Insurance, explained

Loss ratio

Loss ratio compares claims costs with a defined premium measure, expressed as a percentage. The result depends on whether the calculation uses paid or incurred claims and which premium basis applies.

01 / The meaning

What it means.

A basic incurred-claims calculation divides incurred claims by earned premium for the same period. Incurred claims can include amounts already paid and estimates for unresolved claims. A business’s own claims experience report may use another convention, so confirm the method before comparing figures. Gross and net measures also differ in how reinsurance is treated.

Loss ratio is not the same as an insurer’s overall profit margin. Administration, distribution, investment results and other items sit outside a simple claims comparison. For a business owner, the figure can help explain renewal discussions, but a single large loss or immature claim estimate can distort a short period. It does not mechanically determine the next premium.

02 / Put it in context

A practical example.

Hypothetical example

Hypothetical example: A report uses $60,000 of incurred claims and $100,000 of earned premium, producing a 60% loss ratio. A large unresolved claim is later reassessed, changing the ratio even though no new incident occurs. The example illustrates calculation, not a target or price forecast.

This example illustrates the term. It does not predict a claim outcome.
