#47# Formula and Calculation
The Customer Acquisition Cost (CAC) is calculated by dividing the total costs associated with acquiring new customers by the number of new customers gained within a specific period.
$46$
\text{CAC} = \frac{\text{Gesamte Marketing- und Vertriebskosten}}{\text{Anzahl der gewonnenen Neukunden}}
\text{CAC} = \frac{\text{€100,000}}{\text{200 Neukunden}} = \text{€500 pro Neukunde}
This means TechFlow Solutions spent an average of €500 to acquire each new customer in that quarter. To properly assess this, TechFlow would compare this CAC to the average [Kundenlebenszykluswert (CLV)](https://diversification.com/term/kundenlebenszykluswert-clv) of its customers and evaluate its [Rentabilität](https://diversification.com/term/rentabilitaet). ## Practical Applications Kundenakquisekosten is a fundamental metric used across various business functions and industries to inform strategic decisions. In [Marketingstrategie](https://diversification.com/term/marketingstrategie), it guides budget allocation across different channels, allowing businesses to identify the most cost-effective ways to attract new customers. For example, if a company f[^30^](https://vibetrace.com/de/kundengewinnungskosten/), [^31^](https://www.altdigital.tech/resources/altdigitalpedia/customer-acquisition-cost-cac)inds its CAC is lower through content marketing than through paid advertising, it might shift more [Marketingausgaben](https://diversification.com/term/marketingausgaben) to content. In financial planning, CAC, alongside [Kundenlebenszykluswert (CLV)](https://diversification.com/term/kundenlebenszykluswert-clv), helps assess the long-term viability and [Skalierbarkeit](https://diversification.com/term/skalierbarkeit) of a business.

One significant challenge is the accurate attribution of costs, especially when customers interact with multiple touchpoints or channels before converting. Determining which specific [^23^](https://fastercapital.com/topics/challenges-and-limitations-of-customer-acquisition-cost-analysis.html/1), [^24^](https://fastercapital.com/topics/common-challenges-and-pitfalls-in-customer-acquisition-cost-calculation.html)marketing or sales effort led to a conversion can be complex, potentially distorting the true CAC for individual channels. For instance, a customer mi[^22^](https://fastercapital.com/topics/challenges-and-limitations-of-customer-acquisition-cost-analysis.html/1)ght see an online ad, then receive an email, and finally convert after a sales call. Appropriately allocating costs across these different interactions is difficult. Moreover, CAC typically focuses only on the initial acquisition, without accounting for customer quality or future [Kundenbindung](https://diversification.com/term/kundenbindung). A low CAC might be achieved[^20^](https://fastercapital.com/topics/challenges-and-limitations-of-customer-acquisition-cost-analysis.html/1), [^21^](https://www.copy.ai/blog/customer-acquisition-costs) by attracting low-value customers who churn quickly, leading to a negative [Deckungsbeitrag](https://diversification.com/term/deckungsbeitrag) in the long run. External factors such as ma[^19^](https://sumosum.com/customer-acquisition-cost/)rket conditions, intense competition, or evolving customer preferences can also significantly influence CAC, making historical data less predictive for future planning. The focus on CAC alone can [^17^](https://fastercapital.com/topics/challenges-and-limitations-of-customer-acquisition-cost-analysis.html/1), [^18^](https://97thfloor.com/articles/glossary/customer-acquisition-cost-cac/)sometimes lead companies to underinvest in brand building or long-term strategies that do not yield immediate customer acquisition, but contribute significantly to overall [Kundenwert](https://diversification.com/term/kundenwert) [https://www.mckinsey.com/capabilities/growth-marketing-and-sales/our-insights/the-future-of-marketing-returns-measurement].
