Calculate your customer acquisition cost, lifetime value, and payback period
Customer acquisition cost (CAC) is the total sales and marketing spend divided by new customers acquired. A healthy SaaS business should have an LTV:CAC ratio of at least 3:1, meaning each customer generates 3x more lifetime revenue than it costs to acquire them. This free CAC calculator computes your customer acquisition cost, lifetime value, LTV:CAC ratio, and payback period — with a health verdict telling you if your unit economics are sustainable.
