The CAC Formula

Customer acquisition cost is calculated by dividing your total sales and marketing expenses by the number of new customers acquired in the same period. If you spent $20,000 on marketing last month and acquired 100 customers, your CAC is $200.

Include everything: ad spend, salaries for marketing and sales staff, tools and software, content creation costs, and agency fees. Leaving out costs gives you a misleadingly low number.

What Is a Good CAC

There is no universal benchmark because it varies wildly by industry. A good rule of thumb is that your customer lifetime value should be at least three times your CAC. If your CLV is $600, your CAC should be under $200 for healthy unit economics.

Reduce CAC Through Better Targeting

The fastest way to lower CAC is to stop spending on audiences that do not convert. Analyse your customer data to identify your most profitable segments and focus your marketing on reaching more people like them. Lookalike audiences on Meta and Google are powerful tools for this.

Improve Your Conversion Funnel

You might not need more traffic. You might just need to convert more of the traffic you already have. Test your landing pages, simplify your signup process, and ensure your value proposition is crystal clear above the fold. A 1% improvement in conversion rate can reduce your CAC significantly.

Invest in Organic Channels

Paid advertising delivers fast results but keeps your CAC high because you pay for every click. Content marketing, SEO, and social media build assets that generate leads over time with decreasing marginal cost. The upfront investment is higher but the long term CAC is dramatically lower.

Leverage Referrals and Word of Mouth

Referred customers typically cost 60 to 80% less to acquire than those from paid channels. Build a referral program, encourage reviews, and make it easy for happy customers to spread the word.

Use Commission Based Sales

Hiring commission only sales agents through platforms like Zepys effectively turns your CAC into a variable cost. You only pay when a sale is made, which means your acquisition cost is predictable and directly tied to revenue rather than being an upfront gamble on ad spend.
