A breakdown of what direct and indirect costs we must include in our CAC calculation. 3. A checklist of metrics we need to track in our analytics dashboard to continuously monitor these figures. 4.

Example Output
For your subscription box startup priced at forty dollars per month with a five percent monthly churn rate, your lifetime value formula is monthly revenue divided by churn rate. Your average customer lifetime is twenty months, making your gross lifetime value eight hundred dollars. To compute your customer acquisition cost, combine your total ad spend, agency fees, and marketing salaries, then divide by new customers acquired. To hit a healthy three-to-one ratio, your acquisition cost must stay under two hundred sixty dollars. You can optimize this by setting up automated referral emails on successful deliveries.
