Real-world scenario: A typical Loss Adjustment Expense Ratio case uses loss adjustment expenses 780000 and incurred losses 6500000. Enter the same figures below to reproduce the worked path.
What is Loss Adjustment Expense Ratio?
A claims-cost KPI distinct from the underwriting expense ratio (which usually uses premium). Some shops also report LAE ÷ earned premium—label that variant separately.
- LAE over losses in this tool
- Same incurred definition as loss ratio
- Separate ALAE vs ULAE in analysis
The Formula
Worked Example
Common Use Cases
- Claims finance: adjustment cost load
- TPA oversight: expense efficiency

Pro Tips
- Watch defense-cost heavy LOBs
- Don’t mix premium-based expense ratio
- Normalize catastrophe spikes
Limitations: Loss Adjustment Expense Ratio 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
LAE ÷ premium instead?
That is a different metric. This calculator uses LAE ÷ incurred losses; use expense ratio for premium-based expense loads.
What if incurred losses is 0?
LAE ratio is undefined—enter positive incurred losses.
