Overpay or Invest

Which student loan plan am I on?

. Figures are for 2026–27 and are compared with GOV.UK every month. How we check.

Which “plan” you’re on depends on where you studied and when your course started — not on anything you chose. It decides your repayment threshold, your interest rate and how many years until any remaining balance is written off, so it’s worth being sure before you rely on any numbers, including the ones from the calculator.

The plans, roughly

Your plan depends on where you applied for student finance and when your course started. You can’t choose it, and if you’ve borrowed more than once you could be on different plans for different loans.

These are the plans this site’s calculator covers, with their thresholds and rates as used from the 2026–27 tax year. See the disclaimer for where those figures come from.

Why this matters

Plan 2 and Plan 5 in particular are easy to mix up if you started university around 2023, and the difference is significant: Plan 5’s threshold is lower (so repayments start on a smaller salary) but the loan runs for longer before anything unpaid is written off. Getting the plan wrong in the calculator can flip the entire overpay-or-invest verdict.

How to check for certain

Guessing from memory isn’t reliable enough for a decision involving real money. The definitive way to check:

  1. Sign in to your student loan repayment account. Your plan type is shown there, and you can download your “active plan type letter”.
  2. Ask your employer which plan they have you on. If it differs from your letter, show them the letter so they can update payroll. See is my employer using the right student loan plan?
  3. Check your annual statement from the Student Loans Company, which is normally available in your online account by the end of August.

If you have both an undergraduate plan and a Postgraduate Loan, both apply at the same time — you’re not on “one or the other.”

Once you know your plan, head to the calculator and pick it from the dropdown; the threshold, share of income and interest rate are filled in automatically.
