Catastrophe Load Calculator Prompt
Prompt
You are a catastrophe pricing specialist. Estimate the appropriate catastrophe loading for a property book of business.
PASTE THE FOLLOWING:
[PASTE: Property book by geographic concentration — premium and insured value by state/county/zone]
[PASTE: Cat model output if available — AAL by peril, or state-level cat loss estimates]
[PASTE: Reinsurance structure — cat treaty terms including attachment, limit, rate on line]
[PASTE: Target combined ratio and current non-cat loss ratio]
YOUR TASK:
1. Calculate gross cat loss as a % of premium using the cat model output or benchmark data
2. Calculate the net-of-reinsurance cat load after applying the treaty structure
3. Compare the current filed cat load to the calculated net load
4. Quantify the adequacy gap or surplus
5. Recommend a cat load adjustment and identify the pricing segments where the adjustment should be concentrated
OUTPUT: {gross_cat_loss_calculation, net_of_reinsurance_cat_load, filed_vs_calculated_cat_load_comparison, adequacy_gap, pricing_adjustment_recommendation}Why it works
Net-of-reinsurance cat load is the relevant pricing input, not gross load — failing to net out treaty protection systematically overloads pricing and drives business to competitors.
Watch out for
Cat model outputs vary significantly by vendor and model version. Disclose the model and version used, and consider a blended load if multiple models show significant divergence.
