How this was worked out

1. Salary: £30,000
2. Personal allowance: £12,570. Payroll applies it as tax code 1257L, which gives £12,579 of tax-free pay.
3. Taxable income: £30,000 − £12,579 = £17,421
4. Basic rate: £17,421 × 20% = £3,484.20
5. Income tax: £3,484.20
6. National Insurance: (£30,000 − £12,570) × 8% = £1,394.40
7. Student loan (Plan 2): (£30,000 − £29,385) × 9% = £55.35, rounded down to £55
8. Take-home pay: £30,000 − £3,484.20 − £1,394.40 − £55 = £25,066.40

What the calculator assumes

• The 2026/27 tax year.
• You are employed and your loan is repaid through your employer's payroll.
• The salary you enter is your pay before tax, and it stays the same all year.
• You have one undergraduate plan. Some people have loans on two plans at once, which this calculator does not cover.
• The sums are worked out for the whole year at once. Your employer works out each payslip on its own, so a month can be a few pence different.

How it is worked out

Each repayment is a share of your pay above the threshold for your plan. For the 2026/27 tax year the rate is 9% and the thresholds are £26,900 for Plan 1, £29,385 for Plan 2, £33,795 for Plan 4 and £25,000 for Plan 5.

A postgraduate loan is a separate loan with its own rule. It is repaid at 6% of pay above £21,000. If you have a postgraduate loan and an undergraduate plan, both repayments are taken and added together.

Your employer takes the repayment from your pay along with income tax and National Insurance. It checks your pay against a weekly or monthly share of the threshold, so a bonus or overtime can cause a repayment in a month when your yearly pay is under the threshold. You can ask for a refund at the end of the tax year if that happens.

The amount you owe does not change what you repay each year. The student loan thresholds page lists the figures for each plan.

Your plan depends on where you applied for your loan and when your course started. Loans from Student Finance Northern Ireland are on Plan 1, as are the oldest loans from England and Wales. Newer undergraduate loans from Wales are on Plan 2. In England, Plan 2 covers the courses between the Plan 1 and Plan 5 periods, and Plan 5 covers the most recent undergraduate courses. Loans from the Student Awards Agency Scotland are on Plan 4. You cannot choose your plan, and your online account with the Student Loans Company shows which one you are on.

Every rate on this page comes from GOV.UK. The sources page lists each one with a link to where we found it and the date we checked it. The methodology page explains the rounding and the other choices behind the sums. The take-home pay calculator shows the repayment beside income tax, National Insurance and pension.

What it leaves out

• Interest. Interest is added to your balance each year, and the rate depends on your plan. It adds to what you owe. The monthly repayment stays the same.
• Write-off dates. Each plan is cancelled after a set time. The calculator does not show how long you repay for.
• Self-employed income. If you are self-employed, or you send a Self Assessment tax return for another reason, repayments on that income are worked out in the return.
• Life overseas. If you leave the UK for a long time, you repay the Student Loans Company direct. The thresholds depend on the country you live in.
