Student and Postgraduate Loan Thresholds and Rates
Employees repaying student or postgraduate loans, employers operating payroll, and self-employed individuals completing Self Assessment who need to understand how repayments are calculated and collected.
Explaining why student and postgraduate loan deductions appear, how repayment thresholds and rates work, and why amounts can differ between individuals.
Student and postgraduate loan repayments affect take-home pay and payroll calculations. Errors, incorrect plan selection, or misunderstanding thresholds can result in over- or under-deductions, which may require correction later.
New Student Loan Repayment Rates and Thresholds Explained
From 6 April 2025, new thresholds for student loan repayments will take effect, impacting borrowers across the UK. Whether you’re on Plan 1, Plan 2, Plan 4, or repaying a postgraduate loan, here’s a breakdown of the latest changes and what they mean for you.
Effective from 6 April 2025, the thresholds and repayment rates for various student loan plans will be as follows:
- Plan 1: £26,065
- Plan 2: £28,470
- Plan 4: £32,745
The loan repayment terms for students who commenced their courses before 1 September 2012 are categorised under ‘Plan 1’. Those who began their studies after 1 September 2012 are subject to ‘Plan 2’ terms. Under these plans, repayments are set at a rate of 9% of income above the respective threshold.
Student loans taken out by borrowers in Scotland are classified as ‘Plan 4’ loans, with a repayment threshold of £32,745, and the repayment terms are similar to those of Plan 2 loans.
For postgraduate loans, the threshold remains unchanged at £21,000, with repayments deducted at a rate of 6% of income above this amount.
How Student and Postgraduate Loan Repayments Work
Student loan and postgraduate loan repayments are collected through the UK tax system.
Repayments are:
- Income-based
- Only due once earnings exceed the relevant repayment threshold
- Collected automatically through PAYE or Self Assessment
Deductions are shown separately on payslips and are not the same as income tax or National Insurance.
Student Loan Plans and Repayment Rates
Student loan repayments depend on which plan applies. Each plan has its own:
- Repayment threshold
- Repayment rate
Once income exceeds the threshold for the relevant plan, repayments are calculated as a percentage of earnings above that level.
Postgraduate Loan Repayments
Postgraduate loans are repaid separately from undergraduate student loans.
Key points include:
- Repayments apply once income exceeds the postgraduate loan threshold
- Postgraduate loan repayments are made in addition to student loan repayments
This means some individuals may see multiple loan deductions on their payslip at the same time.
Real-World Application
In practice:
- Employees see student and postgraduate loan deductions on their payslips once thresholds are exceeded
- Employers calculate and deduct repayments through payroll based on the plan information provided
- Self-employed individuals repay loans through Self Assessment when completing their tax return
Deductions may change where income fluctuates or where more than one loan applies.
Risks and Common Issues
Issues can arise where:
- The wrong loan plan is applied
- Repayments are over- or under-deducted through PAYE
- Loan repayments are not correctly reflected in Self Assessment
These situations are usually administrative, but they can affect cash flow and may require later adjustment.
