Cost of Goods Sold Formula calculates all the direct costs which are associated with the production of the various goods sold by the company and it is calculated by adding the beginning inventory of the company with the total purchases during the year and then subtracting the value of the closing inventory of the company from it.

What is the Formula of Cost of Goods Sold (COGS)?
Cost of Goods Sold (COGS) formula calculates the total cost involved in selling including the manufacturing costs as well as the cost to preparing a product or goods for sale.
Cost of Good Sold Formula = Beginning Inventory + Additions to Inventory – Ending Inventory
- Beginning Inventory: – inventory at the start of the year. This should be exactly the same as your ending inventory from last year.
- Additional Inventory: – inventory that you purchased during the year.
- Ending Inventory: – inventory at the end of the year.
COGS Basic Example
Inventory recorded at beginning of the fiscal year ended 2017 is $2000. Additional Inventory: Inventory purchased during the fiscal year 2017-18 is $1500. Ending Inventory: Inventory recorded at end of fiscal year ended 2018 are $1000
Calculate the Cost of Goods Sold?
- As per the cost of sales Formula, COGS is = 2000 + 1500 -1000 =$2500
- Therefore, $2,500 is the cost of goods sold.
COGS Formula (Extended)
Below is the COGS Formula extended to include
COGS Formula = Starting Inventory + Purchases – Purchase Returns & Allowances – Purchase Discounts + Frieght In – Ending Inventory
Components of the Cost of Goods Sold Formula
- Starting Inventory: Opening stock for the period.
- Purchases: Any purchase made for manufacture / setting up the product (e.g. raw material)
- Purchase Returns & Allowances: (a) Purchase Returns include items that are returned to suppliers (if any) (b) Allowances include any additional benefit received in the purchase chain for the product
- Purchase Discounts: Discounts received in the supply chain; reducing it from costs as this is accountable for the increase in profits
- Freight In: Transportation costs for the product raw materials to be brought to factory (or set up location)
- Ending Inventory: Closing stock for the period.
Examples of Cost of Goods Sold Formula
Let’s see some simple to advanced example to understand the Cost of Goods Sold Equation better.
Cost of Goods Sold Formula – Example #1
Consider a basic example of Company ABC manufacturing a packet of pens. The direct cost of manufacturing is $1.00 / packet. Below are statistics
- Opening Inventory as on 01/01/2017: 3500 packets
- Closing Inventory as on 12/31/2017: 500 packets
- Costs incurred during the year are as under:
- Purchase cost: $100,000
- Discounts received: $5,000
- Freight In: $25,000
Solution:
Cost of opening Inventory: 3500 packets x $1.00 = $3500.00
Cost of closing inventory: 500 packets x $1.00 = $500.00
4.9 (1,067 ratings)
Hence, the calculation of Cost of Goods Sold using COGS Formula is
- COGS Formula = $3,500 + $100,000 – $5,000 + $25,000 – $500
- COGS = $123,000
Cost of Goods Sold Formula – Example #2
Now consider an example of 2 products manufactured by a company. Below are statistics for Product X and Product Y:
For Product X-
- Opening Inventory: 5000
- Closing Inventory: 1500
- Cost per unit: $5.00
- Cost of materials: $120,000
- Cost of labor: $500,000
- Freight In: $40,000
For Product Y-
- Opening Inventory: 10,000
- Closing Inventory: 7,500
- Cost per unit: $2.00
- Cost of materials: $80,000
- Cost of labor: $300,000
- Freight In: $25,000
- Discount received: $5,000
Apart from the above direct costs, the manufacturing unit has the below overhead costs:
- Annual rent of manufacturing unit: $50,000
- Annual electricity charges: $75,000
- Salary of the supervisor: $70,000
Calculate COGS using Cost of Goods Sold Formula for an individual product.
Solution:
For individual products, total direct cost is as below:
For Product X –
- Cost of opening inventory: 5000 X $5.00 = $25,000
- Cost of closing inventory: 1500 X $5.00 = $75,000
- Direct cost = $120,000 + $500,000 + $40,000 = $660,000
As COGS is calculated using only direct costs, we should ignore the indirect costs related to these products. So the calculation of Cost of Goods Sold using COGS formula is as below
- COGS Formula = $25,000 + $660,000 – $75,000
- COGS = $610,000
For Product Y –
- Cost of opening inventory: 10,000 X $2.00 = $20,000
- Cost of closing inventory: 7,500 X $2.00 = $15,000
- Direct cost = $80,000 + $300,000 + $25,000 – $5,000 = $400,000
As COGS is calculated using only direct costs, we should ignore the indirect costs related to these products. So the calculation of Cost of Goods Sold using COGS formula is as below
- COGS Formula = $20,000 + $400,000 – $15,000
- COGS = $405,000
Cost of Goods Sold Formula – Example #3
Consider an example of the service industry – a courier firm. For a courier firm, the basic service is to route packets from their customers to appropriate destinations. During this activity, there are different types of costs included. Consider, company XYZ is a courier firm, which picks up consignments from their customers and then connects it further for the right delivery. Below are statistics for the year 2017.
- Pick up cost: $200,000
- Packing Material: $50,000
- Re-routing cost: $1,500,000
- Labour: $100,000
There may be other costs involved like traveling, administrative, selling and marketing etc. However, these are not included as they are indirect expenses.
So, the calculation of Cost of Goods Sold Formula-
- COGS Formula = $200,000 + $50,000 + $1,500,000 + $100,000
- COGS = $1,850,000

Relevance and Use Cost of Goods Sold Formula
Calculation of Cost of Goods Sold using COGS formula is critical for the company for the following reasons:
- It directly gives a cost of manufacture of the company’s individual product.
- Considers only direct costs, it cancels all chances of including any extra cost. Other administrative and selling costs are properly allocated later along with other products. Hence again, chances of ignoring other costs are ruled out as well.
- COGS is required for the company’s profit or loss account – it is the first reduction category in the Profit and Loss statement.
- It forms an integral part in financial ratio analysis to calculate ratios like Stock Turnover and Gross Margin Ratios.
Cost of Goods Sold Formula in Excel (with Excel Template)
Let’s see an example to understand the cost of goods sold equation with excel template.
In below screenshot is the Cost of Producing Product X.
So, using this data we have done the calculation of Cost of Goods Sold (COGS) for the Product X
Therefore, COGS will be –
Conclusion
Cost of Goods Sold is slightly different from the Cost of Production. Cost of Production would include the entire cost of producing the line of products by the company. However, cost of goods sold equation only calculates the cost incurred for the sold goods by the firm.
