Calculating Time Value of Money (TVM)
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 these 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-83 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.
