A Complete Guide to Understanding and Optimizing Cost of Goods Sold

As a business owner, few metrics are more critical to your bottom line than cost of goods sold, or COGS. This represents the total cost of producing the goods you sell, including materials, labor, and overhead expenses. Gaining a firm grasp on your COGS is essential for maximizing profits, setting competitive prices, and ensuring the long-term financial health of your company.

In this comprehensive guide, we‘ll dive deep into everything you need to know about COGS. You‘ll learn exactly what this metric includes, how to calculate it using a simple formula, and how it impacts your other key financial numbers. We‘ll also share expert tips and real-world examples to help you optimize your COGS and keep more of your hard-earned revenue.

What is Cost of Goods Sold (COGS)?

At the most basic level, cost of goods sold refers to the direct costs of producing the products you sell. This includes the cost of raw materials and inventory, the labor required to turn those materials into finished goods, and any overhead expenses directly associated with the production process, such as equipment or factory space.

It‘s important to note that COGS only includes costs associated with sold products. Unsold inventory and indirect costs like marketing or administrative salaries are not included.

COGS is a key factor in determining your company‘s gross margin, or the percentage of revenue that exceeds your direct costs. The lower your COGS in relation to your total sales, the higher your gross margin and overall profitability.

COGS for Retailers vs Manufacturers

The exact expenses included in COGS can vary depending on the nature of your business:

• For retailers, COGS primarily consists of the wholesale purchase price of inventory, plus any additional costs like freight or warehouse expenses.

• Manufacturers must include all costs incurred during the production process, such as raw materials, packaging, and factory labor. Certain overhead expenses like utilities for a production facility may also be included.

It‘s important for business owners to work closely with their accounting team to ensure they are correctly calculating COGS based on their specific business model.

The COGS Formula Explained

The basic formula for calculating COGS is:

Beginning Inventory + Purchases During the Period – Ending Inventory = Cost of Goods Sold

Let‘s break this down with a couple of examples:

Retailer Example

Imagine a sporting goods store wants to calculate COGS for a particular quarter. At the beginning of the period, the store had $300,000 worth of inventory on hand. During the quarter, they purchased an additional $175,000 worth of inventory from suppliers. A physical count at the end of the period showed $225,000 of inventory still in stock.

Using our formula, the calculation would be:

$300,000 + $175,000 – $225,000 = $250,000 COGS

This means the total cost of the inventory the store sold during the quarter was $250,000.

Manufacturer Example

Now let‘s look at a company that makes its own products. At the start of the year, a small furniture brand had $85,000 worth of tables and chairs in its finished goods inventory. Over the course of the year, the company spent $360,000 on wood, hardware, and other raw materials. It also incurred $120,000 in labor costs for its production staff.

At the end of the year, the company had $65,000 of completed tables and chairs on hand. Its COGS calculation would be:

$85,000 + ($360,000 + $120,000) – $65,000 = $500,000

The total cost to produce the furniture sold that year was $500,000. Note that the cost of raw materials and direct labor were both included in the "Purchases During the Period" portion of the formula.

Important COGS Considerations

A few additional points to keep in mind when calculating COGS:

• Any inventory that is lost, stolen, or destroyed during the period should still be accounted for in your beginning and ending inventory numbers.

• If you manufacture products and also maintain a raw materials inventory, you must add the beginning raw materials inventory to purchases and subtract ending raw materials from the total.

• In some cases, additional costs like freight or warehouse rent may be included in COGS if they are directly associated with acquiring or storing inventory.

Always consult with a professional accountant if you are unsure about which costs should be included in your COGS calculation. Incorrect numbers can result in misstated financial reports and potentially costly errors.

Recording and Reporting COGS

Properly tracking your COGS is not only important for internal decision-making, but it‘s also required for external financial reporting and tax purposes. Here‘s what you need to know:

Recording COGS Transactions

Any time you incur a cost that is included in COGS, you need to record it as such in your accounting system. This might include bills from your suppliers, labor costs for production staff, or freight charges.

Be sure to link each transaction to the appropriate product or category so you can easily analyze your COGS by item if needed. Work with your bookkeeper to establish clear processes for coding expenses.

Reporting COGS on Financial Statements

COGS is typically listed near the top of a company‘s income statement, directly below revenue. This allows you to quickly see your gross margin, or the portion of your revenue that exceeds COGS.

If your business sells products in multiple categories, you may choose to list COGS and gross margin separately for each type of product. This can provide valuable insights into which products are most profitable.

Common COGS Reporting Errors

One of the most frequent mistakes businesses make is misclassifying indirect expenses as COGS. For example, the salaries of your sales staff or the cost of your accounting software should not be included, as they are not directly associated with production.

Misallocation of costs can make your margins appear higher than they really are, leading to inaccurate pricing and poor decision-making. Double check your numbers against your documentation to avoid these common pitfalls.

Optimizing Your COGS: Best Practices

Once you have a clear picture of your COGS, the next step is to look for opportunities to optimize this critical metric. While every business is different, here are a few proven strategies:

1. Negotiate with suppliers

Reducing the costs of your raw materials and inventory can have an immediate impact on COGS. Don‘t be afraid to shop around and request bids from multiple vendors. You may be able to secure discounts by buying in bulk, signing long-term contracts, or agreeing to promote a supplier‘s product.

Even small reductions in the cost of your inputs can translate to meaningful bumps in your margins over time. Make negotiation a regular part of your purchasing process.

2. Organize COGS by product/category

As mentioned earlier, tracking COGS at the category level can give you deeper insights into your profitability. You may realize that a particular product costs significantly more to produce than others.

With this data, you can make strategic decisions about where to focus your resources. You might raise prices, discontinue low-margin products, or look for ways to drive volume on your highest-margin items.

3. Embrace automation

Technology can help manufacturers in particular reduce their production costs. Automating repetitive tasks, using robots for precision assembly, or implementing inventory management software could allow you to increase output and reduce labor expenses.

While investing in automation requires an upfront cost, it may quickly pay for itself through reduced COGS and improved efficiency. Evaluate your current production process to identify opportunities for affordable upgrades.

4. Minimize waste and prevent theft

Any inventory that is damaged or goes missing prior to being sold can inflate your COGS and eat into your margins. Implement controls to carefully track your inventory levels and prevent avoidable waste.

This might include employee training on safe handling procedures, using security systems to deter theft, or improving your quality control processes. Any reductions in loss will translate directly to your bottom line.

5. Analyze COGS alongside gross margin

Finally, it‘s essential to view your COGS in relation to your gross margin. This will give you a better sense of the big picture.

Imagine your COGS increased 5% over the last quarter. At first glance, this may seem like bad news. However, if your gross margin is still well above your industry benchmark, a small increase in costs may not be cause for concern. It‘s all about context.

Regularly review your gross margin and set goals for where you want it to be. This will guide your overall pricing and production strategy and help keep your COGS in check.

COGS and Other Key Financial Metrics

Your COGS doesn‘t exist in a vacuum. To really get a handle on your business‘ financial health, you need to understand how it relates to your other key performance indicators. Here are a couple essential relationships to be aware of:

COGS and Gross Margin

As we‘ve mentioned throughout this article, your gross margin is the percentage of revenue that exceeds COGS. It‘s calculated using the following formula:

Gross Margin = (Revenue – COGS) / Revenue

If your COGS equals $60,000 and your total sales revenue is $200,000, your gross margin would be 70%:

($200,000 – $60,000) / $200,000 = 0.7 or 70%

Generally speaking, the higher your gross margin percentage, the more profitable your business. If you notice your margins slipping over time, it could be a sign that your COGS are creeping up and corrective action is needed.

COGS and Pricing

Your COGS should play a central role in how you price your products. After all, if you‘re not charging enough to recoup your costs, you‘ll quickly find yourself in financial trouble.

At a minimum, your prices need to cover your COGS and leave enough gross margin to pay for your indirect expenses like overhead and marketing. Many businesses use markups of 50% or more above COGS to arrive at their retail prices.

Keep an eye on your COGS as a percentage of revenue over time. If you notice an upward trend, you may need to consider raising your prices to maintain your margins. Always factor your costs into your pricing strategy to ensure profitability.

Real-World COGS Examples

To help illustrate these concepts, let‘s look at a couple real-world COGS case studies:

Winnebago Industries

Winnebago, a leading manufacturer of recreational vehicles, provides a great example of how managing COGS can drive profitability.

In its 2021 annual report, the company reported that its COGS decreased from 87% of revenue in 2020 to 82% in 2021. This was due in large part to Winnebago‘s strategic sourcing initiatives and its focus on high-margin products like luxury motorhomes.

As a result, gross margin increased 6% year-over-year, leading to record profits for the company. Winnebago‘s story demonstrates how optimizing COGS can have a massive impact on the bottom line.

Starbucks

On the flip side, Starbucks‘ 2018 annual report shows the dangers of rising COGS. The company reported that its cost of sales including occupancy costs increased by 13% year-over-year, driven by higher inventory costs and investments in store-level staffing.

This led to a decrease in Starbucks‘ overall operating margin, despite strong revenue growth. The coffee giant had to implement several cost-saving measures and raise prices to get its margins back on track in subsequent quarters.

The lesson here is that even the most successful businesses need to constantly monitor and optimize their COGS to maintain profitability. Letting costs creep up unchecked can quickly eat into your hard-earned revenue.

COGS Frequently Asked Questions

We‘ve covered a lot of ground in this guide to COGS, but you may still have some lingering questions. Here are answers to a few common queries:

What‘s the difference between COGS and operating expenses?

COGS includes only the direct costs associated with producing goods for sale, while operating expenses refer to all the indirect costs of running your business, like rent, marketing, and administrative salaries. Both are subtracted from revenue to calculate your profits, but COGS is typically listed separately on your income statement.

How do I account for inventory write-offs in my COGS?

If you have to write off unsold inventory at the end of an accounting period, the loss should be included in your COGS. This will increase your total costs and decrease your gross margin for that period. Regularly monitoring your inventory levels can help you avoid costly write-offs.

Can I include the cost of equipment in my COGS?

The cost of equipment used in the production process is typically not included in COGS. Instead, you would capitalize that cost as an asset and depreciate it over time. The depreciation expense would then be counted as an indirect operating cost rather than part of COGS.

How often should I review my COGS?

At a minimum, you should be calculating and analyzing your COGS every quarter. However, many businesses find it helpful to track this metric monthly or even weekly to quickly identify trends and make necessary adjustments. The right cadence will depend on the nature and complexity of your operation.
