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 sold by a company. This amount 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:

\[ COS = Beginning\ Inventory + Purchases - Ending\ Inventory \]

Where:

\( Beginning\ Inventory \) — Value of inventory at the start of the period
\( Purchases \) — Additional inventory purchased during the period
\( Ending\ Inventory \) — Value of inventory at the end of the period

Explanation: This formula calculates the actual cost of inventory that was sold during the accounting period by tracking inventory changes.

3. Importance of Cost of Sales Calculation

Details: Accurate Cost of Sales calculation is crucial for determining gross profit, analyzing business performance, preparing financial statements, and making informed pricing decisions.

4. Using the Calculator

Tips: Enter all values in USD. Beginning Inventory and Purchases should reflect actual business transactions. Ending Inventory should be based on physical count or perpetual inventory records.
