Example: Plan 2 on £35,000

An annual estimate is (£35,000 − £29,385) × 9% = £505.35. If a postgraduate loan also applies, (£35,000 − £21,000) × 6% adds £840. Together that is £1,345.35 before considering payroll-period rounding or other adjustments.

Why the annual estimate differs from a payslip

Payroll uses the threshold for the relevant pay period and its deduction rules. A bonus or irregular pay can therefore create deductions that do not match a simple annual amount divided by twelve. This page explains an annual comparison, not a prediction of each payslip.

Which plan should I choose?

Use the plan confirmed by Student Loans Company or your employer’s notice. Where more than one undergraduate plan applies, payroll guidance handles the combination; a postgraduate loan can be additional. Check which repayment plan you are on rather than guessing from age alone.

Include repayments in your take-home estimate

Questions and answers

Do student loans reduce Income Tax?

Ordinary student loan repayments are deductions from pay, not a reduction of taxable pay.

Can postgraduate and undergraduate repayments apply together?

Yes. The postgraduate repayment is additional when its threshold and the relevant undergraduate threshold are exceeded.
