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

An investment banker is someone who works at a bank to help organizations buy and sell other organizations, raise money by issuing stock or bonds, or restructure their finances. They are not the same as the banker at your local branch who handles checking accounts. Investment bankers work with large sums of money and complex transactions that can take months to complete.

The core of the job is connecting people who have money to invest with companies or governments that need that money. If a company wants to go public — meaning it wants to sell shares of itself to the public for the first time — an investment banker helps make that happen. If one company wants to buy another company, an investment banker figures out the price, structures the deal, and finds the money to pay for it.

Key Takeaways

  • Investment bankers help companies raise money through stock offerings or bond sales, and they help arrange mergers and acquisitions between large organizations.
  • The job involves research, financial modeling (building spreadsheets that show what a deal is worth), and pitching ideas to clients who may spend millions based on that work.
  • Investment bankers work long hours during active deals, often 60 to 80 hours per week, because clients expect constant availability and deals move quickly.
  • Entry-level positions require a bachelor's degree, usually in finance, economics, or accounting, and many people move into investment banking from analyst or associate roles.
  • The pay is high — base salary plus bonuses that can equal or exceed the base — but the hours and stress are significant parts of the job that candidates should understand before pursuing it.

The three main types of work investment bankers do

Mergers and acquisitions (M&A) is the largest part of most investment banking jobs. When one company wants to buy another, the investment banker advises on price, structure, and financing. They research the target company's finances, build models showing what it is worth, and help negotiate the deal. They also find the money — either from the buying company's own cash, from loans, or from investors willing to put money into the deal.

Capital raising means helping organizations get money by selling pieces of themselves or by borrowing. If a company wants to go public for the first time (called an IPO, or initial public offering), the investment banker prepares the company, prices the shares, and sells them to large investors. If a company wants to borrow money by issuing bonds, the investment banker structures the bond, rates it, and sells it to investors who want a safe place to put their money.

Advisory work is when a company hires an investment banker just to think through a big decision — whether to sell itself, whether to buy a competitor, whether to restructure its debt. The banker does research and analysis and gives recommendations, but the company may or may not act on them.

What the day-to-day work actually looks like

Most of an investment banker's time is spent building financial models — detailed spreadsheets that show what a company or deal is worth based on its finances, growth rate, and the industry it is in. These models are the foundation for every pitch and every negotiation. A banker might spend a full day updating a model after a client gives new information, or building five different versions to show what happens if the deal changes.

Bankers also spend significant time in meetings — with clients to understand what they want, with other bankers on their team to divide the work, and with lawyers and accountants who help structure the deal. They prepare presentations (called "pitch books") that show why a client should hire them or why a deal makes sense. These presentations are often 50 to 100 pages long and include charts, financial projections, and comparisons to similar deals.

Research is another major part of the job. A banker needs to understand the industry their client is in, who the competitors are, what similar deals have sold for, and what the economic outlook is. This research informs the price and structure of a deal.

The hours and intensity of the job

Investment banking is known for long hours. During an active deal, bankers regularly work 60 to 80 hours per week, and during critical periods (like the final weeks before a deal closes), they may work even more. This is not a job where you leave at 5 p.m. most days.

The intensity comes from client expectations and deal timelines. A client may call at 9 p.m. asking for a new analysis, and the banker is expected to have it ready by morning. Deals move fast — a merger that seemed months away can suddenly need to close in weeks. Bankers are on call during these periods and must be ready to drop other work.

The hours are heaviest for junior bankers (analysts and associates) and lighter as you move up. Senior bankers spend more time managing relationships and less time building models, but they are still expected to be available when a major client needs them.

Education and how to start in investment banking

Most investment banks hire people with a bachelor's degree in finance, economics, accounting, or business. Some hire people with degrees in math, physics, or engineering if they have strong analytical skills. The degree itself matters less than showing you can think analytically and handle complex financial information.

The typical entry path is through an internship program. Investment banks hire interns during the summer between junior and senior year of college, and many of those interns are offered full-time jobs after graduation. If you do not get an internship, you can still be hired as an analyst (the entry-level full-time position) directly after college, but it is more competitive.

Some people move into investment banking from other roles — from accounting firms, from corporate finance jobs at large companies, or from other banks. These people usually start as associates rather than analysts, which is a step up.

Pay and career progression

Investment banking pays significantly more than many other jobs, but the pay structure is different from a typical salary. A first-year analyst might earn a base salary of $80,000 to $120,000 (this varies by bank and location), but the bonus can be another $50,000 to $150,000 depending on how well the bank performed and how well the individual performed. The bonus is not may provide and can be much smaller in a slow year.

As you move up — from analyst to associate to vice president to managing director — the base salary increases and the bonus potential increases much more. A managing director at a major bank can earn several million dollars in a good year, but this takes 10 to 15 years to reach.

Many people do not stay in investment banking for their whole career. After 3 to 5 years, some move to corporate finance jobs (working inside a company rather than at a bank), some move to private equity (investing in companies), and some leave finance entirely. The skills are valuable in many fields, and the experience is respected.

Why companies hire investment bankers instead of doing deals themselves

A company could theoretically do a merger or raise money without hiring an investment banker. But investment bankers bring informed, relationships, and credibility that are hard to build internally. A banker knows what similar deals have sold for, knows which investors are interested in this type of deal, and knows how to structure it to minimize taxes and legal risk.

Bankers also bring objectivity. A company's own finance team may be biased toward a deal they want to do, but an outside banker can give an honest assessment of whether the price is fair. And bankers have relationships with other companies, investors, and lenders that make it easier to get a deal done quickly.

The cost is real — investment banks charge fees that can be 1% to 5% of the deal value, depending on the size and complexity. But for a large deal, having the right banker can mean the difference between a deal that works and one that falls apart.

Frequently Asked Questions

Do I need an MBA to become an investment banker?

No. Most people enter investment banking with a bachelor's degree and work their way up. Some people get an MBA later in their career to move into senior roles or to switch to a different field, but it is not required to start. The internship and early job experience matter more than an advanced degree.

What is the difference between an investment banker and a stockbroker?

A stockbroker buys and sells stocks and bonds for individual investors or small companies. An investment banker helps large organizations raise money or make major acquisitions. Stockbrokers work with many small clients; investment bankers work with a few large clients on complex, long-term deals.

Is investment banking the same as working at a commercial bank?

No. A commercial bank (like your local branch) takes deposits and makes loans to individuals and small businesses. An investment bank helps large organizations raise money and make deals. Some large banks have both divisions, but the work, clients, and culture are very different.

What happens if a deal falls through after months of work?

The banker still gets paid a fee for the work, though sometimes the fee is smaller if the deal does not close. The banker moves on to the next deal. Deals fall through for many reasons — financing falls through, the client changes their mind, or the other side walks away — and it is a normal part of the job.

Can you work in investment banking if you are not good at math?

You need to be comfortable with numbers and financial concepts, but you do not need to be a math prodigy. The spreadsheets and models are tools; understanding what they mean matters more than deriving the formulas. If you can learn financial concepts and think logically, you can learn the technical skills.
