When you buy or renew a motor insurance policy, one of the first things you notice is the premium. It is the amount you pay to keep your vehicle insured and protected. But have you ever wondered how that number is decided? Why does your friend with the same car pay a different premium than you? And what can you do to reduce the cost?
Understanding how motor insurance premiums are calculated can help you make smarter decisions and choose the best motor insurance plan that fits both your needs and your budget.
In this post, we break down the main factors that determine your premium and how you can optimize your policy without compromising on protection.
What Is a Motor Insurance Premium?
In simple terms, a motor insurance premium is the amount you pay to an insurance company in exchange for financial coverage against road risks, theft, natural disasters, third-party liabilities, and other potential losses involving your vehicle.
Premiums can vary widely depending on the type of policy, vehicle, driver profile, and additional coverage you choose. These variations are not random—they are calculated using specific guidelines set by the Insurance Regulatory and Development Authority of India (IRDAI) along with internal risk assessments done by insurers like Universal Sompo.
Main Factors That Influence Your Premium
1. Type of Policy Chosen
There are primarily two types of motor insurance:
- Third-Party Insurance: Mandatory by law in India. It covers only damages or injuries caused to another person or their property.
- Comprehensive Insurance: This includes third-party liability plus own damage cover, offering wider protection.
Comprehensive policies naturally have higher premiums because they provide more benefits.
2. Vehicle Details
The kind of vehicle you own plays a major role in determining the premium:
- Make and Model: A premium SUV will have a higher premium than a basic hatchback due to higher repair and replacement costs.
- Engine Capacity: Vehicles with larger engine capacity (measured in cubic centimeters or CC) attract higher premiums.
- Fuel Type: Premiums may differ slightly between petrol, diesel, CNG, or electric vehicles.
- Age of the Vehicle: Older vehicles usually have lower premiums for own damage because of depreciation, but they may be costlier to repair or replace parts.
3. Insured Declared Value (IDV)
The Insured Declared Value is the maximum amount your insurer will pay if your vehicle is stolen or declared a total loss. It is calculated based on the current market value of the vehicle after depreciation.
A higher IDV results in a higher premium, but it also means more financial protection in case of a complete loss. It is important to strike the right balance—do not understate the IDV just to lower the premium, because you will receive less compensation when you need it.
4. Location and Registration Zone
Your city or region of registration also affects your premium. Vehicles registered in metro cities or accident-prone zones usually attract higher premiums due to the increased risk of theft, vandalism, and collisions.
5. Add-On Covers
Add-ons are optional features that you can include in your policy for enhanced protection. Popular add-ons include:
- Zero depreciation cover
- Roadside assistance
- Engine protection
- Consumables cover
- Return to invoice
Each add-on comes with a small additional cost, increasing the total premium, but they offer significant value, especially in challenging driving conditions.
6. No Claim Bonus (NCB)
The No Claim Bonus is a discount offered by insurers for not making any claims during the policy year. It can reduce your premium by up to 50 percent over consecutive claim-free years.
NCB is applicable only on its own damage premium and not on third-party coverage. If you switch insurers, you can still retain your NCB, which makes it a valuable way to save on premiums.
7. Driver Profile and Usage
While this is more relevant for commercial vehicles or specialised coverage, personal driving habits may also influence risk evaluation:
- The age of the driver
- Experience and claim history
- Annual distance driven
- Vehicle usage (private, commercial, or ride-sharing)
Safer driving habits and fewer annual kilometers generally help keep your premium lower.
How to Lower Your Motor Insurance Premium
Now that you know what goes into calculating your premium, here are a few tips to reduce it without reducing coverage:
- Maintain a clean driving record
- Choose only necessary add-ons
- Install anti-theft devices approved by ARAI
- Opt for voluntary deductibles to share a small portion of the risk
- Renew your policy on time to retain your No Claim Bonus
- Compare policies online before buying or renewing
These steps may seem small but can lead to significant savings over time.
