Break-even ACOS (Advertising Cost of Sale) is the maximum percentage of advertising spend relative to sales where you neither make nor lose money. It's calculated using the formula: Break-even ACOS = (Selling Price - Product Cost - Amazon Fees) / Selling Price × 100. This is your maximum allowed ACOS to maintain profitability.
To calculate break-even ACOS, use this formula: Break-even ACOS = Profit Margin × 100. For example, if your product costs $10, sells for $25, and has $5 in fees, your profit margin is 40% ($10/$25), making your break-even ACOS 40%. Our calculator automates this process and includes all relevant Amazon fees.
A good ACOS should be below your break-even ACOS to ensure profitability. While average ACOS varies by category (typically 15-40%), your target should be based on your specific product margins and business goals. Use our calculator to determine your optimal ACOS target.
To lower your ACOS: 1) Optimize your product listings for better conversion rates, 2) Use negative keywords to eliminate wasteful spend, 3) Focus on high-performing search terms, 4) Adjust bids based on your break-even ACOS, and 5) Improve product pricing strategy. Our calculator helps determine your target ACOS for optimization.
