Calculating Time Value of Money
Use time-value-of-money (
TVM) functions (menu items 2 through 6) to analyze financial
instruments such as annuities, loans, mortgages, leases, and savings.
Each
TVM function takes zero to six arguments, which must be real numbers. The values that you
specify as arguments for
TVM functions are not stored to the TVM variables.
Note: To store a value to a TVM variable, use the TVM Solver or use ¿ and any TVM variable
on the
FINANCE VARS menu.
If you enter less than six arguments, the TI-84 Plus substitutes a previously stored TVM variable
value for each unspecified argument.
If you enter any arguments with a
TVM function, you must place the argument or arguments in
parentheses.
