Finance is a wide term encompassing many things regarding the study, development, management, generation, and distribution of funds. It is the scientific management of the exchange of monetary values. Finance has various other names such as economics, accountancy, economics, investment banking, financial analysis, management science, and the like. The discipline of finance is also called mathematics of business because it studies the interactions of people, institutions, and governments that affect the supply, price, allocation, accessibility, and risk of funds.

Finance theory is concerned with the economic processes by which value is created and prices are determined. It also studies the relationships between economic quantities and prices. The scope of the discipline of economics is quite broad and is further divided into micro-economics, macro-economics, and social economics. Micro-economics is the study of how people in firms contribute to the production of goods and services, while macro-economics considers large issues affecting the total economy.

Finance is essential for all types of organizations from small businesses to large corporations. It is a part of the management of capital assets and funds; it involves the collection, storage, allocation, monitoring, and allocation of funds. The modern function of finance is increasingly focused on financial reporting, budgeting, financial risk management, credit risk management, insurance products, and asset protection. Modern finance theories also include notions such as the theory of asset allocation, portfolio balance, the capital budget, financial markets, international finance, the real estate market, and the role of finance in education.

The major components of modern economics and finance are money, credit, activities, and institutions. Money is the most important part of any economy, and it is used to make loans to enterprises, purchase items, and make purchases with cash. Credit is an open source of funds that can be converted to money when needed. Many modern financial institutions such as banks, enterprises, and credit unions use money to make loans to other enterprises and to facilitate financial transactions.

The role of finance in the financial systems of industrialized nations is very vast. It covers all the aspects of business activities. It includes savings, investment, banking, commercial activities, government budgets, and direct foreign investment. Large-scale banking is the mainstay of finance in industrialized nations, although small-scale and foreign bank lending has become more widespread in recent years.

The main functions of finance in a country are to track, manage, and control the resources of the economy. Governments allot funds to the various economic sectors and distribute them to specific purposes. In fact, governments often allocate funds through direct investment programs in line with the anticipated needs and purposes of the sector. For example, a defense program may require funding for equipment, facilities, and training. Accounting methods are applied to identify the sources of these funds so that appropriate quantities can be allocated.

Another function of finance is to regulate investment and the financial aspects of businesses. Finance decides whether to make a particular investment or not. Through regulation, it prevents the absorption of surplus funds into the economy. Regulations also keep insurance companies and banks from taking excessive risks that would result in losses to the economy.

Finance also encompasses the financial management of the public budget. It is the process of managing the fiscal policy of an enterprise. In fact, the principles of economics, especially the concept of supply and demand, are intimately connected with the study of finance. Proper management of the budget means that sufficient public resources are available to satisfy the requirements of the economy. There are several subfunctions of finance that contribute to the overall efficiency of the economic system.
