When Do You Start Paying Back Student Loan?

Finishing university is exciting, until the first thought of student loan repayments hits. Many graduates wonder, “When do you start paying back student loan?” The answer isn’t always simple. It depends on your income, the type of loan plan you’re on, and where you live. 

Knowing the right time to start repaying can help you stay in control of your finances and avoid any surprises when your first paycheck arrives.

In this article, we’ll break down everything every graduate should know before repayments begin. You’ll learn exactly when repayments start in the UK, what the student loan repayment threshold means, and how student loan repayment works depending on your plan. 

We’ll also cover what happens if your income drops, if you move abroad, and share practical tips to manage your repayments with confidence.

When Do You Start Paying Back Student Loan?

Many graduates ask the same question as soon as they complete their studies, “When do you start paying back student loan?” The answer depends on when you finish or leave your course and how much you earn. 

In the UK, your repayments don’t begin straight away. Instead, there’s a built-in delay to help you settle into work and earn above a certain amount before any money is taken from your income.

For most full-time students in the UK, repayments begin in April after you leave your course, regardless of whether you graduate or not. For example, if you finish your degree in June 2025, your repayments will start from April 2026, provided your income is above the repayment threshold for your loan plan. This rule gives new graduates a few months to find work and adjust before they begin repaying.

If you studied part-time, the rule changes slightly. You’ll start repaying the April four years after your course begins, or the April after you leave, whichever comes first. This means even if you’re still studying part-time after four years, you may start repaying if you earn above the threshold.

There are also a few special cases to keep in mind:

• If you leave your course early, the same “April after you leave” rule applies.
• If you continue to postgraduate study, you may have separate repayment rules for your postgraduate loan.
• If you live or work abroad, repayments will depend on your overseas income and local currency equivalent.

Your student loan repayment doesn’t begin automatically when you graduate, it begins when your income meets the required level.

Student Loan Repayment Threshold UK

The student loan repayment threshold UK is the minimum annual income you must earn before you start repaying your loan. You only repay a percentage of your income that’s above this threshold, not your entire salary. If your income falls below the threshold, your repayments stop until you earn enough again, giving you flexibility and peace of mind.

Each repayment plan in the UK has a different threshold. Here are the current thresholds for the 2024/25 tax year:

• Plan 1: £24,990 a year (mainly for students who started courses before September 2012)
• Plan 2: £27,295 a year (for students who started between September 2012 and July 2023)
• Plan 4 (Scotland): £31,395 a year
• Plan 5: £25,000 a year (for new borrowers from August 2023 onwards)
• Postgraduate Loan: £21,000 a year

If you earn more than your plan’s threshold, you’ll pay a percentage of the amount you earn above it typically 9% for undergraduate loans and 6% for postgraduate loans. For example, if you’re on Plan 2 and earn £30,000 a year, you’ll repay 9% of the £2,705 you earn over the £27,295 threshold.

It’s also important to note that thresholds are reviewed and updated each tax year. The government may raise or freeze them depending on inflation and policy changes. Always check the latest figures on the Student Loans Company (SLC) or GOV.UK websites to stay updated.

And what happens if your income drops below the threshold? Your repayments stop automatically. This applies whether you’re between jobs, working part-time, or on parental leave, giving you breathing space when you need it most.

Knowing these thresholds is key to planning your finances and avoiding surprises when you start earning. But thresholds are only part of the equation next, let’s look at how student loan repayment works in the UK and what it really means for your take-home pay.

How Student Loan Repayment Works UK

Once you know when repayments start and what your threshold is, the next step is to understand how repayments are actually calculated. In the UK, student loan repayments are based entirely on your income, not on the total amount you borrowed. You only repay a set percentage of what you earn above your repayment threshold, making the system fair and flexible.

How Repayments Are Calculated

For most undergraduate loans, you’ll repay 9% of your income above the threshold, while postgraduate loans require 6%.

Example:
If you’re on Plan 2 and earn £32,000 a year:

• Your threshold is £27,295.
• You repay 9% of the £4,705 you earn above that limit.
• That works out to about £35 per month.

This percentage-based system means that if your income falls, your repayments automatically reduce too.

How Repayments Are Taken

Repayments are collected differently depending on how you earn your income:

• Employees (PAYE): If you work for an employer, your repayments are taken automatically through the Pay As You Earn (PAYE) system, along with tax and National Insurance. You’ll see the deductions clearly on your payslip.
• Self-employed individuals: If you’re self-employed, you’ll make repayments through your Self Assessment tax return. HMRC calculates the amount owed and adds it to your annual tax bill.

This automatic system ensures you don’t have to manually send payments each month, it’s all handled through payroll or tax reporting.

Interest Rates and How They’re Added

Interest starts building from the day the Student Loans Company (SLC) first pays your tuition or maintenance loan. The interest rate depends on your repayment plan and your income. For example, Plan 2 loans are linked to the Retail Price Index (RPI) and may include an additional percentage based on your income level.

Even though interest increases the balance you owe, it doesn’t affect how much you pay each month, your repayments are still based on your income above the threshold.

Loan Write-Off Periods

Your student loan doesn’t last forever. Each plan has a write-off period, meaning any remaining balance is cleared after a set number of years:

• Plan 1: Written off 25 years after repayments begin
• Plan 2: Written off after 30 years
• Plan 4 (Scotland): Written off after 30 years
• Plan 5: Written off after 40 years
• Postgraduate Loans: Written off after 30 years

So, while you may see interest added over time, many borrowers will never repay the full amount before the loan is eventually cleared.

But what happens if your income falls below the repayment threshold, or if you decide to work overseas? That’s where the UK’s repayment flexibility really comes into play

What Happens If You Earn Less or Move Abroad

The UK’s student loan system is designed to adjust to your income and lifestyle. Whether you earn less, take a career break, or move abroad, your repayments change accordingly.

If You Earn Below the Threshold

If your earnings fall below your repayment threshold, your repayments automatically stop. You don’t need to contact the Student Loans Company (SLC), it’s handled automatically through PAYE or Self Assessment.

This flexibility helps during times such as:

• Temporary unemployment
• Reduced working hours or part-time work
• Unpaid or parental leave

Once your income rises above the threshold again, your repayments restart automatically.

If You Move Abroad

If you move overseas, you’re still required to make student loan repayments if your income exceeds the overseas repayment threshold. These thresholds differ by country and take into account local living costs.

Before moving, you must:

1. Notify the Student Loans Company (SLC) of your new address and income.
2. Provide proof of your income, such as payslips or tax documents.
3. Allow the SLC to calculate your repayment amount in your local currency.

If you fail to provide your income details, the SLC may place you on a fixed repayment rate, which could be higher than what you actually owe, so it’s important to stay in touch and keep your details updated.

Temporary Breaks or Unemployment

If you take a career break, go on parental leave, or face unemployment, your repayments will pause automatically. You won’t need to make manual payments, and interest will continue to accrue at the usual rate for your plan.

Common Mistakes and Tips for Graduates

Many graduates start repaying their loans without fully understanding the details of their plan. This can lead to overpayments, missed updates, or confusion about how much they actually owe. Avoiding a few common mistakes can save you both stress and mone, and make your student loan repayment journey much smoother.

Common Mistakes to Avoid

Before diving into the common mistakes, it’s important to realise that managing your student loan is not just about making payments. Many graduates assume that once repayments start, everything happens automatically and correctly. 

In reality, small oversights can lead to unnecessary stress or even overpayments. Being proactive and aware of potential pitfalls can save you time, money, and worry as you navigate your loan repayment journey.

1. Not knowing which repayment plan applies to you

One of the biggest errors new graduates make is not identifying their student loan repayment plan. Each plan (Plan 1, 2, 4, 5, or postgraduate) has different rules, thresholds, and write-off periods. Repaying under the wrong assumption can cause unnecessary worry or budgeting mistakes.

Quick tip: You can find your plan type on any letter or email from the Student Loans Company (SLC) or by logging in to your online repayment account.

2. Forgetting to check your repayment status or income changes

Your repayments are based on your current income, so if your salary changes, either up or down, it’s important to check that your deductions match your actual situation. Some graduates don’t notice when repayments stop or start incorrectly, especially after switching jobs.

To stay on track:

• Review your payslips regularly to make sure student loan deductions are correct.
• If you’re self-employed, confirm your repayments are being added to your Self Assessment properly.
• Contact the SLC if something doesn’t look right.

3. Ignoring letters or updates from the Student Loans Company

The SLC sends important updates about interest rates, thresholds, and your repayment balance. Ignoring these could mean missing changes that affect how much you pay or when your loan will be cleared.

What To Do if You’re Unable to Pay off Your Debt?

If you’re unable to pay off debt, you might want to explore potential debt solutions in the UK. There are several options available in the UK, each with its own eligibility criteria. Choosing the right option can help resolve your debt issues, but the wrong one may make your financial situation worse.

However, it is essential to seek professional advice before committing to any debt solution. A debt advisor can help you assess your situation and guide you in selecting the most appropriate option.

Some of The Key Debt Solutions Available in England, Northern Ireland, and Wales:

• Debt Management Plan (DMP): An informal arrangement where you make monthly payments toward your debts. There is no legal commitment, but your creditors may agree to reduce interest or freeze fees.
• Individual Voluntary Arrangement (IVA): A formal agreement where you make regular payments to creditors over 5 or 6 years. The remaining debt may be written off, but this solution has strict criteria.
• Debt Relief Order (DRO): Designed for individuals in severe financial distress, this option freezes interest and allows a year of no payments, potentially leading to debt resolution.
• Bankruptcy:  A formal legal process that can clear most debts if you are unable to repay them. Bankruptcy provides a financial reset, but it also has serious long-term consequences, including restrictions on your financial affairs and potential asset loss.

Debt Solutions Available in Scotland

1. Protected Trust Deed: A formal agreement to repay part of what you owe over four years. The remaining debt may be written off afterward. It is legally binding and affects your credit rating.
2. Debt Arrangement Scheme (DAS): A government-backed scheme allowing you to repay your debts through a Debt Payment Programme (DPP) based on what you can afford. Interest and charges could be frozen, and creditors can’t take legal action.
3. Sequestration (Scottish Bankruptcy): A formal insolvency process where most debts may be written off, but assets may be sold to repay creditors. It offers a fresh start but comes with serious consequences.
4. Minimal Asset Process (MAP): A simplified form of bankruptcy designed for individuals with low income and few assets. It allows eligible debts to be written off after six months, provided the individual fully cooperates with the process. However, in practice, the process may take longer depending on the complexity of the case. MAP also offers lower fees and reduced administrative burden compared to full bankruptcy.

Caution: These debt solutions have both advantages and drawbacks, so it’s important to carefully weigh your options before making a decision.
