Process

  •  read the notes 
  • familiarize yourself with the terminology and formulas 
  • do the task given 

TERMINOLOGY 9income,expenditure,profit and loss)

  • personal income - money coming into a household, i.e. money received 
  • this includes

      -  salaries, wages and commission   - interest

      - bursaries and loans                         - gifts and pocket money

      - savings                                            - inheritance

 

there are three types of income 

  • fixed income - a constant income coming into the household e.g. monthly salary, weekly wages, etc.
  • variable income - an income that is not always the same e.g. completing a task, commission, interest on savings, etc.
  • occasional income - an unreliable form of income e.g. overtime, funds from an  inheritance etc. 

PERSONAL EXPENDITURE - money being spent or going out of the household 

this includes:

- living expenses

-accounts

-cellphone/telephone

-fees( school fees and bank fees)

- insurance

- savings

 

there are three types of expenditure

> fixed expenditure - an expense that is the same every week or month e.g. car repayment, monthly rent etc.

> variable expenditure - these are expenses that are expected every month, but are never constant , e.g. petrol, water etc.

> occasional expenditure - these are unexpected expenses tat do not occur every month e.g. burst geyser, broken down  car etc.

 

personal expenses can also be divided into:

> high priority expenditure - expenses that have to be paid , e.g. food, rent, loan repayments, insurance, electricity etc.

> low priority expenditure - these are expenses you can do without i.e. luxuries e.g. movies, DSTV, decorations, etc

 

PROFIT AND LOSS

profit - if  your income is more than your expenditure, you will make a profit ( i.e. you will have money left over at the end of the month /have a surplus)

.                                         profit = income > expenditure 

 

loss - if your income is less than your expenditure, you will make a loss (i.e. you will be in debt at the end of the month/ have a deficit)

                                      loss =  expenses> income 

 

the general formula used to determine if a profit or loss was made is:

                         profit or loss = income - expenditure 

- if the answer is positive, a profit was made

- if the answer is negative, a loss was made
