Explain household spending, saving and borrowing
Use income, interest rates, confidence, age and culture to explain household financial choices.
Cambridge IGCSE Economics 0455 / IGCSE (9–1) Economics 0987, 2027–2029 Version 1. Apply each model to the stated evidence and qualify conclusions where effects depend on context. Practice is original and self-checked; it is not a Cambridge paper, mark scheme or official grade.
Before you begin
- No prior economics study is assumed. Read the scenario for the decision-maker, the market or economy involved, the time period and the evidence supplied.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
If borrowing rates rise, what may happen to a household considering a variable-rate loan?
What you will learn
- Identify influences on household choices
- Explain spending, saving and borrowing links
- Use context without assuming every household responds alike
Households compare present and future choices
Income affects the amount available to spend, save or borrow. Higher interest rates can reward saving and increase some borrowing costs, but the effect depends on the account, loan and household's existing contract.
Confidence affects expectations about income and jobs. Age, family responsibilities and culture can shape priorities, but these are influences rather than fixed rules for every person.
Choices depend on constraints
A household may borrow to bring forward a purchase but must consider repayment capacity and interest. Saving delays consumption and can provide a buffer or future funds.
Explain the direction of a likely effect and name a condition. For example, higher income may raise saving if spending does not rise by the full amount.
Pause and explain
Why might two households respond differently to the same rate rise?
Worked example
A household receives a pay rise and has no change in interest rates. Explain two possible uses of the extra income.
Show the worked solution
- Disposable income increases, other things equal.
- The household may increase spending, saving or repay debt.
- The choice depends on confidence, goals and existing commitments.
Answer The household could spend more, save more or repay borrowing. A pay rise creates capacity but does not determine one choice for every household.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A household's variable mortgage rate rises. Explain one likely budget effect and one possible response.
Give me a hint
Consider required repayments and alternatives for remaining income.
Compare my reasoning
- The interest cost may raise repayments.
- Less income may remain for other uses.
- The household may reduce spending, use savings or adjust borrowing if possible.
Higher repayments may leave less disposable income for other spending or saving. The household could cut other expenditure or use savings, depending on its budget and options.
Look for these in your work
- Cost effect stated
- Budget link made
- Responses qualified
A confident household expects stable employment and receives a bonus. Explain why it might spend some and save some.
Give me a hint
Connect current funds with future expectations and precautionary saving.
Compare my reasoning
- The bonus raises available income.
- Confidence may encourage current spending.
- Saving can still provide future security or fund planned purchases.
The bonus allows more spending, and job confidence may make current consumption feel affordable. The household may still save for planned costs or protection against uncertainty.
Look for these in your work
- Income change recognized
- Confidence applied
- Saving motive included
A bank advertises a low-interest loan to two households, one with variable income and one with stable income. Explain why affordability may differ.
Give me a hint
Compare repayment risk and income timing.
Compare my reasoning
- The same repayment takes a different share of each budget.
- Variable income makes future repayments less predictable.
- Each household should assess its own obligations and buffer.
The variable-income household faces greater uncertainty about meeting fixed repayments. A loan that seems affordable from average income may be risky without a buffer; the stable-income household still needs to consider other commitments.
Look for these in your work
- Budget share considered
- Income uncertainty applied
- Risk-qualified conclusion
Common mistakes
- Assuming an interest-rate change affects all existing loans immediately
- Treating age or culture as destiny
- Confusing borrowing with income
