How to calculate cost of goods sold

To calculate the Cost of Goods Sold (COGS), you'll need three key pieces of information: the value of your inventory at the beginning of the accounting period, the cost of any purchases made during the period, and the value of the remaining inventory at the end. Simply input these amounts into the corresponding fields in our COGS calculator and click "Calculate COGS".

The formula used is:

COGS = Beginning Inventory + Purchases − Ending Inventory

This calculation will provide you with the cost of the inventory that was sold during the period, helping you understand the direct costs associated with the products you've moved.

To make this process even more straightforward, our Cost of Goods Sold calculator automates these calculations, allowing you to focus on interpreting the results and planning for business growth. Just input your inventory costs and purchases, and let the calculator do the rest.

The importance of accurately calculating COGS


Understanding your Cost of Goods Sold (COGS) is crucial for your taxes. It represents the total amount you invested in delivering your products to customers, which in the U.S. is a tax deductible business expense.

By including more qualifying items in your COGS calculation, you can effectively reduce your small business tax liability.

COGS also provides valuable insights into your business's overall performance. When you subtract COGS from your revenue, you arrive at your gross profit—revenue minus the cost of sales. This number allows you to calculate your gross margin—how much money you’re making from each product you sell.

Gross margin is a key metric to monitor; it can help you determine if your pricing is too low or if your production costs are too high. This alone makes calculating COGS essential.

The better your business records and bookkeeping, the easier it will be to cost out your inventory and determine your COGS. Accurate records will also make it easier to appropriately determine the amount of your COGS tax deduction.

Automating your COGS calculation


COGS is included as a line item on a profit and loss statement. Your bookkeeper and most bookkeeping software will provide this financial report for you.

At Bench, our team of bookkeepers prepare a monthly profit and loss statement that can be accessed anytime in our easy-to-use software.
