Real-World Applications

Example: Creating a Monthly Budget

Scenario:
Income:
– Salary: R15,000
– Part-time work: R2,000
Fixed Expenses:
– Rent: R5,000
– Car Payment: R2,000
Variable Expenses:
– Groceries: R2,500
– Utilities: R1,000
Savings and Emergency Fund:
– Savings: R1,000
– Emergency: R500

Steps to Budget:
1. Total Income:
– R15,000 (salary) + R2,000 (part-time) = R17,000
2. Total Fixed Expenses:
– R5,000 (rent) + R2,000 (car) = R7,000
3. Total Variable Expenses:
– R2,500 (groceries) + R1,000 (utilities) + R1,000 (savings) + R500 (emergency) = R5,000
4. Total Expenses:
– R7,000 (fixed) + R5,000 (variable) = R12,000
5. Savings:
– R17,000 (income) – R12,000 (expenses) = R5,000 (surplus)


Common Misconceptions and Errors

  1. Ignoring Variable Expenses:
  2. Why: People often overlook variable expenses thinking they are less important.
  3. Strategy: Track all expenses for at least a month to identify variable costs accurately.

  4. Not Including Savings:

  5. Why: Assuming surplus income is enough for savings.
  6. Strategy: Allocate a fixed percentage of income to savings directly in the budget.

  7. Underestimating Emergency Expenses:

  8. Why: Optimistic planning without considering unforeseen expenses.
  9. Strategy: Always have a contingency amount set aside.

Practice and Review

Practice Questions:
1. List three examples of fixed and variable expenses in a household budget.
2. Given your monthly income is R20,000 and expenses are R18,000, calculate the budget surplus or deficit.
3. How much should you allocate to savings if you want to save 10% of your R15,000 monthly income?

Examinations Tips:
– Keywords: “income,” “expenses,” “budget surplus/deficit.”
– Prioritize sections with higher marks, typically the calculations vs. descriptive answers.
– Time management: Allocate approximate times per section according to marks.
