Calculating TVM Outside of the TVM Solver
All TVM and finance functions are listed in the ½ for use outside of the TVM Solver. Function calculations outside the TVM Solver do NOT save the results in memory. To save a value to a TVM variable use the following syntax: value § TVM_variable ¸ Access a TVM_variable from the VAR-LINK menu, Finance folder. TIFnance precedes a function name and finance\ precedes a variable name when pasted outside the TVM Solver. Note: The VAR-LINK Finance folder (where TVM variables are stored) is used by this application and previously-stored data can be overwritten without notification. If you enter less than six arguments, the calculator substitutes the currently 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, separated by commas (b).
tvm_N
The tvm_N function calculates the number of payment periods.
tvm_N(I, PV, PMT, FV, PPY, CPY)
tvm_I
The tvm_I function calculates the interest rate per year.
tvm_I(N, PV, PMT, FV, PPY, CPY)
Function calculations do not save results in memory.
I% is now the new rate. Use § to save the new result for i in memory.

Example 2 — Calculating Interest on a Fixed Payment
At what annual interest rate, compounded monthly, will $1, 250 accumulate to $2, 000 in 7 years?
Note: Because there are no payments when you solve compound interest problems, PMT must be set to 0 and PpY must be set to 1.
