Abstract
The paper presents computations about applications on time value of money, bonds, bonds
valuation and bonds’ interest rates. It is essential for financial managers to have a good
understanding of the concept of time value of money (TMV) and its impact on stock prices.
Companies do not only sustain their operation through assets, but also through debts. Bond is a
form of debt where corporations derive its capital for its operations. Hence, financial managers
also give specific attention to bonds, valuation of bonds and how its interest rates will affect their
financial decision-making. This paper focuses on time value analysis applications like
calculation of present value of uneven cash flow using four different procedures: the step-by-step
approach, the formula approach, using the financial calculator and by use of spreadsheets. The
calculations will show how to do the discounting method to find the present value. Other
applications of the time value concept is also presented here such as the concept of future value,
the effective annual rate, compounding and interest rates. The paper will also present the
calculation of the bond price. It will also provide how the change in market interest rates would
result in a discounted bond and a premium bond. I will also present the calculation of yield to
maturity, the total return, current yield and the capital gains yield a bond. There will be nine (9)
questions presented in this paper, of which I provided solutions on a step-by-step approach.
Keywords: Time value of money, present value, future value, bonds, bond valuation

The Time Value of Money
If you are offered a $1,000 now and a $1,100 in two years, what will you choose? In a
situation where you have extra money to spare for investment what is your decision on accepting
the offer to get money now or in two years. Think you really don’t need the money now, and you
can afford to save for a rainy day. I am going to take the $1,000 and invest in a fixed rate that
grows my money in a certain period, rather than choosing to get the $1,100 offered to me in two
years. This is the concept of time value of money (TVM). For me the time value of money is a
concept where you are going to decide how you will give value to your cash and decide to invest
and get the value of the money over time. In businesses, it is essential for managers – financial
managers, to have a thorough understanding of the time value of money (TVM). A good analysis
and understanding of how money will be valued at a certain future is important in sustaining the
operations of a business.
Another vital information is to get a good grasp of the concept of debts or borrowing.
This paper presents calculations of bond valuations, bond interest rates, and changes of bond
valuation over time. There is a relationship that exist between the market interest rate and the
annual coupon rate of bonds that would result in either discounted bonds or premium bonds
The following nine (9) questions provides scenarios where I calculate solutions by using
the applications of the concept time value of money and bonds.
What is the present value of the following uneven cash flow stream - $50, $100, $75, and
$50 at the end of Years 0 through 3? The appropriate interest rate is 10%, compounded
annually?
This question involves an annuity with uneven cash flow instead of constant payment.
There are two important cases of uneven cash flows: (1) where the cash flow stream consists of a
FIN 534 – THE TIME VALUE OF MONEY 4
series of annuity payments plus an additional final payment, and (2) the uneven or irregular cash
flow stream (Brigham, & Ehrhardt, 2014). This problem is an example of the uneven cash flow
stream. In calculations involving cash flows , payment (PMT) is used in situations where the
cash flow are constant and thus an annuity is involved; if cash flows are different in different
time periods, the term CFt is used which means cash flow in period t.
There are three ways to calculate for the net present value (NPV): (1) the step-by-step, (2)
the use of the financial calculator, and (3) Excel spreadsheet
Variables: I = 10%; CF0 = -$50; CF1 = $100; CF2 = $75; CF3 = $50; N = 3
Cash Flow Stream

The Step-by-Step Method
Periods(N) 0 1 2 3
Cash Flow (CF) ─$ 50.00 $100.00 $ 75.00 $ 50.00
PVs of the CFs ─$ 50.00 $ 90.91 $ 61.98 $ 37.57
PVt of the Irregular CF Stream $ 140.46
Calculation of the above step-by-step method:
PVt = CF0 / (1 + I)0 + CF1 / (1 + I)1 + CF2 / (1 + I)2
+ CF3 / (1 + I)3
PV0 = CF0 / (1 + I)0 = (─ $50) / (1 + 0.10)0 = (─ $50) / (1) = ─$50.00
PV1 = CF1 / (1 + I)1 = ($100) / (1 + 0.10)1 = ($100) / (1.1) = $90.91
PV2 = CF2 / (1 + I)2 = ($75) / (1 + 0.10)2 = ($75) / (1.21) = $61.98
PV3 = CF3 / (1 + I)3 = ($50) / (1 + 0.10)3 = ($50) / (1.331) = $37.57
PVt = $50.00 + $90.91 + $61.98 + $37.57 = $140.46

FIN 534 – THE TIME VALUE OF MONEY 6
The Net Present Value is the present value of the expected future cash flows less the cost
of the investment (Microsoft Excel, n.d.). The NPV function in Excel only calculates the present
value from period 1 to period 3 in this problem. Then we need to subtract the -$50 which is an
outflow (Microsoft Excel, n.d.). The result of the NPV is equal to $140.46.
We sometimes need to find out how long it will take a sum of money (or something else,
such as earnings, population, or prices) to grow to some specified amount. For example, if a
company’s sales are growing at a rate of 20%, how long will it take sales to double? In order
to know how long will it take for a company’s sales to double with the given interest rate of
20%, we need to find the number of years, N. For example the company’s sales is $1,000,000;
the interest rate given here is 20%. How long will it take for the $1,000,000 to double?
In order to find the number of years, N, we can use three procedures: (1) Using the
financial calculator, (2) Excel spreadsheet, (3) by working with natural logs
Variables: FV = $2,000,000; PV = ─ $1,000,000; I = 20%; N=?

NPER 3.8018
In Excel, the NPER function is used to determine the period, N. NPER returns the
number of periods for an investment based on a periodic constant payments and a constant
interest rate. NPER in this example is NPER = NPER(I,PMT,PV,FV). Providing the data
NPER = NPER(0.20,0,-1,000,000,2,000,000) = 3.8018 or 3.8 years.
Method 3: Using the log solution by finding the natural logs using the financial calculator
and solve N (Brigham, & Ehrhardt, 2014).
Interest Rate, I = 20%
Sales = $1,000,000
$2,000,000 = $1,000,000(1+I)N
$2,000,000 = $1,000,000(1 + 0.20)N
$2,000,000 ÷ $1,000,000 = (1 + 0.20)N
2 = (1 + 0.20)N
ln 2 = N[ln(1.20)]
N = ln(2) / ln(1.20)
N = 0.6931471806 / 0.1823215568
N = 3.8018 = 3.80
FIN 534 – THE TIME VALUE OF MONEY 8
Will the future value be larger or smaller if we compound an initial amount more
often than annually ─ for example, every 6 months, or semiannually ─ the stated interest
rate constant? Why? The future value of an investment would be large if the initial amount will
compounded more than annually. There will be higher future values when an initial investment is
compounded more frequently. Interest will be earned on interest more often the more frequent
compounding occurs (Brigham, & Ehrhardt, 2014). The effective annual rate (EAR) also known
as the effective percentage rate (EFF%) will increase due to frequent compounding; hence the
future value and the EFF% will increase as the frequency of the compounding increase
(Brigham, & Ehrhardt, 2014). The biggest increase occurs when compounding goes from annual
to semi-annual (Brigham, & Ehrhardt, 2014).
Comparison of annual compounding and semi-annual compounding:
Variables: PV = $100; Interest rate = 8%; N = 1; M = 2
Compounding: FVN = PV(1 + IPER)Number of Periods = PV(1 + INOM / M)MN
Compounding annually:
FV1 = $100(1 + 0.08 / 1) = $108
Compounding semi-annually:
FV2 = $100(1 + 0.08 / 2)2 = $108.16
What is the effective annual rate (EAR or EFF%) for a nominal rate of 12%,
compounded semi-annually? Compounded quarterly? Compounded monthly? Compounded
daily? The effective (equivalent) annual rate (EAR or EFF%) is the annual (interest once a year)
rate that produces the same final result as compounding at the periodic rate for M times per year
(Brigham, & Ehrhardt, 2014). Given a nominal rate of 12%. The EAR, also known as EFF% is
found from the following equation:
FIN 534 – THE TIME VALUE OF MONEY 9
EAR = EFF% = (1 + IPER )M – 1.0
EAR = EFF% = (1 + INOM / M)M ─ 1.0
Where: INOM is the nominal rate; IPER is the periodic rate; M is the number of periods per
year; N is the number of years and the INOM = 12%
1. Compounded semi-annually:
M = 2
EAR = EFF% = (1 + IPER)M ─ 1.0
EAR = EFF% = (1 + INOM / M)M ─ 1.0
EAR = EFF% = (1 + 0.12 / 2)2 – 1.0
EAR = EFF% = (1 + 0.06)2 ─ 1.0
EAR = EFF% = (1.06)2 ─ 1.0
EAR = EFF% = 1.1236 ─ 1.0
EAR = EFF% = 12.36%
2. Compounded quarterly:
M = 4
EAR = EFF% = (1 + 0.12/4)4 – 1.0
EAR = EFF% = (1 + 0.03)4 – 1.0
EAR = EFF% = (1.03)4 – 1.0
EAR = EFF% = 12.5509%
3. Compounded monthly:
M = 12
EAR = EFF% = (1 + 0.12/12)12 ─ 1.0
EAR = EFF% = (1 + 0.01)12 ─ 1.0
FIN 534 – THE TIME VALUE OF MONEY 10
EAR = EFF% = (1.01)12 ─ 1.0
EAR = EFF% = 1.12682503 ─ 1.0
EAR = EFF% = 12.6825%
4. Compounded daily
M = 365
EAR = EFF% = (1+0.12/365)365 ─ 1.0
EAR = EFF% = (1+0.000327671233)365 ─ 1.0
EAR = EFF% = 1.127475 ─ 1.0
EAR = EFF% = 12.7475%
Suppose the on January 1 you deposit $100 in an account that pays a nominal (or
quoted) interest rate of 11.33463%, with interest added (compounded) daily. How much will you
have in your account on October 1, or 9 months later? To solve this problem we focus on
fractional time periods. Here I assume a 365 days in a year so M = 365
Given: Nominal interest rate = 11.33463%; Period = 9 months or 9/12
1. Computing for the Periodic Rate
IPER = INOM / M = 0.1133463/365 = 0.0003105378082 per day
Computing for the number of days = (9/12)(365) = 273.75 = 274 days
Amount in account on October 1 = $100 (1 + IPER)Number of Periods
= $100(1.0003105378082)274
= $108.8797799
Amount in account on October 1 = $108.88
What would be the value of the bond described below if, just after it had been issued, the
expected inflation rate rose by 3 percentage points, causing investors to require a 13% return?
FIN 534 – THE TIME VALUE OF MONEY 11
Would we now have a discount or a premium bond? A firm issues a 10-year par value bond with
a 10% annual coupon and a required rate of return is 10%.
N = 10; I│YR = 13%; PMT = $1,000(10%)= $100
First I will calculate the bond price on what is originally given which is $1,000.
Input
10.00 10.00 100.00 1000.00
N I│YR PV PMT FV
($1,000.00)
Output
Then calculating using raised interest rate of 13% using the financial calculator returns a
PV = ─$837.21, therefore the bond price is $837.21, which is lower than the original bond price.
Input
10.00 13.00 100.00 1000.00
N I│YR PV PMT FV
($837.21)
Output
This is a discount bond. The coupon rate remains after the issuance of the bond however
the interest rates in the market move up and down (Brigham, & Ehrhardt, 2014). An increase in
the market interest rates (rd) will cause the price of the bond to fall (Brigham, & Ehrhardt, 2014).
This bond is a discount bond as this fixed-rate bond’s price fell below its par value due to the
increased market interest rate over the annual coupon rate.
What would happen to the bond’s value if inflation fell and rd declined to 7%? Would we
now have a premium or a discount bond? In the same situation, that a firm issues a 10-year,
$1,000 par value bond with a 10% annual coupon and a required rate of return is 10%. So the
original bond price is $1,000.
First calculating for the bond price at the given 10% interest rate.

Then computing for the bond price with a rd = 7%
Input
10.00 7 100.00 1000.00
N I│YR PV PMT FV
($1,210.71)
Output
The bond price is $1,210.71 which is above the original bond price. Bond prices rise
when the market interest falls or when rd falls. When a going interest rate falls below the coupon
rate, a fixed-rate bond’s price will rise above its par value and it is called a premium bond
(Brigham, & Ehrhardt, 2014). This bond that has a 7% market interest rate returns a bond price
of $1,210.71 is a premium bond.
What is the yield to maturity on a 10-year, 9% annual coupon, $1,000 par value bond
that sells for $887.00? That sells for $1,134.20? What does a bond selling at a discount or a
premium tell you about the relationship between rd and the bond’s coupon rate? In this problem
the given for the described bond is N=10 years, Coupon rate = 9%, Par Value = $1,000, Bond
Price = $887.00. The yield to maturity (YTM) is the same as the market rate of interest, rd .
To solve for the yield to maturity (YTM) for the bond price of $887.00, using the
financial calculator, I entered all the required values in the financial calculator to solve the yield
to maturity (YTM)

The yield to maturity (YTM) is 10.91%
To solve for the yield to maturity (YTM) for the bond price of $1,134.20, using the
financial calculator:
Input
10 ($1,134.20) 90.00 1000.00
N I│YR PV PMT FV
7.08
Output
The yield to maturity (YTM) is 7.08%
A bond selling at a discount means that the rate of interest (rd) is above the bond’s coupon
rate that would result in the bond’s fixed-rate price falling below the par value. While a bond
selling at a premium means that the rate of interest (rd) falls below the bond’s coupon rate, as a
result the fixed-rate’s bond price will rise above its par value. When rd goes up above the coupon
rate the bond price goes down below the par value, and when rd goes down, below the bond’s
coupon rate, the bond price goes up above the par value. Whenever the rd equals the coupon rate,
a fixed-rate bond will sell at its par value.
What are the total return, the current yield, and the capital gains yield for the discount
bond in the previous question #8 at $887.00? At $1,134.20 (Assume the bond is held to maturity
and the company does not default on the bond). The bond described in this problem is a 10-year,
9% annual coupon, $1,000 par value bond. As I stated before when rd rose above the coupon rate,
FIN 534 – THE TIME VALUE OF MONEY 14
the bond would sell below the par value hence the bond will sell at a discount, this bond is called
the discount bond. The discount bond price of $887.00 is a result of the rise of the rd to 10.91%.
Using this bond price , I will compute the total return, the current yield, and the capital gains for
this discount bond from Year 2(with N=9 years) and Year 1 (with N=10 years).
The question did not specify as to what year or what period the total return, current yield,
and the capital gains be calculated, I will provide two periods. First I will calculate for the
required data for year 2 and then I will calculate at the maturity date which is the year 10, where
N = 0. This is assuming the bond is held to maturity and company does not default on the bond.
This calculation will hold through for the discount bond and the premium bond.
