How much is my Plan 2 student loan repayment on a £100,000 salary?
On a £100,000 salary in 2026/27, a Plan 2 student loan repayment is £6,355.35 for the year (9% of the £70,615 above the £29,385 threshold), leaving take-home pay of £62,202.05 a year after Income Tax, National Insurance and the loan repayment -- about £5,183.50 a month.
Full answer
Plan 2 student loans are repaid at 9% of income above a 2026/27 threshold of £29,385. On a £100,000 salary, the amount above the threshold is £70,615, so the annual repayment is 9% of £70,615, which is £6,355.35, or £529.61 a month, deducted automatically through PAYE. The underlying Income Tax on £100,000 is £27,432 (£7,540 at 20% on the first £37,700 of taxable income, plus £19,892 at 40% on the remaining £49,730, with the Personal Allowance not yet tapered at exactly £100,000) and National Insurance is £4,010.60 (£3,016 at 8% up to the Upper Earnings Limit, plus £994.60 at 2% above it), so total deductions are £37,797.95, leaving take-home pay of £62,202.05 a year, around £5,183.50 a month. Earn one pound more than £100,000 and the Personal Allowance starts tapering, adding an effective 60% marginal Income Tax rate on top of the 9% student loan repayment and 2% National Insurance -- a combined 71% marginal deduction rate that many higher earners manage through additional pension contributions.
