Cash Flow, Budgeting, and Debt Management
This domain tests whether you can build and interpret a personal cash-flow statement and net worth statement, set a budget, measure debt burden, size an emergency fund, and prioritize debt repayment. Questions often turn on the difference between gross and net income, which expenses are essential, and whether consolidation or refinancing actually helps.
Core rules and concepts
- Cash flow is inflows minus outflows over a period; net worth is assets minus liabilities at a point in time. A client can have positive net worth and negative cash flow, or the reverse.
- Common budget methods are zero-based (every unit assigned), envelope (cash categories), and percentage frameworks such as 50/30/20. The method matters less than whether actual spending is tracked and irregular costs are annualized.
- Housing ratio = monthly housing cost / gross monthly income. Total debt ratio = all monthly debt payments / gross monthly income. Lenders often use gross income, but affordability analysis should use net income and essential expenses.
- Emergency reserves typically cover three to six months of essential outflows, not income. Stable dual-income households may hold less; commission-only or single-income households more.
- Debt priority: protect secured assets and minimum payments first; then retire highest-cost unsecured debt (avalanche) or smallest balances (snowball) depending on behavior. Consolidation helps only if the rate, fees, and term improve and spending behavior changes.
- Amortization front-loads interest. Early payments on a long mortgage build little equity; extra principal has a guaranteed return equal to the interest rate.
- Credit utilization and payment history drive scores; closing old accounts can raise utilization.
Worked example
A client has gross monthly income 10,000, net 7,800, housing 2,600, other debt payments 900, and other essential living costs 3,000. Housing ratio is 2,600 / 10,000 = 26%; total debt ratio is 3,500 / 10,000 = 35%. Essential monthly outflows are 2,600 + 900 + 3,000 = 6,500, so a three-month reserve is 19,500. Cash on hand is 8,000, leaving a gap of 11,500. Monthly surplus is 7,800 - 6,500 = 1,300. Reasoning: direct the surplus to the reserve first while paying minimums, then attack the highest-rate debt; do not count the full 1,300 as free spending.
Traps that cost marks
- Mixing gross and net income in the same ratio.
- Forgetting annual, irregular, or seasonal expenses.
- Treating net worth as a cash-flow measure.
- Setting the emergency fund at one month for an unstable income.
- Assuming consolidation fixes overspending.
- Ignoring taxes, insurance, and retirement contributions in the budget.
