What was the return on marketing expenditures (gross profit as a function of marketing costs)? c. d. What was the breakeven for this campaign? The marketer now engages in RFM analysis. They identify that RFM cell 452 had a response rate of 3.10%. e. What is the breakeven index for that group?

Explanation / Answer

a.

Marketing cost = 0.55*30,000 = $16,500

Revenue = 75*970 = $72,750

Margin = 40% of revenue = 0.4*$72,750 = $29,100

Profit = Margin - Cost = 29,100 - 16500 = $12,600

so gross profit is 12,600

b.

Gross profit as % of gross sales = 12600/72,750 = 17.3%

c.

Gross profit as % of marketing cost = 12600/16500 = 76.36%

d.

Breakeven is gross profit = 0

(x is number of customers purchasing)

margin = 0.4*75*x = 30000*0.55

x = 550

so 550 customer was breakeven
