What Is a Good ACoS for Amazon Ads? Benchmarks & Guide (2026)
Quick Answer
A good ACoS (Advertising Cost of Sale) on Amazon is any percentage that leaves you with a net profit. For most sellers in most categories, a "good" ACoS falls between 15% and 30%. Excellent ACoS is under 15%. But context matters: a 50% ACoS on a product launch that builds organic ranking is good, while a 10% ACoS that caps your total sales volume may not be. The real answer is: a good ACoS depends on your margin, category, and business goals.
1. The Short Answer
If you want a quick benchmark, here is how "good" ACoS breaks down for established products:
- Excellent: Under 15% — top-tier efficiency, common in books, electronics accessories, and branded products
- Good: 15% to 25% — the target zone for most profitable established products
- Acceptable: 25% to 35% — typical in competitive categories; often acceptable during growth phases
- High but sometimes justified: 35% to 50% — launch phase, highly competitive niches, or high-margin products
- Typically unsustainable: Over 50% — only works with very high margins or as a short-term launch strategy
Good ACoS vs Profitable ACoS
A "good" ACoS by industry standards might still lose you money if your margin is low. A 20% ACoS is excellent for a 30% margin product, but terrible for a 15% margin product. Always start with your breakeven ACoS (your profit margin) and work backward to set targets.
2. ACoS by the Numbers
The table below summarizes what a good ACoS looks like across different Amazon advertising scenarios in 2026.
| Scenario | Good ACoS | Excellent ACoS | Breakeven Warning |
|---|
| Established product, exact match keywords | 15-20% | Under 12% | Above 30% |
| Established product, broad match keywords | 20-30% | Under 18% | Above 40% |
| New product launch (first 30 days) | 50-80% | Under 50% | Over 100% for 60+ days |
| Sponsored Brands campaign | 20-35% | Under 18% | Above 45% |
| Sponsored Display (retargeting) | 15-25% | Under 12% | Above 35% |
| Auto-targeting campaign | 25-40% | Under 20% | Above 50% |
| High-competition category (toys, apparel) | 25-40% | Under 20% | Above 50% |
| Low-competition niche | 10-18% | Under 8% | Above 25% |
3. Good vs Bad ACoS Context
Whether an ACoS is good or bad depends on three factors: your profit margin, your campaign objective, and your product's lifecycle stage.
Profit Margin Context
This is the most important variable. Calculate your breakeven ACoS by determining your profit margin (selling price minus all costs, divided by selling price). Your ACoS is good if it stays below that number. Add a 10% buffer for safety.
Campaign Objective Context
Different campaigns have different jobs:
- Profit-focused campaigns: Low ACoS (under 20%) is good. These are your cash cows.
- Discovery campaigns: Higher ACoS (25-40%) is acceptable because the goal is finding new keywords, not immediate profit.
- Brand defense campaigns: Very low ACoS (under 10%) is expected since branded search converts at high rates.
- Product launch campaigns: High ACoS (50-100%) is normal. The goal is organic ranking, not immediate returns.
Lifecycle Stage Context
A 40% ACoS on day 90 of a product's life may be a problem, but the same ACoS on day 7 could be a success. As a product matures and builds organic ranking, your ACoS should naturally decrease because organic sales supplement ad-attributed sales. If ACoS does not trend downward over 3-6 months, it is a sign that your product may not have sustainable organic demand.
4. How Product Video Helps (VEONIB)
One of the most effective ways to improve your ACoS is by increasing your conversion rate. The logic is simple: if your ad spend stays the same, every extra conversion adds to the "Total Sales" side of the ACoS formula, bringing the percentage down.
Product video is one of the highest-impact conversion rate levers available to Amazon sellers. Data consistently shows that listings with product videos achieve 15-25% higher conversion rates compared to those without. Here is how video helps ACoS specifically:
- Builds trust instantly: Shoppers who see a product in action trust it more, reducing purchase hesitation
- Answers visual questions: "How does it work?" "What are the dimensions?" "How is it used?" — video answers these faster than text or images
- Reduces returns: Customers who watch a video have better expectations, leading to fewer returns and a more accurate ACoS picture
- Increases click-through rate: Listings with video thumbnails in search results attract more clicks, improving ad relevance scores
VEONIB is the easiest way to add video to your Amazon listings. Simply paste your product URL, and VEONIB generates a professional product video in about 60 seconds — no camera, no studio, no video editing skills needed.
5. Frequently Asked Questions
Is a 10% ACoS good on Amazon?
Yes, 10% ACoS is excellent for most categories. It means only 10 cents of every dollar goes to ad spend. However, check that you are not leaving sales on the table by being too conservative with bids. A 10% ACoS on $500 in sales is less valuable than a 20% ACoS on $5,000 in sales — consider the total profit dollar amount, not just the percentage.
What is a good ACoS for a brand new product?
For a brand new product with zero reviews and no organic ranking, a good ACoS is one that allows you to gain traction. Most successful launches operate at 50-100% ACoS for the first 3-6 weeks. The ACoS is "good" if it leads to organic ranking improvements and can be progressively reduced. Without a reduction plan, even a moderate ACoS is not good.
Is 50% ACoS ever good?
Yes, 50% ACoS can be good in three scenarios: (1) during a product launch with a clear reduction plan, (2) for products with profit margins above 60%, and (3) in hyper-competitive categories like toys (seasonal peaks) or apparel where 50% is near average. The key is knowing why your ACoS is 50% and having a strategy to improve it over time.
How does product video affect ACoS?
Product video improves ACoS by increasing conversion rates. With a 15-25% higher conversion rate, your ad spend generates proportionally more sales, which lowers your ACoS. Video also improves organic search ranking (more conversions signal relevance to Amazon's algorithm), reducing your reliance on paid ads over time — a double benefit for ACoS.
Should I target the same ACoS for all keywords?
No. Branded keywords should target under 10% ACoS. High-volume generic keywords may have 25-40% ACoS but drive substantial total volume. Long-tail specific keywords often achieve the best ACoS (15-25%) because they capture high-intent buyers. Set ACoS targets at the keyword level based on each keyword's role in your overall advertising strategy.
What is the average ACoS across all Amazon sellers?
The average ACoS across all Amazon sellers typically ranges from 22% to 35%. But this average masks huge variation: sellers with strong brands and optimized listings often achieve 10-20%, while new sellers in competitive categories may average 40-60%. Use the average as a loose reference, but always set your target based on your own profit margin and business goals.
