Custome acquistion and life time value

Customer acquisition (CAC)CAC and Life Time Value (LTV) have been key metrics over the past 20 years. It is a key element of startups that many are a little backward in understanding. Some use other words to describe it.  During the fast few years though, there has been lots written about the two most critical variables.

Twenty years ago the most important phrase was “cash is more important than your mother”. That is true for business. I have seen lots and experienced a couple where we did not focus properly on the money.

This article is taken from ForEntrepreneurs. so go to that site for more information. In summary:

In it, David Skok proposes that in addition to team, product, and market, there is actually a fourth, equally important, core element of startups, which is the need for a viable business model. Business model viability, in the majority of startups, will come down to balancing two variables:

  • Cost to Acquire Customers (CAC)
  • The ability to monetize those customers, or LTV (which stands for Lifetime Value of a Customer)

Successful web businesses have long understood these metrics as they have such an easy way to measure them. However there is a lot of value in looking at these same metrics for all other businesses.

Customer Acquistion

To compute the cost to acquire a customer, CAC, you would take your entire cost of sales and marketing over a given period, including salaries and other headcount related expenses, and divide it by the number of customers that you acquired in that period. (In pure web businesses where the headcount doesn’t need to grow as customer acquisition scales, it is also very useful to look customer acquisition costs without the headcount costs.)

Life Time Value

To compute the Lifetime Value of a Customer, LTV, you would look at the Gross Margin that you would expect to make from that customer over the lifetime of your relationship. Gross Margin should take into consideration any support, installation, and servicing costs.
