ACOS

Advertising Cost of Sale

ACOS (Advertising Cost of Sale) is the ratio of ad spend to ad-attributed intäkter on Amazon, expressed as a percentage. It measures the efficiency of your PPC campaigns by showing how much you spend on advertising for every dollar of sales generated through ads.

Why ACOS Matters for Amazon Sellers

ACOS directly determines whether your Amazon advertising is profitable. A lower ACOS means more efficient advertising spend, while a high ACOS can erode margins quickly. Understanding your target ACOS relative to your profit margin is essential for sustainable growth.

How RIDGE Analyzes ACOS

RIDGE reports include detailed ACOS benchmarking across competitors in your niche, historical ACOS trends, and recommended target ACOS ranges based on your unit economics. Our Monte Carlo simulation models ACOS variability to project realistic advertising profitability scenarios.

Practical Example

If you spend $25 on PPC ads and those ads generate $100 in sales, your ACOS is 25%. With a 35% profit margin before ad spend, this means 10% net margin after advertising.

Vanliga Frågor

What is a good ACOS on Amazon?+

A good ACOS depends on your profit margin. Generally, ACOS below your profit margin means profitable advertising. Most categories see average ACOS between 15-35%. New product launches may accept higher ACOS (40-60%) to gain visibility.

How is ACOS different from TACoS?+

ACOS only measures ad spend against ad-attributed sales. TACoS (Total Advertising Cost of Sale) measures ad spend against total sales (both organic and ad-driven), giving a more holistic view of advertising efficiency.
