Unit Economics: Key Metrics for Startup Growth
By Lior Ronen | Founder, Finro Financial Consulting
Startups are like rollercoasters - thrilling, unpredictable, and full of twists and turns. And let's face it, nobody gets on a rollercoaster without knowing it's safe, right?
For startups, that safety comes from knowing your business's money matters inside out. One term you might have heard buzzing around is 'unit economics'.
Sounds fancy, doesn't it? But don't worry, it's just a smart way of asking if selling your product or service is actually making you money.
If you're a startup owner, investor, or just interested in the startup world, you'll want to get your head around unit economics.
It's a big piece of the puzzle when you're figuring out how your business is doing, and it's super important when you're planning your next moves.
In this blog post, we're going to break down unit economics and show you how it fits into your financial plan.
And the best part? We're not just going to throw boring theory at you.
We'll look at real-life stories from startups you might have heard of, like Uber, Lime, Bird, and DoorDash, to see how they've used unit economics in their business plans.
Unit economics is essential for startups, helping them understand the profitability of selling their products or services. It involves analyzing key metrics such as Customer Acquisition Cost (CAC), Customer Lifetime Value (LTV), and Gross Margin to assess financial health. By examining real-world examples from companies like Uber, Lime, Bird, and DoorDash, startups can learn how to apply these principles effectively.
Practical steps include calculating CAC and LTV, analyzing direct and indirect costs, evaluating gross margin, and continuously monitoring and adjusting strategies. Avoiding common pitfalls like ignoring indirect costs or overestimating LTV ensures accurate analysis and informed decision-making. Applying unit economics helps startups achieve sustainable, profitable growth by making strategic adjustments based on thorough financial understanding.
What is Unit Economics?
Unit economics is like taking a snapshot of your business's financial health by examining the smallest pieces, or "units," of your operations. It's about understanding if selling each unit of your product or service is profitable or not.
To do this, we focus on a few key metrics:
Customer Acquisition Cost (CAC): This is the cost of attracting a new customer. It includes all expenses related to marketing and sales, like ads, emails, events, and salaries. To find your CAC, add up these costs and divide by the number of new customers. Lower CAC means you're spending less to gain each customer.
Customer Lifetime Value (LTV): This measures the total revenue you expect from a customer during their relationship with your business. It includes all their purchases over time. For subscription services, it's about the duration of their subscription; for retail, it's about repeat purchases. Higher LTV means more revenue from each customer.
Gross Margin: This is the revenue left after subtracting the direct costs of making or delivering your product or service. It doesn’t include indirect costs like marketing or rent. A higher gross margin indicates better profitability per unit sold.
We also need to consider the costs associated with each unit:
Direct Costs: These are directly linked to producing or delivering your product or service, like materials, labor, and shipping. For example, in a ridesharing company, direct costs would include fuel, vehicle maintenance, and driver wages.
Indirect Costs: These are essential expenses not tied to a specific unit, like office rent, marketing, and administrative salaries. They generally stay the same whether you sell 100 or 1,000 units.
Some businesses may focus mainly on direct costs in their unit economics, while others might include certain indirect costs if they vary with business volume. Understanding these costs helps startups identify operational efficiencies and areas for improvement, such as optimizing processes, investing in better technology, or negotiating supplier rates.
The ultimate goal is to achieve a low CAC and high LTV, maintain a high gross margin, and keep per-unit costs manageable. This ideal scenario means you're not spending much to acquire customers, those customers are generating substantial revenue over time, and your costs per unit are sustainable.
Understanding unit economics provides a roadmap from your current financial status to where you want to be, guiding strategic decisions to drive profitability.
Next, let's explore real-world examples from companies like Uber, Lime, and Bird to see how they've applied unit economics in their business models.
Unit Economics in Practice: Case Studies
Unit economics may feel like an abstract concept until we see how it operates in real businesses. We're going to dive into the unit economics of four notable companies: Uber, Lime, Bird, and DoorDash.
Each operates in the sharing and delivery economy, a business sphere known for its tricky unit economics.
By examining these cases, we'll see how the principles of unit economics shape decision-making within these companies.
Let's dive in!
Uber
Uber, the ridesharing giant, offers a prime example of the challenges of unit economics. In its early years, Uber spent heavily on driver incentives and marketing to acquire new customers and drivers, inflating its CAC.
Additionally, their per-ride cost was relatively high due to expenses like fuel, vehicle maintenance, and driver wages. Initially, their LTV couldn't cover these costs.
As Uber grew, it managed to reduce its CAC by cutting down on driver incentives and gaining organic growth. Simultaneously, it increased its LTV by introducing higher-margin services like Uber Eats and Uber for Business.
During its Investor Day 2022, Uber highlighted cross-platform adoption as a priority, focusing on high engagement from current users and multiple product usage to increase LTV and reduce CAC.
Despite these efforts, the company still struggles with profitability, highlighting the long-term challenge of improving unit economics in a competitive market.
Lime and Bird
Lime and Bird, the electric scooter-sharing companies, face a slightly different unit economics puzzle. Their direct costs include the price of the scooters, the cost of charging and maintaining them, and relocating them to high-demand areas.
Compared to Uber, Lime and Bird have lower CAC because users typically download the app out of curiosity or seeing the scooters around town, requiring less marketing spend.
However, they face challenges with LTV. Scooters are subject to wear and tear, often needing replacement within a few months. This means they must generate enough rides (and revenue) within that period to cover the cost of the scooter and generate a profit.
Companies have tried to extend scooter lifespans and increase revenue by introducing more durable scooter models and raising prices, showing how adjustments can impact unit economics.
DoorDash
As one of the leading meal delivery services, DoorDash's unit economics center around a few key elements. Their direct costs include the cost of delivery, which involves wages for Dashers (delivery personnel) and operational costs for maintaining the app and customer service.
They also spend on marketing to acquire new customers and restaurants, forming part of their CAC.
Their LTV comes from delivery fees, commissions from restaurants, and subscription services like DashPass. Initially, DoorDash invested heavily in customer and restaurant acquisition, leading to high CAC.
The cost of delivery was also high due to competitive wages for Dashers. The company increased its LTV by adding more restaurants, including high-end ones, and introducing DashPass, a subscription service offering members free delivery for a monthly fee.
Despite these efforts, profitability in the meal delivery business remains challenging due to low margins and high competition.
DoorDash's example shows the continuous tweaking that goes into optimizing unit economics—negotiating better terms with restaurants, optimizing delivery routes to lower costs, and increasing order volume and size through promotions and partnerships.
From these examples, we see how unit economics plays out differently depending on the industry, business model, and specific circumstances of each company. Understanding and improving unit economics is key to building a sustainable business.
It's not just about rapid growth but growth that's profitable over the long term.
In the next section, we'll explore how you can apply these principles to your startup. Stick around!
Applying Unit Economics to Your Startup
We've discussed what unit economics is, the key terms and principles, and looked at real-world examples. Now, let's talk about how you can apply these principles to your own startup.
Understanding Your Costs and Revenue: Knowing where your money is coming from and where it's going is the bedrock of understanding unit economics. Here's how to get started:
Identify all your costs: This includes direct costs, such as manufacturing, materials, labor, delivery, etc., and indirect costs, such as marketing, overheads, administration, and research and development. Make sure to consider the costs that might not be obvious, like maintenance, software subscriptions, and so on.
Break down your costs per unit: This can be tricky, but it's crucial. For example, if you run an e-commerce store, you'll need to consider not just the cost of the product, but also packaging, shipping, and handling for each individual item.
Understand your revenue: Where is your money coming from? If you sell a product or service, this might seem straightforward, but there can be more to it. Consider things like advertising revenue, commissions, and secondary products or services.
Calculating Key Metrics: Once you've got a handle on your costs and revenue, it's time to calculate your key unit economic metrics.
Customer Acquisition Cost (CAC): This is how much it costs you to acquire a new customer. It includes marketing and advertising costs, sales team salaries, and other expenses related to customer acquisition. To calculate CAC, divide the total amount spent on acquiring customers by the number of customers acquired in the same period.
Lifetime Value (LTV): This is the total revenue you can expect from a customer over the entire time they do business with you. You can calculate LTV by multiplying the average purchase value by the average number of purchases in a time period by the average customer lifespan.
Gross Margin: This is the difference between revenue and direct costs (like manufacturing and delivery), not including indirect costs like overheads. It gives you a sense of how much you're making on each unit sold, before other business costs are taken into account. To calculate gross margin, subtract the direct costs from your revenue and then divide by the revenue.
Each of these metrics gives you a piece of the unit economics puzzle.
But remember, these numbers don't exist in a vacuum. They're interconnected and should be considered together to get a full picture of your startup's financial health.
Benchmarking and Analysis: Once you have these metrics, compare them to benchmarks in your industry or against your competitors if possible. This will help you understand where you stand and which areas need improvement. Remember, unit economics isn't about achieving perfection immediately; it's about continuous improvement and profitability in the long run.
Strategize and Implement Changes: Based on your analysis, develop strategies to improve your unit economics. This could be anything from reducing production costs, improving product pricing, investing in customer retention to increase LTV, or even diversifying your revenue streams.
Continuous Monitoring and Adjustment: Unit economics isn't a "set it and forget it" aspect of your business. It's something that needs continuous monitoring and adjustment. Regularly review your metrics, keep an eye on changes in your industry, customer behavior, or your own business operations, and adjust your strategies accordingly.
By applying these principles of unit economics, startups can ensure that they're not just growing, but growing sustainably and profitably.
It can be a challenge, but with careful analysis, strategic changes, and continuous monitoring, it's definitely an achievable goal.
In the next section, we'll discuss some common pitfalls and how to avoid them.
So, keep reading!
Common Pitfalls and How to Avoid Them
While applying unit economics can be a game-changer for your startup, there are some common mistakes that can lead to incorrect conclusions or strategies. Here's a look at some of these pitfalls and how to avoid them:
Ignoring Indirect Costs: It can be tempting to focus on direct costs because they're easier to measure. However, ignoring indirect costs like marketing, administration, and overhead can paint an inaccurate picture of your unit economics. To avoid this, make sure to factor in all costs associated with your product or service, not just the obvious ones.
Overestimating Lifetime Value (LTV): Startups often fall into the trap of being overly optimistic about how long customers will stay and how much they'll spend. To avoid overestimating LTV, use conservative estimates and continuously update your figures based on real customer data.
Underestimating Customer Acquisition Cost (CAC): It's easy to underestimate how much it truly costs to acquire a customer, especially when considering long-term investments in brand and product development. Be sure to include all costs associated with attracting and converting customers, even the ones that might not seem directly related.
Neglecting to Regularly Review and Update Your Metrics: Your business is not static, and neither are your unit economics. As your business grows, evolves, and scales, your unit economics will change too. To avoid falling behind, make it a point to review and update your metrics regularly.
Not Benchmarking Against Industry Standards: While every business is unique, benchmarking your metrics against industry standards or similar businesses can provide valuable context and help identify areas for improvement. Don't operate in a bubble; use the data available to you to inform your strategies.
Not Using Unit Economics to Inform Decision Making: Finally, remember that understanding your unit economics isn't just an academic exercise. It's meant to inform decision-making, help you identify opportunities for growth, and guide your strategies. Make sure the insights you gain from your unit economics are reflected in your business decisions.
By avoiding these common pitfalls, you can make the most of unit economics and use it to guide your startup towards sustainable, profitable growth.
