Investment bankers help companies and governments raise money and make big financial deals happen

An investment banker is not a person who manages your savings account — that is a retail banker. Instead, investment bankers work on large transactions: when a company wants to sell shares to the public for the first time, when one company wants to buy another, or when a government needs to borrow billions of dollars. The investment banker's job is to figure out what the deal is worth, find the buyers or sellers, and guide both sides through the paperwork and negotiations.

Investment banking is a specialized career path inside larger banks. A bank like JPMorgan Chase or Bank of America has a retail division (where you open a checking account) and an investment banking division (where teams work on corporate deals). These divisions rarely interact. If you are considering this career, you should know that the work is project-based, the hours are long during active deals, and the pay structure is different from other banking jobs — much of your income comes from bonuses tied to the deals you close.

Key Takeaways

  • Investment bankers advise companies on major financial decisions like going public, being acquired, or raising capital, and they earn money when those deals close.
  • The job has three main roles: analysts (entry-level, do research and build financial models), associates (manage client relationships and oversee deals), and managing directors (bring in clients and make final decisions).
  • Investment banking is different from wealth management, trading, and retail banking — each is a separate career path with different daily work and pay structures.
  • The typical path into investment banking is a four-year degree in finance, economics, or accounting, followed by an internship during college, then a full-time analyst role after graduation.

The three main roles and what each person does

Investment banking teams are organized by rank, and each level has a different job. At the bottom is the analyst — usually someone fresh out of college. Analysts spend most of their time building financial models (spreadsheets that show what a deal might be worth), gathering information about companies in the same industry, and writing pitch books (documents that explain why a client should hire this bank for their deal). An analyst might work 60 to 80 hours a week, especially when a deal is active.

Above the analyst is the associate. Associates have usually worked as analysts for two to three years, or they came in with an MBA. An associate manages the day-to-day relationship with the client, makes sure the analyst's work is correct, and coordinates with lawyers and accountants. Associates also start to pitch new business — they might call a company's CFO (chief financial officer) to suggest a deal idea. Associates work long hours too, but they have more control over their schedule than analysts do.

At the top are managing directors and partners. These people bring in the clients, make the final decisions on deals, and mentor the junior staff. A managing director might spend half their time in client meetings and half their time recruiting new business. They are the ones who decide whether the bank will take on a deal, and they sign off on the final numbers.

What actually happens during a deal

Let's say a mid-sized manufacturing company wants to be bought by a larger competitor. The company's CEO calls an investment bank and asks for help. The bank sends a team — usually an associate and two or three analysts — to meet with the company's leadership. The bank explains what it can do: find potential buyers, value the company, negotiate terms, and manage the legal process.

If the company hires the bank, the analysts start building a financial model. They gather five years of the company's financial statements, look at what similar companies sold for, and create a range of possible prices. Meanwhile, the associate prepares a list of potential buyers — other manufacturers, private equity firms, or larger competitors. The bank reaches out to these buyers confidentially (using a fake name for the company at first, to keep the sale secret).

When a buyer shows serious interest, the bank arranges meetings between the buyer and the seller. The bank's associate sits in on these meetings and helps negotiate. If both sides agree on a price, the bank's work is mostly done — lawyers take over the paperwork. But the bank stays involved to make sure the deal closes. Once it does, the bank gets paid a fee, usually a percentage of the deal's value. That fee is split among the team members as salary and bonus.

How investment banking differs from other banking jobs

Investment banking is often confused with other finance careers because they all happen inside banks. But they are very different jobs. Wealth management advisors help rich individuals invest their money — they manage portfolios and give information on stocks and bonds. Traders buy and sell securities (stocks and bonds) for the bank's own account, trying to make money on price changes. Retail bankers work with regular customers on mortgages, savings accounts, and small business loans.

Investment bankers do none of these things. They do not manage money, they do not trade, and they do not work with retail customers. They advise on big corporate transactions. The pay is also different: investment bankers earn a base salary plus a large bonus (sometimes larger than the base salary) when deals close. Retail bankers earn a salary plus a smaller bonus. Traders earn a salary plus a commission based on their trading profits.

The hours are also different. Investment bankers work long hours during deal season (usually spring and fall), but slower periods exist. Traders work intense hours every trading day. Retail bankers have more predictable schedules. If you are considering investment banking, you should know that you will have weeks where you work 80 to 100 hours, and you will miss weekends and evenings with family.

How to start an investment banking career

Most investment banks hire analysts straight out of college, and most of those hires come from a small group of schools and a smaller group of majors. The typical path is: major in finance, economics, accounting, or mathematics; do an internship at an investment bank during your junior or senior year; then explore for the full-time analyst program after graduation.

The internship is critical. Banks use summer internships to test whether you can do the work and whether you fit the culture. If you perform well as an intern, the bank will often offer you a full-time job before you graduate. If you do not intern, you can still get hired, but you will be competing against hundreds of candidates who did.

To land an internship, you need to network. This means reaching out to alumni from your school who work at the bank, attending recruiting events, and explore through the bank's website. You should also be able to talk about why you want the job — not "I want to make a lot of money," but "I want to understand how large companies make strategic decisions" or "I want to learn financial modeling and valuation." Banks want people who are genuinely interested in the work.

What the day-to-day work actually looks like

If you are an analyst, your day might start at 8 a.m. with a meeting where the associate explains what needs to be done. You spend the next six hours building a spreadsheet that values a company using three different methods. At 2 p.m., the associate asks you to change one of the assumptions in the model — the client thinks the company's growth rate will be lower. You rebuild the model. At 5 p.m., the associate reviews your work, finds an error, and asks you to fix it. You fix it. At 7 p.m., you send the updated model to the associate. At 9 p.m., the associate sends you feedback and asks for another version. You work until midnight.

This is not every day, but it is common during active deals. On slower days, you might spend time researching companies, reading financial news, or learning new Excel techniques. You might also attend client meetings, though as an analyst you usually sit quietly and take notes.

If you are an associate, your day is different. You might start with a call to a potential client, pitching a deal idea. Then you review the analyst's work on an active deal. Then you have lunch with a client to discuss their timeline. Then you spend two hours in a meeting with lawyers and accountants to work out the details of a deal. Then you review the analyst's revised model and send feedback. You leave the office at 8 p.m., but you check email from home until 11 p.m.

Why people choose investment banking and why they leave

People are drawn to investment banking for several reasons. The pay is high — analysts earn $100,000 to $150,000 in base salary plus bonus, and associates earn significantly more. The work is intellectually challenging — you learn financial analysis, negotiation, and how large companies operate. You also build a network of contacts that can help you later in your career, whether you stay in banking or move to another field.

But many people leave investment banking after a few years. The hours are exhausting. The work is repetitive — you build similar models and pitch similar deals. You miss time with family and friends. And after a few years, you realize that the bank makes far more money from your work than you do, which can feel unfair. Many analysts leave after two or three years to go to business school, move to private equity (a related field with slightly better hours), or switch to a completely different career.

Frequently Asked Questions

Do investment bankers actually work 100-hour weeks?

During active deals, yes — 80 to 100 hours per week is common for analysts and associates. But this is not every week. Slower periods exist when the hours drop to 50 to 60 per week. The unpredictability is part of the challenge: you cannot plan your personal life around a fixed schedule.

What degree do I need to become an investment banker?

Most banks hire analysts with a four-year degree in finance, economics, accounting, or mathematics. Some hire physics or engineering majors if they show strong quantitative skills. You do not need an MBA to start as an analyst, but many people get one after working for two or three years.

How much do investment bankers make?

Analysts earn roughly $100,000 to $150,000 in base salary plus a bonus that can equal or exceed the base. Associates earn $150,000 to $250,000 in base plus bonus. Managing directors earn significantly more, but the exact amount varies by bank, deal flow, and individual performance.

Is investment banking the same as being a financial advisor?

No. Financial advisors help individuals invest their personal money. Investment bankers advise companies on major transactions like mergers and going public. The skills overlap slightly, but the clients, the work, and the pay structure are completely different.

Can I move from investment banking to another job later?

Yes. Investment banking experience is valued in many fields: private equity, corporate finance, management consulting, and venture capital all hire people with investment banking backgrounds. The skills you learn — financial modeling, valuation, negotiation — transfer to these roles.
