Definitions:

Predetermined Overhead Rate

A rate used to allocate manufacturing overhead costs to products, calculated at the beginning of the period based on estimated costs and activity levels.

Overapplied Overhead

A situation where the allocated manufacturing overhead cost is more than the actual overhead cost incurred.

Underapplied Overhead

A situation where the allocated manufacturing overhead cost is less than the actual overhead incurred, resulting in a cost that needs to be accounted for in the financial statements.

Job Order Costing

An accounting method that accumulates costs for individual jobs or orders, commonly used in manufacturing goods or providing services that are distinct or custom.
