Your budget is a list of category groups, each holding categories. You shape that list to match your life — add what you track, rename what does not fit, reorder for priority, and hide what you no longer use. ## Categories and groups A **group** is a heading like Bills, Everyday, or Savings. A **category** is a line you assign money to, like Rent or Groceries, that lives inside a group. You assign money to categories, not groups; a group's totals are the sum of its categories. See [Categories and groups](/concepts/categories-and-groups) for the concept. ## Create a category or group Use the add control to create a new group, or add a category inside an existing group. Give the group or category a name. You can add an emoji to a category to make it easy to spot in the grid. The new line appears in the grid, ready to assign money to. Setting up a fresh budget? You can add several categories at once from the grid header instead of one at a time. ## Rename Click a category or group name to edit it in place. Renaming does not affect the money in the category, its target, or its history — only the label changes. ## Reorder Drag a category or group to a new position. Order is yours to set — put the categories you fund first at the top, or group them however you scan fastest. The order you choose is the order you see everywhere the category list appears. ## Hide a category Hiding removes a category from the working grid without deleting its history. Use it for seasonal or finished categories you do not want cluttering the month, like a category for a trip you already took. A hidden category keeps all its past transactions and totals, and you can unhide it later. This is the right choice when a category has history. You cannot delete a category that has budgeting history — the app will point you to hide it instead. Hiding preserves your reports and reconciliation; deleting a category with history would break them. Delete is reserved for categories you created by mistake and never used. ## Related The concept behind the grid. Give a category a funding goal. Put money into your categories.
