Claims Ratio

The Claims Ratio measures total claims incurred in a period divided by the earned premium for that same period. It tells insurers whether the premiums collected are sufficient to cover what's being paid out.

What is Claims Ratio?

Claims Ratio is the percentage of earned premium paid out as claims over a given period. A high ratio signals that claims costs are eating into premium income; a low ratio may point to pricing misalignment or barriers that prevent legitimate claims from being filed.

Why Claims Ratio matters

For any insurance leader, Claims Ratio is one of the clearest signals of whether the business is priced and managed correctly. It connects underwriting decisions, product design, and claims operations into a single number you can track over time.

When Claims Ratio rises above expected norms, it usually points to one of a few problems: adverse selection in the customer base, fraud, or a pricing model that no longer reflects actual risk. When it falls unusually low, the concern shifts. Products may be poorly matched to customer needs, or the claims process may be difficult enough that policyholders aren't filing what they're entitled to. Both outcomes carry risk, just in different directions.

Tracking this metric consistently gives you the early warning you need to act before a trend becomes expensive.

How to calculate Claims Ratio

Claims Ratio = (Claims Incurred / Earned Premium) × 100

Claims Incurred includes all claims paid during the period plus any movement in outstanding claims reserves. Earned Premium is the portion of written premium that applies to the period being measured, not the full policy value.

Example

An insurer collects $10,000,000 in earned premium over a quarter and incurs $6,200,000 in claims.

Claims Ratio = ($6,200,000 / $10,000,000) × 100 = 62%

A 62% Claims Ratio means 62 cents of every premium dollar went to claims costs. Whether that's acceptable depends on the line of business, expense structure, and target Combined Ratio.

What is a good Claims Ratio?

There is no universal benchmark. Claims Ratio norms vary significantly by line of business, geography, and business model. Personal auto insurance typically runs higher than commercial property; health insurance higher still.

What matters most is consistency with your own targets and awareness of movement over time. A Claims Ratio that is stable and within your pricing assumptions is manageable. One that is trending upward quarter over quarter demands investigation.

As a general reference point, many property and casualty insurers aim to keep Claims Ratio below 70%, leaving room for expenses and a margin for underwriting profit. Combined with the Expense Ratio, the two figures make up the Combined Ratio, the most complete measure of underwriting profitability.

Claims Ratio and related insurance metrics

Claims Ratio does not stand alone. It becomes most useful when tracked alongside:

• Loss Ratio: Often used interchangeably with Claims Ratio, though Loss Ratio sometimes includes loss adjustment expenses. Confirm which definition your team uses before comparing across sources.
• Combined Ratio: Claims Ratio plus Expense Ratio. A Combined Ratio below 100% means the business is profitable on underwriting. Above 100%, premiums are not covering total costs.
• Claims Settlement Ratio: The proportion of claims settled against total claims received. A low settlement ratio can mask a Claims Ratio that looks healthy on paper while flagging an operational problem.
• Policy Renewal Rate: Persistent claims friction, whether too many denied or too slow to resolve, tends to show up in renewal rates before it appears elsewhere.

How to track Claims Ratio

Calculating Claims Ratio once is straightforward. Tracking it reliably across time periods, business lines, and geographies is where most teams run into friction. Pulling figures from separate systems, reconciling period definitions, and rebuilding the same calculation every month adds up.

A dashboard that connects directly to your data sources and refreshes automatically means you see the current number without having to go looking for it. When Claims Ratio moves, you know immediately, and you have the context to understand why. Klips connects to 130+ data sources and lets you build insurance dashboards that surface these metrics in real time, so your team is always working from the same reliable numbers.
