Methodology

Formula

interior_gap    = max(0, repair - walls_in_limit)
assessment_gap  = max(0, assessment_share - loss_assessment_limit)
deductible_pass = master_deductible if passed to the owner, else 0
sewer_gap       = repair if sewer backup is uncovered (then interior_gap = 0)
out_of_pocket   = interior_gap + assessment_gap + deductible_pass + sewer_gap

The result is shown as a range of ±15% around out_of_pocket.

Assumptions

• All numbers are entered by you; the calculator fills in nothing on its own.
• Whether the master deductible is passed to owners depends on state law and your declaration; you set it.
• An uncovered sewer loss counts once: it is not also counted as interior gap.
