How to Calculate Salary: Advertised vs Take-Home Pay in the UK (2026/27)

Understanding Advertised Salary vs Take-Home Pay

When you see a job advert quoting a salary, that figure is your gross pay — the amount before any deductions. What lands in your bank account each month is your take-home pay (net pay), which can be significantly lower. Knowing how to calculate salary accurately from hourly rates and understand the gap between advertised and take-home is essential for budgeting and ensuring you’re paid at least the legal minimum.

Statutory Minimum Wage Rates (2026/27)

From 1 April 2026, the UK government sets the following minimum hourly rates (GOV.UK guidance):

• National Living Wage (21+): £12.71/hr
• National Minimum Wage (18–20): £10.85/hr
• National Minimum Wage (under 18): £8.00/hr
• Apprentice rate: £8.00/hr

These are the legal floors. Many employers advertise salaries above these rates, but the advertised figure is always gross.

How to Calculate Salary from Hourly Rates

To calculate salary from an hourly rate, use this formula:

Gross annual salary = hourly rate × weekly hours × 52

For example, a 40-hour week at the National Living Wage:

£12.71 × 40 × 52 = £26,436.80 per year (gross)

That works out to about £2,203 per month before deductions. For a 37.5-hour week, gross annual pay is £24,784.50 (UK Minimum Wage Calculator).

If you’re on a fixed salary rather than paid by the hour, you can reverse the calculation to check you’re above the minimum wage: divide your gross annual salary by (weekly hours × 52) to get your equivalent hourly rate. This is especially important if you work unpaid overtime.

Take-Home Pay: What You Actually Receive

Your employer deducts the following from your gross pay through PAYE:

• Income Tax: 20% on earnings above the Personal Allowance of £12,570 (for 2026/27 in England, Wales, and NI). Higher rates apply above £50,270.
• National Insurance: 8% on earnings between £12,570 and £50,270, then 2% above that.
• Pension contributions: If you’re enrolled in a workplace pension, your contribution (typically 5% of qualifying earnings) is taken before tax.
• Student loan repayments: 9% of earnings above your plan’s threshold, plus 6% above £21,000 for a Postgraduate Loan (WorkCalc).

Using the GovMath example for a gross salary of £35,000, take-home is about £28,720 per year — roughly 82% of gross. For someone on the National Living Wage (40 hours), take-home is approximately £22,555 per year or £1,880 per month (UK Minimum Wage Calculator).

Practical Steps to Calculate Your Take-Home Pay

1. Start with your gross pay — your salary plus any bonuses, overtime, or commission.
2. Subtract salary sacrifice — pension contributions made via salary sacrifice reduce the income you pay tax and NI on.
3. Apply Income Tax — deduct your Personal Allowance, then tax the remainder at the appropriate rate.
4. Apply National Insurance — calculate 8% on earnings between £12,570 and £50,270, and 2% above that.
5. Subtract student loan repayments if applicable.
6. The result is your annual take-home pay. Divide by 12 for monthly net pay.

Common Pitfalls in Minimum Wage Compliance

Even if your advertised salary looks healthy, you could still be underpaid the minimum wage. Here’s why:

• Unpaid extra hours: If you regularly work beyond your contracted hours without pay, your average hourly rate may fall below the statutory minimum.
• Salary sacrifice schemes: Deductions for childcare vouchers, cycle-to-work, or additional pension contributions can reduce your pay for minimum wage purposes. The NHS Employers guidance warns that employers must check these arrangements don’t push pay below the legal floor.
• Excluded payments: Tips, overtime premiums, allowances, and benefits in kind do not count as pay for minimum wage calculations (GOV.UK guidance). If your employer includes these in your headline rate, your actual hourly pay could be lower than you think.

Always review your payslip and use the official GOV.UK method to calculate salary for minimum wage: divide your total qualifying pay by the total hours worked in the pay reference period. If the result is below the relevant rate, your employer must top up your pay.

Why This Matters for Job Seekers

When comparing job offers, don’t just look at the advertised salary. Consider:

• Contracted hours — a higher hourly rate with fewer hours may give less annual income than a lower rate with full-time hours.
• Pension contributions — employer contributions are part of your total compensation but don’t affect take-home.
• Overtime policy — if overtime is unpaid, your effective hourly rate drops.
• Location — average earnings vary by region; the ONS Average Weekly Earnings report shows total pay averaging £745/week nationally, but London and the South East are higher.

Final Thoughts

Understanding the difference between advertised salary and take-home pay helps you make informed career decisions and ensures you’re not being underpaid. Always calculate salary using both gross and net figures, and check your employer complies with minimum wage law. The statutory rates are a safety net, but many workers are entitled to more — especially if they’re covered by the voluntary Real Living Wage, which is typically higher.
