Car Insurance Calculator Estimates IDV and Premiums Before Purchase
A car insurance calculator gives you an estimate of what insurance may cost before you buy it.
You enter details about your car, such as its age, model and fuel type.
The tool can estimate the car’s insured value after depreciation.
It also estimates different parts of the insurance cost.
Third-party premiums are set using rules from IRDAI, while own-damage costs depend on the car’s value, discounts and add-ons.
Comprehensive insurance combines third-party and own-damage cover.
Comparing estimates can help people choose coverage that suits their needs and budget.
The article says TATA AIG offers a calculator for this purpose.
An online car insurance calculator estimates premiums using details such as vehicle age, make, model and fuel type.
The calculator can estimate a car’s Insured Declared Value, or IDV, based on its value after depreciation.
Third-party premium rates are set by IRDAI and depend on fuel type and engine capacity; rates may be revised periodically.
Own-damage premiums depend on IDV, the insurer’s tariff rate, discounts such as No Claim Bonus and selected add-ons.
Comprehensive premium combines own-damage and third-party premiums, and calculators can help users compare coverage options.
