Last updated July 2026
Definition
Obsolescence is the loss of inventory value when items can no longer be sold or used — because of design changes, superseded parts, or expired demand.
Obsolete stock is the end state of unmanaged excess. Accounting requires reserving for it, and the write-offs hit earnings.
The defense is early detection and action: catch slow movers before they become obsolete, and monetize what already is.
