Decoding Business Health with Unit Economics

June 20, 2023

Hello everyone,

Today, I want to shed light on a crucial concept in investing and finance - the unit economy of a business. Unit economics are the direct revenues and costs of a business, measured on a per-unit basis. This could be any quantifiable item that brings value to the business. Understanding unit economics makes it easier to forecast things such as break-even points and gross margins​​.

Now, you might wonder, why is this so essential? The answer lies in the way we evaluate businesses. Often, annual and quarterly reports don't tell the whole story. As renowned investors Warren Buffett and Charlie Munger have noted, "creative accounting" can sometimes make the numbers appear more attractive to investors, but this doesn't necessarily reflect the true picture. That's where understanding unit economics comes in.

A few key metrics can help us unravel the unit economy of a business. Firstly, the Lifetime Value (LTV) per customer, which compares the value of a customer over their lifetime to the cost of acquiring them. For instance, if your business' LTV is $1200 and your Customer Acquisition Cost (CAC) is $500, for every $1 spent on acquisition, you get $2 back​​.

Other vital metrics include the Churn Rate, which is the percentage of your customers that cancel their subscription during a given period, and the Retention Rate, which is the percentage of customers that remain subscribed during the same period​1​. The Average Customer Lifetime (ACL) - the average time a customer stays subscribed before they churn - is a key component in calculating their LTV​​. Gross profit (GP), calculated as your total revenue minus the cost of sales, is another key metric to consider​.

If you're planning to start your own business, understanding these metrics is even more crucial. Unit economics are the foundation that sustains your business as it scales. They can guide your attention towards the necessary aspects of your business to hit your goals. For instance, a startup company with an average customer lifetime of 22 months, and a monthly payment of $100, would have an LTV of $2,200​5​. If the CAC is $500 and the average customer pays $100 per month, the payback period would be 5 months​5​. Understanding these figures helps you predict your business's ability to turn a profit and grow efficiently​​.

In conclusion, understanding unit economics is not just beneficial but essential, whether you're an investor trying to evaluate a business or an entrepreneur planning to start your own venture. It provides a more detailed and accurate picture of a business's health and potential than traditional financial reports. So, let's dive deeper into the world of unit economics and unlock the true value of businesses!
