How Simplify Budget works
Set your fixed expenses
Set up your income and fixed expenses at the beginning of the month to see how much is available to spend. Fixed payments auto-fill every month after you set them once.
Set spending goals
Set up spending goals for each expense category and keep an eye on your progress throughout the month to stay on target.
Track daily expenses
Enter daily expenses in the calendar as you spend. Quickly log purchases from your phone so everything stays up to date.
Track your net worth
Net worth tracking is essential to grow your wealth. Each month enter all your assets and liabilities to make better long-term money decisions.
How Your Data Stays Private
Simplify Budget is a Google App that creates a single Google Sheet in your Drive to write and update all transactions—only that sheet, nothing else in your Google account.
Google Security Review Verified
The app is verified by Google's OAuth security review process, confirming it only requests the permissions needed to function. Google has reviewed our security practices and data handling.
Why did we build it this way?
Spreadsheets alone are limiting. Dedicated mobile apps lock you to specific devices and 3rd party databases. Our solution: Google Apps Script that works with a Google Sheet gives you the best of both: work from any device with a browser, share budgets with family, and own your data forever.
Simplify Budget is free forever

Simplify Budget is free forever. There are no subscriptions or license fees. If you find the app helpful, you can optionally leave a tip to support development.
Simplify Budget needs permission to create ONE Google Sheet in your Drive and read/write to that sheet only. It cannot access anything else - not your emails, not your other files, nothing. Your financial data stays 100% private in your own Google account. This limited permission model is actually a security feature that protects your privacy.
Your data stays in your Google Drive (not our servers), it's free forever (not a subscription), has a Monthly Expense Calendar for faster expense entry, and is perfect for families since multiple people can use the same budget.
Open the app, go to settings, and click 'New Database'. It automatically creates a new Google Sheet in your Drive and links it. That's it - you're ready to start tracking. Takes 30 seconds.
Yes! Since your data lives in Google Sheets, anyone you share the sheet with can use the same budget in Simplify Budget. Perfect for couples, families, or business partners who want to track expenses together.
Your financial data stays in your Google Sheets forever. Since we don't store your data on our servers, you can stop using the app anytime and still access all your financial history in Google Sheets.
Imagine a calendar where days are rows and your spending categories (food, gas, shopping) are columns. To track an expense, just tap where the day meets the category - like Monday + Food = $12 lunch. You see your whole month's spending at once.
Yes! Simplify Budget is fully mobile optimized. Most users add expenses on their phone throughout the day since it's so quick and visual. The app works perfectly on phones, tablets, and desktop.
Set up each recurring payment once with its amount, frequency (monthly/quarterly/yearly), and end date. Simplify Budget automatically generates future payments and shows them in your Monthly Expense Calendar and budget. No end date? It keeps creating payments for the next cycle.
You can rename, reorder, and hide/show any of the 30 categories. We don't allow deleting categories to preserve your historical data - if you had expenses in a category you no longer use, they'll still appear in your reports.
Your financial data never touches our servers - it only exists in your Google Drive. We literally cannot see your transactions, balances, or spending patterns. Since your data stays in your own Google account, you maintain full control and ownership.
Simplify Budget supports all major currencies. You can set your preferred currency in the settings, and all calculations and displays will use your chosen currency format.
Yes! Simplify Budget has passed Google's OAuth verification process for Google Apps Script applications. This means Google has reviewed our app for security and privacy compliance, and users see a 'verified' badge instead of security warnings when granting permissions. The verification covers our privacy policy, data handling practices, and ensures we follow Google's security standards. Your data is protected by Google's security infrastructure and never leaves your Google account.
