Here’s how to find out.
You need to calculate your Break-Even ACoS (Advertising Cost of Sales).
It’s the tipping point between profit and loss for your campaign.
How to calculate it:
- Take your product sales price
- Subtract the total landed cost — this includes product cost, shipping, and all Amazon fees
- Divide the result by your product sales price
That gives you your Break-Even ACoS (%)
This is the maximum ACoS you can afford while still breaking even.
If your ACoS goes above that number → you’re losing money.
If it’s below → you’re running profitably.
It’s a simple formula, but most sellers ignore it — and bleed cash through ads that look good on the surface but don’t actually return profit.
Know your numbers. Run smarter campaigns.
