1. Problem Recognition, Definition and Evaluation
According to engineering economy book, we can become
millionaire if we start saving early. And even we are getting old is never too
late to start for saving.
In this case I want to save money by investing in
gold.
According to London fix historical gold Retrieved
from http://www.kitco.com, Gold prices increase
per year average 17.46%.
Gold investment is relatively safe and also more
liquid than other investment. If we want to compare with bank deposit which is
only return 6%/year than Gold can return almost 3x higher. But again gold
investment is for long term project.
2.
Feasible alternatives
I found three ways to invest in gold.
a.
Buying physical gold directly in
gold shop
b.
Buy gold via saving at Bank (Bank Syariah)
c.
Buy gold via Mortgage (Pegadaian)
Using engineering economy we want to analyze which
one is more profitable.
3.
The cash flow for each feasible
alternatives
Analysis using for 100 gram gold coin/bullion
a.
Buying physical gold which is cost for 100 gram at
4 December 2012 was $5,420
b.
Buy gold via Islamic Bank (Bank Syariah).
According
to Bank Account officer the term and condition for buying gold, we should pay
initial payment for 20% plus administration cost and the rest we should save by
monthly plus saving cost for 4 month.
The cash
flow can be shown at below table:
c.
Buy gold via Mortgage (Pegadaian)
The cash
Flow can be shown at below table:
4.
Selection of the acceptable criteria.
Using engineering economy we will compare the IRR and
annual effective rate from above option.
The bigger IRR than the better investment.
5.
Analysis for the alternatives
Using Ms. Excel spreadsheet we can calculate the
proposal as below table:
a. Buying
physical gold which is cost for 100 gram at 4 December 2012 was $5,420
With i = MRR
= IRR = 17.46% effective annual interest.
b. Buy
gold via Islamic Bank (Bank Syariah).
c.
Buy gold via Mortgage (Pegadaian)
6.
Select the preferred alternative
Based from above calculation IRR for direct buying is
the bigger.
So if we have liquid money it is better to buying
directly in gold shop, but if you do not have it, you can buy at Bank Syariah
which is better than Pegadaian.
7.
Performance Monitoring & Post
Evaluation of Result
Performance and the quality of these calculations could
be monitor by checking gold price movement by monthly or yearly.

Another very innovative and imaginative way to apply Engineering Economy to solve a real life problem. I loved the case study....
ReplyDeleteIf you are interested in this topic (and who isn't!!??) why not compare investing a fixed sum in gold, property, or the stock market. Run a pure financial comparison then run a risk factored comparison. Use historical data as the basis for comparing all three options.
Keep up the good work!!
