Common Myths About Hourly Pay and Overtime

Understanding how hourly rates translate into annual salary is essential for UK employees and job seekers. Yet many people rely on oversimplified rules of thumb or believe common myths that can lead to confusion during job offers, pay negotiations, or budget planning. This article uses the latest official data from the Office for National Statistics (ONS) and NHS pay scales to set the record straight – and shows how our salary calulator can help you get accurate conversions.

Myth 1: Overtime Is Always Paid at Time-and-a-Half

Many assume that any hour worked beyond the standard week automatically attracts a premium rate. In reality, overtime pay depends on your contract. Some roles – especially in retail, hospitality, or care – pay only the basic hourly rate for extra hours, while others may offer time-and-a-half or double time only after a certain threshold. The ONS Annual Survey of Hours and Earnings (ASHE) distinguishes between basic pay and overtime pay, but the median figures for 2025 show that overtime makes up a relatively small share of total earnings for most full-time employees. Always check your contract or collective agreement rather than assuming a premium.

Myth 2: Hourly Rate × 37.5 Hours × 52 Weeks Equals Your Exact Annual Salary

This formula is a useful starting point, but it can be misleading. The ONS ASHE 2025 report notes that median gross annual earnings for full-time employees were £39,039, while median hourly earnings (excluding overtime) were £19.67. Multiplying £19.67 by 37.5 hours and 52 weeks gives £38,361 – close but not identical. Why the difference? ASHE annual figures include employees who have been in the same job for at least a year and may include pay during absence (e.g., parental leave). Also, many roles have contracted hours different from 37.5 (e.g., 35, 40, or shift-based). Our salary data page provides benchmarks for various occupations, but always use your actual contracted hours and check for any London weighting or other allowances.

Myth 3: The National Living Wage Covers All Low-Paid Workers

The National Living Wage (NLW) applies to employees aged 21 and over – it was £12.21 per hour in April 2025. However, younger workers (18–20) are entitled to the National Minimum Wage of £10.00, and those aged 16–17 receive £7.55. Apprentices have their own rate. The ONS Low and High Pay bulletin for 2025 shows that 2.5% of employee jobs were paid below the NLW/NMW, but this is not a measure of non-compliance because some deductions (e.g., for accommodation) are legal. If you are offered a rate near the NLW, verify your age group and check whether your employer is following the correct band.

Myth 4: London Weighting Is Always Included in Advertised Hourly Rates

Many job adverts in London or the South East mention a ‘London weighting’ or ‘High Cost Area Supplement’ (HCAS). For NHS staff, for example, the 2026/27 pay scales include separate hourly values for inner and outer London. A Band 5 nurse might see a base hourly rate of £16.40, but with HCAS the rate could be higher. However, not all employers include weighting in the headline figure. Always read the full job description or ask during the interview. Our salary calulator allows you to add a London weighting factor if you know the amount.

Myth 5: Annual Salary Is Always Better Than Hourly Pay

Some job seekers assume a salaried position is more stable or higher paid than an hourly role. In reality, hourly workers may earn more if they regularly receive overtime, shift premiums, or tips. Conversely, salaried employees often have guaranteed minimum hours and paid holiday. The ONS data shows that median weekly earnings for full-time employees were £766.60 in April 2025, but part-time hourly rates can be competitive in sectors like tech or skilled trades.

How to Use Our Salary Calulator

Our salary calulator converts an hourly rate to an annual salary using the standard assumption of 37.5 hours per week and 52 weeks per year. You can adjust the hours per week to match your contract. The result is a gross annual figure before tax and National Insurance. Remember that actual take-home pay depends on your tax code, pension contributions, and any salary sacrifice arrangements.
