The One Metric 90% of Startups Ignore (But Shouldn't)

Most founders obsess over revenue or CAC but miss a critical metric: **Customer Retention Cost (CRC)**. Here’s why it matters:

- Acquiring a new customer costs 5–25x more than retaining one (Harvard Business Review). - A 5% increase in retention boosts profits by 25–95% (Bain & Co).

**How to Calculate CRC**: 1. Add up all retention expenses (loyalty programs, support, etc.) over a period. 2. Divide by number of retained customers in that period.

**Actionable Fixes**: - Automate onboarding (try [Mailchimp](https://mailchimp.com) workflows) - Send personalized check-ins (e.g., “How’s [product] working for you?”) - Surprise loyal customers with handwritten notes or small upgrades

Example: A SaaS client reduced CRC by 40% just by adding a 2-minute tutorial video to their welcome email. What’s your retention secret?
