A chief financial officer (CFO) is the senior executive responsible for all of a company’s financial activities, including cash flow, financial planning, accounting and reporting, and tax matters. The CFO also analyzes where the business is financially strong or weak and proposes corrective action. In most companies the CFO holds the highest finance position and usually ranks third among executives, behind the chief executive officer (CEO) and, where the role exists, the chief operating officer (COO).

What Does a CFO Actually Do?

The CFO runs the finance function and acts as a strategic partner to the CEO, combining accurate records of past results with planning for the company’s future. Typical responsibilities include:

• Financial planning and forecasting: building budgets, projecting revenue and expenses, and modeling how decisions affect future results.
• Cash flow management: making sure the company has the liquidity to pay suppliers, employees and lenders on time.
• Capital structure and funding: deciding how much the business relies on debt versus equity, and raising money for new initiatives.
• Investment decisions: reviewing proposed projects, acquisitions and major purchases using cost-benefit analysis.
• Financial reporting: making sure financial statements are accurate, complete and delivered on time.
• Compliance and controls: keeping the company within accounting standards, securities rules and tax law, and maintaining internal controls against error and fraud.
• Process and quality oversight: improving how the finance and accounting teams work.

Where the CFO Fits in a Company

The CFO is a member of the C-suite, the group of top executives that typically includes the CEO, the COO and the chief information officer (CIO). The CFO generally reports to the CEO and often works closely with the board of directors and its audit committee.

Within finance, the CFO is the final decision-maker. Accounting, treasury, tax and financial planning and analysis teams report up to the CFO, usually through a controller and a treasurer in larger organizations. At the strategic level, the CFO sets the financial limits other executives work within.

Example: A CFO Reviewing a Marketing Proposal

Hypothetical example. A consumer goods company’s marketing team proposes a national campaign with an upfront cost of $2 million. Before the CEO approves it, the CFO’s team would typically:

1. Check whether the budget can absorb the cost, or whether money has to be moved from another project or raised externally.
2. Estimate the added sales and margin the campaign is expected to produce, and over what period.
3. Discount those expected cash flows to compare them with the upfront cost, for example by calculating net present value (NPV) or the internal rate of return.
4. Test what happens if sales come in below plan, and how that would affect cash flow in the following quarters.

If the projected return clears the company’s required rate and cash reserves stay adequate, the CFO may support the campaign. If not, they may recommend a smaller rollout or a delay. The CFO does not design the campaign. Their contribution is deciding whether the company can fund it and whether the expected payoff justifies the cost.

Regulations and Compliance for CFOs

In the United States, public company CFOs must prepare financial statements under generally accepted accounting principles (GAAP), the standards the Securities and Exchange Commission (SEC) recognizes for financial reporting. The Sarbanes-Oxley Act of 2002, passed after the accounting scandals at Enron and WorldCom, made this responsibility personal. Under the act, the CEO and CFO must certify that periodic reports filed with the SEC are accurate and that the company maintains effective internal controls. Knowingly certifying false reports can bring criminal penalties.

CFOs also work in the public sector, where governments appoint them to oversee taxation, manage public funds and set financial policy. At the federal level, the Chief Financial Officers Act of 1990 created CFO positions across major agencies. The supporting staff is often called the Office of the Chief Financial Officer (OCFO).

CFO vs. Related Roles

Several roles are often confused with the CFO:

• Accountant: Accountants handle bookkeeping, record transactions and prepare tax filings. Many CFOs trained as accountants, but the role focuses on planning, forecasting and strategy rather than day-to-day bookkeeping.
• Controller: The controller runs the accounting function, closes the books and produces the financial statements, and usually reports to the CFO.
• Treasurer: The treasurer manages cash, banking relationships, investments and debt, and also commonly reports to the CFO.
• CEO: The CEO is responsible for the entire company and makes the final call on overall strategy. The CFO’s authority is concentrated on finance.
• Finance director: In many companies, particularly in the UK, this is the title for the top finance executive, effectively the same job as a CFO. Elsewhere, a finance director is a level below the CFO.

How to Become a CFO

The CFO position generally goes to experienced professionals with a long track record in finance. Many hold advanced degrees, such as a master’s in finance, an MBA or a graduate degree in economics, along with professional credentials such as the Chartered Financial Analyst (CFA) designation. Common career paths run through accounting, investment banking, corporate finance or financial analysis, often with time as a controller, treasurer or divisional finance head before reaching the top job.

For finance professionals, the CFO role is among the most prestigious and highest-paid positions in a company. Pay varies widely with company size, industry and location.

Limitations of the Role

A CFO’s influence is real but bounded. The CEO and board approve major strategic decisions, so a CFO can recommend against a project and still be overruled. Forecasts are only as reliable as their assumptions, and a well-built plan can still miss when markets or demand shift. Smaller businesses may have no full-time CFO, with duties split among an owner, an outside accountant and a bookkeeper, so no single person is responsible for both reporting and long-range planning.

The Bottom Line

Finance professionals weighing a path to the top job, and anyone trying to understand how companies make money decisions, can treat the CFO as the executive who sets the financial limits for everyone else. The role usually goes to people with deep finance experience and advanced credentials. Its authority still has limits, since the CEO and board can overrule a CFO's recommendation and forecasts depend on their assumptions.
