Spending, Saving & Borrowing (Cambridge (CIE) IGCSE Economics): Revision Note

Disposable income is the money that households have left over from their salary/wages after they have paid their taxes and have received any transfer payments/benefits from the government

Consumption increases as disposable income increases and decreases as disposable income decreases

Interest rates are set by the government's Central Bank

Changes to the base rate cause commercial banks to change the lending rates they offer customers

If interest rates increase, the cost of borrowing increases

• Higher borrowing costs = less consumption

If interest rates increase, the monthly repayment on any existing loan increases

• Higher loan repayments = less consumption

The stronger the economy, the higher consumer confidence

• Consumers feel secure in their jobs and are confident of receiving regular salary payments, so consumption increases

In a weakening or recessionary economy, consumer confidence falls

• Consumers feel less secure in their jobs and consumption decreases 

Refers to the proportion of people in different age groups within the population

• Young populations → Higher spending on education, leisure, and starter homes; lower savings

• Ageing populations → More spending on healthcare and pensions; possibly less spending on consumer goods

Can influence the types of products and services in demand and the level of overall consumption in the economy

• E.g. Japan’s ageing population leads to higher demand for healthcare services and elderly care facilities, while youth-oriented markets are smaller

Culture refers to the shared values, beliefs, and traditions of a society

Cultural attitudes towards saving vs. spending directly affect consumption patterns

In cultures where saving is prioritised (e.g. many East Asian countries), households may spend less of their disposable income

In cultures with a strong consumerism trend, households are more likely to spend on non‑essential goods and services

E.g. In the USA, cultural emphasis on consumer spending drives high levels of credit card use; Germany’s culture encourages saving, leading to lower household debt

Higher disposable income allows households to save more after covering essential expenses

Lower disposable income means less money available for saving

• E.g. A salary increase enables a family to deposit more into a savings account each month

Higher interest rates encourage saving because the return on savings is greater

Lower interest rates discourage saving as returns are smaller, making spending more attractive

High consumer confidence → households may save less and spend more

Low confidence (e.g. during a recession) → households may increase saving as a precaution (precautionary saving)

Younger people often save less and prioritise spending on education, housing and leisure

Middle‑aged individuals may save more for retirement

Retired individuals might reduce saving and draw on past savings

Cultures that value saving (e.g. Japan, Germany) → higher proportion of income saved

Consumption‑oriented cultures → lower savings rates

Higher disposable income increases ability to borrow because lenders see borrowers as lower risk and repayments are more affordable

Lower disposable income reduces ability to borrow, as repayments may be harder to meet

E.g. A pay rise may make it easier for a household to qualify for a mortgage

Higher interest rates discourage borrowing because the cost of repaying loans is greater

Lower interest rates encourage borrowing as repayments are cheaper

E.g. Lower mortgage rates may lead to more people taking out home loans

High consumer confidence → more borrowing as households feel secure in their income and future job prospects

Low confidence (e.g. during a recession) → less borrowing as households fear they may not meet repayments

Younger people may borrow more for education, housing or setting up homes

Middle‑aged individuals may borrow for business expansion or large purchases

Older individuals may borrow less due to lower income in retirement and reduced access to credit

In cultures where borrowing is socially acceptable and credit is widely available (e.g. USA), borrowing levels tend to be higher

In cultures that value debt‑avoidance and financial prudence, borrowing is less common
