Compound Interest calculation
Most of the banks and person dealing with funds use the word compounding interest annually,semi-annually or quarterly etc. to understand better compound interest would meancalculating the interest on interest also. The mathematical formula shall be as follow:
C.I. = P , where C.I. = compound interest
If the interest rates for the successive fixed periods are r1%, r2%, r3% ..., then A
(amount) is given by
A=P ... .., where A= amount & principal , P= principal
For example continue with the same example in previous sheet. If the period is 3 years thenCI would be
C.I. =5000 x {(1+ .09)-1} = 1475.145A =5000 + 1475.145 = 6475.145
Press CMPD key
Input the following using scroll and exe keys
* Use of option PMT is explained in next page
Note: Using scroll key please enter the P/Y = 1 and C/Y = 1 as the same represents the
Installments per year and Compounding per year respectively. If the compounding issemi annually then C/Y should be selected as 2 and for quarterly the same should be
selected as 4.
Note: Press ESC key to come back to previous screen
Note: To clear variables from the memory is to press SHIFT key and 9 key and EXEkey and chose the correct option to clear either setup, memory or allvariables from the memory

EMI calculation CMPD continues.
A very important tool for finance companies having the business of lending money and all
those also borrowing money and in the need to know that how much monthly installment needto be paid for a particular loan.
Typically a person needs to know the present value of amount borrowed/lend and the interest
rate to be paid also the total number of installments to be used while returning the amountborrowed. i.e.
PV = amount borrowed or lend i.e. INR 50000
I% = interest rate i.e. 12% p.a. i= I%/12/100 = 0.010N = number of installments per year i.e. 15 years = 180 times
A typical way of calculating the EMI shall be taking the help of computer or a long sheet of
paper and lot of time in computing and yet not very sure about the way of doing. The formulashall be as follows:
PV x i x (1+ i)
=(1+ i)-1
= 50000 x 0.01 x (1.01)180
(1.01)180
- 1
= 600.08
EMI calculation without a calculator having the solving power like this is just impossible anddoing little simulations and variations in interest, principal etc, the working becomes verytough, but the use of FC 200V is very simple, faster and economical, lets see
Press CMPD key and using the scroll and exe key enter the following data

Scroll back to PMT key and enter solve key as the answer flashes -600.08.
Is it not quite amazing the result is produced in less than a minute as against probably one
hour?
Now we can use variation just like mortgage calculators available on the web and computerspreadsheets e.g.
1. Calculate the PV if we know how much maximum EMI can be paid
2. Calculate the maximum Rate of interest can be borne if EMI, period and PV is
known
3. Calculate the Number of periods (i.e years) wherein loan can be repaid if PV, I%and EMI is known
Just in simple way skip the term we want to know and enter the data in rest of the terms as
before, using the scroll key come back to the term we want to know and press solve key andresult is available.

Explanation
Example
Cash Flow Calculation
The application mainly is used by analysis to appraise an investment proposal having a fixed
stream of cash inflow after a fixed period of cash outflow. Typically an investor need to knowthe following to do the analysis i.e. cash outflow and cash inflow and certain financial tools to
help him to take the decision, the tools could be Internal Rate of Return (IRR), Net PresentValue (NPV), Net Future Value (NFV) and Payback Period (PBP)
PBP The payback period is defined as the number of years required to recover a projects
cost.
NPV The net present value (NPV) method discounts all cash flows at the projects cost ofcapital and then sums those cash flows.
Accept project if NPV > 0.
IRR The internal rate of return (IRR) is defined as the discount rate which forces a
projects NPV to equal to zero.
Accept project if IRR > cost of capital.
A typical cash flow shall work out as follows
Cash Inflow
Cash Outflow
An investment would outlay an expenditure of INR 100000 in the year0 and thereafter for thenext four years it generates the cash inflow at a consistent flow of 40000 per year.
The PBP shall work out to be like 100000/40000=2.50 years
-

The NPV shall be as follows:
Particulars cash In/Out Discounted Cash Flow @12%
Year 0 -100000 -100000 -100000.00
Year 1 40000 40000/ (1.12) 35714.28
Year 2 40000 40000/ (1.12) 31887.75
Year 3 40000 40000/ (1.12) 28471.21
Year 4 40000 40000/ (1.12) 25420.72
Net present value +21493.96As you know, money devalues over time. The rate at which it does is commonly referred to as
the "discount rate". Therefore, let's say you have a payment/income profile as shown aboveand we assume a discount rate of 12%. If you take the difference between the net present
value of the payments and the net present value of the returns, you get the net present valueof the investment. In the case shown above that turns out to be 121493.96-
100000=21493.96. (NPV)
IRR
If we equate the net present value to zero we get the internal rate of return, a rate which putscash outflow-discounted cash inflow equal to zero, the significance of IRR is that for example
the IRR for the above said case is 21.86% and if the money devalues at 22% then you makenothing on your investment. So prudence say that you must make investment that fetches
you return greater than 22%.
The IRR can be derived only be trial and error method and a guessed cost of capital should beestimated otherwise the trial and error method also takes long time and is irritating.
The common method used for IRR is
CF+ CF +CF +CF +CF = 0
(1+r) (1+r) (1+r) (1+r)
In the given case if we discount the cash flow by an estimated rate of capital of 21% shallgive us the NPV equal to +1617.64Again using the trial method we forward the rate to 22% and see the NPV coming out to beas -254.38 but the object is to bring the discounted cost of capital equal to Zero so by usingthe trial and error method we use the following
Formula
1617.6421% + ----------------- X 1
1617.64+254.38
= 21.86% (IRR)
We have seen how cumbersome procedure is used to calculate the IRR and NPV imagine aperson evaluating the 50-100 proposals a day shall get mad and crazy. The solution providedby FC 200 V is quite simple and we just have to input the data as follows:

Interest rate conversion calculations
The conversion of annual interest rate into effective interest rate is usually used when thecompounding per year is more than one. The conventional way of calculating EEF (effectiveinterest rate) is:
EEF = 1+APR/100
n- 1 x 100 APR Annual percentage rate (%)
n EEF Effective interest rate (%)N number of compounding
APR = 1+EEF/100 1/n
- 1 x n x 100
n
Example of converting the annual rate is where an investor gets the return on an investmentother than annual basis then his first curiosity shall be to know what my effective annualinterest rate is. E.g.
Interest rate: 12% compounded semi annually, the EEF shall be 12.36% and if the EEF is 14%then APR shall be 13.54%. Similarly if the compounding can be quarterly (4) or monthly (12)and accordingly results can be obtained but how complex is to solve the power of 12.
Press CNVR key
Input the above data using scroll and exe key
Other way could be press i% =14 and press APR key the result shall be 13.54% as describedabove.
N = Press 2 and enter Exe key
I% = Press 12 and enter exe key
EEF = press solve key and the result is 12.36%

Cost / selling price / margin calculations
Cost and their relation with the selling price is very well known, the difference is known asmargin which could be profit or loss. The formula for calculation shall be as follows:
CST = SEL * (1-MRG/100)CST= costSEL= selling priceMRG=margin
SEL = CST/ (1-MRG/100)
MRG = (1- (CST/SEL))*100
Select COST Key
By inputting any two values the third value can be calculated, by using the following way, itcan be done:
Note: By inputting any two variables thirdvariable can be calculated, typicallymargin is the selling price less cost
and divided by selling price as the%age of sale price, conversely many
people use the cost as the base price for generating the %age of value addition to thecost.
CST = Press 1200 and enter exe key
SEL = Press 1500 and enter exe key
MRG= press solve key answer shall be 20%

Amortization calculations
Amortization means "the systemic payment plan -- such as a monthly payment -- so that your
loan is paid off over the specified loan period."
So an amortized loan is for one specific amount that is to be paid off by a certain date, usually
in equal monthly installments. Your car loan and home loan fit that definition. Your credit card
account doesn't because it's a revolving loan with no fixed payoff date.
A part of the payment goes toward the interest cost and the remainder of the payment goes
toward the principal amount -- the amount borrowed,"
Interest is computed on the current amount owed "and thus will become progressively smalleras the ending balance of the loan reduces."
In simple meaning when you borrow money the first repayment of loan installment, theinterest is on the full amount of loan but as you continue to pay back the principal amountkeeps on reducing so is the interest amount.
But if you want to know the breakup of any EMI or installment into Principal and Interest it
shall be a quite difficult task for common man.
Let us understand the concept of amortization in simple amortization calculator. The concept
of PMT, interest, FV, BAL, INT, PRN, INT, PRN ETC can be understood with an easy
example.
In the given case the PV = 10000 and interest rate is 2% and the PMT working out to be286.43 over a period of 3 years i.e. N=36 months, please note the Amortization table helpsyou to calculate the interest and principal on any of the installment specified. The requirement
is to know the PMT = EMI = -286.43 (remember EMI can be calculated by CMPD key),PV=principal = 10000 and Interest = i%=2. You can calculate between any month to any
month i.e. PM1 to PM2, remember that PM2 needs to be greater than PM1.

Depreciation calculation
With the help of FC200 we can calculate the following four popular method ofcalculating the depreciation on fixed assets:
Depreciation means wear and tear of the assets due to its usage.
Straight Line Method (SL)Fixed Percentage Method (FP)Sum of Years Digit Method (SYD)Declining Method or written Down Value Method (WDV)
Straight Line Method= (P-S)/n P= Principal Value
S=Salvage value if anyN=Number of years
Fixed Percentage Method = (P-S) x FP P= Principal Value
S=Salvage value if anyN=Number of years
Sum of years Digit Method
First Year = N (P-S)Sum-of years
Second Year = N-1 (P-S)
Sum-of years
Third Year = N-2 (P-S)Sum-of years
.
.
Last Year = 1 (P-S)
Sum-of years
For our exam le N=5 and the sum of ears is 1+2+3+4+5=15
Declining method or WDV
Depreciation in First year = (P) x Depreciation rate
Second year and onwards= (Net book value) x Depreciation rate
Net book Value = (P-S-Accumulated depreciation)

Break even point analysis
This is a very common term used often by Finance Manager or Production Manager, apoint of sales or a point of quantities to sell where the company would break even orto ore specifically company would neither gain nor lose. The profit at such sales wouldbecome Nil or 0%.
This tool is very important for Managers as it suggest that company to break evenmust sell at least N number of quantities.
Lets see the calculation of Break even (quantities)
Break even (quantities)=Fixed Cost / (Selling Price(Unit)
Variable Cost(Unit)
)
Break Even (Values) = Break even (quantities) x Selling price (Unit)
For calculating the BE we need selling price per unit (PRC), variable cost per unit
(VCU), Fixed Cost (FC)
Using the FC200V
Press BEVN key and using the scroll key enter the following values
Press exe key at BEV and input the following Hypothetical data

Using Exe key enter following
*In case the company wants to know how much quantities need to be sold for
achieving the profit (PRF) of say 10000, then after selecting PRF above enter the PRF /
r% as 10000 and then QBE and SBE can be calculated for a profit target of 10000
* the option can be used if company wants to know that how much quantities need to
be sold for achieving the profit % of say 10%, then after selecting r% above enter the
PRF / r% as 10 and then QBE and SBE can be calculated for a profit target of 10%.
Margin of Safety (MOS)
Margin of safety denotes that how much sales can be dropped before attaining the
losses. For example if sales are 120000 and SBE is 48000 then MOS shall be 0.60.
That denotes that sales from the present levels can be dropped by 60% before
company starts incurring losses.
Continuing from the last hypothetical figures where the SBE was 48000 and suppose
the actual sales are 120000 that means the actual sales are more than the Break even
sales of 48000. I.e. Margin of safety is 60%
By inputting any two values
third value can be calculated
DEGREE OF OPERATING LEVERAGE (DOL)
The extent to which a business uses fixed costs (compared to variable costs) in its
operations is referred to as "operating leverage." The greater the use of operatingleverage (fixed costs, often associated with fixed assets), the larger the increase inprofits as sales rise and the larger the increase in loss as sales fall.

= Sales less Variable cost / sales less total cost
Degree of operating
leverage can be calculated if
we know the total sales, total
variable cost and the total
fixed cost.
DEGREE OF FINANCIAL LEVERAGE (DFL)
The degree of financial leverage (DFL) is defined as the percentage change inearnings per share [EPS] that results from a given percentage change in earningsbefore interest and taxes (EBIT), and is calculated as follows:
DFL = Percentage change in EPS divided by Percentage change in EBIT
This calculation produces an index number which if, for example, is 1.43, means that a
100 percent increase in EBIT would result in a 143 percent increase in earnings pershare
In simple terms the DFL means the impact of Interest expenses on the earnings of the
company
DEGREE OF COMBINED
LEVERAGE (DCL)
Combined leverage is the product of operating leverage and financial leverage.That is: DTL=DOL*DFLWhere: DTL=degree of total leverage.DOL=degree of operating leverage.
DFL=degree of financial leverage.
Application of total leverage
1. Degree of total leverage measures the percentage change in EPS that results from
a change in one percent in output.

Statistical analysis
Before understanding the concept of Standard deviation, we must understand the
term Mean and Variance
Mean as a common meaning denotes the center and arithmetically represents the
average of the given population or sample data
Variance is a parameter that measures how dispersed a random variables probability
distribution is. For two random variables the one on the left is more dispersed than the
one on the right. It has a higher variance. In more common terminology we can say
that it measures the variability from the mean.
Variance can be of two types:
Population variance
Sample Variance
High vs. Low Variance
Example of Population variance
The population variance is the mean squared deviation from the population mean:
Here is an example of the variance formula in action.

Example of Sample variance
In practice population variance cannot be computed directly because the entire population
is not ordinarily observed. An analogous measure of variability may be determined with
sample data. This referred to as sample variance
Sample variance can be calculated in the similar way as Population variance except thatthe divisional factor is one number less than the total numbers i.e N
S2
=Sample variance =
X = Sample mean data
Standard Deviation
The standard deviation is the positive square root of the variance:
Population standard deviation:
Sample standard deviation:

Bond (Annualized Yield or Yield to Maturity)
The customary way of calculating the yield on Bonds purchased from the market is to typically
finding the Internal Rate of Return (IRR)
To understand Bond we must understand the complete terminology of the Bonds, e.g.
Coupon Rate = CPN = rate of interest payable on the face value of the Bonds
Purchase price = PRC = Price at which these bonds are available in the market
Redemption value = RDV = Price at which maturity value is paid back to bondholders
Term = n = Period of the bond, it can be either Fixed or can be derived from two dates
Yield = YLD = the effective rate of interest or YTM.
Example
A bond sold in the market at discount of 5% (face value-100, coupon rate-4%) and has a termperiod of 5 years. Find out its effective return?
An investor to this Bond shall enjoy following benefits
Period Cash flow
Year 0 -95
Year 1 04Year 2 04
Year 3 04Year 4 04
Year 5 104* (*Investor would get the Principal amount also in addition to Interest)
Equate the present value of all Cash flows to Zero and using the trial and error method findout its Yield, using a discount factor of 5%, we get following
CF0(5%, 1st year)+CF1(5%, 2nd Year)+CF2(5%, 3rd Year)+CF3(5%, 4th year)+CF5(5%, 5th Year)=0
= (-95*0.9523)+(4*0.90702)+(4*0.86384)+(4*0.82270)+(104*0.78353)
=1.39
Similarly using the Discount factor at 5.25% we get the net present value as -0.374649
To be more precise the YTM shall be 5.16% where the discounted cash flows shall be nearlyequal to Zero.

Operation: Press BOND key and using scroll and exe key enter the following data:
The interest option can be selected either Annual or Semi annual and also the
period of bond can be either fixed or term Fixed period bonds shall give the option of putting two different dates as
purchase date and maturity date Term period bond give the option of only putting the number of years as the
life of the bond
If the Coupon rate is 4% and the Redemption price if 100 and to get the Yield of 8% what
should be the purchase price of the bond in the market?
The purchase price shall be 84.03 in the market to get the yield of 8% in the bond the Interest
accrued on such bond shall be zero and the purchase price including interest shall be 84.03only
