Households A, B, and C each own CNY 2.4 million in assets and have CNY 300,000 in accessible bank cash. C has the least debt and the highest net worth. If all three want to consider investment research, which household seems to have the most room?
Save your initial answer, even if it is “I need more information.” Now give each household's cash specific jobs. One has tuition due in two months; another has a large principal repayment. We will see whether a ranking by wealth answers the question of which money is actually available.
What you will be able to do
- Distinguish total assets, net worth, available cash, and future cash flows.
- Build reserves for a stated adverse scenario without assigning the same money twice.
- Update a household funding record when income, expenses, or existing investments change.
The essential skill is deciding which amounts belong in which calculation. You only need an initial understanding of simultaneous income and investment losses. This chapter does not derive an optimal allocation or require a forecast of market returns.
Begin with the balance sheet
All households, amounts, valuations, and stress assumptions are synthetic. Values are measured in Chinese yuan as of October 28, 2026. The amounts remain in CNY, matching this example's household obligations. Property and security values are supplied estimates; selling costs are unspecified. The exercise allocates existing bank cash only. It does not sell the home, securities, or restricted account.
Every household has the same four assets: an owner-occupied home valued at CNY 1,800,000, accessible bank cash of CNY 300,000, existing stocks worth CNY 200,000, and a restricted account holding CNY 100,000. Together, they total CNY 2,400,000. Stocks have not been sold, so their value is not added to the bank balance.
| Household | Debt balance | Net worth |
|---|---|---|
| A | CNY 600,000 | CNY 1,800,000 |
| B | CNY 1,000,000 | CNY 1,400,000 |
| C | CNY 200,000 | CNY 2,200,000 |
Net worth is assets minus liabilities at a given date. A household balance sheet lists what is owned and owed together; Investor.gov uses this distinction in its explanation of a net worth statement.[1] The statement is a snapshot. It does not yet show when cash will run short.
C's CNY 2.2 million stands out, but most of its assets are not immediately available for bills. A home cannot simply pay next week's expense without a sale, time, costs, and different housing arrangements. We also do not assume early access to the restricted account. For this cash exercise, all three households therefore start at CNY 300,000, not at total assets or net worth.
Now add a payment calendar. Cash flow describes when money comes in and goes out. Timing is central to the CFPB's discussion of managing cash flow.[2] A household can own valuable assets and still face a payment before an expected inflow arrives. The balance sheet and calendar answer related but different questions.
Give current cash a purpose and a date
Record known payments before deciding what the unlabeled balance might do. Do not add paychecks that have not arrived to today's cash. The households have these upcoming requirements:
| Cash requirement | A | B | C |
|---|---|---|---|
| Ordinary payments over the next 30 days | CNY 20,000 | CNY 25,000 | CNY 15,000 |
| Separate known expense after that period | CNY 60,000 | CNY 50,000 | CNY 120,000 |
| Separately listed principal repayment | None | CNY 120,000 | None |
A's separate CNY 60,000 expense occurs in month four. B pays CNY 50,000 in month two and CNY 120,000 of principal in month three. That principal is already included in B's CNY 1,000,000 debt balance. C's CNY 120,000 is tuition due in month two. The separate expenses exclude ordinary monthly payments and the unexpected expenses introduced below.
Ordinary payments include living expenses, family responsibilities, and regular monthly debt principal and interest. They exclude B's separately listed CNY 120,000 repayment. This distinction prevents the same repayment from being reserved twice.
All three households fund the next 30 days entirely from current cash, without offsetting income that has not yet arrived. The later income-interruption scenarios begin on day 31. The initial payment reserve and the stress-period reserve therefore cover different periods. Without that timing convention, adding both could quietly double count the same month.
Expected wages stay in the future-inflow column. Even if total monthly income eventually exceeds expenses, a bill can arrive before the paycheck. Keep dates attached to both sides. Subtracting miscellaneous totals from two different records cannot produce a reliable amount of “investable assets.”
Known bills are only part of the reserve
Some cash has a purpose even though no bill has arrived. An emergency fund is cash set aside for unexpected expenses or financial emergencies. The CFPB gives repairs, medical bills, and income loss as examples and explains that the amount depends on circumstances.[2] Here, we use specific household scenarios rather than a universal number of months.
A assumes its main income stops for four months beginning on day 31. Necessary payments remain CNY 20,000 each month, including regular debt payments. A relatively independent source brings in CNY 8,000 before each month's payments. The monthly gap is therefore CNY 12,000. Four months require CNY 48,000. Add a separate unexpected repair of CNY 12,000, and A's stress reserve is CNY 60,000.
The four months and repair cost are teaching inputs. In an actual record, investigate how long income replacement might take, whether another earner could be affected, which expenses can change, and when insurance or support would really arrive. An uncertain reimbursement cannot be treated as confirmed cash merely because it would make the budget balance.
B has a six-month stress period. Necessary payments are CNY 25,000 a month, with reliable inflows of CNY 5,000. The CNY 20,000 monthly gap totals CNY 120,000. A separate unexpected expense of CNY 20,000 raises the reserve to CNY 140,000.
C has a three-month stress period. Monthly payments of CNY 15,000 less reliable inflows of CNY 5,000 leave CNY 10,000 a month. Three months require CNY 30,000; adding an unexpected CNY 15,000 gives CNY 45,000.
Check how the separate expense fits inside the stress calendar. A's month-four bill can arrive during the income interruption, but it was excluded from the CNY 20,000 monthly payment assumption. It therefore still needs its own reserve. The same reasoning applies to C's tuition and B's large principal payment. An expense occurring during a stress period is not automatically included in that period's monthly gap. Read the definition of the monthly payments before either adding the expense or declaring it already covered.
Reconcile each household to CNY 300,000
A reserves CNY 20,000 for the first 30 days, CNY 60,000 for its known expense, and CNY 60,000 for stress. Total reserves are CNY 140,000, leaving CNY 160,000. Reserved uses plus the remainder equal the CNY 300,000 starting cash. No money has been created by labeling it.
B needs CNY 25,000 plus CNY 50,000 plus CNY 120,000 plus CNY 140,000: CNY 335,000 in total. It has a CNY 35,000 shortfall. C needs CNY 15,000 plus CNY 120,000 plus CNY 45,000, totaling CNY 180,000 and leaving CNY 120,000.
Identical total assets have produced three different cash results: A has CNY 160,000 unassigned under the listed assumptions, B is short CNY 35,000, and C has CNY 120,000 unassigned. B's negative number is a funding problem, not permission for a negative investment budget. Check adjustable spending, repayment arrangements, and other genuinely accessible resources, then recalculate. An unapproved loan has not solved the gap.
Return to your initial ranking. C's net worth exceeds A's by CNY 400,000, yet C's remaining cash is CNY 40,000 lower. Tuition and income conditions explain the difference. Net worth remains useful; it simply did not answer the payment question by itself.
Has the debt already been deducted?
B's principal repayment raises a reasonable objection: Didn't we subtract debt when calculating net worth? Follow the two records rather than trying to remove the apparent repetition by deleting a real bill.
A's CNY 600,000 debt was deducted from assets to calculate CNY 1,800,000 of net worth. That does not require paying the full CNY 600,000 from today's CNY 300,000 cash. The calendar records only principal and interest actually due during the relevant periods. A new decision to repay early would create a separately dated payment.
The reverse shortcut is wrong too: debt appearing on the balance sheet does not make monthly repayments disappear from the calendar. The balance sheet measures outstanding obligations; the calendar schedules cash needed to meet them. Double counting occurs if you start with net worth as though it were cash and then deduct the same principal again without explanation.
B's CNY 120,000 appears once in outstanding debt and once as a scheduled payment, for different purposes. To calculate the cash gap, we deduct that payment once from CNY 300,000. We do not also deduct all CNY 1,000,000 of debt. When principal is paid, both cash and the outstanding principal balance change. Updating only cash would leave the balance sheet inconsistent.
Apply the same check to tuition. It cannot be fully reserved as a near-term goal and again as part of an emergency allowance. If a scenario includes it, identify the overlap and count it once. Our example deliberately separates ordinary payments, known expenses, principal repayment, and unexpected costs so each yuan has a clear assignment.
Why A's remainder is not an investment recommendation
A's CNY 160,000 is cash with no assigned use under the listed conditions. It is not advice to buy CNY 160,000 of securities. Longer-term goals, access restrictions, acceptable losses, and research evidence still need attention. Allocating zero to an unverified strategy remains a possible result.
Suppose A's existing CNY 200,000 of stocks falls 40% during the income interruption. The investment loses CNY 80,000 in market value. Now suppose CNY 60,000 of the remainder had also been assigned to a new strategy and falls 50%, losing CNY 30,000. Combined investment losses are CNY 110,000. Neither stress percentage is a maximum-loss guarantee or an allocation recommendation.
Without a sale, the existing stock loss is not an extra living-expense cash outflow. It reduces security value and the household's financial room. If the stock is concentrated in an employer, a single event might damage employment and the share price together. Keeping investments in separate accounts does not establish independent risk.
B cannot solve the problem simply by saying it will sell stocks if necessary. A 40% decline would reduce its CNY 200,000 position to CNY 120,000 before any sale. Price, fees, and availability of proceeds would still matter. The old balance-sheet valuation cannot guarantee the cash available during a forced sale.
Test the plan with changed conditions
First explain what is missing from this claim: “C has the most net worth, so it can put more cash into investments than A.” Then assess: “A can label the same CNY 60,000 as emergency money and strategy backup because only one use normally happens at a time.” Write reasons before checking the discussion.
The first claim misses tuition and payment timing. Under the supplied conditions, C has CNY 120,000 remaining versus A's CNY 160,000. The second promises the same money twice. Investment losses and income interruption can occur together; money needed for essential payments cannot simultaneously guarantee a strategy's funding.
Now change A's circumstances. From day 31, reliable monthly inflows fall to zero and the interruption lasts six months. Add CNY 30,000 of care expenses due in month three, excluded from both ordinary monthly payments and the original known expense. Everything else stays the same. Recalculate stress reserves, total reserves, and the remainder. Should the earlier CNY 60,000 strategy assignment carry over automatically?
Reference answers · reveal
Answer guide: Six months of CNY 20,000 gaps require CNY 120,000. Add CNY 12,000 for repairs to get CNY 132,000 of stress reserves. The first-month CNY 20,000, original CNY 60,000 expense, new CNY 30,000 expense, and stress reserve total CNY 242,000. Cash remaining is CNY 58,000, a decrease of CNY 102,000.
The former CNY 60,000 strategy assignment now exceeds the remainder by CNY 2,000. Stop carrying it forward and review the plan. Expected strategy profits cannot fund the difference in advance. The new CNY 58,000 figure is still a remainder under stated assumptions, not a recommended investment amount.
Save a funding record you can update
Use paper or an ordinary document. You need not give a tool real account information. Record the date and currency, asset values and debt balances, accessible cash, each use's amount and date, the income-interruption scenario and reliable inflows, overlap checks, the remainder or shortfall, and an event that would trigger recalculation.
Reconcile unique reserves plus the remainder to starting cash. If reserves exceed cash, display the shortfall separately rather than changing the sign to make a positive investment allowance. Check that future wages have not entered current cash, the whole debt balance has not been deducted again, and existing security risks remain visible. Keep both the initial record and the changed-condition version, including your answers.
A method for the next household decision
Use a balance sheet to understand overall resources and obligations, then dates and scenarios to test payments. The two records complement each other; neither replaces the other, and their totals cannot be mechanically combined.
Assign money to distinct uses and examine events that can happen together. A remainder shows only what is left after the needs you listed. When income reliability, payment timing, or existing holdings change, update inputs and recalculate. If a key condition is unknown, keep it unresolved rather than substitute a universal allocation percentage.
