Customer Acquisition Cost (CAC) is the total cost of acquiring a new customer, calculated by dividing total sales and marketing expenses by the number of new customers acquired in a given period. CAC is one of the most important SaaS business metrics because it determines the unit economics of growth — how much you spend to acquire each dollar of revenue.
CAC determines whether a business can grow profitably. If it costs more to acquire a customer than they’ll ever pay you, the business model is fundamentally broken. For channel-focused companies, CAC through partners is typically 30-50% lower than direct CAC because partners bring existing relationships, local credibility, and shared marketing costs. Understanding CAC by channel helps optimize growth investment.
Cost of internal sales team divided by customers they close directly.
Advertising, content, events, and demand gen spend divided by marketing-sourced customers.
Partner program costs (enablement, MDF, incentives, channel team) divided by partner-sourced customers.
Total sales + marketing + channel spend divided by all new customers regardless of source.
Time required for a customer’s revenue to recover the cost of acquiring them.
The ratio of acquisition cost to lifetime value — healthy SaaS companies target 1:3 or better.
Calculate CAC separately for direct, marketing-sourced, and partner-sourced customers.
Target a CAC:LTV ratio of 1:3 or better — below 1:1 is unsustainable, above 1:5 suggests underinvestment.
Include all channel program costs in partner CAC — not just commissions but also enablement, tools, and channel team salaries.
Track CAC trends over time — rising CAC signals channel saturation or competitive pressure.
Invest in channels with the lowest CAC that deliver acceptable customer quality and retention.

CAC = Total Sales & Marketing Spend / Number of New Customers Acquired. For accuracy, calculate separately for each channel: direct, marketing, and partner-sourced.
It depends on your average contract value. The benchmark is a CAC:LTV ratio of 1:3 or better and a payback period under 12 months. Enterprise SaaS tolerates higher absolute CAC because deal sizes are larger.
Partners bring existing customer relationships (no cold outreach cost), share marketing expenses through MDF co-investment, and provide local credibility that shortens sales cycles. Partner-sourced CAC is typically 30-50% lower than direct.
