How to Calculate Your Cost of Goods Sold on Amazon?

Understanding your Cost of Goods Sold (COGS) is essential for tracking profitability and making informed financial decisions as an Amazon seller accountant. COGS represents the direct costs involved in producing or purchasing the products you sell. Accurately calculating this figure helps you determine your actual profit margins and make strategic adjustments to improve business performance.

Step 1: Identify the Components of COGS

COGS includes all costs directly related to acquiring or producing your inventory. These typically include:

  • Product Costs – The price paid to your supplier or manufacturer for each unit.

  • Shipping and Freight Costs – Expenses related to transporting products from suppliers to your warehouse or an Amazon fulfillment center.

  • Amazon Fees – If you use Fulfillment by Amazon (FBA), storage fees and fulfillment costs are part of your COGS.

  • Packaging Costs – Any materials used for preparing and shipping the product.

  • Customs and Import Duties – If you source products internationally, these fees should be factored into the total cost.

Step 2: Use the COGS Formula

To calculate your Cost of Goods Sold, use the following formula:

COGS=BeginningInventory+Purchases–EndingInventoryCOGS = Beginning Inventory + Purchases – Ending InventoryCOGS=BeginningInventory+Purchases–EndingInventory

  • Beginning Inventory – The total cost of inventory available at the start of the period.

  • Purchases – The cost of additional inventory bought during the period.

  • Ending Inventory – The total value of unsold inventory at the end of the period.

For example, if you started with $5,000 worth of inventory, purchased an additional $10,000 worth of stock, and ended with $3,000 in unsold inventory, your COGS would be:

COGS=5,000+10,000−3,000=12,000COGS = 5,000 + 10,000 - 3,000 = 12,000COGS=5,000+10,000−3,000=12,000

This means that $12,000 is the cost associated with the products you sold during that period.

Step 3: Consider Additional Amazon-Specific Costs

If you're an Amazon seller, your COGS should also include:

  • Amazon Referral Fees – Typically 8-15% of each sale.

  • FBA Fulfillment Fees – Storage charges, picking, packing, and shipping.

  • Return and Refund Costs – Any costs incurred when customers return items.

Adding these expenses ensures a more accurate representation of your actual product costs.

Step 4: Keep Accurate Records

Proper bookkeeping is crucial for calculating COGS correctly. Use accounting software or Amazon Seller Central reports to track inventory, purchase invoices, and related expenses. Regularly updating records helps prevent miscalculations and ensures compliance with tax reporting requirements.

Why COGS Matters

Knowing your COGS allows you to:

  • Determine true profit margins and adjust pricing strategies.

  • Identify cost-saving opportunities by negotiating supplier prices or reducing overhead.

  • Ensure accurate tax reporting, as COGS is a deductible business expense.

By effectively managing your COGS, you can make smarter financial decisions and maximize profitability on Amazon.
