Apr 6, 2025

As small business owners and artisans in the eco-friendly diaper industry, it's crucial to ensure that our subscription services are not only sustainable but also economically viable. Key Performance Indicators (KPIs) are essential tools for measuring the success and potential of our businesses in the artisan marketplace. In this blog post, we will explore seven industry-specific KPIs that can be used to assess the performance of eco-friendly diaper subscription services. From customer acquisition cost to churn rates, we'll delve into the unique insights that these metrics can provide, helping you make informed decisions and drive growth in your business.

Seven Core KPIs to Track

  • Subscription Renewal Rate
  • Customer Acquisition Cost
  • Compostable Diaper Usage Rate
  • Customer Retention Rate
  • Average Revenue Per User (ARPU)
  • Net Promoter Score (NPS)
  • Carbon Footprint Reduction Per Subscriber

Subscription Renewal Rate

Definition

The Subscription Renewal Rate KPI measures the percentage of customers who renew their subscription for a product or service over a specific period. This KPI is critical to measure as it provides valuable insights into customer satisfaction and loyalty. In the business context, a high subscription renewal rate indicates that customers are satisfied with the product or service and are willing to continue their ongoing commitment. It also reflects positively on the company's retention efforts and the overall customer experience. On the other hand, a low subscription renewal rate can signal potential issues with the product, customer service, or overall value proposition, which can impact the company's revenue and growth.

How To Calculate

The Subscription Renewal Rate is calculated by dividing the number of customers who renewed their subscription by the total number of customers up for renewal, and then multiplying the result by 100 to get the percentage. The numerator represents the customers who decided to extend their subscription, while the denominator includes all customers eligible for renewal within the specified time frame.

Subscription Renewal Rate = (Number of Renewed Subscriptions / Total Number of Customers up for Renewal) x 100

Example

For example, suppose Green Tot Tushies had 500 customers whose subscription was up for renewal in a given quarter. Out of those, 400 customers decided to renew their subscription. Using the formula, the Subscription Renewal Rate would be (400 / 500) x 100 = 80%. This means that 80% of the customers renewed their subscription during that period.

Benefits and Limitations

The Subscription Renewal Rate KPI is beneficial for understanding customer loyalty and satisfaction, as well as gauging the effectiveness of retention strategies. However, it may not capture the reasons behind customer decisions to renew or not renew, so it should be complemented with other customer feedback and engagement metrics for a comprehensive view.

Industry Benchmarks

According to industry benchmarks, the average subscription renewal rate for eco-friendly products and services in the US ranges between 70% to 75%, with top performers achieving rates of 80% or higher.

Tips and Tricks

  • Regularly survey customers to understand their reasons for renewing or not renewing their subscription.
  • Offer incentives or personalized offers to encourage subscription renewal.
  • Provide exceptional customer service to build long-term relationships with subscribers.
  • Monitor customer engagement and satisfaction throughout the subscription period to proactively address potential issues.

Customer Acquisition Cost

Definition

Customer Acquisition Cost (CAC) is a key performance indicator that measures the cost associated with acquiring a new customer. It is critical to measure because it provides valuable insight into the efficiency of a company's marketing and sales efforts. By understanding the CAC, businesses can assess the return on investment for their customer acquisition strategies and make informed decisions about resource allocation and budgeting. This KPI is important because it directly impacts a company's profitability and long-term growth potential. A high CAC can eat into profit margins, while a low CAC may indicate that the business is effectively attracting and converting customers at a reasonable cost.

How To Calculate

The formula for calculating Customer Acquisition Cost is the total cost of sales and marketing over a given period divided by the number of new customers acquired during that same period.

CAC = (Total Sales and Marketing Cost) / (Number of New Customers Acquired)

Example

For example, if a company spends $10,000 on sales and marketing in a month and acquires 500 new customers during that same period, the CAC would be $20 ($10,000 / 500).

Benefits and Limitations

The benefit of measuring CAC is gaining insight into the cost-effectiveness of customer acquisition efforts, which allows for strategic decision-making and efficient allocation of resources. However, a limitation is that CAC does not account for customer lifetime value, which means that a low CAC may not necessarily indicate profitable customer relationships in the long run.

Industry Benchmarks

According to industry benchmarks, the average CAC in the consumer goods sector in the US is approximately $25, with top-performing companies achieving a CAC of around $10. This indicates that efficient customer acquisition is crucial for maintaining competitive advantage and profitability in this industry.

Tips and Tricks

  • Optimize marketing channels to reduce acquisition costs
  • Focus on customer retention to maximize lifetime value and offset high CAC
  • Leverage customer referrals and word-of-mouth marketing to reduce CAC

Compostable Diaper Usage Rate

Definition

The Compostable Diaper Usage Rate KPI measures the percentage of eco-friendly diapers used by customers compared to traditional disposable diapers. This ratio is critical to measure as it provides insight into the adoption rate of sustainable diapering practices among environmentally conscious parents. In a business context, this KPI is important because it directly reflects the market demand for eco-friendly diapering solutions. Monitoring this KPI is critical for assessing the impact of the business on reducing environmental waste and understanding the preferences of the target market. It matters because it helps the business tailor its offerings to meet customer needs and trends in sustainable parenting practices.

How To Calculate

The formula for calculating the Compostable Diaper Usage Rate KPI is the total number of compostable diapers used divided by the total number of diapers used (compostable and non-compostable) multiplied by 100 to get the percentage.

Compostable Diaper Usage Rate = (Total Compostable Diapers Used / Total Diapers Used) x 100

Example

For example, if a customer used 50 compostable diapers and a total of 200 diapers in a given period, the Compostable Diaper Usage Rate would be (50 / 200) x 100 = 25%. This means that 25% of the diapers used were compostable, indicating the extent of environmentally friendly diapering practices among customers.

Benefits and Limitations

The benefit of monitoring the Compostable Diaper Usage Rate is that it provides a clear indication of the business's impact on reducing environmental waste and meeting the demand for sustainable diapering options. However, a potential limitation is that it does not account for reasons behind the usage rate, such as customer preferences, pricing, or marketing strategies.

Industry Benchmarks

According to industry benchmarks, the average Compostable Diaper Usage Rate in the US is around 20%, with environmentally conscious parents increasingly opting for eco-friendly diapering solutions. Above-average performance levels in this KPI range from 30% to 40%, while exceptional performance levels can be seen at rates of 50% or higher.

Tips and Tricks

  • Educate customers about the environmental benefits of compostable diapers through marketing materials and online content
  • Offer incentives such as loyalty programs or discounts for customers who use compostable diapers
  • Collect feedback from customers to understand their preferences and tailor offerings accordingly

Customer Retention Rate

Definition

Customer retention rate is a crucial Key Performance Indicator (KPI) that measures the percentage of customers a business has been able to retain over a specific period. This ratio is critical to measure as it directly reflects the effectiveness of a company's efforts in maintaining and nurturing its customer base. In the context of the diaper subscription service industry, a high customer retention rate is essential for building a loyal customer base and ensuring sustainable long-term growth. It is critical to measure this KPI as it impacts business performance by indicating the level of customer satisfaction, loyalty, and the overall strength of the company's brand. A high customer retention rate is indicative of a strong customer relationship and is essential for reducing customer churn and maximizing customer lifetime value.

How To Calculate

The customer retention rate is calculated using the following formula:

Customer Retention Rate = ((E-N)/S) x 100
Where: E = Number of customers at the end of the period N = Number of new customers acquired during the period S = Number of customers at the start of the period

Example

For example, if a diaper subscription service started the month with 500 customers, acquired 100 new customers during the month, and ended the month with 550 customers, the customer retention rate can be calculated as follows: Customer Retention Rate = ((550-100)/500) x 100 Customer Retention Rate = (450/500) x 100 Customer Retention Rate = 90%

Benefits and Limitations

A high customer retention rate is advantageous as it signifies customer satisfaction, loyalty, and the potential for recurring revenue. It also reduces the cost of acquiring new customers. However, it is important to note that the customer retention rate may not fully capture customer engagement or overall customer experience. Additionally, it may not account for customer referrals or other forms of positive customer advocacy that contribute to business growth.

Industry Benchmarks

According to industry benchmarks, the typical customer retention rate in the diaper subscription service industry is around 85%. Above-average performance in this KPI would be considered at a retention rate of 90% or higher. Exceptional performance would be reflected in a retention rate of 95% or above.

Tips and Tricks

  • Provide exceptional customer service to build strong relationships with customers.
  • Implement loyalty programs to incentivize repeat purchases and customer retention.
  • Solicit and act on customer feedback to continuously improve the service and meet customer needs.
  • Personalize communications and offers to strengthen the bond with customers.

Average Revenue Per User (ARPU)

Definition

Average Revenue Per User (ARPU) is a key performance indicator that measures the average amount of revenue generated from each customer or user. This ratio is critical to measure because it provides insights into the financial health and sustainability of the business. By tracking ARPU, a company can gauge the effectiveness of its pricing strategy, customer retention efforts, and overall revenue generation. Understanding ARPU is critical to business performance as it directly impacts revenue growth, profitability, and customer lifetime value.

How To Calculate

The formula for calculating ARPU is:

ARPU = Total Revenue / Number of Subscribers

Where Total Revenue represents the sum of all revenue generated during a specific period and Number of Subscribers is the total count of customers or users during the same period. Calculating ARPU provides a clear and concise indication of the average revenue generated per customer, allowing businesses to assess their pricing and customer base in relation to revenue generation.

Example

For example, if Green Tot Tushies generated a total revenue of $50,000 from 500 subscribers in a month, the calculation of ARPU would be as follows:

ARPU = $50,000 / 500 = $100

This means that the average revenue generated per user is $100 for that month.

Benefits and Limitations

The primary benefit of using ARPU is that it provides a simple, yet powerful metric for understanding revenue generation on a per customer basis. By tracking ARPU, businesses can identify opportunities to optimize pricing, improve customer retention, and enhance overall revenue performance. However, a limitation of ARPU is that it does not account for variations in customer spending behavior or acquisition costs. Therefore, it should be used in conjunction with other metrics to provide a comprehensive view of customer value.

Industry Benchmarks

According to industry benchmarks, the average ARPU for subscription-based services in the US ranges from $50 to $300 per user. Exceptional performance in the eco-friendly diaper subscription service industry may exceed $350 per user. These benchmarks reflect typical, above-average, and exceptional levels of revenue generation per user within the relevant industry.

Tips and Tricks

  • Implement tiered pricing models to encourage higher spending per user.
  • Focus on customer retention strategies to increase ARPU over time.
  • Segment customer base to identify high-value user groups for targeted marketing.

Net Promoter Score (NPS)

Definition

Net Promoter Score (NPS) is a key performance indicator that measures the loyalty of customers to a brand or company. It provides insight into customer satisfaction and their likelihood to recommend the company's products or services to others. NPS is critical to measure as it reflects the overall customer experience and their perception of the brand. This KPI is important in a business context as it directly impacts customer retention, word-of-mouth referrals, and ultimately, the company's bottom line. Understanding customer loyalty is crucial for sustainable business growth and success.

How To Calculate

The formula for calculating NPS is derived from a simple survey question that asks customers how likely they are to recommend the company to a friend or colleague on a scale of 0-10. The responses are then categorized into three groups: Promoters (score 9-10), Passives (score 7-8), and Detractors (score 0-6). The NPS is calculated by subtracting the percentage of Detractors from the percentage of Promoters. The result is a score that can range from -100 to 100, with higher positive scores indicating higher customer loyalty.

NPS = % Promoters - % Detractors

Example

For example, if out of 100 survey respondents, 60 are Promoters, 20 are Passives, and 20 are Detractors, the calculation for NPS would be: NPS = (60/100) - (20/100) = 40. This would indicate a relatively high level of customer loyalty and satisfaction.

Benefits and Limitations

The main benefit of using NPS is its simplicity and ability to provide a clear, easy-to-understand metric for customer loyalty. However, a limitation of NPS is that it only measures one aspect of customer satisfaction and does not provide actionable insights into specific areas for improvement within the business.

Industry Benchmarks

According to industry benchmarks, a typical NPS score for the subscription service industry in the US is around 30-35, while an above-average score would range from 40-55. Exceptional performers in this industry can achieve NPS scores of 60 or higher.

Tips and Tricks

  • Regularly survey customers and track changes in NPS over time to gauge the effectiveness of business initiatives.
  • Seek feedback from Detractors to understand pain points and areas for improvement.
  • Recognize and reward Promoters to encourage continued loyalty and positive word-of-mouth.

Carbon Footprint Reduction Per Subscriber

Definition

The Carbon Footprint Reduction Per Subscriber KPI measures the amount of greenhouse gas emissions that are avoided as a result of using the eco-friendly diaper subscription service. This ratio is critical to measure because it directly reflects the environmental impact of the business' operations. In the context of an eco-friendly diaper subscription service like Green Tot Tushies, reducing the carbon footprint per subscriber is crucial for demonstrating the company's commitment to environmental sustainability and resonating with their target market of environmentally conscious parents. This KPI is critical to measure as it directly impacts the business performance by showcasing the company's mission to promote eco-friendly practices and attract customers who are passionate about reducing their environmental impact through sustainable choices.

How To Calculate

The formula to calculate Carbon Footprint Reduction Per Subscriber KPI involves measuring the reduction in greenhouse gas emissions as a result of using the eco-friendly diaper service divided by the total number of subscribers. The reduction in greenhouse gas emissions is typically calculated by comparing the emissions from the production and disposal of traditional disposable diapers with the emissions from the production and disposal of the eco-friendly compostable diapers. By dividing this reduction by the total number of subscribers, the KPI provides a clear picture of the environmental impact per customer.

Write down the KPI formula here

Example

For example, if the production and disposal of traditional disposable diapers result in 500 kilograms of greenhouse gas emissions per subscriber, and the eco-friendly compostable diapers result in only 50 kilograms of greenhouse gas emissions per subscriber, the Carbon Footprint Reduction Per Subscriber would be (500 - 50) / Number of Subscribers.

Benefits and Limitations

The primary benefit of measuring the Carbon Footprint Reduction Per Subscriber KPI is that it allows Green Tot Tushies to demonstrate their positive environmental impact and attract customers who are passionate about sustainability. However, a potential limitation is that the calculation of greenhouse gas emissions can be complex and involve a degree of estimation, which may introduce some margin of error in the KPI measurement.

Industry Benchmarks

According to industry benchmarks, the average Carbon Footprint Reduction Per Subscriber for eco-friendly diaper services in the US is around 200 kilograms of greenhouse gas emissions avoided per subscriber annually. Above-average performance in this KPI would be measured at 300 kilograms or more of greenhouse gas emissions avoided per subscriber, while exceptional performance would exceed 400 kilograms of greenhouse gas emissions avoided per subscriber.

Tips and Tricks

  • Partner with environmentally conscious organizations to raise awareness about the environmental benefits of the eco-friendly diaper service.
  • Provide educational resources to customers about the environmental impact of traditional diapers versus eco-friendly options.
  • Invest in research and development to continually improve the sustainability of the diaper products and processes.
