How Much Should ACoS Be? Amazon Advertising Benchmarks (2026)
Quick Answer
There is no single "right" ACoS for every seller. The ideal ACoS depends on your product margin, category, and business stage. As a general rule, your ACoS should always be lower than your profit margin. For most categories, a healthy ACoS ranges between 15% and 30%. During product launches, however, ACoS of 50-100% is normal and acceptable.
1. Industry Benchmarks Overview
Understanding what ACoS looks like across Amazon helps you set realistic targets. Based on aggregated data from thousands of sellers across 2024-2026, here are the general benchmarks:
- Excellent ACoS: Under 15% — highly efficient, typically seen in low-competition niches with strong brand recognition
- Good ACoS: 15% to 25% — the sweet spot for most established products with healthy margins
- Average ACoS: 25% to 40% — common across competitive categories, often acceptable during growth phases
- High ACoS: 40% to 60% — requires attention and is usually limited to launches or highly competitive categories
- Unsustainable ACoS: Over 60% — only justifiable during short launch windows or for high-margin products
Remember This Rule
Your ACoS can be anything as long as it is less than your profit margin. If your product has a 40% margin, a 35% ACoS is acceptable — you still net 5%. If your margin is 20%, a 15% ACoS leaves only 5%. Always benchmark against your own numbers, not just industry averages.
2. Category-by-Category Ranges
ACoS varies significantly by Amazon category due to differences in competition, price points, and conversion rates. The table below shows typical ACoS ranges for major categories in 2026.
| Category | Typical ACoS Range | Average ACoS | Competition Level |
|---|
| Electronics | 10% - 25% | 18% | Moderate |
| Clothing & Apparel | 20% - 40% | 30% | High |
| Home & Kitchen | 15% - 30% | 22% | Moderate-High |
| Beauty & Personal Care | 20% - 35% | 28% | High |
| Sports & Outdoors | 15% - 30% | 22% | Moderate |
| Toys & Games | 20% - 45% | 32% | Very High |
| Books | 5% - 15% | 10% | Low |
| Office Products | 12% - 25% | 18% | Low-Moderate |
| Pet Supplies | 15% - 30% | 22% | Moderate |
| Health & Household | 15% - 35% | 25% | Moderate-High |
These ranges are guidelines. Your actual ACoS will depend on your specific product, keyword strategy, and optimization level. Use them as a starting point for setting campaign targets.
3. The Margin Rule
The most important rule in determining your ACoS target is the Margin Rule: your ACoS must always be lower than your profit margin.
Here is the simple math:
Breakeven ACoS = Product Profit Margin (%)
How to Calculate Your Breakeven ACoS
- Start with your selling price (e.g., $50)
- Subtract: Amazon fees (referral + fulfillment), product cost, shipping, and other expenses
- The remainder is your profit per unit
- Divide profit by selling price to get your margin percentage
Example: You sell a kitchen gadget for $40. After Amazon fees ($12), product cost ($8), and shipping ($4), your profit is $16. Your profit margin is $16 ÷ $40 = 40%. Your breakeven ACoS is 40%. Any campaign with ACoS above 40% loses money.
The 10% Buffer Rule
Smart sellers add a 10% buffer below their breakeven ACoS. If your breakeven is 40%, target 30% as your maximum ACoS. This buffer covers returns, refunds, and the fact that not every ad-attributed sale is incremental — some would have happened organically.
4. Launch vs Maintenance
Your ACoS target should change dramatically depending on your product's lifecycle stage. Applying a maintenance ACoS to a launch campaign will starve your product of the visibility it needs to rank.
Launch Phase (Weeks 1-6)
- Acceptable ACoS: 50% to 100%+
- Goal: Generate velocity, win the Buy Box, collect reviews, build organic ranking
- Strategy: Use aggressive bidding on high-relevance keywords. Accept short-term losses for long-term organic traction.
- Duration: Typically 4-8 weeks depending on competition and product category
Growth Phase (Weeks 6-12)
- Target ACoS: 30% to 45%
- Goal: Maintain momentum while gradually reducing ad spend efficiency
- Strategy: Lower bids on expensive keywords, introduce phrase and broad match, begin negative keyword optimization
Maintenance Phase (Week 12+)
- Target ACoS: 15% to 25% (or breakeven minus 10% buffer)
- Goal: Profitability. The product now generates organic sales and ads serve as a supplement.
- Strategy: Focus on exact match, high-converting keywords. Use auto campaigns for discovery only within tight budgets.
5. Frequently Asked Questions
Is 30% ACoS too high?
30% ACoS is not inherently too high — it depends on your profit margin. If your product margin is 40%, 30% ACoS leaves a 10% net profit. If your margin is 25%, 30% ACoS means you lose 5% on every ad sale. Always benchmark your ACoS against your specific margin, not a generic number.
What is a bad ACoS percentage?
Any ACoS above your profit margin is technically bad. As a general benchmark, ACoS above 40% is considered high for most categories. ACoS above 60% is unsustainable unless part of a deliberate product launch strategy with a clear path to profitability within 8-12 weeks.
Does ACoS vary by ad type?
Yes. Sponsored Products typically have the lowest ACoS because they capture purchase-intent traffic. Sponsored Brands are 10-20% higher on average since they target awareness-stage shoppers. Sponsored Display ACoS can range from 20% to 50%+ depending on audience targeting. Factor ad type into your category expectations.
Can video ads improve ACoS?
Yes. Product videos can increase conversion rates by 15-25%, which directly lowers your ACoS by generating more sales from the same ad spend. Video content also boosts organic ranking over time, which feeds back into better organic visibility and lower dependence on paid ads.
What ACoS should I aim for on day 1 of a launch?
On day 1 of a product launch, focus on velocity, not efficiency. ACoS of 50-100% is normal. Target a reduction to 30-40% by week 4-6, and aim for your long-term margin-based target by week 10-12. The key is having a clear plan for progressive ACoS reduction — do not let high launch ACoS become permanent.
