Advanced Concepts

While prime cost focuses on direct materials and labor, conversion cost includes direct labor and manufacturing overhead. Understanding the difference is crucial for accurate cost accounting and pricing strategies.

Prime costs typically vary directly with production volume, making them variable costs. This relationship is essential for break-even analysis and production planning.
