What does AcoS mean? Amazon ACos Definition

ACoS is the acronym for the Amazon Cost of Sales. The Advertising Cost of Sales is the amount you pay for advertising for every penny of revenue you generate. In addition, the ratio can also be viewed as the spend ratio as compared to the target sales.

It’s a key metric that guides your Amazon advertising strategy that you need to pay attention to in Amazon PPC. You decide how to bid on search terms based on your ACoS, which is a percentage measure. When it comes to Amazon PPC advertising, ACoS is everything.

Aside from ACoS for the entire account, you can also calculate ACoS at any level, such as at a campaign, ad group, ASIN, or keyword-level ACoS.

What is the ACoS Amazon Formula?

Essentially, ACoS stands for advertising cost per sale or the cost of reaching a customer and selling to them. The formula itself is fairly straightforward, but there are a few ways you can calculate it.

Achieving an average cost of sale on Amazon is a metric that reveals how much profits can be expected over a given period of time. The best way to determine this is sometimes to solve the equation using PPC or other advertising methods. As a ratio of ad spending to target sales, ACoS is also known as return on investment.

As you can see, the equation looks like this:

The ACoS calculation looks like this: If your ACoS is 25%, you paid $0.25 for every dollar you earned or $25 for every $100.

In order to measure the success of your campaign, Amazon ACoS is an important metric.

The Return on Ad Spend (ROAS) concept is copied from Google Ads, a PPC marketing platform. 

What is the meaning of your Amazon ACoS?

The ACoS shows how much of every dollar earned through advertising was spent on ads.

Consider the case of a campaign that generated $400 of advertising sales. This campaign costs $100 in ads, so ACoS = 100 / 400 x 100 = 25%.

As a result, 25 cents have been spent on advertising for every dollar generated.

How does PPC differ from ACoS?

You can use Amazon ACoS to gauge the profitability of your account, but it doesn’t work like PPC. ACoS focuses on improving the profitability of existing traffic, while PPC focuses on bringing in new traffic. The perception that a high ACoS equates to a high PPC revenue is not always accurate. It is beneficial to understand ACoS for large retail accounts that are looking for a more concrete method of evaluating their accounts’ success.

It is important to maximize your advertising costs per sale and to reach the right audience when running Amazon ads.

What Is a Good ACoS on Amazon and how do I reduce it?

There are many variables that affect ACoS, including the marketplace, the ad type, the competition, the product price, and many others. Below is a general overview of ACoS values on Amazon across different categories.

Ad campaigns cost more than you earn, so try reducing your Amazon ACOS or increasing your earnings if you’re spending more than you’re earning. In order to determine where your funds should be directed and where your expenditures can be optimized and reduced, it is useful to examine successful and unsuccessful advertising campaigns. 

Also, make sure your keywords are correct. Reaching a broader audience can be achieved through these metrics. Including at least 25 keywords is recommended for advertising with Sponsored Brands. A keyword may also consist of a phrase, a broad keyword, or even the name of a product or brand. To reach your optimal audience, you should combine a variety of keyword types.

Reviewing the right metrics

Among key performance indicators (KPIs), Amazon ACoS is one. Aside from impressions, conversion rates, and click-through rates (CTRs), advertising metrics also include conversion rates. In spite of the fact that Amazon ACoS is a good starting point, it is important to consider multiple metrics in order to determine which works best for you and what needs to be altered to improve your results further.


Determining a target ACoS is essential. There will be a different target ACoS for each brand. Nevertheless, the first step is achieving break-even ACoS and comparing it to your profit margin. Your next step is to determine what your brands and campaigns should aim for: Are they trying to increase sales? What is the impact on brand awareness? In your marketing strategy, you can determine the value of Amazon ACoS once you have decided.

Factors that affect ACoS?

There is a common misconception that the highest bidder always gets the best spot – but that isn’t always true. While cost-per-click plays an important role, it is not the only one. 

The following two factors determine ad placement: 

  • CPC: A person with a high CPC is more likely to win prime advertising space on Amazon. 
  • Quality: The quality of the ad also depends on the probability of a customer clicking on it. Using Amazon PPC, Amazon only receives payment for clicks. Impressions do not help Amazon. An ad’s placement is based on how likely it is for customers to click on it. 

Ads that convert well and generate clicks can be bid lower for an ad spot if they are generating clicks. With Amazon PPC, a good product listing and ad copy play a critical role in reducing ACoS (advertising cost of sale) and maximizing ROI (return on investment). 

What is a good ACoS for Amazon?

There are a few guiding principles for a good Amazon ACoS, but there is no universal benchmark. The first benefit of a low ACoS is higher returns. When your ACoS is low, you spend fewer ads per sale and spend less on advertising. The second thing to note is that your break-even ACoS is equal to your product’s profit margin. In other words, if your ACoS is higher than your profit margin, then you are spending more money advertising a product than you are making from sales. 

Additionally, it is a good idea to compare your ACoS with those of your competitors in the same category. Typical ACoS will vary depending on the market and will not be uniform across eCommerce. As a result, you can analyze your competitors’ ACoS in order to determine if yours is good or not.

How do I find my ACoS on Amazon?

You can calculate your Amazon ACoS by dividing your ad spend by your ad-generated sales revenue. You can do this at any level, from looking at the whole account down to individual search queries for a given product.

In terms of calculating your ACoS, Amazon is second-to-none for data clarity, as all sales generated by Amazon ads are directly attributable. They happen within Amazon and the steps of the buyer journey are all easily traceable. This level of cohesion is hard to achieve on other channels where customer contacts occur on distinct platforms (or offline channels).

Any business with more than a couple of products will quickly realize that manually tracking their ACoS on Amazon becomes incredibly time-consuming, which is why sellers who are serious about Amazon advertising will opt for an automated software solution (like Perpetua) to monitor the ACoS of all their ad campaigns.
