Car Insurance Premium Calculator

Under the Motor Vehicles Act 1988, motor insurance is mandatory for every vehicle plying on Indian roads. A comprehensive car insurance policy combines mandatory third-party liability coverage with own-damage protection against accidents, theft, fire, and natural calamities.

The FinToolkit Car Insurance Premium Estimator models the standard tariff components: Insured Declared Value (IDV), engine cubic capacity (cc), vehicle age, No Claim Bonus (NCB) discount, and add-on covers to estimate your total renewal premium including 18% GST.

How car insurance premium is broken down

A comprehensive car insurance policy consists of three distinct components:

1. Third-Party (TP) Liability Premium: Fixed statutory tariff mandated by the Insurance Regulatory and Development Authority of India (IRDAI) based strictly on engine cubic capacity (under 1,000cc, 1,000cc to 1,500cc, or above 1,500cc).
2. Own Damage (OD) Premium: Calculated as a percentage of your car's Insured Declared Value (IDV) based on vehicle age, make, and geographical zone.
3. Add-On Covers: Optional endorsements (such as Zero Depreciation, Engine Protect, Roadside Assistance, and Return to Invoice) that enhance claim settlements.

Worked premium calculation example

Consider a 3-year-old mid-sized car (1,000cc to 1,500cc engine) with an Insured Declared Value (IDV) of ₹6,00,000, holding an accrued 20% No Claim Bonus, adding ₹3,000 worth of optional endorsements (Zero Depreciation).

Understanding Insured Declared Value (IDV)

IDV is the maximum sum assured paid by the insurer in case of total loss or theft. It represents the manufacturer's listed selling price adjusted for standard statutory depreciation:

• Up to 6 months: 5% depreciation
• 6 months to 1 year: 15% depreciation
• 1 to 2 years: 20% depreciation
• 2 to 3 years: 30% depreciation
• 3 to 4 years: 40% depreciation
• 4 to 5 years: 50% depreciation

Caution: Never artificially lower your IDV just to get a cheaper premium. If your car is stolen or totaled, the insurer will pay only the declared IDV.

Frequently asked questions

What is the No Claim Bonus (NCB) slab structure?

NCB is a reward for claim-free policy years that discounts your Own Damage premium: Year 1 = 20%, Year 2 = 25%, Year 3 = 35%, Year 4 = 45%, and Year 5 = 50% maximum discount. Making even one small claim resets NCB to zero unless you have an NCB Protect add-on.

Is the No Claim Bonus tied to the car or the owner?

NCB belongs to the policyholder, not the car. When you sell an old car and purchase a new one, you can retain your accrued NCB certificate and transfer up to 50% discount to your new vehicle policy.

Is Zero Depreciation cover worth the extra cost?

Yes, especially for cars under 5 years old. Without Zero Dep, standard claims deduct 50% depreciation on rubber/nylon/plastic parts and up to 30% on metal parts, leaving you with substantial out-of-pocket repair costs.
