The Hidden Depreciation Cost on Plastic Parts That Most Insurers Don’t Tell You Until You Crash

You buy car insurance thinking you are covered. You pick a plan, compare prices, maybe add a few extras, and move on with life. And honestly, that makes sense. No one wakes up excited to read policy documents.

But here’s something many drivers only learn after an accident. A large part of your repair bill can come from plastic parts. And standard car insurance usually cuts a big chunk of money from these parts because of depreciation. And that is where the surprise hits.

Let’s walk through what really happens and why it matters more than most people think.
 

The Car Parts You Don’t Notice

Modern cars use a lot of plastic. Strong, engineered material that helps reduce weight and improve fuel use. But insurance companies still treat it as fast-depreciating material. Plastic shows up in places like:

  • Bumpers
  • Grilles
  • Headlight housings
  • Interior panels
  • Wheel arch covers
  • Side mirror components

And these are not small add-ons. A bumper alone can cost thousands to replace, especially in newer cars with sensors. Now imagine this: Someone unfortunately gets into a minor crash and they think insurance will handle most of it. But only when the claim is processed, they are asked to pay a big part of the bill themselves.
 

What Depreciation Really Means During a Claim

Depreciation is simply the drop in value of a part over time. Insurers apply fixed depreciation rates based on material type and vehicle age. Plastic parts usually face the highest depreciation rate. In many standard policies, plastic can see depreciation up to 50% or more.

So if a plastic bumper replacement costs Rs. 20,000, your insurer may only pay Rs. 10,000. The rest comes from your pocket. Metal parts usually depreciate slower, rubber parts also follow different rates. But plastic gets hit hardest.
 

Why This Shock Comes After the Crash, Not Before

Insurance documents list depreciation rules. But let’s be honest. Most people do not read 30-page policy wordings. And even if you do, depreciation tables don’t always explain real-life impact. You only understand the cost when you see the repair estimate.

And by then, there is nothing you can change:

That is why many drivers think car insurance is “not paying properly,” when actually the policy is working exactly as written. It is just not explained in simple terms at purchase time.
 

The Rise of Expensive Plastic in Modern Cars

Cars today are packed with sensors, cameras, and advanced safety tech. Many of these sit behind plastic covers or inside plastic assemblies. Take modern bumpers. They are not just outer shells anymore. They may hold parking sensors, radar units, or driver assistance hardware.

Replacing these parts can get very expensive and depreciation still applies to the plastic shell portion. So repair bills are rising and depreciation deductions are rising along with them.
 

This Is Where Zero Depreciation Cover Changes Everything

Zero depreciation cover, also called bumper-to-bumper cover, removes depreciation cuts on most parts during claims. That includes plastic, rubber, and metal parts in many cases. So, if your bumper costs Rs. 20,000, and you have zero depreciation cover, the insurer may pay the full eligible amount, minus deductibles if any.

That changes your out-of-pocket cost dramatically. Many people skip this add-on to save on premium. But after one accident, they often wish they had taken it.
 

But There Is More Than Just Zero Depreciation

Some insurers also offer consumables cover. This handles small but necessary items used during repair like nuts, bolts, engine oil, grease, and similar materials. These costs add up fast during repairs. Standard policies usually do not cover them.

So, when you combine zero depreciation cover with consumables cover, your claim payout becomes much closer to the actual repair bill.
 

The Real-Life Example Most Drivers Relate To

Let’s say you own a three-year-old car and you unfortunately meet with a moderate front collision.

Repair estimate:

  • Bumper replacement: Rs. 25,000
  • Headlight plastic housing: Rs. 15,000
  • Clips, oils, small items: Rs. 5,000

Total: Rs. 45,000

  • Without zero depreciation, you might pay Rs. 15,000 to Rs. 20,000 yourself.
  • With zero depreciation and consumables cover, you might pay only deductibles, which are far lower.

That is a huge difference, especially when accidents already bring stress and disruption.
 

Why Insurers Don’t Always Highlight This?

Insurance pricing is competitive. Base policies look cheaper without add-ons. Thus, many buyers focus only on premium costs. And insurers do offer zero depreciation options. But buyers sometimes skip them to keep the premium low.

So the issue is not hidden on purpose. It is just not explained in a way that connects with daily driving reality. And most people only think deeply about insurance after a claim.
 

How To Choose Smarter When Buying Car Insurance?

You don’t need the most expensive plan. But you should look at real repair scenarios. Ask these questions:

  • How much depreciation applies to plastic parts?
  • Is zero depreciation cover available for my car age?
  • Is consumables cover offered?
  • How many claims allow zero depreciation use per year?

These questions can save serious money later. And at SMC Insurance, the goal is simple. Help you compare multiple insurers in one place and see what each plan really offers, not just the price.

Since SMC partners with many leading insurers, you can check:

  • Zero depreciation availability
  • Consumables cover options
  • Claim support quality
  • Premium differences across insurers

Wrapping Up,

Plastic parts are everywhere in modern cars. And they are expensive. Standard insurance treats them as fast-losing value items. So when an accident happens, depreciation can turn a “covered repair” into a large personal expense. Mostly this is the hidden cost most drivers never see coming. A good insurance policy that offers protection from surprise bills after accidents. And sometimes, truly this one add-on decides that difference.

FAQs

Depreciation is the reduction in value of car parts as they age. During a claim, insurers deduct this value from the repair payout, especially for plastic parts.

Plastic parts are seen as faster-wearing materials. So insurers apply higher depreciation rates to them compared to metal parts.

Zero depreciation cover is an add-on that removes depreciation cuts during claims. This means the insurer pays a higher share of repair costs for parts like plastic and rubber.

For many drivers, yes. One accident can lead to large repair costs. Zero depreciation cover can reduce out-of-pocket expenses during claims.

Consumables cover pays for small repair items like nuts, bolts, oil, and grease. These items are usually not covered in standard car insurance but can add to the final repair bill.
