The core job: financial modeling, pitch books, and due diligence

An investment banking analyst spends most of their time building financial models in Excel, creating presentation decks called pitch books, and gathering information about companies for deals. You are not meeting with clients or closing transactions—that is the managing director's job. You are the person who does the math, pulls the data, and makes sure the numbers in the pitch are defensible.

On a typical day you might spend four hours building a model that shows what a company will be worth under different scenarios, two hours updating a slide deck for a client meeting, and two hours digging through SEC filings or industry reports to find comparable companies. The work is repetitive by design: the same types of models, the same slide templates, the same data sources, used over and over on different deals.

Most analysts work in one of three groups: mergers and acquisitions (M&A), where you model what happens when one company buys another; capital markets, where you help companies raise money by selling stock or bonds; or industry-specific groups like technology or healthcare, where you focus on deals in that sector.

Key Takeaways

  • Investment banking analysts spend most of their time building Excel models, creating pitch decks, and researching companies—not meeting clients or negotiating deals.
  • The job requires you to work long hours (60 to 80 per week is standard) and be on call during deal periods, when you may work through the night.
  • You report to associates and managing directors, and your work gets reviewed and revised multiple times before it reaches a client.
  • The role is an entry point to finance careers: some analysts move into private equity or hedge funds, others leave banking after two or three years for corporate jobs.
  • Compensation includes a base salary (typically $80,000 to $100,000 at large banks) plus a bonus that can equal or exceed the base, depending on the bank and the year.

What the work looks like hour by hour

Financial modeling is the core skill. You build a spreadsheet that projects a company's revenue, expenses, and cash flow for five to ten years, then calculates what the company might be worth. You do this dozens of times—once for each company in a pitch, once for each scenario a client asks about, once to test what happens if interest rates change. The model is not your original idea; you follow a template and plug in new numbers. But the numbers have to be right, and the logic has to hold up if a client questions it.

Pitch books are the decks you show to potential clients or to the company being acquired. They contain the financial models you built, comparisons to similar deals, and the bank's recommendation on price or strategy. You do not write the narrative or set the strategy—the senior bankers do that. You make sure the slides are formatted correctly, the numbers match across all the slides, and the charts are accurate. This work is tedious and detail-oriented. A single typo or a formula error can force you to redo slides at 2 a.m.

Due diligence means researching a company before a deal moves forward. You read through years of financial statements, earnings call transcripts, and regulatory filings. You build a database of information about the company's customers, competitors, and market position. You may call industry experts or former employees to understand the business better. This information feeds into the models and the pitch.

The schedule and the pressure

Investment banking analysts work long hours. During active deal periods—when the bank is pitching to clients or closing a transaction—you may work 70 to 80 hours per week. This includes nights and weekends. You might finish a pitch deck at midnight, get notes from the managing director at 6 a.m., and have a revised version ready by 9 a.m. for a client call. Deals move fast, and you are expected to move with them.

Outside of deal periods, the hours are lighter—maybe 50 to 60 per week—but you are still on call. A client question or a new deal can pull you back in at any time. The unpredictability is part of the job. You cannot plan your personal life around a fixed schedule.

The pressure comes from two directions: the clients expect accurate, polished work, and the senior bankers expect you to deliver it without mistakes. If a model has an error or a slide is sloppy, you hear about it immediately. There is little room for "good enough." This pressure is intentional—the bank is using the analyst role to filter for people who can handle high-stakes work under tight deadlines.

Who you work for and how the hierarchy works

As an analyst, you report to an associate, who reports to a vice president, who reports to a managing director. The managing director owns the client relationship and makes the strategic decisions. The VP manages the deal team and reviews your work. The associate is usually only two or three years ahead of you and often does similar work, just with more autonomy and higher pay.

Your work gets reviewed multiple times before it reaches a client. The associate checks it first, then the VP, then sometimes the managing director. Each person may ask for changes or ask you to rebuild a section. This is normal and expected. The bank's reputation depends on the quality of the work, so there is no such thing as "final" until the client sees it.

You also work alongside other analysts on the same deal. You may divide the work—one person builds the valuation model, another builds the comparable companies analysis, another creates the pitch slides. You coordinate through shared spreadsheets and group chats, often across time zones if the bank has offices in multiple cities.

What skills you need and how you develop them

Excel is the primary tool. You need to be fast and accurate with formulas, pivot tables, and data manipulation. Most analysts learn Excel on the job, but having some experience before you start is helpful. You also need to understand basic accounting and finance concepts: how to read an income statement, what cash flow means, how to calculate return on investment.

Attention to detail matters more than raw intelligence. The work is not conceptually difficult, but it is easy to make mistakes when you are tired and working fast. Analysts who catch their own errors before they reach a senior banker move up faster.

Communication skills are important too. You need to explain your model to someone who did not build it, answer questions about your assumptions, and incorporate feedback without getting defensive. Most of this happens in writing—emails and chat messages—so clarity matters.

You develop these skills through repetition. Your first model takes a week; your tenth takes a day. Your first pitch deck is clumsy; your fiftieth is polished. The bank expects you to get faster and better at a predictable rate. If you are not improving after six months, that is a signal that the job may not be the right fit.

The path forward: staying or leaving after two or three years

Most analysts stay for two to three years, then move on. Some move up within the bank—from analyst to associate—but this is less common than it used to be. More often, analysts use the role as a credential to move into private equity, hedge funds, or corporate finance jobs at large companies. The skills and the resume credential open doors.

Some analysts leave banking because the hours and the pressure burn them out. The job is designed to be intense, and it is not for everyone. If you hate Excel or you need predictable evenings and weekends, you will know within the first year.

Others stay longer because they like the work, the people, or the path to higher pay. An associate at a large bank makes $150,000 to $200,000 base plus a significant bonus. A VP makes $300,000 to $500,000 or more. The money is real, and it compounds if you stay.

Pay, bonuses, and what the total package looks like

Base salary for an analyst at a large investment bank ranges from $80,000 to $100,000, depending on the bank and the city. Smaller banks or regional firms pay less. The bonus is where the real money is. In a good year, your bonus can equal your base salary or exceed it. In a bad year—when the bank has few deals or the market is slow—the bonus can be small or zero.

Bonuses are not may provide and vary year to year. They depend on the bank's profitability, the performance of your group, and your individual performance. A managing director decides the bonus pool for the group, then divides it among the analysts based on who worked the most hours, who made the fewest mistakes, and who the senior bankers think has the most potential.

Total first-year compensation at a top-tier bank might be $130,000 to $150,000 if the bonus is strong. At a smaller bank, it might be $90,000 to $110,000. After two or three years as an analyst, if you move to an associate role, the base jumps to $150,000 and the bonus potential increases significantly.

Frequently Asked Questions

Do you actually talk to clients as an analyst?

Rarely. You might sit in on a client call and listen, but you do not lead the conversation or present your work directly. The managing director or VP presents the pitch and answers questions. You are in the room to take notes and to be ready if the client asks a detailed question about the model that the senior banker cannot answer on the spot.

What happens if you make a mistake in a model?

It depends on when the mistake is caught. If you catch it before the senior banker reviews it, you fix it and move on. If the senior banker catches it, you fix it and get feedback on how to avoid the same mistake next time. If a client catches it, it is more serious—the bank's credibility is damaged—but the analyst is not blamed alone. The whole team shares responsibility for quality control.

Is the job worth the hours?

That depends on your priorities. If you want to build a finance career, the credential and the skills are valuable. If you want to make good money quickly, the pay is solid. If you want work-life balance, this is not the job. Most analysts who stay past two years say the experience was worth it; most who leave say they needed a break.

Can you move into other finance jobs from here?

Yes. Investment banking is a common entry point to private equity, hedge funds, corporate finance, and venture capital. The modeling skills and the deal experience transfer directly. Some analysts also move into consulting or corporate strategy roles. The credential opens doors because employers know you can handle complex work under pressure.

What if you are not good at Excel when you start?

You will learn. Most analysts come in with basic Excel skills and develop advanced skills on the job. The bank expects this. If you are willing to stay late and practice, you will get better. If you avoid the learning curve or refuse to put in the effort, you will struggle.
