15c pricing program
A pricing program for small businesses that build custom projects.
Pricing Program:
STACK REGISTERS USED:
T=PROJECT DAYS;
Z= MATERIAL COST;
Y=ADDITIONAL LABOR;
X= % PROFITABILITY
Code:
LBL E
ROLL DOWN
+ //ADD M & L
X<>Y //EXCHANGE (M+L) WITH DAYS
605 //DAILY OVERHEAD VALUE
* //MULTIPLY DAYS WITH DAILY OVERHEAD
+ //ADD (M+L) + (605*D)
X<>Y //EXCHANGE % PROFIT WITH (M+L) + (605*D)
CHS
100
+ //SUBTRACT PROFIT FROM 100 TO FIND DIFFERENCE
.01 //CONVERT FROM % TO DECIMAL
* //CONVERT FROM % TO DECIMAL
/ //DIVIDE TO FIND SELLING PRICE
RTNExample:
A deck will take 5 days to build. Materials will cost $3500. The owner's salary is part of the overhead (hard coded into the program) but an additional carpenter will cost $1000. The desired profit margin is 15%.

Using the % function makes it a little shorter:
Code:
LBL E
ROLL DOWN
+ //ADD M & L
X<>Y //EXCHANGE (M+L) WITH DAYS
605 //DAILY OVERHEAD VALUE
* //MULTIPLY DAYS WITH DAILY OVERHEAD
+ //ADD (M+L) + (605*D)

ROLL UP
% //CONVERT FROM % TO DECIMAL
- //SUBTRACT PROFIT FROM 1 TO FIND DIFFERENCE
/ //DIVIDE TO FIND SELLING PRICE
