What is Cost of Sales?
The cost of sales, also known as the cost of goods sold (COGS), represents the total expenses incurred to produce or acquire the goods a company sells during a specific period. This includes direct costs such as raw materials, direct labor, and manufacturing overhead, along with freight and shipping costs. By calculating COGS, businesses can determine their gross profit, which is the difference between total revenue and cost of sales. This metric is essential for assessing profitability, setting accurate pricing strategies, and making informed financial decisions. Understanding COGS helps businesses manage inventory costs and optimize their operational efficiency.
How to Calculate Cost of Sales
Calculating this involves summing up all direct costs associated with producing or acquiring the goods sold during a specific period. Here’s a step-by-step guide to help you determine the cost of sales:
- Determine Beginning Inventory: Start by identifying the value of inventory on hand at the beginning of the period. This figure is crucial as it represents the starting point for calculating the cost of sales.
- Add Purchases or Production Costs: Include all costs associated with acquiring additional inventory or producing goods during the period. For manufacturers, this involves the cost of raw materials, direct labor, and manufacturing overhead. For retailers, this includes the purchase cost of new inventory.
- Calculate Total Available Inventory: Add the beginning inventory to the total purchases or production costs. This sum gives you the total value of inventory available for sale during the period.
- Subtract Ending Inventory: At the end of the period, determine the value of inventory still on hand. Subtract this ending inventory value from the total available inventory to get the cost of sales.
Formula:
Cost of Sales = Cost of Goods Available for Sale − Ending Inventory
i.e. Cost of Sales = (Beginning Inventory + Cost of Goods Purchased or Production Costs) − Ending Inventory
Case Study: Calculating Cost of Sales for a Pharmacy
At the beginning of the month, a community pharmacy had an inventory valued at $15,000, including prescription drugs, over-the-counter medications, and medical supplies.
During the month, the pharmacy purchased additional stock worth $30,000 to replenish its inventory and meet customer demand. By the end of the month, after fulfilling customer orders and managing stock, the remaining inventory was valued at $10,000.
To determine the cost of sales for the month, the pharmacy followed these steps:
- Beginning Inventory:
The value of the inventory at the start of the month was $15,000. - Purchases:
The pharmacy purchased additional medications and supplies worth $30,000 throughout the month. - Total Inventory Available:
Adding the beginning inventory to the new purchases, the total inventory available for the month was:
Total Available Inventory = $15,000 + $30,000 = $45,000 - Ending Inventory
At the end of the month, the pharmacy’s remaining inventory was valued at $10,000. By subtracting this from the total available inventory, the cost of sales was calculated:
Cost of Sales = $45,000 – $10,000 = $35,000

How to Calculate Cost of Goods Sold Without Ending Inventory
Calculating the Cost of Goods Sold (COGS) without the ending inventory figure can still be done, but you’ll need to estimate or use available data. Here are two methods to do so:
1. Using the Gross Profit Method
This method estimates COGS based on your expected profit margin.
- Determine Sales Revenue: Find out the total sales revenue for the period.
- Estimate Gross Profit: Use your historical data to estimate the percentage of profit you usually make from sales.
- Calculate Estimated COGS: Estimated COGS = Sales Revenue × (1 − Gross Profit Margin)
Example:
- If you made $100,000 in sales and usually have a 40% profit margin, the calculation would be: Estimated COGS = $100,000 × 60% = $60,000
2. Using the Formula with Estimated Ending Inventory
If you can estimate the ending inventory, you can calculate COGS as follows:
COGS = Beginning Inventory + Purchases − Estimated Ending Inventory
Example:
- Beginning Inventory: $15,000
- Purchases: $30,000
- Estimated Ending Inventory: $8,000
COGS = $15,000 + $30,000 − $8,000 = $37,000

How to Reduce Cost of Sales
To reduce the cost of sales, consider these strategies:
- Negotiate with Suppliers: Secure better terms or discounts to lower purchase costs. Strengthen relationships with key suppliers to gain access to exclusive deals or better credit terms. Regularly review and renegotiate contracts to reflect market changes and achieve optimal pricing.
- Improve Inventory Management: Optimize stock levels to avoid overstocking and reduce holding costs. Utilize inventory management software to adjust stock levels accordingly and forecast demand accurately. Implement just-in-time inventory practices to minimize excess inventory and associated carrying costs.
- Enhance Production Efficiency: Streamline production processes to cut down production costs. Invest in modern technology and automation to improve speed and accuracy. Conduct regular process audits to identify bottlenecks and areas for improvement, ensuring a more efficient workflow.
- Reduce Waste: Implement measures to minimize waste in materials and production processes. Introduce lean manufacturing principles to optimize resource usage and reduce excess. Regularly train staff on waste reduction techniques and conduct waste audits to identify areas for further improvement.
What Is Cost of Goods Available for Sale?
The cost of goods available for sale represents the total value of inventory that a business has on hand and available to sell during a particular accounting period. This includes:
- Beginning Inventory: The value of inventory that was available for sale at the start of the period.
- Cost of Goods Purchased: The total cost of inventory acquired during the period.
This metric is essential for calculating the cost of goods sold (COGS) and understanding your inventory’s impact on profitability. Accurately determining COGAS allows businesses to assess how much inventory is available for sale and to make informed decisions about pricing, purchasing, and inventory management.
How to Calculate of Cost of Goods Available for Sale
To determine the cost of goods available for sale, follow these steps:
- Determine the Beginning Inventory: Start with the value of inventory on hand at the beginning of the period. This figure is typically carried over from the ending inventory of the previous period.
- Calculate the Cost of Goods Purchased: This includes all costs associated with acquiring additional inventory during the period. This encompasses:
- Purchase price of inventory.
- Shipping and handling costs.
- Any other costs are directly attributable to bringing inventory to a saleable condition.
- Add the Beginning Inventory to the Cost of Goods Purchased: This sum gives you the total cost of goods available for sale for the period.
The formula to calculate the cost of goods available for sale is:
Cost of Goods Available for Sale = Beginning Inventory + Cost of Goods Purchased
Example
To illustrate, let’s consider a retail business:
- Beginning Inventory: $15,000
- Cost of Goods Purchased: $40,000
Using the formula:
Cost of Goods Available for Sale = $15,000 + $40,000 = $55,000
