TVM variables N I PV PMT FV PpY CpY END BEGIN Default 0 0 0 0 0 1 1 END Definition Value Type Number of payment periods Annual interest rate (converted to a per-period rate based on the values of PpY and CpY) Present value Payment amount Future value Payments per year Compounding periods per year real number real number real number real number real number integer > 0 integer > 0 Set annuity due (i. e. specify whether payment is N/A at the end or beginning of each period) When you store a value to PpY in the TVM Solver only, the value for CpY automatically changes to the same value. To store a unique value to CpY, you must store the value to CpY after you have stored a value to PpY. If you store a value to PpY outside the TVM Solver, the value for CpY does not change. [. . . ] 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. Finance Application for the STEAM COOKER à TI-92 Plus 6 tvm_PV The tvm_PV function calculates the present value. tvm_PV(N, I, PMT, FV, PPY, CPY) tvm_Pmt The tvm_Pmt function calculates the amount of each payment. tvm_Pmt(N, I, PV, FV, PPY, CPY) tvm_FV The tvm_FV function calculates the future value of money. tvm_FV(N, I, PV, PMT, PPY, CPY) Finance Functions Catalog This application adds all Finance functions to the catalog for use in calculations outside of the TVM Solver. To access them, press ½, press … (Flash Apps), and press C and D to scroll the list of Finance functions. Pressing ¸ while the indicator points to the name pastes it to the previous screen in the form of TIFinance. name. To solve for a Finance function, include the appropriate arguments (See Argument Definition Table) separated by b and ending with d. Finance Application for the STEAM COOKER / TI-92 Plus 7 Sending the Application to Another Calculator with Var-Link If you send the Finance application to another calculator, the other calculator receives the application, including all finance functions as well as the TVM variables defined to their default values (not as they might be currently defined). If you want to send stored variable values, first send the application, then send the variables using 2 °. Note: After pressing 2 °, the finance variables are listed in the Finance folder. To access the function names, press ‰ on the TI-92 Plus or 2 ‰ on the STEAM COOKER. Calculating Cash Flows Use the cash flow functions, npv and irr, to analyze the value of money over equal time periods. You can enter unequal cash flows, which can be cash inflows or outflows. The syntax descriptions for npv( and irr( use these arguments. Catalog Variables/ Arguments npv(InterestRate, CFO, CFList[CFFreq]) Definition net present value; the sum of the present values for the cash inflows and outflows. Pmt_End is the default. On the TVM Solver’s PMT:END BEGIN line, select END to set PMT to ordinary annuity. Pmt_Bgn ( ) Pmt_Bgn (payment beginning) specifies an annuity due, where payments occur at the beginning of each payment period. Most leases are in this category. On the TVM Solver’s PMT:END BEGIN line, select BEGIN to set PMT to annuity due. pmt_at pmt_at is a variable which specifies annuity due depending on what value has been stored to it. This is located in the 2 ° Finance folder. Finance Application for the STEAM COOKER à TI-92 Plus 10 Finance Examples Example 1 — Financing a Car You have found a car you would like to buy. You can afford payments of $250 per month for four years. What annual percentage rate (APR) will make it possible for you to afford the car?Press ¸ ¸ to return to previous screen. 2. Highlight Finance with the cursor and press ¸ to open the application. Enter known values: N=48; PV=9000; PMT=M250 (Negation indicates cash outflow. ); FV=0; PpY=12 (computes an annual percentage rate); CpY=12; PMT=END. Press „ Compute to solve for I%. Finance Application for the STEAM COOKER / TI-92 Plus 11 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. 1. Press ¸ ¸ to return to previous screen. 2.
