5 B2B SaaS Metrics to Measure and Optimize

Whether you’re a new or well-established business, here are the metrics you need to track to unlock growth for your B2B SaaS.

  • Helps you figure out how much you need to spend on a prospect to convert them to a paying customer
  • Gauges the overall health of your B2B customer acquisition process

The formula for calculating CAC is as follows:

CAC = Total sales and marketing expenses / Number of new customers acquired

2. Monthly Recurring Revenue (MRR)

The Monthly Recurring Revenue metric measures how much revenue a company expects to make every month from its subscription billing data.

According to Younium, B2B SaaS companies can know the MRR metric by subscription billing data analysis and an plan their future plans.

The metric is also a reliable representation of the value of your business, thereby making it easy to secure funds to grow the business. 

The formula for calculating MRR is as follows:

3. Customer Retention Rate 

The Customer Retention Rate is a key impact metric that measures how many customers a B2B SaaS retains at the end of a given period. 

To grow your B2B SaaS, you need to retain a huge portion of the customers you acquire. Customer acquisition is very expensive and you don’t want to lose the customers you’ve worked so hard to obtain. 

Additionally, tracking the retention rate will help you understand if your product appeals to your target users.  

A high customer retention rate shows that your target users appreciate the value they derive from your product. 

Conversely, a low retention rate could indicate that there are issues with your product you need to fix right away to improve stickiness. 

The formula for calculating the customer retention rate is as follows:

Customer Retention Rate = (Customers at the end of a given period – New customers) / (Customers at the start of the period) x 100)

As mentioned in a SmallBusinessHQ resource article, a right type of CRM software can help in customer retention by helping in effective customer management.

4. Churn Rate

Churn rate or customer churn is the percentage of users a B2B SaaS loses over a given period because of account cancellations. 

According to Attrock, you can use these best subscription management software to see how many users have canceled their plans. 

B2B SaaS needs to measure the churn rate because it offers critical insights into the health of your business. A high churn rate could indicate problems with product features, customer support, or overall customer satisfaction. 

Here is the formula for calculating the churn rate:

Churn rate = (Number of customers canceling their account / Total number of customers) x 100

5. Net Promoter Score (NPS)

The Net Promoter Score is a customer satisfaction score that assesses how likely are customers to recommend your product. 

Customers are required to answer the question, “How likely are you to recommend our product to others?” on a scale of 0 – 10. They are then graded as follows:

  • Detractors: 0 – 6
  • Passives: 7 – 8
  • Promoters: 9 – 10

NPS = % of Promoters – % of Detractors
