functions Define the amortization table Use functions in amortization tables

Separate and Combine Text
Convert text to columns Use the Text to Columns command to split the contents in
one column into separate columns Allow enough columns to the right of the column to be split
so data is not overwritten Use the CONCATENATE function to combine text
entries Join two or more text strings into one text string Permits you to include the comma or space separators in
the text string Remove duplicate rows of data

Manipulate Text with Functions
The PROPER function capitalizes the first letter in a text string and any other letters in text that follow any character other than a letter
The UPPER function converts text strings to uppercase letters
The LOWER function converts all uppercase letters in a text string to lowercase
The SUBSTITUTE function substitutes new text for old text in a text string You use the SUBSTITUTE function when you want to
replace specific text in a text string

Manipulate Text with Functions
Text functions often used in combination or as Nested functions
Nested functions are functions within another function

Identify and Remove Duplicate Rows
If the table is large, it may be more difficult to identify duplicates
Use conditional formatting techniques to identify duplicates This creates a dynamic option and continues to
work even as records with duplicated values are added

Group and Subtotal Data
Grouping enables you to consolidate related rows or columns into single units You can then collapse the group to make it easier
to view only what you want to see Excel will not create an outline or group data
if no formulas exist in the worksheet

Group and Subtotal Data
Copyright © 2008 Pearson Prentice Hall. All rights reserved. 10
Group and Subtotal Data
Use the Subtotal command to insert a subtotal row where the value of the designated field changes The Subtotal command uses a summary function
to compute subtotals within a sorted data table The records are grouped according to the value
of a specific field A grand total is displayed after the last record

Working with Windows
You may need to have several workbooks open at one time When you want to compare data from one workbook to
another, or When you want to combine data from several individual
workbooks in to one comprehensive workbook The arrangement of windows can be changed as
often as necessary to view the data you must work with

Working with Windows
Splitting a window is the process of dividing a worksheet window into two or four resizable panes
A splitter control is the two-headed arrow in the scroll bar used to divide a window into panes Drag the horizontal splitter bar to divide the window pane
into upper and lower (horizontal) panes Drag the vertical splitter bar to split the window pane into
left and right (vertical) window panes This option will turn on synchronized scrolling which causes
cells in all panes to scroll at the same time

Working with Windows
Horizontal splitter bar
Vertical splitter bar

Using Conditional Functions
Use SUMIF, COUNTIF, and AVERAGEIF to return the total, count, or average for one criterion
Use SUMIFS, COUNTIFS, and AVERAGEIFS to return a total, count, or average based on two criteria
Copyright © 2008 Pearson Prentice Hall. All rights reserved. 16
Using Conditional Functions
The SUMIF function adds the cells specified by a given criteria
The COUNTIF function counts the number of cells within a range that meets the given criterion
The AVERAGEIF function returns the average of all the cells in a range that meets a given criterion

Using Conditional Functions
The SUMIFS function adds the cells in a range that meet multiple criteria
The COUNTIFS function counts the number of cells within a range that meet multiple criteria
The AVERAGEIFS function returns the average of all the cells that meet multiple criteria

Creating Nested IF Functions
The IF function enables two possible formulas: when the logical text is true, the first formula is
used when the logical test is false the second formula is
used By nesting multiple IF statements in one
formula, you can have more than two options

Using AND, OR, NOT, and IFERROR Functions
Use the AND function to test when more than one condition is met
Use the OR function to test whether any of the arguments are true
NOT functions reverse the logic, true becomes false and false becomes true It is not recommended that you use the NOT function
The IFERROR function returns a value you specify if a formula evaluates to an error

Define the Amortization Table
An amortization schedule shows the date of each loan payment, the amount of each payment that goes to principal and interest, and the remaining balance
Allows you to see how payments on a loan are distributed, eventually leading to a zero balance
Change any one parameter and all values recalculate automatically
Useful for purchases such as car loans and home mortgages

Use Functions in Amortization Tables
Use date functions DAY, MONTH, and YEAR for calculating payment dates, the actual number of payments, and the actual payoff date of a loan
Use the MATCH function to return the relative position of an item in an array that matches a specified value in a specified order

Use Functions in Amortization Tables
Use the INDEX function to return a value or the reference to a value within a table or range
Use the ROUND function to round a value to a specified number of digits
The PMT (payment) function is used to return a payment amount based on three required arguments; the interest rate per period, the number of periods, and the principal
