Using a Calculator
As you prepare for a career in business, the ability to use a financial calculator is essential,
whether you are in the finance division or the marketing department. For most positions,
it will be assumed that you can use a calculator in making computations that at one time
were simply not possible without extensive time and effort. The following examples let us
see what is possible, but they represent only the beginning of using the calculator in finance.
With just a little time and effort, you will be surprised at how much you can do with
the calculator, such as calculating a stock’s beta, or determining the value of a bond on a
specific day given the exact date of maturity, or finding net present values and internal rates
of return, or calculating the standard deviation. The list is almost endless.
In demonstrating how calculators may make our work easier, we must first decide which
calculator to use. The options are numerous and largely depend on personal preference.
We have chosen the Texas Instruments BA II Plus and the Hewlett-Packard 10BII.
We will limit our discussion to the following issues:
I. Introductory Comments
II. An Important Starting Point
III. Calculating Values for:
A. Future value of $1
B. Present value of $1
C. Future value of an annuity of $1 for n periods
D. Present value of an annuity of $1 for n periods
IV. Calculating Present Values
V. Calculating Future Values (compound sum)
VI. Calculating the Number of Payments or Receipts
VII. Calculating the Payment Amount
VIII. Calculating the Interest Rate
IX. Bond Valuation
A. Computing the value of a bond
B. Calculating the yield to maturity of a bond
X. Computing the Net Present Value and Internal Rate of Return
A. Where future cash flows are equal amounts in each period (annuity)
B. Where future cash flows are unequal amounts in each period
I. Introductory Comments
In the examples that follow, you are told (1) which keystrokes to use, (2) the resulting ap-
pearance of the calculator display, and (3) a supporting explanation.
The keystrokes column tells you which keys to press. The keystrokes shown in a white
box tell you to use one of the calculator’s dedicated or “hard” keys. For example, if + /- is
shown in the keystrokes instruction column, press that key on the keyboard of the calcula-
tor. With the Texas Instruments BA II Plus, to use a function printed in a shaded box above
a dedicated key, always press the shaded key 2nd first, then the function key. The HP 10BII
has two shift keys, one purple (PRP) and one orange (ORG). To use the functions printed
in purple (stats) on the keypad, press the purple button first. To use the functions printed
in orange (shift) on the keypad, press the orange button first.

The Time Value of
Money: Future Value
and Present Value
Computations
"If I deposit $10,000 today, how much will I have for a down payment on a house in five years?"
"Will $2,000 saved a year give me enough money when I retire?"
"How much must I save today to have enough for my children's post-secondary education?"
As introduced in Chapter 1 and used to measure financial opportunity costs in other chapters,
the time value of money, more commonly referred to as interest, is the cost of money that is bor-
rowed or lent. Interest can be compared to rent, the cost of using an apartment or other item.
The time value of money is based on the fact that a dollar received today is worth more than a
dollar that will be received one year from today because the dollar received today can be saved
or invested and will be worth more than a dollar a year from today Similarly, a dollar that will
be received one year from today is currently worth less than a dollar today.
The time value of money has two major components: future value and present value. Future
value computations, which are also referred to as compounding, yield the amount to which a
current sum will increase based on a certain interest rate and period of time, Present value,
which is calculated through a process called discounting, is the current value of a future sum
based on a certain interest rate and period of time.
In future value problems, you are given an amount to save or invest and you calculate the
amount that will be available at some future date. With present value problems, you are given the
amount that will be available at some future date and you calculate the current value of that amount
Both future value and present value computations are based on basic interest rate calculations.
FINANCIAL CALCULATORS
Currently, financial calculators, with time value of money functions built in, are widely used to
calculate future value, present values, and annuities, For the following examples, we will use the
Texas Instruments BA II Plus financial calculator, which is recommended by the Canadian
Institute of Financial Planning.
When using the BA II Plus calculator to solve time value of money problems, you will be
working with the TVM keys that include:
CPT — Compute key used to initiate financial calculations once all values are inputted
— Number of periods
— Interest rate per period
— Present value
PMT — Amount of payment, used only for annuities
— Future value
Enter values for PV, PMT, and FV as negative if they represent cash outflows (e.g., investing
a sum of money) or as positive if they represent cash inflows (e.g., receiving the proceeds of an
investment). To convert a positive number to a negative number, enter the number and then
press the +/— key.

Implicitly or explicitly all competing businesses employ a strategy to select a mix
of marketing resources. Formulating such competitive strategies fundamentally
involves recognizing relationships between elements of the marketing mix (e.g.,
price and product quality), as well as assessing competitive and market conditions
(i.e., industry structure in the language of economics).

Enterprise Excellence is Inclusive Excellence.pdfKaiNexus
Enterprise excellence and inclusive excellence are closely linked, and real-world challenges have shown that both are essential to the success of any organization. To achieve enterprise excellence, organizations must focus on improving their operations and processes while creating an inclusive environment that engages everyone. In this interactive session, the facilitator will highlight commonly established business practices and how they limit our ability to engage everyone every day. More importantly, though, participants will likely gain increased awareness of what we can do differently to maximize enterprise excellence through deliberate inclusion.
What is Enterprise Excellence?
Enterprise Excellence is a holistic approach that's aimed at achieving world-class performance across all aspects of the organization.
What might I learn?
A way to engage all in creating Inclusive Excellence. Lessons from the US military and their parallels to the story of Harry Potter. How belt systems and CI teams can destroy inclusive practices. How leadership language invites people to the party. There are three things leaders can do to engage everyone every day: maximizing psychological safety to create environments where folks learn, contribute, and challenge the status quo.
Who might benefit? Anyone and everyone leading folks from the shop floor to top floor.

Grote partijen zijn al een tijdje onderweg met retail media. Ondertussen worden in dit domein ook de kansen zichtbaar voor andere spelers in de markt. Maar met die kansen ontstaan ook vragen: Zelf retail media worden of erop adverteren? In welke fase van de funnel past het en hoe integreer je het in een mediaplan? Wat is nu precies het verschil met marketplaces en Programmatic ads? In dit half uur beslechten we de dilemma's en krijg je antwoorden op wanneer het voor jou tijd is om de volgende stap te zetten.
2. GENERAL INFORMATION
The Texas Instrument BA II Plus financial calculator was designed to support the many possible
applications in the areas of financial analysis and banking.
2
3. The explanations below will make it easier for you to use the calculator.
By default, the calculator operates in financial mode.
The ON/OFF key is used to turn the calculator on and off.
The 2ND key is often used to access financial applications. Press this key when you
want to apply the functions displayed in yellow at the top of the keys.
The FORMAT feature lets you select the number of decimal points to be displayed by the
calculator. If you want to display:
a fixed decimal point, press 2ND and then FORMAT, enter a number from 0 to 8
to specify the number of decimal points, and then press ENTER.
a floating decimal point, press 2ND and then FORMAT, enter the number 9, and
then press ENTER. The number of decimals displayed will vary depending on the
calculations up to a maximum of nine decimals.
To perform the calculator exercises in this document, it is best to use a floating decimal
point format.
Setting the number of payment periods and interest-calculation periods in a financial
calculation (the P/Y and C/Y functions).
P/Y function: this function sets the number of annual payments. The default value
is one payment per year. To change the number of annual payments, press the
2ND and P/Y keys, enter the required value, and then press ENTER (for
example, 12 for 12 monthly payments).
C/Y function: this function sets the number of interest-calculation periods. By
default, the number of interest-calculation periods is the same as the number
entered for the P/Y variable. To change it, press 2ND, P/Y and , and then enter
the number of periods and press ENTER.
Example where the C/Y differs from the P/Y: monthly payments on a personal loan on
which interest is calculated quarterly (I, 4):
Sequence of entries
Display
Explanation
2ND > P/Y > 12 > ENTER
P/Y = 12
Enters a monthly payment
period (12 months).
2ND > P/Y >
ENTER
C/Y = 4
Enters a quarterly interestcalculation period (4 threemonth periods per year).
>4>
N. B.: It is important to follow the sequence of entries without pressing any other key.
3
4. The BGN function lets you activate the beginning-of-period or the end-of-period payment.
To understand the configuration of this function, simply press the 2ND and BGN keys. To
the left of your screen, you will then see the END or BGN letters.
To activate the beginning-of-period payment calculation, simply press the 2ND, BGN,
2ND and SET keys. The BGN indicator then appears in the upper-right area of the
display screen. To return to END, simply repeat the 2ND, BGN, 2ND and SET sequence:
the BGN indicator will disappear.
The CE/C key clears the on-screen data without deleting any numerical values that have
been entered.
The CLR TVM function cancels the numeric values and calculation commands and
resets the calculator’s default financial values. Before performing each calculation, users
are advised to cancel all previously used numerical values by pressing the 2ND and CLR
TVM keys.
These keys, however, do not affect the beginning-of-year payment (BGN) mode or endof-period payment (END) mode or the values attributed to P/Y and C/Y. Therefore, it is
important to make sure that these values have been programmed before performing a
calculation.
4
5. FINANCIAL CALCULATIONS
Most financial calculations are carried out using the following seven keys:
Financial keys
These keys are used to designate or calculate:
N
The number of periods.
I/Y
The nominal interest rate.
PV
The present value of an investment.
FV
The future value of an investment.
PMT
The periodic payment of an amortized loan or a split
annuity.
CPT
Compute key.
BGN
Indicates whether the calculations include the payments
made at the beginning or at the end of each period.
Note:
By convention, the present value of an investment is a negative value. The calculator is
programmed this way; therefore, in calculations of future values or per-period payments, if the
present value is entered as a negative value, the future value or the value of the payments will
be positive. The opposite is also true. It is therefore important to be thorough and refer to the
calculator’s user guide, if necessary.
Sample calculation of the future value (FV) of a single payment
Someone wishes to invest $4,000 in a registered retirement savings plan (RRSP) for a five-year
period.
Insurer A proposes an annual compound interest rate of 6%, whereas insurer B proposes a
nominal rate of 5.95% compounded on a semi-annual basis. The following two tables should
help you determine which insurer is proposing the best investment.

Calculating the future value of an annuity
A client would like to invest $2,500 per year over the next five years. He would like to know what
the cumulative value of the investment would be in five years if the annual realized rate were 5%
in a situation where the investment is made at the beginning of the year and in a situation where
the investment is made at the end of the year.

8. Calculating the payment of a personal or mortgage loan
The process of calculating a personal or mortgage loan consists of:
Determining the known variables;
Entering the number of payment periods (P/Y) and the number of interest-calculation
periods (C/Y);
Calculating the unknown variable.
Sample calculation of a personal loan repayment
Mary wants to borrow $15,000 to purchase a new car, and she wants to repay the loan over a
five-year period. If the bank demands a nominal rate of 6% compounded on a monthly basis,
what would be the monthly repayment (end of period)?
Known variables:
- nominal rate: (6%,12)
- term of the loan: five years (60 monthly payments)
- capital borrowed: $15,000
- Number of annual payments: 12
- Number of interest-calculation periods: 12
The monthly repayment can be calculated using the following operations:

CPT > PMT
PV = − 15,000
PMT = 289.9920229
Enters the amount of the loan.
Calculates the amount of the monthly
payments.
To repay this loan over a five-year period, the monthly repayment amount would be $289.99.

9. Sample calculation of a mortgage loan repayment
Claude buys a home for $125,000 and makes a $40,000 cash downpayment. To finance the
balance, the bank offers him an $85,000 mortgage loan at a nominal rate of 6% compounded on
a semi-annual basis.
What monthly payments will be required to repay this mortgage over a 20-year term?
What will the mortgage balance be after five years?
To answer these two questions, the known variables must first be determined:
- nominal rate: (6%, 2)
