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 1 | 25 years (or age 65) |
| Plan 2 | 30 years |
| Plan 4 | 30 years (or age 65) |
| Plan 5 | 40 years |
| Postgraduate | 30 years |
Calculating Repayments
| 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 |
