CBA Lab Exercise

CBA Laboratory Exercise
The new proposed automated cashiering and inventory system of G-Mall requires php 500,000 development cost. The determined economic life of the new system will be 5 years. Once the development is finished, the company will need to spend php 100, 000 for the employees training. The personnel salaries are estimated to php 500,000 per annum. The software lease (including license fee) will cost php100, 000 per year. In-house maintenance during operation will incur php 50,000.

G-mall still has old unused PC’s that can be used instead of buying brand new that will save them php 60, 000. It is expected that employees will be reduced by 50% thus saving php 500, 000 from personnel salaries and fringe benefits. Supplies and utilities will decrease saving php 36, 000.

All estimates of costs and benefits are increasing at a rate of 5% per year for both the current and new systems. The required rate of return for the company is 10%.
