What is Amazon PPC Break Even Point?
The break even point is the maximum ACoS percentage your product can sustain without losing money. ACoS stands for Advertising Cost of Sale — it measures how much of your revenue goes toward ad spend.
If your break even ACoS is 30%, your campaigns must stay below 30% to remain profitable. At exactly 30%, you break even. Above 30%, every sale through ads costs you money.
- Understand the maximum safe advertising percentage per product

Amazon PPC Break Even Formula Explained
The calculator uses one simple formula. Break Even ACoS equals the profit margin before advertising.
Formula
Break Even ACoS =
((Selling Price − Total Costs) ÷ Selling Price) × 100
Worked Example
Selling Price = ₹1,000
Total Costs Before Ads = ₹700
Profit Before Ads = ₹300
Break Even ACoS = (300 ÷ 1000) × 100 = 30%
This means your advertising spend must stay below 30% of your revenue. At 30%, ad spend exactly consumes all available profit.
