Your retention rate is 90.0% - excellent - typical of top-performing B2B SaaS and enterprise software businesses.

  • You retained 900 out of 1,000 existing customers, losing 100 this period.
  • At a 10.0% churn rate, the average customer stays for about 10.0 years before leaving.
  • Your customer lifetime value is roughly $12,000 per customer - meaning each new acquisition you keep is worth that over their lifetime.

Next stepAt this level, focus on expansion revenue: upsells, cross-sells, and multi-year contracts can compound revenue without acquiring a single new customer.
