Will I Ever Pay Off My Student Loan?
It's one of the most common questions graduates ask after university.
If you check your student loan balance and see that it's still growing because of interest, it's natural to wonder whether you'll ever repay it completely.
The short answer is: it depends on your repayment plan, your earnings and how long you remain above the repayment threshold. For many borrowers, the loan is eventually written off before the full balance is repaid.

Student loans don't work like normal debt
One of the biggest misconceptions is that a student loan should be treated like a personal loan or credit card.
In reality, repayments are based on your income, not on how much you borrowed.
For undergraduate loans, you usually repay 9% of income above your plan's threshold. For postgraduate loans, you repay 6% above the threshold. If your income falls below the threshold, repayments stop automatically.
That means your monthly repayment is determined by your salary rather than your outstanding balance.
Student loan plans at a glance
The repayment rules depend on which plan you're on.
Plan | Who it usually applies to | Repayment rate | Write-off period |
|---|---|---|---|
Plan 1 | Most borrowers who started undergraduate study before 1 September 2012 in England or Wales, and many borrowers from Northern Ireland | 9% of income above the threshold | 25 years after the April you were first due to repay, or when you turn 65 if earlier |
Plan 2 | Most borrowers who started undergraduate study in England or Wales from 1 September 2012 to 31 July 2023 | 9% of income above the threshold | 30 years after the April you were first due to repay |
Plan 4 | Most borrowers who received student finance from Scotland | 9% of income above the threshold | 30 years after the April you were first due to repay, or when you turn 65 if earlier |
Plan 5 | Most borrowers who started undergraduate study in England from 1 August 2023 onwards | 9% of income above the threshold | 40 years after the April you were first due to repay |
Postgraduate Loan | Postgraduate master's or doctoral loans | 6% of income above the threshold | 30 years after the April you were first due to repay |
Thresholds change each tax year, so always check the current figures on GOV.UK.
What determines whether you'll repay your loan?
Several factors affect whether you'll clear your balance before it's written off.
These include:
Which student loan plan you're on.
Your salary throughout your career.
How quickly your earnings grow.
Periods where you stop working or work part-time.
Interest added to your loan.
Whether you have more than one student loan.
Someone who becomes a high earner soon after graduating is much more likely to repay their loan in full than someone whose earnings remain close to the repayment threshold.
Why many graduates never repay the full balance
For many borrowers, repayments simply aren't large enough to clear both the original loan and the interest added over time.
Because repayments depend on income rather than the size of the loan, people with average earnings may continue making repayments for many years while their remaining balance reduces slowly—or, in some cases, even increases.
This is especially common on plans with long repayment periods, such as Plan 2 and Plan 5. Plan 5 has the longest standard write-off period at 40 years, but even that does not guarantee the loan will be repaid in full.
Once the write-off period is reached, any outstanding balance is normally cancelled.
When is a student loan written off?
Each repayment plan has its own write-off rules.
The number of years before a loan is cancelled depends on when you took out the loan and which repayment plan you're on. The key date is usually the April after you first became due to repay, not the date you graduated.
Here are the standard write-off periods again:
Plan 1: 25 years after the April you were first due to repay, or when you turn 65 if earlier.
Plan 2: 30 years after the April you were first due to repay.
Plan 4: 30 years after the April you were first due to repay, or when you turn 65 if earlier.
Plan 5: 40 years after the April you were first due to repay.
Postgraduate Loan: 30 years after the April you were first due to repay.
In some circumstances, such as death or permanent disability, the loan can also be cancelled earlier.

Does a bigger student loan mean higher repayments?
No.
This often surprises graduates.
Whether you borrowed £20,000 or £70,000, your monthly repayment is generally based on your income rather than the size of your loan.
If two graduates earn the same salary and are on the same repayment plan, they'll usually make the same monthly repayment, even if one borrowed significantly more.
The main difference is how long repayments continue before the balance is cleared or written off.
If you have both an undergraduate loan and a postgraduate loan, separate deductions can apply at the same time. For example, you could pay 9% on your undergraduate loan and 6% on your postgraduate loan, each calculated according to its own rules.
Should you make extra repayments?
For most borrowers, making voluntary repayments isn't always the best financial decision.
If you're unlikely to repay the loan before it's written off, paying extra may simply reduce the amount that would eventually have been cancelled.
However, some higher earners who expect to repay their loan in full could save money on interest by making additional repayments.
Because everyone's circumstances are different, it's worth understanding your likely lifetime repayments before making overpayments.
Does interest mean you'll never repay it?
Interest increases the balance of your loan over time.
For some graduates, particularly those with lower or average earnings, interest may be added faster than repayments reduce the balance.
This doesn't necessarily mean you've done anything wrong.
Remember, your required monthly repayment is still based on your income, not your balance.
The balance itself often matters less than many borrowers think, because the repayment rules and write-off date are fixed by your plan.
Should you worry about your student loan balance?
For most graduates, the answer is no.
Unlike commercial debt, student loans don't affect your monthly repayments because the balance has increased.
The most important figure is your salary.
As your earnings change, your repayments change too.
For many people, it's more useful to think of student loan repayments as an additional payroll deduction rather than a conventional debt that needs to be cleared as quickly as possible.
Estimate your student loan repayments
If you want to understand how your student loan affects your take-home pay, our salary calculator can estimate your repayments based on your income and repayment plan.
By comparing different salaries and plans, you can see how much you would repay under Plan 1, Plan 2, Plan 4, Plan 5 or a Postgraduate Loan, and whether you're likely to clear the balance before the write-off date.
