The loyalty penalty: why you should shop your auto and home insurance
The short version: Auto and home insurers increasingly price loyalty as a cost, not a reward — how long you have been a customer becomes its own rating input, and it tends to push your renewal up. Insurers do it because inertia is measurable: customers who have stayed for years are less likely to leave over an increase, so they can be charged closer to what they will tolerate. The defense is simple, and it works here because switching auto or home coverage is cheap and frictionless: collect fresh quotes every renewal or two, and actually move when a competitor comes in lower. The filing that prompted this — a Donegal private-auto rule filing covering 22,000-plus Pennsylvania policyholders — is one documented example sitting on a public docket.
Most people treat their auto and home policies as set-and-forget. You picked a carrier once, the renewal shows up every term, you pay it. The quiet assumption is that staying loyal earns you something — a steady rate, the benefit of the doubt. For a growing share of insurers, the opposite is true: your tenure is itself a reason to charge you more.
Loyalty as a line item
The industry term is "price optimization." Instead of pricing strictly to your risk — your driving record, your home, your ZIP — an insurer also prices to your behavior as a customer: how likely you are to shop around and leave. Carriers can model that likelihood from years of data, and once modeled it can be built into the rate. Customers who have renewed without complaint for years have shown they probably won't bolt over a few more percent, so the increase lands on them a little harder. New customers, who are actively comparing, get the sharper price to win the sale.
It is the reverse of how loyalty is supposed to work, and it is not a rumor — it is written into rate and rule filings that regulated insurers submit to state insurance departments before those prices can touch a policy. Those filings are public records.
What the filing on the docket looks like
The example that prompted this piece is DNGL-134452278, a private passenger auto Rate/Rule filing from Southern Insurance Company of Virginia, part of the Donegal group. Submitted to the Pennsylvania Insurance Department in March 2025 and closed that May, it governs a book of roughly $27 million in written premium across 22,279 policyholders. A rule filing like this is where the machinery lives — the factors and tiering logic that decide how an individual driver's renewal is built, tenure among them. The headline "average rate change" can be modest or even zero while the structure underneath quietly redistributes who pays what.
That gap between the headline and the structure is the whole reason to read past the average. A filing can advertise a small overall change while moving specific customers — often the long-tenured ones — by considerably more.
Why shopping actually works for these policies
The reason the standard advice — shop around, switch — works so cleanly for auto and home is that there is almost no cost to leaving. Coverage is fungible: a competitor writes you essentially the same policy starting tomorrow, your claims history follows you, and nothing about having been with your old carrier makes the new one charge you more. The only thing you give up by switching is the loyalty penalty itself.
That asymmetry is the entire opportunity. The insurer is betting you won't look. The moment you do — and act on it — the model that priced your inertia is simply wrong about you, and you land back in the new-customer pricing the carrier uses to win business. Shopping isn't a hassle tax you pay for a small edge; it is the one move that directly defeats the thing inflating your bill.
How often, and what to watch
Get fresh quotes at least every renewal or two, and pay attention to the trend rather than any single bill: the loyalty penalty shows up as a rate that keeps drifting up faster than your risk has changed — no tickets, no claims, no new teenage driver, and still a steady climb. That drift is the tell. When you quote out and a comparable competitor comes in meaningfully lower for the same coverage, that difference is largely the penalty, and the fix is to take the lower one.
Regulators have noticed. A number of states have issued guidance or rules against price optimization specifically because charging customers based on how captive they are — rather than on their risk — strains the basic promise that rates be cost-based. But enforcement is uneven from state to state, so the practical defense is still yours to run: shop, and be willing to move.
You can see who is raising rates in your state, and by how much, ahead of the notice in your mailbox — compare filings side by side in the filing comparison tool, or watch a carrier and get an email the moment it files something new with rate alerts. The carrier that was cheapest when you signed up is rarely still the best deal.
