10 Student Loan Myths Debunked — Common Misconceptions

Myth 1: "I Repay 9% of My Whole Salary"

This is probably the most widespread misunderstanding about student loans, and it causes enormous unnecessary anxiety. The truth is you repay 9% only of the amount you earn above the repayment threshold — not 9% of your entire salary.

Let's use a concrete example. If you're on Plan 2 with a repayment threshold of £29,385 and you earn £35,000, you repay 9% of the difference: 9% × (£35,000 − £29,385) = 9% × £5,615 = £505.35 per year, or about £42 per month. That's very different from 9% × £35,000 = £3,150 per year (£262.50 per month), which is what many people fear they'll pay.

The system works identically to income tax. You don't pay 20% income tax on your whole salary — you pay it on earnings above the personal allowance. Student loan repayments follow exactly the same principle. If you earn below the threshold, you pay nothing at all.

Myth 2: "Student Loans Affect My Credit Score"

They don't. UK student loans do not appear on your credit report. They are not recorded by any of the three main credit reference agencies (Experian, Equifax, or TransUnion). No lender can see your student loan balance when they check your credit file. Your student loan cannot cause you to fail a credit check.

However, there is a nuance. While student loans don't affect your credit score, mortgage lenders will take your student loan repayments into account when assessing affordability. Because repayments reduce your monthly take-home pay, lenders may offer you a slightly smaller mortgage than they would if you had no student loan. This isn't a credit score issue — it's an affordability assessment, which is a different thing entirely. The loan itself is invisible to the credit system.

Myth 3: "I Should Pay It Off as Soon as Possible"

This is perhaps the most financially damaging myth. The instinct to clear debt quickly is understandable — it's good advice for credit cards and personal loans. But student loans are fundamentally different.

The key question is whether you'll repay the full balance before the write-off date. Government estimates suggest that around 70–80% of Plan 2 borrowers will still have a balance remaining when their loan is written off after 30 years. For these borrowers, any voluntary overpayment is money thrown away — they'd never have had to pay it under the normal repayment schedule because the remaining balance would have been cancelled anyway.

Only consider overpaying if you've used a student loan repayment calculator and confirmed that you'll repay in full before write-off. Even then, compare the interest saved with what you could earn by investing the money instead. Read our repayment strategies guide for a detailed framework.

Myth 4: "The High Interest Rate Means I Pay More"

This myth confuses how student loans work with how commercial loans work. On a mortgage, the interest rate directly determines how much you pay in total. On a student loan, the interest rate is largely irrelevant for most borrowers.

Why? Because your total repayments are determined by your income over the repayment period, not by your balance or interest rate. If you're in the majority who won't clear the balance before write-off, the interest rate simply determines how fast your unrepaid balance grows — but that balance is going to be written off anyway. Whether your written-off balance is £20,000 or £40,000 makes absolutely no difference to you.

The interest rate only matters if you're a high earner who will repay in full. For that group, higher interest means paying more in total. But for most graduates, a high interest rate is psychologically distressing but financially irrelevant. As we explain in our graduate tax comparison, this is because the loan functions like a tax, not a debt.

Myth 5: "I'll Be in Debt Forever"

No, you won't. Every student loan plan has a defined write-off date. Plan 1 loans (post-2006 borrowers) are written off after 25 years. Plan 2 loans are written off after 30 years. Plan 4 (Scotland) loans are written off after 30 years. Plan 5 loans are written off after 40 years. Postgraduate loans are written off after 30 years.

After the write-off date, any remaining balance is cancelled completely. You owe nothing more. The deductions from your salary stop. It's over. The write-off is automatic — you don't need to apply for it or take any action. The SLC will simply stop collecting.

Even before write-off, if your income drops below the threshold at any point — due to career changes, part-time work, taking time off, or any other reason — your repayments pause automatically. You're never trapped.

Myth 6: "I Shouldn't Go to University Because of the Debt"

This myth has a real and measurable impact: research shows that debt-averse students, particularly from lower-income backgrounds, are deterred from attending university by headlines about £50,000+ student loan balances. This is tragic because it's based on a fundamental misunderstanding.

The headline balance is not what you pay. Most graduates pay back far less than they borrow. Whether you borrow £30,000 or £50,000 typically makes no difference to your total repayments, because you'll never repay it all anyway. What determines your repayments is your income after graduation, not your loan balance.

Meanwhile, the evidence on the graduate premium — the extra lifetime earnings from having a degree — remains strong. On average, graduates earn around £10,000 more per year than non-graduates over their careers. Even after accounting for student loan repayments, university is financially worthwhile for the vast majority of students. The cost of not going to university is often far greater than the cost of the loan.

Myth 7: "My Balance Is What I'll Pay"

When you check your student loan balance and see a figure like £45,000, it's natural to think "I need to repay £45,000." But for most graduates, the balance is a meaningless number. It's like the sticker price on a car that everyone knows will be discounted — except in this case, the "discount" could be 50% or more.

Your actual total repayments depend entirely on your income trajectory over the repayment period. A graduate earning £30,000 with Plan 2 would repay around £55 per year (9% × £615 above threshold). Over 30 years, even with salary growth, many would repay far less than their original balance. The balance on your statement is the notional amount owed — it's not a prediction of what you'll actually pay.

Use our calculator to see your projected total repayments based on your actual salary. For many people, the figure is surprisingly affordable.

Myth 8: "Earning More Means Losing Money to Loan Repayments"

Some people worry that getting a pay rise is pointless because "it'll all go on student loan repayments." This is wrong and reflects a misunderstanding of marginal rates. If you earn an extra £1,000 above the threshold, you repay an additional £90 (9% of £1,000). You keep £910 — minus income tax and National Insurance, of course, but you're still significantly better off.

There is no scenario in which earning more money makes you worse off because of student loan repayments. The 9% marginal rate on income above the threshold is a cost, yes, but it never exceeds 9%. You always keep at least 91% of every additional pound you earn (before other taxes). Earning more always means having more money in your pocket, even with student loan deductions.

Myth 9: "Student Loans Are Passed to Family If I Die"

Absolutely not. If a borrower dies, the student loan is cancelled immediately. It does not pass to a spouse, parents, children, or the estate. This is written into law and applies to every type of UK student loan. No family member will ever be asked to repay a deceased person's student loan.

This makes student loans fundamentally different from mortgages (which do pass to the estate) and other debts (which must be repaid from estate assets). There is no need to take out life insurance to cover a student loan. For full details, see our article on what happens to student loans after death.

Myth 10: "I Need to Apply for Write-Off"

When your loan reaches its write-off date — 25, 30, or 40 years after you became eligible to repay, depending on your plan — the remaining balance is cancelled automatically. You do not need to fill in a form, contact the SLC, or take any action whatsoever. The SLC knows when your write-off date is and will process it without any input from you.

Once written off, no further deductions will be made from your salary. HMRC is notified, and your employer is instructed to stop the deduction. If you're self-employed, you simply stop including student loan repayments in your Self Assessment tax return from the relevant tax year onwards.

The only situation where you might need to contact the SLC is if deductions continue after your write-off date due to an administrative delay — this is rare but can happen. A quick phone call to the SLC will resolve it. But you never need to proactively apply for write-off.

The Bottom Line

Most anxiety around student loans stems from treating them like commercial debt. They're not. They're an income-contingent graduate contribution with built-in protections: you only pay when you earn enough, you never pay more than 9% of your income above the threshold, and the balance is automatically cancelled after a set period. Understanding these facts — and letting go of the myths — is the first step to making smart financial decisions as a graduate.
