How Student Loans Eat Your New Job Pay Rise | UK Money Daily
You’ve just got a new job. Your employer says you’re getting a pay rise. Exciting, right? But then you check your payslip and wonder – where did all that extra money go?
For millions of UK graduates, the answer is your student loan repayment. It quietly takes a chunk of every pound you earn above a certain level. And the bigger your pay rise, the more it will cost.
This guide explains exactly how student loan repayments work in the UK, how a pay rise changes the amount you take home, and what smart steps you can take to keep more of your hard-earned money.
What Is Student Loan Repayment in the UK?
A student loan repayment in the UK is nothing like paying off a credit card or bank loan. You don’t get a monthly bill. You don’t choose when to pay. The money comes out of your wages automatically – just like income tax – through a system called PAYE (Pay As You Earn).
The basic idea is simple: You only start making payments when you earn enough. If your salary is below a set limit called the repayment threshold, you won’t have to pay anything back – no matter how much debt you have. The moment your income crosses that line, a portion of your earnings above that goes directly to the student loan company.
Think of it less like debt and more like a graduated tax. It’s income-based, automatic, and gets forgiven after a certain number of years – whether you pay it off or not.
Which Repayment Plan Are You On?
Your repayment plan depends on when and where you started your college course. You don’t have a choice. Here is a brief breakdown of the current schemes and their 2026/27 thresholds:
| Plan | Who It Applies To | Repayment Threshold | Rate | Written Off After |
|---|---|---|---|---|
| Plan 1 | England/Wales before 2012, Northern Ireland | ÂŁ26,900 | 9% | 25 years |
| Plan 2 | England/Wales from 2012 | ÂŁ29,385 | 9% | 30 years |
| Plan 4 | Scotland | ÂŁ33,795 | 9% | 30 years |
| Plan 5 | England from 2023 onwards | ÂŁ25,000 | 9% | 40 years |
| Postgraduate | Master's or PhD loan | ÂŁ21,000 | 6% | 30 years |
The most common scheme for recent graduates is Plan 2. If you started university in England or Wales between 2012 and 2023, that’s your plan. If you started in 2023, you’re on Plan 5, which has a lower threshold – meaning payments start earlier.
How Does a Pay Rise Affect Your Repayments?
You only pay 9% on income above your threshold – not your full salary. So when you get a pay rise, the 9% charge only applies to the extra amount above the threshold.
Example (Plan 2):
Earning £32,000: You’re £2,615 above the threshold. You pay about £235 per year (~£20/month).
Earning £40,000: You’re £10,615 above the threshold. You pay about £955 per year (~£80/month).
The increase only applies to extra income, but it still reduces your take-home pay.
The Frozen Threshold Problem
The repayment threshold has stayed low in recent years. This means graduates now pay more than before.
For Plan 5, the threshold is ÂŁ25,000 and stays fixed until at least 2027. This makes people start paying earlier and for longer.
Lower earners feel this the most because even small income increases trigger repayments.
What Happens with Bonus or Overtime?
Your repayment changes based on your monthly income. If you get a bonus, your deduction increases for that month.
Next month, it returns to normal. Over the year, things balance out.
The Hidden Sting: Tax + NI + Loan
When you add all deductions together, your take-home pay becomes much lower.
Example:
Income Tax: 20%
National Insurance: 8%
Student Loan: 9%
Total deduction = 37%
For higher earners, it can go above 50%.
Smart Move: Salary Sacrifice
You can reduce repayments using a salary sacrifice pension.
This lowers your official salary and reduces loan payments.
Example: £35,000 salary with £2,400 sacrifice → repayment calculated on £32,600.
This saves money on loans, tax, and NI.
Should You Pay Early?
For most people, the answer is no.
Many borrowers never repay the full loan before it gets written off.
Only consider early payment if you are close to finishing the loan.
Conclusion
A pay rise is good, but student loans reduce how much you actually get.
Key points:
• You pay only above the threshold
• Pay rise increases repayment slightly
• Threshold freeze increases payments
• Total deductions can exceed 50%
• Salary sacrifice can help reduce payments
