Money performs several crucial functions in an economy:

1. Medium of Exchange: Money is widely accepted as payment for goods and services. This eliminates the need for barter, making transactions more efficient. Without money, bartering would be cumbersome and limit economic activity.
2. Store of Value: Money allows people to save purchasing power over time. While inflation can erode its value, money generally retains its value better than most goods and services. This encourages saving and investment.
3. Unit of Account: Money provides a common measure of value for goods and services. This allows for easy comparison of prices and the calculation of economic activity (e.g., GDP). A consistent unit of account simplifies accounting and financial decision-making.
4. Standard of Deferred Payment: Money facilitates borrowing and lending. Loans are typically repaid in monetary terms, allowing for long-term investments and economic growth. Without a reliable unit of account, lending and borrowing would be difficult to manage.

Each of these functions is essential for a well-functioning economy. They facilitate trade, encourage saving and investment, and provide a framework for economic planning.
