Definition
Variable Costs, also known as variable expenses, are costs that vary directly with the level of production or sales volume. As production or sales increase, variable costs increase; conversely, as production or sales decrease, variable costs fall.
Examples
- Raw Materials: The cost of raw materials that go into the production of goods.
- Direct Labor: Wages for workers directly involved in manufacturing a product.
- Sales Commissions: Fees paid to sales agents based on the number of units sold.
- Shipping Costs: Expenses for transporting goods, which vary with the volume shipped.
- Utility Costs: Variable portion of utility bills associated with manufacturing, such as electricity costs that increase with machine usage.
