Variable Costing

An accounting method that only includes direct variable costs (costs that vary with production levels) in the cost of producing goods.

Absorption Costing

A technique in accounting that ensures all expenses related to production, including direct materials, direct labor, as well as variable and fixed overhead costs, are factored into the product’s cost.

Fixed Costs

Fixed expenses that are unaffected by changes in production or sales volume, encompassing rent, salaries, and insurance.

Absorption Costing

A method of accounting for all the costs associated with manufacturing a product, including all direct costs and fixed and variable overhead expenses.
