Why use UK Student Loan Calculator?

Student loan repayment in the UK works like a payroll tax band: nothing is repaid below the threshold, and 9% (6% for Postgraduate Loans) applies only to income above it. Which plan you're on depends on when and where you started studying, and it matters — Plan 5's £25,000 threshold is meaningfully lower than Plan 2's £29,385, so two graduates on identical salaries can have different monthly deductions purely based on their start date. 2026/27 is the first tax year Plan 5 repayments actually begin, since the plan covers courses starting from August 2023. The case people most often miscalculate is holding both an undergraduate and a postgraduate loan at once — a common situation for master's graduates. The two repayments run in parallel, each against its own threshold: 9% above the undergraduate threshold plus 6% above the £21,000 postgraduate threshold, both coming out of the same payslip. This calculator adds the postgraduate repayment on top when you tick the box, rather than replacing one with the other.

Frequently asked questions

What are the 2026/27 student loan thresholds?

Plan 1: £26,900. Plan 2: £29,385. Plan 4 (Scotland): £33,795. Plan 5: £25,000 — the first tax year Plan 5 repayments are actually due. Postgraduate Loan: £21,000, frozen for another year.

How much do I repay on a student loan?

9% of income above your plan's threshold for Plans 1, 2, 4, and 5. Postgraduate Loans repay 6% above £21,000. If you have both an undergraduate and a postgraduate loan, both percentages apply simultaneously, calculated against each loan's own threshold.

Which plan am I on?

It depends on where and when you started your course: Plan 1 for pre-2012 English/Welsh starters or any Scottish/NI student; Plan 2 for English/Welsh starters between 2012 and 2023; Plan 5 for English starters from August 2023 onward; Plan 4 for Scottish students specifically. Check your Student Loans Company account if unsure.

Does a pay rise increase my repayment a lot?

Only the amount above your threshold is charged, so a rise from £28,000 to £30,000 on Plan 2 only adds 9% of £615 (the portion crossing the £29,385 line) — about £55 a year, not 9% of the full £2,000 rise.
