(11C) TVM for HP11C
TVM program that work just like HP12C.
Program credit to Gene Wright's website https://www.rskey.org/gene/hpgene/tvm19c.htm As mentioned in Gene Wright page this program originally appeared in the May 1980 PPC Journal written by Robert Meyer. The program will run as written on an HP19C/29C Since 19C doesn't have specific Labels. I modify this program so that Labels A to E located at the same position as on HP12C With addedon Labels and use many Store Registers this took me awhile to make this program work since 11C got limited program space when use a lot of store memory registers. Finally I have successfully fit this program to work on 11C at which it use 111 program lines at its maximum limit. Lastly this might be an excellent TVM program for 11C compare to that of the more sophisticated TVM program available in the 15c advanced functions handbook that use SOLVE function to solve for unknown interest.

RE: (11C) TVM for HP11C
Last post I didn’t give an example on how to use this TVM program.
These two example are from the HP12C User’s Handbook. ————————————————————————————— USER mode with FIX 2 What annual interest rate must be obtained to accumulate $10,000 in 8 years on an investment of $6,000 with quarterly compounding? 8 [ENTER] 4 [x] [A] display 32.00. // Calculates and stores n. 6000 [CHS] [C] display –6,000.00 // Stores PV (with minus sign for cash paid out). 10000 [E] display 10,000.00 // Stores FV. [B] [R/S] display 1.61 // Periodic (quarterly) interest rate. 4 [x] display 6.44 Annual interest rate. Remark: This problem is in END mode the default setting with 0 on Register .0 —————————————————————————————— If you deposit $50 a month (at the beginning of each month) into a new account that pays 6 1/4% annual interest compounded monthly, how much will you have in the account after 2 years? Beginning Mode set 1 on Register .0 // ( 1 [STO] .0 ) 2 [ENTER] 12 [x] [A] display 24.00 // Calculates and stores n. 6.25 [ENTER] 12 [÷] display 0.52 // Calculates and stores i. 50 [CHS] [D] display –50.00 // Stores PMT (with minus sign for cash paid out). [E] [R/S] display 1,281.34 // Balance after 2 years. ————————————————————————————— Gamo

Interest Rate Solver Solutions for
1. Direct Reduction Loan Interest Rate with known [n, PV and PMT] 2. Sinking Fund Interest Rate with known [n, FV and PMT] This program is adapted form the HP55 Mathematic Programs  Procedure: [USER] mode [FIX] 2 Input n [A] PV or FV [ENTER] PMT [R/S] Your Guess [R/S] For Suggested Guess Problem with PV use [B] Problem with FV use [D] [C] Solve for Direct Reduction (Problem involve PV and PMT) [E] Solve for Sinking Fund (Problem involve FV and PMT)  Example: 1. Problem involve: n, PV and PMT n=12 PV=5,000 PMT=500 12 [A] 5000 [ENTER] 179.86 [R/S] display 27.80 Use Suggested Guess: [B] display 3.06% [C] display answer: 2.92%  2. Problem involve: n, FV and PMT n=12 FV=5,000 PMT=400 12 [A] 5000 [ENTER] 400 [R/S] display 8.33 Use Suggested Guess [D] display 0.75% [E] display answer: 0.74%  Program: Code:
