OpenOffice calc online tutorial
Example spreadsheet,
savetoretire.ods.
Naming a cell or range of cells:
select cell(s), click Name box, type name, hit Enter key.
Using a name:
in a cell, type = followed by a name
(instead of a number, formula, string, etc.).
Deleting a name:
Insert > Name > Define, select name, click Delete button.
To format a cell or cell range for currency, percentage, etc.:
select cell or cell range, right-click and select Format Cells,
click Number tab if necessary.
Relative cell address (no leading dollar signs $ on row or column)
changes (adjusts) when copied.
An absolute cell address (leading $ on row and/or column)
does not change when copied.
Using functions:
Insert > Function
Functions: FV, PV, PMT
Using the following symbols
- y for number of years,
- i for annual interest rate or investment return,
- a for amount (dollars) per year,
and
- t for total dollars,
we use the functions FV, PV, and PMT to answer the following questions.
- Given specific values of i, y, and t,
PMT(i, y, 0, t, 1)
calculates how many dollars a we need to save
per year (at the beginning of each year)
for y years to accumulate t total dollars.
- Given specific values of i, y, and t,
PMT(i, y, t, 0, 1)
calculates how many dollars a we can pay ourselves
in retirement per year (at the beginning of each year)
for y years if we have saved t total dollars.
- Given specific values of i, y, and a,
FV(i, y, a, 0, 1)
calculates how many total dollars t we accumulate
in a savings account after saving a dollars per year
(at the beginning of each year) for y years.
- Given specific values of i, y, and a,
PV(i, y, a, 0, 1)
calculates the one-time lump-sum savings to put in a savings
account at year one so that at the end of y years,
the savings account has in it the same amount as if we had
invested a dollars per year
(at the beginning of each year) for y years.
(The previous bullet tells us how to calculate what that
total t actually is:
FV(i, y, a, 0, 1).)
- Given specific values of i, y, and a,
PV(i, y, a, 0, 1)
also calculates the total dollars t needed to pay out
a dollars per year
(at the beginning of each year) for y years.
