Common Myths About Hourly Pay and Overtime

Many UK employees and job seekers assume that converting an hourly rate to an annual salary is a simple multiplication, or that overtime always pays time-and-a-half. These assumptions can lead to misunderstandings about your true earnings, especially when you factor in schemes like a salary sacrifice electric car scheme. Let’s separate fact from fiction using the latest official data.

Myth 1: Your hourly rate is just your annual salary divided by 52 weeks and 37.5 hours

It’s a useful rule of thumb: annual salary ≈ hourly rate × hours per week × 52. But this ignores unpaid breaks, unpaid overtime, and salary sacrifice deductions. According to the ONS ASHE 2025, median full-time gross annual earnings were £39,039, which at 37.5 hours per week gives an implied hourly rate of about £20.02. However, the actual median hourly pay (excluding overtime) was £19.67. The difference comes from unpaid overtime and the fact that some employees work more than their contracted hours without extra pay.

When you join a salary sacrifice electric car scheme, your gross pay is reduced by the lease cost before tax and National Insurance. This means your taxable annual salary drops, and your effective hourly rate for National Minimum Wage purposes also drops. The scheme must ensure your pay after sacrifice stays above the National Living Wage (£12.71 per hour from April 2026). For example, an NHS Band 3 employee earning £25,760 annually (hourly £13.17) could sacrifice only a limited amount before hitting the NLW floor.

Myth 2: Overtime is always paid at time-and-a-half

Overtime rates vary widely. In the NHS Agenda for Change contract, overtime on weekdays is typically paid at time-and-a-half, but many private-sector roles pay only your basic hourly rate for extra hours, or offer time off in lieu. The ONS ASHE data shows that median weekly earnings for full-time employees rose 5.3% in 2025, partly driven by increased overtime in caring and leisure occupations. But that doesn’t mean everyone gets a premium.

If you’re considering a salary sacrifice electric car scheme, remember that overtime pay is usually included in your gross salary for sacrifice calculations. However, if your overtime is irregular, the scheme may base your affordability on your basic pay only. Always check with your payroll department.

Myth 3: Salary sacrifice doesn’t affect your pension or holiday pay

This is partly true but depends on your employer. The NHS Electric Car Scheme guide states that in most well-designed NHS schemes, your pensionable pay is protected – contributions are calculated on your pre-sacrifice salary. However, not all employers do this. If your pension is based on your reduced salary, your retirement savings could be lower. Similarly, holiday pay (statutory minimum 5.6 weeks) is usually calculated on your normal pay, but salary sacrifice can reduce the reference period for averaging.

For NHS staff, the NHS Employers pay scales for 2026/27 show that basic pay ranges from £25,272 (Band 1, closed to new entrants) to over £39,959 (Band 6). A Band 5 nurse earning £32,073 annually (£16.40 per hour) could sacrifice around £2,000–£3,000 per year for an electric car lease without breaching the NLW, while still protecting their pension. But higher-rate taxpayers (Band 8a and above) get up to 42% tax and NI relief on the sacrificed amount.

Myth 4: London weighting is just a bonus, not part of your hourly rate

London weighting (or Higher Cost Area Supplements in the NHS) is an annual allowance added to your base salary. For example, an NHS Band 6 in inner London receives a higher annual rate than the national figure. When calculating your effective hourly rate for overtime or salary sacrifice limits, you should include the weighting. The NHS Employers pay scales show both annual and hourly rates inclusive of HCAS. Ignoring this can lead to underestimating your true hourly value.

Myth 5: The National Living Wage is the same for everyone

The NLW for workers aged 21 and over was £12.21 per hour in April 2025, rising to £12.71 in April 2026. But younger workers (18–20) are entitled to a lower National Minimum Wage of £10.00 (2025), and apprentices get £7.55. If you’re on a salary sacrifice electric car scheme, the NLW floor applies to your age group. For a 21-year-old NHS Band 2 worker earning £12.92 per hour (Band 1 rate, closed to new entrants), even a small sacrifice could push them below the NLW, so the scheme must cap the deduction.

Putting it all together: hourly to annual conversion with salary sacrifice

To estimate your take-home pay under a salary sacrifice arrangement, start with your gross annual salary (including any London weighting). Divide by 52 weeks and your contracted weekly hours to get your base hourly rate. Then subtract the annual sacrifice amount, and check that the resulting hourly rate is at least the NLW. Finally, apply tax and NI relief (typically 28% for basic-rate taxpayers, 42% for higher-rate). The NHS Electric Car Scheme guide illustrates that a Band 6 employee on £39,959 could save up to 50% compared to a personal lease, thanks to the 4% BiK rate on electric cars.

Key takeaways

• Hourly rate ≠ annual ÷ 52 ÷ hours – unpaid overtime and salary sacrifice change the effective rate.
• Overtime rates vary – don’t assume time-and-a-half without checking your contract.
• Salary sacrifice can affect NLW compliance – especially for lower-paid workers.
• London weighting counts – include it in your hourly rate calculations.
• Pension protection is not automatic – confirm with your employer before joining a salary sacrifice scheme.

Understanding these myths helps you make informed decisions about your pay and benefits, whether you’re negotiating a raise, considering overtime, or exploring a salary sacrifice electric car scheme.
