1. What is Cost of Sales?

Cost of Sales (COS) represents the direct costs attributable to the production or purchase of the goods sold by a company. It is a key financial metric used in trading accounts to determine gross profit.

2. How Does the Calculator Work?

The calculator uses the standard Cost of Sales formula:

\[ COS = Opening\ Inventory + Purchases - Closing\ Inventory \]

Where:

\( Opening\ Inventory \) — Value of inventory at the start of the period (GBP)
\( Purchases \) — Total purchases made during the period (GBP)
\( Closing\ Inventory \) — Value of inventory at the end of the period (GBP)

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