Depreciation Calculator for Vehicle Insurance: Complete Guide
Following a car or bike accident, policyholders take their vehicle to an authorized garage expecting full reimbursement of parts replacement expenses. However, when the final claim settlement advice arrives from the surveyor, a significant portion of the parts cost is deducted as statutory depreciation.
Under the official Indian Motor Tariff guidelines formulated by the Insurance Regulatory and Development Authority of India (IRDAI), insurance companies cannot pay 100% replacement cost for age-affected or wear-and-tear vehicle components under standard motor policies. Our free online Depreciation Calculator for Vehicle Insurance calculates exact material-wise depreciation deductions for plastic, rubber, metal, glass, and fiberglass parts, and compares your out-of-pocket expenses with and without a Zero Depreciation (Zero Dep) add-on cover.
