High retention means you've built something people want. Low retention means you haven't — no matter how good your acquisition looks. TenScore weights retention at 20% because it's that important.
TenScore measures retention through session_started events. If a user returns and starts a new session, they're retained. We calculate week-over-week return rates and benchmark against healthy SaaS products.
It depends on your product type. B2B SaaS typically sees 80-90% monthly retention. Consumer products might be 30-40%. TenScore benchmarks against your product category, not a universal standard.
Retention is the clearest signal of product-market fit. Users who come back have found value. Users who don't haven't. It's weighted equally with activation because both are essential to product health.
