If you're driving on the roads, chances are you've got car insurance. But have you ever wondered about the term "sum insured" that pops up when you're sorting out your policy? Whether you've got comprehensive, third-party fire and theft, or third-party only insurance, understanding your sum insured is key. Let's dive into what car insurance sum insured means and why it matters for your policy.

What is Car Insurance Sum Insured?

The sum insured, also known as the insured amount, refers to the maximum amount an insurance company will pay out if you make a claim. It's the financial safety net that protects you if something goes wrong with your car. This could be anything from an accident to theft or fire damage.

Here's the lowdown:

  • For brand-new cars, the sum insured is usually set at 80% of the car's value
  • This amount typically decreases by about 10% each year
  • The exact sum insured can vary based on the current market value of your car model

It's important to note that the sum insured is typically lower than the actual market value of your car. Insurance companies factor in depreciation and other variables when determining the insured amount.

How is Sum Insured Calculated?

The calculation of the sum insured can vary between insurance companies, but generally, it follows these principles:

For new cars:
Sum insured = 80-85% of the car's invoice price

For used cars:
Sum insured = Current market value of the car - Annual depreciation

The annual depreciation rate is usually around 10-15%, but this can vary based on factors like:

  • Make and model of the car
  • Age of the car
  • Overall condition
  • Market demand for that particular model

Some insurers use specialised tools or databases to determine the current market value of used cars, ensuring a more accurate sum insured.

Example Calculation

Let's say you bought a new car for 1,000,000 baht:

  • Year 1 sum insured: 1,000,000 x 80% = 800,000 baht
  • Year 2 sum insured: 800,000 - 10% = 720,000 baht
  • Year 3 sum insured: 720,000 - 10% = 648,000 baht

Remember, these are general guidelines, and actual calculations may vary between insurance providers.

How Does Car Insurance Sum Insured Affect Your Premium?

Your sum insured directly impacts how much you'll pay for your insurance. Here's how it works:

  • Higher sum insured = Higher premium
  • Lower sum insured = Lower premium

But it's not just about the numbers. When deciding on your sum insured, consider:

  • How often do you use your car
  • The routes you usually drive (are they high-risk?)
  • Your driving experience

Adjusting Your Sum Insured

You can actually tweak your sum insured to suit your needs:

  • Increase it by up to 50,000 baht if you feel you need extra protection
  • Decrease it by up to 50,000 baht if you want to lower your premium

Remember, these changes will affect your premium accordingly.

How to Choose the Right Sum Insured for You

Picking the right sum insured isn't a one-size-fits-all deal. It depends on:

  • Your driving skills
  • The age of your car

For New Drivers with New Cars

If you're new to driving and have a brand-new car, a higher sum insured might be your best bet. It offers:

  • More comprehensive protection
  • Higher payouts if accidents happen

For Experienced Drivers with Older Cars

If you've got years of driving under your belt and your car isn't fresh off the lot, you might consider a lower sum insured to keep your premiums down.
