Question 1

What is Customer Acquisition Cost (CAC)?

Accepted Answer

Customer Acquisition Cost is the total cost of acquiring a new customer, calculated by dividing your marketing and sales spend by the number of new customers gained. It tells you how much you're paying to bring each new person through the door.

Question 2

What is Customer Retention Cost (CRC)?

Accepted Answer

Customer Retention Cost is what you spend to keep existing customers coming back, divided by the number of customers retained. This includes loyalty programs, email marketing, special offers for regulars, and any other retention-focused spend.

Question 3

Why is retention cheaper than acquisition?

Accepted Answer

Existing customers already know and trust your business. You don't need to spend on awareness, first impressions, or overcoming skepticism. Research from Bain & Company shows acquiring a new customer costs 5–25x more than retaining one. Harvard Business Review found that a 5% increase in retention can boost profits by 25–95%.

Question 4

What is a good CAC to CRC ratio?

Accepted Answer

Most businesses see a ratio between 5:1 and 10:1 — meaning acquisition costs 5–10x more per customer than retention. If your ratio is lower, it may mean you're underinvesting in retention or your acquisition channels are very efficient.

Question 5

How can I reduce my Customer Acquisition Cost?

Accepted Answer

Three effective approaches: (1) Invest in retention so you need fewer new customers to grow, (2) Leverage word-of-mouth from loyal customers — the cheapest acquisition channel, (3) Optimize your marketing channels to focus spend on what actually converts.

Question 6

How does a loyalty program reduce CAC?

Accepted Answer

Loyalty programs reduce CAC indirectly by increasing customer retention and lifetime value. When customers stay longer and spend more, you need fewer new customers to hit revenue targets. Plus, loyal customers refer friends — creating free acquisition.

Question 7

What industries benefit most from focusing on retention?

Accepted Answer

Any business with repeat purchase potential benefits, but especially food and beverage, retail, beauty, fitness, and pharmacies. These industries have high visit frequency potential, making each retained customer significantly more valuable than a one-time visitor.
