Budget Tracker

What the Budget Tracker Does

The Budget Tracker is a private, browser based tool for logging income and expenses and watching your balance in real time. Add a transaction with a description, amount, type, category, and date, and the summary cards update instantly with total income, total expenses, and the remaining balance. A category breakdown shows where the money went, and a month filter lets you review any period in seconds.

Every entry is saved to your browser's local storage, so your data survives page refreshes and stays on your device. Nothing is uploaded, no account is needed, and the tracker works offline once the page has loaded.

How to Use the Budget Tracker

1. Enter a description and amount for the transaction, such as "Grocery shopping" and 64.20.
2. Choose whether it is an expense or income. The category selector switches to Income automatically for income entries.
3. Pick a category and confirm the date, then press Add transaction.
4. Watch the Summary cards and Category breakdown update immediately on the right.
5. Use Filter by month to review a single month, or leave it on All months for the full picture.

Reading the Summary Cards

• Income: the total of every income entry in the selected period.
• Expenses: the total of every expense entry in the selected period.
• Balance: income minus expenses. A negative balance is shown in red so overspending is impossible to miss.

Because the summary respects the month filter, you can compare months at a glance: switch between them and the income, expense, and balance figures recalculate instantly.

Expense Categories and the Breakdown

Each expense is assigned to a category: Food, Transport, Housing, Entertainment, Shopping, Health, Education, or Other. The category breakdown aggregates expenses for the selected period and shows each category's share of total spending as an amount and a percentage, with a proportional bar for quick visual comparison. If housing eats 45 percent of your spending, the bar makes that obvious immediately.

Income entries are tracked under a single Income category so the breakdown always reflects spending only. If you want a deeper analysis of a monthly plan, the Budget Calculator and the 50-30-20 Rule Budget Calculator pair well with this tracker.

Your Data Stays in Your Browser

Financial entries are sensitive, so the tracker never sends them anywhere. All processing happens in your browser and everything is stored in local storage under a single key. Clearing your browser's site data removes the entries, and because storage is local, the data does not sync between devices or browsers. Use Clear all inside the Transactions panel to wipe everything at once, or delete individual entries with the trash button on each row.

Tips for Building a Tracking Habit

• Log transactions the same day they happen, while the amount is fresh in your memory.
• Write descriptions you will understand in a month, for example "Train pass" instead of "Transport".
• Check the month filter at the end of each month and compare the balance to the previous one.
• Watch the category breakdown to spot the category that deserves a budget cap.
• Keep income entries consistent so monthly comparisons stay meaningful.
