Setting up Amazon advertising for the first time raises one question almost every brand asks: how much does it actually cost? Whether you’re exploring Amazon FBA as a fulfillment model or looking to drive more visibility for products already listed, understanding ad spend is essential before you commit a single euro or dollar to a campaign. This guide breaks down the real costs, the key metrics, and the most common budget mistakes so you can plan smarter from day one.
What does it actually cost to advertise on Amazon?
Amazon advertising operates on a pay-per-click (PPC) model, meaning you only pay when a shopper clicks your ad. There is no fixed price for running ads on Amazon. Costs vary based on your product category, competition level, and the keywords you target. Most advertisers see average cost-per-click (CPC) figures ranging from a few cents to several euros, depending on how competitive the niche is.
Beyond the CPC, there are no mandatory setup fees for standard Sponsored Products campaigns. However, if you want access to Amazon DSP (Demand-Side Platform) for display advertising, minimum managed spend requirements apply and are significantly higher. For most brands starting out, Sponsored Products and Sponsored Brands are the entry points, and costs are entirely driven by your bidding strategy and daily budget caps.
It is also worth noting that advertising costs on Amazon are separate from any fees related to selling on the platform itself, such as referral fees or FBA fulfillment fees. When calculating your total cost of selling, all of these elements need to be factored in.
What budget do you need to start Amazon ads?
Technically, you can start Amazon ads with as little as one euro per day, since Amazon allows very low daily budget minimums. In practice, however, a realistic starting budget for meaningful data and results is between 300 and 500 euros per month per product or product group. Below this threshold, campaigns often lack enough impressions and clicks to generate actionable insights.
The right starting budget depends on three things:
- Your average selling price: Higher-priced products can absorb a higher CPC and still remain profitable.
- Your target ACoS (Advertising Cost of Sale): If your margins are tight, you need a lower ACoS, which often requires more selective bidding and a larger initial testing budget.
- Your category competition: In highly competitive categories, CPCs are higher, so you need more budget to stay visible.
A sensible approach is to treat the first one to two months as a learning phase. Set a budget you can sustain, gather keyword and conversion data, then optimize from there. Launching with too small a budget means your campaigns never exit the learning phase, and you draw conclusions from insufficient data.
How does Amazon decide what you pay per click?
Amazon uses a second-price auction system to determine your actual CPC. You set a maximum bid, but you only pay one cent more than the second-highest bidder in the auction, not your full maximum bid. This means your actual CPC is almost always lower than your maximum bid.
Several factors influence what you end up paying:
- Bid amount: Higher bids increase your chance of winning the auction and securing prominent placement.
- Ad relevance: Amazon rewards ads that are relevant to the search query. A highly relevant ad can win placements at a lower CPC than a less relevant competitor bidding higher.
- Conversion rate history: Amazon’s algorithm favors listings that convert well, since a sale benefits Amazon too. A strong sales history can lower your effective CPC over time.
- Placement type: Top-of-search placements typically cost more than product page placements because they generate higher click-through rates.
Understanding this auction dynamic is important because it means optimizing your product listing, your images, and your reviews is not just a conversion task. It directly influences your advertising efficiency and what you pay per click.
What’s the difference between ACoS and ROAS on Amazon?
ACoS (Advertising Cost of Sale) and ROAS (Return on Ad Spend) are two sides of the same coin, measuring advertising efficiency from opposite directions. ACoS expresses your ad spend as a percentage of the revenue it generated. ROAS expresses how much revenue you earned for every unit of currency spent on ads. A lower ACoS is better; a higher ROAS is better.
How to calculate ACoS
ACoS is calculated by dividing your total ad spend by your total ad-attributed revenue, then multiplying by 100. For example, if you spent 100 euros and generated 400 euros in sales, your ACoS is 25%. Your break-even ACoS is the point at which your ad spend equals your profit margin. If your margin is 30%, an ACoS above 30% means you are losing money on those ads.
How to calculate ROAS
ROAS is the inverse: divide your ad-attributed revenue by your ad spend. Using the same example, 400 euros divided by 100 euros gives a ROAS of 4, meaning you earned four euros for every euro spent. ROAS is often preferred when comparing performance across channels, while ACoS is more intuitive for Amazon-specific margin analysis.
Neither metric tells the full story on its own. A low ACoS might look great but could mean your ads are too conservative and missing growth opportunities. A high ROAS might mask the fact that you are only running ads on your brand name, which would have converted anyway.
How should you split your Amazon advertising budget?
A well-structured Amazon advertising budget is typically split across three campaign types: Sponsored Products, Sponsored Brands, and Sponsored Display. For most brands, Sponsored Products should receive the largest share of budget, around 60 to 70%, because they drive the most direct purchase intent. Sponsored Brands can take 20 to 30% for awareness and brand visibility, while Sponsored Display works well for retargeting with the remaining budget.
Within Sponsored Products, a practical split is:
- Automatic campaigns (20 to 30%): These help you discover new converting keywords and ASINs without manual research.
- Manual exact match campaigns (40 to 50%): Target your best-performing keywords with precise control over bids.
- Manual broad or phrase match campaigns (20 to 30%): Expand reach while still maintaining some targeting structure.
This split is not fixed. As you gather data, shift budget toward what performs. If your automatic campaigns are surfacing high-converting search terms, harvest those into manual campaigns and increase their budget share. Budget allocation should be a living decision, reviewed at least every two weeks.
What mistakes cause Amazon ad budgets to run out fast?
The most common reason Amazon ad budgets deplete too quickly is poor campaign structure combined with overly broad targeting. When campaigns run on broad match keywords without negative keywords in place, ads show for irrelevant searches, burning budget on clicks that were never going to convert.
Other frequent budget-draining mistakes include:
- Not setting dayparting or budget caps correctly: Without daily caps, a single high-traffic day can exhaust your monthly budget in hours.
- Bidding on highly competitive head terms too early: Generic, high-volume keywords are expensive and rarely convert well for new listings with limited reviews.
- Ignoring the search term report: This report shows exactly what shoppers typed before clicking your ad. Not reviewing it means you never add negative keywords and keep paying for irrelevant traffic.
- Running too many campaigns at once with too little budget each: Spreading a small budget across many campaigns means none of them gather enough data to optimize effectively.
- Launching ads on listings that are not conversion-ready: If your product images, title, bullet points, or reviews are weak, even well-targeted ads will drain budget without returning sales.
The fix for most of these issues is discipline in the setup phase. A clean campaign structure, a solid negative keyword list from day one, and a conversion-optimized listing are the foundations that make every euro of ad spend work harder.

Frequently Asked Questions
How long does it typically take for Amazon ads to become profitable?
Most new Amazon ad campaigns require 4 to 8 weeks before they generate reliable, optimizable data. During this learning phase, Amazon's algorithm is gathering impression, click, and conversion signals to serve your ads more efficiently. Profitability timelines vary by category and listing quality, but brands with conversion-ready listings and a realistic starting budget of 300–500 euros per month typically see meaningful improvements in ACoS between weeks 6 and 12. Patience and consistent optimization during this window are what separate campaigns that scale from those that stall.
Should I pause my Amazon ads if my ACoS is too high in the first few weeks?
Not immediately — pausing too early is one of the most common mistakes new advertisers make. A high ACoS in the first few weeks is normal because your campaign is still in its learning phase and hasn't accumulated enough data to bid efficiently. Instead of pausing, review your search term report, add negative keywords for irrelevant traffic, and tighten your targeting on keywords that are spending without converting. Only consider pausing a campaign if it has received a statistically significant number of clicks (typically 50 or more) with zero conversions and no signs of improvement.
What's the best way to find the right keywords for my Amazon campaigns?
Start by running an automatic Sponsored Products campaign for two to four weeks to let Amazon surface the search terms that real shoppers are using to find products like yours. Combine this with keyword research tools such as Helium 10, Jungle Scout, or Amazon's own Brand Analytics (if available to you) to identify high-volume, relevant terms. Once you have data, harvest the best-performing search terms from your automatic campaign into manual exact match campaigns where you can control bids precisely. This data-first approach is far more reliable than guessing keywords upfront.
Can I run Amazon ads if my product has very few or no reviews yet?
Yes, but you should set realistic expectations and keep a close eye on your conversion rate. Ads will drive traffic to your listing regardless of review count, but shoppers are significantly less likely to buy a product with no social proof, which means your CPC spend will yield fewer conversions and your ACoS will likely be high. A practical approach is to launch ads at a conservative budget while simultaneously enrolling in Amazon's Vine program or running follow-up email sequences to accelerate your first reviews. Treat the early ad spend partly as a visibility investment while your listing builds credibility.
How do I know if my Amazon ad budget is too low to be effective?
A clear signal that your budget is too low is when your campaigns are consistently hitting their daily budget cap before the end of the day — this means you are losing impressions and potential sales simply because you've run out of funds. Another indicator is when, after four or more weeks, your campaigns have fewer than 30–50 clicks per week, making it statistically impossible to draw meaningful conclusions about what's working. If you're seeing either of these patterns, consider consolidating campaigns to concentrate budget, or increasing your daily cap on your highest-performing campaigns before launching new ones.
What is TACoS and why does it matter beyond ACoS?
TACoS stands for Total Advertising Cost of Sale and is calculated by dividing your total ad spend by your total revenue — including both ad-attributed and organic sales. While ACoS only measures the efficiency of your paid traffic, TACoS gives you a fuller picture of how advertising is contributing to your overall business growth. A declining TACoS over time is a strong sign that your ads are successfully boosting organic rank and driving sales that no longer depend on paid clicks. Tracking TACoS alongside ACoS helps you understand whether your ad investment is building long-term marketplace momentum or simply sustaining short-term visibility.
Is it better to manage Amazon ads in-house or work with an external partner?
Managing Amazon ads in-house gives you direct control and can work well if you have a dedicated team member with PPC expertise and enough time to review performance at least weekly. However, Amazon advertising is increasingly complex — spanning multiple campaign types, placement strategies, and marketplace-specific dynamics — and the cost of learning through trial and error can quickly exceed the cost of working with a specialist. An external partner like Distrilink is particularly valuable when you're entering new European marketplaces, scaling multiple products simultaneously, or when you need advertising to connect seamlessly with fulfillment and listing operations rather than running in isolation.
