What is the average customer acquisition cost (CAC)?
Customer acquisition cost (CAC) refers to the total investment a company makes to turn a prospect into a paying customer. It is one of the most important metrics in marketing analytics, offering clear visibility into how efficiently your sales and marketing operations are performing.
Whether you’re running a SaaS company, e-commerce store, or a professional services firm, your average customer acquisition cost tells you whether your customer growth is financially sustainable. If you’re spending more to acquire a customer than you can earn from them, it’s a signal that your strategy needs immediate adjustment.
For data-driven teams, CAC acts as a foundational KPI that informs channel performance, campaign ROI, and future growth strategy. Tools like Usermaven make it easy to track CAC over time and across acquisition channels, helping businesses make smarter decisions without relying on manual calculations or siloed reports.
How to calculate customer acquisition cost
The standard formula to calculate average customer acquisition cost is:
CAC = Total sales and marketing costs ÷ Number of new customers acquired
To use this formula accurately, define a specific time period, monthly, quarterly, or annually, and make sure both the cost and customer count reflect the same timeframe.
For example, if your business spent $40,000 on marketing and sales last quarter and gained 160 new customers, your average CAC would be:
$40,000 ÷ 160 = $250 per customer
While the formula seems simple, the true value lies in tracking changes over time, comparing performance across channels, and understanding how CAC affects overall profitability. This is where Usermaven’s real-time tracking and attribution features help you break down CAC by source and optimize acquisition investments accordingly.
What is considered a good customer acquisition cost?
A good customer acquisition cost (CAC) depends on your business model and industry. There’s no universal “ideal” number; what matters is how CAC compares to customer lifetime value (LTV). While CAC measures what you spend to acquire a new customer, LTV reflects the total revenue you expect from that customer over time.
The commonly accepted benchmark is to maintain an LTV: CAC ratio of at least 3:1 or 4:1. This means that for every dollar spent on acquisition, your business should earn $3–$4 in return. In other words, your CAC should be no more than one-third (or ideally one-fourth) of your LTV.
You can calculate this ratio with a simple formula:
LTV ÷ CAC = LTV:CAC ratio
If your ratio falls below 3:1, your acquisition strategy may not be sustainable. But if it’s too high (e.g., 6:1 or more), you might be under-investing in growth opportunities.
Costs to include in your CAC calculation
A comprehensive CAC calculation should include every cost tied directly to customer acquisition. This often includes:
- Paid advertising (search, social, display, etc.)
- Marketing team salaries and commissions
- Sales team costs (salaries, commissions, tools)
- Content production (copywriting, video, design)
- Marketing and CRM software subscriptions
- External agency or consultant fees
- Event sponsorships, promotions, or trade show costs
- Overhead related to acquisition efforts
Neglecting any of these elements leads to underreporting CAC, which can result in misguided budgeting decisions or overinvestment in underperforming strategies.
Many modern businesses also calculate channel-specific CAC to identify which platforms deliver the best return. For instance, your CAC from paid ads might be significantly higher than from organic search or referrals.
Why tracking customer acquisition cost is essential for your business
Keeping a close eye on Customer Acquisition Cost (CAC) is vital to sustainable success. CAC represents the cost of converting a prospect into a paying customer, and tracking this metric consistently can make or break your growth strategy. Here’s why tracking customer acquisition cost matters for your business:
CAC as a core performance metric
Customer acquisition cost (CAC) shows how efficiently your business converts spend into customers. For SaaS companies, CAC tends to be higher due to longer sales cycles and the need for education. In contrast, e-commerce brands usually have lower CAC thanks to quicker decision-making.
No matter your model, CAC is central to understanding your marketing ROI. It tells you if your growth is sustainable, or if you’re spending too much for too little in return.
Impact on profitability, forecasting, and growth
Tracking CAC ensures your acquisition efforts stay profitable. If it costs more to acquire a customer than they’re worth, your business model needs adjusting.
Knowing your CAC also improves planning. For example, if your average CAC is $250 and you aim to acquire 1,000 customers, you can forecast a $250,000 budget. It also helps spot channel-level inefficiencies, so you can shift spend to what works. In short, CAC isn’t just a marketing metric; it’s a financial signal that guides budget, targeting, and future growth.

Average customer acquisition cost by industry: 2025 benchmarks
Understanding how your acquisition costs compare to industry norms is critical for evaluating performance, setting budgets, and optimizing spend. Whether you’re running a SaaS startup or an e-commerce brand, knowing the average customer acquisition cost (CAC) in your sector helps you determine if you’re overspending or uncovering a competitive advantage. Below, we break down CAC benchmarks across key industries, with a focus on B2B vs B2C models, SaaS platforms, and online retail brands.
CAC benchmarks for B2B vs B2C sectors
Customer acquisition costs vary widely across industries, and the difference between B2B and B2C models is particularly stark. B2B companies tend to have higher CAC due to longer sales cycles and more complex buyer journeys, while B2C brands often benefit from shorter purchase decisions and broader reach through paid media.
- B2B SaaS: ~$702 per customer
- Commercial Insurance: $900+
- Higher Education: $1,100+
- Legal Services: $1,150–$1,300
In contrast, B2C businesses generally operate with lower CAC:
- Beauty and Body Treatment: ~$61
- Fashion & Apparel: ~$66
- Electronics: ~$76
- Jewelry: ~$91
- Food & Beverage: ~$53
Understanding where your business falls within these industry averages helps you benchmark performance and identify whether your acquisition strategy is under- or overspending for the results it’s delivering.
What is the average customer acquisition cost for SaaS?
The average customer acquisition cost for SaaS businesses typically ranges from $200 to over $700, depending on the vertical and sales model:
- General SaaS: ~$702
- eCommerce SaaS: ~$274
- Legaltech SaaS: ~$299
- Fintech SaaS: Up to $1,450
These elevated costs reflect the longer sales cycles, product education requirements, and personalization that define most SaaS customer journeys. Tracking CAC is critical for SaaS teams, not just for budgeting, but for maintaining a healthy LTV: CAC ratio as they scale. With Usermaven, SaaS companies can break down CAC by channel and campaign in real time, giving teams the insights needed to drive efficient growth.
What is the average customer acquisition cost for e-commerce brands?
E-commerce brands tend to have lower average CAC, but performance can vary significantly based on product type, price point, and customer retention strategy:
- Food & Beverage: ~$53
- Beauty and Body Treatment: ~$61
- Fashion & Apparel: ~$66
- Electronics: ~$76
- Jewelry: ~$91
While these numbers are generally lower than SaaS, the margins in e-commerce are often tighter. That makes tracking CAC, alongside return rates and customer lifetime value, critical to profitability. With Usermaven, e–commerce marketers can monitor CAC by source, optimize campaign spend, and build more profitable acquisition strategies without relying on siloed data.

How to improve your customer acquisition cost
Lowering your customer acquisition cost doesn’t mean slashing budgets; it means making your acquisition efforts more efficient. From optimizing your funnel to leveraging automation and long-term content strategies, here are proven ways to reduce CAC and drive profitable growth.
1. Funnel optimization and conversion rate improvements
Improving your conversion rates is one of the most direct ways to lower CAC. Even small changes to landing pages, onboarding flows, or checkout experiences can lead to significant gains in customer acquisition without increasing your spend.
For example, A/B testing headlines, CTAs, or pricing displays can help move more users through the funnel. In e-commerce, simplifying the checkout process can dramatically boost conversion rates. For SaaS, removing friction in trial signups or demo booking forms can reduce drop-off and increase lead-to-customer conversion.
Usermaven allows you to track each funnel stage, helping you identify where prospects are stalling and where optimizations will have the most impact.
2. Smart audience targeting and retargeting strategies
Refining who sees your ads directly improves your CAC. By using highly segmented targeting based on behavior, demographics, and intent, you can reduce wasted spend and focus on users most likely to convert.
Retargeting is another high-leverage tactic. Visitors who already know your brand often convert at 2–3× higher rates than cold traffic. Whether through email, display ads, or social, retargeting keeps your brand top-of-mind while improving conversion efficiency.
With Usermaven’s attribution and segmentation tools, you can identify high-performing audiences and allocate your budget to what works.
3. Marketing automation and referral systems
Marketing automation reduces CAC by minimizing manual effort across the funnel. Automated email sequences, lead-nurturing workflows, and behavior-based messaging help move prospects toward conversion without requiring extra team bandwidth.
Referral programs are another efficient channel. Customers acquired through referrals often have 20–40% lower CAC and higher lifetime value. Offering incentives for both referrer and referee encourages participation and drives cost-effective growth.
Usermaven helps you track the CAC impact of automated sequences and referral campaigns, ensuring they perform at scale.
4. Content-led acquisition to reduce long-term CAC
Content marketing is one of the most sustainable ways to lower CAC over time. Educational blog posts, SEO-optimized landing pages, product tutorials, and downloadable resources build organic traffic and authority, driving leads without ongoing ad spend.
For SaaS businesses, in-depth guides and case studies attract high-intent prospects. For e-commerce, content around lifestyle, product use, or trends can boost engagement and drive traffic to product pages.
Unlike paid ads that stop performing the moment the spend ends, great content continues to deliver traffic and conversions long after it’s published. Usermaven helps measure how content contributes to CAC reduction through multi-touch attribution and funnel tracking.

FAQs about average customer acquisition cost
What is considered a good CAC in 2025?
A “good” CAC depends on your business model and industry. The key benchmark is your LTV: CAC ratio; aim for at least 3:1. For example, if a customer is worth $900 over their lifetime, spending $300 or less to acquire them is considered sustainable. SaaS businesses may accept higher CAC if retention is strong; e-commerce brands typically need lower CAC due to thinner margins.
How often should you track your CAC?
You should track CAC continuously, not just monthly or quarterly. Real-time tracking allows your team to catch inefficiencies early and make fast adjustments. With tools like Usermaven, you can monitor CAC daily by campaign or channel, enabling more agile decisions.
Does a lower CAC always mean better performance?
Not always. A very low CAC might indicate underinvestment or missed growth opportunities. What matters most is the balance between CAC and customer lifetime value (LTV). If your CAC is too low but LTV is also low, you’re not maximizing revenue potential. Aim for a healthy LTV: CAC ratio rather than chasing the lowest CAC.
Can CAC be calculated per channel?
Yes, CAC should be calculated per channel. Calculating CAC per channel helps you understand which acquisition sources are most efficient. For example, your CAC from email marketing may be far lower than from paid social.
