Capital

What Is Capital?

In finance, capital generally means the money and other assets used to create more wealth. A company's capital can include cash, buildings, machinery, patents, and funds raised from shareholders or lenders. An investor's capital is the money committed to investments. The core idea is that capital is set aside or committed today in the hope of producing income or growth later.

Capital is often grouped into a few forms. Equity capital is money provided by owners in exchange for ownership stakes, while debt capital is borrowed money that must be repaid with interest. Economists also distinguish between physical capital, such as factories and equipment, and human capital, the skills and knowledge of workers.

How Capital Is Used

Businesses use capital to fund day-to-day operations, buy long-term assets, and expand. A company that raises money by issuing shares and selling bonds is building its capital base. Management then allocates that capital across projects, aiming for returns higher than the cost of the money. Investors do something similar on a personal scale by allocating their own capital across different assets.

Capital also appears in the term working capital, which describes the short-term resources available for daily operations, and in capital gains, the profit from selling an asset for more than its purchase price.

Why It Matters to Investors

Capital is the raw material of investing. Investors often look at how efficiently a company uses its capital to generate profits, and measures such as return on equity are built on this idea. Because capital can be lost as well as grown, understanding where it is committed and what risks it carries is central to evaluating any investment.

The word is also used loosely. People may speak of having "capital to invest," meaning available funds, or refer to the capital markets, where stocks and bonds are traded. Context usually makes the intended meaning clear.
