Amazon sellers usually pay a referral fee that depends on category — commonly in the 8–15% range — plus FBA fulfillment fees that scale with size tier and shipping weight. This tool defaults referral to 15% (conservative) and applies a simplified per-pound fulfillment model so you can stress-test landing prices quickly.

Real FBA invoices also include storage, long-term storage, returns processing, and inbound placement options. Treat the number here as a planning floor, not an Amazon Business Report substitute.

Change the referral percentage to match your category’s public fee schedule, and adjust weight toward your packed unit. Then compare pocket profit against ads and returns you expect.

Amazon 卖家通常支付按类目的佣金（referral）——常见 8–15%——外加随尺寸档与重量变化的 FBA 履单费。本工具默认佣金 15%（偏保守），并用简化的按磅履单模型，方便快速压测定价。

真实账单还有仓储、长期仓储、退货处理与入库选项等。这里的数字是规划下限，不能替代后台报表。

按类目官方费率改佣金百分比，并按打包重量调整，再对照广告与退货预期看到手利润。
