Additional Funds Needed (AFN)

Additional Funds Needed (AFN) is a financial forecasting formula used to determine the amount of external financing a company must raise to support a projected increase in sales. When a company's sales grow, its assets—like inventory and accounts receivable—must also grow to support that higher level of activity. This growth requires funding. While some of this funding is generated spontaneously through increased accounts payable and retained profits, there is often a shortfall. The AFN formula calculates this exact shortfall.
Understanding your AFN is critical for strategic planning, managing cash flow, and ensuring your business has the capital it needs to achieve its growth targets without facing a liquidity crisis.
The AFN Formula Explained
The standard formula for calculating Additional Funds Needed is:
AFN = (A*/S₀) * ΔS - (L*/S₀) * ΔS - M * S₁ * (1 - d)
Let's break down each component:
- (A*/S₀) * ΔS: This represents the Required Increase in Assets.
A*: Spontaneous Assets – assets that increase automatically as sales increase (e.g., inventory, accounts receivable).S₀: Current Sales – total sales revenue for the current period.ΔS: Change in Sales – the projected increase in sales dollars.
- (L*/S₀) * ΔS: This is the Spontaneous Increase in Liabilities.
L*: Spontaneous Liabilities – liabilities that increase automatically with sales (e.g., accounts payable, accrued wages). This is a source of "free" financing.
- M * S₁ * (1 – d): This calculates the Increase in Retained Earnings.
M: Net Profit Margin – the percentage of profit generated from each dollar of sales.S₁: Projected Sales – the total sales forecast for the next period (S₀ + ΔS).d: Dividend Payout Ratio – the proportion of net income paid out to shareholders. The remaining portion (1 – d) is the retention ratio, which is reinvested in the company.
How to Use the AFN Calculator
To determine your company's financing needs, simply fill in the fields with data from your financial statements and projections:
- Current Annual Sales (S₀): Your total revenue from the most recent full year.
- Projected Sales Growth Rate (%): The percentage by which you expect sales to grow next year.
- Spontaneous Assets (A*): Sum up the assets on your balance sheet that vary directly with sales. This typically includes cash needed for transactions, accounts receivable, and inventory. It excludes fixed assets like buildings and machinery in the short term.
- Spontaneous Liabilities (L*): Sum up the liabilities on your balance sheet that vary directly with sales. This includes accounts payable and accrued expenses (like wages and taxes). It excludes notes payable, long-term debt, and common stock.
- Net Profit Margin (%): Found on your income statement, calculated as (Net Income / Sales) * 100.
- Dividend Payout Ratio (%): The percentage of net income you plan to pay out as dividends. If your company does not pay dividends, enter 0.
AFN Calculation Example
Let's imagine a business, "Growth Corp," wants to forecast its financing needs for the upcoming year. Its financials are as follows:
- Current Sales (S₀): $5,000,000
- Projected Sales Growth: 25%
- Spontaneous Assets (A*): $3,000,000
- Spontaneous Liabilities (L*): $800,000
- Net Profit Margin (M): 5%
- Dividend Payout Ratio (d): 40%
Here is the step-by-step calculation:
- Change in Sales (ΔS): $5,000,000 * 25% = $1,250,000
- Projected Sales (S₁): $5,000,000 + $1,250,000 = $6,250,000
- Required Asset Increase: ($3,000,000 / $5,000,000) * $1,250,000 = 0.60 * $1,250,000 = $750,000
- Spontaneous Liability Increase: ($800,000 / $5,000,000) * $1,250,000 = 0.16 * $1,250,000 = $200,000
- Increase in Retained Earnings: (5% * $6,250,000) * (1 – 40%) = $312,500 * 0.60 = $187,500
- AFN Calculation: $750,000 (Asset Needs) – $200,000 (Liability Funding) – $187,500 (Earnings Funding) = $362,500
The result shows that Growth Corp. needs to secure $362,500 in additional external funds to finance its expansion.
Interpreting the AFN Result
- Positive AFN: A positive number indicates a financing deficit. The company's internally generated funds are not enough to cover the asset growth required by the sales increase. The company must seek external capital, such as a bank loan (debt) or issuing new shares (equity).
- Negative AFN (Surplus): A negative number indicates a financing surplus. The company generates more than enough capital from operations and spontaneous liabilities to fund its growth. This surplus can be used to pay down debt, repurchase stock, increase dividends, or invest in new projects.
