## What is COGS accounting?

As a brief refresher, your COGS is how much it costs to produce your goods or services. COGS is your beginning inventory plus purchases during the period, minus your ending inventory.

Simply put, COGS accounting is recording journal entries for cost of goods sold in your books.

When is cost of goods sold recorded? You only record COGS at the end of an accounting period to show inventory sold. It’s important to know how to record COGS in your books to accurately calculate profits. That’s where COGS accounting comes into play.

If you don’t account for your cost of goods sold, your books and financial statements will be inaccurate.

### Calculating COGS

Before you can jump into learning about recording cost of goods sold journal entry, you need to know how to calculate COGS. Follow the formula below to calculate your COGS:

COGS = Beginning inventory + purchases during the period – ending inventory

#### Example of calculating COGS

Let’s say your business’s beginning inventory is \$2,000 and you purchase \$500 of supplies during the period. Your ending inventory is \$200. Your COGS calculation would look like this:

COGS = \$2,000 + \$500 – \$200

## Why is COGS important?

Along with being on oh-so important financial documents, you can subtract COGS from your business’s revenue to get your gross profit. Gross profit shows you how much you are spending on COGS. Knowing your business’s COGS helps you determine your company’s bottom line and calculate net profit.

## How to record cost of goods sold journal entry

Follow the steps below to record COGS as a journal entry:

### 1. Gather information

Gather information from your books before recording your COGS journal entries. Collect information ahead of time, such as your beginning inventory balance, purchased inventory costs, overhead costs (e.g., delivery fees), and ending inventory count.

### 2. Calculate COGS

Calculate COGS using the formula:

COGS = Beginning inventory + purchases during the period – ending inventory

### 3. Create a journal entry

Once you prepare your information, generate your COGS journal entry. Be sure to adjust the inventory account balance to match the ending inventory total.
