The Hidden Debt Behind Your Student Loan (UK)

The maintenance loan lands in one lump, and by week eight it is a memory. What carries you to the next one is rarely the loan.

What the 2026 survey found

Two cautions from our reading. The page describes the 23% as among those with overdrafts in one place, but the body text applies it to the 25% who were overdrawn when they responded, and it does not say which base is right. Its credit card figure is also inconsistent: the infographic caption says 17% have credit card debt, while the text says almost one in 20. We have left the credit card number out.

The part nobody explains: the day the interest-free period ends

Experian says student overdrafts usually carry 0% interest while you study, the account usually switches to a graduate account afterwards, and that can stay interest-free for about a year before limits come down (Experian). Its advice is to make a repayment plan, treat each limit reduction as a milestone, and ask your bank about repayment options. Run your own numbers with our Klarna, Clearpay and PayPal comparison and the BNPL calculator below before you add a fourth instalment plan.

A short checklist before graduation

1. Find your overdraft limit and the date your bank says the interest-free period ends.
2. List every BNPL plan with the next payment date.
3. Set up a standing order from your first salary towards the overdraft.
4. If the numbers do not work, speak to a free adviser before missing a payment.

Straight answers to the follow-ups

How many students use buy now, pay later?

Save the Student’s 2026 banking survey found 29% use BNPL at least some of the time, including 9% who use it often, against 27% last year. The survey had 845 responses, collected 23 March to 12 May 2026 (Save the Student).

How big is the gap between the maintenance loan and living costs?

The survey page cites an average shortfall of £502 a month, taken from the separate National Student Money Survey 2025 (Save the Student). It is a survey average, not a figure for your course or city.

Do student overdrafts cost anything while I study?

Student overdrafts usually carry 0% interest during your degree, but the balance still has to be repaid, according to Experian (Experian).

What happens to my overdraft when I graduate?

Experian says the account usually switches to a graduate account that may stay interest-free for about a year, and that some banks then lower the interest-free limit gradually, with interest charged on anything above it, usually at a high rate (Experian). Our guide to old graduate overdrafts and statute barred debt covers what happens if one is left for years.

Do students know when the overdraft has to be repaid?

Often not. Save the Student reports that 41% of students do not know when their overdraft must be repaid (Save the Student).

Do student loans show on my credit report?

Experian says student loans do not appear on your credit report and do not affect your score (Experian). Experian says an overdraft can affect your score: heavy use over a long period may lower it, while using a little and repaying quickly shouldn’t harm it.

What if I am already behind on a BNPL payment?

Late BNPL payments are described by Save the Student as concerning given the fees involved (Save the Student). Our missed Klarna or Clearpay payment guide covers what usually follows.
