Income and expenses
| Income | Meaning |
|---|---|
| Salary | Fixed amount every month |
| Wage | Per hour or day |
| Commission | A percentage of every sale |
| Rent | Someone pays you to live in your flat |
| Interest | The bank pays you on savings |
| Essential | Non-essential |
|---|---|
| Food for the family, rent | Branded takkies when you have good shoes |

Drawing up a budget
| Item | Amount |
|---|---|
| Rent | R4 000 |
| Food | R3 000 |
| Transport | R1 500 |
| Savings | R500 |
| Total budgeted | R9 000 |
Put a little aside for emergencies: unexpected costs always come along. Compare your budget with what you really spent, to see where you overspent. A surplus of R800? Save it or pay off debt.
A stall’s statement
Thandi sells 40 cupcakes at R12: income R480. A stall takes in R950; ingredients cost R420 and the table R80: profit R950 − R500 = R450. Income R600 and expenses R750: a loss of R150.
A personal budget plans a household’s money; a business budget a business’s.
A business’s income, expenses and savings
| Income a business receives | Expenses a business has |
|---|---|
| Sales: goods that were sold | Rent for the premises |
| Fees for services provided, like a haircut | Wages and salaries |
| Rent income: part of the building is rented out | Water and electricity |
| Interest income on money in the bank | Telephone, advertising and stationery |
| Commission income for selling someone else’s goods | Bank charges and interest on loans |
A business saves too: it puts part of its profit aside for emergencies, new equipment or growth. It can invest the money in a fixed deposit at the bank to earn interest, or invest it back into the business, for example by buying a second oven so that it can bake more.
Remember this and test yourself
- Salary: monthly; wage: per hour or day; commission: a percentage of each sale; also rent and interest.
- Fixed expense: rent. Variable expense: electricity.
- Surplus: R14 000 − R12 500 = R1 500 left. Deficit: R8 000 − R8 600 = R600 short.
- Balanced budget: income = expenses. Deficit? Cut non-essential spending first.
- An income and expenditure statement shows what was really earned and spent.
Write these points in your book. Read them again the night before the test.

Surplus = money left over. Deficit = money missing.
