Why Car Insurance Premiums Vary Across Regions in India
26 November, 2025
Car Insurance premiums in India don’t just depend on your car model or driving habits-your location also plays a major role. Your PIN code can significantly influence your insurance cost. This is because insurers use region-based risk segmentation to determine how likely a car is to face accidents, theft, or damage.
To understand why premiums differ from one place to another let’s break down the insurance zone system used in India.
What Are the Insurance Zones in India?
The Insurance Regulatory and Development Authority of India (IRDAI) divides regions into two major zones.
Zone A
Includes major metropolitan cities such as:
- Mumbai
- Delhi
- Chennai
- Bengaluru
- Kolkata
- Hyderabad
- Ahmedabad
- Pune
These cities are classified as high-risk due to dense traffic, higher accident frequency, and greater incidences of theft.
Zone B
Covers all other cities, towns, and rural areas.
These places generally experience lower traffic density and fewer claims making them lower-risk zones.
How Are Insurance Premiums Calculated in Each Zone?
The Own Damage (OD) premium-one of the key components of car insurance-is calculated as a percentage of your car’s Insured Declared Value (IDV). The percentage varies based on:
- Zone (A or B)
- Vehicle age
- Engine capacity (cc)
Below are the IRDAI-defined OD rates under the India Motor Tariff.
Zone A – OD Premium Rates
| Vehicle Age | ≤ 1000 cc | 1000–1500 cc | >1500 cc |
|---|---|---|---|
| Up to 5 years | 3.127% of IDV | 3.283% of IDV | 3.440% of IDV |
| 5–10 years | 3.283% of IDV | 3.447% of IDV | 3.612% of IDV |
| Over 10 years | 3.362% of IDV | 3.529% of IDV | 3.698% of IDV |
Zone B – OD Premium Rates
| Vehicle Age | ≤ 1000 cc | 1000–1500 cc | >1500 cc |
|---|---|---|---|
| Up to 5 years | 3.039% of IDV | 3.191% of IDV | 3.343% of IDV |
| 5–10 years | 3.191% of IDV | 3.351% of IDV | 3.510% of IDV |
| Over 10 years | 3.267% of IDV | 3.430% of IDV | 3.594% of IDV |
Zone A premiums are typically 10–15% higher than Zone B due to elevated risks in metropolitan areas.
Important:
Third-party premiums remain the same nationwide. They do *not* vary by zone.
Why Do Premiums Change Based on the Zone?
The primary reason is risk exposure.
Zone A Risks
- Heavy traffic
- Higher accident rates
- Increased frequency of claims
- Higher repair and labour costs
- More cases of theft or vandalism
Zone B Benefits
- Less congestion
- Lower accident probability
- Fewer claims
- Lower risk perception for insurers
Because of these differences insurers adjust OD premiums to reflect real-world risk profiles.
Other Factors That Affect Your Car Insurance Premium
While zones matter several other factors influence your final premium:
1. Insured Declared Value (IDV)
The current market value of your car. As your vehicle ages its IDV reduces-so does your OD premium.
2. Engine Capacity & Vehicle Class
Premiums vary based on engine capacity groups:
- Up to 1000 cc
- 1000–1500 cc
- Above 1500 cc
Private cars share the same premium structure while commercial vehicles follow separate tariffs.
Bonus: Electric cars get a 15% discount on third-party premiums as per IRDAI’s green vehicle policy.
3. Add-on Covers
Add-ons like:
- Zero Depreciation
- Engine Protection
- Roadside Assistance
increase your total premium.
4. Claim History
Making frequent claims removes your No Claim Bonus (NCB) increasing renewal premiums.

How to Reduce Your Car Insurance Premium
Even if you live in a high-premium metro you can still save money:
- Compare policies online before buying or renewing
- Install ARAI-approved anti-theft devices
- Choose a voluntary deductible
- Avoid filing small claims to protect your NCB
- Select only the add-ons you truly need
Smart choices can significantly reduce your overall insurance cost.
