Microsoft Excel 2016 Functions
Formula:
A formula is a sequence of values, cell references,
names, functions, or operators in a cell that together
produce a new value. Formulas are equations that
perform calculations on values in your worksheet. A
formula always starts with an equal sign (=).
You can create a simple formula by using constants
and calculation operators.
Function:
A function is a prewritten formula that takes a value
or values, performs an operation, and returns a value
or values. Use functions to simplify and shorten
formulas on a worksheet, especially those that
perform lengthy or complex calculations. A function
starts with an equal sign (=).

Terms
Cell references:
You can refer to data in worksheet cells by including
cell references in the formula. For example, the cell
reference A2 returns the value of that cell or uses that
value in the calculation.
Constants:
Constants are entries that have a specific fixed
value.
Range:
A range is a group or block of cells in a worksheet
that have been selected or highlighted (A1:A10)

Contd…
Arguments:
Most Excel functions are designed to accept data that it
then uses in its calculations. This data is referred to as
arguments and go between the round brackets that follow
the functions name. the IF function, for example, has three
distinct arguments: The logic test, the value if true, the value
if false and the =IF (logic test, value if true, value if false)
Array:
An array is range or group of related data values. In a
spreadsheet program such as Excel the values in an array
are normally stored in adjacent cells.
There are two types of array in Excel:
 One-dimensional array: Where the data is located in single column or
row.
 Two-dimensional array: where the data is located in multiple columns
or rows.

Operators:
Operators:
Operators are the symbols that are used to specify the
type of calculation that you want the formula to perform.
For example, the ^ (caret) operator raises a number to a
power, and the * (asterisk) operator multiplies numbers.
Types of operators:
There are four different types of calculation operators:
arithmetic, comparison, text concatenation, and reference.
Arithmetic operators:
To perform basic mathematical operations such as
addition, subtraction, or multiplication; combine numbers;
and produce numeric results, use the following arithmetic
operators.

Contd…
Arithmetic Operator Meaning Example
+ (Plus Sign) Addition 2+2
- (Minus Sign) Subtraction-Negation 3-2
* (Asterisk) Multiplication 2*4
/ (Forward Slash) Division 6/2
% (Percent Sign) Percent 10%
^ (Caret( Exponentiation 4^2

Contd…
Comparison operators:
You can compare two values with the following operators.
When two values are compared by using these operators,
the result is a logical value either TRUE or FALSE.
Arithmetic Operator Meaning Example
= (Equal Sign) Equal To 2=2
> (Greater Than Sign) Greater Than 3>2
< (Less Than Sign) Less Than 2<4
>= (Greater Than or Equal To Sign) Greater Than or Eql to 6>=2
<= (Less Than or Equal To Sign) Less Than or Eql to 2<=6
<> Not Equal To Sign Not Equal To 4<>2

Contd…
Text Operator Meaning Example
& (Ampersand) Connects, or
concatenates, two
values to produce on
continuous text value.
(A1 & A2)
Text Concatenation operator:
Use the ampersand (&) to join, or concatenate, one or
more text strings to produce a single piece of text.

Contd…
Reference operators:
Combine ranges of cells for calculations with the following
operators.
Reference Operator Meaning Example
: (Colon) Range operator, which
produces one reference to all
the cells between two
references, including the two
references.
(A1:A10)
, (Comma) Union operator, which
combines multiple references
to one reference.
(A1:A10,B1:B10)

Contd…
References:
When you use a cell (or range) reference in a formula, you
can use three types of references:
Relative: The row and column references can change
when you copy the formula to another cell because the
references are actually offsets from the current row and
column. By default, Excel creates relative cell references in
formulas.
Absolute: The row and column references do not change
when you copy the formula because the reference is to an
actual cell address. An absolute reference uses two dollar
signs in its address; one for the column letter and one for
the row number (For example, $A$5).
Mixed: Both the row or column reference is relative, and
the other is absolute. Only one of the address parts is
absolute (For example, $A4 or A$4).

Four Functions
Addition:
The simplest Excel addition formula calculates the
sum of numbers and returns the result.

Contd…
Instead of using the + operator, as shown above, you
can use the Sum function in your Excel addition
formula.

Contd…
Subtraction:
The simplest Excel subtraction formula subtracts the
numbers and returns the result.

Contd…
Multiplication: The basic formula for performing
multiplication in Excel, calculates product of the numbers
and returns the result.
Instead of using the * operator, as shown above, you can use
the Product function to perform a multiplication in Excel.

Contd…
Division:
The most basic formula to divide in Excel division,
divides the number and returns the result.

Displaying Percentage
Percentages in Excel are stored as decimal values. For
example, 25% is stored as the value 0.25, 50% is stored as
the value 0.5, etc.
It is only the formatting of a cell that makes the decimal
value appear as a percentage.
Two Percentage Calculation Types
When calculating percentages in Excel, there are two types
that are typically used. These are:
Percentage as a Proportion: Example: if, out of 120
questions, you answer 90 correctly, how is this expressed
as a percentage score?

Contd…
Percentage Change: Example; if your sales figures are
$1,250 in January and $1,750 in February, what is the
percentage increase in February, compared to January?
1. How to Calculate a Percentage as a Proportion
If you want to calculate a sample of a full set, as a
percentage, this is done by dividing the sample size by
the size of the full set.
For example, if you take an exam and answer 90 out of
120 questions correctly, this can be expressed as a
percentage by simply dividing 90 by 120.

Contd…
This gives the result 0.75, or 75%
2. How to Calculate Percentage Change
If you want to calculate the percentage change between
value A and Value B, this is done using the following
formula.

Contd…
Percentage change = (b-a)/a
For example if your sales figures are $1,250 in
January and $1,750 in February, the percentage
change in February, compared to January, is given
by:

during the lifetime of the loan. For example, if a car is
financed in 5 years, this value would be (5 years * 12
months each = 60 months). When passing this
argument, you must remember to pass the right
amount.

FV (Future Value): to calculate the future value of
an investment, you can use the FV() function.
The syntax of this function is:
FV (Rate, Periods, Payment, PresentValue,
PaymentType)

Contd…
NPER (Number of Periods): To calculate the
number of periods of an investment or a loan, you can
use the NPER() function.
Its syntax is:
NPER (Rate, Payment, PresentValue,
FutureValue, PaymentType)

Contd…
PMT (Investment or Loan Payment): The PMT()
function is used to calculate the regular payment of
loan or an investment.
its syntax is:
PMT (Rate, NPeriods, PresentValue,
In the following example, a custorer is applying for a
car loan. The cost of the car will be entered in cell B3. It
will be financed at a rate entered in cell B5 for a period
set in cell B6.

Contd…
Suppose that, during the evaluation, a customer decides that
she doesn’t need a brand new car anymore. Also, she thinks
that a 5-year car loan is too long. Furthermore, she wants to
make a $4500.00 down payment to reduce the monthly
payments. On the other side of the desk, the salesperson who
wants to make a juicy commission on this loan has decided to
increase the interest rate.

 The Amount Paid as Interest During a Period:
When a customer is applying for a loan an investment
company must be very interested to know how much money it
would collect as interest. This allows the company to know
whether the loan is worth giving. Because the interest earned is
related to the interest rate, a company can play with the rate
(and also the length) of the loan to get a fair (?) amount.
- The IPMT() function is used to calculate the amount paid as
interest on a loan during a period of the lifetime of a loan or an
investment. It is important to understand what tis function
calculates. Suppose a customer is applying for a car loan and
the salesperson decide (or agrees with the customer) that the
loan will be spread over 5 years (5 years * 12 months each = 60
months). The salesperson then applies a certain interest rate.

Contd…
IPMT: The IPMT() function can help you calculate the
amount of interest that the lending institution would
earn during a certain period. In essence, you can use
it to know how much money the company would earn
in the 3rd year, or in the 4th year, or in the 1st year.
Based on this, this function has an argument called
Period, which specifies the year you want to find out
the interest earned in.
The syntax of the IPMT() function is:
IPMT (Rate, Period, Nperiods, PresentValue,

Contd…
The Amount Paid as Principal:
While the IPMT() function calculates the amount paid as
interest for a period of a loan or an investment, the
PPMT() function calculates the actual amount that
applies to the balance of the loan. This is referred to as
the principal.
Its syntax is:
PPMT (Rate, Period, Nperiods, PresentValue,

Contd…
The arguments are the same as described in the
previous sections.

Contd…
The Interest Rate:
Suppose a customer comes to a car dealer and wants to buy a
car. The salesperson would first present the available cars to
the customer so the customer can decide what car he likes.
After this process and during the evaluation, the sales person
may tell the customer that the monthly payments would be
$384.48. The customer may then say, “Wooooh, I can’t afford
that, man”. Then the salesperson would ask, “What type of
monthly payment suits you”. From now on, both would
continue the discussion. Since the salesperson still wants to
make some money but without losing the customer because of a
high monthly payment, the salesperson would need to find a
reasonable rate that can accommodate an affordable monthly
payment for the customer.

Contd…
The RATE() function is used to calculate the interest
applied on a loan or an investment.
Its syntaxis:
RATE (NPeriods, Payment, PresentValue,
FutureValue, PaymentType, Guess)

Contd…
IRR (The Internal Rate of Return): The IRR()
function is used to calculate an internal rate of return
based on a series of investments.
Its syntax is:
IRR (Values, Guess)

Contd…
The values argument is a series (also called an array or a
collection) of cash amounts that a customer has made on an
investment. For example, a customer could make monthly
deposits in a savings or credit union account.
Another customer could be running a business and receiving
different amounts of money as the business is flowing (or losing
money). The cash flows don’t have to be the same at different
intervals but they should (or must) occur at regular intervals such
as weekly (amount cut from a paycheck), bi-weekly (401k directly
cut from paycheck monthly (regular investment), or yearly
(income).
The values argument must be passed as a collection of values,
such as a range of selected cells, and not an amount. Otherwise
you would receive an error.
The Guess parameter is an estimate interest rate of return of the
investment.

Contd…
NPV Net Present Value: The NPV() function uses a
series of cash flows to calculate the present value of
an investment.
Its syntax is:
NPV (Rate, Value1, Value2, …)

Contd…
The Rate parameter is the rate of discount during one
period of the investment.
As the NPV() function doesn’t take a fixed number of
arguments, you can add a series of values as Value1,
Value2, etc. These are regularly made payments for
each period involved. Because this function uses a
series of payments, any payment made in the past
should have a positive value (because it was made
already). Any future payment should have a negative
value (because it has not been made yet).

Convert Functions
Weight Convert: Converts a number from one
measurement system to another. For example,
CONVERT can translate a table of weight in gram to a
table of weight in slug.

Contd…
Distance Convert: Converts a number from one
measurement system to another. For example,
CONVERT can translate a table of distances in inch to
a table of distances in foot.

Contd…
Time Convert: Converts a number from one
measurement system to another, For Example,
CONVERT can translate a table of time in year to a
table of time in hour.

Contd…
Temperature Convert: Converts a number from
one measurement system to another. For example,
CONVERT can translate a table of temperature in
Celsius to a table of temperature in Fahrenheit.

Array Functions (Database)
An array formula is a formula that works with an
array, or series, of data values rather than a single
data value.
