What encompasses all decisions and activities regarding an individual's or family's money?

Personal finance is the term that comprehensively encompasses all decisions and activities regarding an individual's or family's money. It involves budgeting, saving, investing, and planning for future financial needs, such as retirement or education. Personal finance encompasses understanding income, expenses, and managing debt, as well as making informed choices about financial products and services.

While economics touches on broader concepts like the production, distribution, and consumption of goods and services in society, it does not specifically focus on individual or family financial decisions. Accounting is primarily concerned with the systematic recording, reporting, and analysis of financial transactions but does not directly relate to personal financial management as a whole. An investment strategy, on the other hand, specifically relates to the plans or methods for growing one's investments and is just one aspect of personal finance, rather than covering the entirety of individual financial decision-making.
