Understanding Customer Acquisition Cost

CAC is one of the most important metrics for any business. It tells you how much you're spending to acquire each new customer.

Formula: CAC = Total Acquisition Costs / New Customers
Healthy CAC:LTV Ratio: 1:3 or higher (LTV should be 3x CAC)
Break-even: CAC equals first purchase value
Include in costs: Marketing, sales salaries, commissions, tools, and overhead

Tip: Track CAC by channel to identify your most efficient acquisition sources. Aim to reduce CAC over time through optimization.

Frequently Asked Questions

How do I calculate customer acquisition cost?

CAC is calculated by dividing total acquisition costs by new customers acquired. Formula: CAC = (Marketing Spend + Sales Spend + Other Costs) / New Customers. For example, spending $10,000 to acquire 100 customers gives a CAC of $100.

What is a good CAC to LTV ratio?

A healthy CAC:LTV ratio is 1:3 or higher, meaning customer lifetime value is at least 3x the acquisition cost. Ratios below 1:1 indicate you're losing money on each customer. SaaS companies typically target 1:3, while e-commerce may accept 1:2.

What costs should be included in CAC?

Include all marketing expenses (ads, content, events), sales costs (salaries, commissions, tools), and related overhead. Don't forget software subscriptions, agency fees, and creative production costs that support customer acquisition.

How can I reduce my customer acquisition cost?

Reduce CAC by improving conversion rates, optimizing ad targeting, leveraging organic channels (SEO, content, referrals), increasing customer retention, and focusing on high-ROI marketing channels. Test and iterate constantly.

What is the payback period for CAC?

CAC payback period is how long it takes to recover acquisition costs from a customer. Calculate by dividing CAC by average monthly revenue per customer. SaaS companies typically target under 12 months payback for healthy cash flow.
