Find out what unit economics are, how to calculate them and how they can help you take your business to the next level!<\/p>\n\n\n\n\n\n\n\n\n

How do you measure the wellbeing of your business? I bet that in most cases you\u2019re looking at and analyzing your company\u2019s financial statements – P&L<\/a>, cash flow statement and balance sheet<\/a>. And you\u2019re right to do so, as P&L shows your company’s growth and profitability over time, the cash flow statement demonstrates liquidity, and the balance sheet gives you a snapshot of assets. You can understand if you\u2019re succeeding or failing overall, but these broad statements don’t give you any details. What are your most profitable products? What are your largest costs? How do these scale as your company grows? How much are you actually spending to acquire customers? How much are you taking home in profits each time an item is purchased? Lots of business owners struggle to make sense of all those important details that make a huge difference.<\/p>\n\n\n\n

This is what understanding unit economics<\/a> can help you with! Today, with the help of our experts, we\u2019re going to shed light on what unit economics are, how to track them, and how a better understanding of unit economics can help you take your business to the next level.<\/p>\n\n\n\n

For simplicity’s sake, we\u2019ll consider a retail business as an example and illustrate the intricacies of calculating the unit economics for a t-shirt at Alex\u2019s T-Shirt Store. Ready? Let\u2019s get started!<\/p>\n\n\n\n

What the heck is unit economics and why do you need to bother?<\/strong><\/span><\/h2>\n\n\n\n

Unit economics are a method or model of running a business, when you\u2019re analyzing your company\u2019s revenues and costs in relation to one unit.<\/p>\n\n\n\n

A unit here can refer to any quantifiable item that brings value to a business – an item, an order, a customer. A unit is analyzed in order to understand profit\/loss on a smaller, more digestible scale.<\/p>\n\n\n\n

Experts say<\/strong>:<\/strong><\/p>\n\n\n\n

\n

There\u2019s no right answer when it comes to defining unit economics. The way I usually describe it – a breakdown of your company\u2019s profitability through the lens of a smaller unit. And a unit here is a specific item, customer, supplier, etc. You need to track unit economics so you understand exactly how the revenue you collect for each item you sell turns into profit.<\/p>\n<\/blockquote>\n\n\n\n

The insights you get with the help of unit economics analysis are vital to your company\u2019s long- and short-term planning as they allow you to calculate break-even points, predict profitability, measure efficiency, optimize the items you deliver to your customers and much more. <\/p>\n\n\n\n

In order to calculate unit economics, you have to have a thorough understanding of what unit economics metrics you need to track. But there are some questions that need to be answered before you can do this.<\/p>\n\n\n\n

How to calculate unit economics: Asking the right questions to understand the flow<\/strong><\/span><\/h2>\n\n\n\n

There are two interrelated questions you should ask about your business: 1) Are you getting a good return on the customers you acquire?<\/em> and 2) How profitable are each of your sales?<\/em> Let\u2019s walk through these questions.<\/p>\n\n\n\n

1. Are you getting a good return on the customers you acquire?<\/h3>\n\n\n\n

Answering this question requires you to look at your customers – on average – and understand how much you\u2019re paying to acquire them and how much profit they\u2019re generating. <\/strong> This approach focuses on customer lifetime value (CLV) and customer acquisition cost (CAC).: <\/p>\n\n\n\n

Important Ratio = CLV \/ CAC<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

CLV (or LTV) represents the average profit that a business generates throughout the entire relationship with a customer. Because CLV measures the lifetime profit of a customer, this metric is dependent not only on all the typical customer-focused metrics (retention, basket size, order frequency etc), but also on the profitability of each order.<\/p>\n\n\n\n

Knowing how dependent ROI is on CLV, you try to dig deeper into the concept. To calculate CLV, you need the following formula:<\/p>\n\n\n\n

CLV = <\/strong>Revenue per Unit x<\/strong> Units per Customer x Customer Retention<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

You acquire a customer and you want your CLV to be high so that your ROI can be better. <\/p>\n\n\n\n

CAC is defined as the total investment required to acquire one customer, typically through sales and marketing. <\/p>\n\n\n\n

In essence, you can think of a customer like a savings bond. Like a bond, every customer you acquire represents future cash payments in the form of purchasing goods from your store. You want to make sure these payments are worth it for the upfront amount you need to pay for the \u201cbond\u201d, which in this case is a customer. <\/p>\n\n\n\n

Let\u2019s look at Alex\u2019s t-shirt store example, Alex paid $10 to put a flier advertising his shop under your door so that you could see it and decide to check it out. It worked! You buy one of his T-shirts. His acquisition cost to acquire you as a customer is $10. Ideally, you like it and become a returning customer. You just love his stuff! The more money you spend with Alex\u2019s business, the higher your CLV.<\/p>\n\n\n\n

It\u2019s generally considered that a good ROI on a customer is 3x: that is, the average CLV should be 3x higher than the average CAC<\/strong>. So, if Alex paid $10 to acquire you, he\u2019d want you to generate $30 in profits in return (notice this is profits not revenue – you may have spent $100 at Alex\u2019s store, but the actual money he takes home is $30 – more on that later!).<\/p>\n\n\n\n

At the same time, it might be useful to calculate the customer payback period (also known as \u2018TROI\u2019 – time to return the investment) – the time it takes to earn back the CAC. If Alex makes on average $2 for every order, and he spent $10 to acquire you, you need to order 5x for him to make up the CAC. On average it takes you 6 months to make those 5 orders, so his time to return the investment is 6 months. This simple analysis shows that in order to track unit economics, Alex first of all needs to keep tabs on such unit economics metrics as LTV and  CAC.<\/p>\n\n\n\n

Understanding the return you are getting for every dollar you spend on customer acquisition is important for any company in any industry.<\/p>\n\n\n\n

The next thing you might want to pay attention to concerns the profitability of one unit.<\/p>\n\n\n\n

2. How profitable is one unit?<\/h3>\n\n\n\n

Now you have to look at the units that you sell and take a \u2018one item sold\u2019 approach. Unit economics are determined by calculating the contribution margin, but through the lens of one unit. The margin gauges the amount of revenue from a sale minus the costs related to that sale. Basically, in order to calculate unit economics, you need to calculate everything you incur to produce, process and deliver an item to your customer and subtract it from the gross revenue. The formula looks like this:<\/p>\n\n\n\n

Contribution Margin =<\/strong> Revenue per Unit<\/strong> – Costs per Unit<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

For example, Alex\u2019s T-Shirt Store sells a specific brand of t-shirts for $100 each. If the costs to fulfill the t-shirt is $70, then the contribution margin is $30. Alex can further calculate the total contribution margin for a given period, let\u2019s say a month. If he sells 100 t-shirts in a month, then the total price of t-shirts will be $10,000 (provided that there were no special offers or discounts). The total cost in this case will be $7,000, and the total contribution margin for that month will be $3,000. <\/p>\n\n\n\n

Contribution margin represents the profitability of your business, and when you look at the contribution of one unit at a time, it can help understand the inner workings of your business.<\/p>\n\n\n\n

The \u2018one item sold\u2019 approach works best for online shops and SaaS-businesses who define units as physical goods and paid subscriptions respectively. However, some B2C platforms who define an item as one order or one delivery might also find it useful.<\/p>\n\n\n\n

While two approaches towards the way you calculate unit economics might seem contradictory and even mutually exclusive at first sight, they are in fact tied together. By improving the profitability of every order, you increase the long term value of every single one of your customers. This, in turn, improves the all important LTV\/CAC ratio. Answering two simple questions lets you understand the flow – you have to look at your business from both customer and unit perspective.<\/p>\n\n\n\n

Experts say<\/strong>:<\/strong><\/p>\n\n\n\n

\n

While each approach to calculating unit economics has its pros and cons, they\u2019re intertwined. Think of them as a kind of a lens that allows you to analyze different aspects. You\u2019d probably want to use them both for your business. However, there are types of businesses where depending on how recurring your customers are you should focus on one vs. another. 

If you\u2019re a SaaS business selling software, you represent one end of the spectrum. LTV (CLV)  and CAC are the two vital unit economics metrics you can\u2019t live without – it\u2019s all about repeat customers, retention, pricing and gross margin. Here you can focus more on customer unit economics.

But small businesses like a clothing store on the boardwalk in Disneyland are on the other end of the spectrum. Repeat customers aren’t that important – most often it\u2019s just a one-time purchase for each person. As there\u2019s no customer acquisition element, no LTV, one unit is more relevant in this case.

These are two ends of the spectrum and of course there are businesses in between. If you\u2019re loyal to Macy\u2019s, they want to make each order more profitable, but they also want to make sure that a customer keeps shopping at Macy\u2019s and they don\u2019t have to reacquire you every single time. That\u2019s why you need both.

While these two approaches to calculating unit economics are often seen as two competing mindsets, in fact, they should flow together. First, understand the ROI concept of LTV\/CAC ratio. You want to generate more money from every customer than the cost to acquire them. Then, understand that LTV = the profit of all the products purchased by a customer over their lifetime, which means not only do you need to focus on improving customer facing metrics (retention, frequency, basket size) but also improving the profitability of each item. This is the concept businesses should be tackling in a nutshell.<\/p>\n<\/blockquote>\n\n\n\n
