Cos'è Customer Acquisition Cost?
Definizione Rapida
Il Customer Acquisition Cost (CAC) è il costo totale per acquisire un nuovo cliente, incluse le spese di marketing e vendita divise per il numero di nuovi clienti acquisiti.
CAC answers a simple question: how much do you spend to get one new customer? The formula is: Total Marketing + Sales Costs ÷ Number of New Customers = CAC. If you spend $10,000 on marketing in a month and acquire 100 customers, your CAC is $100.
A comprehensive CAC calculation includes all costs involved in acquisition: advertising spend, content creation costs, marketing tools and software, marketing team salaries, sales team salaries and commissions, CRM and sales tools, and any other costs directly tied to customer acquisition.
CAC varies dramatically by industry, business model, and channel. SaaS companies might have $200-$1,000 CAC, while e-commerce might be $10-$50. B2B enterprise sales can have CAC in the tens of thousands due to long sales cycles and relationship-based selling.
CAC should always be analyzed alongside Customer Lifetime Value (LTV). The LTV:CAC ratio indicates whether your business model is sustainable. A ratio of 3:1 or higher is generally considered healthy — meaning a customer generates at least 3x the cost to acquire them. Below 1:1 means you're losing money on every customer.
Perché è Importante
If you don't know your CAC, you can't know if your marketing is profitable. You might think your Facebook ads are working because they're generating signups, but if each signup costs $500 and your average customer is only worth $200, you're losing money on every sale.
CAC is also essential for financial planning and fundraising. Investors want to see that you have an efficient, scalable acquisition engine — not that you're buying growth at unsustainable costs.
Esempi Pratici
A SaaS startup's CAC was $800 through paid search but only $150 through content marketing — they shifted budget from ads to content, reducing blended CAC from $600 to $250
An e-commerce brand's Facebook Ads CAC increased from $25 to $65 after iOS privacy changes — they diversified into influencer marketing and email referrals to bring blended CAC back to $35
A B2B company calculated that their $15,000 CAC was justified by a $180,000 average contract value (12:1 LTV:CAC ratio), but reduced it to $10,000 through a self-serve trial option
A subscription service discovered that customers acquired through referrals had a $12 CAC vs $45 for paid ads, and also had 50% lower churn — they invested heavily in their referral program
