Student Loans Overview

Increased tuition fees, rising interest rates and the replacement of maintenance grants with loans, means most graduates now leave university with significant student debt (average £50,800), which they will be repaying over many years. But whilst this might sound daunting, far more relevant than the amount of debt you rack up, is the amount you actually repay.
A student loan is not like a normal debt – delayed repayments, the write-off period and the fact that repayments are linked to what you earn not what you owe, make the student loan one of the safest, and for some the cheapest forms of borrowing. So it’s not always wise to pay off your loan early, even if you can afford to.

Tuition fees

Universities are allowed to raise tuition fees each year in line with inflation. Maximum annual fees (charged by the majority of universities) are currently capped at £9,250.

Interest rates

The interest charged on student loans is linked to inflation. For the academic year 2022-23, the interest rate will be 4.5% (while you’re studying) and then between 1.5 – 4.5% (depending on your earnings).

Maintenance support

You can get additional student finance to help towards your living costs at university/college; however maintenance grants were replaced with maintenance loans in 2016. As a result, students from lower-income families, who now have to borrow more to fund themselves through university, are graduating with the highest debts, of over £57,000.

Find out when you start and stop repaying your loan, and how much you pay.
Piggy - repay student loan
Unlike commercial loans, repayments are not based on how much you owe on your outstanding debt, but on how much you earn.  Interest rates are also staggered according to income.  Whilst this does mean high earners could end up paying back far more than they borrowed (because of interest charges), it also means if you don’t earn enough, you don’t need to repay.

When to repay

You don’t have to start paying back your student loan until you earn £27,295 a year.
The earliest you begin repayments is the April after leaving university/college.
Even after you start repaying, if your income drops below the threshold in any year, you can stop repayments (unlike normal borrowing, where you must continue regardless of your circumstances).

How much?

Whatever you borrowed, repayments are proportionate to your earnings – you repay 9% of everything you earn above the £27,295 threshold.

If you earn £25,000 per year, you repay nothing.

If you earn £31,295, that’s £4,000 above the threshold, so your repayment will be 9% of £4,000 = £360 per year, or £30 a month.

If your income falls, so do your repayments.
This staggered repayment system means that some graduates could be paying back their loan into their 40s and 50’s.

Monthly loan repayments related to income

Annual income (before tax) Monthly repayment
£27,295 £0
£30,000 £20
£35,000 £58
£40,000 £95
£45,000 £133

Write-off period

Any unpaid student debts are wiped after 30 years.
However much is still owing, your repayments stop, and it’s estimated that around 83% of graduates will not pay back the full amount they borrowed. The system is designed so that only the very highest earners repay their total debt.
You can check your repayments and balance in your online account or your annual statements from SLC.

Interest  on Student Loans


Interest is what you are charged for borrowing money, but in the case of student loans, it’s important to remember that what you are charged is not necessarily what you pay! Your repayments are calculated on how much you earn, not how much you owe (your outstanding loan + interest charges).


How it works

For student loans, the interest rate is set each September, based on the Retail Prices Index (RPI) inflation rate from March of the same year. Your outstanding loan amount accrues interest during university and after graduation.

For academic year September 2021 – August 2022:

While you’re studying, and until the April after you have left university:  interest is charged at RPI + 3% (= 4.5%).
From the April after graduation, charges are staggered according to income.
From April 2022, graduates earning under the £27,295 repayment threshold will be charged a basic rate equivalent to RPI inflation (= 1.5%). Then interest is charged on a sliding scale, dependent upon income, up to a maximum rate of RPI + 3% (= 4.5%). This basically means that the higher your income, the more interest will be added to your student loan, until you have paid it off.

Find out the current interest rate on your student loan

The Institute for Fiscal Studies (IFS) calculates that the average student will have accrued £5,800 interest by the time they graduate. And higher earners charged the top rate after graduation ‘could end up paying interest of £40,000 on top of the amount borrowed.’

Avoid penalty interest rates

Keep the Student Loans Company up to date with your contact details and employment information, to avoid being charged a penalty rate. If you don’t provide the information they require, they may apply the top interest rate regardless of your income, until they have all the details they need.

Interest rates are linked to inflation

There is mounting pressure for the Government to switch from using the RPI (Retail Prices Index) to the lower CPI (Consumer Prices Index), for calculating student loan interest rates. Why does it matter?
Both RPI and CPI measure inflation (the rate of change of prices for goods and services), by monitoring the changing cost of a ‘basket’ of goods e.g. food, petrol and household products, but they cover different items and are calculated differently. RPI almost always gives a higher figure (on average 1.2% above CPI). The higher the inflation rate, the higher the interest rate charged on student loans, so it does make a difference which measure is used.



Inflation – February 2022

5.5% CPI    Consumer Prices Index

7.8% RPI    Retail Prices Index

The Government generally pegs the payments it makes to the lower CPI (e.g. pensions, benefits) and the payments it receives to the higher RPI (e.g. student loan repayments, train fares and taxes). However, to help struggling small businesses, they have now switched business rates to rise in line with CPI, so we hope student loans will follow suit!

Find out more here about the difference between RPI and CPI.


If interest rate = inflation rate, there is no real cost

Inflation is the general rate at which prices rise. For those graduates being charged interest equivalent to the rate of inflation (RPI), there is no real cost of your loan:

If inflation = 3%, it means that if your loan can buy a certain basket of goods this year, the price of that same basket will rise by 3% next year; so you would need to spend 3% more to buy exactly the same things. Therefore, paying back 3% more is the same real cost as your original loan.


How does a change in interest rates affect student loans?

A rise in interest rates increases debt levels for everyone, but only the repayments of high earners
Higher interest rates will increase the overall amount you owe on your student loan (amount borrowed + interest), but it won’t impact your monthly repayments, and most people will end up paying no extra overall.

Monthly repayments

A rise in rates won’t change what you repay each month, because that is based on how much you earn, not how much you owe (i.e. each year you repay 9% of your earnings above £27,295).

Overall debt

Most people will be unaffected by a rise in interest rates, because they will not clear the original sum borrowed plus all the added interest, before their debt is wiped. Whilst they might pay some interest, it won’t all be at the higher rate. And lower earners won’t even repay the amount they borrowed, never mind any interest it has accrued.
The borrowers who will feel most impact are bigger earners who are charged around the maximum interest rate and are set to pay off their loan within the 30-year period. The increased debt will take them longer to clear, with the higher interest adding thousands to the amount they pay back.
The very highest earners pay off their loans more quickly (because 9% of their income above the £25,725 threshold is a larger amount of money); faster repayments means their debt accrues less interest, so they will be less affected by a rise in rates.

How You Repay

How you repay student loans -Purple camouflage pig
Once you start earning over the £27,295 threshold, your student loan is repaid automatically via the UK tax system. It works differently depending on whether you are employed, self-employed or living abroad.

If you work for an employer

Repayments will be deducted automatically from your salary via PAYE (Pay As You Earn), along with Income Tax and National Insurance. You need to tell your employer that you have a Student Loan (usually by completing an HMRC New Starter Checklist for your first job).

If you complete a Self Assessment tax return

If you are self-employed, or have other income that is not taxed automatically through the PAYE system, you pay tax and student loan repayments through the Self Assessment scheme. Notify HMRC that you have a Student Loan by ticking the box on your Self Assessment tax return. They will then calculate your repayments, which you make at the same time as you pay your tax.

If you live outside the UK

After you’re due to start repaying your loan, if you are travelling or living abroad for more than 3 months, you will need to tell the Student Loans Company (SLC). They will work out what you have to repay while you’re abroad. Be sure to keep your account details up to date, or you may be charged penalty interest rates and charges.

Budget for repayments

It’s a good idea to set and keep to a monthly budget to reflect your income and outgoings, including your student loan repayments (even if they are deducted automatically before you receive your salary).

Keep track so you don’t overpay!

Many graduates have student loan repayments deducted from their salary automatically via PAYE, and for most the system works well. But thousands of graduates accidentally overpay their debts (in the worst cases up to £10,000) e.g. where repayments are collected too early, when their income is below the threshold, or after the loan has already been cleared. Problems occur mainly because HMRC only reports payments once annually to the Student Loans Company at the end of the tax year, by which time a large sum of overpayments could have been made. The Government plans to fix the system, but do be proactive and regularly check your payments, particularly if your circumstances change, or you’re close to clearing your debt.

Student Loan Overpayments & Refunds – Money Saving Expert


Impact on Credit Rating & Future Borrowing

Your student loan is not included on your credit file, so it will not affect your credit rating and should not impact future borrowing.

However it might affect mortgage deals, because lenders carry out affordability checks to assess what level of mortgage repayments you could manage on your take-home pay; therefore they will take into account all your monthly outgoings, including student loan repayments.

Postgraduate Students

Postgraduate loans are now available throughout the UK, although the amounts and rules for eligibility vary, depending on where you are studying: England, Scotland, Wales, or Northern Ireland.
In England, postgraduate students can apply for a loan of up to £11,836 for a Masters degree (2022-23), to help with course fees and living costs. Interest will be charged at RPI + 3% (= 4.5%).
Just like your undergraduate loan, repayments are income-contingent – you only repay if/when you’re earning enough once your course ends. The repayment threshold is £21,000, and you repay 6% of your annual earnings over this threshold. Any remaining debt is wiped after 30 years. If you already have an undergraduate student loan, you will repay both at the same time.
