The subscription billing model is a powerful tool for many companies to generate stable revenue. However, to ensure sustained profitability, simply providing a service isn’t enough. Businesses need to properly manage and improve metrics such as customer lifetime value (CLV) and churn rate.

In this article, we’ll discuss the basic revenue model of subscription businesses, as well as the key metrics that influence revenue and practical strategies for maximizing profits.

Key takeaways

• The subscription business model is designed to generate ongoing profits by having customers pay a fixed monthly fee in exchange for the right to use a service.
  
• It’s important to treat the basic profit formula for subscriptions merely as a reference for understanding the big picture.
  
• Four key metrics that determine the success of a subscription business are customer lifetime value (CLV), customer acquisition cost (CAC), churn rate, and monthly recurring revenue (MRR).
  
• To increase profits in a subscription business, you need to implement multiple strategies.
  
• With Stripe Billing, you can seamlessly manage all aspects of a subscription service, such as setting up monthly billing and creating multiple plans.
  

How subscription models generate profit

In Japan, the subscription business model is also referred to as an “ongoing purchase” or a “periodic purchase.” A key characteristic of this model—as seen in services that distribute digital content such as videos, music, and e-books—is that it focuses primarily on the right to experience and use the service itself.

In other words, rather than selling products or services outright, this model generates ongoing revenue by having customers pay a fixed monthly fee for the right to use a service over a set period of time.

Therefore, with a subscription model, businesses can maintain long-term relationships with customers and build a stable revenue base by providing ongoing services. In recent years, particularly alongside the rapid expansion of Japan’s subscription market, establishing a robust system for revenue management has become a top priority.

How subscription models differ from one-time purchase models

With a one-time purchase business model, where a transaction is completed with a single payment, revenue tends to fluctuate over time based on factors such as seasonal events. It’s therefore generally considered more difficult to stabilize revenue with a one-time purchase model than with a subscription model.

Unlike one-time purchase models, subscription models are based on the premise of building long-term relationships with customers. As a result, subscription businesses benefit from the ability to more easily forecast revenue and achieve stable cash flow.

Basic profit formula

The basic formula for understanding the profit structure of a subscription business is as follows:

• Profit = Number of Customers × (Monthly Subscription Fee - Operating Cost per Customer) - Customer Acquisition Cost
  

However, this is a simplified calculation, so it should be used only as a general reference.

While customer acquisition cost (CAC) is a one-time cost incurred when acquiring a new customer, profit is evaluated over a specific period. Therefore, you must first standardize the time periods used in the calculation, whether that’s months or years, before performing the calculation.

As such, when managing the finances of a subscription business, it’s important not to judge profitability based solely on a single period or simple revenue and expense calculations, but rather to analyze the business by combining appropriate subscription KPIs (key performance indicators) tailored to your objectives.

Four metrics that determine subscription business profitability

Let’s look at four metrics that influence the profitability of subscription businesses. Properly measuring and monitoring these metrics is key to achieving sustainable business growth.

CLV: The longer the subscription period, the higher the profit

Customer lifetime value (CLV) refers to the profit generated from a single customer over the entire duration of the relationship, from start to finish. The longer a customer uses the service, the more the total profit per customer accumulates, allowing you to maximize profitability.

CAC: Are you recouping the costs of customer acquisition?

Customer acquisition cost (CAC) refers to the total cost incurred to acquire one new customer.

Acquiring new customers is integral to the subscription business. CAC is a key metric for measuring the cost effectiveness of customer acquisition expenses, such as those for advertising and sales. If the revenue generated from a customer exceeds the CAC, it indicates that you’re achieving a sufficient return on your investment.

Churn rate: Minimizing the impact on CLV

The churn rate refers to the rate at which customers cancel their subscriptions. To ensure the success of a subscription business, it’s important to keep the churn rate as low as possible. If customer retention periods become shorter due to cancellations, CLV will decline, ultimately leading to a decrease in future revenue. Therefore, if your churn rate is high, it’s important to promptly identify the cause and implement corrective measures.

MRR: Tracking monthly revenue trends

Monthly recurring revenue (MRR) refers to revenue generated on a repeat basis each month. MRR is a key metric for assessing the stability and growth potential of a subscription business. By tracking revenue trends on a monthly basis, you can accurately compare and analyze monthly performance, growth rates, and seasonal fluctuations.

Practical strategies for increasing subscription revenue

To maximize revenue in a subscription business, it’s important to implement concrete strategies based on KPIs.

Minimize churn by reducing unintended cancellations

There are two types of churn: cancellations initiated by the customer (i.e., voluntary churn) and unintended cancellations (i.e., involuntary churn) caused by issues such as failed payments. An effective way to safeguard against unintended cancellations is to implement a payment system equipped with features such as card information update notifications and automatic payment retries. This helps mitigate the risk of revenue loss due to customer churn.

Increase CLV through annual plans and upselling

Effective ways to grow subscription revenue include actively promoting annual plans and engaging in upselling or cross-selling to higher-tier plans with more features. By combining these strategies, you can further increase CLV and strengthen revenue stability.

Optimize price structures through tiered pricing and usage-based billing

Another effective strategy for increasing subscription revenue is a tiered pricing structure; this involves lowering the barrier to entry with free or low-cost plans while encouraging users to upgrade to higher-tier plans as their usage frequency and needs grow.

Furthermore, for products where costs fluctuate based on usage—such as AI or SaaS solutions—adopting a hybrid model that combines flat-rate billing with usage-based billing can help optimize revenue.

Design a customer experience that minimizes churn

By offering customers who request cancellation options such as a temporary pause, a plan downgrade, or an adjustment of usage frequency, you can potentially retain them before they complete cancellation. Offering such alternative solutions can have a significant impact on long-term customer retention.

Minimize CAC and shorten the payback period

To improve profitability, it’s important to understand the CAC for each advertising and sales channel and to re-evaluate strategies for unprofitable channels where the payback period is excessively long.

By regularly analyzing the cost-effectiveness of each strategy and concentrating investments on the most efficient payback routes, you can achieve stable cash flow.
