How to Use the Additional Funds Needed Calculator
The Additional Funds Needed Calculator helps financial planners and business owners determine how much external financing a company requires to support a projected increase in sales.
- Enter Current Sales — Input the baseline revenue for the current period.
- Enter Projected Sales — Input the forecasted revenue for the next period.
- Enter Sensitive Assets — Input total assets that grow proportionally with sales (e.g., receivables, inventory).
- Enter Spontaneous Liabilities — Input liabilities that increase automatically with sales (e.g., payables, accruals).
- Enter Net Profit Margin — Input net income as a percentage of sales.
- Enter Dividend Payout Ratio — Input the percentage of net income paid as dividends.
- Read Results — The Additional Funds Needed Calculator displays the AFN along with the sales growth, asset increase, liability increase, and retained earnings breakdown.
Formula & Theory — Additional Funds Needed Calculator
The Additional Funds Needed Calculator uses this core formula or rule from the standard AFN model in corporate finance:
AFN = (A*/S₀) × ΔS − (L*/S₀) × ΔS − (M × S₁ × RR)| Symbol | Meaning |
|---|---|
| A* | Sensitive assets |
| L* | Spontaneous liabilities |
| S₀ | Current sales |
| S₁ | Projected sales |
| ΔS | Change in sales (S₁ − S₀) |
| M | Net profit margin |
| RR | Retention ratio (1 − dividend payout ratio) |
A positive AFN signals a funding gap that must be filled through external sources. A negative AFN signals an internal surplus.
