1. What is the Cost Of Sales Formula?

The Cost Of Sales (COS) formula is a fundamental calculation in business studies that determines the direct costs attributable to the production of goods sold by a company. It represents the cost of inventory that has been sold during a specific period.

2. How Does the Calculator Work?

The calculator uses the Cost Of Sales formula:

Where:

• \( Opening\ Stock \) — Value of inventory at the beginning of the period
• \( Purchases \) — Additional inventory purchased during the period
• \( Closing\ Stock \) — Value of inventory at the end of the period

Explanation: This formula calculates the actual cost of goods that were sold during the accounting period by accounting for inventory changes.
