How to Figure Out Your Student Loan Repayments
Student loan repayment depends upon your earnings and the repayment threshold that corresponds with your loan plan. This is the easy step-by-step student loan repayment formula used:
- Repayment threshold is subtracted from your gross annual salary.
- Calculate the repayment percentage:
- Plan 1, 2, 4, or 5: You repay 9% of anything you earn above the threshold.
- Postgraduate loan: You repay 6% of anything earned above the threshold.
- Divide the annual repayment by twelve.
For Example
In 2025/26, a person earning £30,000 with a Plan 2 loan will:
- Calculate the income exceeding the threshold: £30,000 (salary) – £28,470 (threshold) = £1,530.
- Calculate 9% of pounds exceeding the threshold: 9% of £1,530 = £137.70 per annum.
- Calculate monthly payments: £137.70 ÷ 12 = £11.48 per month.
Frequently Asked Questions on Student Loan Repayments
Do overtime or bonuses affect repayments?
Yes. Repayments are calculated on total earnings, including bonuses, overtime, and commissions. Your employer will automatically make the calculations via PAYE.
What happens if my salary changes?
If your salary changes, your repayments will be adjusted automatically. Should your income drop below the threshold, you will pay less; should it rise above, you will pay more.
Can I pay off my student loan early?
Yes, you are able to repay your student loan early with no penalty. But think twice about repaying it early, as most student loan debts carry a lower interest rate than other debt.

How Interest Rates Are Applied to Student Loans
The interest that accrues varies depending on the loan type and rating band of income:
- Plan 1: Interest accrued is at lower rate between RPI or Bank of England base rate + 1% (subject to government policy).
- Plan 2: Interest accured depends on your income between RPI and RPI + 3%.
- Plan 4: Interest accured depends upon RPI or RPI + 1% (check SLC for latest).
- Plan 5: Interest accured depends upon RPI.
- Postgraduate: Interest accured is RPI + 3%.
You should keep track of your SLC statements at least annually to monitor interest accrual.
The Effect of Your Student Loan Repayments on Your Mortgage Application
Student loans do indeed have an effect on mortgage affordability checks in that repayment reduces disposible income. However, affordability is considered more by lenders than how much you have left to pay back. Here's how to best handle it:
- Keep up good financial behaviour by settling your debts on time with a good credit history.
- Start looking at affordability with the mortgage calculator factoring in repayments.

Freedom from finance needs continuous learning and proactive handling of your finances.
