跨境汇款的成本有三块：明面手续费、汇率点差、中间行扣费。人们只盯着第一块，而通常最大的是第二块——银行给你的牌价和当时的中间价之间那几个百分点，不写在任何一张单据上。 这里去公开接口取实时中间价（欧洲央行参考汇率，取不到时用备用源），把你拿到的牌价和它一比，点差换算成钱直接摆出来。再加上手续费和中间行扣费，算出这笔汇款的全部成本占多少。 还有四个汇款前该问的问题，其中「费用是 OUR / SHA / BEN 哪一种」这一条，选错了收款人少收的钱可能比手续费还多，而多数人从没被告知过有这个选项。$2 解锁多路径成本对比、中间行扣费的常见坑、汇款用途与申报要点，以及汇款单填写自查。A cross-border transfer costs you in three places: the stated fee, the exchange-rate spread, and intermediary bank deductions. People watch the first; the largest is usually the second — the few percent between the rate you're quoted and the mid-market rate at that moment, which appears on no receipt. This pulls the live mid-market rate from a public source and puts your quoted rate next to it, converting the spread into money. Add the fees and the expected intermediary deduction and you get the true total cost as a percentage. Plus the four questions to ask before sending — including whether the charges are OUR, SHA or BEN, where the wrong choice can cost the recipient more than the fee itself, and which most senders are never told about. $2 unlocks a multi-route cost comparison, the intermediary-deduction traps, purpose and reporting notes, and a form-filling check.
多路径成本对比表（银行电汇 / 第三方汇款 / 分笔 / 收款方所在地开户）+ 中间行扣费与收款行手续费的常见坑 + 汇款用途与申报要点清单 + 汇款单逐栏填写自查（填错会被退汇）。A cost comparison across routes (bank wire, transfer services, splitting, an account at the destination), the intermediary and beneficiary-bank traps, purpose and reporting notes, and a field-by-field check of the transfer form.
中间价来自公开汇率接口，为参考基准而非可成交价格，与你实际成交时点的价格会有差异。计算只包含你输入的项目；中间行扣费不事先告知、金额不确定，本工具用你填的预估值计算。本工具不是金融或税务建议，不推荐任何银行或汇款服务，也不涉及外汇管理规定的合规判断——跨境汇款的额度、用途与申报要求按你所在地与目的地的现行规定，请以银行和监管机构的说明为准。你填写的内容不入库。The mid-market rate comes from a public feed as a reference benchmark, not a dealable price, and will differ from your actual execution. The calculation includes only what you enter; intermediary deductions are not disclosed in advance and are estimated from your input. This is not financial or tax advice, recommends no bank or service, and makes no compliance assessment — limits, permitted purposes and reporting obligations follow the rules where you and the recipient are, per your bank and regulator. Nothing you enter is stored.
