Why use this commercial property insurance calculator & coverage gap?
Estimate commercial property insurance gap with editable commercial assumptions and a transparent browser-based calculation. The model compares modeled exposure with available limit and retention to highlight a potential coverage or capacity gap.
Inputs used in this model
- Modeled exposure: default example 1,000,000
- Coverage / contractual limit: default example 750,000
- Retention / deductible: default example 25,000
How to interpret the result
A modeled gap identifies where entered capacity is below entered exposure. Policy wording, sublimits, exclusions and attachment points still need separate review. Change the most uncertain inputs and compare multiple scenarios rather than relying on a single default case.
Example
Replace the sample figures with values from your own quote, contract, policy, cloud bill, payroll report or operating plan. Compare a base case with at least one higher-cost or lower-volume scenario.
