About this household expense tracker
The household expense tracker lets you log every household transaction for a chosen month, measure them against a monthly budget, and get an instant per-category breakdown — all without an account or internet connection.
The tool filters your transaction list to only the entries whose date falls inside the selected month. It then sums amounts across ten fixed categories — Housing, Utilities, Groceries, Transport, Dining, Entertainment, Health, Personal, Savings, and Other — and divides each category total by total spend to produce a percentage share. Budget utilisation is calculated as (total spent ÷ monthly budget) × 100. Transactions from other months are kept in your browser's localStorage but are excluded from the current-month totals. The tool is currency-neutral: it formats numbers with your browser's locale separators and displays no currency symbol, so it works for any currency.
Worked example: set month to May 2026, budget to 3 000. Add rent 1 200 (Housing), groceries 480 (Groceries), electricity 95 (Utilities), and a streaming service 16 (Entertainment). Total spent = 1 200 + 480 + 95 + 16 = 1 791; remaining = 3 000 − 1 791 = 1 209; budget used = 59.7 %. In the category breakdown, Housing leads at 67.0 % of total spend (1 200 ÷ 1 791), followed by Groceries at 26.8 %.
This tool suits households, flatmates, or individuals who want a lightweight monthly snapshot of their spending without connecting to a bank or a subscription service.
FAQ
- What is the household expense tracker and how does it calculate totals?
- It is a browser-based tool for logging and summarising monthly household spending. It sums every transaction whose date falls in the selected month, then divides each category subtotal by the total spend to show a percentage share.
- Can I add custom categories?
- No. The tool uses a fixed set of ten categories — Housing, Utilities, Groceries, Transport, Dining, Entertainment, Health, Personal, Savings, and Other. The fixed list keeps reports consistent and comparable across months.
- What currency does the tool use?
- The tool is currency-neutral. It formats numbers using your browser's locale separators but shows no currency symbol, so you can use it for any currency — just enter amounts in your local unit.
- What happens to transactions from other months?
- They are kept in browser localStorage and remain visible in the table (shown faded), but they are excluded from the current-month totals and the Summarize month result. Switch the Month field to their month to include them in a summary.
- Does the tracker store my data on a server?
- No. All data is saved in your browser's localStorage only. Nothing is sent to a server. Clearing site data, switching browsers, or using private/incognito mode will remove the stored transactions.
- Is the household expense tracker free to use?
- Yes, it is completely free with no account or signup required.
