Which Student Loan Plan Am I On?
Your repayment plan depends on when and where you studied. Plan 1 is for those who started before September 2012 in England/Wales (or any year in Northern Ireland). Plan 2 is for England/Wales starters from September 2012 to July 2023. Plan 4 is for Scottish students. Plan 5 is for those starting from August 2023 onwards. Postgraduate loans are separate and repaid at 6% instead of 9%.
If you are unsure which plan you are on, check your payslip (it will show the plan type), contact the Student Loans Company, or log in to your SLC account online.
How Student Loan Repayments Are Calculated
You repay 9% of everything you earn above your plan's threshold. For Plan 2 in 2025/26, the threshold is £27,295. So if you earn £35,000, you repay 9% of £7,705 (the amount above the threshold), which works out to £693.45 per year or £57.79 per month.
Repayments are automatic through PAYE if you are employed. If you are self-employed, repayments are collected through your self-assessment tax return. You can have multiple plans at once (for example, Plan 2 plus a Postgraduate loan), and each is repaid simultaneously.
Repayment Thresholds by Plan (2025/26)
| Plan | Threshold | Rate | Write-off |
|---|---|---|---|
| Plan 1 | £24,990 | 9% | 25 years after first repayment (or age 65) |
| Plan 2 | £27,295 | 9% | 40 years after graduation |
| Plan 4 | £31,395 | 9% | 30 years after graduation |
| Plan 5 | £25,000 | 9% | 40 years after graduation |
| Postgraduate | £21,000 | 6% | 30 years after first repayment |
Should I Make Voluntary Repayments?
For most Plan 2 borrowers, voluntary repayments are not recommended. Because the loan is written off after 40 years, many graduates will never repay in full. Making extra repayments just means you pay more overall without reducing what you owe by enough to clear it before write-off.
Voluntary repayments make more sense if you are a high earner who will repay in full anyway, if you are close to clearing the balance, or if you are on Plan 1 (which has a shorter write-off period). Use this calculator to project your repayment timeline before deciding.
Frequently Asked Questions
What happens to my student loan if I move abroad?
You must inform the Student Loans Company if you move overseas. Your repayment threshold and amount will be adjusted based on the cost of living in your new country. If you do not report your move, you may face penalties. Repayments abroad are made directly to the SLC, not through your employer.
Do student loan repayments affect my credit score?
No. Student loan repayments do not appear on your credit file and have no impact on your credit score. However, the repayments reduce your take-home pay, which lenders may consider when assessing mortgage affordability.
Is interest charged on student loans?
Yes. Plan 2 loans are charged interest at the Retail Price Index (RPI) plus up to 3%, depending on your income. Plan 1 and Plan 4 loans are charged the lower of RPI or the Bank of England base rate plus 1%. Plan 5 loans are charged RPI only.
Can my student loan be written off early?
Student loans are written off after the plan's specified period (25 to 40 years depending on the plan). The write-off is automatic and the remaining balance is cancelled with no tax charge. There is no way to have it written off earlier unless you become permanently disabled.
