Good decisions require good information

Can a household afford a loan?

Suppose the Rivera household needs a car so that one adult can travel to work. The Riveras find a car with a monthly loan payment of $480. They want to know whether they can pay it without missing rent, food, utility, or other debt payments.

The payment amount matters, but it does not answer the question. The household also needs to know how much cash comes in, how much normally goes out, when those amounts occur, and what could change. A list of those facts can help the Riveras make a decision. The list cannot make the decision for them.

Accounting begins with this need. People face economic events: they earn, spend, borrow, lend, buy, sell, and promise to pay. Accounting is a way to identify, record, and organize information about those events. The result can help someone examine a choice or explain what has already happened.

By the end of this chapter, you should be able to

  1. name the user, entity, decision, period, useful records, and limits in a simple accounting question; and
  2. explain why two users may need different information about the same event.

Before collecting numbers, ask six questions:

  1. Who will use the information?
  2. Whose activity will the information describe?
  3. What decision must the user make?
  4. What period does the decision cover?
  5. Which records can help with that decision?
  6. What will those records leave unanswered?

These questions prevent a common mistake: collecting many numbers without knowing what they are meant to explain.

Before collecting numbers

Six questions, asked of the Rivera loan

  1. User

    Who will use the information?

    For the Riveras: The Rivera household.

  2. Entity

    Whose activity will the information describe?

    For the Riveras: The household itself, not the restaurant that employs one adult.

  3. Decision

    What decision must the user make?

    For the Riveras: Whether to take on a $480 monthly car payment.

  4. Period

    What period does the decision cover?

    For the Riveras: One planned month first, then a longer view for costs that arrive a few times a year.

  5. Records

    Which records can help with that decision?

    For the Riveras: Pay records, bank statements, bills, debt statements, and the loan offer.

  6. Limits

    What will those records leave unanswered?

    For the Riveras: Future work, an emergency, and costs the plan has not listed.

The order matters. The user and the entity fix whose decision this is before any amount is listed.

Is the payment amount enough?

Whose activity belongs in the household records?

The Rivera household is the entity in this example. An entity is the person, household, business, or other organization whose activity the records describe.

The boundary matters. One Rivera adult may work for a restaurant, but the restaurant's cash does not belong to the household. A relative may be willing to help in an emergency, but that possible help is not cash the Riveras control today. The lender has its own records and its own view of the proposed loan.

Naming the entity tells us what belongs inside the record. It also tells us what must stay outside or be identified separately.

Separate the household from the company

Which months and costs belong in the plan?

The loan decision needs information for a stated span of time, called a period. A one-month view can show whether cash normally received each month covers normal monthly payments. A longer view can reveal costs that do not occur every month, such as an insurance bill or a car repair.

The Riveras first prepare this monthly view:

Monthly item Cash effect
Take-home pay and other regular cash received +$4,200
Rent, food, utilities, current debt payments, and other regular cash payments -$3,450
Cash left before the proposed car payment $750
Proposed car payment -$480
Cash left after the proposed car payment $270

The arithmetic is:

$4,200 − $3,450 − $480 = $270

The Rivera cash plan

One month, three amounts, one remainder

The Rivera cash plan as a bridge $4,200 Cash received −$3,450 Regular payments $750 Before the car −$480 Car payment $270 Cash left Amounts for one planned month. The bars are to scale.
The plan has a clear boundary: the Rivera household, one planned month, and the listed amounts. That is what makes its $270 useful, and also what limits it.

This calculation describes one planned month. It does not prove that the loan is affordable. The Riveras still need to examine the down payment, loan length, interest, insurance, fuel, repairs, changes in income, and costs that arrive only a few times each year. They must also decide how much room they need for an emergency.

The calculation is useful because its boundary is clear. It describes the Rivera household, covers one planned month, and answers a limited question: how much cash remains after the listed amounts.

Interpret the $270 remainder

Which records support the loan decision?

Useful information needs support. The Riveras could examine pay records, bank statements, bills, debt statements, and the written loan offer. Each record answers part of the question.

Which records support the decision

Each record answers part of the question

  • Pay records

    Shows
    Recent take-home pay.
    Cannot show
    They cannot guarantee future work.
  • Bank statements

    Shows
    Cash received and paid through the account.
    Cannot show
    They may not show a bill that has not yet been paid.
  • Bills and debt statements

    Shows
    Amounts due and their payment dates.
    Cannot show
    They show what is owed, not whether it can be paid.
  • The loan offer

    Shows
    The proposed payment, interest rate, fees, and term.
    Cannot show
    It cannot decide how much risk the household should accept.
No single record gives a complete answer. Judgment decides which evidence belongs in the record and what each piece can support.

No single record gives a complete answer. A bank statement shows what happened in the account, but it may not show a bill that has not yet been paid. A pay record shows past pay, but it cannot guarantee future work. A loan offer gives contract terms, but it cannot decide how much risk the household should accept.

Accounting requires judgment about which evidence belongs in the record and what each piece of evidence can support.

Why do the household and lender need different records?

Suppose the Riveras accept the loan and buy the car from a dealer. One event now affects several people and organizations.

Why the household and lender need different records

One event, five positions

The event

The Riveras accept the loan and buy the car from the dealer.

Rivera household

Needs to know Cash paid now, future loan payments, and the car available for use.

Car dealer

Needs to know The sale, the car delivered, and the amount received or still due.

Lender

Needs to know The amount lent, payments received, and evidence about repayment.

Regulator

Needs to know Whether the lender and dealer followed the rules that apply to them.

Statistical agency

Needs to know How the purchase fits into broader measures of household and business activity.

The household's amount owed is the lender's amount to collect. The household's purchase is the dealer's sale. Each entity records its own position.

The event is connected, but each entity has a different position in it. The household's amount owed is the lender's amount to collect. The household's purchase is the dealer's sale. A regulator asks whether rules were followed. A statistical agency combines information from many households and businesses to describe part of the economy.

Accounting information must name its user, entity, purpose, and period. A number without that setting can be misunderstood.

Separate the borrower from the lender

What can the records show?

Accounting can organize evidence about resources, amounts owed, cash received, cash paid, income, costs, and changes across periods. Later chapters will give these ideas more exact names and show how businesses place them in connected financial statements.

Accounting can help a person ask better questions:

  • What happened?
  • Which entity did it affect?
  • When did it happen?
  • What amount can the records support?
  • How does it change the decision?
  • What remains uncertain or outside the record?

Accounting does not measure every kind of value. The Riveras' health, time, family needs, and confidence in future work matter even when no accounting record gives them a complete amount. A report can support a choice without settling it.

Can the Chens afford a $350 monthly payment?

The Chen household is considering a $350 monthly loan payment for a home repair. Its members have gathered a recent pay record, one bank statement, the loan offer, and the latest utility bill. They have not yet listed annual insurance payments or possible changes in work hours.

Answer these questions before opening the feedback:

  1. Who will use the information?
  2. Which entity should the record describe?
  3. What decision is the household trying to make?
  4. What period should the household examine?
  5. What can the gathered records help show?
  6. What important facts remain outside the record?
Compare your reasoning with the worked answer

The Chen household will use information about its own activity to consider the loan. It needs a period long enough to include normal monthly costs and costs that arrive only a few times each year. The records can support recent pay, account activity, one utility cost, and the proposed loan terms. They do not yet give a complete view of recurring and occasional costs. Changes in work hours also make future cash received uncertain. A useful next step would be to choose a period and build a cash plan for it. The household should also add known costs from outside that period.

Next: Choose what belongs in the records

You can now start an accounting question by naming the user, entity, decision, period, records, and evidence limit. The next chapter asks a question that controls every later record: whose activity belongs inside the accounting boundary?

Sources and scope

The Rivera and Chen households are fictional. Their amounts exist only to teach the method.
