    PART A


    Interest definition means that the cost of borrowing money or fee paid on

    borrowed asets. Interest is the price that you need to pay because you are

    borrowed money or, money earned by deposited funds.An interest rate is the

    cost stated as a percent of the amount borrowed per period of time, usually one

    year and one month. The aim of interest is to bear the risk of currency collapse in

    the future. Beside that, it is to bear loss towards lender because postponing loan.

    The lender or bank will increase the interest because the possibility the the value

    of money might be in increase during the term of the loan. If they not increase the

    interest the lender will loss.

    For example :

    When you take a loan out from a bank, or wherever, they will expect you to pay

    interest. This means that you pay back what you took out on a loan, plus extra

    money. So for example, if you took a loan out for RM500, and let's say you have

    to pay it back with 15% interest, you would pay back RM575.

    The ability to calculate interest is a vital part of understanding how well

    you are managing your finances. Not only is interest likely a major player in

    whatever debt you may owe, but it can also be a key factor in making your

    money grow.

    1. Take a RM10,000 loan from your banking institution for 1 year and assume you

    have to pay RM100 interest for one year, with a stated interest rate of 5%.

    2. Calculate the effective loan rate = Interest divided by Principal or

    RM100/RM10,000 = 5%.Your APR annual percentage rate is equal to the

    previous stated rate.

    3. Currently personal lines of credit loans and home mortgage loans will range from

    the low 5% to the high 12-15% interest. Typically lines of credit will require a co-

    signer and home loans often need at least 10-20% down to make the deal work.

    4. Right now is a tough time to get a loan at a bank but if you have collateral such

    as other properties to leverage or a car that is newer than 10 years you can use

    them to borrow more money. Life insurance, stocks, bonds, and other

    investments are also subject to be used as collateral.

    Simple interest is calculated on the original principal only. Simple interest

    is normally used for a single period of less than a year, such as 30 or 60 days.

    The simple interest can calculate according to the following formula:

    Formula to find simple interest:

    Simple Interest = p x i x n


    Interest = the total amount of interest paid,

    Principal (p) = the amount lent or borrowed,

    Rate (i) = the percentage of the principal charged as interest each

    year. The rate is expressed as a decimal fraction, so

    percentages must be divided by 100. For example, if the

    rate is 15%, then use 15/100 or 0.15 in the formula.

    Time (n) = is the time in years of the loan.

    or you can use the second formula :

    = Amount in Ringgit Malaysia X interest rate % X time ( in year,month ) = total

    For example:

    Saiful borrowed RM 20,000 from the bank to purchase a car. He agreed to repay

    the amount in 10 months, plus simple interest at an interest rate of 10% per year.

    If shaida repay the full amount of RM 20,000 in eight months, the interest would

    be :


    Amount in RM X interest rate X time

    = RM 20,000 X 10% X 10 month

    = RM 1666.67

    If he repays the amount of RM 20,000 in fifteen months, the only change is with

    time. Therefore, his interest would be:


    = RM 20,000 X 10% X 15 month

    = RM 2500.00

    Example 2 :

    If RM 5000 is invesed for 2 years at an annual interest rate of 10%, how much

    interest will be received at the end of the 2 year period?


    I = RM 5000(0.10)(2) = RM 1000


  • 7/27/2019 0. Overall 2zz


    S = RM 5000 + RM 1000 = RM 6000

    Three other variations of this formula are used to find P, R and T:

    P = I R = I T = IRT PT PR

    Simple interest problems can involve lending or borrowing. In both cases

    the same formulas are used.

    Whenever money is borrowed, the total amount to be paid back equals the

    principal borrowed plus the interest charge:

    total repayments = ( principal + interest )

    Usually the money is paid back in regular instalments, either monthly or weekly.

    To calculate the regular payment amount, you divide the total amount to be

    repaid by the number of months ( or weeks ) of the loan. Like this:

    monthly payment amount = principal + interest

    loan period,T,in months


    weekly payment amount = principal + interest

    loan period,T,in weeks

    To convert the loan period, 'T', from years to months, you multiply it by 12, since

    there are 12 months in a year. Or, to convert 'T' to weeks, you multiply by 52,

    because there are 52 weeks in a year.

    The example problem below shows you how to use these formulas:


    A student purchases a computer by obtaining a simple interest loan. The

    computer costs RM1500, and the interest rate on the loan is 12%. If the loan is to

    be paid back in weekly instalments over 2 years, calculate :

    1. The amount of interest paid over the 2 years,

    2. the total amount to be paid back,

    3. the weekly payment amount.

    Given: principal: 'P' = RM1500, interest rate: 'R' = 12% = 0.12,

    repayment time :

    'T' = 2 years

    Part 1: Find the amount ofinterest paid.

    interest: 'I' = PRT

    = 1500 0.12 2

    = RM360

    Part 2: Find the total amount to be paid back.

    total repayments = principal + interest

    = RM1500 + RM360

    = RM1860

    Part 3: Calculate the weekly payment amount

    A second method that you can paying interest is the compound interest method.

    Compound interest means where the interest for each period is added to to the

    principal before interest is calculated for the next period. Its means this principal

    will grow as the interest is added to it. This method is used in investment such as

    saving accounts.

    Formula :

    interest year 1 = p x i x n = 10,000 x .05 x 1 = 500

    interest year 2 = (p2 = p1 + i1) x i x n = (10,000 + 500) x .05 x 1 = 525

    interest year 3 = (p3 = p2 + i2) x i x n = (10,500 + 525) x.05 x 1 = 551.25

    Faizah want to buy a car. She borrowed RM 30,000 in 3 years at 5% annual

    interest compounded annually:

    The principal for the first year is RM 30,000.

    The interest at end of the first year is

    I= RM 30,000(0.05)(I) = RM 1500

    The amount at the end of the first year is

    S = P + I= RM 30,000 + RM 1500 = RM 31,500

    The principal for the second year is RM 31,500.

    The interest at the end of the second year is

    I= RM 31,500(0.05)(1) = RM 1575

    The amount at the end of the second year is

    S = P + I= RM 31,500 + RM 1575 = RM 33,075

    The principal for the third year is RM 33,075

    The interest at the end of the third year is

    I= RM 33,075(0.05)(1) = RM 1653.75

    The amount at the end of the end year is

    S= P + I= RM 33,075 + RM 1653.75 = RM 34,728.75

    S = P(1 + I )n.

    If RM 5000 is invested for 5 years at 9%, compunded annually, how much

    interest is earned?


    S = P (1 + I ) n

    S = RM 5000(1 + 0.09)5

    = RM 5000(1.5386)

    Additional Information

    Try to keep the interest you pay to a minimum. Your money will grow

    faster if you pay little to nothing in interest compared to what you receive in

    interest or appreciation of investments. This means paying off debts before you

    worry about investing, because your creditors are likely going to charge a higher

    interest rate than the interest rate any investment will pay out (with the possible

    exception of low-interest mortgages and student loans). When you have debt, it

    really is better to give than receive.

    Keep in mind that when interest is compounded, it is often broken up

    into smaller amounts. For example, a 12 percent annual rate that is compounded

    monthly would result in 1 percent being compounded 12 times, which makes for

    12.68 percent interest over a year. You can see for yourself if you follow the



  • 7/27/2019 0. Overall 2zz


    Calculation of All Type of Interests.

    1. Know what the entire amount drawing interest is. This is the principal. For this

    example, let's say the principal is RM10,000.

    2. Decide if you want to calculate simple interest or compound interest. Simple

    interest is a one-time charge. Compound interest builds on itself from one period

    to the next. It could be compounded yearly, monthly or even daily.

    3. To calculate simple interest, take the interest rate and divide by 100. If your

    interest rate is 7 percent, this would turn it into .07. Now multiply that decimal by the

    amount of the principal (which is RM10,000 in our example) to get the interest. In

    this case, it would be RM700.

    4. Calculating compound interest is more complicated. Suppose your 7 percent

    interest is compounded every year, and it is for an investment, not a debt. That

    means RM10,000 turns into RM10,700 after one year. The following year you would

    earn interest of .07 multiplied by RM10,700, which equals RM749. Now the total

    comes to RM11,449.

    5. If you need to calculate compound interest over more than just a few periods

    of time, it is easier to use a formula instead of repeating a calculation over and over.


  • 7/27/2019 0. Overall 2zz


    To do this, first add a 1 to your interest rate decimal. Therefore a 7 percent rate

    would become 1.07.

    6. Then convert this number to the power of your number of times the interest is

    compounded. If it is once a year for 12 years, then it would be 1.07 to the 12th

    power, which equals 2.25. That means your money will have grown 2.25 times at the

    end of 12 years.

    From these calculations, BSN bank offers lowest interest rates.So,we

    choose BSN bank as the bank preferred to make loans.

    Income Expenditure = Balance

    RM 580 RM539 = RM41

    We use the RM539 monthly for expenditure, including banks for repayment of

    RM159 per month.We have a balance of RM41.This balanced can be used to

    purchase computer accessories.

    Bank repayment

    We need to pay RM159 to the bank for a month.The interest for this loan is

    4.75%.We choose to pay for the next three years (36 month).RM 159.00 x 36 (month) = RM 5724.00. (repayment for 3 years)

    RM 5 724.00 (bank repayment for 3 years) x 100 = 27.41%

    RM 20 880.00 (income for 3 years)

    From these calculations, we have used a total of 27.41% of our

    income for the next three years for repayment of bank. So, the use ofmoney to pay bank is not too heavy as us as a student.

    of my classmates had to find and gather information at the Al-Khindi Library in

    evening.Many information that we collected from the books in the library.Inaddition, we also exchange information obtained to facilitate our work.With

    modern technology facilities, I can find information more quickly.

    arrange a schedule to do this can be done at the appropriate time for us besides

    we had to attend the lecture-course change in the afternoon and evening in

    addition to compulsory courses in the morning.Alhamdulillah, in accordance withthe timetable, this task can be made more lancar.We also have a discussion with

    other friends about this tasks.We had exchanged of views and information that

    information obtained and we more understand about this assignment.Thank youto the bank officials Mr. Rashidi bin Ishak, Mr. Syed Nasrul Hakim bin Syed

    Idross and Mr. Saifuddin bin Yusuf.Without information from them,probably thisassignment cant be done better than before.In addition, we also met with Mrs.

    Amalina to discuss about the draft before we start our typing tasks.She had

    assisted us in correcting our draft and giving evidence more about this work


    After completing this course, I can understand more about the interest rate

    charged by the bank when we want to make loans bank.Besides, I can make

    more accurate choices when choosing banks want to make a loan. The result of

    this knowledge, I can to apply to my daily life and in the future later.



    The assignment was given on 17th August 2010 and should be submitted

    to our lecturer on 3rd September 2010. Soon after I went through the task given, I

    found that the assignment given were quite challenging. Therefore, I need to do

    my best to finish this assignment although this is my first assignment.

    Nevertheless, these first assignments are quite difficult and sometimes make me

    feel nervous about it.

    During the preparations to do this assignment, I went through a lot of

    difficulty. First at all, I couldnt get enough information regarding the task given. I

    tried to surf the internet but sometimes the connection failed me. The most

    important obstacles are I did not really understand what the requirements of the

    assignment are.

    In this IPG, I found that the library did not have enough references

    regarding this assignment. Although the library was big enough and has a lot

    books, it has limited reference especially a mathematic books. To overcome this

    situation, my friends and I went out to the town to get further information. The first

    destinations were CIMB Bank. We managed to meet Mr. Abdullah and he

    explained to us about compound and simple interest. He also thought us the

    interest calculation processes and suggested the most suitable interest rates

    should be taken.

    Soon before we leave the premises, Mr. Abdullah gave us several

    pamphlets as a reference to get further understanding about interest. Then, we

    went to BSN Bank to get seek other information about interest, particularly from

    BSN Bank.

    Besides that, Im also tried to get the other information from internet.

    Unfortunately, I did not get any Wi-Fi connection and I had to borrow broadband

    Wi-Fi from my friends. At the same time, my understanding to the question given

    was still not satisfying. Finally, with the assistant from my lectures and my

    friends, I really understand the requirement of the question and the assignment

    given. Although the assignment were challenging to me, in the process my

    English skill and knowledge was increased e.g. the writing and reading skill. It is

    because the assignment needs to be prepared in English.

    Furthermore, during the process to finish this assignment, Im found that my

    relationship between my friends were tightens and also our espirit de corps. We

    always discussed and gave our opinion to get some ideas to finish this


    The assignment also taught me to manage my personal expenditure. The

    assignment taught me not to spending money to unnecessary items. It is

    because since I further my study at this IPG, I did not manage my money


    Finally, my first assignment has taught me and give me experienced really

    benefit to me. Ill be using the experience and knowledge to fulfill my ambition to

    become a successful teacher from this IPG.
