Free Budget Tracker Web App with Login – Google Sheets

A personal budget tracker with a real login behind it. Users sign up, record income and expenses by category, attach the receipt, and watch the charts move. Google Sheets stores everything, so the data stays yours and stays readable.

More than a list of numbers

Entering transactions is the easy part; seeing the shape of your spending is the point. The dashboard puts income against expense with doughnut and bar charts driven by Chart.js, so categories that are quietly eating the month become obvious rather than something you work out at the end of it.

Receipts attached

Expenses can carry a receipt image uploaded to Google Drive and linked to the row. For anyone who needs to justify a claim later — or just remember what a payment actually was — the evidence sits with the entry instead of in a shoebox.

Accounts and categories

Login and signup are included with accounts stored in the sheet, and each user manages their own profile. Budgets are organised by category, so the same build works for a household splitting expenses or an individual tracking their own.

Who it suits

Anyone tracking personal or household finances, freelancers separating business from personal spend, and developers who want a complete Apps Script project with authentication, file upload and charting in one place.

Setup

Copy the sheet, deploy the script, sign up and start entering. The Materialize CSS interface is mobile responsive for entering an expense on the spot. The video covers the full build, and support is free if you get stuck.
