Why these tools exist
A deductible, depreciation adjustment or weekly benefit cap can make a result hard to interpret. These tools separate those inputs and show the arithmetic. They cannot read your policy, decide coverage, predict a renewal premium or replace professional advice.
So the rule here is simple. The aim is to make every number a tool produces reproducible by hand, the working is shown, and the assumptions link out to the regulator or agency they came from — state insurance departments, the CFPB, the Insurance Information Institute. Where a figure comes from an industry estimate rather than a regulator, the page says so plainly and lets you override it. Where a question genuinely cannot be answered by a calculator, the page says that too.
