Advertising Cost of Sales (ACoS) on Amazon: What it is & Why it Matters

Cassandra Shaffer

March 17, 2021

Advertising is a big part of operating any online business, and Amazon is no different. Your Amazon Advertising Cost of Sales (ACoS) is a key metric to understand and measure how well your Amazon Sponsored Products campaigns are working.

What is ACoS on Amazon? How do you calculate ACoS?

Simply put, Amazon ACoS is how much you spend on Amazon advertising in order to generate $1 in revenue from that spend. Similar to Google’s Return on Ad Spend (ROAS), ACoS is a great metric for PPC marketers to see if advertising campaigns are profitable.

Your Amazon ACoS is calculated by taking your ad spend and dividing it by your number of sales. For example, if you launch an ecommerce campaign that generates $300 in sales, costing $84 over a certain time period, you would take $84, divide it by 300, and get your ACoS of 28% cost for every dollar of sales you make. This means you spend $0.28 on Amazon Advertising for every $1.00 of revenue from that advertising.

Why is ACoS important?

Your ACoS will help you determine how successful your ad campaigns are on Amazon and how much it costs to be a profitable seller. Of course, you’ll first need to define an ideal target for your ACoS so you can see just how much profit you’re making. To do this, you’ll need to look at the cost (and break-even point) of your products.

What is a good Amazon ACoS?

There is no perfect ACoS on Amazon that you should strive for, it can vary by company, product, and goal! So then how do you determine the best ACoS for your ecommerce campaigns? Ideally, you’ll want to get the highest sales revenue possible, combined with the lowest ACoS possible. Because low ACoS means high profitability and high ACoS means low profitability, sellers tend to push for low ACoS unless they are working on a specific awareness or sell-out strategy. We’ve outlined a few of the factors that can help you understand your best Amazon ACoS below:

  • Know your profit margins

    Ideally, your sponsored product campaigns will be profitable. But this means that your advertising spend needs to be less than your profit margin. Your profit margin represents the amount left after you’ve paid for all general costs, including shipping, production, employee salaries, and any fees. Knowing your current general costs helps you make more informed decisions about how much you can spend on advertising while still maintaining a profit. Knowing your costs is also vital for determining your break-even ACoS.

  • Determine break-even ACoS

    Your break-even ACoS is the amount you can pay for Amazon advertising where you won’t lose any profit, but you also don’t make any profit either. It’s a zero-gain, zero-loss balance that allows your business to keep running, but doesn’t let pave the way for growth. Your break-even ACoS isn’t necessarily the number you’ll use to determine whether your campaigns are successful, but it does help you see whether you’re netting a gain or loss.

To determine the break-even point, start with your ecommerce product and sale prices. For now, imagine your sale price is $10 and Amazon fees are $1. Then, assume that the cost of production is $3. So altogether you are paying $4 before the product is ever sold. Take that $4 of cost from the $10 sale price and you’re left with $6. This is your pre-ad profit, or how much is generated each time you sell your product organically (without any ads). Your break-even ACoS is $6, because if you spend all $6 on ads to get a sale, and you continue to spend $4 in upfront cost, you’re left with none of the $10 for profit.

  • Look at the right metrics

    While your ACoS is hugely important, you also need to look at a number of other metrics to get all the information you need. ACoS is just one factor to determine how successful your Amazon Advertising campaign is. Other metrics to keep in mind include the following:

    Impressions High impressions can suggest that your product is located in a popular category on Amazon. If your impressions are low, Amazon may be displaying your ad often, but your product may not be popular.

    Click-through-rate (CTR) CTR is a metric many PPC marketers are familiar with. If you have a low click-through-ratio, this can mean that your ad may not be performing well, or Amazon users weren’t attracted to click on it. Updating creative, copy, and strategy might help improve your CTR.

    Spend Consider how much you’re spending on your ads and your cost per click. You want to watch to make sure the cost you pay per click is worth the profit you gain from the click. If you spend too much, your profit margin will shrink. Auditing your spend can also help you ensure you aren’t overspending on advertising.

    Sales Look at how many clicks you had, and how many sales were a result of those clicks. If your conversion rates are low, you may need to work on the relevance of your ad to your product. Having the perfect placement and targeting won’t do much for sales if your audience expects one thing from the ad and gets something completely different from the product listing. Your ad should be engaging, but also relevant.

Determine target Amazon ACoS

In the earlier example, if you’re spending less than $6 on Amazon ads, you’re making a profit. If you’re spending more, you’re making a loss. You’ll need to consider all of the above factors, including key metrics like your click-through-ratio, and use this information to determine your target ACoS for Amazon.

To determine your ideal Amazon ACoS, you’ll want to find your ideal profit margin and work backwards. The average ACoS that advertisers strive for is between 15%-30%, but remember that every company, product offering, and marketing strategy is different, and can affect the ideal ACoS.

How an Amazon SEO Agency Should Be Serving Your Brand

How an Amazon SEO Agency Should Be Serving Your Brand

If you’re in the global ecommerce space, you are most likely aware of Amazon, and probably selling your products on the marketplace. With over $470 billion in sales in 2021 alone, Amazon stands as the third largest company in the world based on revenue. The ecommerce giant is a household name in the U.S. and working hard to grow its market share across five continents worldwide.

Having your products available on Amazon and being competitive there, though, are definitely two different things. If you want to really succeed on Amazon, you’ll need specialized insight into how Amazon works and how to make it work for you. So, for many brands, it’s a great idea to work with an Amazon Search Engine Optimization (SEO) agency.

At Pattern, Amazon SEO optimization service is one of our key competencies. We understand that technology, data-driven insights and expertise  are the most important tools brands can leverage to win top listing spots on digital marketplaces. With expert teams and years of experience, we help brands conquer the Profitability Death Spiral as they compete with other products and sellers online. We offer Amazon SEO agency services as a core solution to brands that need more resources to get ahead. 

What is an Amazon SEO Agency?

An Amazon SEO agency serves brands by improving their products’ rank and listing performance on Amazon. They make strategic decisions about ad spending and placement that lead to higher traffic, conversions, and revenue for ecommerce brands.

A great Amazon SEO Agency partner will:

Prioritize Your Success

Unfortunately, many Amazon SEO agencies profit in unfair ways from your brands’ perceived success based on the ROAS numbers they provide. This is done through including branded search terms in ROAS reports, which naturally skew listing performance

Let’s say, for instance, your brand is called “Annie’s” and you sell lollipops. Your brand has a very high likelihood of winning the top listing spots on Amazon for lollipop search terms that are paired with “Annie’s,” your brand name. So, SEO agencies will spend your ad money on those terms and report a very high ROAS. 

To avoid scenarios like these, it’s best to look for an agency that either calculates their profits on metrics other than your ROAS scores or weighs branded search terms differently in the performance metrics reports. Regardless of your Amazon SEO agency’s cost structure, you should align onbranded search terms before committing to a scope of work.

Provide Detailed Competitive Insight

A great indicator of a high-quality Amazon SEO agency is the level of insight they can provide into your competitors’ listing positioning and how it compares to yours. Data fanaticism is so important at Pattern that we’ve developed proprietary technology to display this exact information with precise detail for every brand we work with. In fact, you can find our free version here to see how you compare to some of your top competitors based on ASIN.

It’s certainly possible to improve your Amazon search performance with blind spending strategies. But a truly great solution will help you to know where your dollars are at their most powerful and competitive.

Reduce Your Ad Spend Over Time

Amazon’s A10 algorithm prioritizes customer satisfaction—it wants to show consumers the best products that align with their search intent to improve conversions and sales. So, the best way to gain momentum on Amazon is to work on incremental wins. 

Improving your performance on more obscure search terms that align with your customers’ search intent is a great way to increase ROAS for the long term. A10 will reward your success with better rankings on higher-volume search terms and the virtuous cycle can help you conquer your most-coveted listing spots. And the best part? This process of gaining momentum, if done right, will naturally decrease your ad spend over time as Amazon recognizes your value and works with you to keep your products at the top of consumers’ search results.

Amazon SEO Optimization and More

As an Amazon SEO specialist, Pattern knows how to help your brand win better success for long-term profitability on Amazon. With our data-driven tools and brilliant teams of ecommerce experts, we help brands with listing management, content optimization, Amazon ad strategies, and more.
