Investment Banking Salary: Separating Myth from Reality

When people talk about an investment banking salary, they often imagine six-figure annual packages straight out of university. The reality is more nuanced, especially when you consider hourly pay, overtime, and the difference between base salary and total compensation. This article uses the latest UK official data to help you understand how to convert investment banking pay into hourly and annual figures, and to bust some common myths about overtime.

What the Official Data Tells Us

The Office for National Statistics (ONS) Annual Survey of Hours and Earnings (ASHE) provides the most reliable picture of UK employee earnings. For April 2025, the median gross annual earnings for full-time employees were £39,039, and median hourly pay (excluding overtime) was £19.67. These figures cover all occupations and sectors. Investment banking is a high-paying niche, and ONS does not publish a specific category for it. However, the data for managers, directors, and senior officials shows median weekly earnings of over £1,000, which is well above the overall median.

For context, the National Living Wage (NLW) for workers aged 21 and over is £12.21 per hour (2025 rate). At a standard 37.5-hour week, that works out to about £23,809.50 per year. An investment banking salary is typically many times this, but the hours worked can also be much longer.

The Hourly-to-Annual Conversion Myth

A common myth is that you can simply multiply an hourly rate by 40 hours and 52 weeks to get an annual salary. That works for a standard full-time job, but investment banking is rarely standard. The typical conversion rule of thumb is:

Annual ≈ hourly rate × hours per week × 52 weeks

For a 37.5-hour week, that means hourly × 1,950. For a 50-hour week, it’s hourly × 2,600. If you hear an investment banking salary quoted as £70,000 base, but you work 70-hour weeks, your effective hourly rate is only about £19.23 – barely above the UK median. The myth of the huge hourly rate collapses when you factor in the long hours.

Overtime: The Big Misunderstanding

Another myth is that investment bankers are paid overtime at a premium rate (e.g., time-and-a-half). In reality, most investment banking roles are exempt from the National Minimum Wage overtime rules because they are classified as ‘highly paid’ or ‘senior’. The contract usually states a fixed annual salary with a discretionary bonus. Any extra hours are not compensated at an overtime rate – they are simply expected as part of the job. This is very different from sectors like retail or hospitality, where overtime is paid.

If you are comparing job offers, always look at the total compensation (base + bonus + benefits) and the expected hours. A lower base salary with a generous overtime policy might actually give you a better hourly rate than a high base with no overtime.

London Weighting and Regional Differences

Investment banking is heavily concentrated in London, and many firms pay a London weighting allowance. This can add 10–20% to the base salary. When converting to an hourly rate, include this allowance. For example, a £60,000 base plus £10,000 London weighting gives £70,000 annual. At 50 hours per week, that’s about £26.92 per hour. Without the weighting, it would be £23.08.

Putting It All Together

To get a true picture of an investment banking salary, you need to:

1. Know the base salary – this is the guaranteed annual amount.
2. Add any London weighting or fixed allowances.
3. Estimate your average weekly hours – be realistic, including evenings and weekends.
4. Divide by 52 weeks and then by weekly hours to get an effective hourly rate.
5. Remember that bonuses are not guaranteed – they are discretionary and can vary wildly.

For example, a first-year analyst at a top bank might have a base of £60,000, a London weighting of £10,000, and work 60 hours per week. Their effective hourly rate is (£70,000 ÷ 52 ÷ 60) = £22.44 per hour. That is above the UK median but not as glamorous as the headline £70,000 suggests.

Conclusion

The myth of the effortless high hourly rate in investment banking is just that – a myth. The long hours, lack of overtime pay, and bonus uncertainty mean that the effective hourly rate is often much lower than the annual figure implies. Always use a realistic hours assumption when converting, and check your contract for overtime and London weighting clauses. For a full breakdown of UK salary benchmarks, visit our salary data page.
