    What is CAC (Customer Acquisition Cost)?

    CAC is calculated by dividing total marketing and sales cost in a given period by the number of customers acquired in that period. Ad budget, team salaries, tool licences, agency fees and campaign production costs — every direct and indirect line item — belongs in this calculation.

    CAC on its own isn't good or bad; it only becomes meaningful next to LTV (Lifetime Value) and CAC payback period. The widely accepted rule is that LTV / CAC of 3x or higher signals healthy unit economics; a ratio below 1 means every new customer loses money for the business.

    The best strategies for optimising CAC are channel-level attribution, conversion rate optimisation, shortening the sales cycle and strengthening organic and referral channels. Alignment between marketing and sales is one of the most decisive operational factors.

    //Frequently Asked Questions

    What should be included in CAC?

    Ad spend, marketing and sales team salaries and bonuses, tool/software licences, agency and third-party fees and campaign production costs all belong in CAC.

    What's a good CAC value?

    There is no absolute good CAC — it's judged against LTV. Aim for LTV / CAC ≥ 3x and CAC payback under 12 months for B2B SaaS.

    How do you lower CAC?

    Conversion rate optimisation (CRO), re-balancing channel mix by efficiency, strengthening organic/SEO and referral programmes, and shortening the sales cycle are the highest-impact levers.

    Blended CAC vs. Paid CAC — what's the difference?

    Blended CAC includes all customers (organic + paid). Paid CAC counts only those acquired through paid channels — better for judging channel efficiency.
