What is Amazon ACoS?

ACoS measures the performance of your Amazon PPC campaigns. Learn the break-even ACoS formula and what a good ACoS looks like.

Definition

ACoS, or Advertising Cost of Sales, is a key metric used on Amazon to measure the performance of your Sponsored Products campaigns. It indicates the ratio of ad spend to targeted sales.

People Also Ask: How do you calculate ACoS?

The ACoS Formula is: ACoS = (Total Ad Spend / Total Ad Sales) x 100 For example, if you spend $20 on PPC ads and generate $100 in sales, your ACoS is 20%.

People Also Ask: What is a “good” ACoS on Amazon?

A good ACoS depends heavily on your profit margin.

  • Break-even ACoS: The point where your ad spend equals your profit margin. If your profit margin is 30%, a 30% ACoS means you break even.
  • Target ACoS (TACoS): A lower ACoS means the campaign is profitable. For most established sellers, an ACoS between 15% and 25% is considered healthy and profitable.

People Also Ask: What is the difference between ACoS and ROAS?

ACoS (Advertising Cost of Sales) and ROAS (Return on Ad Spend) are inverse metrics. ACoS measures spend as a percentage of sales (e.g., 20%). ROAS measures the multiplier of return (e.g., a 20% ACoS is equivalent to a 5.0 ROAS, meaning you make $5 for every $1 spent).

How do I lower my ACoS?

To lower your Amazon ACoS, focus on adding negative keywords, optimizing your bids based on placement, improving your product listing conversion rate, and targeting long-tail keywords with lower CPCs.
