Are you struggling to understand the difference between Amazon ACoS vs TACoS? Well, fear not, because this article is here to guide you through these Amazon metrics.

Imagine this scenario: You’re an Amazon seller looking to optimize your Amazon advertising spend and boost your sales. But how do you know if your PPC ads are truly effective in driving organic sales and the overall profitability of your Amazon business?

That’s where understanding TACoS and ACoS comes in. By delving into these metrics, you’ll gain valuable insights that can help shape your ad campaigns for success on Amazon.

Understanding Amazon Advertising Metrics as an Amazon Seller

If you want to understand Amazon advertising metrics, it’s important to familiarize yourself with ACOS and TACOS. These metrics provide valuable insights into the effectiveness of your advertising campaigns and overall business performance on the platform.

Let’s dive in.

What is Amazon ACoS or Advertising Cost of Sale?

ACOS, or Advertising Cost of Sales, measures the amount spent on advertising compared to the revenue generated from those sales. It is presented as a percentage and is unique to Amazon.

To calculate ACoS (Advertising Cost of Sales), you need to divide your total ad spend by the sales generated from those ads.

The formula for ACoS is straightforward: ACoS = Ad Spend / Sales Generated from Ads.

How to calculate ACoS

To calculate ACoS, you divide your total ad spend by the sales generated from those ads. This formula gives you a percentage that represents the cost of advertising compared to the revenue it generates.

It’s an essential metric for understanding the effectiveness of your advertising campaigns on Amazon. By tracking ACoS, you can identify if your ad spend is resulting in profitable sales or if adjustments need to be made.

A lower ACoS indicates more efficient advertising and higher profitability. This data-driven approach allows you to make informed decisions to optimize your advertising strategies and maximize return on investment.

Understanding how to calculate and interpret ACoS is crucial for achieving success with Amazon PPC campaigns and belonging to a community of successful advertisers who are focused on driving growth and profitability.

What is Amazon TACoS or Total Advertising Cost of Sale?

On the other hand, TACOS, or Total Advertising Cost of Sales, takes into account both sponsored and organic revenue. It reflects the wider impact of your advertising efforts on total sales and profitability. By tracking TACOS on Amazon, you can assess the effectiveness of your ad spend in driving organic sales and improving profitability.

To calculate TACoS, you need to divide your total ad spend by the total sales generated from both ads and organic sources.

This formula allows you to measure the effectiveness of your advertising campaigns in relation to all revenue generated on Amazon.

How to calculate TACoS

The formula for calculating TACOS is dividing total ad spend by total sales generated. This equation allows you to measure the effectiveness of your advertising campaigns on Amazon. By understanding how much you’re spending on ads and comparing it to the revenue generated, you can gauge the impact of your advertising efforts.

To help you better understand how to calculate TACOS, here are four key points:

  • Calculate TACOS by dividing total ad spend by total sales generated.
  • Use the formula TACOS = Ad Spend / Total Sales Generated.
  • TACOS takes into account both sponsored and organic sales.
  • Tracking TACOS can provide insights into the effectiveness of your advertising spend and overall business performance.

The Difference Between ACoS vs TACoS on Amazon

Both of these metrics measure the relationship between your ad spend and your revenue. However, there is one distinct difference.

First, some quick definitions.

ACoS: ACoS stands for Advertising Cost of Sales. It measures your ad spend in relation to your ad revenue. The way to calculate it is: Ad Spend / Ad Revenue.

TACoS: TACoS stands for Total Advertising Cost of Sales. It measures your ad spend in relation to your total revenue. The way to calculate it is: Ad Spend / Total Revenue.

As you probably noticed, ACoS is only taking into account the revenue generated from your ads. Whereas TACoS measures your ad revenue plus your organic revenue.

That’s the main difference between the two.

How Do I Choose The Right Metric?

Why not both?

Both of these metrics are important and can offer different insights into your advertising campaigns and your business. In fact, we believe that by understanding and utilizing both metrics you’re getting a much more comprehensive view of your PPC marketing efforts.

First, let’s quickly summarize what these two metrics can show you.

One important thing to understand is that investing in paid advertising can help grow your organic sales over time. TACoS can help you to realize this strategy.

TACoS can help you to understand:

  • your overall profitability
  • your reliance on advertising
  • the effect of your ad sales on organic sales

ACoS, on the other hand, is focused specifically on how your ad spend is performing in a given period of time.

ACoS can help you to understand:

  • how your campaigns, ad group or keywords are performing
  • how to optimize your bids for profitability (breakeven ACoS)

How Do I Know if My ACoS and TACoS Are Good or Bad?

We say this a lot but it really all depends on your goals.

So, what would make an ACoS “bad”?

Lots of people might tell you that “you should keep your ACoS low” but we would suggest that should be changed to “you should keep your ACoS on target”.

Your ACoS might not be on target if you’ve exceeded your breakeven ACoS (which means your ads are eating up your profit margins) or you’re not meeting your ACoS goals.

While a high ACoS does typically mean that you’re spending more on advertising you might have a very good reason to do that (like a product launch). Also, sometimes you simply need to spend money to make money.

So, while a low ACoS can be great for profitability, a high ACoS can increase visibility, increase market share, and potentially lead to more profit in the long run.

This is where TACoS comes in!

The same basic rule applies. Your TACoS is “bad” if it’s not on target. Meaning if your ad spend is cutting into your profitability or you’re not hitting your goals then you should re-evaluate your campaigns.

The main rule of thumb is If TACoS < organic profit margin, then your overall business is profitable after advertising. That’s good!

That being said, decreasing or increasing TACoS can indicate certain trends in your advertising that you should be aware of.  

What Does It Mean When My TACoS Is Decreasing?

This typically means that your advertising is becoming more profitable. Some reasons for that might be:

  • Your ad spend and sales are going up but your ad spend is increasing at a lower rate.
  • Your total sales are staying the same and your ad spend is going down.
  • Your total sales are increasing but your ad spend didn’t change.

What Does It Mean When My TACoS Is Increasing?

This is usually an indicator that your advertising is becoming less profitable. Some reasons for that might be:

  • You’re spending more on ads but there’s no change in your total sales.
  • Your ad spend and total sales are increasing but sales are not high enough to offset your spending.
  • You’re spending the same amount on ads but your total sales are declining.
