Calculating the cost of ARR (Annual Recurring Revenue) is an important task for any business that relies on subscription-based revenue models. It helps you understand the true cost of acquiring and retaining customers, and can inform decisions around pricing, marketing, and customer retention strategies. In this article, we'll explore what the cost of ARR is, when it's valuable to calculate, and how to calculate it.
What Is Cost of ARR?
The cost of ARR is the total cost of acquiring and retaining a customer over the course of their subscription. This includes all marketing and sales expenses associated with acquiring the customer, as well as ongoing expenses related to customer support, account management, and retention efforts. By calculating the cost of ARR, you can determine the profitability of your subscription business and identify areas where you can reduce costs or increase revenue.
It's important to note that the cost of ARR is not the same as the cost of goods sold (COGS), which only includes the direct costs associated with producing and delivering a product or service. The cost of ARR is a more comprehensive measure of the true cost of doing business in a subscription model.
When Is It Valuable To Calculate Cost of ARR?
Calculating the cost of ARR is valuable for any business that relies on subscription-based revenue models, including SaaS companies, subscription box services, and membership-based organizations. It can help you understand the true cost of acquiring and retaining customers, and inform decisions around pricing, marketing, and customer retention strategies.
For example, if you find that the cost of acquiring a customer is higher than the revenue generated by their subscription, you may need to adjust your pricing or marketing strategies to improve profitability. Alternatively, if you find that the cost of retaining a customer is lower than the revenue generated by their subscription, you may want to invest more in customer retention efforts to increase customer lifetime value.
How To Calculate Cost of ARR
Calculating the cost of ARR involves adding up all the expenses associated with acquiring and retaining a customer over the course of their subscription. This can include:
- Marketing and advertising expenses
- Sales commissions and bonuses
- Customer support and account management expenses
- Retention and renewal efforts
To calculate the cost of ARR, you can use the following formula:
Cost of ARR = (Total Expenses / Number of Customers) / 12
For example, if your total expenses for acquiring and retaining customers over the course of a year are $100,000 and you have 1,000 customers, your cost of ARR would be:
($100,000 / 1,000) / 12 = $8.33 per customer per month
This means that the cost of acquiring and retaining each customer is $8.33 per month, on average.
By calculating the cost of ARR on a regular basis, you can track changes in your business's profitability and identify areas where you can reduce costs or increase revenue. This can help you make informed decisions around pricing, marketing, and customer retention strategies, and ultimately improve the overall health of your subscription business.
