Claim Frequency Rate

A frequency KPI separate from severity (dollars per claim). Keep the exposure unit definition identical to your actuarial report.

Frequency = claims ÷ earned exposure units × 100 (as a percent of exposures).

Tip: Keep “Claims” and “Earned Exposures” on the same basis (period, units, and population) before calculating Claim Frequency Rate.

Claim frequency rate is claims count relative to earned exposures (cars, policies, or other exposure units).

Enter claim count and earned exposures for the same period.

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

Claim Frequency Rate
Frequency % = (Claims ÷ Earned exposures) × 100

Worked Example

Scenario: 450 claims; 12,000 earned exposures.
Step 1: 450 ÷ 12000 = 0.0375
Step 2: × 100 = 3.75%
Answer: Claim frequency is 3.75%.

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.
