What it means
The claims ratio, also called the loss ratio, compares claims incurred in a period with premiums earned in that same period. Both are earned figures rather than cash figures, meaning they relate to the period of cover rather than to when money happened to move.
For an insurer the ratio separates two very different problems: mispricing risk and overspending on running the business. A high claims ratio says the policies were sold too cheaply or the risk was assessed badly, and no amount of cost cutting elsewhere will repair that.
Analysts pair it with the expense ratio, which measures commissions, administration and acquisition costs against the same premium base. Add the two together and you get the combined ratio, where anything under 100% means the underwriting business made money before any investment income is counted.
Reported ratios move around because claims are estimated long before they are finally settled, so a reserve top-up in one year can inflate a ratio that really belongs to an earlier one. Businesses outside insurance borrow the idea too: warranty providers, extended service plan sellers and self-insured employers all track claims against the fee they charged.
Different lines of business carry very different normal ranges, so the number only means something when set against comparable peers. Motor and health cover often run claims ratios somewhere in the 70% to 85% band, while some specialty lines sit far lower because their expense loads are much heavier.
In practice
Real-world examples.
Example
A health insurer reviews its small business product and finds a claims ratio of 92%, up from 78% two years earlier. Because the expense ratio is a steady 14%, the combined ratio is now 106% and the product loses money on every policy sold. Pricing is raised at renewal and two high-claim occupations are moved into a separate rating band.
Example
A retailer sells extended warranties on appliances and tracks them like an insurance book. It collects $3,000,000 in warranty fees and pays $1,200,000 in repair claims, a claims ratio of 40%, which tells the finance director the product is a genuine profit centre rather than a customer service add-on.
Example
A regional insurer reports a claims ratio of 68% at the half year, then 81% for the full year after a storm season. The board asks for the ratio to be shown both including and excluding catastrophe claims, so it can see the underlying pricing trend separately from weather.
Think of it
“Claims ratio shows claims relative to premiums-how much is going out versus coming in.
Formula
Calculation
Claims Ratio = (Claims Incurred / Premiums Earned) x 100
A mid-sized motor insurer earns $9,000,000 of premiums in a year. Claims incurred over that year, including an estimate for claims reported but not yet settled, come to $6,300,000.
Claims Ratio = ($6,300,000 / $9,000,000) x 100 = 70%
Its operating expenses, commissions and policy administration total $2,250,000, giving an expense ratio of ($2,250,000 / $9,000,000) x 100 = 25%. The combined ratio is 70% + 25% = 95%, so the insurer made an underwriting profit of $9,000,000 - $6,300,000 - $2,250,000 = $450,000, which is 5% of premiums earned. If claims incurred had instead come in at $7,200,000, the claims ratio would be 80%, the combined ratio 105%, and the book would have lost $450,000 before investment income.Case study
Seen in the real world.
In this illustrative example, Harbourline Mutual is a fictional insurer writing cover for small commercial fishing fleets. It had grown premiums by 30% over two years by matching a competitor's rates, and management treated the growth as evidence the pricing worked.
The finance team split the claims ratio by vessel age and found that the overall figure of 79% hid two very different books: vessels under ten years old ran at 61%, while older vessels ran at 106%. The older segment was 40% of premiums but was consuming about 54% of all claims spending.
Harbourline kept its rates for newer vessels, repriced older ones and introduced a mandatory survey above fifteen years of age. Eighteen months later the blended claims ratio had come back to 71% and premium volume had fallen only slightly, because most of the business it lost was the business that had been losing money.
Watch out
Common mistakes.
- Comparing the claims ratio with cash paid out during the year. The ratio uses claims incurred, which includes an estimate of claims that have happened but have not yet been settled or even reported.
- Assuming a low claims ratio always means a good product. A very low ratio can mean the cover is so restrictive that customers rarely claim, which usually shows up later as poor renewal rates and regulatory attention.
- Judging an insurer on the claims ratio alone. Without the expense ratio you cannot tell whether the business is profitable, because a 65% claims ratio paired with a 40% expense ratio still loses money.
Questions
People also ask.
Is the claims ratio the same as the loss ratio?
Yes, the two terms are used interchangeably in most markets, though some insurers reserve loss ratio for claims before reinsurance recoveries.
Why can the claims ratio change after the year has closed?
Because reserves for open claims are estimates, and when those claims settle for more or less than expected the difference is booked in a later period.
What is a good claims ratio?
It depends entirely on the line of business and the expense load, but a common working test is whether the claims ratio plus the expense ratio stays comfortably below 100%.
