The Ultimate Wealth Metric

The single most dangerous error small business owners make is viewing transactions in a vacuum. A $100 service call isn’t worth $100. It is an audition to become their trusted advisor for the next decade.

How to use this calculator

  1. Select your standard Initial Job Ticket. (e.g., $150 tune up).
  2. Enter the value of a yearly maintenance contract (PMA). Do you charge $250 a year for spring/fall cleanings?
  3. Calculate Years Retained (If you provide good service, 7 to 10 years is very common).
  4. Evaluate Referral Spread. Does an average good client recommend you to their neighbors? What is the value of those massive neighbor-jobs?

When you input these basic numbers, the underlying algorithm will show you the True Financial Value of picking up the phone when a lead calls.

Frequently Asked Questions

CLV is the total gross revenue a business can reasonably expect from a single customer account throughout their relationship with the company. It factors in baseline transactions, recurring cross-sells, and organic referrals.
If you know a single customer will ultimately spend $8,500 with you over 10 years, you suddenly realize you can afford to spend $800 on Google Ads just to acquire them. Your competitors, who only look at the $200 initial margin, will stop spending on ads. You will acquire all the market share.
