Best SaaS Metrics Every SaaS Product Owner Must Know

Launching a successful SaaS product is not easy. In fact, many product owners believe it is almost a gamble to conceptualise an idea, launch the product, and enjoy customer appeal that translates into market success.

However, while taking this bold move might feel a lot like taking a shot in the dark, there are some SaaS metrics that matter, and can serve as valuable indicators to determine if you’re headed in the right direction. 

These SaaS valuation metrics help product owners gauge the SaaS financial health as well as paint a broader picture of the wider SaaS economics. And in this article, we’ll share them with you so that you can stop taking a shot in the dark, and instead know for sure what works and what doesn’t.

Without further ado, here are the key SaaS metrics for investors and product owners to monitor for accurate growth measurements.

Key SaaS Metrics Explained with Formulas and Practical Use Cases

This section explains the most important SaaS metrics with clear formulas and real-world use cases, helping product teams evaluate performance, improve decision-making, and build sustainable, scalable SaaS businesses.

1. Customer Churn Rate

The customer churn rate describes the percentage of your customers as a product owner who stops using your product within a specified period. With this metric, you can easily tell if your product has any product-market fit issues, weak customer successes, or any onboarding friction. Basically, it tells you if the market is accepting your product, and how well they are doing so. 

To calculate it, use:

Churn Rate = (Customers Lost During Period ÷ Customers at Start of Period) × 100.

If you’re serious about scaling, keep this number low. High churn quietly kills MRR and CLV, no matter how strong your acquisition engine is. 

2. Monthly Recurring Revenue (MRR)

SaaS companies use Monthly Recurring Revenue (MRR) as the financial metric for determining the expected revenue monthly from their customers based on their product usage. As such, many product owners use it to gauge a clear picture of growth, stability, and how aggressively they can reinvest. More specifically, tracking MRR helps product owners determine if their pricing, acquisition, and retention strategies are effective. 

To calculate it, use:

MRR = Total Number of Customers × Average Revenue Per Account (ARPA).

Some saas development companies and product owners even break MRR down into New MRR, Expansion MRR, and Churned MRR to get clearer insights on what’s working and what’s not. Clean, stable MRR often comes from a well-built, reliable product, which is the core focus of our custom software development services at Debut Infotech.

3. Average Revenue Per User (ARPU)

While the MRR provides a rather holistic view of the expected financial gains for the month, the Average Revenue Per User provides a more granular outlook by showing you exactly how much each customer brings to the business. The idea is for product owners not to just celebrate new sign-ups. Rather, with ARPU, product owners can critically examine the quality of those customers. It helps you know if the customers are choosing higher-tier plans, or the lowest packages? 

To calculate it, the formula is simple:

ARPU = Total MRR ÷ Total Number of Active Users.

You can determine whether your pricing strategy supports long-term growth or needs to be reconsidered by routinely monitoring this. Higher ARPU is frequently the result of intelligent product design, seamless onboarding, and a strong user experience—all of which are priorities at Debut Infotech.

4. Annual Contract Value (ACV)

Annual Contract Value is one of the saas metrics that matters to sales teams, product owners, and investors. They use it to determine the average annual revenue that their business realises from a single customer contract. It is often used by SaaS businesses that are focused on annual or multi-year subscription plans. This is because it gives you a clear sense of how much revenue each customer brings in over a full year. As such, Instead of guessing which customer segments are truly profitable, ACV shows you the actual long-term value you’re locking in. 

The formula is straightforward:

ACV = Total Contract Value ÷ Number of Years in the Contract.

When you track ACV consistently, you’ll notice patterns in deal size, upsell potential, and the kinds of customers worth prioritizing. Higher ACV often comes from thoughtful product strategy and polished engineering—areas Debut Infotech helps teams strengthen.

5. Daily Active Users (DAU)

Daily Active Users tells you how many people actually show up and use your product every single day. It’s one thing to have sign-ups; it’s another to have users who rely on your SaaS tool enough to return again and again. DAU gives you a pulse on engagement, stickiness, and whether your product has earned a real place in your users’ workflow. To calculate it, you simply count the number of unique users who logged in or performed a key action that day.

A healthy DAU usually signals strong UX and a smooth, dependable product experience—the kind of foundation Debut Infotech helps teams build.

6. Revenue Churn Rate

The amount of recurring revenue your SaaS company loses over a certain time frame is displayed by the revenue churn rate. Usually, cancellations, downgrades, or non-renewals are the cause of these revenue losses. Revenue churn, which is frequently the more unpleasant reality, tells you how much money was lost, whereas customer churn tells you how many users departed. This indicator will instantly show you if your higher-paying clients are departing.

To calculate it, use:

Revenue Churn Rate = (MRR Lost from Existing Customers ÷ MRR at Start of Period) × 100.
It helps you to identify weak product areas, pricing gaps, or onboarding problems.

7. Customer Retention Rate

This SaaS metric quantifies the percentage of customers retained by your SaaS product over a given period of time, especially in comparison to the total number of customers you have onboarded. More specifically, it helps you know whether your product is truly keeping customers engaged, satisfied and eager to pay. As such, it is among the most obvious indicators that your product consistently provides value.

To calculate it, use:

CRR = ((Customers at End of Period − New Customers Added) ÷ Customers at Start of Period) × 100.

8. Customer Acquisition Cost

As the name implies, the customer acquisition cost quantifies how much it costs to acquire a single paying client. It’s simple to become enthusiastic about increasing sign-ups, but CAC compels you to take a closer look. Are you effectively gaining clients, or are you overspending to keep the pipeline full?

To calculate it, use:

CAC = Total Sales and Marketing Spend ÷ Number of New Customers Acquired.

As a product owner, you should know that regular CAC monitoring helps you determine whether your acquisition plan is viable or needs to be reconsidered while giving you a better understanding of your SaaS financial health. 

9. Customer Lifetime Value

The customer lifetime value is one of the key saas metrics for investors​ looking to get an idea of the overall revenue a client is anticipated to produce during the time they use your product. CLV indicates whether the consumers are actually worth the investment, whereas CAC informs you how much it costs to get them. This statistic forces you to consider the long term issues related to your product’s sustainability. You get to ask questions like: are consumers staying, upgrading, and finding enough value to warrant your acquisition expenditures?

To calculate it, use:

CLV = Average Revenue Per User × Average Customer Lifespan.

As such, when this metric increases, it typically indicates that your product experience is good, onboarding is easy, and customers feel supported.

10. Revenue Retention

You can determine how much of your recurring revenue you effectively keep from current clients over a predetermined time frame by using revenue retention. Revenue retention informs you how much value those customers continued to produce, whereas customer retention tells you who stayed. To comprehend product stickiness, the effects of upgrades or downgrades, and overall income stability, the majority of SaaS founders rely on this statistic.

To calculate it, the common formula is:

Revenue Retention = (Revenue from Existing Customers at End of Period ÷ Revenue from Existing Customers at Start of Period) × 100.

Furthermore, with revenue retention, you can usually tell is a product has strong product value, careful pricing, and a smooth user experience.

11. Average Variable Cost (AVC)

Average Variable Cost might not be the first SaaS metric you think about, but it quietly shapes how profitable your product can become, especially as your user base grows. Think of AVC as the cost that rises or falls depending on how many customers you’re serving. Maybe it’s server usage, third-party API fees, or support hours. These aren’t fixed—they scale with activity.

To calculate it, use:

AVC = Total Variable Costs ÷ Number of Active Customers (or Units of Usage).

When you understand this number, you get clearer about your margins, pricing decisions, and how efficiently your product scales. And yes, smart architecture and optimization—something we obsess over at Debut Infotech—can help keep these costs under control.

12. LTV/CAC Ratio

The LTV/CAC Ratio shows you how the lifetime value of a customer compares to what you spent to acquire them. In other words, it helps you see if you’re creating value or unintentionally destroying it. If the ratio is below 1.0, you’re losing money on every customer. Anything above 1.0 means you’re heading in the right direction, but most SaaS leaders aim for something closer to 3.0—though that number isn’t a hard rule.

To calculate it, use:
LTV/CAC Ratio = LTV ÷ CAC

This ratio is crucial for understanding your growth efficiency and refining your acquisition strategy.

13. Lead-to-Customer Conversion Rate

Lead-to-customer conversion rate shows you the percentage of leads that eventually become paying customers. It’s one of those metrics that instantly tells you whether your marketing and sales efforts are actually producing revenue—not just traffic or sign-ups. To calculate it, use:

(Number of New Customers ÷ Total Leads Generated) × 100.

In SaaS, freemium models often convert around 5%, while stronger-performing companies sit closer to 10–15%.

When this rate dips, it usually signals weak targeting, unclear messaging, or friction in your sales funnel. Breaking it down by source helps you pinpoint the channels worth scaling and the ones draining your budget.

14. Gross Margin

Gross Margin tells you how much profit your SaaS business keeps after covering the direct costs of delivering your product—things like hosting fees, third-party APIs, or customer support tied to usage. A strong gross margin gives you room to reinvest in product development, marketing, and customer success without constantly feeling squeezed. To calculate it, use:

Gross Margin = [(Total Revenue − Cost of Goods Sold) ÷ Total Revenue] × 100.

Healthy SaaS companies often see margins between 70% and 90%, depending on infrastructure costs. If yours is lagging, it may be a sign to optimize architecture or refine your cost structure—work Debut Infotech regularly supports for scaling teams.

15. Win Rate

In the SaaS world, your win rate tells you how effective your sales team is at closing deals once a prospect becomes a qualified opportunity. Think of it as your sales “batting average.” It shows how often your team turns real pipeline opportunities into closed-won customers—something every SaaS founder should keep an eye on. To calculate it, use:

Win Rate = (Closed-Won Deals ÷ Total Qualified Opportunities) × 100.

Most SaaS teams sit around a 22% win rate, while top performers hit 35% or more. Tracking this metric helps you understand whether your sales process is dialed in or needs refinement to boost conversions.

16. Revenue Per Lead

Revenue Per Lead helps you understand the actual monetary value each lead brings into your SaaS business. Instead of just tracking how many leads enter your funnel, this metric shows you whether those leads are worth the effort and spend. It ties marketing performance directly to revenue, giving you a clearer view of which channels bring in high-value prospects and which ones drain your budget. To calculate it, use:

RPL = Total Revenue Generated ÷ Total Number of Leads.

When this number rises, it usually means your targeting is sharper and your funnel is attracting people who genuinely need your product—insights every SaaS founder can use to scale smarter.

17. Net Promoter Score

The Net Promoter Score tells you a lot about your SaaS product’s customer loyalty. This SaaS metric was developed to help product owners answer the critical question: “How likely are you to recommend our product to a friend or colleague?” 

So, why should SaaS product owners care about the NPS? 

It’s one of the key SaaS metrics for investors because it lets both investors and product owners a clear signal of customer satisfaction, potential churn risks, and how a particular product stacks up against the competition. More importantly, you should know that having a strong NPS means your product is more likely to enjoy more referrals, retain customers for longer, and experience seamless organic growth. It may seem very straightforward, but it is still a powerful tool for guiding product improvements and strengthening long-term loyalty.

Conclusion

It’s okay to take a bold step with your idea as you enter the market. What’s not okay is to keep navigating the market without gauging how well your product is doing. 

With the key SaaS valuation metrics we have discussed so far every product owner or investor must be able to get a holistic view of how well their product is performing.
