In any insurance renewal, your claims history moves the price before an underwriter (the person at the carrier who decides your terms) weighs anything else. Carriers read your recent claims record to set that renewal number. It lists what you've filed and what each claim cost. For a brand doing $1M to $100M in sales, one open claim sitting in reserve can raise the premium more than a full year of clean operations.
The carriers that renewed your last policy and the ones competing for it this year all start with the same file. That file is part of your annual insurance audit, the review your whole renewal hangs on.
A claims record, often called a loss run, is the report your carrier produces listing every claim on your policy and what each one cost. At renewal, the underwriter treats that record as the factual baseline for pricing your account and deciding whether they'll offer terms at all.
The International Risk Management Institute defines a loss run as periodic reports of claim information an insurer provides to the insured. It's your policy's track record. Each line shows a claim's date, what happened, and how much the carrier paid to close it. For an open claim, it also shows how much money the insurer set aside to pay it later, a figure IRMI calls a loss reserve.
An open claim sitting in reserve moves the renewal number more often than founders expect. The carrier prices off what the file could still cost, even if the final payout turns out far lower. That's why the claims record weighs so heavily in what drives your renewal premium.
Most carriers pull three to five years of claims history at renewal. That window is long enough to show a pattern and short enough to reflect how you run the business today. A single bad year carries less weight than the same problem repeating across all five years. Underwriters price against patterns, not one-offs.
When an insurer requests your loss run report ahead of a renewal, it usually asks for several years so it can judge the risk and set the price. On the personal side, home and auto loss history reports reach back five years per the Insurance Information Institute, and commercial loss runs follow the same pattern. Older claims still appear, but they fade as they near the edge of that window.
If a rough year is about to drop off the back of a five-year look, waiting to shop can work in your favor. Most founders never check. Where does your worst claim sit in that window? It's one of the cheapest things to get right.
Carriers turn your claims history into two numbers, a loss ratio and an experience modifier. Loss ratio compares what the insurer paid out to what you paid in premium. The experience modifier compares your losses to what similar businesses are expected to file, then adjusts your rate up or down. Both are drawn from the same claims record.
Your loss ratio stacks what the insurer paid on your claims against what you paid in premium. IRMI expresses it as a percentage: a business paying $100,000 in premium whose insurer pays and reserves $50,000 in claims runs a 50% loss ratio. Push that ratio to 80% and the carrier is losing money on your account. A rising loss ratio is often the real reason a renewal climbs.
Experience rating goes a step further. Carriers compare your actual losses to the losses expected for your rating class, then apply a modification factor to your premium, per IRMI. A better-than-expected record lowers that factor and your rate, while a worse one raises both.
If your renewal jumped without a new claim, it's almost certainly a market-wide increase. That's a big reason premiums climbed in 2026 even for brands with clean records.
Frequency (how often you file) and severity (how large each claim runs) worry carriers for different reasons. A string of small, frequent claims can concern a carrier as much as one big loss. Frequency tells a carrier there's an ongoing problem. Severity signals the account can produce a catastrophic hit.
IRMI rates loss frequency on a low-to-high scale. General liability (the policy that covers third-party injuries and property damage) claims usually land at moderate frequency; property losses at low. The distinction matters because four small slip-and-fall claims in two years look like a habit to the underwriter pricing your renewal, while one $400,000 product-liability loss reads as rare but proof of real exposure.
(A brand with five $2,000 claims often renews worse than a brand with one $30,000 claim, even though the second cost the insurer more.) Frequency is the harder story to tell at renewal, because it suggests an ongoing pattern the carrier expects to continue.
A clean claims record works harder for you at renewal than almost anything else you control. It lowers your loss ratio and improves your experience modifier, which gives your broker room to shop the account to carriers that reward good history. It won't cancel a market-wide rate increase, but it's what keeps your number below the pack when rates rise for everyone.
A clean record also opens options, because carriers compete harder for an account that hasn't cost them anything. That competition gives a broker room to shop the renewal harder. It's also the right moment to check whether a limit that has grown too thin should move up while your record still earns the best terms available.
If a renewal still comes back high despite a clean record, that record travels. A new carrier underwrites the same loss history, which makes it easier to switch carriers mid-term without losing pricing credit for your good years.
Present your claims history well by pulling your loss runs early and checking them for errors. Attach a short note on what you fixed after any claim. Carriers price off the file in front of them, so a corrected record and a documented fix can lower the renewal before you ever negotiate the number.
The renewal file you hand a carrier can still change before the quote lands:
When Coverwatch takes an ecommerce account to renewal, the claims record goes to market with a short written summary of what changed after each loss. An underwriter who sees the fix tends to price the risk lower than one who sees only the claim. Once quotes come back, compare the renewal quotes on coverage terms first, then price.
A flat-fee broker earns the same fee whether your premium rises or falls, so there's every incentive to make your claims history work for you. Coverwatch markets ecommerce programs across 60+ carriers and packages your loss runs and remediation notes so carriers see the remediation alongside the loss, which in our accounts typically holds the increase below the market-average rate movement. See ecommerce insurance for scaling brands to review your renewal before the next expiration date.
Your claims history is the main input a carrier uses to price a renewal. The insurer reads your claims record and turns it into a loss ratio and an experience modifier. It then adjusts your rate up or down based on how your losses compare to what similar businesses file. A clean record lowers the price; frequent or large claims raise it or can lead to non-renewal.
Most carriers request three to five years of claims history at renewal. That window is long enough to reveal a pattern and short enough to reflect how you run the business now. Older claims still show up but count for less as they age toward the edge of the window.
They can, even before they pay out. An open claim carries a reserve, the amount the insurer set aside to settle it. That reserve counts toward your loss ratio as if it were already paid. If a claim is overstated or should be closed, ask your broker to have the reserve corrected before the underwriter prices your renewal.
Not automatically. Carriers look at frequency and severity across three to five years. One claim inside a mostly clean record has limited impact, especially if it was a one-off you've since fixed. A repeating pattern of small claims, or one very large loss, moves the price far more than a single isolated claim.
Yes, in a few ways. Correct any errors on your loss runs, confirm open-claim reserves are realistic, and attach a short remediation note explaining what changed after each loss. A documented fix helps an underwriter price the risk lower, and a broker can shop a corrected record to carriers that weigh recent improvement more heavily.
