Shopify storefronts typically pay card fees through Shopify Payments. On the US Basic plan, online rates are often cited near 2.9% + $0.30 per successful charge; Shopify and Advanced plans frequently quote slightly lower percentages. Third-party gateways may add an extra Shopify fee on top of the processor.

Your monthly subscription is separate. This calculator lets you assign an optional “plan share per order” (for example $39/mo ÷ expected orders) so contribution profit reflects both variable and fixed costs.

Apps, themes, and shipping insurance are outside this model. Use it to compare list price versus COGS before you scale ads.

If you also sell on Etsy, TagPeek’s pre-publish check catches photo and tag issues that fee calculators never see.

Shopify 店铺通常通过平台自带的收款通道支付卡费。美国入门套餐线上费率常约为 2.9% + 0.30 美元；更高套餐百分比往往略低。第三方网关可能在处理费之外再加店面费用。

店铺月费另计。本计算器可填写可选的「每单月费分摊」（例如每月 39 美元 ÷ 预计单量），让贡献利润同时反映变动与固定成本。

应用、主题与运费险不在模型内。用来对比标价与成本，再决定是否加广告。

若也在 Etsy 销售，用 TagPeek 的 发布前体检抓住费用计算器看不到的图片与标签问题。
