Student loans worldwide: four models and who carries risk

Student loan systems differ between countries in ways that make headline figures incomparable. Two countries can both report an average debt on graduation and mean entirely different things, because the repayment terms, the interest convention and what happens to an unpaid balance are decided separately in each.

The useful question is not how large the balance is but what the repayment obligation looks like if your income is low, because that is the circumstance in which a loan system either protects you or does not.

Quick answer

Compare systems on the repayment mechanism, not the balance. The three things that decide whether a loan is manageable are whether repayment is tied to income, what happens to an unpaid balance after a defined period, and whether interest accrues faster than a low income can reduce it.

What actually differs between countries

• Income-contingent repayment. Payments are a proportion of earnings above a threshold, so a low income produces a small or zero payment. This is the feature that makes a large balance survivable.
• Mortgage-style repayment. A fixed schedule regardless of income, which makes the same balance considerably more dangerous at a low income.
• Interest convention. Whether interest is charged from disbursement or from graduation, whether it is subsidised while studying, and whether the rate is fixed or linked to an index.
• The write-off rule. Whether an unpaid balance is forgiven after a defined period, and how long that period is. This is the term that decides what the balance actually costs over a lifetime.

The evidence on how long study actually takes

The OECD’s Education at a Glance 2024 reports that only 43 per cent of new entrants to bachelor’s programmes across reporting countries graduate within the expected duration, rising to 59 per cent a year later and 70 per cent after three additional years. A loan term that assumes on-time completion assumes something that happens to fewer than half of students, and the cost of an extra year is usually the part people did not plan for.

This matters for loan planning specifically. An extra year is an extra year of fees and living costs, and often a year of reduced earning. A repayment plan built on the expected duration is built on a minority outcome.

The questions to ask about any system

1. Is repayment tied to income, and above what threshold?
2. What interest applies, from when, and is it subsidised during study?
3. What happens if I move abroad, and is the obligation enforced across borders?
4. Is there a write-off, after how long, and what conditions attach to it?
5. Can the terms be changed after I have borrowed, and by whom?

The last question is the one students rarely ask and the one most likely to matter over a long repayment period. Terms set in legislation can be changed by the body that set them, and the protection available to you depends on whether the change applies to existing borrowers.

What this page cannot tell you

The specific figures, thresholds and write-off periods are set by each country’s government and change with legislation and with annual announcements. They are published by the body that administers the loan in that country, and that is where the current position must be checked — not from a comparison page, and not from a figure remembered from a previous year.

Where you are considering a system you do not live in, the same questions are addressed to the administering body in that jurisdiction. In the Philippines, the relevant programme is administered by UniFAST; in the United Kingdom, by the Student Loans Company; in the United States, by the federal student aid office. Each publishes its own current terms.

How a repayment fits within a monthly budget is in how to budget as a student. Where a repayment has become unmanageable, the position is covered in debt problems and what to do.

What the balance on graduation does not tell you

An average debt figure is reported in most countries and is almost meaningless on its own. It mixes students who borrowed for tuition with those who borrowed for living costs, it mixes short programmes with long ones, and it describes an amount owed rather than an amount that will actually be repaid.

Where repayment is income-contingent and an unpaid balance is written off after a defined period, many borrowers never repay the whole balance, and the amount forgiven is a deliberate part of the design rather than a failure. In that system the balance is a starting figure for a calculation, not a debt in the ordinary sense.

This is why a country with high reported balances and income-contingent terms can be less risky for a graduate on a low income than a country with lower balances and fixed schedules. The comparison must be of the repayment mechanism.

If you are considering studying in another country

Three questions decide most of the risk, and all three are answered by the body that administers the loan rather than by the institution you are applying to.

1. Can I borrow at all, and does eligibility depend on nationality or residence?
2. What are the repayment terms if I leave the country after graduating, and are they enforced across borders?
3. What happens to the obligation if I cannot work, or my income stays low?

The second is the one students most often overlook. An income-contingent system that depends on a domestic tax authority may not track an income earned elsewhere, and the consequence is either an obligation that cannot be assessed or one that is enforced on different terms.
