    Postgraduate loans charge RPI + 3% interest from day one, regardless of your income. This is a higher rate than most undergraduate plans and begins accruing while you are still studying.

    Who Has a Postgraduate Loan?

    You have a Postgraduate Loan if you took out a:

    • Postgraduate Master's Loan — available to students studying a taught or research Master's degree in England
    • Postgraduate Doctoral Loan — available to students studying a doctoral degree (PhD) in England

    Students in Scotland, Wales, and Northern Ireland have separate postgraduate funding arrangements and should check with their respective funding bodies.

    How Postgraduate Loan Repayments Are Calculated

    You repay 6% of your income above the repayment threshold — a lower rate than undergraduate loans. The threshold for 2025/26 is £21,000 per year (£1,750 per month).

    Example: If you earn £30,000 per year, you repay 6% of (£30,000 minus £21,000) = 6% of £9,000 = £540 per year, or about £45 per month.

    Repaying Both an Undergraduate and Postgraduate Loan

    If you have both an undergraduate loan and a Postgraduate Loan, you repay both simultaneously. Your undergraduate repayment is calculated at 9% above its threshold, and your Postgraduate repayment at 6% above £21,000. These are added together and appear on your payslip.

    Example at £35,000 salary (Plan 2 + Postgraduate):

    • • Plan 2 repayment: 9% of (£35,000 minus £28,470) = £587.70/year = £48.98/month
    • • Postgraduate repayment: 6% of (£35,000 minus £21,000) = £840/year = £70.00/month
    • Total: £1,427.70/year — approximately £118.98/month

    When Does the Postgraduate Loan Get Written Off?

    Postgraduate Loans are written off 30 years after the April following your graduation.

    Interest on Postgraduate Loans

    Interest on Postgraduate Loans is charged at RPI + 3% from the day the first payment is made, regardless of your income level. This is the same rate as Plan 2 loans for high earners and begins immediately — including while you are still studying.

    Frequently Asked Questions

    Q: Does my Postgraduate Loan affect my credit score?

    A: No. Postgraduate Loans are not recorded on your credit file.

    Q: Can I defer my Postgraduate Loan repayments?

    A: Yes — repayments only begin once your income rises above £21,000. If you are below this threshold at any point, repayments pause automatically.

    Q: I have a Master's and a PhD loan — do I repay both?

    A: Both are classified as Postgraduate Loans and are combined into a single repayment calculation at 6% above £21,000. They are not treated separately.
