Shore - 03-16-2014 11:26 PM Input - Store before running: R0 = months to retirement R1 = months of retirement (annuity) PMT = monthly annuity payment i = discount rate Output: 1. Press R/S to get the value of all annuity 2. Press R/S to get the present value of the deferred annuity Program: Key : Step - Key Code 0 : 01- 0 FV : 02 - 15 RCL 1 : 03 - 45, 1 n : 04 - 11 PV : 05 - 13 R/S : 06 - 31 CHS : 07 - 16 FV : 08 - 15 0 : 09 - 0 PMT : 10 - 14 RCL 0 : 11 - 45, 0 n : 12 - 11 PV : 13 - 13 GTO 00 : 14 - 43, 33, 00 Note: This is done on a "classic" HP 12C. With a HP 12C Platinum, use RPN mode and replace GTO 00 with GTO 000. Example: An annuity that will pay \$2,000 a month for 324 months (27 years) will be paid 312 months (26 years) from now. Assume an annual discount rate of 5.5% (periodic rate of about 0.4583%). Steps: 324 STO 0 312 STO 1 5.5 g 12รท 3000 PMT R/S: Result: -505,785.53 R/S: Result: -121,435.08 The annuity needs to be funded with \$121,435.08 in order to meet the required payment structures 26 years from now. RE: Deferred Monthly Annuity for the HP 12C - bshoring - 06-26-2016 09:33 PM Hi Eddie, Thanks for posting this useful program. A bit late for me as I'm already retired, but I'm happy to get it and use it nonetheless. I think for the example you gave the 324 and 312 should be reversed. When I first tried it, I got different results, but when I put 312 in R0 & 324 in R1, I got the correct result, as long as the calculator is in "END" mode.
