Problem 13-38 Target Costing in a Service Firm [LO 13-1]

[The following information applies to the questions displayed below.]

UR Safe Systems installs home security systems. Two of its systems, the ICU 100 and the ICU 900, have these characteristics:

Design Specifications	ICU 100	ICU 900	Cost Data
Video Camera	1	3	$150 each
Video monitors	1	1	$75/e
Motion detectors	5	8	$15/each
Floodlights	3	7	$8/each
Alarms	1	2	$15/each
Wiring	700ft.	1,100ft.	$0.10/ft
Installation	16hr	26 hr	$20/hr

The ICU 100 sells for $810 installed, and the ICU 900 sells for $1,520 installed.

Part 1

Required:

1. What are the current profit margin percentages on both systems?

2. UR Safes management believes that it must drop the price on the ICU 100 to $750 and on the ICU 900 to $1,390 to remain competitive in the market. Recalculate profit margin percentages for both products at these price levels and then compute the target cost needed for each product to maintain the current profit margin percentages. (For all requirements, round your percentage answers to 2 decimal places and other answers to the nearest whole dollar amount.)

	ICU 100	ICU 900
1. Current Profit Margin	10.00%	10.46
2.Profit Margin	2.80%	2.09%
Target cost	?	?

So I found for step 1:

810-729=81/810=10%

1,520-1,361=59/1,520=10.46%

Step 2:

750-729=21/750=.028=2.8%

1390-1361=29/1390=.020=2.08%

My problem is are those 4 calculations correct? And what would be the target cost?
