What is the Cost Of Sales?

Cost of sales refers to the cost of goods sold or how much money a company pays to make a transaction. In general, this term refers to how much it costs a company to create and manufacture a product to market it. These expenses are considered as a required business expense for the overall stability of your company. That’s why you should record it as an expense on your Income Statements. Moreover, the cost of sales is also required to calculate your company’s gross profit and profit margin.


What to Include in Cost of Sales Formula?

In order to calculate the cost of sales, you need to include all your direct and indirect costs (expenses), which are incurred in the manufacturing and selling of the products. Therefore, you will need the following three values to calculate the COS.

  • Initial Inventory
  • Purchases
  • Ending Inventory

Formula for cost of sales

Initial Inventory – It’s the value of your existing inventory (items, etc.) At the start of an accounting year.

Purchases – It refers to the items you purchase or create in order to include them in your inventory for the accounting year.

Ending Inventory – It’s the amount of inventory leftover at the end of an accounting period. You can calculate it by calculating the inventory’s physical cost at the end of the year.


Calculation of Cost Of Sales – Example & Formula

At the start of a month, a company has £15,000 inventory available. During the month, it spends £20,000 on different inventory items, and at the end of the month, it has available £7,000 of inventory. So, let’s work out the cost of sales during the month!

Cost of Sales = Initial Inventory + Purchases – Ending Inventory

= £15,000 + £20,000 – £7,000

= £28,000
