Policy renewal rate is the percentage of policies that renew at the end of their term rather than lapsing or being replaced by a competitor.

Renewal rate is the compound interest of insurance economics. A 90% renewal rate versus an 85% renewal rate doesn't sound like much, but over five years it's the difference between retaining 59% of your book versus 44%. Acquisition costs mean the lifetime value of a renewed policy far exceeds a new policy of equivalent premium.

The claims experience is the single largest driver of renewal rate. Policyholders who never file claims renew based on price and inertia. Policyholders who file claims renew—or don't—based on how that experience felt. A smooth, fast, empathetic claims process creates fierce loyalty; a frustrating one sends customers to competitors who haven't yet failed them.

Measuring renewal rate alone isn't enough. Segment by profitability: are you retaining your best risks or your worst? A high renewal rate on unprofitable segments accelerates losses. Pair renewal rate with retention of premium weighted by loss ratio to understand whether your retention is actually valuable.
