Investment banking is hard because it combines extreme hours, high-stakes decision-making, and constant pressure to bring in money for the firm
The difficulty in investment banking comes from three sources that hit at the same time: the work itself is technically complex, the environment is intensely competitive, and the schedule is brutal. A junior banker might work 80 to 100 hours a week during deal cycles, meaning you build financial models at 2 a.m., present to clients at 8 a.m., and do it again the next day. The work requires you to absorb dense financial concepts quickly, spot errors that cost millions, and explain your thinking to senior bankers who will challenge every number. At the same time, your value to the firm depends on your ability to help land new clients and close deals—something that takes years to learn and months to see pay off.
The difficulty is not evenly distributed. Your first two years as an analyst are the hardest in terms of pure workload and the steepness of the learning curve. After that, the work becomes more strategic and less mechanical, but the pressure to produce revenue grows. If you move into a specialized group like mergers and acquisitions or leveraged finance, the deal cycles can be unpredictable—you might have three weeks of normal hours followed by six weeks where you sleep at the office.
Key Takeaways
- Investment banking analysts work 80 to 100 hours per week during active deal cycles, with no predictable schedule and frequent all-nighters.
- The technical skills—building financial models, valuing companies, structuring deals—take months to learn and years to master, and mistakes are expensive.
- Your success depends partly on work quality and partly on your ability to build client relationships and help the firm win new business, which is harder to control.
- Burnout is common in the first two years; many people leave after their analyst contract ends because the hours and pressure do not match their goals.
- Compensation is high relative to other entry-level jobs, but the hourly rate during busy periods is often lower than jobs with normal schedules.
The Schedule and What It Actually Means
Investment banking hours are not a myth or exaggeration—they are structural. During a deal, you are on call. A client might request updated financial projections at 6 p.m., which means you work until midnight to deliver them. The senior banker then reviews your work at 1 a.m., sends back comments, and you revise until 4 a.m. You shower, change clothes, and are back in the office by 8 a.m. for a client call. This happens multiple times per week during active deal cycles, which can last months.
The schedule is also unpredictable. You cannot plan your personal life around banking hours the way you can with a 9-to-5 job. Weekends are not may provide off. Vacations are interrupted by deal emergencies. If you have family obligations, a partner, or health issues that require consistent sleep, investment banking makes all of those harder. The firms know this and hire people who either have no competing obligations or who are willing to deprioritize them.
Compensation does not fully offset the hours. An analyst might earn $100,000 to $150,000 in base salary plus a bonus, which sounds high until you calculate the hourly rate during a 100-hour week. You are earning less per hour than a plumber or electrician, but with less control over your schedule and more stress.
The Technical Skills You Have to Master Quickly
Investment banking requires you to learn financial modeling, valuation, deal structuring, and accounting at a level most people never reach. A financial model is a spreadsheet that projects a company's cash flows, calculates its value, and shows how different scenarios change that value. Building one correctly takes precision—a single formula error can make a $500 million company look like a $400 million company, which changes the entire deal. You are expected to spot these errors in other people's work and in your own.
Valuation methods—discounted cash flow, comparable companies, precedent transactions—are not intuitive. You have to understand not just how to calculate them but when to use each one, what assumptions matter most, and how to defend your numbers to skeptical clients and senior bankers. This takes months of repetition to internalize, and you are learning while under time pressure and sleep deprivation.
Deal structuring is the art of arranging the financial terms so the deal works for both the buyer and seller, the lenders and equity investors, and the firm's fee. It requires you to hold multiple constraints in your head at once and find solutions that satisfy all of them. This is harder to teach than modeling because it depends on judgment and experience. You learn it by watching senior bankers, asking questions, and making mistakes on smaller deals before you touch bigger ones.
The Revenue Pressure and Client Relationships
Your technical skills matter, but they are not enough. Investment banks make money by charging fees on deals, and those fees come from clients. A junior banker does not directly bring in clients, but you are expected to support the senior bankers and partners who do. This means you attend client dinners, you help prepare pitches, you follow up on leads, and you build relationships with people who might hire the firm years later. This part of the job is harder to measure and harder to control than technical work.
The pressure to contribute to revenue grows as you advance. After two or three years, you move from analyst to associate, and the expectation shifts. You are still doing technical work, but you are also expected to help identify new business opportunities, maintain relationships with existing clients, and eventually bring in your own deals. People who are good at the technical work but bad at relationships often hit a ceiling. People who are good at relationships but weak on technical work get pushed out. You have to be competent at both.
Why People Leave After Two Years
The analyst contract at most banks is two years. Many people do not renew. The reasons are straightforward: the hours are unsustainable if you want a life outside work, the pressure is relentless, and the work itself, while interesting, is repetitive. You build the same models, value the same types of companies, and attend the same types of meetings. The learning curve flattens after the first year, so the difficulty stops feeling like growth and starts feeling like grind.
Burnout is real and common. People report depression, anxiety, and physical health problems from the sustained stress and sleep deprivation. Some firms have made efforts to limit hours—no emails after 9 p.m., no work on weekends—but these policies are often honored in the breach. The culture of the firm and the deal cycle matter more than the official policy.
The people who stay are usually those who find the work intellectually engaging enough to justify the cost, who have personal circumstances that allow for the schedule, or who are willing to endure it for a few years to build credentials and connections for the next job. Many use banking as a stepping stone to private equity, hedge funds, or corporate finance roles that pay similarly but with better hours.
Variation by Bank, Group, and Deal Cycle
Not all investment banking jobs are equally hard. The bulge bracket banks—Goldman Sachs, Morgan Stanley, JPMorgan Chase, Bank of America Merrill Lynch—have the most intense cultures and the longest hours. Smaller boutique banks sometimes have better hours but less prestige and fewer resources. Within a bank, some groups are busier than others. Mergers and acquisitions and leveraged finance are typically the most demanding. Capital markets and advisory groups can be less intense.
Deal cycles also matter. If you join during a slow period, your first six months might be manageable. Then a wave of deals hits and the hours spike. The opposite can happen—you join during a busy period, survive it, and then experience a slower stretch where you actually have time to think. The randomness makes it hard to predict what you are signing up for.
What Makes It Easier or Harder
Investment banking is harder if you are detail-oriented and anxious—you will worry about every number and every client interaction. It is easier if you are comfortable with ambiguity and can let go of things you cannot control. It is harder if you need consistent sleep and predictable schedules. It is easier if you can function on five hours of sleep and adapt to last-minute changes. It is harder if you have family obligations or health issues. It is easier if you have a support system that can absorb the disruption.
It is also harder if you are not interested in finance. If you are doing it purely for the money or the resume line, the difficulty will feel pointless. If you find the work interesting—if you enjoy building models, understanding how deals work, and solving financial puzzles—the difficulty feels more like a challenge than a burden. That does not make the hours easier, but it makes them more bearable.
Frequently Asked Questions
Do investment bankers really work 100-hour weeks?
During active deal cycles, yes. This is not an exaggeration or a badge of honor—it is a structural reality of the job. Slower periods might be 60 to 70 hours per week. Averaged across the year, most analysts work 80+ hours per week. The hours are heaviest in the first two years.
Is investment banking harder than other finance jobs?
It is harder in terms of hours and intensity, but not necessarily in terms of technical difficulty. Quantitative research and trading require deeper math skills. Corporate finance requires broader business knowledge. Investment banking is hard because of the combination of technical work, time pressure, and unpredictable schedule, not because the individual tasks are uniquely complex.
Can you have a normal life while working in investment banking?
Not during your first two years as an analyst. You can have a life outside work, but it will be limited. Relationships, hobbies, and health take a back seat. After you move to associate level and have more control over your schedule, it becomes more possible, but it depends on the deal cycle and your group.
What percentage of analysts quit before their contract ends?
The exact number varies by bank and year, but roughly 10 to 20 percent of analysts leave before completing their two-year contract. Many more complete the contract but do not stay for a third year. The firms expect this turnover and plan for it.
Does the pay make the difficulty worth it?
That depends on your goals and what you value. The pay is high relative to other entry-level jobs, but the hourly rate is often lower than skilled trades. If you are using banking as a credential to move into private equity or another high-paying field, it might be worth it. If you are doing it purely for the money, there are easier ways to earn similar amounts.
