Gross vs Net Pay: What your payslip actually means

If you've ever been offered a salary and then wondered why your bank account receives noticeably less, you're not alone. The gap between gross pay and net pay is where income tax, National Insurance, pension contributions and other deductions live. Understanding that gap makes it easier to budget, negotiate and spot errors.

Gross pay: the headline number

Gross pay is the amount you earn before any deductions. If your contract says £35,000 a year, that's your gross salary. If your payslip shows £2,800 for the month, that's your gross monthly pay. It's the number everyone quotes, but it's not the number that lands in your account.

Net pay: what you actually receive

Net pay is your take-home pay — the amount after all deductions. This is the figure that matters for rent, mortgages, groceries and savings. Two people with the same gross salary can have different net pay if one pays into a pension, has a student loan, or earns enough to tip into a higher tax band.

What gets taken out of gross pay

For most employees in England, Wales and Northern Ireland, the main deductions are:

• Income Tax — calculated on your taxable income after the personal allowance. For 2026/27 the personal allowance is £12,570. Basic rate tax is 20%, higher rate is 40%, and additional rate is 45%.
• National Insurance — a separate contribution based on earnings. For 2026/27 most employees pay 8% on earnings between roughly £12,570 and £50,270, and 2% above that.
• Pension contributions — money you pay into a workplace or personal pension. These often come out before tax (net pay) or after tax with basic-rate relief added (relief at source).
• Student loan repayments — deducted once earnings pass the threshold for your plan. Plans 1, 2, 4, 5 and Postgraduate each have different thresholds and rates.
• Other deductions — such as cycle-to-work schemes, childcare vouchers, union fees or share-save plans.

Scottish taxpayers use different income tax bands, so the split between tax and take-home can look different even with the same gross pay.

A simple worked example

Say you earn £32,000 a year in England and pay 5% into a workplace pension through net pay.

• Gross salary: £32,000
• Pension contribution: £1,600
• Taxable income: £30,400
• Income tax: roughly £3,566
• National Insurance: roughly £2,554
• Estimated net pay: around £25,280 a year, or about £2,107 a month

The exact figures depend on your tax code, whether you have a student loan, and how your pension relief is applied. Use it as a sense-check rather than a payslip replacement.

How to calculate your own net wages

The quickest way is to use a reliable take-home pay calculator. Enter your gross salary, pension contribution, student loan plan and any other deductions, and it will do the rest.

If you want to do it manually, the steps are:

1. Start with your gross salary.
2. Deduct any pre-tax contributions, such as a net-pay pension.
3. Subtract your personal allowance to find your taxable income.
4. Apply the income tax bands.
5. Calculate National Insurance on your gross earnings.
6. Deduct any other fixed amounts, such as student loan or cycle-to-work.

Most people use a calculator because the bands and thresholds change most years, and it's easy to miss the tapered personal allowance above £100,000 or the High Income Child Benefit Charge between £60,000 and £80,000.

Why your payslip might look wrong

• Emergency tax code — common when starting a new job. It usually sorts itself within a month or two, but check it.
• Wrong tax code — if HMRC has you on a code that doesn't match your situation, you'll overpay or underpay.
• Benefit in kind — a company car or private medical insurance can reduce your personal allowance or increase taxable pay.
• Multiple jobs — each job may use a different tax code, and the combined income can push you into a higher band.

When to get help

For most people, gross and net pay are straightforward once you know what the deductions are. If your affairs are more complex — multiple income sources, share schemes, Scottish tax bands, or earnings near £100,000 — a bit of extra checking pays off.
