Student Loan Repayment Explained UK — How It Actually Works

Understanding student loan repayment in the UK. What you pay, when payments start, Plan types, and whether to pay off early or not.

Student loan repayment confuses many graduates. Here’s how it actually works.

The Basic Concept

How Repayment Works

Principle Reality
Works like a tax 9% of income over threshold
Not like a mortgage Not fixed monthly payments
Automatic Through PAYE
Income-linked Earn less, pay less
Written off eventually 25-40 years depending on plan

Key Features

Feature What It Means
Threshold-based Only pay on income above threshold
9% rate Standard rate for undergraduate loans
No credit impact Doesn’t appear on credit report
Not real “debt” More like graduate tax

Loan Plan Types

Which Plan Are You?

Plan Who
Plan 1 English/Welsh students before Sept 2012, Scottish students
Plan 2 English/Welsh students from Sept 2012
Plan 4 Scottish students from Sept 2012
Plan 5 English students from Sept 2023
Postgraduate Master’s and PhD loans

Thresholds (2024-25)

Plan Annual Threshold Monthly
Plan 1 £24,990 £2,082
Plan 2 £27,295 £2,274
Plan 4 £31,395 £2,616
Plan 5 £25,000 £2,083
Postgraduate £21,000 £1,750

Write-Off Periods

Plan Written Off After

Plan 2 30 years
Plan 4 30 years (or age 65)
Plan 5 40 years
Postgraduate 30 years

Calculating Repayments

The Formula

Step Calculation
1 Take annual salary
2 Subtract threshold
3 Multiply by 9%
4 Divide by 12 for monthly

Plan 2 Examples

Salary Above Threshold Annual Repayment Monthly
£25,000 £0 £0 £0
£30,000 £2,705 £243 £20
£35,000 £7,705 £693 £58
£40,000 £12,705 £1,143 £95
£50,000 £22,705 £2,043 £170
£60,000 £32,705 £2,943 £245

If You Have Multiple Loans

Situation Repayment
Plan 2 + Postgraduate Pay 9% Plan 2 + 6% Postgraduate = 15%
Plan 1 + Plan 4 Unlikely but would be separate thresholds
Plan 5 in future Check Student Loans Company

Interest Rates

Plan 2 Interest

Income Interest Rate
Below threshold RPI
Up to £49,130 RPI + up to 3% (sliding scale)
Above £49,130 RPI + 3%
While studying RPI + 3%

What This Means

Reality Explanation
Interest is high But doesn’t matter for most
Most won’t repay in full Loan written off anyway
For high earners Interest increases total paid
Don’t panic It’s not like credit card debt

Should You Pay Off Early?

Generally No

Reason Explanation
Written off eventually Unpaid balance disappears
Low earners never repay Or repay less than borrowed
Money could go elsewhere ISA, pension gets tax relief
No credit impact Not on credit report

Maybe Yes If

Situation Why
Very high earner Will repay in full anyway
Already maxed ISA/pension Extra cash available
Approaching write-off With balance left
Emigrating May have to repay differently

Example: £50k Debt, Plan 2

Scenario Outcome
Earn £35k throughout career Never fully repay, written off
Earn £60k+ May repay, plus interest
Pay off now Save interest but opportunity cost
