Investment banking is the business of helping companies and governments raise money and manage large financial deals
Investment banks sit between organizations that need capital and the investors who have money to put somewhere. When a company wants to go public, sell itself, or borrow billions, it hires an investment bank to structure the deal, find buyers, and negotiate terms. When a government needs to borrow, an investment bank underwrites the bonds. The bank makes money through fees — a percentage of the deal size, not from owning the money itself.
This is different from retail banking, where you deposit your paycheck and get a mortgage. Investment banks do not take deposits or lend to individuals. They work with large sums, long timelines, and complex contracts. A single deal can take months and involve dozens of people across multiple offices.
Key Takeaways
- Investment banks earn fees by helping companies raise money through stock offerings, bond sales, and mergers — not by lending their own capital.
- The main divisions are corporate finance (mergers and acquisitions), capital markets (underwriting stocks and bonds), and sales and trading (buying and selling securities for clients).
- Entry-level jobs like analyst and associate require strong math skills, attention to detail, and the ability to work long hours on financial models and pitch books.
- Most investment bankers work toward either partnership at the bank or a move to a corporate finance role at a large company.
The three main divisions and what each one does
Corporate finance (also called mergers and acquisitions, or M&A) advises companies on buying other companies, selling themselves, or restructuring. A team might spend six months helping Company A understand whether to acquire Company B, modeling what the deal would cost, finding financing, and negotiating with Company B's advisors. The bank earns a fee based on the deal size — typically 0.5 to 1 percent for a large acquisition.
Capital markets helps companies and governments issue new securities — stocks or bonds — to raise money. When a company decides to go public, the capital markets team underwrites the offering, meaning it buys the shares from the company at a set price and sells them to investors at a higher price. The spread is the bank's profit. This division also manages existing securities and advises on pricing and timing.
Sales and trading buys and sells securities — stocks, bonds, derivatives — on behalf of the bank's clients, which are usually large institutions like pension funds and hedge funds. Traders sit at desks watching markets in real time, executing trades and managing risk. Salespeople maintain relationships with clients and pitch them on trading ideas. This division makes money from the bid-ask spread (the difference between what they buy and sell for) and from commissions.
The career ladder and what each level does
Entry-level positions are analyst roles, typically filled by college graduates. Analysts build financial models in Excel, create pitch books (presentations showing deal scenarios), gather market data, and handle administrative work. The hours are long — 60 to 80 hours per week is common during active deals — and the work is repetitive, but it teaches the fundamentals of how deals are structured.
After two to four years, an analyst moves up to associate. Associates manage analysts, take on more client contact, and begin to develop their own deal ideas. They still model and present, but they also start to lead smaller pieces of transactions. An associate might run the financial analysis for a specific part of a merger or lead the pitch to a client on a particular strategy.
Vice president (VP) is the next step, usually reached after four to six years as an associate. VPs manage associates and analysts, own client relationships, and lead deal teams. They spend more time on strategy and less on spreadsheets, though they still review all the numbers. A VP might be the main point of contact for a client and responsible for bringing in new business.
Director and managing director (MD) are senior roles focused almost entirely on client relationships, business development, and firm strategy. MDs are often partners or near-partners in the bank and earn a share of profits. These roles typically require 15 to 20 years of experience and a track record of closing major deals.
What the day-to-day work actually looks like
Most of your time is spent in Excel or PowerPoint. You build models that show what a deal would cost, what the returns would be, and how sensitive those returns are to changes in assumptions. You create pitch books — 50 to 100 slide presentations that walk a client through a strategy, show comparable deals, and recommend a course of action. You gather data on comparable companies, recent transactions, and market conditions. You attend meetings with clients, internal teams, and lawyers.
The rhythm depends on the division. In M&A, you work intensely on a few deals at a time, with long stretches of modeling and presentation-building, then a sprint when the deal closes. In capital markets, you work on multiple offerings simultaneously and respond to market conditions in real time. In sales and trading, your day is driven by market hours — you are at your desk when markets are open and leave when they close.
The hours are not evenly distributed. During slow periods, you might leave at 7 p.m. During deal closings or market stress, you might work through the night. Many analysts and associates report working 80 to 100 hours per week during active deals, with little advance notice.
Skills and background that matter for getting hired
Most investment banks hire analysts directly from college, usually through campus recruiting. They look for strong grades in math, economics, or finance, but also for demonstrated interest in business — internships, case competitions, or finance clubs. They want people who can handle pressure, work in teams, and communicate clearly in writing and presentations.
Excel and financial modeling are taught on the job, but you should understand basic accounting and be comfortable with numbers. You do not need to know how to code, though some banks now hire people with programming skills for technology and data roles.
For lateral hires (people moving from other jobs), banks look for deal experience, client relationships, or a track record in a related field like corporate finance, private equity, or accounting. An MBA is not required to start as an analyst but is common for people entering at the associate level from non-finance backgrounds.
Why people leave investment banking and where they go
The hours and stress burn people out. Many analysts and associates leave after two to four years, even if they are on track to be promoted. The work is intellectually demanding but often repetitive — you are building variations of the same model for the hundredth time. The pay is high relative to other entry-level jobs, but the hourly rate is often lower than it appears when you divide salary by actual hours worked.
Common next moves are to private equity (where you use deal experience to invest in companies), corporate finance (where you work on deals from the company side instead of the advisory side), or business school. Some people move to hedge funds, real estate, or venture capital. A smaller number stay in banking and move up the ladder toward partnership.
The exit opportunities are one reason people take investment banking jobs despite the hours — the experience is valued across finance, and the network you build opens doors. But most people do not stay for a full career.
Compensation and what affects your pay
Analyst compensation varies by bank and location. At major banks in New York, an analyst might earn $85,000 to $110,000 in base salary, plus a bonus that ranges from $20,000 to $60,000 depending on the year and the bank's performance. Associates earn more — typically $150,000 to $200,000 base plus $50,000 to $150,000 bonus. VPs earn $250,000 to $500,000 or more.
The bonus is the larger part of compensation and fluctuates with the bank's revenue. In a strong year, bonuses are generous. In a weak year, they can be cut sharply or eliminated. Your personal bonus also depends on your performance, the performance of your team, and the performance of your division.
Banks outside major financial centers (London, Hong Kong, San Francisco) typically pay less, sometimes 20 to 30 percent lower. Smaller banks and boutique firms also pay less than the largest global banks, though the hours may be more reasonable.
Frequently Asked Questions
Do I need an MBA to work in investment banking?
No. Most banks hire analysts directly from college with just a bachelor's degree. An MBA is more common for people entering at the associate level or higher, or for people coming from non-finance backgrounds. Some people get an MBA after working as an analyst for a few years, often paid for by the bank.
What is the difference between investment banking and commercial banking?
Commercial banks lend money to businesses and individuals, take deposits, and manage day-to-day financial services. Investment banks advise on deals and capital raising but do not lend their own money or take deposits. Some large banks have both divisions, but they operate separately.
How much travel is involved in investment banking?
It depends on the role and the deal. M&A bankers often travel to meet clients and visit companies being acquired. Capital markets and trading roles involve less travel. During deal closings, you might travel for a week or two. Most travel is domestic, but international deals require trips abroad.
Can you work in investment banking part-time or remotely?
Not typically. Investment banking requires long hours and in-person collaboration, especially at the analyst and associate levels. Some banks have experimented with flexible arrangements for senior roles, but entry-level positions are expected to be full-time and office-based.
What happens if a deal falls through after months of work?
You move to the next deal. Deals do fall apart — clients change their minds, financing falls through, or regulatory approval is denied. The bank still earns a fee in some cases, but not always. Either way, the team that worked on it shifts to other projects. It is frustrating but normal.
