Calculate your Customer Acquisition Cost (CAC) and see how it compares to LTV for a sustainable growth model.

Practical example: $27K S&M spend, 50 new customers. For a early-stage saas scenario, enter the values that match your situation to get an instant cost estimate.

What is a good CAC for SaaS? There's no universal "good" CAC — it depends entirely on your LTV. The key metric is LTV:CAC ratio. SaaS businesses should target at least 3:1 (LTV 3× higher than CAC). If your LTV is $1,500 and CAC is $300, that's a healthy 5:1 ratio.

Formula: totalSpend = salesMarketingSpend + salesSalaries + marketingTools. CAC = totalSpend / newCustomers. costPerLead = CAC / 5 (assumes 5:1 lead-to-customer ratio)
