Ending inventory costs are usually determined by taking a physical inventory of products or by estimating. The Internal Revenue Service (IRS) requires businesses with inventory to account for it by using the accrual accounting method. You most likely will need a tax professional to calculate COGS for your business income tax return. But you should know the information needed for this calculation, so you can collect all the information to include in this report. Consistently using COGS means using the historical data attained to determine seasonal trends. By using the historical changes, you can identify new opportunities that will drive the growth of your business.
While there’s only one formula for calculating COGS, companies can choose from several different accounting methods to find their specific cost. Each method is a different way of calculating the cost of the specific items sold in a given period. So, while COGS is an important metric, it’s far from a complete indication of a company’s total cost of doing business. The cost of goods sold is usually separately reported in the income statement, so that the gross margin can also be reported. Analysts like to track the gross margin percentage on a trend line, to see how well a company’s price points and production costs are holding up in comparison to historical results. The following exhibit shows where the cost of goods sold appears in the income statement.
The company’s COGS for the month is $60,000, representing the cost of materials used to manufacture and sell the furniture. The ending inventory is the value of unsold goods remaining at the end of the period. Businesses usually conduct a physical inventory count or use accounting records to determine this amount.
In this case, you might use the special identification method to find your inventory cost, resulting in a highly accurate COGS. This method tends to be used by businesses that sell bespoke or otherwise unique items, such as vehicles, real estate, and art or collectibles. You’ll typically find the cost of goods sold on the line directly underneath total revenue when looking at a company’s income statement. If you subtract the cost of goods sold from total revenue, you’ll get the gross profit figure. You must keep track of the cost of each shipment or the total manufacturing cost of each product you add to inventory. For purchased products, keep the invoices and any other paperwork.
During periods of rising prices, goods with higher costs are sold first, leading to a higher COGS amount. Your bakery made $6,000 in gross profit before other expenses like rent, utilities, and marketing. The cost of purchasing inventory and manufacturing expenses totaled $30,000 (COGS). In the fast-paced world of c-stores and gas stations, staying on top of how to track COGS in a convenience store can feel like a luxury you don’t have time for.
But it also helps determine how efficiently you are running your business. These are all questions where the answer is determined by accurately assessing your COGS. Companies that make and sell products or buy and resell goods must calculate COGS to write off the expense. The resulting information will have an impact on the business tax position. When inventory is artificially inflated, COGS will be under-reported which, in turn, will lead to a higher-than-actual gross profit margin, and hence, an inflated net income. LIFO is where the latest goods added to the inventory are sold first.
To understand the difference between operating expenses and the costs of goods sold, you must take into account how you attribute said costs. It’s the percentage of sales revenue a company retains after incurring all its COGS. It should be noted that the higher the gross margin, the more the amount a business can retain from every dollar of revenue.
Since we sold all the new laptops, their respective shipping charges are added to the direct cost. Let us calculate the Cost of Goods Sold, or COGS, using the formula we defined above. We will use the same scenario with FIFO and LIFO to understand how COGS changes with the inventory valuation method. If you shipped the items to your warehouse and paid the logistics provider, that is an additional direct cost.
While the gross margin is the standard metric used to analyze the direct costs of a company, the COGS margin is the inverse (i.e., one subtracted by gross margin). The list may also include commission expense, since this cost usually varies with sales. The cost of goods sold does not include any administrative or selling expenses. In addition, the cost of goods sold calculation must factor in the ending inventory balance.
Poor assessment of your COGS can impact how much tax you’ll pay or overpay. It can also impact your borrowing ability when you are ready to scale up your business. As you can see, calculating your COGS correctly is critical to running your business. Therefore, a business needs to determine the value of its inventory at the beginning and end of every tax year.
A retailer like Shane can choose to use FIFO (first-in, first-out) or LIFO (last-in, last-out) inventory costing methods. We then add any new inventory that was purchased during the period. This gives us the total cost of all inventory, but we can’t stop there. We only want to look at the cost of the inventory sold during the period.
Businesses can improve gross profit by increasing prices, lowering production costs, negotiating better supplier deals, and optimizing operations to reduce waste. Whether you’re a business owner looking to improve your bottom line or simply want to better understand financial statements, knowing how to calculate gross profit can be a game changer. Only companies that create products (including digital ones) can use the cost of goods sold – service industries use the concept of cost of revenue. For example, a company may offer a chargeable support service to people who buy its products. The first in, first out (FIFO) method assumes that any sales your business makes during a period will consist of the oldest inventory your business holds.
The formula to calculate the cost of goods sold calculates the direct costs of the goods a business sells during a specific period. It considers inventory at the start and end of the period, along with any new purchases made. Cost of goods sold is considered an expense for accounting purposes. This is because it represents direct costs incurred in the production or purchases of goods during the accounting period. However, it excludes all the indirect expenses incurred by the company. The WAC method calculates an average cost per unit by dividing the total cost of inventory by the total units available.

A company’s opening inventory is $100,000, purchases during the period amount to $150,000, and the closing inventory is $120,000. Going back to our example, Shane purchases merchandise in January and then again in June.
Once calculated, COGS appears as a direct expense below revenue on the income statement, impacting gross profit. To gauge whether your gross profit is on track, compare it to industry averages and look at trends over time. If your margin is lower than competitors, it may be a sign to adjust pricing, cut production costs, or improve efficiency. Are you trying to figure out how much money your business actually makes before covering expenses like rent, salaries, and marketing? It’s one of the most straightforward yet powerful financial metrics, giving you a clear picture of your profitability and efficiency.
In practice, however, companies often don’t know exactly which units of inventory were sold. Instead, they rely on accounting methods such as the first in, first out (FIFO) and last in, first out (LIFO) rules to estimate what value of inventory was actually sold in the period. If the inventory value included in COGS is relatively high, then this will place downward pressure on the company’s gross profit. For this reason, companies sometimes choose accounting methods that will produce a lower COGS figure, in an attempt to boost their reported profitability.
