Flow of Funds (FOF) is both a financial and economic tool that can be used to better understand a nation's economic health. It is essentially a financial accounting system that captures economic activity by tracking the movement of funds across different industries. By showing how different sectors of the economy interact with each other, Flow of Funds provides valuable insights into the strength and direction of an economy.

The data used in Flow of Funds is collected by the nation’s central bank and made available to the public. It typically includes information such as money supply, borrowing, lending and investments. This information then forms the basis of Flow of Funds analysis. It can be used to calculate economic indicators such as Gross Domestic Product (GDP) and can also be used to inform fiscal and monetary policy.

To create a Flow of Funds diagram, the cumulative flows received or paid by households, businesses, government, and the foreign sector are aggregated over time. Hence, the Flow of Funds diagram projects the financial functioning of the nation’s economy for a particular period. It shows sources and uses of funds and emphasizes the role of households and businesses.

The Flow of Funds supports economic management by providing a comprehensive picture of economic activity. It reveals patterns of borrowing and lending, money supply and savings, and provides an in-depth analysis of how the economy is functioning. By revealing this information, the Flow of Funds helps to inform and shape the macro-level economic policies.

In conclusion, Flow of Funds is a comprehensive approach to understanding a nation’s financial landscape. It can be used to measure economic activity and inform fiscal and monetary policy. By showing the sources and uses of funds, the Flow of Funds helps to generate a fuller understanding of the nation’s economic performance.
