Calculated outcomes
- Insured Proportion Percent
- 75%
Assumptions and estimates
- Illustrative average clause: scale covered loss by declared sum/rebuild value, cap at sum insured, then deduct the excess. Use rebuild/replacement cost, not market value. Policy wording, limits, agreed values, tolerances and excess ordering can differ; this is not an insurer’s claim determination.
- Method: Scale loss by insured sum / rebuild value if an average clause applies, cap at insured sum, then deduct excess.
- Editable inputs are planning assumptions; check the method and result notes for scope.
