📊 Understanding Cost of Goods Sold (COGS)

Cost of Goods Sold, or COGS, is a simple way to measure the direct costs of making the items your business sells. Think of it as the "price of production." It tells you exactly how much you spent to create the products that brought in money.

💡 Expert Insight: "Knowing your COGS is like knowing the fuel efficiency of your car. If you spend too much on fuel (production), you won't have enough left for the rest of the trip (profit)."


🔍 What Makes Up Your COGS?

To find your COGS, you just need to look at three simple things that go into every product you make:

  • Direct Materials: This is the "stuff" your product is made of. If you're a baker, it's the flour and sugar. If you're a carpenter, it's the wood and nails.
  • Direct Labor: This is the "hands" that build the product. It’s the pay for the people who are actually on the tools or in the kitchen.
  • Overhead: These are the "hidden" costs of the workspace. Think of the electricity that runs the ovens or the rent for the factory floor.

🚫 What is NOT Part of COGS?

It is easy to get confused. COGS only counts things that go into the product. Other costs are called Operating Expenses (OPEX):

  • 📣 Ads & Marketing: Paying for Facebook ads or flyers.
  • 🏢 Office Costs: Rent for your office or pay for your accountant.
  • 📦 Shipping to Customers: The cost to mail the item after it is sold.
  • 💻 General Software: Your email service or website hosting.

🛠️ How-To: Identify Your COGS in 4 Steps

  1. Check Your Receipts: Look for money spent on raw materials this month.
  2. Count Your Workers: Only include pay for people who physically make the products.
  3. Look at the Factory: Include rent or power for the place where things are made.
  4. Ignore the Office: Do not include costs for sales, support, or management.
