Content classes
What the class column is for and why it changes the numbers.
Every item carries a content class — Electronics, Furniture, Clothing, Jewelry, and so on. The class is not decoration: it selects the useful life used to depreciate the item, and it maps to the category code in the exported spreadsheet.
Changing a class
Click the class cell and a searchable list opens showing all classes with the current one ticked. Type to narrow it, or scroll the full list if you are not sure what exists. Picking a new class sends the row for recalculation, and the depreciation cell shows a spinner until the answer comes back.
Useful life
Each class carries a standard useful life — five years for electronics, fifteen for furniture, three for children’s clothing. Straight-line depreciation divides the item’s age by that life. Useful life is internal to the math and never printed as a column on an export.
Classes Kevin will not auto-price
Jewelry, fine arts, firearms, and furs come back unpriced regardless of what a search might turn up. These need an appraisal or your own judgment, and a machine-picked comparable would not hold up.
