Nowadays, it is no longer enough just to attract customers, since the biggest challenge is to understand their behavior and maximize the value they generate over time. That is why we use metrics such as retention rate, Customer Lifetime Value (CLTV) and Net Revenue Retention (NRR) if we want our business to grow sustainably.
Let’s think about this: do you really know the impact of each customer on your business? How well are you retaining your current customers, and how much value do they bring in the long term? These questions are more than rhetorical; they are the foundation of a strategy aimed at resource optimization, continuous improvement and loyalty.
This article will guide you through what these metrics mean, how to calculate them correctly, and how they can become strategic tools to refine your business.
Why measurement matters
The old business adage says that “what can’t be measured, can’t be perfected” is that without clear metrics, our decisions are based on assumptions, which increases the risk of investing resources in the wrong initiatives. Meanwhile, measuring allows companies to:
- Identify areas for improvement: metrics reveal whether customers are satisfied and whether the business is meeting their expectations.
- Evaluate existing strategies: measuring helps determine whether retention, upselling and cross-selling strategies are generating the expected impact.
- Projecting growth: with established metrics, companies can predict future revenue and plan investments more accurately.
The heart of the business: satisfied and engaged customers.
All these metrics converge on a central point: the customer. Measuring and optimizing retention rate, CLTV and NRR strengthens the financial health of the business and allows building long-lasting relationships. It is necessary to understand that business success is not based solely on initial sales, but on the ongoing value that is created over time.
How to achieve it:
- Invest in the customer experience: from efficient onboarding to proactive support, every interaction must add value.
- Personalize strategies: use data to design loyalty programs and targeted offers that resonate with individual customer needs.
- Continuously monitor: review these metrics regularly to identify patterns and adjust strategies in real time.
Defining retention rate, CLTV and NRR.
Before diving into the calculations and analysis, it is important to understand what retention rate, CLTV and NRR represent and why they are critical to measuring the success of your business.
Retention rate
It measures the percentage of customers who remain active during a specific period. It is an essential metric to evaluate the effectiveness of your loyalty strategies and the value that customers perceive in your product or service. As we already know, acquiring new customers is increasingly costly, so retaining existing ones is not only cheaper, but also more strategic.
Basic formula:
The impact of retention:
- Churn reduction: a high retention rate means satisfied and engaged customers, minimizing the loss of recurring revenue.
- Financial stability: retaining customers ensures a solid base of predictable revenue, allowing you to plan with confidence.
- Brand loyalty: loyal customers generate revenue, act as brand advocates and attract new users through word of mouth.
2. Customer Lifetime Value
Calculates the total value that a customer brings throughout their relationship with your company. This metric estimates revenue generated and considers acquisition and service costs, so it is an effective indicator of profitability and a guide to where to focus resources to maximize ROI.
Basic formula:
Why CLTV is important:
- Effective segmentation: helps identify high-value customers to prioritize specific loyalty and expansion strategies.
- Cost optimization: by measuring CLTV in relation to customer acquisition cost (CAC), companies can assess the profitability of their marketing and sales campaigns.
- Informed decision-making: CLTV guides investments in key areas, such as technical support or personalization, ensuring that each customer reaches their full potential.
Net Revenue Retention
Measures how much of the recurring revenue generated by existing customers is retained after accounting for expansions, contractions, and churn.
Basic formula:
Benefits of NRR:
- Business health indicator: an NRR above 100% demonstrates that the company is generating positive net revenue from its existing customer base, even after churn losses.
- Profitable growth: maximizing NRR through upselling and cross-selling strategies is more efficient than focusing solely on acquiring new customers.
- Attracting investors: businesses with a strong NRR are more attractive to investors, as they demonstrate financial stability and expandability.
How to calculate the retention rate, CLTV and NRR
Now that we understand what retention rate, CLTV and NRR are, let’s delve into how to calculate each of these metrics accurately.
1. Retention Rate Calculation
To calculate this metric, follow these steps:
Step 1: Determine the analysis periods.
Define an appropriate time interval, such as monthly, quarterly or annually, depending on the business model.
Step 2: Collect key data
You need to know how many customers you had at the beginning, how many you acquired and how many were left at the end of the period.
Example: if at the beginning of the quarter you have 100 customers, acquire 20 new ones and lose 10, the formula would be:
2. Calculation of CLTV
To calculate the CLTV, follow this structure:
Step 1: Calculate the average revenue per customer.
Divide the total revenue generated by customers by the number of active customers.
Step 2: Determine the average length of the relationship.
Identify how many months or years, on average, customers stay with your company.
Step 3: Apply the formula
Multiply the average revenue by the average duration of the relationship and subtract the associated costs.
Example: if a customer generates €500 per year, stays with you for 3 years and the acquisition costs are €200, the CLTV is:
3. NRR calculation
To calculate the NRR, these are the steps:
Step 1: Identify the initial recurring revenue.
Record monthly or annual customer revenue at the beginning of the period.
Step 2: Add expansions and subtract contractions and churn.
Consider additional upselling revenues and subtract customer losses or reductions in your plans.
Step 3: Apply the formula
Divide the result by the initial revenue and multiply by 100.
Example: if you start with €10,000 in recurring revenue, you earn $2,000 for expansions, lose €1,000 for contractions and €500 for churn:
Common errors when calculating retention rate, CLTV and NRR.
When calculating the metrics retention rate, CLTV and NRR mistakes can be made that lead us towards erroneous conclusions and, consequently, to the implementation of ineffective strategies. For this reason, we analyze in depth the most common errors when measuring these metrics, their consequences and how to avoid them.
1. Incomplete or poorly structured data
Why it happens: One of the most frequent errors is using incomplete or outdated data. This can happen due to disorganized systems, misconfigured analysis tools or inconsistent data collection across teams.
Impact:
- Distortion of results: Missing data such as contractions or expansions in NRR can give the impression that the business is retaining more revenue than it actually generates.
- Wrong decisions:Basing strategies on inaccurate data can lead to inefficient allocation of resources and implementation of inappropriate tactics.
How to avoid:
- Automate data collection: implement analytics tools integrated with your CRM that automatically collect relevant data such as revenue, interactions, and customer behavior.
- Set clear standards:make sure all teams use consistent metrics and definitions.
- Regular audits: periodically review your data systems to identify and correct errors or gaps.
2. Ignoring customer segmentation.
Why it happens: Many companies calculate metrics such as CLTV and retention rate as an overall average for all customers, without segmenting them by key characteristics such as size, industry, or behavior.
Impact:
- Misleading averages: lumping all customers together can mask differences between segments, making it difficult to identify which are the most valuable or which are at higher risk of churn.
- Missed opportunities: Without segmentation, it is more difficult to customize retention or upselling strategies for different customer groups.
How to avoid:
- Segment before you calculate: divide your customers into meaningful groups (e.g., high-value versus occasional customers) and calculate metrics for each segment.
- Use advanced tools: platforms such as Gainsight or Totango offer segmentation capabilities that facilitate analysis.
- Take a granular approach: Instead of focusing only on averages, consider individual metrics within each segment to get a more complete picture.
3. Exclusion of relevant costs in the CLTV calculation.
Why it happens: Many companies make the mistake of calculating CLTV only considering the revenue generated by the customer, without subtracting associated costs, such as acquisition, technical support and maintenance costs.
Impact:
- Overestimation of profitability: ignoring costs can give the impression that customers are more valuable than they really are, which can lead to inappropriate investments in acquisition or retention.
- Unsustainable strategies: Without a clear view of the true cost of retaining customers, companies may implement loyalty or support programs that are not financially viable.
How to avoid:
- Include all relevant costs: when calculating CLTV, be sure to include acquisition costs (CAC), customer service, retention campaigns and any other recurring expenses.
- Use complementary metrics: combine CLTV analysis with CAC to calculate the CLTV/CAC ratio, a metric for evaluating customer profitability.
- Integrate measurement into CRM: use tools to automatically track both revenue and costs associated with each customer.
4. Lack of differentiation between net and gross retention.
Why it happens: the NRR calculation often fails to differentiate between gross and net revenue, which can lead to misunderstandings about actual business growth. For example, including expansions without considering contractions or churn can give an incomplete picture.
Impact:
- Misperception of growth:if only expansions are considered, NRR may appear high, even though the business is losing customers.
- Lack of focus on critical issues: ignoring contractions and churn can hide areas that need urgent attention.
How to avoid:
- Break down NRR: break down retained revenue into renewals, expansions, and contractions to understand what factors are driving (or slowing) growth.
- Analyzes both net and gross retention: gross retention measures retained revenue without including expansions, which provides a more realistic view of retention capacity.
- Sets specific objectives: defines distinct goals for improving each component of NRR, from renewal to expansion.
5. Errors in measuring the average length of relationship (CLTV).
Why it occurs: the average customer relationship duration is a factor in calculating CLTV, but is often underestimated due to inaccurate calculations or unrealistic assumptions.
Impact:
- Overestimation of CLTV:assuming that all customers have a long relationship can artificially inflate the calculated value.
- Failure to prepare for churn: ignoring the actual length of the relationship can lead to unpleasant surprises when customers leave earlier than expected.
How to avoid it:
- Analyze historical patterns: use historical data to calculate average duration based on actual behavior, not projections.
- Updates regularly: reviews and adjusts estimates as customer behavior or business model changes.
- Segment by duration: calculate average duration by customer segment for a more accurate view.

Conclusions
Measuring retention rate, CLTV and NRR offer a clear window into what’s working and what needs tweaking in your strategy, helping you make more effective decisions.
For starters, the retention rate shows you how well you’re taking care of your current customers. If you find that this number is low, don’t be alarmed; instead, use it as an opportunity to investigate why and improve. Remember that retaining an existing customer is more profitable than acquiring a new one.
On the other hand, CLTV helps you calculate how much value each customer generates throughout their relationship with you. Here it is important to work on strategies such as upselling, cross-selling or loyalty programs to maximize this value. Don’t forget to balance it with acquisition and service costs to maintain a profitable relationship.
The NRR, meanwhile, is the best ally to evaluate whether your business is growing organically with existing customers. A score above 100% indicates that you are on the right track, but if you see contractions or high churn, act fast to identify and fix the problems.
One final tip: make these metrics a regular part of your analysis. Involve all teams, from marketing to support, to work together to improve the customer experience. Use technology tools to automate calculations and get faster insights, but don’t underestimate the power of the human touch to connect with your customers.
