Are you still measuring your ad performance based solely on ACoS? You might be missing the real indicator of profitability, and it’s time to understand the difference between Amazon TACoS vs ACoS.
When sellers run Amazon PPC campaigns to drive visibility and sales, they often rely on ACoS to measure success. The problem is, ACoS only tracks ad sales and ignores organic growth, which means you might be measuring the wrong thing entirely.
If you’ve ever lowered your ad spend to achieve a “better” ACoS, only to watch total sales drop, you’ve already seen why this metric can be misleading. A low ACoS looks good on paper but can hide deeper issues with brand visibility and ranking.
In this blog, our Amazon agency explains the difference between ACoS and TACoS so sellers can focus on metrics that reflect true profitability and growth. We also show how using TACoS insights with expert execution helps drive sustainable sales and long-term business success.

Stop Guessing, Start Tracking TACoS
Don’t rely on ACoS alone. Learn how tracking TACoS can give you a full picture of profitability and growth.
Why ACoS Doesn’t Tell the Full Story
Around 79% of Amazon sellers use PPC campaigns because they know it’s one of the most effective ways to boost product visibility and drive sales. To measure their campaign performance, most rely on the ACoS metric since it shows how much of their ad spend goes toward generating ad-driven revenue.
What Is Amazon ACoS?
ACoS, or Advertising Cost of Sales, is the percentage of ad spend compared to the sales generated from those ads. In simple terms, it tells you how much you’re paying to earn each dollar in ad-driven sales.
To calculate ACoS, you divide your total ad spend by your total attributed sales, then multiply by 100. For example, if you spent $30 on ads and made $100 in sales, your ACoS would be 30%, meaning you spent $0.30 for every $1 you earned through ads.
The Reasons Why ACoS Alone Can Mislead Your Amazon Strategy
Although tracking ACoS is useful for ad performance, it doesn’t show the full picture of total business profitability. Here are the key reasons why relying only on ACoS is limiting:
- Only measures ad efficiency, not total sales.
- Optimizing for low ACoS can hurt long-term growth.
- Ignores the impact of ads on organic sales.
- Encourages short-term, reactive decision-making.
- Doesn’t account for total profit margins or costs.
TACoS: The Smarter Way to Measure Profitability
Using TACoS gives sellers a clearer view of how ad spend impacts total revenue, including both paid and organic sales. Yet many sellers still focus only on ACoS because they aren’t looking at the bigger picture of overall business growth.
What Is Amazon TACoS?
TACoS, or Total Advertising Cost of Sale, measures your ad spend as a percentage of all sales, including both paid and organic revenue. Unlike ACoS, TACoS gives a complete view of how your advertising impacts overall business performance.
To calculate TACoS, divide your total ad spend by your total sales and multiply by 100. For example, if you spend $50 on ads and generate $150 in total sales, your TACoS would be 33%, showing the true cost of driving all revenue, not just ad-attributed sales.
The Advantages of Using TACoS Instead
Using TACoS gives sellers a complete view of how ad spend affects overall business performance. Many sellers still focus only on ACoS, but TACoS highlights both paid and organic growth for smarter decision-making.
- Shows overall business health by including paid and organic sales.
- Measures whether organic sales are increasing alongside ad spend.
- Helps allocate ad budgets efficiently based on total revenue.
- Tracks long-term performance and sustainable growth.
- Provides a realistic view of profitability after advertising costs.

Strategies to Turn Amazon TACoS Insights Into Real Profits
Knowing how to determine your TACoS is one thing, but knowing how to use the insights from it is another, so you can make decisions that actually grow your business. There are strategies that can take TACoS data and turn it into real, measurable profit and long-term growth.
1. Continuous Monitoring and Adjustment
TACoS isn’t a set-and-forget metric; it requires regular calculation and review. Keeping it within a target range, like 10–20%, helps balance growth with profitability.
If TACoS starts drifting too high or low, adjust campaigns, budgets, and promotions accordingly. Continuous optimization ensures your ad spend fuels both immediate sales and sustainable brand growth.
2. Use Targeted Promotions to Manage TACoS
Running Brand Tailored Promotions (BTPs) at a small, fixed discount allows you to drive high-intent sales without causing a negative spike in TACoS. The cost of the promotion is predictable, making it easier to maintain a healthy overall TACoS.
Start small, around 10% off, and adjust if needed based on performance. This strategy helps retain top-tier customers, recover cart abandoners, and generate initial purchases that turn into long-term organic growth.
3. Utilize Historical Data for Context
High TACoS numbers can look alarming if you don’t have context. Comparing current performance to historical trends allows you to see if your account is actually improving over time.
This method also helps communicate results to stakeholders by showing progress relative to past campaigns. It turns what looks like a high TACoS into actionable insights and prevents unnecessary panic.
4. Focus on Organic Growth to Lower TACoS
Increasing organic sales is the most sustainable way to improve TACoS. By tracking keyword performance and organic trends, you reduce dependency on paid ads over time.
Advertising becomes a tool to support long-term growth, boosting visibility and Best Seller Rank. As organic revenue rises, TACoS naturally decreases, even if ACoS for individual campaigns fluctuates.
5. Hire a Professional Who Focuses on TACoS, Not Just ACoS
Knowing your TACoS is important, but interpreting it correctly requires expertise. Hiring a professional ensures that someone is actively monitoring total ad impact, not just ad-attributed sales through ACoS.
A skilled team can benchmark your TACoS against industry standards and historical trends. This approach helps you make decisions that grow organic sales and improve overall profitability, instead of just chasing a low ACoS number.
