1. What is Cost of Sales?

Cost of Sales (COS) represents the direct costs attributable to the production of goods sold by a company. It includes the cost of materials and direct labor used to create the product, similar to Cost of Goods Sold (COGS) but typically used in service industries.

2. How Does the Calculator Work?

The calculator uses the 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, managing inventory levels, and making informed pricing decisions.

4. Using the Calculator

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

Q2: How often should Cost of Sales be calculated?

Q3: What if Ending Inventory is higher than Beginning Inventory plus Purchases?
