When your life circumstances change (for example, if you become a parent), it is usually more efficient to add all the categories from the appropriate list. Your reports show the subcategory amounts as subtotals for their parent category. For example, you can create subcategories under the Recreation category to track how much you spend on specific activities.
Choose New Category, which is located at the upper right of the Category List window.From the Quicken Tools menu, choose Category List.
