Activity 26. The Sunday Times reported on 24th February 2008 reported

that tobacco tax rates in South Africa increased 250% during the 1990’s to just under 50% of the retail price. They also reported that cigarette consumption fell 5% to 7% for every 10% increase in the price of cigarettes, resulting in a sharp decline in consumption, with the largest decrease among the youth and the poor.

• Sales documents– Invoices– Debit notes – Credit notes– Receipts – Till rolls

• Purchase documents– Petty cash slips / vouchers– Purchase orders– Dispatch notes and invoices– Credit and debit notes

• Banking documents– Bank statements– Cheque payments

Tips to help your reduce your banking fees

• Use your own bank’s ATM and not a Saswitch ATM.• Withdrawing money inside the bank is more expensive than at the

ATM outside the bank.• Withdrawing money at one or two of the big supermarkets is cheaper

than at an ATM.• Paying with your debit card is cheaper than withdrawing money and

paying cash.• It is cheaper to withdraw one lump sum than to withdraw small

amounts at short intervals.• Use ATM slips instead of asking for mini bank statements.• It is cheaper to have money paid into your account electronically than

to be paid by cheque which you then deposit inside your bank.• Avoid the cost of denied-transaction ATM fees by knowing how much

you have in the bank.

6. Savings

• Tips on staying out of debt:– Work out exactly how much this debt is costing you. – If you have more than one debt such as hire-purchase

agreements which you are paying off by month, it might be better for you to get a loan from your bank to pay off all of these debts and then repay only the one bank loan. It is called consolidating your debt.

– Don’t ever be tempted to buy on credit.– Be careful when taking out insurance of some sort, first talk

to a trustworthy person who has the necessary knowledge. – Take debt seriously. Pay it off as quickly as at all possible. – Don’t start saving before paying off all of your debts.

6. Savings• Tips on saving

– You have to start saving at a young age if at all possible.– Save R10 out of every R100 that you earn, i.e. 10%.– Compare the interest rates on the savings accounts of different

banks and use the bank with the best/highest interest rate. – Never use a micro loan business. They make their living from

charging extremely high interest rates on the money loaned to you.– Do not borrow money if not absolutely necessary. The high

interest charged will destroy you financially. – Do not ever be tempted to get a credit card. The extremely high

interest rates on this kind of debt will destroy you.– Do not ever buy on hire-purchase. Save the cash and buy cash.– Earthly possessions are rarely worth going into debt for.

6.1 Simple and compound interest

• Simple interest = P x T x R / 100

• Compound interest A = P(1+R/100)n

Activity 6

1. Calculate the interest amount on R55 500 in a fixed deposit at 8% p.a. for five years. Calculate the interest on a monthly basis.

R27 686.43

Activity 6

2. Calculate the interest rate if R7 000 increases to R15 000 in 5 years. Interest is calculated on an annual basis.

Activity 6

3. Calculate the value after 4 years of a car that cost R65 000. Devaluation is 6% p.a.

R50 748.68

Activity 6

4. Calculate the amount that has to be invested to have R45 000 available after 5 years at an interest rate of 10% p.a. calculated on a monthly basis.

P = A(1+r)-n P=45000(1.01) -5 P=27 941.46

Activity 65. In May of 2005 the debt level of South Africans was 57%. This

means that 57 cents out of every rand that South Africans earned went into payment of debt. In October of 2005 this level had risen to 62%. In October 2007 it was 76,5% which means that R76,50 out of every R100 earned, goes directly into payment of debt. In March 2008 the Reserve Bank reported that the amount that people were paying to service their debt had risen to an all-time high of 80% of disposable income.

• Draw a broken line graph of this information with debt level percentage on the vertical axis. Remember to scale the horizontal time axis correctly, i.e. the same time period earns the same gap on axis.

• Make a prediction for the average debt level in the middle of 2009.• If a person with the average debt level for 2008 gets a salary of R8 800 per

month, how much of this does he spend in debt payment?

Activity 6

6. The ratio of saving to spendable income is only 0,2% in South Africa, and the gap between savings and debt is increasing.a. Calculate how much a person saves if his

salary is R8 800 per month.

b. How much should he save per month? R17,60

Case Study: The extraordinary power of compound interest

• One of the big banks in South Africa have the following two examples on compound interest.– Monthly payment option:

• Investor A starts with a payment of R250 per month, and this is automatically increased by 10 % each year over a total investment term of 15 years.

• Investor B starts with a payment of R350 per month, and this is automatically increased by 10% each year over a total investment term of 15 years.

– Draw up two tables and calculate the balance in the bank accounts of the two investors at the end of each year (monthly calculation of interest).

– Draw two graphs to illustrate the increase in the investment.– Calculate the ratio between the final amounts of the two investors

as well as the ratio between the total payments by the two investors.

– Comment on your results.

2. Single-payment option:– Investor A chooses an investment term of 15 years and a

single payment of R10 000– Investor B chooses an investment term of 15 years and a

single payment of R15 000.a. Draw up two tables for the balance and calculate the balance

in the bank accounts of the two investors at the end of each year (monthly calculation of interest).

b. Draw two graphs to illustrate the increase in the investments.c. Calculate the ratio between the final amounts of the two

investors as well as the ratio between the starting amounts of the two investors.

d. Comment on the results.

Case Study: Inflation

1. What are grain products and why are they called “staple” foods.

2. What is the Reserve Bank’s inflationary target?3. Is inflation on the increase or decrease? Draw a

small bar chart to illustrate your conclusion.4. What does CPIX stand for? Explain the concept.

In April of 2008 the CPIX was 10,4%. a. How much higher is this than the Reserve Bank’s top

target limit?b. What is the percentage increase since January of

2008?


5. Four food items are mentioned in the first excerpt. What is the average increase of these four food items? Explain why this is not the average food increase but the top of the range.

6. If a bottle of cooking oil costs R19,98 in February 2008, what did it cost 12 months ago in February 2007? And what was the price of this bottle of oil in March 2006?

7. In the second week of June 2008 oil traded at $132 per barrel. Calculate the % increase between 27th March and the second week in June of 2008. If the price of oil increases to $200 a barrel then the price of petrol will be R16 per litre. Calculate the percentage increase in barrel price of oil between March and June of 2008.


8. If Beverley has to commute 10 km per day to and 10km back from work and the petrol consumption of her car is 10km per litre, calculate what her monthly cost will be at R10 per litre and also at R16 per liter. Calculate the percentage increase in monthly expense towards petrol for Beverley.

9. Will Beverley still be able to work at the same place or will she have to listen to Mr. Thabo Bolani the chairman of the National Consumer Forum in Pretoria who said that consumers had to get alternative methods of transport?

10. Calculate the average percentage rise for the items in the table. Why is it so much higher than the announced inflation rate of 10,4%?

How to look at an income statement

• Identify and concentrate on pertinent totals before getting involved with details. Start at the “bottom line” – does the income statement show a profit or a loss?

• Next, assess whether it is an acceptable profit. Alternatively, if a loss was made was this expected?

• Next, look at the total income, then at the total expenses, and do a quick mental calculation to ascertain whether these are the two figures that have resulted in the net profit or loss.

• Proceed to examine the individual income and expense items.

Financial results can be judged against

• Industry standards,

• The previous year’s financial information,

• Goals (budgets) set at the beginning of the financial period.

8. Budgets

• A budget can apply to a single event such as a hot-dog stand at a Saturday morning market.

• An individual has to decide how he must spend his income so as to avoid running into debt – he sets up a budget.

• A household has to budget its monthly expenses against its income.

• The company you work for will also have an annual budget.

• The municipality that you live in has a budget. • Similarly, a country has to produce more than it uses -

and thus the government has to gain more in revenue than it spends.

Case Study: Beverly’s personal budget

• Beverley is worried that she will not be able to manage all her expenses on her monthly net income of R4279, 61

• Beverley has been given the advice to write all of her expenses in a small book. She did so for May, June and July and has calculated the average spending per month for the different categories.

• You have to help her organise a budget that she can stick to.

• Beverley’s average expenses for three months running:


• Draw up a table with the above items organised into “fixed expenses” and variable expenses” and “irregular expenses”. Irregular expenses are those that are made once per year such as TV license. For these irregular expenses calculate how much Beverley must pay per month or put away per month so that she does not have to take the full amount out of one month’s pay.

2. How much does Beverley have left for clothes (x) and savings (y)?

3. Where can she cut down on expenses to be able to buy some clothes and to start saving?

4. Make a plan for her so that she can have R100 per month to put away as savings and R250 every three months for clothes.

5. The inflation rate is 10,5%. Calculate for her a reasonable request for an increase in salary at the end of February of the next year.

6. The price of petrol suddenly increases from R5,85 to R10,00 within six months’ time. Calculate the percentage increase in petrol and her adapted monthly petrol expense.

Activity 8

• Complete the table by filling in the columns on variance amount, % variance and % expenditure for the National budget.

Activity 9

• You want to set up a table at a regular Saturday market– Decide what you want to sell

– Draw up a budget for this small project

– Include expenses and income as well as net profit or loss

Case Study: Interpret the news 3

• From The Sunday Times of 17th February 2008 comes this small report. An old lady in KwaZulu Natal shares her house – and her pension of R870 – with a daughter and five great-grandchildren. Everyone else has died. The only income for the small household is the pension of Anna Zikhali who will turn 95 later this year.

• Anna Zikhali knows exactly what her pension can buy: 50kg of mealie meal at R238; 5kg of sugar beans at R49; 5 litres of cooking oil at R42; and a bag of potatoes at R32. School fees are R60 per year, a pair of Toughie school shoes costs R120 for each child, and there are shorts, dresses, shirts, jerseys and a few other clothing items. After that there is not much left.


a. Divide her expenses into fixed (which here includes irregular expenses) and variable expenses.

Fixed: School shoes; Variable: mielie meal; sugar beans; cooking oil; potatoes; school clothes


b.Which other expenses not listed here, must she have? For example, consider the following in your answer: she lives far from the pension pay-out point and from the clinic and the school; she has to cook the food; they have no electricity but they want to see at night so that home-work can be done by the children; illness.electricity/gas; replacement of damaged utensils, cutlery, candles; possible occasional taxi


c. Draw a pie chart of only her food expenses.


d. What plan can you make for the children when Anna dies? Look at question e.

Child welfare; foster-care grants


e. The 2008 budget gives R62 million to more than 12 million people in welfare grants.– 2,2 million pensioners on a monthly R870 pension.– 1,4 million people on a monthly R870 disability

pension.– Nearly half a million children on the R620 foster-

care grant.– Close to eight million on the R200 child-support

grant.• There are two ways to draw a pie chart for this

information. Do both.

Summative assessment• Ask around either in the class, amongst fellow-learners or at a

business, to find someone who has knowledge of these contracts. • Find out:

– What kind of information is necessary to be accepted as a contracted person?

– Is it possible for a furnishing store to re-possess/take back furniture that you buy under a hire-purchase agreement? Explain.

– If the store does re-possess the bought item, what happens to the installments that you have already paid?

– Which is better for a contracted person: to pay smaller or larger amounts per month?

– What maximum % is a loan-business allowed to charge you?– If you have signed a rental contract for a flat for 24 months and you have

to move out of the area, what can you do to prevent having to continue paying the monthly rental amount?

– Did your friend read the “fine print”? If so, what did it say? If your enquiry is directed to a store, ask them what is in the “fine print”

Activity 10

• The opening page of this account application folder reads: NO FUSS - NO FORMS

• The four back pages of this application enticement are in fine print. And in between these two pages is a five page account application form which you have to fill in.

• Here is just a section of the form. Fill it in.

Activity 11

1.Look at the table for cell phone rates:

Activity 11a. Explain the words “peak” ,”off-peak” and “happy hour”.

b. Is it cheaper to quickly phone (45 seconds) or to send an SMS?

c. During one month you make the following calls: 45 calls from cell phone to cell phone of which 30 are orders placed which last on average two minutes each, and 15 calls from cell phone to land-line. Nine of the latter calls last about 5 minutes (peak time) and the rest take 7 minutes each (off-peak). All of the business calls are in peak time. You also have use happy hour rates for 22 calls to family and friends talking on average 10 minutes. You send about 100 SMS’s during the month. Calculate how much your cell phone cost was during month.

Peak is during the main calling hours; Off peak outside of the main calling time; happy hours will be an hour where the rates are discounted

Assuming per second billing: Off peak: phone 73c SMS 35c; Peak phone R1.35 SMS 0.80

Activity 11

• The Hugenot Tunnel toll gate has the following transport rates:

Activity 11

Each months this company has the following tunnel trips: 23 light vehicles, 19 trucks with two axles, 9 trucks with 3-4 axles and 2 trucks with 5-9 axles.a. Calculate the monthly tunnel expense of this companyb. Yet another toll gate is proposed between the tunnel

and Cape Town with a 15% less charge than the tunnel charges. Calculate the monthly expense of the company if the second toll gate is put into operation. Show your calculations and substantiate your answers.

Activity 11

b. During a very dry month, this same family uses 13 kilolitres of water. Calculate this cost.

c. The Sunshine Plants Nursery uses on average 4545 kilolitres per month. Calculate the cost.

Summative AssessmentThe Business Report of 27th March 2008 writes about the debt trap that is tightening around the poor:The amount that people are paying to service their debt has risen to an all-time high of 80 percent of disposable income, according to figures released earlier this year by the South African Reserve Bank.According to Allister Long, managing director of risk company Powerhouse, as wealthier people are certainly paying less of their disposable income to service their credit cards and other debts, this means that for many others the percentage is over 100 percent.There are some positive signs, however: the cash payment record of some credit retailers has increased from 25/75 (cash/credit) two years ago to 50/50 today.This is a positive sign as it means people are starting to save until they have enough money to pay for an item.The two major reasons for the current squeeze are the increases in interest rates, combined with the implementation of the National Credit Act (NCA).“There is nothing wrong with the Act itself, but because of the potential consequences of being found a ‘reckless lender’ companies have been over-cautious in their process of implementation, while trying to understand the risks of over-lending.“We’re only 12 months into the implementation, and it may take another 6 – 12 months before everything settles down,” says Long.The penalties for being found a ‘reckless lender’ are heavy: in addition to a fine, the lender may be required to write off the loan with no right of legal recourse against the customer.“Much is being done to educate consumers by the signatories to the Financial Sector Charter, but it is a case that there can never be too much. Finmark recently released data that 37 percent of South Africans do not even understand the term “interest rate” – so education needs to commence at an elementary level,” says Long.

Summative Assessment1. Explain the meaning of the information in the first paragraph.2. What does “the percentage is over 100 percent” mean?3. What does this mean: “the cash payment record has increased

from 25/75 to 50/50”?4. Why would the increase in interest rates affect the debt level of

a person?5. Why is it not so easy any longer to obtain credit from a lender?6. Explain with an example the meaning of “interest rate”.7. Explain the difference between a credit card and a debit card. 8. Which of these two cards has an interest rate that is higher and

also negative to the holder of the card?

Summative AssessmentLeonard Dube’s Courier Services..The Sunday Times of 3rd September 2006 reported on the owner of a small company.Leonard Dube worked for 11 years as a driver for an auditing firm in Johannesburg. In 2003 he started a small courier service with one employee (himself), two cars, and a few clients. In 2006 he had five employees and one part-time worker. He owned 6 vehicles, and turnover had grown from R20 000 a month in the first year to about R100 000 a month in 2006.Leonard bought only new vehicles for the company, and had them serviced every three months at a cost of R3000 a car. His vehicles were financed on a hire-purchase basis and his finance payments came to a total of R17000 a month. He spent R4000 a week on petrol. Comprehensive insurance for his vehicles cost R4000 a month. Communication is vital and he bought cellphones for all of his staff members and paid for the airtime, which cost him R5000 a month in 2006.

Summative Assessment

a. What does “monthly turnover” mean – is it gross income or net income?

b. What is the annual turnover of the business?c. Which of Leonard’s listed expenses are fixed and which

are variable?d. List his monthly expenses in 2006 and next to it the

annual expenses for each category of expense.e. If petrol cost R6,50 per litre in 2006, but it costs R10 per

litre in 2008, what will be the increase in Leonard’s monthly petrol cost?

f. Which other expenses might he have in his business?

Summative Assessment• Beverley wants to make a plan to earn some extra money. She

can use her stove for cooking or baking but searches for an energy efficient recipe. She decides to make fudge which takes very little cooking time. She will deliver to local shops. The shop-keeper will take a percentage of the sale cost. She has a foolproof recipe from her granny’s recipe book. The recipe will make about 20 pieces of fudge. She decides to double the recipe.


a. Calculate and complete the two open columns.b. Beverley sells the fudge in single pieces delivered in

a big glass jar to the shops. The individual pieces sell for R2,50 per piece. How much does she make from double the recipe?

c. How much does double the recipe cost her?d. Is it worth her while to continue with the project?e. She wants to make R500 in the first month and

then take it from there. How much fudge will she have to make?
