What the result means
The result summarizes the modeled deductible decision for usage based insurance. It is sensitive to the accuracy of the loss, premium, probability, and cost-sharing inputs.
Insurance terms, eligibility, reimbursement, exclusions, and prices vary by insurer and jurisdiction. This estimate is educational and not financial, legal, or insurance advice.
