Customer Acquisition Cost (CAC) shows how much it costs to gain a new customer. It’s a key metric for startups to track profitability and growth.
Quick Summary:
- Formula: CAC = Total Marketing & Sales Costs ÷ Number of New Customers
- Why It Matters: Helps allocate resources, plan growth, and ensure profitability.
- Key Components:
- Marketing/Sales Costs (ads, salaries, tools)
- Measurement Period (monthly, quarterly)
- Customer Count (exclude free trials, count only new customers).
Example:
If you spend $60,000 on marketing in Q1 2025 and gain 200 customers, your CAC = $60,000 ÷ 200 = $300 per customer.
Advanced Tips:
- LTV/CAC Ratio: Compare CAC to your customer’s lifetime value (aim for 3:1 or higher).
- Optimize Channels: Break down CAC by channel to find the most cost-effective ones.
- Reduce CAC: Use free channels (SEO, referrals), improve conversion rates, and leverage automation tools.
Accurately tracking and managing CAC ensures your startup grows efficiently and sustainably.
How To Calculate Customer Acquisition Cost (CAC) In 2023 …
CAC Components
Let’s break down the main components of Customer Acquisition Cost (CAC): Marketing and Sales Costs, Measurement Period, and Customer Count.
Marketing and Sales Costs
Here are some typical costs that go into calculating CAC:
| Cost Category | Examples | What’s Included |
|---|---|---|
| Advertising | PPC campaigns, social media ads | Ad spend, platform fees |
| Personnel | Sales reps, marketing team | Salaries, commissions, benefits |
| Tools & Software | CRM systems, marketing tools | Subscriptions, setup fees |
| Content Creation | Blog posts, videos, whitepapers | Production costs, freelancer fees |
| Events | Trade shows, webinars, conferences | Booth fees, travel, materials |
These costs cover everything from creating campaigns to the tools and people needed to execute them.
Measurement Period
Pick a measurement period that lines up with your sales cycle. Monthly or quarterly periods often work best because they:
- Match the length of your sales cycle
- Cover entire marketing campaigns
- Account for seasonal trends
- Stay consistent over time
For example, if your sales cycle lasts 45 days, a quarterly window will give you a more accurate picture than a monthly one.
Customer Count
When calculating CAC, it’s important to track new customers accurately. Use data from:
- CRM systems for paid accounts
- Payment processor records
- User registration timestamps
- Contract start dates
A few key points to keep in mind:
- Don’t include free trial users unless they convert
- Count each new customer only once
- Separate new customers from recurring ones
- Record acquisition dates carefully

CAC Calculation Steps
Basic CAC Formula
CAC = Total Marketing and Sales Costs / Number of New Customers Acquired
This formula gives startups a clear picture of how much they’re spending to bring in each new customer over a specific time period. To calculate it accurately, follow the steps below.
Calculation Method
Here’s how to calculate your CAC:
- Add up all marketing and sales expenses (e.g., advertising, employee salaries, software subscriptions, content production, event costs).
- Count only new customers acquired during the period – exclude free trials, renewals, and leads that didn’t convert.
- Divide the total costs by the number of new customers.
CAC Example
Let’s break it down with an example of a quarterly CAC calculation:
| Expense Category | Q1 2025 Cost |
|---|---|
| Digital Ads | $15,000 |
| Sales Team (2 reps) | $30,000 |
| Marketing Tools | $2,500 |
| Content Creation | $5,000 |
| Event Marketing | $7,500 |
| Total Costs | $60,000 |
Q1 2025 New Customers: 200
Calculation: $60,000 ÷ 200 = $300 per customer
This figure can help you evaluate:
- Whether your pricing covers customer acquisition costs.
- Which marketing efforts are delivering the best return on investment.
- If your growth strategy is financially sustainable.

Advanced CAC Metrics
Once you’ve calculated your basic CAC, you can dig deeper by analyzing advanced metrics. These go beyond the surface to provide a clearer picture of your customer acquisition strategy.
Total CAC
Total CAC takes into account extra costs beyond just marketing and sales, such as:
- Customer onboarding
- Initial customer support
- Product training materials
- Technical setup
- Account management during the first 90 days
For example, if your basic CAC is $300 per customer, your Total CAC might look like this:
| Cost Component | Amount per Customer |
|---|---|
| Basic CAC | $300 |
| Onboarding Support | $75 |
| Initial Training | $50 |
| Technical Setup | $25 |
| Early Account Management | $100 |
| Total CAC | $550 |
LTV/CAC Ratio
The LTV/CAC ratio shows how your customer acquisition spending stacks up against the lifetime value (LTV) of your customers. A ratio of 3:1 or higher is usually a good sign.
Formula: LTV ÷ CAC = LTV/CAC Ratio
Here’s an example: If your average customer stays for 2 years, pays $100 per month, and your Total CAC is $550:
- LTV = $100 × 24 months = $2,400
- LTV/CAC Ratio = $2,400 ÷ $550 = 4.36
This 4.36:1 ratio indicates a strong return on your acquisition investment.
CAC by Channel
Breaking down CAC by channel helps you see which methods deliver the best results. Here’s an example:
| Marketing Channel | Monthly Spend | New Customers | CAC |
|---|---|---|---|
| Google Ads | $10,000 | 40 | $250 |
| LinkedIn Ads | $8,000 | 20 | $400 |
| Content Marketing | $5,000 | 25 | $200 |
| Email Marketing | $3,000 | 15 | $200 |
| Trade Shows | $15,000 | 25 | $600 |
CAC Reduction Methods
Cutting customer acquisition costs (CAC) is key to boosting profitability. Based on your CAC analysis, here are some practical ways to lower costs while keeping customer relationships strong.
Free Marketing Channels
Leverage free marketing channels to drive down CAC. A clear communication strategy can help you effectively reach your audience through organic methods:
- SEO: Boost organic traffic by optimizing your website, crafting compelling meta descriptions, and building quality backlinks.
- Content Marketing: Develop content like blog posts, whitepapers, and case studies that solve your audience’s problems.
- Referral Programs: Encourage word-of-mouth growth by rewarding customers for referrals.
| Channel | Time Investment | Potential Impact |
|---|---|---|
| SEO | High | Long-term organic traffic |
| Content Marketing | Medium | Sustained lead generation |
| Referral Programs | Low | Word-of-mouth growth |
To maximize results, focus on improving how efficiently you convert organic traffic into leads or customers.
Better Conversion
Improving conversion rates can make every marketing dollar go further. Key areas to focus on include:
- Landing Pages: Refine your landing pages to highlight value clearly. Use A/B testing to perfect your messaging and design.
- Sales Funnel: Simplify your funnel to guide prospects smoothly through the buying process. Identify and fix points where users drop off.
- User Experience: Ensure your website is easy to navigate, loads quickly, and works well on mobile devices.
Streamlining these areas can significantly enhance your ability to convert leads into paying customers.

Automation tools can take repetitive tasks off your plate while keeping communication consistent and effective:
