. Most people find at least one category where they're spending 2-3x what they expected. That awareness alone often leads to lasting changes without any budgeting rules or restrictions.

How This Tool Works

Add expenses with a date, amount, category, and optional description. Data saves automatically to your browser's localStorage. Navigate between months to see spending history. The category breakdown shows where your money goes at a glance. Export to CSV for spreadsheet analysis or backup. Clear individual entries or entire months as needed.
