HP 12C programming Message #1 Posted by Adele Berger on 27 Sept 2006, 3:13 p.m. Do you happen to have a copy of the many steps it takes to program an HP 12C so that I can figure out a rate factor, using a discount rate, term, points, advances, etc? i.e., 36 (term in months)store 0, 2 (advance payments) store 1, 1.04 (4 points gross profit)store 2, 0 (end of lease residual)store 3, 10% (our cost of funds/yield)store 4, hit the R/S button, it calculates and I get a rate factor? I must have misplaced my instructions when I moved my office down the hall. Help!

If that is the answer you want then the above prog does the job. Cheers, Tony I found it on my palmtop - ignore the comments. Hope this works. PMT for lease with residual 48 STO 0 15 ENTER 12 / STO 1 1.25 22000 STO 2 30 % STO 3 6600 (SHOULD be shown in example) 4 STO 4 R/S 487.29 Keystrokes |Display | Comments [f][P/R] | | [f]CLEAR[PRGM] |00- | [g][END] |01- 43 8 | [f]CLEAR[FIN] |02- 42 34 | [RCL]0 |03- 45 0 | [n] |04- 11 | full term [RCL]1 |05- 45 1 | [i] |06- 12 | [RCL]3 |07- 45 3 | residual [FV] |08- 15 | [PV] |09- 13 | - pv of residual [RCL]2 |10- 45 2 | [+] |11- 40 | [STO]5 |12- 44 5 | Loan-pv resid 0 |13- 0 | [FV] |14- 15 | [RCL][n] |15- 45 11 | [RCL]4 |16- 45 4 | [-] |17- 30 | [n] |18- 11 | 1 |19- 1 | [CHS] |20- 16 | [PMT] |21- 14 | [PV] |22- 13 | pv for pmt of 1 [RCL]4 |23- 45 4 | #pmt in adv [+] |24- 40 | [RCL]5 |25- 45 5 | could just be / [x<>y] |26- 34 | r5 not needed really [/] |27- 10 | [f][P/R] | | Edited: 27 Sept 2006, 5:00 p.m.
