What is a good CPC on Amazon?

A good CPC is one at or below the maximum your product can afford, which is order value times conversion rate times target ACoS. For context, a 2026 WisePPC dataset of US accounts found a median of $0.82, with most between $0.51 and $1.22.

How is CPC calculated on Amazon?

In reports, CPC is total spend divided by total clicks. In each auction, Amazon ranks ads on relevance and bid. Amazon describes the price as set by a second-price auction with reserve prices, and says advertisers never pay more than their bid.

Why is my Amazon CPC so high?

Common causes are heavy competition on the keyword, seasonal peaks, large top of search placement adjustments, dynamic bids up and down, and low relevance between your listing and the search. Check the placement report and search term report to see which applies.

Does Amazon charge my full bid?

Amazon says you never pay more than your bid and that, when a bid clears its soft reserve, you pay that reserve. The FTC alleges advertisers paid their full bid about 80% of the time by 2024. Amazon disputes this, and the case has not been decided.

How can I lower my CPC on Amazon?

Improve relevance by putting the keyword in your title, Item Highlights and bullets, and improve conversion with better images and reviews. Then shift spend to exact and long-tail terms, use dynamic bids down only for discovery and trim placement adjustments that do not pay back.

What does CPC mean on Amazon?

CPC is cost per click. In reports it is total spend divided by total clicks, so it is an average across many auctions, not one price. Your bid is the maximum you are willing to pay for a click, and Amazon says you never pay more than it. CPC on its own says little: a $2.00 click that converts at 20% costs less per order than a $0.80 click that converts at 5%. That is why CPC should always be read with conversion rate and ACoS. Our Amazon advertising metrics guide shows how they fit together.

How the Amazon ad auction sets your CPC

Amazon describes its sponsored ads auction as a generalized second-price auction, used since 2006. Ads are ranked on relevance and bid together, so the highest bid does not always win. Amazon says about 92% of the ads it selected in 2024 were not the highest bid. In a classic second-price auction the winner pays just above the next price needed to win, not their own bid.

Amazon also uses reserve prices. In its own description, a hard reserve is the minimum a bid must clear to enter the auction, and a soft reserve is Amazon's estimate of what a placement is worth. If your bid clears both, you pay the soft reserve; if it clears only the hard reserve, you pay your bid. In every case Amazon says you pay no more than your bid.

Why Amazon's CPC pricing is in court

On August 31, 2026, the FTC and 22 state attorneys general sued Amazon in federal court in Washington. They allege Amazon told advertisers the winner pays one cent more than the next highest bidder, but from 2019 added an undisclosed soft reserve price that raised prices. The complaint says Sponsored Products advertisers paid their full bid 30% to 40% of the time in 2021, 70% in 2022 and about 80% in 2024. Amazon calls the suit misguided, says reserve prices are standard, and says relevance-based ranking saved advertisers an estimated $8 billion from 2021 to 2025. The claims are allegations and have not been decided.

For your account, the takeaway is practical: treat your bid as the price you are likely to pay, especially on competitive terms, and set it from your economics.

Amazon CPC benchmarks in 2026

WisePPC published a dataset on June 30, 2026, covering 19 US accounts from April 1 to June 29, 2026: median CPC $0.82, with the middle half of accounts between $0.51 and $1.22. These accounts all used an optimization tool, so they are not a random sample. Expect higher CPC in crowded, high-price categories and during Q4 and deal events, and lower CPC on long-tail and branded terms. Our guide to how much Amazon advertising costs turns this into a budget.

How to calculate your maximum CPC

Your maximum affordable CPC is the most a click can cost before the ad sale stops making the profit you want. The formula is average order value times conversion rate times target ACoS. Target ACoS comes from margin: break-even ACoS equals profit margin before ads, and target sits below it. Our guide to a good ACoS for Amazon covers the margin calculation.

Illustrative example: a $35 product with a 12% conversion rate and a 25% target ACoS supports a max CPC of $35 x 0.12 x 0.25, about $1.05. At 6% conversion the same target supports only about $0.53. If you use dynamic bids up and down, Amazon can raise bids by up to 100% on some clicks, so either enter a lower base bid or use down only.

Max CPC = order value x conversion rate x target ACoS
Break-even ACoS = margin before ad spend
Lower conversion means a lower affordable CPC

Max CPC at a 25% target ACoS (illustrative)

	6% conversion	12% conversion
$20 order	$0.30	$0.60
$35 order	$0.53	$1.05
$60 order	$0.90	$1.80

What makes CPC go up?

Several forces push click prices up, and most are visible in your reports.

More advertisers bidding on the same keyword
Seasonal peaks such as Q4, Prime Day and deal events
Top of search placement adjustments of up to 900%
Dynamic bids up and down raising bids on likely buyers
Low relevance, which forces a higher bid to win

How to lower your Amazon CPC, step by step

Lower CPC only matters if cost per order falls too. Work through these in order, and see Amazon PPC bidding strategies and how to optimize Amazon PPC for detail.

Improve relevance: keyword in title, Item Highlights and bullets
Raise conversion: images, reviews, price and A+ Content
Shift spend to exact match and long-tail terms
Use dynamic bids down only on discovery campaigns
Trim placement adjustments that do not pay back
Add negatives for terms with clicks and no orders
Review CPC by hour and cut costly, low-converting hours

Is a low CPC always better?

No. Very low CPC often means you are only winning cheap, low-intent placements or long-tail terms with little volume. The bigger category keywords cost more because they sell more. If your ACoS is well below break-even and total sales are flat, raising bids on profitable category terms can grow sales and profit even as CPC rises. Watch TACoS to see whether ads are growing the whole business; our ACoS vs TACoS guide explains how.
