How to Set Up a Simple Automated Budget Tracker in Google Sheets

Start by creating a new Google Sheet and setting up two distinct tabs. Name the first tab Transactions and the second tab Summary. This separation ensures that your raw data entry does not clutter your final financial overview.

In the Transactions tab, create headers for Date, Description, Category, and Amount. To maintain consistency, use the Data Validation tool on the Category column to create a dropdown menu. This prevents typos from interfering with your calculations later on.

Move to the Summary tab and list your budget categories in the first column. In the second column, enter the monthly budget amount you have allocated for each category. Leave a third column open to display the actual spending totals.

To automate the tracking, use the SUMIF function in the actual spending column. Write a formula that scans the Category column in the Transactions tab and sums all amounts associated with the specific category listed in that row of your Summary tab.

Enhance your tracker by applying conditional formatting to the summary totals. Set a rule that changes the cell color to red whenever the actual spending exceeds the planned budget. This provides an immediate visual warning when you are overspending.

To keep the system working, consistently log every expense in the Transactions tab as they occur. Because the Summary tab updates automatically, you will always have a real-time view of your financial health without manual recalculations.
