What Is Retention Rate?

Retention is agency gravity: high retention compounds a book, weak retention makes every year a rebuild. Commercial retention runs high by consumer-business standards because switching is genuinely costly for the insured, re-shopping coverage means re-submitting, re-underwriting, and re-learning a relationship, and because rounding multiplies that switching cost line by line.

But retention is earned at specific moments, and the x-date is the biggest one. Every account in your book carries a date when a competing producer can legitimately contest it, which is why the same data infrastructure that powers your prospecting (expiration dates, carrier and premium history) powers competitors aiming at your renewals. The 2025-2026 softening sharpened both edges: CIAB documented carriers getting more aggressive on large accounts as rates decelerated, which means shopping is back, in both directions.

The planning use is simple: revenue retention tells you the leak; the leak tells you the new-business quota; the close rate tells you the meetings that quota requires.
