Instantly Measure Your Advertising Profitability

Struggling to figure out if your ads are actually making you money on Amazon? Our Amazon ACOS Calculator helps you easily calculate your Advertising Cost of Sales (ACOS)—a critical metric to understand your PPC performance and profitability.

Whether you’re running Sponsored Products, Sponsored Brands, or Display Ads, this tool shows if you’re hitting profitable benchmarks.

What Is ACOS?

ACOS (Advertising Cost of Sales) = (Ad Spend ÷ Ad Revenue) × 100
It tells you how much you’re spending on ads to earn $1 in sales.

🧮 Example:
If you spend $25 and generate $100 in sales, your ACOS is 25%.

This calculator lets you go beyond the formula—factoring in product costs, profit margins, and breakeven points.
