TP Insurance Costs ₹2,094. Comprehensive Costs ₹8,000-35,000. Here Is What You Are Actually Paying For.
Third-party car insurance is legally mandatory. It costs ₹2,094-7,897/year — fixed by IRDAI, identical across every insurer in India. It covers only the other person’s damages. Your car gets nothing.
Comprehensive insurance adds own-damage (OD) cover on top. A hatchback pays ₹5,000-8,000 extra. An SUV pays ₹15,000-27,000 extra. The exact amount depends on your car’s IDV, age, city, and claim history.
The ₹45,000 question nobody asks until it is too late: On a standard comprehensive policy without zero-depreciation, a ₹1.80 lakh repair bill means ₹45,000 from your pocket in part depreciation deductions. The insurer pays ₹1.35 lakh. You assumed they would pay everything.

IRDAI-Fixed Third-Party Premium Rates (Current)
These rates are set by IRDAI. Every insurer charges exactly the same. No discounts, no negotiation.
Petrol/Diesel/CNG Cars
| Engine Capacity | Annual TP Premium |
|---|---|
| Up to 1,000cc | ₹2,094 |
| 1,001-1,500cc | ₹3,416 |
| Above 1,500cc | ₹7,897 |
Electric Vehicles (15% IRDAI Discount)
| EV Power Rating | Annual TP Premium | Example Models |
|---|---|---|
| Under 30 kW | ₹1,780 | MG Comet |
| 30-65 kW | ₹2,904 | Tata Nexon EV, Punch.ev |
| Above 65 kW | ₹6,712 | BYD Atto 3, Kia EV6 |
These rates have remained unchanged since 2019-2021. An 18-25% increase is proposed for FY 2025-26 (pending MoRTH notification).
What TP covers: Damage to the other person’s vehicle, property, or body. Death or permanent disability of third parties. Legal liability arising from accidents caused by your vehicle.
What TP does NOT cover: Any damage to your own car. Theft of your vehicle. Fire, flood, or natural disaster damage. Personal accident cover for you (separate add-on since 2019).
Own-Damage Premium: The Real Math
OD premium is where the price variation happens. Two identical cars can have dramatically different OD premiums based on five variables.
The Formula
OD Premium = (IDV x Base Rate) - NCB Discount + Add-ons + GST
IDV Depreciation Schedule (IRDAI-Mandated)
IDV (Insured Declared Value) = what the insurer pays on total loss or theft. It drops every year:
| Vehicle Age | Depreciation on IDV | IDV on ₹10 Lakh Car |
|---|---|---|
| New (under 6 months) | 5% | ₹9,50,000 |
| 6 months - 1 year | 15% | ₹8,50,000 |
| 1-2 years | 20% | ₹8,00,000 |
| 2-3 years | 30% | ₹7,00,000 |
| 3-4 years | 40% | ₹6,00,000 |
| 4-5 years | 50% | ₹5,00,000 |
| Over 5 years | Negotiated between insurer and owner | ₹2,00,000-3,50,000 |
After 5 years, IDV is no longer formula-based. Insurers assess the car’s market value — and consistently lowball it. A well-maintained 7-year-old Honda City might sell for ₹4 lakh in the market but get ₹2.5 lakh IDV. Always negotiate IDV upward.
OD Base Rate
Typically 2.5-3.5% of IDV for petrol vehicles. Diesel vehicles are slightly higher. CNG vehicles carry a 5% premium increase.
Comprehensive Premium by Car Segment (Illustrative)
| Car | Ex-Showroom | IDV (2 Years Old) | TP Premium | OD Premium | Total (Pre-GST) |
|---|---|---|---|---|---|
| Maruti Alto (796cc) | ₹3.5L | ₹2.8L | ₹2,094 | ₹4,200 | ₹6,294 |
| Maruti Swift (1,197cc) | ₹6.5L | ₹5.2L | ₹3,416 | ₹7,800 | ₹11,216 |
| Honda City (1,498cc) | ₹12L | ₹9.6L | ₹3,416 | ₹14,400 | ₹17,816 |
| Hyundai Creta (1,497cc) | ₹15L | ₹12L | ₹3,416 | ₹18,000 | ₹21,416 |
| Toyota Fortuner (2,755cc) | ₹35L | ₹28L | ₹7,897 | ₹42,000 | ₹49,897 |
Assumes 0% NCB, no add-ons, Zone A (metro). Add 18% GST to total.
NCB Discount: How ₹18,000 Becomes ₹9,000
No Claim Bonus applies only to the OD component. TP premium is unaffected.
| Consecutive Claim-Free Years | NCB Discount on OD |
|---|---|
| 1 year | 20% |
| 2 years | 25% |
| 3 years | 35% |
| 4 years | 45% |
| 5+ years | 50% (maximum) |
Real Savings Example
A Hyundai Creta with ₹18,000 OD premium and 5-year NCB:
- OD after NCB: ₹18,000 x 50% = ₹9,000
- TP: ₹3,416 (unchanged)
- Total: ₹12,416 vs ₹21,416 without NCB
Annual savings: ₹9,000. Over the next 5 years (assuming no claims): ₹45,000 saved.
Five NCB Rules That Catch People Off Guard
-
One claim resets everything. Five years of claim-free driving earns 50% NCB. One ₹8,000 windshield claim resets it to 0%. Next year’s premium jumps ₹9,000. The windshield claim cost you ₹1,000 in savings.
-
90-day lapse = permanent loss. If you miss your renewal window by more than 90 days, all accumulated NCB is gone. No exceptions, no appeals.
-
NCB follows the person, not the car. When you sell your car, NCB stays with you. The buyer starts at 0%. When you buy a new car, carry your NCB certificate to the new insurer.
-
Verification trap. New insurer verifies NCB with old insurer. If records mismatch (common when switching between PSU and private insurers), you pay the premium difference retroactively.
-
NCB Protection add-on exists. Costs 5-10% of OD premium. Allows 1 claim per year without losing NCB. Worth it if OD premium is above ₹12,000 and you have 4+ years NCB accumulated.
The Depreciation Trap: What You Actually Get Paid During a Claim
This is the single biggest surprise at claim time. Standard comprehensive policies deduct part depreciation on every replacement.
Part-Wise Depreciation (Applied on Every Claim)
| Part Type | Depreciation Deducted | You Pay From Pocket |
|---|---|---|
| Rubber, nylon, plastic parts | 50% | Half the cost |
| Tyres, tubes, batteries | 50% | Half the cost |
| Fibre/fiberglass components | 30% | 30% of cost |
| Metal body parts | 10-15% | 10-15% of cost |
| Glass parts | 0% | Nothing (fully covered) |
Real Claim Scenario: Rear-End Collision on a 3-Year-Old Creta
| Part Replaced | Cost | Depreciation | You Pay |
|---|---|---|---|
| Rear bumper (plastic) | ₹15,000 | 50% | ₹7,500 |
| Tail lights (plastic/glass) | ₹12,000 | 50% on plastic | ₹4,000 |
| Dicky panel (metal) | ₹25,000 | 15% | ₹3,750 |
| Boot lock assembly | ₹5,000 | 50% (plastic) | ₹2,500 |
| Paint + labor | ₹18,000 | 0% | ₹0 |
| Total repair | ₹75,000 | ||
| Compulsory deductible | ₹1,000 | ||
| Total you pay | ₹18,750 | ||
| Insurer pays | ₹56,250 |
Without being told, you assumed ₹75,000 claim = ₹75,000 payout. Reality: ₹56,250 payout, ₹18,750 from your pocket. That is a 25% gap.
Zero Depreciation Add-On: Cost vs Savings by Car Segment
Zero-dep eliminates part depreciation deductions. You pay only the compulsory deductible (₹1,000-2,000 per claim).
| Car Segment | Standard OD Premium | Zero-Dep Add-On Cost | Total with Zero-Dep |
|---|---|---|---|
| Maruti Swift (Hatchback) | ₹5,200 | +₹900 | ₹6,100 |
| Honda City (Sedan) | ₹7,800 | +₹1,400 | ₹9,200 |
| Maruti Brezza (Compact SUV) | ₹9,100 | +₹1,800 | ₹10,900 |
| Hyundai Creta (Mid SUV) | ₹11,500 | +₹2,400 | ₹13,900 |
| Toyota Fortuner (Premium SUV) | ₹22,000 | +₹5,000 | ₹27,000 |
The Math That Settles the Debate
Using the Creta rear-end collision example above:
- Without zero-dep: You pay ₹18,750 from pocket
- With zero-dep: You pay ₹2,000 (compulsory deductible only)
- Savings on one claim: ₹16,750
- Annual zero-dep cost: ₹2,400
One claim saves 7x the annual add-on cost. Zero-dep pays for itself on the first claim for any car under 5 years.
When Zero-Dep Is NOT Worth It
- Car older than 5 years (IDV already down 50%, parts cheaper, add-on premium loading jumps to 30%+)
- You have 10+ years driving experience with zero claims history
- Car is rarely driven (under 3,000 km/year)
Add-On Covers: What Each Costs and Whether It Pays
| Add-On | Cost (% of OD Premium) | What It Covers | Worth It? |
|---|---|---|---|
| Zero Depreciation | +20% | Eliminates part depreciation deductions | Yes, for cars under 5 years |
| Engine Protection | +10% | Hydrostatic lock (water entering engine), oil leakage damage | Yes, in flood-prone cities (Mumbai, Chennai, Kolkata) |
| Return to Invoice | +15% | Full invoice price on total loss/theft (not depreciated IDV) | Yes, for new cars under 2 years |
| Consumables Cover | +8% | Nuts, bolts, engine oil, coolant, AC gas, bearings | Yes, adds ₹500-800 but saves ₹3,000-5,000 per claim |
| Roadside Assistance | ₹500 flat | Towing, flat tyre, battery jumpstart, fuel delivery | Optional (most car brands offer 3-5 year free RSA) |
| NCB Protection | +5-10% | Allows 1 claim/year without losing NCB | Yes, if NCB is 35%+ and OD premium exceeds ₹12,000 |
| Personal Accident | ₹750 flat | ₹15 lakh cover for owner-driver death/disability | Mandatory if no standalone PA policy |
| Key Replacement | ₹200-500 | Covers cost of new key + reprogramming | No (modern key replacement costs ₹3,000-8,000 — just pay it) |
| Tyre Protection | ₹500-1,000 | Tyre damage from road hazards | No (tyres are consumables, replacement is predictable) |
Claim Settlement Ratios and Cashless Networks: Insurer Comparison
The Numbers That Matter
| Insurer | Claim Settlement Ratio | Cashless Garages | Average Claim Time |
|---|---|---|---|
| SBI General | 100% | 16,000+ | 7-10 days |
| HDFC ERGO | 99-100% | 8,700+ | 5-7 days |
| ICICI Lombard | 99% | 6,100+ | 7-10 days |
| TATA AIG | 99% | 10,000+ | 7-12 days |
| Royal Sundaram | 98% | 7,600+ | 10-15 days |
| Bajaj Allianz | 91-98% | 7,200+ | 7-10 days |
| Go Digit | 96% | 6,000-9,000+ | 5-7 days |
Why CSR Alone Is Misleading
CSR counts number of claims settled, not amount paid. An insurer settling a ₹500 windshield claim and a ₹5 lakh accident claim counts both as “1 settled claim.” An insurer could have 100% CSR but consistently pay only 70% of claimed amounts through depreciation deductions and surveyor undervaluation.
What to check instead: Ask the insurer’s surveyor valuation track record. Read Google/MouthShut reviews specifically about claim payout amounts, not just claim speed.
Cashless vs Reimbursement: The Real Difference
- Cashless (network garage): Zero upfront payment. Insurer settles directly with the garage. Takes 2-4 hours for approval, repair starts immediately.
- Reimbursement (non-network garage): You pay the full bill upfront, then file for reimbursement. Takes 15-30 days to get money back. Surveyor visits after repair — disputes are common.
Always check: Before buying, verify how many cashless garages are within 10 km of your home and office. A policy with 16,000 garages nationally means nothing if none are near you.
When Third-Party-Only Is Enough (And When It Is Financial Suicide)
TP-Only Makes Sense When:
| Condition | Why |
|---|---|
| Car older than 8-10 years, IDV below ₹1.5-2 lakh | OD premium (₹3,000-5,000) is 2-3% of car value. Self-insuring is cheaper. |
| Emergency fund of ₹3-5 lakh available | You can absorb a total loss without financial stress |
| Car driven under 3,000 km/year | Lower exposure = lower risk |
| Second car used only for short errands | Low-speed city driving, minimal highway exposure |
TP-Only Is Financial Suicide When:
| Condition | Why |
|---|---|
| Car is under 5 years old | A single accident repair costs ₹50,000-2 lakh. OD premium is ₹5,000-15,000. |
| Car is financed (loan/lease) | Lender mandates comprehensive cover. No choice. |
| Car is parked in flood-prone area | Engine hydrostatic lock repair: ₹1.5-4 lakh. Not covered under TP. |
| Car is a daily highway commuter | Higher speed = higher severity. Single highway accident: ₹2-5 lakh repair. |
| You cannot afford to replace the car | If total loss means you lose transportation, you need OD cover. |
The Break-Even Calculation
For any car, calculate: OD premium / IDV x 100 = cost as % of car value
- Below 2%: Comprehensive is clearly worth it
- 2-4%: Marginal — depends on your risk tolerance
- Above 5%: TP-only with self-insurance is more economical
Example: ₹5,000 OD premium on a car with ₹1.5 lakh IDV = 3.3%. Borderline. But ₹12,000 OD premium on a car with ₹8 lakh IDV = 1.5%. No-brainer — buy comprehensive.
Electric Vehicle Insurance: What Changes
EV insurance has three structural differences from petrol/diesel:
1. Higher OD Premiums (20-40% More)
The battery pack is 40-60% of total car value. A minor front-end collision on a Tata Nexon EV that damages the battery module can trigger a ₹7 lakh claim on a ₹15 lakh car. Fewer trained EV mechanics + limited spare parts = higher repair costs and longer timelines.
2. Lower TP Premiums (15% IRDAI Discount)
EVs get a flat 15% reduction on third-party rates. This partially offsets the higher OD cost, but not fully.
3. Essential EV-Specific Add-Ons
| Add-On | Why It Is Non-Negotiable |
|---|---|
| Battery Protection Cover | Covers consequential battery damage from accidents, water ingress, short circuits |
| Charger Coverage | Home wall-box chargers (₹30,000-80,000) are NOT covered by default |
| Zero Depreciation | Without it, battery replacement attracts 50% depreciation — ₹3.5 lakh from your pocket on a ₹7 lakh battery |
Total cost of EV-specific add-ons: approximately ₹5,000/year.
Third-Party Liability: The Unlimited Risk Nobody Thinks About
TP insurance is not optional because TP liability has no upper limit in India.

| 31-35 years | 16 |
| 36-40 years | 15 |
| 41-45 years | 14 |
| 46-50 years | 13 |
| 51-55 years | 11 |
Recent MACT (Motor Accident Claims Tribunal) Awards
| Case | Award Amount | Details |
|---|---|---|
| Thane MACT, 2025 | ₹49.4 lakh | 25-year-old software engineer killed in road accident |
| Thane MACT, 2025 | ₹19.24 lakh | Motorcycle accident fatality |
| Supreme Court, 2024 | ₹35.9 lakh | 8-year-old victim — 9x the High Court award |
| Supreme Court, 2025 | ₹7.14 lakh | Third-party injury claim |
A 30-year-old IT professional earning ₹8 lakh/year with 2 dependents: (₹8,00,000 - ₹2,66,000) x 17 = ₹90.78 lakh. Plus future income growth allowance (40-100%), funeral expenses, and consortium. Total: ₹1-1.5 crore.
Your ₹3,416/year TP premium protects you from ₹1 crore+ liability. Without it: you pay from personal assets, and courts can attach your property, salary, and bank accounts.
Top 10 Claim Rejection Reasons (And How to Avoid Each)
| Reason | How Often | How to Avoid |
|---|---|---|
| Invalid/expired driving license | Very common | Check license expiry every renewal. LMV endorsement is mandatory. |
| Delayed claim intimation (beyond 24-48 hours) | Common | Call insurer helpline from the accident spot. Get a claim number immediately. |
| Repairs started before surveyor inspection | Common | Never move the car to a garage before insurer assigns a surveyor |
| Undisclosed CNG/LPG kit | Common | Declare aftermarket modifications at the time of purchase or endorsement |
| Drunk driving | Common | Blood alcohol above legal limit = automatic rejection. No exceptions. |
| Using personal car for commercial purposes (Uber/Ola) | Growing | Personal policy does not cover commercial use. Need separate commercial vehicle policy. |
| Clubbing old damage with new claim | Growing | Insurers photograph your car at policy issuance. Old dents on new claims get flagged. |
| Policy lapsed at time of accident | Common | Set calendar reminders 30 days before expiry |
| Wrong information on proposal form | Occasional | Declare all modifications, previous claims, and accurate RTO details |
| Missing FIR for theft/major accident claims | Common | File FIR within 24 hours. Insist on a copy. |
Real Case: Universal Sompo Claim Rejection (2024)
Pramod Kumar Lohani’s car axle broke in a road accident. Universal Sompo rejected the claim citing missing FIR, license, and “no-liability certificate.” The West Singhbhum District Consumer Commission ruled this was deficiency in service and ordered Universal Sompo to pay ₹1.10 lakh compensation with 9% interest on delayed payment. Lesson: if your claim is wrongly rejected, the Insurance Ombudsman and Consumer Courts are effective escalation paths.
Used Car Insurance: 8 Gotchas Nobody Warns You About
-
IDV manipulation trap. Keeping IDV low to save premium backfires catastrophically on total loss or theft — you get the low IDV amount, not market value.
-
Cars over 5 years: IDV is negotiated. No formula exists. Disputes at claim time are common and ugly.
-
14-day transfer deadline. Insurance must be transferred within 14 days of vehicle purchase for continuous coverage. Miss it and you have a gap.
-
Pre-purchase inspection. Insurer may require physical inspection before issuing policy. Pre-existing damage is excluded permanently.
-
NCB does not transfer with the car. Previous owner’s NCB stays with them. You start at 0%.
-
Break-in insurance costs 10-20% more. If previous owner’s policy lapsed, you need a break-in policy requiring inspection and costing more.
-
Previous owner’s undisclosed modifications. CNG kit fitted but not declared? Your claim gets rejected — even though you did not fit it.
-
Salvage value deduction on total loss. Insurer pays IDV minus salvage value (what the wreck is worth). On a ₹3 lakh IDV car, salvage might be ₹80,000. You get ₹2.2 lakh.
Decision Framework: What to Buy Based on Your Car
| Your Situation | Recommended Cover | Add-Ons to Include | Annual Budget |
|---|---|---|---|
| New car, under 2 years, financed | Comprehensive | Zero-dep, RTI, Engine, Consumables, NCB Protection | ₹15,000-35,000 |
| Car 2-5 years, owned outright | Comprehensive | Zero-dep, Consumables, NCB Protection | ₹10,000-22,000 |
| Car 5-8 years, good condition | Comprehensive (basic) | Consumables only | ₹7,000-15,000 |
| Car 8-10+ years, low IDV | Third-party only | Personal Accident cover | ₹2,094-7,897 |
| Electric vehicle, any age | Comprehensive | Zero-dep, Battery Protection, Charger Cover, Engine | ₹15,000-50,000 |
| Second car, minimal use | Third-party only (if old) / Comprehensive (if new) | Based on car age | ₹2,094-20,000 |
How to Actually Compare and Buy (Without Getting Manipulated)
-
Calculate your IDV first. Use the depreciation table above. Do not accept insurer-suggested IDV without checking — they frequently undervalue by 10-20%.
-
Compare OD premium, not total premium. TP is identical everywhere. The only variable is OD premium and add-on pricing.
-
Check cashless garages near you. Go to each insurer’s website, enter your PIN code, and count garages within 10 km. This matters more than any premium difference.
-
Never buy from an aggregator without checking the insurer’s direct website. Aggregators earn 15-30% commission — some steer you toward higher-commission insurers, not better ones.
-
Read the policy wording document. Specifically check: deductible amounts, exclusion list, claim intimation deadline, and depreciation schedule. These are standardized per IRDAI, but add-on terms vary by insurer.
-
Renew before expiry. 90-day grace period for NCB is not a grace period for coverage. If your policy expires and you have an accident the next day, you have zero cover.
