HP-34C Owner's Handbook demonstrate the program that computes and pauses to display the future value [FV] of a compound interest saving account in increments of one year according to the formula: FV = PV(1+i)^n
Since 12C already have TVM formula build-in this make programing much shorter than the 34C version.
This program is very handy when you like to see your saving grow through the incrementing years.
How to operate: f [FIN] f [REG]
Input [i] and [PV] then [R/S] the program will continue running until you press any key to stop, or until the 12C overflows.
Remark: PV must be negative according to the Cash Flow Sign Convention
Example:
Initial interest rate 6% [i]
Initial deposit of $1000 [PV]
6 > [i]
-1000 > [PV]
[R/S]
Answer: 1st year, $1060; 2nd year, $1123.60; 3rd year $1191.02; etc.
For reference this is the program from 34C Owner's Handbook
To run:
.06 ENTER 1000 CHS f A
If add EEX 2 ÷
6 ENTER 1000 CHS f A
