Amazon ACoS Formula In Action

Let’s say that an ad campaign generates $300 in sales, and the ad campaign costs $30 to run. Use the ACoS equation as follows:

  • ACoS = 30/300 * 100 = 10%

The Advertising Cost of Sales is 10%.

How to Use ACoS to Measure Profitability

The Amazon PPC ACoS measurement will help you determine the profitability and success of your ad campaign.

How can you determine the most profitable ACoS for your product?

First, evaluate the profit margin of your product, the amount you take home from your sales after the costs associated with making and selling the product. 

The cost structure of a product will include shipping, Amazon fees, production fees, and others. After considering these costs, you will be left with your profit margin. 

ACoS Calculation Example:

Let’s say that shipping accounts for 15% of your profit, Amazon fees take up 30%, and product cost accounts for 35%. The resulting profit margin is 20%. 

What’s an Average ACoS on Amazon?

Determining your ACoS requires a thorough understanding of your products. Use your ACoS to determine how much to spend on ad campaigns.

As long as your ACoS is lower than your profit margin, you will not lose money on advertising. 

If your ACoS and profit margin are equal percentages, you have what is called a “break-even ACoS”. Here, you’re spending the entire profit margin on advertising, resulting in zero profit and zero loss. 

So what is a good ACoS for Amazon PPC?

A good ACoS Amazon depends on your marketing strategy and will generally range between 15-20%. The average ACoS is around 30%. 

Basically, your ACoS can keep varying depending on many factors including competition, product prices, and such.

Take your product selling plan into consideration and your Amazon ACoS strategy should match your intentions:

Low ACoS = High Profitability

High ACoS = High Visibility
