A system for displaying a spending comparison report includes a spending data repository, a report module, and a display device. The spending data repository is configured to store a current spending amount associated with a current spending group ID and a current spending date, and a historical spending amount associated with a historical spending group ID and a historical spending date. The report module is configured to obtain a spending data grouping selected from multiple spending data groupings, obtain a current date range for the spending data grouping, generate multiple selectable historical date ranges based on the current date range, obtain a historical date range selected from the multiple selectable historical date ranges, retrieve the current spending amount, retrieve the historical spending amount from the spending data repository, and obtain a spending difference between the current spending amount and the historical spending amount. The display device is configured to display the current spending amount, the spending difference, and the historical spending amount.
