Your claims history is the single biggest lever in an insurance renewal, and it moves the premium before an underwriter weighs anything else. Carriers read your recent claims record, the report of what you have filed and what it cost, to decide whether to renew you and at what price. For a brand doing $1M to $100M in sales, one open claim still sitting in reserve can raise the number more than a full year of clean operations.
This guide covers how carriers read your claims history at renewal and how many years they pull. You will also see why frequency and severity read differently, and how to present your record so a clean year earns a lower rate. It sits inside your annual insurance audit, the review the whole renewal hangs off.
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 to 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. In plain terms, it is 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.
Across the ecommerce renewals Coverwatch reviews, an open claim sitting in reserve moves the renewal number more often than founders expect, because the carrier prices off what the file could still cost, not what it has paid so far. That is one reason the claims record does so much to shape what drives your renewal premium in the first place.
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 still reflect how you operate today. A single bad year inside it carries less weight than the same problem repeating across all of it, which is what underwriters really price against.
When an insurer requests your loss runs, it usually asks for several years of claims history so it can judge the risk and set the price. On the personal side, the equivalent home or auto loss history report reaches back five years, per the Insurance Information Institute. Commercial loss runs work the same way: older claims still appear, but they fade as they age toward 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 their worst claim sits in that window before renewal, and it is 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 drawn from the same claims record.
Loss ratio is incurred losses divided by earned premium, expressed as a percentage, per IRMI. A business paying $100,000 in premium whose insurer pays and reserves $50,000 in claims runs a 50% loss ratio. Carriers want that ratio well under the point where the account stops making money, and a rising loss ratio is often the real reason a renewal climbs.
Experience rating goes a step further than loss ratio. 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, the increase is usually market-wide rather than yours. That is a large part of why premiums climbed in 2026 even for brands with clean records.
Both hurt a renewal, but they signal different things. Frequency is how often you file a claim. Severity is how large each claim runs. A string of small, frequent claims can worry a carrier as much as one big loss. Frequency suggests an ongoing problem, while severity signals the account can produce a catastrophic hit.
Insurers weigh frequency and severity as two separate signals. Frequency is the likelihood a loss happens, rated low, moderate, or high; general liability claims usually sit at moderate frequency and property losses at low, per IRMI. Severity is the size of the damage when it does happen. Four small slip-and-fall claims in two years read as a pattern an underwriter expects to continue, 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 looks like a habit rather than an accident.
A clean, claim-free record is the strongest thing you bring to a renewal. It lowers your loss ratio, improves your experience modifier, and gives your broker room to shop the account to carriers that reward good history. It will not cancel a market-wide rate increase, but it is 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 has not cost them anything. That competition gives a broker room to shop the renewal harder. It is 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.
Presenting your claims history well means pulling your loss runs early, checking them for errors, and attaching 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.
Three moves make the difference:
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, because an underwriter who sees the fix tends to price the risk below one who sees only the claim. Once quotes come back, compare the competing renewal quotes on coverage, not just on price.
A flat-fee broker earns the same fee whether your premium rises or falls, so the incentive is to make your claims history work for you. Coverwatch markets ecommerce programs across 60+ carriers and packages your loss runs and remediation notes so a clean or improving record gets priced fairly. 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, turns it into a loss ratio and an experience modifier, and adjusts your rate up or down based on how your losses compare to what similar businesses are expected to 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, and 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, so one claim inside a mostly clean record has limited impact, especially if it was a one-off you have 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.
