In the competitive landscape of Software as a Service (SaaS), understanding and tracking Key Performance Indicators (KPIs) is crucial for any business to thrive. One such KPI that has gained significant attention in recent years is the Net Dollar Retention (NDR). This metric provides a comprehensive view of the financial health of a SaaS business, taking into account not just new sales, but also upsells, downgrades, and churn.

Understanding NDR can be complex, as it involves a deep dive into various aspects of a SaaS business model. This glossary entry aims to unravel the intricacies of NDR, providing a detailed explanation of its calculation, significance, and strategies to improve it. By the end of this entry, you will have a thorough understanding of NDR and its role in evaluating and enhancing the performance of a SaaS business.

Understanding Net Dollar Retention (NDR)

Net Dollar Retention (NDR) is a metric that measures the growth of existing customers in a SaaS business, taking into account upsells, downgrades, and churn. It is a powerful indicator of the financial health of a SaaS company, as it reflects the company’s ability to grow its revenue without relying solely on new customer acquisition.

NDR is particularly relevant for SaaS businesses because of their subscription-based model. In this model, customer relationships are ongoing, and revenue is generated over the lifetime of the customer, rather than in a single transaction. This makes the growth and retention of existing customers as important, if not more so, than acquiring new ones.

Calculation of NDR

The calculation of NDR involves several steps. First, you need to determine the Starting Monthly Recurring Revenue (MRR) for a specific cohort of customers. This is the MRR at the beginning of the period you’re measuring. Next, you calculate the Ending MRR for the same cohort, which is the MRR at the end of the period.

However, the Ending MRR is not simply the Starting MRR plus new sales. It also includes expansions (upsells or upgrades), contractions (downgrades), and churn (lost customers). Once you have the Starting and Ending MRR, you can calculate the NDR by dividing the Ending MRR by the Starting MRR and multiplying by 100 to get a percentage.

Interpreting NDR

A NDR of over 100% is generally considered good, as it indicates that the company’s revenue from existing customers is growing, even without taking new customer acquisition into account. A NDR of less than 100% suggests that the company is losing revenue from existing customers, which could be a sign of problems with customer satisfaction or product-market fit.

However, it’s important to note that the ‘ideal’ NDR can vary depending on the company’s stage, market, and business model. For example, a high-growth startup might aim for a higher NDR, while a mature company in a saturated market might have a lower target.

Importance of NDR in SaaS Businesses

NDR is a critical KPI for SaaS businesses for several reasons. Firstly, it provides a more holistic view of a company’s financial health than traditional metrics like customer acquisition cost (CAC) or customer lifetime value (CLV). While these metrics focus on individual aspects of the business (acquisition and retention, respectively), NDR takes into account the entire customer lifecycle.

Secondly, NDR is a forward-looking metric. It not only reflects the current state of the business, but also provides insights into future growth potential. A high NDR indicates that the company is not only retaining its existing customers, but also successfully upselling and cross-selling to them, which bodes well for future revenue growth.

Indicator of Product-Market Fit

NDR can serve as a valuable indicator of product-market fit. A high NDR suggests that the product is meeting the needs of its customers, who are not only sticking around, but also spending more over time. On the other hand, a low NDR could indicate that the product is not resonating with its target market, leading to churn and downgrades.

Furthermore, NDR can help identify trends in product-market fit over time. For example, if NDR is declining, it could suggest that the product is becoming less relevant to its market, perhaps due to increased competition or changing customer needs. This can signal the need for strategic adjustments, such as product enhancements or shifts in market positioning.

Tool for Investor Evaluation

Investors often use NDR as a tool to evaluate the potential of a SaaS business. A high NDR can be a strong selling point, as it indicates a healthy, growing customer base and a product that is resonating with its market. This can make the company more attractive to investors, potentially leading to increased funding and valuation.

Conversely, a low NDR can raise red flags for investors, as it suggests potential issues with customer retention and growth. This can impact the company’s ability to secure funding, and may require it to focus on improving its NDR before seeking further investment.

Strategies to Improve NDR

Improving NDR involves a combination of reducing churn, increasing upsells and cross-sells, and managing downgrades. This requires a deep understanding of your customers, their needs and behaviors, and the value they derive from your product.

It’s also important to have a robust customer success strategy in place. This involves proactive engagement with customers, regular check-ins to ensure they’re deriving value from the product, and swift action to address any issues or concerns.

Reducing Churn

Reducing churn is a key strategy to improve NDR. This involves identifying the reasons why customers are leaving, and taking steps to address these issues. This could involve improving the product, enhancing customer support, or offering more competitive pricing.

It’s also important to identify at-risk customers before they churn. This can be done through churn prediction models, which use data on customer behavior and usage patterns to predict which customers are most likely to churn. Once these customers are identified, you can take proactive steps to retain them, such as reaching out to discuss their concerns, offering special deals, or providing additional support.

Increasing Upsells and Cross-Sells

Another strategy to improve NDR is to increase upsells and cross-sells. This involves identifying opportunities to sell more to your existing customers, either by upgrading them to a higher-tier plan (upselling), or by selling them additional products or features (cross-selling).

This requires a deep understanding of your customers and their needs. By analyzing customer usage data and feedback, you can identify which customers are most likely to benefit from an upsell or cross-sell, and tailor your sales approach accordingly. It’s also important to provide clear value propositions for your upsells and cross-sells, to convince customers of the benefits of upgrading or adding on to their current plan.

Managing Downgrades

Finally, managing downgrades is an important part of improving NDR. This involves understanding why customers are downgrading, and taking steps to prevent or mitigate these downgrades.

This could involve improving the value proposition of your higher-tier plans, to make them more attractive to customers. Alternatively, it could involve offering more flexible pricing options, to accommodate customers with varying needs and budgets. In some cases, it might also involve improving the product or customer support, to address the issues that are leading customers to downgrade.


Net Dollar Retention (NDR) is a powerful KPI for SaaS businesses, providing a comprehensive view of the financial health of the business and its future growth potential. By understanding and tracking NDR, SaaS businesses can gain valuable insights into their performance, identify areas for improvement, and make strategic decisions to drive growth.

However, improving NDR is not a one-size-fits-all process. It requires a deep understanding of your customers, their needs and behaviors, and the value they derive from your product. By focusing on reducing churn, increasing upsells and cross-sells, and managing downgrades, you can improve your NDR and drive sustainable growth for your SaaS business.
