HP 15C:  Pricing Calculations (Gamo)

Introduction

The following program is a solver for cost, price, markup, and margin – developed by Gamo, which was emailed to me. The program (shown for the HP 15C).  Program listed here with permission and much thanks and gratitude to Gamo.

Registers: 

R1 = Cost
R2 = Price
R3 = Markup
R4 = Margin

Instructions:

The program primary runs on the cost-price-markup calculation, which belongs to labels A, B, and C, respectively.

Conversions between margin and markup are used between labels D and E.  Gamo recommends that you set the calculator in FIX 2 mode and press [ f ] (USER) prior to running this program.

This program is set up to be a solver similar to the HP 12C and Hewlett Packard other financial calculators. 

Examples

It is assumed that FIX 2 is set and USER mode is turned on.

Example 1: (from Gamo)

Cost = 66.46
Price = 105.00

Keystrokes:

66.46 [ A ]
105.00 [ B ]
[ C ], Markup =  57.99
[ C ] [ D ], Margin = 36.70

Example 2: 

Cost = 2500.00
Margin = 10.00

2500 [ A ]
10 [ D ]
[ E ] [ C ] [ B ],  Price = 2777.78

Example 3:

Price = 48.75
Markup = 10.00

48.75 [ B ]
10.00 [ C ]
[ A ], Cost = 44.32

Example 4:  Margin/Markup Calculation

Markup = 54.00

54.00 [ E ]
[ D ],  Margin = 35.06
