The short answer
Amazon PPC has no set price. Amazon's own description of Sponsored Products is that campaigns have no monthly or upfront fees: you bid the maximum you are willing to pay when a shopper clicks your ad, and you set a daily budget. Amazon's ads FAQ adds that sponsored ads remain cost per click with no minimum spend.
So the real cost is two numbers you control, your bids and your budget, plus one you do not: how much competing sellers bid for the same shoppers. Amazon does not publish an average cost per click, and neither does our benchmarks report, so this guide gives you the method to size your own cost rather than a number to copy.
Cost per click only tells you the price of traffic. What decides whether Amazon PPC pays is the share of each sale that goes to advertising, which is what ACoS measures.
How Amazon PPC pricing works
Sponsored Products ads are sold through an auction. You bid the most you will pay for a click on a keyword or product target, and Amazon says that the more competitive your bid, the more likely your ad is to be displayed when it matches a shopper's query.
You are charged when a shopper clicks, not when the ad is shown. Amazon's guide to cost per click explains that the final cost per click is usually determined by an auction and is based on your adjusted bid plus additional factors. It defines the maximum cost per click as the highest amount you could be charged for a click, which is your base bid plus any adjustments from settings such as dynamic bidding or cost controls. If you let dynamic bidding raise bids for placements likely to convert, your ceiling rises with it.
Sponsored Products and Sponsored Brands are both bought on bids. Amazon's pricing transparency guide says it charges advertisers based on customer action, typically per click (CPC), per 1,000 viewable impressions (vCPM) or per 1,000 impressions (CPM), depending on the ad product. Display and video bought through Amazon's managed service are a different budget class: its FAQ says that option typically requires a minimum spend of $50,000 (US).
What drives your cost per click
Demand for the keyword is the biggest factor. Amazon's own guide puts it plainly: the more in-demand a keyword is or the more visible the placement, the higher the advertising costs. Broad category terms where many sellers compete cost more than specific, long-tail searches.
Relevance matters as well as the bid. Amazon's pricing transparency guide says that when it chooses Sponsored Products and Sponsored Brands ads, it considers the keywords advertisers bid on, the amount they bid, and shoppers' expected interest in the offer, based on the offer itself, similar offers and past purchases. A listing that converts well is a better candidate for the same click.
Your own bid settings change the price too: bid adjustments and dynamic bidding raise the maximum you can be charged for a click. Finally, seasonality: more sellers compete for the same shoppers in peak periods such as the run-up to the holidays.
ACoS and TACoS: reading what you pay
On Amazon, cost is usually read as a ratio rather than a click price. ACoS, advertising cost of sales, is ad spend divided by the sales those ads generated, times 100. Spend $250 to generate $1,000 of ad-attributed sales and your ACoS is 25%. Amazon's guide to ACoS notes that ROAS is its inverse: ad revenue divided by ad spend.
Amazon's own rule of thumb is the one to hold on to: to stay profitable, your ACoS needs to be lower than your profit margin. If a product keeps 30% of its price after product cost, Amazon's fees and shipping, any ACoS under 30% makes money on the ad-driven sale and any ACoS above it loses money. The break-even ROAS calculator works out that line from your margin.
TACoS, total advertising cost of sales, divides ad spend by all of your sales, including organic and repeat orders. It answers a different question: whether advertising is growing the whole business, or carrying a bigger share of it. A falling TACoS while sales grow is the pattern you want.
Your target ACoS comes from your margin, not from a competitor's account. Work it out per product, because margins differ across a catalog.
How much should you budget?
Work backwards from the sales you want rather than picking a number. The simplest Amazon formula is: monthly ad budget equals target ad-attributed sales multiplied by target ACoS.
A worked example, using round numbers to show the arithmetic: you want $10,000 a month in ad-attributed sales and your margin supports a 25% target ACoS. The budget is $10,000 multiplied by 0.25, or $2,500 a month, about $81 a day across a 31-day month.
If you would rather budget from clicks, the same logic as our Google Ads cost guide applies: target orders, divided by your conversion rate, multiplied by your cost per click. Take the conversion rate and cost per click from your own search term reports once a campaign has run for a few weeks, and plug them into the PPC budget calculator. Our guide on how to set a PPC budget covers splitting it across campaigns.
A launch budget so small it buys a few clicks a day cannot tell you which keywords convert. Fund the first weeks with enough clicks to judge, then cut what does not sell.
How daily budgets work on Amazon
For Sponsored Products you set a daily budget per campaign, and Amazon treats it as a daily amount spent over a calendar month. Its own example: at a $100 daily budget, you may receive up to $3,100 worth of clicks in that calendar month, assuming a full 31-day month.
Amazon also says daily budgets are not paced through the day, so a small daily budget could be spent in a few minutes if many shoppers are interested in your products. When a campaign runs out early every day, it misses the rest of the day's shoppers; that is a sign the budget, not the bid, is the constraint. Amazon states that the final cost will never be more than the amount you have set for the campaign's duration, and you can raise or lower the daily budget once ads are live.
Ad costs vs Amazon's seller fees
Advertising is only part of what Amazon takes from a sale. Every item sold also pays a referral fee: Amazon's pricing page says you pay a percentage of the total price or a minimum amount, whichever is greater, and the percentage varies by product category. The total price includes the list price plus shipping and any gift-wrap charges.
On top of that comes a selling plan. Amazon lists the Professional plan at $39.99 a month and the Individual plan at $0.99 per item sold. Fulfillment by Amazon fees, if you use it, are separate again.
These fees come out of your margin before advertising does, which is why they belong in your break-even ACoS. A product that looks profitable on its list price can have little room left for ads once the referral fee and fulfillment are paid.
Ad spend vs agency fees
Everything above is ad spend, the money that goes to Amazon. If an agency or freelancer runs the account, their fee is separate and comes on top. The common models are a percentage of ad spend, a flat monthly retainer, a hybrid of a base fee plus a percentage, and a share of the sales the ads produce. Each rewards different behaviour: a percentage of spend grows with your budget, while a retainer does not.
iClick scopes pricing on a call, based on the size of the catalog and the channels involved. Our PPC management pricing guide explains how the models compare, and you can see how iClick runs Amazon Ads alongside Google and Meta.
How to lower what you pay
Fix the listing first. Amazon weighs shoppers' expected interest in your offer, and a listing with clear images, a complete title and reviews converts more of the clicks you pay for, which lowers your ACoS even at the same cost per click.
Cut the waste: review search term reports regularly, add negative keywords for searches that spend without selling, and move proven search terms into exact-match campaigns where you control the bid.
Bid by margin, not by habit. Products with a thin margin need a lower target ACoS than products with a fat one, so a single bid strategy across the catalog overpays on some and underinvests in others. Finally, judge success on ACoS against margin and on TACoS over time, not on cost per click alone.
