**Instructions: Use the accompanying Excel spreadsheet to calculate the costs and profit margins of the three different office visits using i) the RCC method and ii) TDABC (Time-Driven Activity-Based Costing) method. Report the costs and profits in a small table. What explains the difference in costs and profits using the two methods.

**Here is the excel sheet! Below the excel are the instructions and formula on how to complete the calculations

**Here are the formulas for both the RCC method and ii) TDABC (Time-Driven Activity-Based Costing) method. Use these formulas to answer above

1. RCC method

The Ratio-of-Cost-to-Charges Method calculates cost from the equation below:

Actual Charge x RCC Ratio = RCC Cost

The margin is then calculated using the following:

Average Reimbursement -RCC Cost = RCC Margin

The results of these calculations are summarized below for each procedure.

Medical Diagnosis Cost per patient visit	Actual Charge	RCC Ratio	RCC Cost	Average reimbursement	RCC Margin
						Plagiocephaly	$ 350	60%	$ 210	224.00	$ 14.00
Neoplasm skin excision	$ 350	60%	$ 210	224.00	$ 14.00
Craniosynostosis	$ 350	60%	$ 210	224.00	$ 14.00

2. TDABC method

Time-Driven Activity-Based Costing calculates costs based on the amount of time is spent by each person involved in a procedure. First, a capacity cost rate is determined by dividing the total annual cost of a person by the number of available minutes annually.

Capacity per cost rate ($ minute)	Surgeon	ASR	RN	CA
	$ 6.00	$ 1.00	$ 1.50	$ 0.80

Next, the number of minutes spent on each diagnosis is multiplied by the determined rates to produce the following charges:

Medical Diagnosis Cost per patient visit	Personnel Charges				TDABC Cost
	Surgeon	ASR	RN	CA
Plagiocephaly	$ 108.00	$ 8.00	$ 34.50	$ 4.00	$ 154.50
Neoplasm skin excision	$ 132.00	$ 55.50	$ 30.00	$ 4.00	$ 221.50
Craniosynostosis	$ 240.00	$ 10.50	$ 34.50	$ 8.00	$ 293.00

The margin is calculated by subtracting the TDABC amount from the reimbursement amount.

Medical Diagnosis Cost per patient visit	Actual Charge	Average reimbursement	TDABC Method
			TDABC Cost	TDABC Margin
					Plagiocephaly	$ 350	224.00	$ 154.50	$ 69.50
Neoplasm skin excision	$ 350	224.00	$ 221.50	$ 2.50
Craniosynostosis	$ 350	224.00	$ 293.00	$ (69.00)
