Amazon revises fee schedules at least annually and adds new surcharges more often. These defaults are a starting point — the figures in your own fee preview are the ones that describe your ASINs.

Cost per acquisition is $8.55, which is cost per click divided by conversion rate. Improving the listing so conversion rises from 11% to 13.2% would cut it to $7.12 without touching a single bid.

How the Amazon Advertising Cost Calculator works

Cost per acquisition is cost per click divided by conversion rate — which means the listing does more for your ad costs than the bids do. Improving conversion from 10% to 12% cuts acquisition cost by a sixth without touching a single bid.

Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price — check the platform's current fee schedule before you price a product against it. This is not tax or business advice.

Frequently asked questions

How do I estimate Amazon ad spend?

Impressions times click-through rate gives clicks; clicks times cost per click gives spend; clicks times conversion rate gives orders. Spend divided by orders is your cost per acquisition.

What is a typical CPC on Amazon?

It varies enormously by category — under 50 cents in some niches, several dollars in competitive supplements or electronics. Your own search term report is the only reliable source.

How do I lower cost per acquisition?

Improve conversion rate first: better main image, clearer title, more review volume, competitive price. Conversion improvements compound across every keyword, whereas bid changes only affect the one.

Should I bid on my own brand?

Usually yes, defensively — if you do not, a competitor will appear above your own listing. It looks like paying for sales you would have had, and partly it is, but the alternative is worse.
