How to Calculate Customer Acquisition Cost
What is CAC?
Customer Acquisition Cost (CAC) is a metric that measures how much your business spends to acquire a new customer. It’s calculated by dividing your total acquisition costs by the number of new customers acquired during a specific period.
How to Calculate
CAC = (Marketing Cost + Sales Cost) / Number of New Customers Acquired
Marketing costs include:
- Advertising costs (digital, print, TV, radio)
- Marketing team salaries
- Content creation expenses
- Marketing software costs
Sales costs include:
- Sales team salaries and commissions
- Sales software and tools
- Training and development
Optional Channel Analysis
For more detailed insights, you can optionally break down your acquisition costs by channel. This helps identify:
- Which channels deliver the lowest CAC
- Where to allocate more budget
- Which channels to optimize or discontinue
Churn Rate Impact
Churn rate (percentage of customers who leave) affects your effective CAC. If you have high churn, you need to acquire more customers just to maintain your customer base, which increases your effective acquisition cost.
Effective CAC = CAC / (1 – Churn Rate)

CAC Payback Period Calculation
CAC payback period measures how long it takes to recover your customer acquisition investment.

- Monthly Revenue per Customer: $100
- Monthly Cost to Serve: $20
- CAC Payback = $300 ÷ ($100 – $20) = 3.75 months

FAQs About CAC Calculator
To calculate CAC, divide your total acquisition costs by the number of new customers acquired during the same period. The formula is: CAC = Total Marketing & Sales Costs ÷ New Customers Acquired. Include all marketing expenses, sales team costs, and related overhead in your total acquisition costs.
CAC calculation includes all costs related to acquiring new customers: paid advertising spend, marketing team salaries, sales team compensation, marketing tools and software, creative development, agency fees, and allocated overhead costs. Don’t include customer success or product development costs, as these support retention rather than acquisition.
CAC payback period is calculated by dividing CAC by the monthly profit per customer. Formula: CAC Payback = CAC ÷ (Monthly Revenue per Customer – Monthly Cost to Serve). For example, if CAC is $200, monthly revenue is $50, and monthly costs are $10, the payback period is 5 months ($200 ÷ $40).
A good CAC for SaaS companies varies by stage and market. Early-stage SaaS typically sees CAC of $200-$400, while growth-stage companies range from $300-$500. Enterprise SaaS can have CAC of $500-$1,500+. The key is ensuring your CAC:LTV ratio is at least 1:3 and payback period is under 12 months.
CAC and CPA are often used interchangeably, but CAC specifically refers to acquiring new customers, while CPA can refer to any conversion action (sign-ups, downloads, leads). CAC focuses on actual paying customers and includes all associated acquisition costs, making it a more comprehensive business metric than CPA.
Blended CAC includes all acquisition channels (organic search, referrals, paid ads), while paid CAC only includes paid marketing channels. Blended CAC is typically lower because it includes “free” organic traffic, while paid CAC shows the true cost of scalable acquisition channels. Both metrics are important for different strategic decisions.
Calculate CAC monthly for tactical decisions and quarterly for strategic planning. Monthly calculations help optimize campaigns and budget allocation, while quarterly analysis reveals trends and seasonal patterns. Always use consistent time periods and ensure your attribution windows account for typical customer decision timelines.
Yes, calculating channel-specific CAC is crucial for optimization. Divide the total costs for each channel by the customers acquired through that channel. This helps identify your most cost-effective acquisition sources and guides budget allocation decisions. Track CAC for channels like Google Ads, Facebook, email marketing, and content marketing separately.
A CAC percentile calculator helps benchmark your customer acquisition costs against industry standards. It shows where your CAC falls within the distribution of similar companies, helping you understand if your acquisition costs are competitive, efficient, or need improvement compared to industry peers.
Reduce CAC by improving targeting precision, optimizing ad creative and landing pages, focusing budget on high-performing channels, implementing referral programs, and enhancing organic acquisition through SEO and content marketing. Also, improve conversion rates throughout your funnel and reduce sales cycle length to acquire customers more efficiently without sacrificing growth rate.
