To get the dialog box, click on fx, then Financial, then FV, then OK.
Inputs:
PV
=
1000
I/YR
=
10%
N
=
5
Formula:
FV = PV(1+I)^N =
$1,610.51
Wizard (FV):
$1,610.51
Experiment by changing the input values to see how quickly the output values change.

a.
Find the FV of $1,000 invested to earn 10% annually 5 years from now.
Answer this question by using
a
math formula and also by using the
Excel
function wizard.
Note:
When you use the wizard and fill in the menu items, the result is the formula you see on the formula line if
you click on cell E12.
Put the pointer on E12 and then click the function wizard (fx) to see the completed menu.
Also, it is generally easiest to fill in the wizard menus by clicking on one of the menu slots to activate the cursor
and then clicking on the cell where the item is given.
Then, hit the tab key to move down to the next menu slot
to continue filling out the dialog box.
b.
Now create a table that shows the FV at 0%, 5%, and 20% for 0, 1, 2, 3, 4, and 5 years.
Then create a
graph with years on the horizontal axis and FV on the vertical axis to display your results.
Begin by typing in the row and column labels as shown below. We could fill in the table by inserting formulas in
all the cells, but a better way is to use an Excel data table as described in 07model.
We used the data table
procedure.
Note that the Row Input Cell is D9 and the Column Input Cell is D10, and we set Cell B32 equal to
Cell E11.
Then, we selected (highlighted) the range B32:E38, then clicked Data, Table, and filled in the menu
items to complete the table.
To create the graph, first select the range C33:E38.
Then click the chart wizard.
Then follow the menu. It is easy
to make a chart, but a lot of detailed steps are involved to format it so that it's "pretty."
Pretty charts are
generally not necessary to get the picture, though. Note that as the last item in the chart menu you are asked if
you want to put the chart on the worksheet or on a separate tab.
This is a matter of taste.
We put the chart below
on the spreadsheet so we could see how changes in the data lead to changes in the graph.
