Understanding Claim Frequency Rate
How we calculate. Frequency = claims ÷ earned exposure units × 100 (as a percent of exposures). The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.
Real-world scenario: A typical Claim Frequency Rate case uses claims 450 and earned exposures 12000. Enter the same figures below to reproduce the worked path.
What is Claim Frequency Rate?
A frequency KPI separate from severity (dollars per claim). Keep the exposure unit definition identical to your actuarial report.
- Same exposure unit as pricing
- Earned exposures preferred
- Pairs with average severity
The Formula
Worked Example
Common Use Cases
- Actuarial triage: frequency vs severity
- Safety programs: claim incidence
- Portfolio health: exposure-normalized claims
Pro Tips
- Don’t mix policy-years and car-years
- State accident vs report year
- Use claims-per-thousand for sparse books
Limitations: Claim Frequency Rate results are educational insurance and agency planning aids—not underwriting, actuarial, claims, or financial advice. Confirm statutory definitions with your carrier, regulator, and finance teams.
FAQ
Percent or per-100?
This form returns claims ÷ exposures × 100. For per-1,000 exposures use the claims-per-thousand tool.
What if earned exposures is 0?
Frequency is undefined—enter positive earned exposures.
