Car insurance premium in India is not one fixed price: the bill combines mandatory third-party liability cover with an own-damage portion that insurers rate differently. This guide shows how the split works, how IDV and No Claim Bonus affect the renewal quote, and how to compare two offers without treating a lower number as identical cover.
The most important takeaway is simple: compare the premium with the IDV, deductible, exclusions and add-ons printed in the schedule. A cheaper quote can reflect a lower insured value or a higher amount payable by you during a claim.
Key takeaways
- Third-party (TP) cover is the legal minimum; its base premium is linked to the vehicle category and, for private petrol or diesel cars, the engine-capacity slab.
- Own-damage (OD) pricing varies by insurer and reflects the car's IDV, age, model, location, claim history, deductible and selected add-ons.
- NCB reduces the OD premium only. IRDAI consumer guidance describes the benefit as starting at 20% and progressing to a maximum of 50% under current norms.
- The latest published private-car TP reference table lists base premiums of ₹2,094, ₹3,416 and ₹7,897 across three engine-size bands, before other components.
- A 17 Oct 2026 report about risk-based TP pricing describes an industry proposal, not a new rule. The live rate and policy wording still need checking at renewal.
Why this question matters now
The Economic Times reported on 17 Oct 2026 that some motor-insurance industry participants asked the Insurance Regulatory and Development Authority of India (IRDAI) to consider risk-based third-party pricing, along with other changes to motor-insurance arrangements. The report describes feedback to a consultation process; it does not announce a change in what a private-car owner must pay.
That proposal makes the present pricing mechanism worth understanding. It is how to read today's quote, separate regulated liability cover from insurer-rated own-damage cover, and identify the terms that matter when two quotes look different.
For the latest context, read our report on the risk-based third-party pricing proposal, then use this guide as the longer-term renewal reference.
The premium has two main parts
| Cover part | What it protects | How the price is formed | What it does not pay for |
|---|---|---|---|
| Third-party liability | Your legal liability for injury, death or property damage caused to another party | Base rates are notified for vehicle categories; private-car petrol and diesel rates use engine capacity | Damage to your own car |
| Own damage | Loss or damage to the insured car, subject to policy terms | Insurer-rated using IDV, vehicle details, claims, location, deductible and add-ons | Items excluded by the wording, such as an unlisted or excluded loss |
| Package or bundled policy | Third-party liability plus own-damage cover in one policy structure | The TP portion and OD portion are combined with applicable options and charges | Anything outside the selected cover, limits or exclusions |
IRDAI's policyholder guidance says third-party insurance is mandatory for vehicles used on public roads. It also separates the two pricing ideas: TP premiums are laid down by the regulator, while own-damage rates differ between insurers for similar cover. The final payable amount can therefore differ even when the TP base is the same.
Third-party premium: read the engine-capacity slab carefully
As of 18 Oct 2026, the latest published private-car reference table used in this guide comes from the Motor Vehicles (Third Party Insurance Base Premium and Liability) Rules, 2022, and is also reproduced in a 2 Sep 2026 explainer by Generali Central. These are base annual premiums for private cars before other components; they are not a promise that every renewal invoice will have the same total.
| Private-car engine capacity | Base TP premium | Reference status |
|---|---|---|
| Not exceeding 1,000 cc | ₹2,094 | MoRTH Rules 2022; latest reference checked Oct 2026 |
| Above 1,000 cc and not exceeding 1,500 cc | ₹3,416 | MoRTH Rules 2022; latest reference checked Oct 2026 |
| Above 1,500 cc | ₹7,897 | MoRTH Rules 2022; latest reference checked Oct 2026 |
- The slab is based on engine capacity, not the car's ex-showroom price.
- Electric cars follow a separate motor-output or vehicle-category schedule; the petrol/diesel engine-cc table should not be applied to an EV.
- These figures are the base TP reference, not the complete cost of a package policy. Add-ons, own-damage cover and other applicable charges can change the final payable amount.
- Since the October 2026 industry discussion is a proposal, not a notification, the current insurer quote and the applicable regulatory schedule remain the final checks.
Third-party cover protects other people and property, not the repair bill for your own car. As of October 2026, IRDAI consumer guidance describes unlimited liability for third-party death or injury and a ₹7.5 lakh limit for third-party property damage under the stated cover.
Own-damage premium: the factors that move your quote
1. IDV sets the ceiling for a total-loss claim
Insured Declared Value, or IDV, is the sum insured for the vehicle under own-damage cover. IRDAI says it should reflect the car's current market value. For a total loss, theft or constructive total loss, the IDV is central to the amount considered under the policy terms; it is not automatically the same as the original on-road price.
At renewal, compare the IDV shown by each insurer with the car's real market position. A lower IDV can reduce the own-damage price, but it also reduces the stated ceiling for a total-loss or theft settlement. Our IDV and depreciation guide explains this part of the policy in more detail.
2. NCB reduces the own-damage portion
No Claim Bonus is a discount for a claim-free record. As of October 2026, IRDAI's current consumer guidance says it applies to the own-damage premium, not the TP premium, and ranges from 20% to a maximum of 50%. The standard policy wording hosted in IRDAI's archive lays out the familiar progression of 20%, 25%, 35%, 45% and 50% after successive claim-free periods.
NCB belongs to the insured person rather than permanently to the vehicle. A change of car or insurer therefore requires the NCB evidence and transfer conditions to be checked. A break in cover can also affect the benefit: IRDAI says a lapsed policy may require inspection, and the accrued NCB can be lost when a comprehensive policy remains expired beyond the stated period.
3. Vehicle, driver and location details affect risk
The proposal and policy schedule use details such as the registration information, make and model, engine capacity, seating capacity, vehicle age, location, driver details and previous claims. These details must match the RC and the actual use of the car. A quote is not comparable if one form has an incorrect variant, a different registration location or an incomplete claims history.
4. Deductible changes the claim share
A deductible, also called an excess, is the amount that remains payable by the insured before the insurer pays the eligible balance. A higher deductible can make a quote look lower while leaving more of a repair bill with the owner. Compare the compulsory deductible, any voluntary deductible and the wording for parts, labour and sub-limits.
5. Add-ons and exclusions change what the premium buys
Zero-depreciation, engine protection, roadside assistance, return-to-invoice and consumables cover can change both price and claim conditions. Inspect eligibility, limits and exclusions. Our zero-depreciation versus comprehensive guide covers why the add-on label must be read with the base policy.
Third-party, package or standalone OD: a practical comparison
| Option | Own-car damage covered? | Useful comparison points |
|---|---|---|
| Third-party only | No | Mandatory liability protection; compare the applicable TP rate and policy service terms |
| Package or comprehensive | Yes, subject to IDV, deductibles and exclusions | Compare the TP component, OD price, IDV, NCB and add-ons together |
| Standalone OD plus TP | Yes, through a separate OD policy | Check that the two policies overlap correctly in dates, vehicle details and claims process |
There is no single universally suitable format. The right comparison depends on the car's value, existing TP term, desired own-damage protection and the conditions printed by the insurer. Avoid judging cover by the word “comprehensive” alone; the schedule and exclusions decide what is actually included.
Worked rupee example: separating TP, OD and NCB
Consider a hypothetical renewal for a 1,200 cc private petrol car. The published reference slab above gives a base TP premium of ₹3,416. Now assume, only for illustration, that the insurer's own-damage portion before add-ons and other applicable charges is ₹12,000, and the owner has one claim-free year eligible for a 20% NCB.
- Illustrative OD discount: ₹12,000 × 20% = ₹2,400.
- Illustrative OD amount after NCB: ₹12,000 − ₹2,400 = ₹9,600.
- Illustrative TP plus OD before other components: ₹3,416 + ₹9,600 = ₹13,016.
This is arithmetic, not a market quote. The assumed ₹12,000 OD amount, the car's 1,200 cc example and the final ₹13,016 subtotal do not predict what any insurer will charge. A real quote can change with IDV, location, claim history, deductible, add-ons, taxes and policy terms. The example's useful lesson is that NCB applies to the OD line, not to the TP line.
A second illustration shows the IDV trade-off. If a notional listed value of ₹8,00,000 is reduced by an assumed 20% for demonstration, the result is ₹6,40,000. That is not a prescribed calculation for a specific car; it simply shows why a lower insured value can reduce the apparent premium while also lowering the total-loss reference amount.
What to check before paying a renewal quote
- Match the registration number, make, model, variant, engine or motor details and registration location with the RC.
- Record the policy expiry date and ask whether a break in cover will require inspection or affect NCB.
- Separate the TP line from the OD line and check whether the TP term is annual or part of a longer bundled policy.
- Compare IDV across quotes and note any large difference before comparing the premium.
- Confirm that the NCB percentage and supporting history have carried forward correctly.
- List every add-on, its limit, eligibility, claim condition and exclusion; remove nothing silently from a comparison.
- Compare compulsory and voluntary deductibles, parts depreciation, sub-limits and cashless or repair conditions.
- Save the policy schedule, receipt, insurer contact and claim instructions. For a lapsed policy, use the checks in our expired-policy renewal and NCB guide.
- Keep the current RC, PUC and previous policy details available. For a claim, use the document sequence in our car insurance claim process guide.
Frequently asked questions
Is the third-party premium identical with every insurer?
The regulated base TP rate for the same vehicle category is intended to be uniform, but the total invoice can differ because of own-damage cover, add-ons and other applicable components. Compare the base TP line and the rest of the schedule separately.
Why do two car insurance quotes show different prices?
Own-damage pricing can differ because insurers rate the car, location, claims, IDV, deductible and selected add-ons differently. A quote with a lower IDV or a higher deductible is not an apples-to-apples comparison with a quote offering a higher IDV or lower claim share.
Does NCB reduce the whole car insurance premium?
No. IRDAI's guidance places NCB on the own-damage premium, not the third-party premium. The rupee reduction therefore depends on the OD portion and the applicable NCB percentage.
Does a lower premium mean the policy is better?
Not by itself. Read the IDV, deductibles, exclusions, add-on limits, claim conditions and TP/OD split before deciding whether two quotes provide comparable protection.
