How does the AFN equation relate to a firm's projected increase in assets and its spontaneous increases in liabilities?

The AFN equation relates a firm's projected increase in assets to its spontaneous increases in liabilities by calculating the additional funds needed (AFN) to support growth. As a firm increases sales, it requires more assets, which can be partially financed through spontaneous increases in liabilities such as accounts payable and accrued wages. The AFN equation accounts for these spontaneous increases and any additional retained earnings to determine the total external financing required.

The AFN equation is structured to show how much external capital a firm needs to support its planned growth. When a firm's sales increase, it typically needs to increase its assets to maintain operations, which is reflected in the AFN calculation. Spontaneous increases in liabilities, such as accounts payable and accrued wages, arise from normal business operations and help reduce the need for external financing. The AFN equation combines the projected increase in assets with these spontaneous increases in liabilities and any addition to retained earnings to determine the total additional funds needed for growth.
