About AFN

The Additional Funds Needed (AFN) formula estimates how much external financing a firm requires to support a specified sales growth, accounting for spontaneous liabilities and retained earnings.

This estimate helps in planning financing mixes and assessing whether internal resources suffice for growth.

How to Use

  1. Provide current sales and expected growth rate.
  2. Fill total assets and spontaneous liabilities to compute ratios.
  3. Enter net income and dividend payout to estimate retained earnings.
  4. Review AFN to determine external financing needs.
  5. Use scenario growth rates to plan alternative funding strategies.

Example

Current sales $1,000,000, growth 20%, assets $500,000, liabilities $200,000, net income $80,000, payout 30% → AFN ≈ $X (calculation shown in widget).

FAQs

What does AFN include?

Is AFN exact?
