Calculate Your Estimated Motor Insurance Premium
Enter the details shown on your registration certificate and renewal quote. The result is an educational estimate, not an insurer quote.
How to Use This Motor Insurance Calculator
- Select comprehensive, third-party-only or standalone own-damage cover.
- Choose renewal or new registration. A new private car uses a three-year third-party premium. A new two-wheeler uses a five-year third-party premium.
- Select the vehicle and power type. Enter engine capacity in cc for an internal-combustion or hybrid vehicle, or motor power in kW for an electric vehicle.
- For cover that includes own damage, enter the proposed IDV and an indicative OD rate. Use the OD rate from an insurer quote when available.
- Select your valid NCB. Enter quoted add-ons and owner-driver personal-accident premium before GST.
- Choose Calculate Premium. Review each component instead of comparing only the final amount.
For the best comparison, run the calculator once for each insurer using the same IDV, cover type, deductibles and add-ons. A cheaper quote with a lower IDV or fewer add-ons is not a like-for-like saving.
Motor Insurance Premium Formula
A comprehensive premium has four main inputs. The insurer prices own damage, the government-notified table supplies the third-party base premium, optional covers add their quoted cost, and GST applies to the taxable premium.
Net OD = Basic OD − NCB saving
Estimated payable premium = (Net OD + TP base premium + add-ons + PA premium) × 1.18
Worked Example
Assume you renew a 1,200 cc private car. Its IDV is ₹8,00,000, the indicative OD rate is 3%, and your NCB is 20%. You have entered no add-on or separate PA premium.
- Basic OD: ₹8,00,000 × 3% = ₹24,000
- NCB saving: ₹24,000 × 20% = ₹4,800
- OD after NCB: ₹24,000 − ₹4,800 = ₹19,200
- One-year TP base premium for a car above 1,000 cc and up to 1,500 cc: ₹3,416
- Premium before GST: ₹19,200 + ₹3,416 = ₹22,616
- GST at 18%: ₹4,071 after rounding
- Estimated amount payable: ₹26,687
The final insurer quote may differ because the OD rate is not a universal tariff. Geography, vehicle model, age, repair costs, claim history, voluntary deductible, anti-theft devices, distribution discounts and insurer underwriting affect it.
What Each Premium Component Means
Third-Party Cover
Third-party motor insurance covers the insured vehicle owner's legal liability for third-party death, injury and property damage, subject to law and policy terms. It does not pay for damage to your own car or bike. A valid third-party policy is mandatory for a vehicle used on a public road in India.
Own-Damage Cover
Own-damage cover protects the insured vehicle against covered events such as accident, theft, fire and specified natural or man-made risks. Insurers price this part. The calculator therefore keeps the OD rate visible and editable instead of presenting one hidden rate as an official tariff.
Insured Declared Value
IDV represents the vehicle's insured value for total-loss and theft settlement, subject to the policy. It is not the same as the original invoice price. A lower IDV often reduces the premium, but it also lowers the maximum basis for a total-loss settlement. Compare quotes at a similar IDV.
No Claim Bonus
NCB is a discount on the own-damage premium for claim-free experience. The standard progression is 20%, 25%, 35%, 45% and 50%. It belongs to the policyholder, not the vehicle, and can usually move to a replacement vehicle with valid proof. It does not reduce third-party premium or add-on prices.
Add-ons and Personal Accident Cover
Zero-depreciation, engine protection, return-to-invoice, roadside assistance, consumables and NCB protection are common add-ons. Their prices and conditions vary. Owner-driver personal-accident cover is a separate line in many quotes. Enter the quoted pre-tax amounts so the calculation stays traceable.
Current Private Vehicle Third-Party Base Premiums
The following tables reproduce the private car and private two-wheeler base-premium values used by the calculator. The one-year column applies to renewal. The new-vehicle column is a single premium for three years on a private car and five years on a private two-wheeler. GST is extra.
Petrol, Diesel and CNG Private Vehicles
| Vehicle | Capacity | One-year TP | New-vehicle TP |
|---|---|---|---|
| Private car | Up to 1,000 cc | ₹2,094 | ₹6,521 for 3 years |
| Private car | Above 1,000 to 1,500 cc | ₹3,416 | ₹10,640 for 3 years |
| Private car | Above 1,500 cc | ₹7,897 | ₹24,596 for 3 years |
| Two-wheeler | Up to 75 cc | ₹538 | ₹2,901 for 5 years |
| Two-wheeler | Above 75 to 150 cc | ₹714 | ₹3,851 for 5 years |
| Two-wheeler | Above 150 to 350 cc | ₹1,366 | ₹7,365 for 5 years |
| Two-wheeler | Above 350 cc | ₹2,804 | ₹15,117 for 5 years |
Private Electric Vehicles
| Vehicle | Motor power | One-year TP | New-vehicle TP |
|---|---|---|---|
| Electric private car | Up to 30 kW | ₹1,780 | ₹5,543 for 3 years |
| Electric private car | Above 30 to 65 kW | ₹2,904 | ₹9,044 for 3 years |
| Electric private car | Above 65 kW | ₹6,712 | ₹20,907 for 3 years |
| Electric two-wheeler | Up to 3 kW | ₹457 | ₹2,466 for 5 years |
| Electric two-wheeler | Above 3 to 7 kW | ₹607 | ₹3,273 for 5 years |
| Electric two-wheeler | Above 7 to 16 kW | ₹1,161 | ₹6,260 for 5 years |
| Electric two-wheeler | Above 16 kW | ₹2,383 | ₹12,849 for 5 years |
Hybrid electric vehicles receive a 7.5% concession on the applicable motor TP base premium. The notified electric-vehicle tables reflect roughly a 15% concession. A private car officially registered as a vintage motor vehicle receives a 50% concession. This calculator rounds discounted TP values to the nearest rupee.
Comprehensive vs Third-Party vs Own-Damage Cover
| Cover | Third-party liability | Damage to insured vehicle | NCB applies | Typical use |
|---|---|---|---|---|
| Comprehensive | Included | Included for covered events | Yes, on OD only | Broad protection in one policy |
| Third-party only | Included | Not included | No | Minimum legal cover |
| Standalone own damage | Not included | Included for covered events | Yes | Used with a separate valid TP policy |
Standalone OD cover does not replace third-party insurance. It is useful when a new vehicle already has a multi-year TP policy but its one-year OD cover needs renewal. Check both policy periods and insurer details before buying.
IDV and Vehicle Age
Traditional motor policy wording uses a depreciation schedule when fixing IDV for vehicles up to five years old. The commonly shown schedule is 5% for a vehicle up to six months old, 15% above six months to one year, 20% above one to two years, 30% above two to three years, 40% above three to four years, and 50% above four to five years.
For a vehicle older than five years or a discontinued model, the insurer and insured agree on the IDV based on the vehicle and market information. Current products may offer an IDV range or different valuation features. Use the IDV printed in the actual quote rather than deriving it from age alone.
A constructive total loss is generally considered when retrieval and repair cost exceeds 75% of IDV, subject to policy terms. This makes IDV material even when two quotes differ by only a small premium amount.
How to Compare Motor Insurance Quotes
- Hold IDV constant. A lower IDV can make one quote look cheaper.
- Compare the same cover type, add-ons and deductible.
- Verify your NCB. An incorrect declaration can create problems during a claim.
- Check cashless garages near your home and regular travel routes.
- Read exclusions, depreciation rules, sub-limits and claim conditions.
- Check whether consumables, tyres, batteries, keys and engine damage are covered.
- Review insurer service and claim support, not price alone.
- Confirm the policy start date so third-party cover never lapses.
Ways to Reduce Premium Carefully
You can compare insurers, remove add-ons you do not need, select an affordable voluntary deductible, retain valid NCB and use an approved anti-theft device where a discount applies. Avoid reducing IDV solely to reach a target premium. The saving is small compared with the possible reduction in a theft or total-loss settlement.
Common Calculation Mistakes
- Applying NCB to the full premium. It applies to the OD portion, not TP or GST.
- Using cc for an electric vehicle. EV third-party bands use motor power in kW.
- Treating a new-vehicle bundled premium as one-year cover. Only OD is normally modelled for one year, while TP runs for three or five years.
- Forgetting GST. Motor insurance remains taxable at 18% for the private vehicle policies covered by this calculator.
- Adding an owner-driver PA premium without checking whether a valid qualifying cover already exists.
- Comparing a third-party-only quote with a comprehensive quote.
- Assuming the calculator guarantees acceptance, coverage or a claim payment.

Frequently Asked Questions
How is a motor insurance premium calculated in India?
A comprehensive estimate combines own-damage premium after NCB, the applicable third-party base premium, add-ons, owner-driver PA premium and GST. Insurers set the OD rate and other discounts, while notified tables determine the private-vehicle TP base premium.
What is the third-party premium for a 1,200 cc private car?
The current one-year base premium is ₹3,416 before GST because the engine is above 1,000 cc and up to 1,500 cc. For a new private car, the three-year single TP base premium is ₹10,640 before GST.
Does NCB reduce the entire car insurance premium?
No. NCB reduces the basic own-damage premium. It does not reduce third-party premium, add-on premium, personal-accident premium or GST.
What NCB percentage should I select?
Select the percentage supported by your renewal notice or NCB certificate. The standard claim-free progression is 20%, 25%, 35%, 45% and 50%. Do not select a higher percentage only to lower the estimate.
Is GST charged on motor insurance in 2026?
Yes. This calculator applies 18% GST to private motor insurance premium components. The 2025 exemption for individual life and health insurance did not extend to motor insurance.
Why does a new car or bike show a higher third-party premium?
A new private car requires a three-year TP term, while a new private two-wheeler requires a five-year TP term. The higher amount is a multi-year single premium, not a one-year charge.
How should I choose the IDV?
Use a reasonable value within the insurer's permitted range and compare quotes at the same IDV. A lower IDV reduces premium but also reduces the value used for theft or total-loss settlement.
Does this calculator work for electric vehicles?
Yes. Select battery electric and enter motor power in kW. The tool uses the notified EV TP bands for private cars and two-wheelers. The OD estimate still depends on the IDV and editable OD rate.
Is the calculated premium a guaranteed quote?
No. It is an educational estimate. The final premium and coverage depend on the insurer's rates, underwriting, vehicle inspection, discounts, location, policy wording, taxes and information supplied by you.
Sources and Methodology
The calculator separates notified TP values from insurer-priced OD estimates. It uses the statutory private-vehicle tables, applies the published hybrid, EV and vintage concessions, and keeps every non-statutory cost editable.
