How it works
- Select your plan and enter your SLC balance and gross salary.
- We calculate 9% of income above your plan threshold (or 6% for postgraduate loans).
- Interest is applied illustratively to show whether you are likely to repay in full or have the balance written off.
Common questions
- Which plan am I on?
- Check your payslip, HMRC Personal Tax Account or Student Loans Company account. Plan 2 covers most 2012–2023 English starters; Plan 5 covers 2023+ starters.
- Does this affect my credit score?
- No. Student loans do not appear on credit files, though mortgage lenders may ask about monthly repayments.
- Should I overpay based on this?
- Usually only if you are a high earner likely to clear the loan before write-off. For most graduates, voluntary overpayments give no benefit.
