📐 Formula
💡 Practical Example
$1M sales, 20% growth → $1.2M projected. Asset need = $600K × 0.2 = $120K. Liab. increase = $120K × 0.2 = $24K. Retained = $1.2M × 8% × 60% = $57.6K. AFN = $120K - $24K - $57.6K = $38.4K.
📖 About Additional Funds Needed (AFN

💡 Financial Planning: Expert Principles & Risk Awareness
- All calculations assume fixed rates and idealized conditions. Real-world results vary due to market volatility, inflation, fees, and taxes.
- The Consumer Financial Protection Bureau (CFPB) recommends consulting a certified financial planner (CFP) for decisions involving significant sums.
- Run at least three scenarios: optimistic, pessimistic, and most-likely — to understand the full range of potential outcomes before committing.
- Inflation averages 2–3% annually in the US (Federal Reserve target). Long-term projections that ignore inflation significantly overstate future purchasing power.
- Tax treatment varies widely by account type (IRA, 401k, brokerage), jurisdiction, and income level. Verify tax implications with a CPA before acting.
- Compound interest works for you in savings/investments and against you in debt. The difference of even 1% in rate, sustained over decades, is enormous.
- Emergency funds (3–6 months of expenses) should be established before optimizing for returns — financial security precedes financial growth.
- Financial projections older than 12 months should be recalculated. Interest rates, tax brackets, and market conditions shift materially year to year.
