NRR – What is it and why is it important for SaaS?

If you’re coming from the world of software, you are likely well aware that retaining your customers is much more profitable than paying to acquire new ones.


That’s because the cost of customer acquisition tends to increase rapidly. Instead, to better grow your business, you need to focus on making your active customers more profitable and longer-lasting.


As basic as that may seem, many SaaS companies tend to analyze their business through the perspective of MRR or ARR (Monthly and Annual Recurring Revenue) and sales velocity, forgetting about NRR (Net Revenue Retention), which can provide an even better long-term view of the company.


Why is that important?


Imagine a chicken trying to fly—it may get a little airtime but it won’t go very far. Just like the chicken, a company that has a growing MRR through new sales and customer acquisition efforts but a low CLTV (Customer Lifetime Value) is in for a short flight.


In other words, if your churn isn’t under control, there won’t be real growth in the MRR of your active customer base—no matter how fast it grows and how many new sales you make. The ultimate revenue you’re seeking will never be achieved!


What is net revenue retention (NRR)?


Net Revenue Retention is a percentage metric that illustrates the amount of revenue from your active customers that you are able to retain and expand over a specific period. This equation considers values like upgrades, downgrades, and churn.


It’s not as well-known as MRR or ARR, but it’s quite important—especially for SaaS companies. That’s because it’s exceedingly common for these businesses to increase their MRR but still lose money.


Yes, you read that right; it’s possible, and quite likely, for a software company to reach a point in its growth where it expands its MRR but ultimately loses money.


This scenario occurs when marketing and sales teams are operating at full capacity, and customer acquisition is outpacing the ability to retain and expand accounts.


Let’s take a practical example. Your SaaS started this month with $100,000 in MRR. Of that amount, $50,000 came from NMRR (New Monthly Recurring Revenue) from newly acquired customers. However, you also lost $20,000 in downgrades, earned no upgrades, and lost an additional $5,000 in churn.


In this example, your MRR increased by 50%. While that’s a figure worth celebrating, your NRR is only 75%—leading to a 25% decrease in MRR from your active customer base. That’s a pretty significant hole in your bucket! Once you analyze your CAC (Customer Acquisition Cost), does it add up?


The perfect formula: Increase your MRR and reduce churn


The formula for achieving a good NRR involves working on two pillars: Boosting MRR and “holding onto” the decrease in MRR, primarily by avoiding churn. Let’s break it down:


Boosting MRR


The two main mechanics for boosting MRR are through acquiring new customers or upgrading existing ones.


The process of upgrading your existing customers is called “upselling,” and can generally occur in two ways:


  1. Offering new features or tools only available in a more expensive subscription tier.
  2. Expanding any usage limits applied to your existing software, such as increased database sizes, more accounts, or increased bandwidth.


Losing MRR


Your business relies heavily on keeping active, paying customers subscribed to your service for as long as possible. With that in mind, loss of MRR from customers can occur in two ways:


  1. Through downgrades, which would represent a partial loss of revenue from a customer.
  2. Through churn, which would represent a complete loss of revenue from a customer.


Account cancellations are the worst case scenario for subscription-oriented businesses. Not only do you lose out on future payments from that customer, but any additional revenue from potential upsell opportunities has vanished.


How can I calculate my company’s NRR?


The formula for calculating NRR takes into account the following elements over a specific period:


  • Initial Monthly Recurring Revenue (MRR Initial)
  • Upgrades (Expansion MRR)
  • Downgrades (MRR Contraction)
  • Churn



NRR = (MRR Initial + Expansion MRR - Contraction MRR - Churn) / MRR Initial

If you plug in the values from our example at the beginning of this article, your NRR would be 75%. Any value under 100% indicates a potential loss in revenue. Therefore, in this example, if you were to stop selling new accounts your company would lose 25% of its monthly revenue.


What is a good NRR?


To start, understand that an NRR below 100% should be investigated as soon as possible. What if your NRR is higher, though? What would a good value be?


A review of 40 publicly traded SaaS companies found a median 109% NRR. Consider this a good reference point.


Box led the pack with over 120% NRR—a great result for a SaaS company!


How can I improve my NRR from now on?


Product strategy


If your product truly adds value and facilitates their entire journey as they mature in their use of your product, then you’ll automatically achieve the lock-in you’re seeking. Customer adoption of your product is a crucial element in decreasing churn and, additionally, paving the way for upgrades down-the-road.


Go-to-market strategy


If your strategy for acquiring new customers is not aligned with your Ideal Customer Profile (ICP) then you risk onboarding new accounts that just won’t stick. This can undermine an otherwise successful retention strategy and seriously harm your NRR. Instead, ensure that you’re reaching customers who are the right fit.


Retention strategy


Suppose you have a great product and a well-thought-out Go-To-Market strategy, but you’re still experiencing churn. In this scenario, you’ll want to take a look at your Customer Success operation. Consider your customer’s journey from the moment of onboarding to the day-to-day interactions. You want your clients to thrive when using your software. This is a good moment to consider upsell paths as well.


There are many ways to improve upon these three strategies. You could improve your added value offerings, increase the stickiness of your product, or refine your customer support offering.


Many of our own customers have found great success in offering websites to customers. Appfolio, for example, saw a 4.8% decrease in churn and a whopping 34% increase in value added services.


So, how's your NRR?

One of the greatest challenges for SaaS platforms is keeping users engaged long-term. The term “stickiness” refers to a product's ability to retain users and make them want to return. In the context of SaaS platforms, creating a sticky product means that users consistently find value, experience seamless interactions, and continue using the product over time. The following are 7 practical strategies you can take to improve the stickiness of your SaaS solution. 1. Offer websites that help customers build their digital presence One of the most effective ways to make your SaaS platform sticky is by offering websites to your users. Many businesses today need an online presence, and by providing a platform where your customers can easily build and manage their websites, you increase their reliance on your product. When you offer users a website-building solution, you’re helping them create something foundational to their business. Websites, in this case, aren’t just a tool—they become a part of their identity and brand. This deepens their engagement with your platform, as they need your product to maintain and update their site, ultimately making them less likely to churn. Plus, websites naturally encourage frequent updates, content creation, and customer interactions, which means your users will return to your platform regularly. When you can give your users the tools to create something so essential to their business, you make them more dependent on your platform. This creates a higher barrier to exit, as migrating a fully built website to another service is no small task. In fact, websites are some of the stickiest products you can sell, so adding them to your product portfolio can be one of the best decisions you can to keep your customers using your technology for the long haul. 2. Deliver continuous value through product innovation The key to keeping users coming back to your SaaS platform is ensuring that they consistently see value in it. This means not only meeting their immediate needs but also evolving to address their growing demands. Constant product innovation is essential for keeping your users satisfied and invested in your platform. One way to achieve this is through regular updates that add new features or improvements based on user feedback. A SaaS platform that evolves with its users will keep them engaged longer, making it harder for competitors to steal their attention. Encourage user feedback and prioritize updates that create tangible improvements. This creates an ongoing relationship with your users, which boosts stickiness. 3. Offer a multi-product solution Another powerful way to increase your platform’s stickiness is by offering a suite of products or features that integrate well together. When your users adopt multiple products, they are more likely to stay because they become embedded in your ecosystem. The benefits of this strategy are clear. Research shows that once users adopt more than one product, especially when they integrate >4 tools into their workflow, their likelihood of churn decreases significantly. This happens because the more a user integrates into your suite of products, the harder it is for them to switch to a competitor. These users have invested time in learning your ecosystem and rely on it for their day-to-day operations, making it much harder for them to make the switch. 4. Create a personal connection with your users Human connection is one of the most powerful drivers of user retention. People don’t want to feel like they’re using a cold, faceless platform. By offering exceptional customer support, personalized communication, and community engagement, you build a relationship with your users that goes beyond the product itself. Make sure your support team is responsive, knowledgeable, and empathetic. You can also consider offering tailored onboarding experiences to ensure users understand how to make the most of your platform. When users feel like their success matters to you, they are more likely to remain loyal. 5. Leverage data to personalize the user experience Using data to drive personalization is another strategy that can significantly increase the stickiness of your platform. By tracking user behavior and usage patterns, you can tailor the experience to each individual user’s needs. This could mean recommending features they haven’t yet explored or sending them reminders about tools they may not be fully utilizing. Personalization gives users the feeling that the platform was designed specifically for them, making it harder to walk away from. By demonstrating that you understand their unique needs, you can build a stronger connection and ultimately increase retention rates. 6. Focus on seamless integrations and API capabilities To further increase stickiness, consider expanding your product’s ability to integrate with other tools your users already rely on. Whether it’s email marketing software, CRM systems, or social media management tools, seamless integrations add tremendous value by making it easier for users to incorporate your platform into their existing workflows. The more your product can work in tandem with other popular tools, the more indispensable it becomes. In fact, users who depend on integrations are less likely to churn since their entire ecosystem is tied to your platform’s functionality. 7. Encourage user advocacy and community building User advocacy is another powerful tool in building a sticky product. When users feel a sense of community or even ownership over the platform, they become your most passionate promoters. Encourage your users to share their success stories, join community forums, or contribute to product development through beta testing or feedback loops. A thriving user community not only increases user engagement but also creates a sense of loyalty. When users are part of something larger than themselves, they are more likely to remain committed to your platform, reducing churn and increasing lifetime value. Create deep, lasting customer relationships Making your SaaS platform sticky is all about creating a deep, lasting connection with your users. This requires building a platform that continuously delivers value, creating a seamless and personalized experience, and integrating features that keep users coming back. By focusing on product innovation, offering a multi-product ecosystem, and fostering strong user relationships, you’ll be well on your way to reducing churn and boosting user retention. Stickiness isn’t just a nice-to-have; it’s essential for long-term success. Focus on creating a platform that users can’t imagine living without, and you’ll see them stick around for the long haul.
