Zero Depreciation Car Insurance: Is the Add-On Worth It?

Zero depreciation (zero dep or bumper-to-bumper) is an add-on to comprehensive car insurance that removes the depreciation insurers otherwise deduct on replaced parts, so you get close to the full repair bill minus a small deductible. It typically costs around 15% to 20% more on the own damage premium, and for a car up to about five years old it usually pays for itself with one moderate claim. It is less useful once the add-on stops being offered or the car's value falls.

If you are still choosing between third-party and full cover, read third-party vs comprehensive car insurance first. This article assumes you have comprehensive cover.

How depreciation cuts a normal claim

In a standard own damage claim, the insurer pays for replaced parts after deducting depreciation. The standard schedule used in Indian motor policies (as of October 2026):

Metal parts depreciate with the car's age:

Modern cars use far more plastic, from bumpers to grilles and lamp housings, so the 50% cut on plastic hurts even on a new car.

Worked example: same accident, two car ages

A front-end collision needs: bumper and grille (plastic) ₹28,000, bonnet and fender (metal) ₹32,000, headlamp assembly (plastic) ₹18,000, labour ₹14,000. Total bill: ₹92,000. The car is below 1,500cc, so the compulsory deductible is ₹1,000.

Car aged 1.5 years

Car aged 4.5 years

The add-on saves ₹26,200 on the newer car and ₹34,200 on the older one. If the own damage premium is ₹10,000 and zero dep adds 20% (₹2,000 a year), a single claim like this covers more than a decade of add-on cost. (Illustrative; actual premiums and depreciation follow your policy.)

Break-even thinking

The add-on is worth it if:

Expected saving per claim × chance of a claim in the year > extra premium

If zero dep costs ₹2,000 and a typical claim would otherwise leave you paying ₹20,000 more, you only need about a 1-in-10 chance of claiming in a year to break even. City drivers who park on the street usually exceed that.

Limits and exclusions

• Claims per year: most insurers allow a limited number of zero dep claims per policy year, commonly two. Extra claims are settled with normal depreciation.
• Car age limit: many insurers offer zero dep only for cars up to 5 years old; some extend to 7 years, often at higher cost.
• Renewal continuity: some insurers offer zero dep on an older car only if the expiring policy also had it.
• Not covered: tyres and tubes (unless damaged along with the vehicle in an accident, as per wording), mechanical and electrical breakdown, wear and tear, engine damage from driving through water, consumables like oil and nuts and bolts, and claims where the driver lacked a valid licence or was drunk.
• Deductibles still apply: the compulsory deductible (commonly ₹1,000 up to 1,500cc and ₹2,000 above) is not waived.

Useful companion add-ons

Buy add-ons that match real risks: engine protect in flood-prone cities, return to invoice for a new car on a loan.

When to drop zero depreciation

Zero dep stops being good value when:

• The insurer no longer offers it because the car has crossed its age limit, or the premium loading becomes steep
• The car's IDV is low and you would probably repair minor damage yourself rather than claim
• You drive rarely and park in a secure, covered spot
• You are planning to sell the car within a few months

At that point, a comprehensive policy without zero dep, with a modest voluntary deductible to lower premium, can be the sensible middle ground. For a very old car, compare it with third-party only cover.

Questions to ask before buying the add-on

Before paying for zero dep, get clear answers to these, ideally in the policy schedule rather than a sales call:

1. How many zero dep claims are allowed in the policy year?
2. Up to what car age will the insurer renew zero dep, and does it require continuous zero dep cover?
3. Are fibreglass, batteries and airbags included in the nil-depreciation benefit?
4. Is there a separate deductible or co-payment for zero dep claims?
5. Which network garages offer cashless repairs near you?

Garage choice matters as much as the add-on. A cashless network garage settles directly with the insurer; a non-network garage means paying first and claiming reimbursement.

Should you claim small repairs?

Zero dep makes claims cheap, but each claim can still cost your no claim bonus, which reduces own damage premium by 20% after one claim-free year up to 50% after five (as of October 2026). For a ₹5,000 scratch repair, the NCB you lose at renewal may cost more than the repair. Keep small repairs out of claims unless you also hold an NCB protector.

Is zero dep worth it on a loan-financed car?

For a new car on a loan, yes in most cases. A large repair bill on top of your EMI strains cash flow; a ₹35,000 shortfall is about 2.5 months of EMI on a ₹7 lakh, 5-year loan at 9.5%. Check your own EMI with the EMI calculator, and see the car loan guide for how lenders treat insurance.

Cost, GST and complaints as of October 2026

• Motor insurance, including add-ons, carries 18% GST as of October 2026; the September 2025 exemption covered only individual life and health insurance.
• If an insurer deducts depreciation despite the add-on, or wrongly counts a claim against your limit, write to its Grievance Redressal Officer, then escalate through IRDAI's Bima Bharosa portal and the Insurance Ombudsman (for disputes up to ₹50 lakh). See insurance claim rejected reasons.

Key takeaways

• Without zero dep, insurers deduct 50% on plastic and rubber parts and up to 50% on metal parts by age.
• One moderate claim can save ₹25,000 to ₹35,000, far more than the yearly add-on cost.
• Expect a cap on zero dep claims per year (often two) and an age limit around 5 years.
• The compulsory deductible still applies; tyres, engine water damage and breakdowns need other add-ons.
• Avoid claiming small repairs that would cost you more in lost no claim bonus.
