I wrote this blog post as part of blog series on growth and marketing. See more here: Growth Map: The Missing Guide That Connects Marketing Strategy, Research, and Campaigns.

Startup founders, marketing managers, and growth hackers who are new to the growth game. Anyone who’d like to understand basic business metrics tech startups use. Here is why you might care:

  • You’d like to evaluate performance of your marketing
  • You’re raising a new round and want to be ready for the questions VCs are going to ask

So, let’s dive right in.

What We’ll Cover

Last time we focused on user growth. We looked into acquisition, retention, and virality metrics, as well as interactions among these three. Today, we’ll assess the dollar impact one user has on our business. To do it, we’ll learn to calculate and use another metric: customer lifetime value.

Summary (TL;DR)

  • Customer Lifetime Value (CLV) = dollar value a company can earn from serving one customer.
  • Retention ↑ => CLV ↑
  • Price ↑ => CLV ↑
  • Discount rate ↑ => CLV↓

What We’ll Cover

First, we’ll focus on user growth. Here we’ll look into acquisition, retention, and virality metrics, as well as interactions among these three.

Second, we’ll focus on the monetary value associated with users. Here we’ll look into customer lifetime value and customer acquisition cost.

Mental Math: Years to Double an Investment

Sharing a very simple, but handy mental math rule that was mentioned in quite a few of our MBA classes, such as Investment Styles and Strategies, Designing Financial Models that Work and others:

If you want to quickly ballpark the # of years it will approximately take for an investment to double, then just divide 72 by the annual growth rate. For example, if your investment grows 7% a year, it will take slightly more than 10 years for it to double (72/7). But if it grows 36% a year, it will only take about two years to double (72/36). 

You can read more about this “Rule of 72” on Wikipedia. Now, you now you can come across as a math genius without much effort 😉
