ROAS Calculation Simplified: Strategies for Maximizing Your Amazon Ad Spend

For Amazon sellers, Return on Ad Spend (ROAS) is a key metric that measures the revenue generated for each dollar spent on advertising. This guide explains how to calculate and optimize ROAS on Amazon to improve your advertising strategies and maximize profits. 

By understanding ROAS, sellers can identify the most effective campaigns and make data-driven decisions to enhance sales performance. Let’s explore the process of calculating ROAS and how to use this information to boost your Amazon success.

What is Return on Ad Spend (ROAS)?

Return on Ad Spend (ROAS) measures the revenue generated for each dollar spent on advertising. It is calculated by dividing the revenue from ad campaigns by the ad spend. This metric is crucial for Amazon sellers to understand the effectiveness of their advertising strategies and to optimize ad budgets.

Differences between ROAS, ROI, and ACOS:

  • ROAS focuses on the revenue generated from ad spend.

  • ROI (Return on Investment) considers the overall profitability, factoring in all costs.

  • ACOS (Advertising Cost of Sale) is the inverse of ROAS, showing the percentage of revenue spent on advertising.

Understanding these metrics helps sellers make informed decisions to maximize their advertising efficiency and profitability on Amazon.

How to Calculate ROAS

Return on Ad Spend (ROAS) is a key metric that helps Amazon sellers evaluate the effectiveness of their advertising campaigns. Here’s a breakdown of how to calculate it, with an example for clarity.

Definition and Formula:

ROAS is calculated using the following formula:

This formula indicates how much revenue is generated for every dollar spent on advertising.

Step-by-Step Calculation:

1. Determine Total Revenue from Ads:

Calculate the total revenue generated from your Amazon ads. This includes all sales directly attributed to your ad campaigns.

2. Calculate the Cost of Ads:

Sum up all costs associated with your Amazon advertising. This includes the total spent on all ad campaigns during a specific period.

3. Apply the ROAS Formula:

Divide the total revenue from ads by the total cost of ads. The result is your ROAS.

Example of ROAS Calculation for Amazon Ads:

Let’s say you ran an ad campaign for a month. Here are the figures:

• Total Revenue from Ads: $10,000

• Total Cost of Ads: $2,000

Using the ROAS formula:

In this example, the ROAS is 5. This means that for every dollar spent on advertising, you generated $5 in revenue. A higher ROAS indicates a more effective ad campaign.

Understanding ROAS helps Amazon sellers make informed decisions about their advertising strategies. By regularly calculating and monitoring ROAS, you can identify high-performing ads and allocate your budget more efficiently, ultimately driving higher profits and improving your overall marketing effectiveness.

Understanding the Differences: ROAS vs. ROI vs. ACOS

When evaluating the performance of your Amazon ad campaigns, it’s essential to understand three key metrics: 

Each provides unique insights into your advertising effectiveness.

ROAS (Return on Ad Spend):

Like mentioned above, ROAS measures the revenue generated for every dollar spent on advertising. The formula is:

Example: If you spend $500 on ads and generate $2,500 in sales, your ROAS is 5. This means for every dollar spent, you earn five dollars in revenue.

ROI (Return on Investment):

ROI evaluates the profitability of your investment, considering the net profit. The formula is:

Example: If you spend $500 on ads, generate $2,500 in sales, and have $1,500 in costs (including ad spend), your net profit is $1,000. Therefore, your ROI is:

ACOS (Advertising Cost of Sale):

ACOS indicates the percentage of sales spent on advertising. The formula is:

Example: If you spend $500 on ads and generate $2,500 in sales, your ACOS is:

This means that for every dollar you earned in sales, you spent 20 cents on advertising.

When to Use Each Metric:

  • ROAS: Best for understanding the efficiency of your ad spend. Use it to compare the performance of different campaigns and channels.

  • ROI: Ideal for assessing overall profitability, considering all costs. It provides a comprehensive view of your investment’s success.

  • ACOS: Useful for managing and optimizing ad budgets. A lower ACOS typically indicates more efficient spending.

Why Use These Metrics:

  • ROAS helps in pinpointing high-performing campaigns and optimizing budget allocation.

  • ROI offers a broader financial perspective, highlighting profitability beyond just ad spend.

  • ACOS allows for tight control over advertising costs, helping maintain healthy profit margins.

Understanding these metrics enables Amazon sellers to make informed decisions, optimize their marketing strategies, and maximize profitability. 

Why is ROAS Important?

  1. Performance Evaluation: ROAS helps sellers understand which ad campaigns are driving the most revenue. By regularly monitoring this metric, sellers can identify successful strategies and replicate them across other campaigns.

  2. Budget Allocation: Knowing the ROAS for different campaigns allows sellers to allocate their advertising budgets more effectively. Campaigns with higher ROAS can receive more funding, while underperforming campaigns can be adjusted or paused.

  3. Cost Management: Tracking ROAS helps sellers manage their advertising costs more efficiently. By ensuring that ad spend generates sufficient revenue, sellers can maintain healthy profit margins.

Benefits of Optimizing ROAS:

  1. Increased Profitability: Optimizing ROAS leads to higher profitability by ensuring that advertising dollars are spent on the most effective campaigns. This reduces wasted spend and maximizes return on investment.

  2. Better Decision Making: With detailed insights into which ads are performing well, sellers can make data-driven decisions to enhance their marketing strategies. This includes tweaking ad copy, adjusting bids, and targeting the right audience segments.

  3. Competitive Advantage: Sellers who optimize their ROAS can outperform competitors by achieving better ad placements and higher visibility. This competitive edge can lead to increased market share and sales growth.

Tracking and optimizing ROAS not only enhances ad performance but also contributes to a more profitable and sustainable business model on Amazon. 

What is a Good ROAS?

A good ROAS typically means that your ad campaigns are generating more revenue than the cost of the ads themselves. 

While the ideal ROAS can vary, many businesses aim for a ROAS of at least 4:1, meaning $4 in revenue for every $1 spent on ads. 

However, this ratio can differ significantly based on industry norms and the nature of the products being sold.

Industry Benchmarks and Target ROAS:

Different industries and product categories have varying benchmarks for ROAS. 

Here are some general guidelines:

  1. E-commerce: For e-commerce businesses, a ROAS of 3:1 to 5:1 is often considered good. This range indicates a healthy return on advertising investment, ensuring that the business remains profitable while covering ad costs.

  2. Consumer Goods: In the consumer goods sector, where margins can be tighter, a ROAS of around 2:1 to 4:1 is typically targeted. This allows for competitive pricing while still generating sufficient revenue to justify ad spend.

  3. Luxury Items: High-end and luxury products usually have higher profit margins, so a lower ROAS might still be acceptable. In this category, a ROAS of 1.5:1 to 3:1 can be deemed successful, as the higher profit per item compensates for the lower ratio.

  4. B2B Services: Business-to-business services often see a higher ROAS due to the higher value of each sale. A ROAS of 5:1 to 10:1 or more is common in this sector, reflecting the substantial revenue generated from each customer acquisition.


According to a report by WordStream, industries such as retail, beauty, and health have varying average ROAS, highlighting the importance of understanding your specific market. For instance, the retail industry often sees an average ROAS of 4:1, while beauty and health products might achieve a ROAS of 3:1.

Understanding what constitutes a good ROAS is crucial for optimizing your ad spend and achieving better profitability. By setting realistic targets based on industry benchmarks and continuously monitoring your ROAS, you can make informed decisions to improve your advertising strategy
