Common Myths About Hourly Pay and Overtime

When you're looking at a job offer or negotiating a pay rise, it's easy to fall for common misconceptions about how hourly pay relates to annual salary, especially in the finance sector. Understanding the real numbers behind your finance salary can help you make better decisions and avoid costly mistakes.

Myth 1: Your hourly rate multiplied by 40 hours and 52 weeks gives your true annual salary

Many people assume a full-time job is 40 hours per week, 52 weeks a year. In reality, most UK full-time roles are based on 37.5 hours per week (or 35 hours in some sectors). The ONS Annual Survey of Hours and Earnings (ASHE) shows median full-time weekly earnings of £766.60 in April 2025, which translates to a median annual salary of £39,039. That works out at roughly £19.67 per hour for a 37.5-hour week.

If you use 40 hours instead, you'd get a lower hourly equivalent. Always check your contract for your standard weekly hours. The rule of thumb used on Hourly to Salary is: annual ≈ hourly × hours per week × 52. For a 37.5-hour week, that's hourly × 1,950.

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

There is no legal requirement for overtime to be paid at a premium rate in the UK. While many employers offer time-and-a-half or double time, others pay only the basic hourly rate. Some jobs, particularly in finance and professional services, may not pay overtime at all – instead offering time off in lieu or expecting unpaid overtime as part of the role.

The National Minimum Wage must be paid for all hours worked, but beyond that, overtime rates are a matter of contract. When evaluating a finance salary, ask about overtime policy. The ONS low and high pay bulletin notes that 2.5% of employee jobs were paid below the NLW in April 2025, but that doesn't capture unpaid overtime.

Myth 3: London weighting is included in the hourly rate

London weighting is an additional allowance to compensate for higher living costs in the capital. It is usually paid as a separate lump sum or as an uplift to the hourly rate. For example, NHS pay scales for 2026/27 show separate High Cost Area Supplement (HCAS) rates for inner and outer London. A Band 5 nurse in inner London might receive a higher effective hourly rate than the base £16.40.

When comparing finance salaries, check whether the quoted figure includes London weighting. The ONS ASHE tables provide regional breakdowns, but the headline median figures do not separate London weighting. Always ask for a full breakdown of base pay, allowances, and any location-based supplements.

Myth 4: Annual salary is simply hourly rate × 40 × 52

As mentioned, the standard full-time week in the UK is often 37.5 hours, not 40. But there's another trap: the assumption that you are paid for 52 weeks. In reality, most employees are paid for their annual leave and bank holidays, but if you are on a zero-hours contract or work irregular hours, your annual income may be lower. The ONS ASHE annual figures are for employees who have been in the job for at least a year and include pay affected by absence.

Myth 5: All high-paying jobs are salaried, not hourly

Many senior roles in finance are salaried, but hourly pay can be very competitive. The ONS low and high pay bulletin shows that 23.2% of employee jobs were high-paid (above £25 per hour) in April 2025. Some of these are hourly positions in sectors like IT, engineering, and even some finance roles. Don't assume a salaried position is always better – an hourly role with overtime can sometimes yield a higher annual income.

Myth 6: The National Living Wage is the same for everyone

The NLW in April 2025 was £12.21 for employees aged 21 and over. But there are lower rates for younger workers: £10.00 for 18-20 year olds, £7.55 for 16-17 year olds, and £7.55 for apprentices. These rates are updated annually. For 2026/27, the NLW for 21+ rises to £12.71. If you're under 21, your finance salary expectations should reflect these legal minimums.

Myth 7: Overtime is always optional

In many contracts, overtime is voluntary, but some roles require it as part of the job. The NHS, for example, often requires staff to work additional shifts, which are paid at overtime rates. In finance, especially during reporting periods, overtime may be expected but not always compensated. Always read your contract carefully.

How to get a realistic picture of your pay

To avoid these myths, follow these steps:

1. Know your contracted hours – Check your employment contract for standard weekly hours.
2. Understand overtime policy – Ask HR or check the staff handbook for overtime rates and whether they are mandatory.
3. Factor in allowances – London weighting, shift premiums, and on-call payments can significantly boost your income.
4. Use reliable benchmarks – The ONS ASHE data and NHS pay scales are good references. For more detailed comparisons, see our salary data page.
5. Calculate your effective hourly rate – Divide your total annual earnings (including bonuses and allowances) by the total hours you actually work. This gives you a true picture.

Final thoughts

Understanding the difference between hourly and annual pay is crucial for anyone negotiating a finance salary or considering a job change. The median full-time annual salary in the UK is around £39,000, but that doesn't tell you everything. Overtime, location allowances, and contract hours all matter.
