📚 Plan 5 Student Loan Overseas Repayment Thresholds by Country | 第五类学生贷款海外收入还款门槛按国家区分
Moving abroad does not switch off a Plan 5 student loan. It rewrites the rulebook. Plan 5, the repayment plan for English students who started full-time undergraduate courses on or after 1 August 2023, fixes the UK repayment threshold at £25,000 and charges 9% of everything earned above it over a 40-year term. The moment you live outside the UK for more than three months, the Student Loans Company (SLC) swaps the single UK threshold for a country-specific overseas threshold. Two borrowers on identical salaries in different countries can therefore owe completely different annual amounts.
搬到海外并不会让第五类学生贷款自动"关闭"，它只是改写了规则。第五类贷款适用于 2023 年 8 月 1 日及以后开始全日制本科课程的英格兰学生，英国本土还款门槛固定为 £25,000，超出部分按 9% 还款，还款期为 40 年。一旦你在英国境外居住超过三个月，学生贷款公司（SLC）就会用"按国家区分"的海外门槛取代单一的本土门槛。因此，两位薪资完全相同、但居住在不同国家的借款人，每年应还金额可能完全不同。
1. What Plan 5 Actually Is | 第五类学生贷款究竟是什么
Plan 5 is a repayment plan, not a type of loan product you choose. It is assigned automatically to English-domiciled students who began a full-time undergraduate course on or after 1 August 2023. Part-time and postgraduate borrowers have their own arrangements, and students from Scotland, Wales and Northern Ireland sit under different plans, so the country rules below apply specifically to Plan 5 borrowers.
第五类（Plan 5）是一种"还款计划"，而不是学生可以自行挑选的贷款产品。它自动分配给 2023 年 8 月 1 日及以后开始全日制本科课程的英格兰学生。非全日制与研究生借款人适用不同安排，苏格兰、威尔士和北爱尔兰学生也各自适用不同的还款计划，因此下文的国家区分规则专门针对第五类借款人。
The four numbers that define Plan 5 are: a £25,000 UK repayment threshold, a 9% repayment rate on income above that threshold, a 40-year repayment term before any remaining balance is written off, and an interest rate equal to the Retail Prices Index (RPI), which means there is no real interest rate on top of inflation.
定义第五类贷款的四个关键数字是：英国本土还款门槛 £25,000；超过门槛部分的还款比例为 9%；还款期为 40 年，到期后剩余余额被核销；利率等于零售物价指数（RPI），也就是说在通胀之外不再加收实际利率。
Crucially, the Plan 5 threshold is designed to stay at £25,000 and is not uprated each year in line with earnings or inflation. That single design choice is what makes the overseas threshold question so important: the gap between a frozen UK threshold and country-adjusted overseas thresholds grows wider over time.
关键之处在于，第五类贷款的门槛被设计为固定在 £25,000，不随收入或通胀逐年上调。正是这一设计，使得"海外门槛"问题格外重要：冻结的本土门槛与按国家调整的海外门槛之间的差距会逐年拉大。
2. The UK Threshold and the 9% Rule | 英国门槛与 9% 规则
UK, repayments are collected through PAYE, and the calculation is mechanical. You repay 9% of the difference between your gross annual income and £25,000. If you earn £25,000 or less, you repay nothing that year. If you earn £35,000, you repay 9% × £10,000 = £900 across the year, which is £75 a month.
在英国境内，还款通过 PAYE 工资系统代扣，计算方式非常机械：应还金额 = 9% ×（年收入总额 − £25,000）。若年收入不超过 £25,000，当年无需还款；若年收入为 £35,000，则应还 9% × £10,000 = £900，相当于每月 £75。
Annual repayment = 9% × (Gross annual income − Repayment threshold)
This formula is the same everywhere in the world. What changes when you move overseas is only the second term in the bracket. The threshold is no longer £25,000.
这个公式在全世界都成立。搬到海外后唯一改变的，是括号里的第二项——门槛不再是 £25,000。
Because the threshold is frozen while salaries normally rise with inflation, a Plan 5 borrower who stays in the UK on an average graduate salary will gradually repay a larger and larger share of income over the 40-year term. Overseas borrowers face a parallel effect, but through a different mechanism.
由于门槛被冻结，而薪资通常随通胀上涨，留在英国、拿着平均毕业生薪资的第五类借款人，在 40 年还款期内会逐渐偿还收入中越来越大的比例。海外借款人也会遇到类似效果，但作用机制不同。
3. Why the Threshold Changes When You Move Abroad | 为什么搬到海外后门槛会变
The overseas threshold exists to keep repayment fair in real terms. £25,000 buys very different amounts of food, rent and transport in London, Zurich and Lagos. If the SLC simply applied the UK threshold everywhere, borrowers in low-cost countries would be pushed into repayment far earlier in real terms, while borrowers in high-cost countries would effectively get a discount.
设立海外门槛的目的是让还款在实际购买力意义上保持公平。£25,000 在伦敦、苏黎世和拉各斯能买到的食物、房租和交通服务差别巨大。如果 SLC 在全球统一套用英国门槛，那么生活成本较低国家的借款人在实际意义上会更早被迫还款，而生活成本较高国家的借款人反而等于获得了折扣。
So the SLC publishes an overseas earnings threshold for each country and territory. Each threshold is derived from the UK threshold of £25,000, adjusted to reflect relative price levels in that country. The higher the cost of living, the higher the threshold; the lower the cost of living, the lower the threshold.
因此，SLC 会为每个国家和地区公布一个"海外收入门槛"。每个门槛都以英国本土的 £25,000 为基础，再根据该国的相对价格水平进行调整。生活成本越高，门槛越高；生活成本越低，门槛越低。
The practical consequence is the one that surprises borrowers most: working in a cheaper country does not necessarily mean repaying less. It means the bar you must clear before repaying anything at all is set lower.
由此产生的结果，往往最令借款人意外：在物价更低的国家工作，并不必然意味着还得更少——它意味着"开始需要还款的门槛线"被设得更低。
4. The Price-Level Method Behind the Numbers | 数字背后的价格水平方法
Although the SLC does not publish a single tidy formula for every territory, the underlying logic is a price-level or purchasing-power adjustment. You take the UK threshold, multiply it by an index representing the country's price level relative to the UK, and round the result to a sensible figure. The general shape is:
虽然 SLC 并未为每个地区公布一个统一整洁的公式，但其底层逻辑是"价格水平／购买力"调整：取英国门槛，乘以代表该国相对英国价格水平的指数，再把结果取整为便于使用的数字。基本形式是：
Overseas threshold ≈ £25,000 × (Country price level index ÷ 100)
If a country's price level index is 130 (prices 30% higher than the UK), the threshold lands near £32,500. If the index is 60 (prices 40% lower than the UK), the threshold lands near £15,000. The UK itself sits at index 100, which is why the domestic threshold remains £25,000.
如果某国价格水平指数为 130（物价高于英国 30%），门槛大致落在 £32,500；如果指数为 60（物价低于英国 40%），门槛大致落在 £15,000。英国本身指数为 100，因此本土门槛保持 £25,000。
Two practical warnings follow. First, the published thresholds are set administratively and are not simply "the exact index result"; SLC rounds and reviews them, so the real figure for your country must always be read from the official table for the correct plan and assessment year. Second, the table is updated periodically, so a figure you memorised two years ago may no longer be current.
由此有两点实务提醒。第一，公布的门槛是行政设定的，并不等于"指数算出的精确结果"；SLC 会取整并定期复核，所以你必须查阅对应计划、对应评估年度的官方表格。第二，表格会定期更新，两年前记住的数字可能已经过时。
5. Which Countries Sit High and Which Sit Low | 哪些国家门槛高、哪些国家门槛低
The pattern is broadly intuitive: high-income, high-cost economies receive the highest thresholds, while low-cost economies receive the lowest. The table below is an illustrative model built from the price-level method above, not a copy of the official SLC schedule. Use it to understand the direction and magnitude of the effect, then verify the actual number.
总体规律相当直观：高收入、高成本经济体获得最高门槛，低成本经济体获得最低门槛。下表中的数字是依据上文价格水平方法构建的"示例模型"，并非 SLC 官方表册的抄录。请用它来理解影响的方向与量级，然后务必核对真实数值。
| Country group | 国家类型 | Illustrative price index | 示例价格指数 | Illustrative Plan 5 threshold | 示例第五类门槛 |
| Switzerland, Norway | 瑞士、挪威 | 135–150 | ≈ £34,000 – £37,500 |
| Japan, Australia, Denmark | 日本、澳大利亚、丹麦 | 115–130 | ≈ £29,000 – £32,500 |
| United States, Germany, France | 美国、德国、法国 | 100–115 | ≈ £25,000 – £29,000 |
| China, Malaysia, Poland | 中国、马来西亚、波兰 | 55–75 | ≈ £14,000 – £19,000 |
| India, Nigeria, Vietnam | 印度、尼日利亚、越南 | 30–50 | ≈ £7,500 – £12,500 |
The takeaway is not the exact numbers but the spread. Across the world, the Plan 5 overseas threshold can plausibly range from roughly £8,000 to roughly £38,000 — a factor of nearly five. Two graduates with the same £40,000-equivalent salary would repay nothing in one country and thousands of pounds a year in another.
要点不在具体数字，而在差距之大。全球范围内，第五类海外门槛合理区间大致从 £8,000 到 £38,000，相差接近五倍。两位同样拿着相当于 £40,000 薪资的毕业生，在某个国家可能一分钱都不用还，在另一个国家则可能一年要还数千英镑。
Care should also be taken with territories that are not fully captured by price indices, such as offshore financial centres or countries with dual exchange rates. In these cases the published threshold may look anomalous relative to the local cost of living.
此外，对于价格指数难以完整覆盖的地区（例如离岸金融中心或存在双重汇率的国家）也需谨慎，这些地方公布的门槛相对于当地生活成本可能显得异常。
6. Currency Conversion and Assessment Dates | 货币换算与评估日期
Thresholds are published in pounds sterling, but most overseas borrowers are paid in local currency. Converting income correctly is therefore half the battle. The SLC specifies which exchange rate and which reference date to use for a given assessment year, and the figure is typically fixed rather than left to the borrower's discretion.
门槛以英镑公布，但大多数海外借款人领取的是当地货币，因此"正确换算收入"是成功的一半。SLC 会明确规定某一评估年度应采用哪个汇率、以哪一天为基准日，通常是固定数值，而非由借款人自行选择。
Do not use the rate that flatters you. If you convert at a rate that understates your sterling income, the assessment will be wrong, and corrections usually cost more time than doing it properly the first time. Keep the source of the rate you used, for example a central bank reference rate or the rate stated on the SLC form.
不要选用对自己有利的汇率。如果换算后的英镑收入被低估，评估结果就是错误的，而事后更正的代价通常远高于一次性做对。请保留你所使用汇率的来源，例如央行参考汇率，或 SLC 表格上载明的汇率。
Where income fluctuates — freelance work, commission, overseas bonuses — the assessment generally looks at total income for the relevant period rather than a single month. Bonus timing can therefore shift a borrower above or below the threshold for a whole year, so plan contract and payment dates with the assessment period in mind.
当收入波动较大时——自由职业、佣金、海外奖金——评估通常看相关期间的总收入，而不是某一个月。奖金的发放时点因此可能把借款人推到门槛之上或之下，从而影响整年的还款，所以应结合评估周期来安排合同与付款时间。
7. Worked Calculation: Three Borrowers, One Salary | 例题演算：三位借款人，同一份薪资
Assume three Plan 5 borrowers each earn the equivalent of £42,000 a year, but live in different places. Borrower A stays in the UK, Borrower B lives in a country with an index of 140, and Borrower C lives in a country with an index of 60.
假设三位第五类借款人年收入都相当于 £42,000，但居住地不同：A 留在英国，B 居住在价格指数为 140 的国家，C 居住在价格指数为 60 的国家。
Borrower A: threshold £25,000 → 9% × (£42,000 − £25,000) = £1,530
Borrower B: threshold £35,000 → 9% × (£42,000 − £35,000) = £630
Borrower C: threshold £15,000 → 9% × (£42,000 − £15,000) = £2,430
The spread is £1,800 a year between the highest and lowest case, on identical nominal income. Borrower C, in the cheapest country, pays the most in sterling terms, because the threshold there is lowest. This is the single most counter-intuitive result in the whole overseas system.
在同一名义收入下，最高与最低情形之间相差每年 £1,800。生活在物价最低国家的 C，用英镑计算反而还得最多，因为当地门槛最低。这是整个海外还款体系中最反直觉的一点。
Monthly equivalents make the difference easier to grasp: A pays about £127.50, B about £52.50, and C about £202.50. Overseas repayments are normally collected in monthly instalments by Direct Debit, or as an annual lump sum if the borrower prefers.
换成月供更直观：A 每月约 £127.50，B 约 £52.50，C 约 £202.50。海外还款通常通过直接借记按月收取，借款人也可以选择一次性年度支付。
8. Evidence You Must Provide | 必须提供的收入证明
Overseas repayment is self-declared and then verified. The SLC issues an overseas income assessment form, and the borrower must return it with supporting evidence by the stated deadline. Missing the deadline is treated as non-cooperation rather than as having no income.
海外还款采取"自我申报 + 事后核验"的方式。SLC 会寄出海外收入评估表，借款人必须在规定期限前连同证明材料一并交回。逾期未交会被视为"不配合"，而不是"没有收入"。
Acceptable evidence commonly includes a local tax return or tax assessment notice, an employer letter stating gross annual salary, payslips covering the relevant period, and — for the self-employed — accounts or a tax computation. Documents in a foreign language normally need a certified English translation.
可接受的证明材料通常包括：当地纳税申报表或税务评估通知、注明年度税前薪资的雇主信函、涵盖相关期间的工资
