Forecast Series Part 3 (of 5)
Forecasting revenue can feel overwhelming, but breaking it down into manageable parts makes it much more actionable. In our last post, we introduced the “golden equation” for ecommerce success:
This equation is the foundation for building a reliable revenue forecast. Now, let’s take it one step further by segmenting that revenue into two key groups: new customers and returning customers.
Why is this important? Because new and returning customers behave very differently, and understanding their patterns allows you to make smarter, more strategic decisions about where to invest your time and resources.
Why Returning Customers Are Your Best Bet for Predictable Revenue
Returning customers are the backbone of any successful ecommerce business, and for good reason. They already know your brand and your products, which eliminates much of the guesswork and hesitation that comes with a first-time purchase. This familiarity provides significant advantages:
- Lower Return Rates
Returning customers are more confident in their purchases because they already know what to expect. They’re familiar with your sizing, product quality, and shipping experience, leading to fewer returns and exchanges. - Lower Acquisition Costs
You’ve already paid the upfront cost to acquire these customers. Now, you can focus on low-cost retention channels like email, SMS, and loyalty programs to keep them engaged. - More Efficient Conversions
Returning customers require fewer touchpoints to convert. Unlike new customers, who may need to see your brand multiple times across various channels, returning customers are more likely to click on a reminder email or respond to a text about a sale. - Higher Lifetime Value
With returning customers, the work isn’t just about getting them to make another purchase—it’s about increasing their order frequency and average order value (AOV) over time.
Here’s a simple way to think about returning customer revenue:
Customer Count x Order Frequency x AOV = Returning Customer Revenue
For example:
If you have 5,000 returning customers who order twice a year and spend an average of $100 per order, your returning customer revenue would be:
5,000 x 2 x $100 = $1,000,000
New Customers: The Fuel for Future Growth
While returning customers provide stability, new customers are critical for growth. After all, no business can thrive on repeat customers alone—you need a steady flow of new shoppers to keep growing. But new customers present unique challenges:
- Higher Acquisition Costs
New customers don’t know your brand yet, so they’re less likely to convert without significant persuasion. This often means relying on costly acquisition channels like social media ads, non-branded Google search terms, or influencer marketing to get their attention. - More Uncertainty
New customers are less familiar with your products, which can lead to higher return rates or cart abandonment. They may also require more touchpoints, like reviews or trust signals, before feeling confident enough to purchase.
The New Customer Equation
Forecasting new customer revenue requires looking at three key variables:
Customer Count x AOV x Initial Purchase Frequency = New Customer Revenue
For example:
If you need $1,000,000 in revenue from new customers and your historical data shows an AOV of $100 and a typical new customer makes 1 purchase in their first year, you’ll need:
10,000 customers x $100 x 1 = $1,000,000
Bringing It All Together: The Gap Analysis
One of the key benefits of separating your revenue forecast into new vs. returning customers is that it helps you identify how much revenue you expect from each group. Here’s how to do it:
- Start with Your Total Revenue Goal
For example, let’s say your goal is $2,000,000. - Calculate Returning Customer Revenue
Using the example above, returning customers generate $1,000,000. - Subtract Returning Customer Revenue from Your Goal
$2,000,000 – $1,000,000 = $1,000,000 from new customers. - Use the New Customer Equation to Determine Your Targets
Based on an AOV of $100 and an initial purchase frequency of 1, you’ll need to acquire 10,000 new customers to hit your revenue goal.
This simple gap analysis helps you clearly define how many new customers you need to acquire, and it highlights the importance of retaining existing customers to keep the pressure off acquisition efforts.
What’s Next? Breaking Down the Channels
Once you’ve identified your revenue targets for new and returning customers, the next step is to figure out how to reach them. That’s where acquisition and retention channels come into play. In our next post, we’ll dive into the pros and cons of various channels—from Facebook and Google Search for new customers to email and SMS for returning customers—and how to forecast their impact on your revenue goals.
