Comparing Hourly and Salaried Offers: A Guide to Salary Calculation in the UK

Median full-time annual earnings in the UK were £39,039 in April 2025, equivalent to roughly £19.67 per hour for a standard 37.5-hour week.

Why Compare Hourly and Salaried Offers?

When you're job hunting or considering a change, you'll often see roles advertised as either an hourly rate (common in retail, hospitality, and healthcare) or an annual salary (typical in professional and office-based jobs). Making a fair comparison requires a clear salary calculation that accounts for working hours, overtime, location allowances, and benefits. This guide uses the latest UK data to help you evaluate offers side by side.

The Standard Conversion Formula

The simplest way to compare is to convert an hourly rate into an annual figure. Most full-time roles in the UK are based on a 37.5-hour week (though some use 35, 37, or 40 hours). The formula is:

Annual salary ≈ hourly rate × hours per week × 52 weeks

For a 37.5-hour week, that's hourly rate × 1,950 hours per year. For example, the National Living Wage of £12.21 per hour (April 2025 rate) gives roughly £23,809.50 per year. But this is a baseline – actual pay may differ due to unpaid overtime, shift premiums, or salary sacrifice arrangements.

UK Benchmarks from ONS ASHE

The Office for National Statistics' Annual Survey of Hours and Earnings (ASHE) provides the most authoritative picture. In April 2025, median gross annual earnings for full-time employees were £39,039, and median hourly earnings (excluding overtime) were £19.67. That means half of full-time workers earn more than this, half less. For part-time employees, the figures are lower, but ASHE focuses mainly on full-time roles.

ASHE also defines low pay and high pay. Jobs paying less than £11.97 per hour (two-thirds of the median) are considered low-paid – just 2.5% of jobs fell into this category in 2025. Jobs paying more than £26.94 per hour (1.5 times the median) are high-paid, accounting for 23.2% of jobs. These thresholds are useful when comparing an hourly offer against the national distribution.

National Living Wage and Minimum Wage

For the lowest-paid roles, the legal minimums set by GOV.UK are crucial. In April 2025:

  • National Living Wage (21+): £12.21 per hour
  • National Minimum Wage (18–20): £10.00 per hour
  • National Minimum Wage (16–17): £7.55 per hour
  • Apprentice rate: £7.55 per hour

When comparing a salaried offer to an hourly job, check that the hourly equivalent (using the formula above) meets or exceeds these minimums. Some employers pay above the minimum, especially in sectors with labour shortages.

Example: NHS Pay Scales

The NHS is one of the UK's largest employers and uses structured pay bands. For 2026/27, NHS Employers published rates including Higher Cost Area Supplements (HCAS) for London and surrounding areas. Key hourly rates (inclusive of HCAS where applicable) include:

  • Band 5 (newly qualified nurses, etc.): £16.40 per hour
  • Band 6 (specialist nurses, paramedics): £20.44 per hour

These rates already include the HCAS uplift, which can be 20% of basic salary (subject to a minimum of £5,794 and maximum of £8,746 per year). If you're comparing an NHS salaried role with an hourly job elsewhere, remember that NHS roles also come with a generous pension, sick pay, and holiday entitlement – factors that a simple hourly-to-annual conversion doesn't capture.

London Weighting and Location Allowances

Many hourly jobs in London and the South East include a location allowance. For example, the NHS HCAS adds thousands to annual pay. Private sector roles may have similar

FAQs

How do I convert an hourly rate to an annual salary?

To convert an hourly rate to an annual salary, multiply the hourly rate by the number of hours worked per week and then by 52 weeks. For a standard full-time week of 37.5 hours, the formula is: annual salary ≈ hourly rate × 37.5 × 52. For example, at the National Living Wage of £12.21 per hour, this gives approximately £23,809.50 per year. Remember that this assumes no unpaid overtime, consistent hours, and does not account for holiday pay or benefits.

What is the difference between the National Living Wage and the National Minimum Wage?

The National Living Wage (NLW) is the minimum hourly rate for employees aged 21 and over, set by the government. In April 2025 it was £12.21 per hour. The National Minimum Wage (NMW) applies to younger workers: £10.00 per hour for ages 18–20, and £7.55 per hour for ages 16–17. Apprentices also have a separate rate of £7.55 per hour. Both are legal minimums; many employers pay more.

How do London weighting and overtime affect salary calculation?

London weighting (or Higher Cost Area Supplements, HCAS) is an additional payment added to base pay for jobs in high-cost areas, particularly London and the South East. For example, NHS pay scales include HCAS that can add 20% of basic salary (subject to minimum and maximum payments). Overtime is typically paid at a higher rate (e.g., time-and-a-half) and should be included separately when comparing total earnings. When converting an hourly rate to an annual salary, ensure you use the base rate excluding overtime and add any location supplements separately.
