About This Calculator
Customer Acquisition Cost (CAC) is one of the most important metrics for any business. It measures how much it costs to acquire a new customer. Use this calculator to determine your CAC, compare it with CLV, and understand your payback period.
Tracking CAC helps businesses optimize their marketing spend, improve sales efficiency, and ensure sustainable growth. A healthy business typically has an LTV:CAC ratio of 3:1 or higher.
Frequently Asked Questions
What is Customer Acquisition Cost?
Customer Acquisition Cost (CAC) is the total cost of acquiring a new customer, including all sales and marketing expenses. It is calculated by dividing total sales and marketing costs by the number of new customers acquired. CAC helps businesses evaluate the efficiency of their customer acquisition strategies.
What is a good CAC?
A good CAC varies by industry but should generally be recovered within 12 months of customer revenue. The LTV:CAC ratio should be at least 3:1. For SaaS businesses, a CAC under ₹5,000 ($500) is considered good. For enterprise SaaS, CAC can be ₹50,000+ ($5,000+).
How to calculate CAC?
CAC = Total Sales & Marketing Costs / Number of New Customers Acquired. For example, if you spend ₹5,00,000 on sales and marketing and acquire 100 new customers, your CAC is ₹5,000 per customer. Include all costs: salaries, advertising, tools, and overhead.
How to reduce customer acquisition cost?
Reduce CAC by optimizing marketing channels (focus on highest ROI channels), improving conversion rates through A/B testing, leveraging organic marketing (SEO, content), implementing referral programs, improving sales team efficiency, targeting high-intent audiences, and automating lead qualification.
What is the difference between CAC and CPA?
CPA (Cost Per Acquisition) typically refers to the cost of a single conversion in a specific marketing campaign. CAC is broader, encompassing all sales and marketing costs across all channels to acquire a paying customer. CAC gives a more complete picture of acquisition efficiency.
How does CAC relate to payback period?
The payback period is how long it takes to earn back the CAC from customer revenue. It is calculated as CAC / (Monthly Revenue per Customer - Monthly Service Cost). A shorter payback period (ideally under 12 months) means faster return on acquisition investment and healthier cash flow.
