Introduction

Cost of goods sold (COGS) is an essential measure that calculates the expenses directly associated with producing products or providing services. In simpler words, it’s the amount you spent to acquire the materials and labor used to create what you sell. Knowing how to calculate and analyze your COGS can help you make informed decisions about pricing your products, managing inventory, and improving your profit margins.

This article is for small business owners, managers, and anyone who wants to understand how to calculate and utilize COGS in their business.

How to Calculate Cost of Goods Sold: A Beginner’s Guide

COGS is a crucial metric to calculate the true cost of producing or providing products or services. To calculate your COGS, you need to add up all the direct costs associated with creating the product or service.

The formula for calculating COGS is:

COGS = Beginning inventory + Inventory purchases – Ending inventory

To break it down further:

  • Beginning inventory: The cost of the products or materials you had on hand at the beginning of the period you want to measure.
  • Inventory purchases: The cost of the products or materials you purchased during the period you want to measure.
  • Ending inventory: The cost of the products or materials you had on hand at the end of the period you want to measure.

Let’s take an example to illustrate how to calculate COGS:

Suppose you sell handmade bags, and the cost of materials for each bag is $20. During the period, you started with 50 bags in inventory ($20 x 50 = $1,000) and purchased materials worth $1,500 to make an additional 75 bags. At the end of the period, you had 20 bags worth $400 in inventory. To calculate your COGS:

COGS = Beginning inventory + Inventory purchases – Ending inventory

= $1,000 + $1,500 – $400

= $2,100

Your COGS for the period is $2,100, and you can use this figure to evaluate the profitability of your handmade bag business.

The Ultimate Guide to Determining Your Cost of Goods Sold

Calculating COGS using the formula is easy if you have all the data. However, determining COGS accurately can be complex. Here are some of the factors that can affect your COGS:

  • Material costs: The cost of the raw materials used to make the products.
  • Labor costs: The amount paid to employees or contractors to work on the products.
  • Overhead costs: The expenses associated with running your business, such as rent, utilities, and insurance.
  • Inventory valuation method: The method used to determine the value of the inventory, such as First-In, First-Out (FIFO), Last-In, First-Out (LIFO), or Weighted Average.

Choosing the right method to determine your COGS can affect your financial statements and tax obligations. To help you choose the best method for your business, here is a comparison of the three common methods:

First-In, First-Out (FIFO)

FIFO is the most commonly used method for determining COGS. It assumes that the first products bought or manufactured will be the first sold. This method is suitable for businesses that deal with perishable products or have a low turnover rate, as it avoids inventory spoilage or obsolescence.

Last-In, First-Out (LIFO)

LIFO assumes that the most recent products purchased or manufactured will be the first sold. It’s suitable for businesses that deal with non-perishable items that don’t expire or change in quality, as the older inventory remains unsold and is reported as an asset on the balance sheet. LIFO can be beneficial for tax purposes as it reduces taxable income by using more recent, higher-priced inventory costs.

Weighted Average

The weighted average method calculates COGS by averaging the cost of all inventory purchased or produced during the period. It’s particularly suitable for businesses with a high turnover of inventory and those dealing with homogenous products that can’t be easily distinguished by purchase date.

The method you choose depends on your business needs, accounting systems, and tax obligations. It’s essential to weigh the pros and cons of each method before deciding.

Accounting 101: Understanding The Cost of Goods Sold Equation

To calculate your COGS accurately, you need to know each component of the COGS equation:

COGS = Beginning inventory + Inventory purchases – Ending inventory

Beginning Inventory

The cost of the products or materials you had on hand at the beginning of the period you want to measure. It includes the cost of all finished goods, work-in-process goods, and raw materials you held in stock.

Inventory Purchases

The cost of all the products or materials you purchased during the period. It includes the original cost, freight charges, import duties, and any other additional costs incurred to bring the items into your inventory.

Ending Inventory

The total cost of all the products or materials you held in stock at the end of the period you want to measure. It includes the cost of all finished goods, work-in-process goods, and raw materials.

Examples to show how each component affects the cost of goods sold

Suppose you have a bakery business and calculate your COGS for the month of September 2021. The following are the scenarios:

  • Scenario 1: No beginning inventory, no ending inventory
    • You purchased $5,000 worth of flour, sugar, butter, and other baking materials during September.
    • COGS = Beginning inventory + Inventory purchases – Ending inventory
    • = $0 + $5,000 – $0
    • = $5,000

    Your COGS for September is $5,000.

  • Scenario 2: Beginning inventory but no ending inventory
    • You started the month with $1,000 worth of baking materials in inventory.
    • You purchased $5,000 worth of baking materials during September.
    • COGS = Beginning inventory + Inventory purchases – Ending inventory
    • = $1,000 + $5,000 – $0
    • = $6,000

    Your COGS for September is $6,000.

  • Scenario 3: Beginning inventory and ending inventory
    • You started the month with $1,000 worth of baking materials in inventory.
    • You purchased $5,000 worth of baking materials during September.
    • You ended the month with $500 worth of baking materials in inventory.
    • COGS = Beginning inventory + Inventory purchases – Ending inventory
    • = $1,000 + $5,000 – $500
    • = $5,500

    Your COGS for September is $5,500.

Simplifying Cost of Goods Sold Calculations For Small Businesses

Small business owners may find it challenging to calculate COGS accurately, especially if they don’t have a dedicated accounting department. Here are some tips to simplify the calculation process:
