Understanding CAC Payback Period for eCommerce & CPG Startups

The Customer Acquisition Cost (CAC) payback period is defined as the period of time it takes for a business to recoup the cost of earning a new customer. It’s an important metric for startups to monitor, especially CPG and eComm startups, because it gives them an idea of how efficiently and effectively they operate and generate ROI.

Generally, the shorter the CAC payback period, the better for your business model and your bottom line. A long CAC payback period could indicate a poor retention strategy and strain your startup’s finances and overall business model.

In this post, we’ll help you understand the importance of the CAC payback period and the relationship it often has with your startup’s profitability and growth. We’ll also cover how to calculate this metric, strategies to improve it and more. Read on to learn more or contact Graphite Financial today.

What is the CAC Payback Period?

Simply put, the CAC payback period measures the time that’s needed to recover the cost of acquiring a customer. This includes all the customer acquisition costs that your startup has to spend to earn business. Just think of CAC expenses as the cost of doing business. CAC can help a startup measure its overall business health and influence how investors view it.

Common expenses include advertising spend, creative development and commissions. CAC costs may also consist of employee salaries, production costs, product costs and inventory management expenses.

So why are eComm and CPG startups uniquely challenged when it comes to their CAC payback periods? It’s because of the array of challenges they face, notably:

• Intense competition
• Lofty customer expectations
• Difficulty managing logistics
• Customer service challenges
• High churn rates.

All of these factors can make it more difficult to earn a shorter CAC payback period.

Why CAC Payback Period Matters for eCommerce and CPG Startups

CAC is important for many reasons. Not only does it help measure the cost of doing business, but it can help a startup refine its pricing strategies and marketing spending. Some analysts say that it’s the single best metric for measuring the efficiency of any startup’s go-to-market process.

Your startup’s CAC payback period can also tell you a lot about your cash flow. For instance, if you have a short CAC payback period, then you are likely to have a healthier overall cash flow. That’s because a shorter CAC payback period is indicative of your startup covering its customer acquisition costs more quickly. A long CAC payback period and the opposite is likely true when it comes to your cash flow.

As a startup, refining your CAC payback period metric helps you evaluate the performance of different paying customer groups. This allows you to identify which segments require the most effort and investment to acquire.

How to Calculate the CAC Payback Period

The CAC payback period isn’t a difficult metric to calculate. Here’s the formula:

• CAC Payback Period = Customer Acquisition Cost / (Revenue – Cost of Service)

Depending on the type of startup you’re operating, CPG companies could see CAC payback periods anywhere from three to 12 months. For instance, a CPG startup selling snacks or everyday items will likely see a shorter CAC payback period due to repeat purchases and lower overall acquisition costs. Premium CPG brands often have a longer CAC payback period. This is due to higher upfront investments in targeted marketing and branding to position themselves as premium and attract niche audiences. Accurate CAC calculations are especially critical for these brands, as higher acquisition costs magnify the impact of errors, directly affecting profitability and growth strategies.

To accurately calculate the CAC payback period requires precise and reliable data. For eComm and CPG startups, monthly recurring revenue (MRR) and gross margin are two of the most important metrics to know.

Benchmarks for CAC Payback Period in eCommerce and CPG

CPG startups tend to have shorter overall payback periods usually due to factors such as lower churn rates, while eComm startups tend to have longer CAC payback periods due to the impact of their gross margins and other factors that can impact these periods.

However, several other factors can influence these benchmarks. These include:

• Market trends: Supply and demand, the economy, geopolitical events and more factors can all influence market trends.
• Customer retention: The better your startup can retain its customers acquired, the shorter the payback period.
• Customer lifetime value: If your startup has a high customer LTV, a longer CAC payback period isn’t necessarily a bad thing. It’s indicative of your average customer generating more revenue over time.
• Competition: If you’re in a competitive market, customers may shop around and retention may suffer.

Strategies to Reduce CAC Payback Period

Looking to reduce your startup’s CAC payback period? Here’s a look at some strategies worth considering:

Pricing Strategies

One strategy to improve your customer retention rate is to play around with various pricing strategies. For instance, you might offer subscriptions versus customers making one-off purchases. Another idea is to offer pricing tiers that offer benefits. For example, some eComm brands offer discounts for registering for auto distribution on certain products. Under this model, they’ll automatically be sent the same product about the time they expect to run out of their current supply. Adjust your pricing to see if you can incentivize purchasing. Refining your customer acquisition strategy can also help to attract more customers efficiently, leading to a faster CAC payback period.

Targeted Marketing

Marketing is so important to your CAC payback period. It’s important to identify your market and market to this audience accordingly so that you’re reaching the audience segment that can provide the greatest value. Some good targeted strategies include geographic targeting and targeting efforts based on consumer behavior. By focusing your sales and marketing efforts on these high-value segments, you can reduce acquisition costs and improve your overall CAC payback period.

Upselling and Cross-Selling

Startups can grow their revenue without having to earn new customers by upselling and cross-selling to their existing customers. You may even be able to offer discounts on additional purchases to further incentivize your customers into upselling and cross-selling activities.

Other Strategies

Other strategies for reducing the CAC payback period may include analyzing your startup’s churn rate, incorporating data into your decision-making processes and using customer referrals to help organically grow your customer base.

Common Pitfalls to Avoid When Optimizing CAC Payback

Some common pain points you’ll want to make sure to avoid when it comes to optimizing CAC payback include:

• Failing to analyze paid advertising efforts. It’s important to carefully analyze these efforts so you know the full ROI and can adjust accordingly.
• Ignoring churn rate: The churn rate is the percentage rate of when customers stop doing business with you. The higher the churn rate, the worse off it usually is for your startup.
• Misinterpreting data or using incorrect formulas.
• Not tracking marketing expenses effectively, which can lead to overspending and an inefficient CAC payback period.

How CAC Payback Differs From LTV: CAC Ratio

The LTV: CAC ratio stands for Customer Lifetime Value to Customer Acquisition Cost. It’s a metric that compares the value of a customer over their lifetime versus the cost of acquiring them. Generally, you want this metric to be around 3:1, which means a customer will bring in approximately three times the cost to acquire them.

The LTV: CAC ratio helps indicate profitability and helps measure how effectively and efficiently your startup is achieving it. It’s also commonly used to predict future growth, but is subject to change based on several factors.

Why CAC Payback Period Is Vital for Startups

The CAC payback period is essentially the cost of doing business for your startup – and that’s why it’s so important. Understanding and optimizing the CAC payback period is critical to maintaining a favorable cash flow and driving sustainable growth.
