Current ACOS is below break-even — ads are still profitable.
- Duty and clearance are excluded, so real profit will be lower. The US $800 de minimis exemption no longer applies.
- No platform fees were applied, so this profit excludes commission and fulfilment fees. Add your own rates or override the total.

All platform fee rates, duty rates and freight rates in this tool are configurable placeholders. They are not verified official rates and must be confirmed against the platform seller centre, the HTS/CBP schedules and your own freight forwarder before you rely on them.
Break-even ACOS is the profit left before advertising, divided by the selling price. Everything upstream of it changes the answer — goods cost, freight, duty, commission, returns — which is why an ACOS target copied from a category benchmark is usually wrong for your unit. Enter your real costs and the calculator gives you the ceiling, the equivalent ROAS, and a clear statement of whether your current ACOS sits under it.
