Overview & Strategic Context
The Additional Funds Needed (AFN) Calculator is a financial forecasting tool used by businesses to determine the amount of external financing required to support a projected increase in sales. When a company grows, it typically needs more assets (inventory, equipment) to support that growth. Some of this funding comes naturally from increased liabilities (like accounts payable) and retained earnings, but often a gap remains. The AFN equation identifies this gap, telling you exactly how much money you need to raise through loans or equity.
Methodology & Formula
The AFN formula is:
AFN = Required Asset Increase - Spontaneous Liability Increase - Increase in Retained Earnings
Mathematically: `AFN = (A*/S0)ΔS - (L*/S0)ΔS - (M * S1 * RR)`
Where ΔS is the change in sales, A* is assets tied to sales, L* is spontaneous liabilities, M is profit margin, S1 is projected sales, and RR is retention ratio.
