In measuring the results of your advertising, marketing and sales efforts, it is not simply enough to count the number of people who respond to your offer to buy your product/service. What you really want to know is, how much is a new customer worth to you – in dollars and cents – over his/her lifetime. 

Determining the lifetime value of a customer is the first step in deciding how much you should be willing to spend to get a new customer.  Also, you should now see how it might even be profitable to lose a little on the 1^st sale to get a new customer.

This customer lifetime value calculator will help you estimate how much your average customer is worth.
