Coinsurance in Commercial Property

Purpose

Coinsurance ensures that commercial policyholders carry adequate insurance relative to their property value.

Common Coinsurance Percentages

  • 80% (most common)
  • 90%
  • 100%

Coinsurance Formula

Payment=Insurance CarriedInsurance Required×LossDeductible\text{Payment} = \frac{\text{Insurance Carried}}{\text{Insurance Required}} \times \text{Loss} - \text{Deductible}

Insurance Required = Property Value × Coinsurance Percentage

Coinsurance Example

FactorAmount
Building Value$1,000,000
Coinsurance %80%
Insurance Required$800,000
Insurance Carried$600,000
Loss Amount$200,000
Deductible$1,000

Calculation:

  • Did insured meet requirement? $600,000 < $800,000 = NO
  • Ratio: $600,000 ÷ $800,000 = 75%
  • Payment: ($200,000 × 75%) - $1,000 = $149,000
  • Coinsurance penalty: $50,000

Avoiding Coinsurance Penalties

  • Carry at least the required percentage
  • Use Agreed Value endorsement
  • Conduct regular property appraisals
  • Review coverage annually

Exam Tip: Coinsurance penalizes under-insurance. Wisconsin businesses must carry at least 80% (or the stated percentage) of their property value to avoid becoming a co-insurer.
