Plan 4 is the repayment plan for Scottish student loans funded by the Student Awards Agency Scotland (SAAS). Like the other income-contingent plans, it only takes repayments once you earn above a set threshold, and the amount is a fixed percentage of the income above that line — never a percentage of your whole salary.
For 2026/27 the Plan 4 threshold is £32,745 a year (about £2,728.75 a month or £629.71 a week). You repay 9% of everything you earn above it. If your income drops below the threshold — for example during a gap between jobs — repayments simply stop until you earn over it again.
If you have more than one student loan plan running at once, or also have a Postgraduate Loan, the deductions stack — the student loan repayment calculator handles several plans together.
Plan 4 has the highest repayment threshold of the 9% plans, which means Scottish graduates start repaying later than those on Plan 1, Plan 2 or Plan 5. The trade-off is that Plan 4 loans, like Plan 1, do not have the long 40-year write-off of Plan 5. If you are on a different plan, see the Plan 2 calculator or the Plan 5 calculator.
The 2026/27 Plan 4 threshold is £32,745 a year. You repay 9% of income above it. Plan 4 applies to Scottish (SAAS) loans.
You earn £7,255 above the threshold, so 9% is about £652.95 a year — roughly £54 a month through PAYE.
