How this is worked out
You repay 6% of your income above the threshold for your plan. The amount you owe does not change what you repay each year. Employers apply the monthly or weekly threshold each payday, so the monthly figure here is the annual amount divided by 12.
Student Finance Northern Ireland puts its borrowers on Plan 1, so a Postgraduate Loan held by someone living in Northern Ireland comes from another UK funder, such as Student Finance England. The plan follows the loan, not your address.
Northern Ireland uses the same Income Tax bands as England: 20%, 40% and 45%. Assumptions: 2026-27 thresholds, tax code 1257L, no pension or other income.
