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 (page 14.14).
Note: To store a value to a TVM variable, use the TVM Solver (page
14.4) or use ¿ and any TVM variable on the FINANCE VARS
menu (page 14.14).
If you enter less than six arguments, the TI-82 STATS
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.
tvm_Pmt computes the amount of each payment.
tvm_Pmt[(

Note: In the example above, the values are stored to the TVM
variables in the TVM Solver. Then the payment (tvm_Pmt) is
computed on the home screen using the values in the TVM Solver.
Next, the interest rate is changed to 9.5 to illustrate the effect on the
payment amount.
