Understanding ROAS on Amazon Advertising and How to Maximize It

What is ROAS? How Does it Affect Your Amazon Ads Strategy?

ROAS stands for Return Of Ad Spent, and it’s the ratio of revenue over ad spend.

It is a way to measure the effectiveness of your ads by comparing the return on investment with your ad spend.

It is important to measure ROAS because it can help you see which ads are working and which ones are not. You can also use ROAS to see how different ad sets affect one another and how much they should be bid.

How to Calculate ROAS on Amazon Ads, and What it Means

ROAS, or Return on Ad Spend, is the total revenue generated by an advertising campaign divided by the total ad spend. ROAS is calculated as follows:

ROAS = Total Ad Sales / Total Advertising Cost

This means that if you spend $100 but make $200 in profit, your ROAS would be 2. So for every $1 you spent on your PPC, you received $2 back. (This does not account for product cost or Amazon fees outside of Advertising)

ROAS Calculator for Your Amazon Advertising Campaign

ROAS Calculator is a tool that is used to calculate the Return on Advertising Spending for your Amazon advertising campaign. It helps you in understanding the financial benefits of your campaign and also helps you in analyzing the results of your campaign.

It provides a detailed analysis by calculating the profit generated from an Amazon advertising campaign. The ROAS calculator calculates the return on ad spend by dividing it by the cost per click or cost per conversion.

The ROAS calculator can be used to understand how profitable an Amazon advertising campaign is and whether it should be continued or not. It can also be used to compare two different campaigns and see which one has more profitability.

What is a good Amazon RoAS?

The short answer to this is… Depends on who you ask!

A profitable ROAS is influenced by a company’s operating expenses, profit margin, and overall health. There are many “right” answers for this but a common answer is an ROAS of 4:1 ($4 in revenue per $1 in advertisement).

Some businesses require a 10:1 ROAS to stay profitable and others can grow at a 3:1 ratio.

The Profit Margin dictates ROAS. Calculate the profit margin on a regular basis and make sure your ROAS goal is realistic for the current industry and market trends. A larger margin means you can survive low ROAS with minimum damage to the business; smaller margins require stricter adherence to your ROAS goal.

To know if your ad campaign is successful, calculate the Return on Advertising Spend. If you make at least 4 USD in revenue for every 1 USD spent on advertising, then it is a good campaign. (But each case is a case, and I’ve seen RoAS as high as 40 X)

Now, that’s just the baseline for determining a good RoAS. But essentially, a higher RoAS is what you want to aim for. 

The Amazon ROAS, also called the Return on Advertising Spending, is a great metric to use in order to evaluate your products. It addresses this by taking the number of sales and dividing it by the number of customer reviews you have, making it a ratio that typically should be over 1:1.

All things being equal, a higher Return on Advertising Spend (RoAS) is better for a business. However, if a company has high RoASs then it doesn’t guarantee that the business is profitable. One should also be wary of high production costs, Amazon FBA fees, shipping, and costs associated with creating content and designing ads.


How to Calculate Profit Margin (What is the Profit Margin Formula)


A number of ways exist to determine your profit margin. This all depends on the type of margin that you want to calculate, such as the operating or gross profit margin.

Calculating your company’s net profit margin may help you make more informed decisions down the road. To do so, follow this formula.

Here is the formula to calculate it:

Profit Margin = (Net Income / Revenue) X 100

For a more detailed explanation of how to find your profit margin, here are three steps to follow:

  1. Calculate your net income (Revenue – Expenses)

  2. Divide the net income by your revenue

  3. Multiply the result by 100 to get the profit margin percentage


How to Calculate Break-Even RoAS?


Many Amazon sellers use backward math to calculate their break-even ROAS, which can serve as a reference point while they run ads.

Here’s the formula to calculate break-even ROAS:

Break-even ROAS = 1 / Average Profit Margin %

For example, if your average profit is 60% then you break even if your ROAS is 1/60%=1.66

This means that with an Amazon ROAS below 1.66, you are losing money on the money you invest in online advertising.
