Amazon PPC bid calculator

Your max cost per click from price, CVR and ACoS.

Quick answer

Max CPC = price × conversion rate × target ACoS. A 2 850 ₽ item at 10% CVR and 25% target ACoS supports bids up to 71 ₽ per click.

Start from an example:

Product

$
%
Price minus product cost and Amazon fees, as % of price. This is your break-even ACoS.

Ads

Orders ÷ clicks for the keyword or campaign.

Average cost per click you pay now.

Estimate. Use conversion rate and CPC for the same keyword or campaign and date range.

How the max PPC bid is calculated

  • Revenue per click

    price × conversion rate

    What each click is worth in sales. At 2 850 ₽ and 10% CVR, each click brings in 285 ₽ on average.

  • Max CPC

    price × conversion rate × target ACoS

    The most you can pay per click and still hit your target ACoS.

  • Break-even CPC

    price × conversion rate × margin before ads

    Above this bid, every ad sale loses money.

Frequently asked questions

What should I bid on Amazon PPC?

Start at or a little below your max CPC from this calculator, then adjust each keyword by its own conversion rate after a week or two of data.

Why is my actual ACoS higher than my target?

Your real conversion rate or CPC differs from the inputs. Re-run the numbers with the keyword’s actual CVR and average CPC.

Is the bid the same as what I pay?

No. Your bid is the most you are willing to pay. The CPC you pay is often lower, set by the auction.

What conversion rate should I use for a new product?

Use a cautious guess, such as 5–10%, then replace it with real data once you have 100+ clicks.
