Customer
Equity Calculations
Calculating
Acquisition Equity
A
simple example will illustrate the calculation of Acquisition
Equity. Firm A's sales department began the process by obtaining
data from its sales tracking system about prospects targeted in
1995. Interactions with these prospects occurred over a one-year
period, after which the firm no longer considered them
prospects.
 |
Step
1:
|
Determine
the number of prospects contacted over a fixed time
period from a cohort that is no longer likely to
purchase for the first time. In this example, there
were 10,000 prospects over a one-year period.
 |
| |
Step
2: |
Measure
the marketing and servicing costs associated with
contacting and selling to the prospects. The firm
determined that the sales organization made 20,000 sales
calls over the "life" of the prospects, at an
average cost of $50.00 per sales call. Additionally,
direct-mail materials cost $0.50 per prospect.
Incremental administrative expenses associated with
prospects were $200,000. The total cost of contacting
prospects thus came to $1,205,000 (1,205,000 = 20,000*50
+ 10,000*50 + 200,000).
 |
| |
Step
3: |
Determine
the number of prospects who became customers. Of the
10,000 prospects, 1,000 became customers. This equates
to an acquisition response rate of .1, or 10 percent
(10,000/1,000 = 0.1).

|
| |
Step
4: |
Compute
the sales revenue and gross margin for the new
customers' first set of purchases. On average a
customer purchases $1,750 per period at a gross margin
of 35 percent, yielding a net profit of $612.50 per
initial purchase per customer. Multiplied by 1,000
customers, this comes to a total net profit of $612,500
on first purchases.
 |
| |
Step
5: |
Compute
the acquisition equity of the entire pool of customers. The
profit was $612,500 (Step 4) and the acquisition costs
(Step 2) were $1,205,000. The acquisition equity equals
$612,500 - $1,205,000 = ($592,500).
 |
| |
Step
6: |
Divide
the total acquisition equity by the number of customers
to determine the acquisition equity per customer.
The net loss was ($592,500) for 1,000 customers,
which comes to a net loss of $592.50 per customer
acquired. |
You
can see from these steps that it can be difficult to obtain the
data needed for these computations. In the above example, Firm A
had to track the number of calls and the marketing activity
associated with prospects, and it had to cull the subset of new
customer sales from all customer sales data. Many firms do not
have the discipline or foresight to collect these data, but the
most effective customer equity management firms do collect them.
