Why Salary Comparison Matters

When you’re weighing up a job offer, it’s not always easy to compare an hourly wage with a salaried position. A role that pays £12.50 an hour might look modest, but if it includes overtime, a pension, and London weighting, the total package could rival a £30,000 salary. Conversely, a £40,000 annual salary might seem generous until you realise it expects 50-hour weeks with no overtime pay. That’s why a careful salary comparison is essential for UK job seekers and employees.

This article uses the latest official data from the Office for National Statistics (ONS), the National Living Wage, and public sector pay scales to help you make informed comparisons between hourly and annual pay.

UK Earnings Benchmarks from the ONS

The ONS Annual Survey of Hours and Earnings (ASHE) for 2025 provides the most authoritative snapshot of UK pay. For full-time employees:

• Median weekly earnings: £766.60 (up 5.3% from £728.27 in 2024)
• Median gross annual earnings: £39,039 (up 4.3% from £37,439)
• Median hourly earnings (excluding overtime): £19.67 (up 5.4% from £18.66)

These figures are for employees who have been in the same job for at least a year, so they reflect established pay rather than starting salaries. Part-time median weekly earnings were £280.00, a 6.4% increase.

Low and High Pay Thresholds

The ONS also defines low pay as less than two-thirds of median hourly pay, and high pay as more than 1.5 times the median. In April 2025:

• Low-pay threshold: £11.97 per hour
• High-pay threshold: £26.94 per hour

Only 2.5% of employee jobs were low-paid in 2025, the lowest proportion since records began in 1997. Meanwhile, 23.2% of jobs were high-paid. These thresholds are useful when comparing an hourly rate against the national distribution.

National Living Wage and Minimum Wage

The government sets legal minimum hourly rates that apply to most workers. For April 2025:

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

From April 2026, the NLW for those aged 21+ rises to £12.71 per hour. Many jobs, especially in retail, hospitality, and care, cluster around these rates. When comparing an hourly job at the NLW with a salaried role, remember that the annual equivalent at 37.5 hours per week is about £23,810 (2025 rate) or £24,785 (2026 rate). That’s well below the median full-time salary of £39,039, but some roles offer progression or additional payments.

NHS Pay Scales as a Public Sector Example

Public sector pay scales provide a clear structure for comparing hourly and annual pay. The NHS Employers published 2026/27 pay scales effective from 1 April 2026. Key bands for new starters:

• Band 5 (entry): £38,488 annual / £19.68 hourly
• Band 5 (mid): £41,511 annual / £21.23 hourly
• Band 5 (top): £46,852 annual / £23.96 hourly
• Band 6 (entry): £47,951 annual / £24.52 hourly

These rates include the basic pay but not the High Cost Area Supplements (HCAS) for London and surrounding areas. For example, an inner London HCAS of 20% of basic salary (with a minimum of £5,794 and maximum of £8,746) can add several thousand pounds. When comparing an NHS hourly rate with a private sector salary, always check whether London weighting or other allowances are included.

Converting Hourly to Annual: The Formula and Its Limits

The standard conversion used by many job sites is:

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

For a typical full-time role of 37.5 hours per week:

• £12.21/hr → £23,809.50 per year
• £19.67/hr → £38,356.50 per year (close to the ONS median)
• £24.52/hr → £47,814 per year

But this formula assumes a steady 52-week year with no unpaid overtime, no variable hours, and no salary sacrifice. In reality:

• Overtime: Many hourly jobs pay time-and-a-half or double time for extra hours, which can boost annual income significantly. Salaried roles often include overtime unpaid or at a lower rate.
• Holiday pay: Hourly workers may receive rolled-up holiday pay or separate holiday pay; salaried employees typically get paid leave included.
• London weighting: As seen with NHS HCAS, location supplements can add 15–20% to base pay.
• Pension and benefits: A lower salary with a generous employer pension contribution might be worth more than a higher salary with a minimal pension.

Tips for a Fair Salary Comparison

1. Always compare total compensation, not just base pay. Include pension contributions, bonus potential, overtime rates, and any allowances.
2. Use the ONS median as a benchmark but adjust for your occupation and region. For example, median pay in London is higher than the national average.
3. Check the contract for guaranteed hours. A zero-hours contract at £15 per hour might yield less annual income than a 37.5-hour contract at £12 per hour.
4. Consider job security and progression. Public sector roles like the NHS offer incremental pay rises and defined benefit pensions, which can outweigh a slightly higher hourly rate in the private sector.
5. Use our tools to run your own calculations: the Hourly to Salary converter lets you test different hours and rates, and our salary data page provides regional and occupational breakdowns.

Conclusion

Making a meaningful salary comparison between hourly and annual pay in the UK requires more than a simple multiplication. By using official benchmarks from the ONS, the National Living Wage, and public sector pay scales like the NHS, you can see where a job offer sits relative to the national average. Always factor in overtime, location allowances, and benefits. For more detailed analysis, explore our salary articles and topics pages.
