About this tool
Add income and expense items with labels and amounts. Expenses are tagged with a category: Housing, Food, Transport, Entertainment, or Other. A live summary shows total income, total expenses, and net balance — highlighted green when positive and red when negative. An SVG pie chart breaks down expenses by category at a glance. All data is saved automatically to localStorage so your budget persists across visits. Export to CSV or clear everything with a single click.
