Short on cash between grants, rent and study costs? A state SU loan can bridge the gap, but it adds debt you must manage after graduation. This guide tells you what the loan actually is, who can get it, and the concrete steps to apply and budget for repayment.

Key facts

SU loans are a state-backed student borrowing option administered alongside the SU grant.
You usually apply online with MitID and need a CPR number to receive payments.
Loan disbursements can often be chosen by month during your study year.
Repayment normally begins after you finish your education – check current rules before you borrow.
Compare with private loans and work options before committing; see alternatives below.

What is an SU loan?

SU (Statens Uddannelsesstøtte) is Denmark’s student support system. Most students already know the SU grant – a non-repayable allowance for eligible programmes. An SU loan is a separate, state-administered loan you can take while studying if the grant and other income are not enough.

The purpose is to give predictable, lower-cost student-focused borrowing compared with typical consumer loans. Terms, monthly caps and administrative details can change, so always verify on the official SU webpages before you decide.

Types of SU loans

SU lending commonly appears under a few forms in practice rather than tightly named products. Expect variations by education level (e.g. higher education vs vocational training) and personal circumstances.

Standard SU loan – a monthly top-up you add on top of any SU grant. Useful for spreading living costs over the study year.
Parental/extended components – some arrangements let parents participate (or affect the calculation) depending on your age and living situation. Details differ by case.
Final-year/top-up options – in some programmes you can apply for larger support in months with concentrated costs (project fees, thesis-related travel).

Names and availability change with regulations. Check the SU online system and your institution’s student service for what is offered to your specific programme.

Who is eligible for SU loans?

Eligibility depends on a mix of citizenship/residence, study programme and your enrolment status. Use these checkpoints to assess your likely position:

Danish citizens are usually eligible for SU grants and loans if you meet enrolment and residence requirements.
EU/EEA citizens living in Denmark under the right residence conditions often qualify, but some rules differ from Danish nationals.
Non-EU international students typically face stricter rules; many must demonstrate specific residence or work-permit conditions before qualifying.
You normally need a CPR number and an active student enrolment confirmation to receive payments.

If you are unsure how your visa or permit affects eligibility, check official guidance for your situation – for example, our explainer on work permit in Denmark can help clarify restrictions and allowable work hours that affect your funding mix.

Advantages of taking an SU loan

Lower cost and student-oriented terms – SU loans are typically cheaper and more flexible for students than high-interest quick loans, and the state structure is stable.
Flexible disbursement months – you can usually select which months to receive the loan (helpful if you only need cash during exam periods or summer housing gaps).
Simple online administration – apply and track balances via SU’s portal using MitID; changes to months and amounts are handled centrally.
Deferment while studying – repayment is deferred until after you finish your programme, so you don’t have to make payments during full-time study.

SU loan

State-backed, student-friendly options, deferred repayment, generally lower cost and controlled through SU’s system.

Private/quick loans

Fast access and fewer eligibility checks but higher interest, fees and less predictable repayment schedules – read the fine print carefully.

Warning: even though SU loans are designed for students, they are still debt. They can affect future borrowing ability and should be budgeted into your post-graduation plan.

Disadvantages and risks

Mandatory repayment – you will normally have to start repaying after you finish your education and meet any deadlines set by SU. Missing repayments can lead to collection actions.
Not always enough – SU loan monthly caps may still leave a gap in higher-cost cities or for international students with extra fees.
Eligibility can change – changes to residence status, programme transfer or study intensity can affect ongoing access to SU loans.
Processing time – initial approvals and changes can take time; if you wait until rent is due you risk a shortfall. Plan at least several weeks for documentation to be processed.

Alternatives to SU loans

Before you borrow, compare these options and their trade-offs:

Part-time work, student jobs or internships – check permitted hours for your permit and how extra income affects SU grant entitlement.
Private student or consumer loans – can fill gaps but compare APR, fees and repayment flexibility; see an overview of loan options in Denmark if you want a broader comparison.
Scholarships, grants, crowdfunding or family support – none require repayment and should be used first where possible.

Practical banking tip: make sure you have a Danish bank account and the correct IBAN format to receive SU payments; our guide to understanding IBAN in Denmark explains the details.

How to apply and practical steps

Get your documents ready: CPR number, confirmation of enrolment or student ID from your institution, and MitID for secure login.
Log in to the SU online portal and select the loan option you want; you can often choose which months to receive the loan during the academic year.
Enter your bank details (Danish IBAN recommended) and confirm how the loan and any grant payments will be split into months.
Save or screenshot approval letters and note the outstanding balance; SU provides an online overview of what you owe and payment history.
Build a repayment plan now: estimate how much you will owe on graduation and how it fits your expected income. Check whether you can defer or restructure payments in special circumstances.

Do not assume SU continues automatically each year – you may need to renew or re-confirm enrolment and update income information to keep grant or loan payments flowing.

Deciding if an SU loan is right for you

Use this short checklist to decide:

Can you cover basic costs without borrowing (rent, food, study materials)?
Will an SU loan amount plus part-time income and grants meet your monthly needs?
Are you prepared to start repaying after graduation and include that in your long-term budget?

If you still need options, compare the loan with other routes – our piece on other ways to finance your studies can help prioritise alternatives.

Do this first

Check your eligibility on the official SU site, gather your CPR and MitID, then log into the SU portal to see the exact monthly limits and repayment terms before applying.
