1. What Is Cost Of Sales?

Cost of Sales (COS), also known as Cost of Goods Sold (COGS), represents the direct costs attributable to the production of goods or services sold by a company. It includes the cost of materials and labor directly used to create the product.

2. How Does The Calculator Work?

The calculator uses the standard Cost of Sales formula:

Where:

• \( COS \) — Cost of Sales (currency)
• \( \text{Beg Inventory} \) — Beginning Inventory value (currency)
• \( \text{Purchases} \) — Total purchases during the period (currency)
• \( \text{End Inventory} \) — Ending Inventory value (currency)

Explanation: This formula calculates the direct costs associated with goods sold during a specific accounting period by accounting for inventory changes.

3. Importance Of Cost Of Sales Calculation

Details: Accurate Cost of Sales calculation is crucial for determining gross profit, analyzing business profitability, managing inventory levels, and making informed pricing decisions.

4. Using The Calculator

Tips: Enter all values in the same currency unit. Beginning and ending inventory should be valued using consistent accounting methods (FIFO, LIFO, or weighted average).
