How do Amazon fee increases eat into my margin?

Answer · AgentXray team
Amazon fee increases affect your margin by lowering your break-even ACoS, which is the percentage of your sales price that you can spend on ads while still breaking even. When fees rise, your contribution margin decreases, making it harder to maintain profitability on your ad campaigns. For example, if your referral fee increases, it can silently push your break-even ACoS higher, meaning campaigns that were once profitable may now result in losses. This change is not reflected directly in your margin percentage, but rather in the reduced headroom for ad spending. To manage these impacts, it's essential to regularly check your fee estimates against actual charges and adjust your pricing and ad strategies accordingly.
