Gross vs Net Pay: How to Use a Net Salary Calculator UK for 2026/27

Understanding Gross vs Net Pay: What a Net Salary Calculator UK Reveals

When you see a job advert offering £35,000 a year, it is natural to wonder how much of that actually reaches your bank account. The difference between gross salary (the advertised figure) and net salary (your take-home pay) is made up of several deductions that every UK employee should understand. Using a net salary calculator UK is the quickest way to see exactly where your money goes.

What Deductions Are Taken from Your Gross Salary?

Your employer starts with your gross pay and then removes:

• Income Tax – calculated on earnings above your Personal Allowance.
• National Insurance – a separate charge on your earnings between certain thresholds.
• Pension contributions – if you are enrolled in a workplace pension, your share is deducted before or after tax depending on the scheme.
• Student loan repayments – if you have a student loan, a percentage of your earnings above a threshold is taken.

Each deduction is worked out independently, so they do not stack on top of each other. You can add them up to see your total deductions.

Income Tax Rates for 2026/27

For the 2026/27 tax year, the Personal Allowance remains at £12,570, meaning you pay no tax on the first £12,570 you earn. Above that, the rates are:

• Basic rate (20%) – on earnings from £12,571 to £50,270.
• Higher rate (40%) – on earnings from £50,271 to £125,140.
• Additional rate (45%) – on earnings over £125,140.

These rates apply in England, Wales and Northern Ireland. Scotland has its own bands, which we cover later.

National Insurance Contributions

Employee National Insurance is charged on your earnings above the Primary Threshold of £12,570. The rates for 2026/27 are:

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

Unlike Income Tax, National Insurance is calculated per pay period, not annually. It stops once you reach State Pension age.

Example: £35,000 Salary

Let us take a typical salary of £35,000. With no pension or student loan, and using the standard 1257L tax code:

• Income Tax: 20% of £22,430 (earnings above £12,570) = £4,486.
• National Insurance: 8% of £22,430 = £1,794.40.
• Take-home pay: £35,000 – £4,486 – £1,794.40 = £28,719.60 per year, or £2,393.30 per month.

That means you keep about 82p of every pound you earn.

How Pension Contributions Affect Take-Home Pay

If you are enrolled in a workplace pension, your contribution is deducted from your gross salary. For example, a 5% employee contribution on £35,000 reduces your gross pay for tax and NI purposes (if done via salary sacrifice) or is taken after tax (relief at source). Using a typical 5% contribution, your take-home pay drops to around £27,320 per year, as shown by salary data from common calculators.

Student Loan Repayments

If you have a student loan, an additional deduction applies once your earnings exceed the repayment threshold for your plan. The thresholds for 2026/27 are:

• Plan 1: £26,900 – repay at 9%.
• Plan 2: £29,385 – repay at 9%.
• Plan 4 (Scotland): £33,795 – repay at 9%.
• Plan 5: £25,000 – repay at 9%.
• Postgraduate Loan: £21,000 – repay at 6%.

For someone on Plan 2 earning £35,000, the repayment would be 9% of (£35,000 – £29,385) = £505.35 per year, reducing monthly take-home by about £42.

Scottish Income Tax Differences

If you live in Scotland, your Income Tax is calculated using different bands. For 2026/27, the Scottish rates are:

• Starter rate (19%) – on earnings from £12,571 to £14,876.
• Basic rate (20%) – on earnings from £14,877 to £26,561.
• Intermediate rate (21%) – on earnings from £26,562 to £43,662.
• Higher rate (42%) – on earnings from £43,663 to £125,140.
• Top rate (48%) – on earnings over £125,140.

On a salary of £35,000, a Scottish taxpayer pays about £4,547 in Income Tax – roughly £61 more than in the rest of the UK. National Insurance remains the same UK-wide.

Common Questions About Gross and Net Pay

What is the median full-time salary in the UK? According to ONS ASHE data, the median full-time gross annual pay is around £39,039. After tax and NI, that works out to roughly £2,636 per month take-home for a standard employee.

How does the National Living Wage affect take-home pay? For workers aged 21 and over, the National Living Wage is £12.71 per hour for 2026/27. Based on a 37.5-hour week, that gives a gross annual salary of about £24,785. After deductions, monthly take-home is approximately £1,780.

What if my tax code is different? Your tax code adjusts your Personal Allowance. A non-standard code (e.g., K codes or reduced allowances) will change your monthly tax deduction. Always check your payslip and use a calculator that allows custom tax codes.
