Customer Acquisition Cost (CAC) Calculator
CAC shows you how much it costs to win a new customer. This matters because growth gets expensive fast when your acquisition cost is not tied to the revenue each customer produces.

What is this?
A calculator that shows what you are paying to acquire each customer overall and by channel.
How does it work?
Enter spend and customer counts, then compare the resulting CAC across your total period and up to three channels.
Who should use it?
Use it if you run paid campaigns, track referrals, or want clearer channel economics before scaling spend.
Calculate Customer Acquisition Cost
Use the overall CAC to judge whether your acquisition model is healthy before you increase budget. Then compare channel CAC below to see where the waste sits.

What is a Good CAC?
There is no single good CAC across every industry. Medspa and clinic offers can often support a higher CAC if patient value compounds over repeat visits. Real estate usually tolerates a wider CAC range because commissions are larger but conversion windows are longer. SaaS teams usually judge CAC against payback period and retention. Immigration firms often accept a higher CAC when consultation quality is strong and close rates hold up.
In high-competition markets like UAE and Dubai, where paid traffic costs more, CAC benchmarks tend to run higher than equivalent campaigns in Canada or UK. The ratio that matters most is CAC relative to lifetime value, regardless of which market you operate in.
How to Reduce CAC
- Improve speed to lead so more of your existing leads convert before they go cold.
- Break out channel performance so weak campaigns do not hide inside blended averages.
- Raise booking and close rates before increasing spend, especially if leads are already coming in.
- Use retargeting, reactivation, and follow-up automation to get more revenue from the same acquisition cost.
CAC Questions
What is customer acquisition cost?
Customer acquisition cost is the average amount you spend to acquire one new customer over a defined period.
How do you calculate CAC?
You divide total marketing and sales spend by the number of new customers acquired during the same period.
What is a good CAC for a medspa or clinic?
A good CAC depends on treatment value and retention. Higher-ticket clinics can usually support a higher CAC than low-ticket offers as long as the revenue per client justifies it.
What is the difference between CAC and CPL?
CPL measures the cost to generate a lead. CAC measures the cost to turn that effort into an actual customer.
How does CAC relate to LTV?
CAC only makes sense when compared to lifetime value. If your CAC is too close to or higher than LTV, your growth model is under pressure.
