Should You Switch to Usage-Based Billing? Calculate Your ROI First
Bas de GoeiDid you know that the SaaS market has experienced a compound annual growth rate of 25% over the past decade? This impressive growth has been fueled by rapid changes in industry competition, product demand, and the continuous evolution of business models, creating a wealth of new market opportunities.
In SaaS, growth metrics are your compass, guiding you toward sustainable success. These key performance indicators (KPIs) provide critical insights into your business's health, helping you track progress and make data-driven decisions that fuel growth.
In this post, you'll learn:
Let’s begin by explaining what SaaS growth metrics truly are.
SaaS growth metrics are quantifiable measures of your company's performance, specifically concerning its growth over a defined period. Think of them as your key performance indicators (KPIs) that provide key insights into the health and trajectory of your SaaS business.
Growth metrics go beyond basic financial reporting; they delve into various aspects of your business, from revenue generation and customer acquisition to user engagement and customer satisfaction.
SaaS metrics are tailored to the unique characteristics of the SaaS model, such as recurring revenue streams, customer churn, and lifetime value. Instead of simply looking at one-time sales, SaaS metrics help you understand the long-term health of your customer relationships and the effectiveness of your growth strategies.
Choosing the right growth metrics is critical for scaling your SaaS business efficiently. By focusing on the metrics that truly matter, you can identify areas for improvement, optimize your strategies, and make data-driven decisions that fuel sustainable growth.
Next, we'll be analyzing 25+ growth metrics for SaaS in more detail, starting with those focused on revenue.
In SaaS, revenue is about building recurring streams of revenue that fuel sustainable growth. That's why revenue metrics are so vital. They provide a clear picture of your financial health, allowing you to track your progress, spot areas for improvement, and make informed decisions that drive long-term success.
Let's dive into some of the most crucial revenue metrics for SaaS:
ARR is the lifeblood of any SaaS business. It represents the predictable, recurring revenue generated from your subscriptions over a year. ARR provides a snapshot of your current revenue performance and serves as a foundation for forecasting future growth.
ARR = Sum of all recurring subscription revenue within a year
Example: If you have 100 customers, each paying $100 per month for an annual subscription, your ARR would be $120,000 (100 customers x $100/month x 12 months).
Expansion revenue measures the growth of your existing customer base. This metric includes upgrades, cross-sells, and add-ons. A healthy expansion revenue rate indicates that you're effectively providing value to your customers and encouraging them to spend more.
Expansion Revenue Rate = (Expansion Revenue / Starting MRR) x 100
Example: If your starting MRR is $50,000 and you generate $10,000 in expansion revenue, your expansion revenue rate is 20%.
NRR provides a holistic view of your revenue retention by considering all revenue streams from your existing customers, including expansion revenue and churn. NRR above 100% indicates that you're growing revenue from your existing customer base, even after accounting for churn.
NRR = [(Starting MRR + Expansion MRR - Churned MRR) / Starting MRR] x 100
Example: If your starting MRR is $100,000, then you gain $20,000 in expansion MRR, and you lose $10,000 in churned MRR, your NRR is 110%.
Gross revenue churn measures the percentage of recurring revenue lost due to customers canceling or downgrading their subscriptions. Keeping a close eye on your churn rate is crucial for pinpointing potential problems and taking corrective action.
Gross Revenue Churn Rate = (Churned MRR / Starting MRR) x 100
Example: If your starting MRR is $50,000 and you lose $5,000 in churned MRR, your gross revenue churn rate is 10%.
ARPU is the average revenue generated per user or customer account within a specific period. ARPU helps you understand the revenue potential of your customer base and identify opportunities to increase monetization.
ARPU = Total Revenue / Total Number of Customers
Example: If your total revenue is $100,000 and you have 200 customers, your ARPU is $500.
LTV is a prediction of the total revenue you can expect to generate from a single customer throughout their entire relationship with your company. Understanding LTV helps you make informed decisions about customer acquisition costs and retention strategies.
LTV = ARPU x Average Customer Lifespan
Example: If your ARPU is $500 and your average customer lifespan is 3 years, then your LTV is $1,500.
This metric tracks the month-over-month or year-over-year growth of your recurring revenue. It's a key indicator of the overall health and trajectory of your SaaS business.
Recurring Revenue Growth Rate = [(Current Period MRR - Previous Period MRR) / Previous Period MRR] x 100
Example: If your MRR this month is $60,000 and your MRR last month was $50,000, your recurring revenue growth rate is 20%.

Now, let’s move on to the category of metrics to track sales growth.
Sales growth metrics are your compass for navigating the path to customer acquisition, strong retention, and increased revenue generation.
Growth metrics in this category help you understand how effectively you're attracting new customers, converting them into paying users, and maximizing the value of each customer relationship.
Let's explore some of the most important sales growth metrics for SaaS companies.
CAC is a critical metric that tells you how much it costs to acquire a new customer. It encompasses all the expenses related to sales and marketing efforts, including advertising, salaries, and software. Keeping CAC in check is fundamental for ensuring profitability and making informed decisions about your sales and marketing investments.
CAC = Total Sales and Marketing Costs / Number of New Customers Acquired
Example: If you spend $10,000 on sales and marketing in a month and acquire 100 new customers, then your CAC is $100.
The CAC payback period measures how long it takes to recoup the cost of acquiring a customer. A shorter payback period indicates a more efficient sales process and a faster return on investment.
CAC Payback Period = CAC / (ARPU - Customer Servicing Costs)
Example: If your CAC is $100, your ARPU is $150, and your customer servicing costs are $20, then your CAC payback period is 8 months.
Your lead conversion rate measures how effectively you're converting leads into paying customers. It's a key indicator of the success of your sales and marketing funnel.
Lead Conversion Rate = (Number of Customers Acquired / Number of Leads) x 100
Example: If you generate 1,000 leads and acquire 100 new customers, then your lead conversion rate is 10%.
Sales pipeline velocity measures how quickly deals move through your sales pipeline. A higher velocity indicates a more efficient sales process and faster revenue generation.
Sales Pipeline Velocity = (Number of Deals x Average Deal Value x Win Rate) / Sales Cycle Length
Example: If you have 50 deals in your pipeline with an average deal value of $1,000, a win rate of 20%, and a sales cycle length of 60 days, then your sales pipeline velocity is $166.67 per day.
ACV represents the average value of your customer contracts. It's a helpful metric for understanding the revenue potential of your customer base and tracking changes in deal sizes over time.
ACV = Total Contract Value / Number of Contracts
Example: If you close 10 contracts with a total value of $100,000, then your ACV is $10,000.
The next category of metrics is about long-term growth by tracking more customer-focused data.
Customer success is the engine that drives long-term revenue growth in SaaS. It's about making sure they achieve their desired outcomes with your product and remain loyal, engaged users.
Growth metrics focused on customer success provide valuable insights into customer satisfaction, engagement, and overall health. Let's take a closer look at some of the key metrics in this category.
Customer churn is the rate at which your customers cancel their subscriptions. It's a crucial metric for understanding customer satisfaction and identifying potential problems with your product or service. A high churn rate can significantly impact your revenue and profitability.
Customer Churn Rate = (Number of Churned Customers / Total Number of Customers at the Start of the Period) x 100
Example: If you start with 100 customers and lose 10 customers during the month, then your customer churn rate is 10%.
NPS measures customer loyalty and satisfaction by asking how likely they are to recommend your product or service to others. It's a valuable metric for gauging customer sentiment and identifying potential advocates or detractors.
NPS = % of Promoters - % of Detractors
Example: If 60% of your customers are promoters, 20% are passives, and 20% are detractors, then your NPS is 40.
CSAT measures how satisfied customers are with your SaaS product or specific interactions. It's typically measured through surveys and provides direct feedback on customer experience.
CSAT = (Number of Satisfied Customers / Total Number of Customers Surveyed) x 100
Example: If you survey 100 customers and 80 express satisfaction, then your CSAT score is 80%.
CES measures how easy it is for customers to interact with your company and resolve issues. A lower CES indicates a smoother customer experience and reduced friction.
While there isn’t a formula really, CES is typically measured on a scale (e.g., 1-5 or 1-7), with lower scores indicating less effort.
Example: A CES score of 1 might represent "very easy," while a score of 5 might represent "very difficult."
A customer health score is a composite metric that combines various data points to assess the overall health and likelihood of success for each customer. It can include factors like product usage, engagement, support tickets, and customer feedback.
The formula typically involves assigning weights to different factors and combining them to create an overall score. The specific factors and weights will vary depending on your business and the characteristics that indicate customer health.
Example:
Let's say you determine these factors are important for customer health:
You could then create a formula like this:
Customer Health Score = (0.4 x Product Usage Score) + (0.3 x Engagement Score) + (0.2 x Support Ticket Score) + (0.1 x Customer Feedback Score)
Each factor would have its own scoring system. For example, product usage could be scored on a scale of 1-10 based on login frequency, while support tickets could be scored inversely (higher score for fewer tickets).
By adjusting the weights and scoring systems, you can tailor the customer health score to reflect the factors that are most important for your business.
Analyzing retention rates by cohort involves grouping users based on shared traits (e.g., sign-up date or acquisition channel) and tracking their retentionover time. It helps identify trends and patterns in customer behavior and optimize retention strategies for different customer segments.
Retention Rate = (Number of Customers Retained in a Cohort / Total Number of Customers in that Cohort at the Start of the Period) x 100
Example: If you have a cohort of 100 customers who signed up in January and 80 of them are still customers in February, then your retention rate for that cohort is 80%.
Now, if you want to focus more on product development, then this next category of data tracking is best for you.
Product growth metrics offer insights into how users interact with your product, from initial adoption to ongoing engagement and satisfaction. These metrics help you understand what's working well, identify areas for improvement, and ultimately drive product-led growth.
Metric development in this area often involves tracking user behavior, feature usage, and feedback to measure the success of your product strategy. Let's explore some of the most important product growth metrics for a SaaS business.
DAU measures the number of unique users who interact with your product daily. It's a key indicator of user engagement and product stickiness. Tracking DAU helps you understand how frequently users rely on your product and identify trends in usage patterns.
There isn’t an actual formula. DAU is simply the count of unique users who interact with your product on a given day.
Example: If 1,000 different users log in to your application on a particular day, your DAU for that day is 1,000. Comparing your scores over time will show you when users were most active.
The DAU/MAU ratio compares your daily active users to your monthly active users. It provides a measure of user stickiness and the frequency of product usage within a month.
DAU/MAU Ratio = DAU / MAU
Example: If your DAU is 1,000 and your MAU is 5,000, then your DAU/MAU ratio is 20%, indicating that, on average, 20% of your monthly active users engage with your product daily.
Feature adoption rate measures how quickly and widely users adopt new or existing features within your product. It's a valuable metric for understanding the value and usability of your features and identifying areas for improvement.
Feature Adoption Rate = (Number of Users Who Adopted a Feature / Total Number of Users) x 100
Example: If you release a new feature and 500 out of your 1,000 users adopt it, then your feature adoption rate is 50%.
TTFV measures the time it takes for a new user to experience the core value of your product. A shorter TTFV indicates a more effective onboarding process and faster user activation.
Again, there isn’t really a formula for this metric. TTFV is typically measured in units of time (e.g., hours, days) from the user's initial signup.
Example: If it takes a new user, on average, 2 days to successfully complete a key task that demonstrates the core value of your product, your TTFV is 2 days.
Similar to cohort analysis for overall retention, you can track retention rates for features. This helps you understand which features are most engaging and contribute to user retention.
Retention Rate by Feature = (Number of Users Who Continue to Use a Feature / Total Number of Users Who Adopted the Feature) x 100
Example: If 100 users adopted a new feature and 80 of them continue to use it after a month, then your retention rate for that feature is 80%.
Average session length gauges the average duration of a user's session within your product. Longer session lengths often indicate higher user engagement and signal users are overall happy with how your solution is performing.
Average Session Length = Total Time Spent by All Users / Number of Sessions
Example: If users across all sessions spend a total of 10,000 minutes in your product and there were 500 sessions, then your average session length is 20 minutes.
The next very important category of metrics to remember has to do with all of your maintenance fees to run the business.
Operational metrics provide a window into the sustainability of your SaaS company. These metrics go beyond revenue and customer growth to assess how effectively you're utilizing resources and managing costs.
Growth metrics in this category are paramount for making 100% sure your business operates smoothly and remains financially healthy in the long run. Let's dive into some of the most important operational metrics for a SaaS company.
Burn rate measures how quickly your startup is spending its available cash. It's a vital metric for understanding your runway — how long you can operate before needing additional funding. Monitoring your burn rate helps you make informed decisions about spending, investment, and fundraising.
Burn Rate = (Starting Cash Balance - Ending Cash Balance) / Number of Months in the Period
Example: If you start with $1,000,000 in cash and have $800,000 remaining after three months, then your burn rate is $66,667 per month.
Gross margin is the difference between your revenue and the cost of goods sold (COGS), expressed as a percentage of revenue. It reflects your profitability after accounting for the direct costs associated with delivering your product or service. Healthy gross margins are fundamental for reinvesting in growth and ensuring long-term sustainability.
Gross Margin = (Revenue - COGS) / Revenue x 100
Example: If your revenue is $1,000,000 and your COGS is $400,000, then your gross margin is 60%.
RPE measures the revenue generated per employee. It's a key indicator of your team's productivity and the efficiency of your operations. Higher RPE generally suggests that your team is effectively contributing to revenue generation.
RPE = Total Revenue / Number of Employees
Example: If your total revenue is $1,000,000 and you have 50 employees, then your RPE is $20,000.
As your SaaS company matures, it's time to shift your focus to optimizing performance and achieving sustainable growth. This involves exploring more advanced metrics that provide deeper insights into your business operations.
Let's explore some of these advanced metrics.
The magic number gauges the efficiency of your sales and marketing spend in generating revenue growth. It helps you understand how effectively you're converting investments into revenue.
Magic Number = (Current Quarter Revenue - Previous Quarter Revenue) / Previous Quarter Sales and Marketing Spend
Example: If your revenue this quarter is $1,200,000, your revenue last quarter was $1,000,000, and your sales and marketing spend last quarter was $200,000, then your Magic Number is 1.0.
Note: A Magic Number of 1.0 or higher generally indicates efficient spending, while a lower number suggests that you might need to re-evaluate your sales and marketing strategies.
TTV measures the time it takes for a customer to realize the value of your SaaS product. It encompasses the entire customer journey, from initial awareness to achieving their desired outcomes.
TTV is typically measured in units of time (e.g., days, weeks, months) from the customer's first interaction with your company.
Example: If it takes a customer, on average, 4 weeks from their initial contact to successfully implement your product and achieve their desired results, your TTV is 4 weeks. A shorter TTV indicates a better customer journey and faster value realization — all leading to happier, returning customers.
Implementing and tracking the right growth metrics is an ongoing process that requires careful planning and execution. Here are some best practices to guide you:
Tracking and analyzing your SaaS growth metrics doesn't have to be a daunting task. Several powerful tools can simplify the process, providing valuable insights and saving you time. Here are a few popular options:
