Main Content Sections

1. Understanding Budgeting

  • What is a Budget?
    A budget is a financial plan that helps individuals manage their income and expenses. It ensures that you do not spend more than you earn.
  • Creating a Budget:
  • List all sources of income (e.g., salary, gifts).
  • List all monthly expenses (e.g., rent, food, utilities).
  • Create a plan for saving a certain amount each month.

2. Interest and Loans

  • Types of Interest:
  • Simple Interest: Calculated only on the principal amount.
    • Formula: ( I = P \times r \times t )
      Where ( I ) is the interest, ( P ) is the principal, ( r ) is the rate, and ( t ) is the time.
  • Compound Interest: Calculated on the initial principal, which also includes all the accumulated interest from previous periods.
    • Formula: ( A = P \left(1 + \frac{r}{n}\right)^{nt} )
      Where ( A ) is the amount of money accumulated after n years, including interest.
  • Example of a Loan Calculation:
    If you take out a loan of R5,000 at an interest rate of 10% per annum for 3 years using simple interest, calculate:
    ( I = 5000 \times 0.10 \times 3 = R1500 ).
    Total repayment = Loan + Interest = R5,000 + R1,500 = R6,500.

3. Savings and Investments

  • Savings Accounts:
    These accounts earn interest and are a safe place to store money while earning some return.
  • Investing Basics:
    Investing involves purchasing assets like stocks, bonds, or property to generate returns. The risks vary but can yield higher returns than savings accounts over time.

Example Problems or Case Studies

  1. Budgeting: Mary earns R10,000 monthly. She spends R4,000 on rent, R2,000 on transportation, R1,500 on groceries, and intends to save R1,500. How much can she spend on entertainment?
  2. Interest Calculation: James invests R8,000 in a savings account with an interest rate of 5% compounded annually. How much will he have after 2 years?
