How much is my Plan 1 student loan repayment on a £45,000 salary?
On a £45,000 salary in 2026/27, a Plan 1 student loan repayment is £1,629 for the year (9% of the £18,100 above the £26,900 threshold), leaving take-home pay of £34,290.60 a year after Income Tax, National Insurance and the loan repayment -- about £2,857.55 a month.
Full answer
Plan 1 student loans are repaid at 9% of income above a 2026/27 threshold of £26,900. On a £45,000 salary, the amount above the threshold is £18,100, so the annual repayment is 9% of £18,100, which is £1,629, or £135.75 a month, deducted automatically through PAYE. The underlying Income Tax on £45,000 is £6,486 (20% of the £32,430 taxable after the £12,570 Personal Allowance) and National Insurance is £2,594.40 (8% of the same £32,430), so total deductions are £10,709.40, leaving take-home pay of £34,290.60 a year, around £2,857.55 a month. Salary sacrifice pension contributions reduce your gross pay for National Insurance and student loan purposes as well as Income Tax, so increasing pension contributions via salary sacrifice can lower the Plan 1 repayment alongside the tax saving.
