Customer Lifetime Value (CLV): Calculating Customer Value

Why CLV is so important (and often underestimated)

Many companies focus on short-term KPIs such as leads, deals or conversion rates. CLV goes one step further and answers crucial questions:

• How much should a customer cost me to acquire?
• Which customers are particularly profitable?
• Where is retention more worthwhile than acquiring new customers?

CLV is not merely a marketing KPI – but a company-wide control lever. Companies that take CLV seriously shift their focus from ‘more customers’ to ‘better customers’.

This formula brings CLV much closer to reality, as it:

• takes into account profitability (margin)
• incorporates actual purchasing behaviour (repeat purchases)
• deducts the customer acquisition cost (CAC)

Here, it is no longer just revenue that is considered, but the true economic value of a customer.

Advanced CLV calculation (strategic level)

For truly robust management, the CLV should be supplemented by further factors:

• Discounting (time value of money): Future revenues are valued lower in the CLV than current revenues, as money can be used, invested or reinvested immediately today, and uncertainties (e.g. churn, inflation) increase over time.
• Churn rate (probability of churn): This describes the probability of a customer leaving and how long they actually remain active – and thus has a direct influence on the realistic duration and amount of the Customer Lifetime Value.
• Up-selling and cross-selling potential: These demonstrate how customer value can be further increased over time through additional purchases, higher-value products or complementary services, thereby raising the Customer Lifetime Value.
• Service and support costs: These include ongoing expenses such as support, sales and account management, which must be deducted from the revenue generated in order to realistically determine the actual economic customer value.

A ‘good’ CLV is not static – it changes continuously in line with the customer’s behaviour. Therefore, ideally, the CLV should be calculated and updated dynamically for each customer within the CRM.

What does this mean in practice?

A dynamic, data-driven CLV is crucial for the strategic management of marketing, sales and growth. The greatest leverage lies in embedding CLV within the CRM and actively utilising it – e.g. for budget allocation based on customer value, prioritisation in sales, and targeted retention and upselling measures.

This is exactly where kkvision comes in: from developing a suitable CLV model to integration into systems such as Microsoft Dynamics, HubSpot or Salesforce.

Optimising Customer Lifetime Value: The Key Leverage Points

Customer Lifetime Value can be specifically increased – the key is to utilise the right leverage points throughout the entire customer relationship. This is not just about generating more revenue, but about sustainable profitable growth.

Key levers for increasing CLV

• Systematically strengthening customer loyalty: The aim is to actively extend the duration of the relationship – through consistent customer experiences, relevant communication and genuine added value throughout the entire customer journey. The decisive factors here are not only service quality, but also targeted, data-driven engagement.
• Targetedly increasing the repurchase rate: Customers should not just buy once, but return regularly. This is achieved through automated CRM workflows, personalised offers and clearly structured follow-ups.
• Increasing revenue per customer (up-selling & cross-selling): Existing customers offer the greatest potential for additional revenue. Customer value can be gradually increased through suitable add-ons, higher-value products or complementary services.
• Identify and reduce churn at an early stage: Churn rarely occurs suddenly. With the right data, risks can be identified early (e.g. declining activity) and targeted countermeasures taken – before customers are lost.

CLV + Customer Acquisition Cost (CAC)

One of the most important metrics in marketing and sales is the ratio of Customer Lifetime Value to Customer Acquisition Cost (CLV/CAC). It shows whether the investment in customer acquisition pays off in the long term.

The following applies:

• CLV (Customer Lifetime Value) = long-term value of a customer
• CAC (Customer Acquisition Cost) = cost of acquiring a new customer

CLV/CAC – example of the calculation

A company generates an average value of €3,000 from a customer over the entire customer relationship. The marketing and sales costs to acquire this customer amount to €1,000.

This gives: 3,000 / 1,000 = 3

The CLV/CAC ratio is therefore 3:1.

This means: For every euro invested in customer acquisition, three euros of customer value are generated in the long term.

Rule of thumb for classification

• below 1: critical to unprofitable
  Acquisition costs are higher than the long-term customer value
• 1 to 3: fundamentally viable, but with room for improvement
  Customer acquisition pays off, but is not yet particularly efficient
• 3 and above: very good ratio
  The company acquires customers profitably and with sound financial performance

Why this metric is so important

The CLV/CAC ratio combines two key perspectives:

• How expensive is it to acquire customers?
• How valuable are these customers in the long term?

This is precisely why the metric is significantly more meaningful than isolated individual figures such as cost-per-lead or conversion rate. A low CAC appears positive at first glance, but is of little use if the acquired customers subsequently generate hardly any revenue or churn quickly.

What does this mean in practice?

Companies should not only evaluate their acquisition efforts based on how cheaply new customers are acquired, but above all on how profitable these customers are in the long term.

A higher CAC can therefore make perfect sense if:

• the customers acquired demonstrate a high level of loyalty
• they make repeat purchases on a regular basis
• there is additional potential for upselling or cross-selling

The key, therefore, is not to reduce the CAC as much as possible in isolation, but to create a healthy balance between acquisition costs and long-term customer value.

Advanced CLV: Customer Referral Value (CRV)

In an advanced CLV analysis, not only is a customer’s direct monetary value taken into account, but also their Customer Referral Value (CRV) – that is, the additional value they generate through referrals and by bringing in new customers.

As a result, a customer with low personal turnover but a high referral rate can be more valuable overall than a traditional frequent buyer who makes no referrals.

How is CRV calculated?

CRV is derived from the value of new customers acquired through referrals:

CRV = number of customers acquired × average CLV of these customers

The following can also be taken into account:

• Probability of referral
• Conversion rate of referrals
• Quality or value of the acquired customers

In practice, this means that, in addition to revenue and margin, influence, referrals and network effects should also be factored into the assessment. A prerequisite for this is that such data is recorded and analysed in the CRM – only in this way can the actual, holistic customer value be made visible and usable.
