退税计算器
按国家选税率，估算海外购物的可退税额，出境买买买心里有数。
可退税额 = 金额 × 通常退税率；实际以退税公司（Global Blue / Planet 等）费率、起退金额与商品类别为准。
中文介绍
在欧洲、日本、韩国等地购物，外国游客通常能退还一部分增值税/消费税。这个工具按国家带入标准税率与通常退税率，快速估算你能拿回多少。
注意：实际到手金额会因退税公司手续费、起退门槛、商品类别而变，本工具给的是常见口径的估算值。
常见问题
为什么退税率比税率低？
因为退税公司（Global Blue、Planet 等）会收手续费，且部分商品不退全额税，所以实际退税率通常低于名义税率。
有最低消费要求吗？
多数国家有起退金额（如欧盟各国 25–175 欧元不等、日本同店 5000 日元），低于门槛不能退。
怎么办理退税？
购物时索要退税单并带护照，离境时在机场海关盖章/核验，再在退税点取现金或退到卡。
English
In Europe, Japan, South Korea and elsewhere, foreign visitors can usually reclaim part of the VAT/GST. This tool applies a country's standard rate and typical refund rate to estimate how much you can get back.
Note: the actual amount varies with refund-company fees, minimum spend and product category — this gives a common, ballpark figure.
FAQ
Why is the refund rate lower than the tax rate?
Refund companies (Global Blue, Planet, etc.) charge fees, and some goods don't refund full tax, so the real refund rate is usually below the nominal rate.
Is there a minimum spend?
Most countries have a threshold (e.g. EU countries 25–175 EUR, Japan 5000 JPY in one store). Below it you can't claim.
How do I claim a refund?
Ask for a tax-refund form with your passport at purchase, get it stamped/verified at the airport customs, then collect cash or refund to your card.
