How to Calculate My Salary: Gross Pay vs Take-Home Pay and Common Deductions

How to Calculate My Salary: Gross Pay vs Take-Home Pay

When you see a job advert offering £35,000 a year, it’s natural to wonder what that actually means for your bank account. The figure on your contract is your gross salary, but what you take home after deductions can be significantly less. Understanding the difference between gross and net pay – and the common deductions that bridge them – is essential for budgeting, negotiating a raise, or comparing job offers.

This guide explains how to calculate my salary after tax, National Insurance, pension, and student loan, using 2026/27 rates for England, Wales and Northern Ireland (with a note on Scotland).

Gross Salary vs Take-Home Pay

Gross salary is your total earnings before any deductions. Take-home pay (or net pay) is what remains after your employer deducts Income Tax and National Insurance through PAYE, plus any pension contributions, student loan repayments, or other salary sacrifice arrangements.

For a straightforward example, a gross salary of £35,000 with no pension or student loan results in:

• Income Tax: £4,486 (20% on earnings above £12,570)
• National Insurance: £1,794 (8% on earnings between £12,570 and £50,270)
• Take-home pay: £28,720 a year – that’s £2,393 a month or £552 a week.

You keep about 82p of every £1 you earn. The effective tax rate (total deductions as a share of gross pay) is roughly 18%.

Common Deductions Explained

1. Income Tax

Income Tax is charged on your earnings above the Personal Allowance (£12,570 for 2026/27). The rates are:

• Basic rate (20%): £12,571 – £50,270
• Higher rate (40%): £50,271 – £125,140
• Additional rate (45%): over £125,140

Your employer uses your tax code (usually 1257L) to apply the correct tax-free amount each pay period.

2. National Insurance (NI)

Employee National Insurance (Category A) is calculated on earnings above £12,570:

• 8% on earnings between £12,571 and £50,270
• 2% on earnings above £50,270

NI is UK-wide – the same rates apply in Scotland, Wales and Northern Ireland.

3. Pension Contributions

If you contribute to a workplace pension, the money usually comes out of your gross pay before Income Tax and NI are calculated (salary sacrifice or net pay arrangement). This means each £1 you put into your pension actually costs you less than £1 in take-home pay – a valuable tax relief.

4. Student Loan Repayments

If you have a student loan, repayments are deducted at 9% of earnings above your plan’s threshold (or 6% for Postgraduate Loans). The 2026/27 thresholds are:

• Plan 1: £26,900
• Plan 2: £29,385
• Plan 4 (Scotland): £33,795
• Plan 5: £25,000
• Postgraduate Loan: £21,000 (6% rate)

Repayments stop once the loan is cleared, but they are taken automatically through PAYE.

Scottish Income Tax

If you live in Scotland, your Income Tax is calculated using different bands set by the Scottish Parliament. The rates for 2026/27 are:

• Starter rate (19%): £12,571 – £15,397
• Basic rate (20%): £15,398 – £27,491
• Intermediate rate (21%): £27,492 – £43,662
• Higher rate (42%): £43,663 – £75,000
• Advanced rate (45%): £75,001 – £125,140
• Top rate (48%): over £125,140

National Insurance and student loan rules are the same across the UK. On a salary of £35,000, a Scottish taxpayer pays only about £15 more in Income Tax than someone in England. But from around £43,660, the 42% higher rate kicks in, meaning a Scottish earner on £50,000 takes home roughly £1,496 less per year.

How to Calculate Your Own Take-Home Pay

The easiest way to calculate my salary after all deductions is to use a take-home calculator. Simply enter your gross annual salary, choose your region, add any pension percentage and student loan plan, and the tool will show your monthly and annual net pay with a full breakdown.

You can also check your payslip: look for the gross pay figure, then subtract pre-tax deductions (like salary sacrifice pension), then statutory deductions (Income Tax, NI, student loan), and the remainder is your net pay.

Why Your Take-Home Pay Might Differ

Real-world payslips vary because of:

• Tax code adjustments: HMRC may change your code to collect underpaid tax or account for benefits in kind.
• Benefits in kind: A company car or health insurance adds notional income that increases your tax.
• Bonuses and overtime: A large bonus in one month can push you into a higher tax band for that period.
• Multiple jobs or income sources: Each employer applies tax codes based on your total income.

Always use official HMRC guidance and your own payslip for precise figures. The examples here are for planning and comparison.
