If your gross margin is lower than 60-90%, you have a weaker SaaS margin than you’d want. This margin can turn away investors, which can limit the amount of capital you can raise to fund growth.

Here’s the deal. It may not be a revenue issue. It may be that you are not monitoring the right SaaS metrics. The result: you are probably spending too much. And you are probably not aware whether this reflects growth or simply overspending, thus ruining your budget and ROI.

This guide includes 12 key SaaS metrics that will help you track the right KPIs for the job. But first, a quick refresher

What Are SaaS Metrics?

SaaS metrics are quantitative indicators that help to analyze the health and performance of a Software as a Service business over time. The metrics track key performance indicators such as financial performance, user engagement, and the customer satisfaction level of a SaaS service.

This data can help your SaaS businesses make data-based decisions based on insights such as:

  • Understand how your customers interact with your product and services
  • View how much money your customers are spending on specific products or services to gauge their popularity
  • Monitor revenue
  • Track customer trends
  • Identify areas of improvement
  • Use data to optimize your business model for growth instead of going with gut feeling or guesswork

That said, here are some of the key SaaS metrics you’ll want to track:

  • Market size – It provides a sense of how large the potential for a product or service is. It also helps to determine the total revenue you may generate from its sales.
  • Monthly Active Customers – MAC measures the total number of customers who are actively using a product or service during the specific period of time.
  • Monthly Recurring Revenue (MRR) – It measures the total revenue your SaaS generates from customers on a recurring basis, such as subscriptions or memberships, over a given period of time.
  • Customer Acquisition Cost – CAC measures the total amount of money you spend to acquire a single, new customer in a given period. It includes marketing and advertising costs.
  • Customer Acquisition Cost Payback Period – CAC Payback Period is a measure of how long it takes your SaaS company to recoup its customer acquisition costs. You calculate it by dividing the customer acquisition costs by the total revenue you generate from the customer.
  • Customer Engagement Score – It’s a measure of how engaged a customer is with your SaaS product. You calculate CES by analyzing the frequency and duration of a customer’s interactions with your product and services.
  • Customer Retention Rate – CRR refers to the percentage of customers that continue to use your SaaS product over a given period.
  • Churn Rate – This is the percentage of customers that cancel their subscription within a given timeline.
  • Lifetime Customer Value (LCV) – It refers to the total amount of revenue that a customer generates for your SaaS over the entire period of their relationship with your company.
  • Contraction Rate – The metric measures the rate at which customers reduce their usage of your product or service.
  • Expansion Rate – This is a measure of the increase in MRR gained from existing customers over a specific period.
  • SaaS Cost of Goods Sold – COGS refers to the sum of all costs associated with delivering your SaaS service or product to customers. This includes hosting and infrastructure costs, software and license fees, support and customer success costs, marketing and sales costs, and any other costs associated with providing your service or product to the market.
  • Net Profit Margin – This is a measure of profitability. You calculate it by subtracting all expenses from revenue and dividing the result by your overall revenue. This measurement helps you assess how much of the revenue you retained as profit.
  • SaaS Unit Cost – This is a key SaaS metric that helps you determine how much you invest to deliver a product or service on a per unit basis. Examples include cost per customer, per product, per team, and more.

Here’s a deeper dive into each of the crucial SaaS metrics and share how to collect and make sense of them.

1. Market Size

Market sizing refers to determining the total number of potential buyers of your SaaS service or product within a specific market and the total revenue you may generate from those sales.

chart

This is not exactly a SaaS-specific metric.

However, knowing who might eventually become your customer is essential to developing a marketing plan that targets them. With a targeted marketing plan, you can optimize your customer acquisition costs, resulting in healthy margins from each customer.

Customers should be able to find value in your offering and adopt it quickly. The shorter the activation and conversion duration, the lower the customer acquisition costs can be.

2. Customer Acquisition Cost (CAC)

Customer Acquisition Cost (CAC) is the total amount you spend to gain one additional user within a specific period. This includes marketing, advertising, sales, and any other expenses you incur to acquire a new customer.

You want to keep CAC low in order to maintain a healthy margin. For SaaS companies, this upfront investment is repaid over time as recurring revenue (subscriptions or memberships).

You calculate CAC by taking the total costs of sales and marketing for the given period and dividing it by the number of new customers you gained during that period.

This is the common way to calculate CAC. But it can be problematic for several reasons:

  • The cost and effort to acquire a customer is different for each customer.
  • You cannot tell which customers are your most expensive customers to acquire, to maintain, or by how much.
  • This makes it challenging to decide on a SaaS pricing model for a specific client or service. If you do not have clear visibility of your cost per customer, you will have a hard time fighting out how to create healthy margins from each client or segment.

However, using a platform like CloudZero, you can identify, measure, and monitor the cost to serve each of your customers, enabling you to set profitable prices for your product or service.

Measure Cost Impact

CloudZero aligns cloud spend to specific customers, features, and products so you can identify cost per customer, see your most expensive customers, or even track changes to your unit cost baseline.

With this data in hand, you can make informed decisions regarding your pricing, how to price different segments, and which segments to focus more of your attention on (i.e., determine which segments are most profitable).

3. Lifetime Customer Value (LCV)

Life Customer Value (LCV) measures the value a customer provides your company from the moment they become a customer until they cancel their subscription.

4. Customer Acquisition Cost (CAC) Ratio

The CAC ratio is the ratio of the total cost of acquiring new customers over the total revenue the customers generate over their lifetime. In other words, it is the cost of gaining each new customer, divided by the total revenue that customer generates for your SaaS business.

5. LCV To CAC Ratio

The Lifetime Customer Value (LCV) to Customer Acquisition Cost (CAC) ratio is a great way to measure the success of a business model.

It helps to determine if the money spent to acquire customers is worth the long-term revenue they generate. CFOs use the LCV:CAC ratio to determine the return on investment a customer provides.

Calculate LCL:CAC by dividing a customer’s LTV by their CAC.

A good LTV:CAC ratio is often between 3-5. Lower than that and it may indicate you do not have product-market fit. A ratio above 5 indicates a need to invest more in sales and marketing. If the ratio is less than 1 then it may mean losing revenue on each customer.

6. Monthly Active Customers Vs. Users

It is common for teams to use the terms monthly users and monthly active users interchangeably. Although monthly users describe all your SaaS users per month, active customers are people who pay monthly to use your service.

Those on free trials or free plans do not count as active customers unless you use a freemium business model.

The difference is significant, as it gives you insight into how many people are using versus paying for your SaaS product. Thus, you can understand your cash flow in terms of your costs to support all customers versus the revenue you earn from them.

This metric also allows you to see if the resources you use to support all users versus paying subscribers is sustainable.

You can introduce different pricing tiers that free users can upgrade to after a specific period (limited-time trial) if you figure that you might run into cash flow trouble in the future. By doing so, these users can start generating recurring revenue to ensure profitability.

7. Monthly Recurring Revenue (MRR)

MRR is a fundamental SaaS metric because it tells you how much revenue your customers generate each month. You can calculate MRR manually, just as you can with total users and active clients. Alternatively, you can use a tool like ProfitWell to calculate it in real-time.

profitwell

You can calculate your annual run rate or annual recurring revenue (ARR) by multiplying your monthly revenue by 12.

It is also possible to use MRR to determine if you are charging enough per month to break even, become profitable, or sustain growth.

SaaS companies with a healthy MRR are self-sustaining. The rule of thumb is to ensure your revenue growth rate and profitability margin are both at least 40%. If your range is less than 40%, you may experience liquidity problems soon.

You can use ARR to plan your investment in additional features, hiring, and subscriptions such as CloudZero and ProfitWell.

8. Customer Retention Rate

In SaaS business models, retention is a vital metric. Essentially, Customer Retention Rate (CRR) measures the total number of customers you have at the beginning of a period minus the number you keep at the end.

Remember, SaaS is built on the concept of recurring revenue. The only way to earn recurring revenue is to retain your customers over a specific period. So, your recurring revenue depends on how many customers you keep each month.

9. Churn Rate

Churn is the rate at which customers leave a company over a specific period, expressed as a percentage of your total number of customers. Here’s what each churn rate means:

  • A high churn rate shows that something is wrong (either with your software, customer service, or some other aspect of your business).

Maybe a critical feature doesn’t work as well as it should. Or, perhaps a competitor has just introduced a highly sought-after feature, or lowered prices significantly, attracting your customers.

  • A low churn rate may indicate that your software provides excellent value and fits your market well.

It may also indicate that you are undervaluing your offering by charging a low subscription fee. If you have a low churn rate but a struggling cash flow, this might be the case.

What is the customer churn rate?

The customer churn rate is the percentage of customers who cancel their subscription or do not renew their contract within a given period. Many SaaS companies use it as a measure of customer dissatisfaction or loyalty to the product or service.

To calculate your monthly customer churn rate, dividing the number of canceled subscribers by the number of active subscribers 30 days ago. Multiply this result by 100 to convert it to a percentage.

Monthly customer churn rate = (Unsubscribed customers in the month/Active subscribers 30 days ago) X 100%

What is the revenue churn rate?

Revenue churn rate is a measure of the amount of subscription revenue lost in a given period. You calculate it by taking the total amount of revenue lost due to customer churn and dividing it by the total amount of revenue all customers generated during the same period.

Be sure to add the MRR of canceled subscriptions to the MRR lost to downgrades. Then divide the result by the MRR you had 30 days ago. To get your churn rate in percentage, multiply the result by 100.

Monthly revenue churn rate = ((MRR of canceled subscriptions + MRR lost to downgrades)/MRR 30 days ago) X 100%

Or, you can use a tool like Baremetrics to calculate both types of churn for your SaaS business.

baremetrics

Make sure you monitor your churn rate continuously, looking for ways to keep it under 8% per month. If not, it could erode your revenue and, ultimately, margins.

10. Contraction MRR

If you offer pricing tiers, then you know customers may sometimes downgrade to cheaper options. The contraction MRR metric helps measure this kind of scenario.

Contraction happens every time you lose MRR from an existing customer — not when they cancel their subscription. So anything that leads a customer to pay less for their monthly subscription than they usually do.

If a customer feels that they are getting enough value for a lower price, they may downgrade. Another reason could be that teams with multiple users paying per-user-per-month have reduced members. Or, customers who downgrade may feel your higher-priced plans aren’t worthwhile.

In any case, a high contraction rate hurts your MRR.

You can use The Net Promoter Score (NPS) and customer feedback to find out where the issue could be hiding.

CloudZero allows engineering teams to drill down and inspect the specific costs and services driving their product, features, and more. Group costs by feature, product, service, or account to uncover unique insights about your cloud costs that will help you answer what’s changing, why, and what you can do about it.

11. Expansion MRR

An expansion in MRR shows an increase in MRR gained from existing customers over a specific period. This can happen when a user upgrades to a higher-paying plan or subscription, as one example.

You can use expansion MRR to evaluate whether a marketing campaign or conversion optimization strategy is working.

If you have strong expansion MRR, you can counter churn when upsells and value from upgrades and upsells exceed the value you lose through cancellations.

You can calculate it manually using Net MRR, or you can use a metrics automation tool such as Klipfolio to do it for you.

12. CAC Payback Period (Months To Recover CAC)

Your CAC payback period defines how long you need a customer to stay subscribed in order to break even. Some call this metric positive cash flow.

Months to recover CAC describes the number of months a customer needs to renew their subscription before you can recover a revenue amount equal to the amount you used to gain them.

Eventually, you start to collect returns on that investment from the month you break even. This is assuming the customer renews their monthly or annual subscription consistently.

Divide your CAC by the product of MRR and Gross Margin (GM) to calculate your Months to Recover CAC.

Months to Recover CAC = CAC/MRR X GM

Note: Calculate GM by subtracting your SaaS cost of goods sold from gross revenue.

13. Customer Engagement Score (CES)

The customer engagement score (CES) helps you measure how engaged your existing customers are. This includes your free trial users. You calculate the engagement score for each user based on the actions they take or avoid over time.

These actions may include:

  • How often a user accesses your SaaS product or service
  • The key feature(s) the user engages with or not
  • A set of specific actions a user takes within an application
  • Upgrades, such as switching from a free plan or free trial to a paid plan
  • Subscription renewals
  • The number of support tickets the customer opens

You then calculate your CES by multiplying the weight of a single engagement event/action by the frequency of these actions/events to arrive at an event value. Finally, you add all event values for each customer to determine the customer engagement score.

14. SaaS Cost Of Goods Sold (COGS)

COGS is a measure of how much your SaaS company spends on serving its customers. The following are examples of SaaS COGS:

  • The cost of hosting customers’ workloads on AWS
  • Software delivery costs
  • Cost increases related to extra features or an increase in computing power
  • Expenses associated with engineering experiments, including quality assurance
  • Updates and patches for security issues

You can boost your profit margins by reducing the costs of goods sold on different product lines. This can also enable you to lower prices or increase your discount rate, a move that can help you attract more customers.

Keeping SaaS COGS low is not always a good thing. How come?

This is because reducing inputs might require tradeoffs.

Suppose your company reduces its AWS EC2 budget. The decision may limit your application’s scaling capabilities, further deteriorating its performance, availability, and overall customer experience. It may also result in user security threats.

Depending on what finance and engineering recommend, you must first decide on what tradeoffs to make or which risks to mitigate.

15. Net Profit Margin

This is the ultimate metric you want to increase even if you won’t break even in the next couple of years. Net profit heavily depends on several variables, some of which are outlined in the metrics presented here. These are all part of cloud economics for SaaS companies.

There is another metric many SaaS businesses find difficult to measure, but one that is crucial to find out if you are on track to making a profit.

16. Unit Cost

Unit cost can refer to cost per customer, per feature, per message, and even per team in the SaaS industry. This metric should help you visualize the relationship between cloud computing costs and various aspects of your business. Here are some examples:

  • What specific features of your application are the most expensive to run?
  • What features do customers actually use?
  • Are there features you can decommission without losing significant revenue?
  • Which customer is the least profitable for you?
  • How much does each transaction cost?

You can also monitor unit costs to see how changes in inputs impact outputs. What happens, for example, when you add extra features to your application?

Unit costs inform you how one area of your business, such as an engineering team or specific developers’ actions, affects your entire company’s finances.

One big problem remains. In most SaaS monitoring tools, you cannot see costs in this way or map them to the way you work. An AWS bill, for example, doesn’t provide details about what, who, or how your EC2 instances were used.
