Car insurance is essential for protecting yourself financially against accidents, theft, or damage to your vehicle. It provides peace of mind and ensures that unexpected costs don’t derail your budget.
In this guide, we will explain how to calculate the right car insurance premium to help you find the best coverage at a fair price.

Why Use a Car Insurance Premium Calculator?

Using a car insurance premium calculator before purchasing or renewing a policy offers several key benefits:

  • Budget Planning: It helps you determine the expected cost in advance, allowing you to plan your budget accordingly.
  • Customisation: You can adjust the IDV or add or remove add-ons to find a premium that fits your needs and budget.
  • Smart Comparison: The calculator enables you to quickly compare quotes from multiple insurers to find the most cost-effective car insurance plan.
  • Transparency: It helps you understand how each element affects your premium, offering clarity and control.
  • Avoid Overpaying: A calculator protects you from inflated or misleading premium quotes by giving you an accurate estimate.

How is the Car Insurance Premium Decided?

The amount you pay for your car insurance depends on multiple elements, such as:

  • Type of Insurance: Whether you opt for third-party, own-damage, or a comprehensive policy.
  • Vehicle Details: The car’s make, model, fuel type, age, engine capacity, and location of registration.
  • Car Value (IDV): A higher Insured Declared Value (IDV) leads to a higher premium.
  • Add-on Covers: While helpful, optional add-ons such as zero depreciation, engine protection, or roadside assistance can increase the overall premium.

Factors That Might Affect Your Car Insurance Premium

Multiple factors influence the car insurance premium, especially under the Own Damage Section.
Here are the elements that insurance providers might consider:

1. Insured Declared Value (IDV)

IDV is the current market value of the car and represents the maximum claim amount the insurer will pay in case of total loss or theft.
It is calculated using the formula:
IDV = Manufacturer’s listed price- Depreciation (as per schedule)
For example: depreciation is 5% for cars under 6 months old and up to 50% for those over 10 years old.

2. Make and Model of the Vehicle

Premiums are higher for luxury cars or sports vehicles due to their expensive parts and repair costs.
Cars with lower cubic capacity and standard features have lower premiums.

3. Age of the Vehicle

As a car ages, its value depreciates, reducing the IDV and thereby lowering the Own Damage premium.
However, older cars may also attract higher premiums due to increased chances of breakdowns.

4. Geographical Location

Cars registered in metropolitan or accident-prone zones usually attract higher premiums.
Areas with high theft rates also lead to increased insurance costs.

5. Driving History and Claims Record

A clean driving record with minimal or no claims can significantly reduce the premium through the No Claim Bonus (NCB).
Policyholders with consistent claim-free years can earn up to 50% NCB savings on their Own Damage premium.

6. Installation of Safety Devices

Anti-theft devices approved by the Automotive Research Association of India (ARAI) can help lower premiums by reducing risk.

How to Use a Car Insurance Premium Calculator?

A car insurance premium calculator is an online tool that allows users to estimate their premiums based on key vehicle and policy details.

Here’s how it typically works:

Step 1: Enter Basic Vehicle Information

Provide the car's registration number, make, model, fuel type, and year of manufacture.
For new vehicles that have not yet been registered, the RTO code and state details are required.

Step 2: Adjust IDV and Add-Ons

Users can modify the IDV to see how it affects the premium.
Add-ons such as Zero Depreciation, Roadside Assistance, and others can be included based on specific requirements.

Step 3: Review the Quote

The calculator provides an instant estimate based on the inputs.
Users can compare premiums with and without add-ons to determine which option best fits their budget.

Step 4: Proceed to Buy or Renew Online

If satisfied, the policy can be purchased or renewed online directly through the insurer’s website.

Tips to Reduce Car Insurance Premium

Here are a few pointers that may help reduce your Car Insurance Premium.

  • Opt for Higher Deductibles: This lowers the premium by requiring you to share more out-of-pocket expenses during claims.
  • Avoid Small Claims: This helps retain the No Claim Bonus (NCB), which significantly reduces future premiums.
  • Install Safety Devices: Approved anti-theft systems can fetch additional savings.
  • Bundle Policies: Insuring home and vehicle with the same provider may offer combined savings.
  • Buy Online: Purchasing policies through digital platforms often comes with exclusive offers.
  • Limit Modifications: Fancy upgrades may look great but increase risk and premium.
