Zero-depreciation car insurance: what it covers and whether it's worth it

You file an own-damage claim for a ₹60,000 repair, and the insurer pays around ₹47,000. Nothing went wrong. Your policy simply applied depreciation to the replaced parts, and you covered the difference. Zero-depreciation is the add-on that closes that gap, so a claim pays the full part value instead of a written-down one.

Here's exactly what it waives, the maths that makes it useful, and whether it's worth the extra premium for your car.

What zero-depreciation actually does

A standard own-damage policy doesn't pay the full price of a new part. It knocks off depreciation first, based on the part's material and your car's age, and you bear that slice on every claim. Zero-depreciation (also called nil-depreciation or bumper-to-bumper) removes that deduction. The insurer pays the full cost of the replaced parts, and the only thing left for you is the compulsory deductible.

It doesn't make the cover "total". It targets one specific, recurring cost: the depreciation that quietly shrinks every repair.

The depreciation it waives

Depreciation isn't uniform. It's heaviest exactly where cars get damaged most:

Part type	Standard depreciation
Rubber, plastic, nylon, tyres, tubes, batteries	~50%
Fibreglass components	~30%
Glass	0%
Metal / painted parts	By age (rises from ~5% to ~40-50% over the years)

Modern bumpers, panels and trims are full of plastic, so a knock that replaces them can attract a 50% deduction. That's the single biggest reason an own-damage claim pays less than the repair bill.

A worked example

Say a repair costs ₹60,000, of which ₹33,000 is parts, and your car has no zero-dep.

• Depreciation on the parts comes to roughly ₹13,000.
• Add your compulsory deductible of ₹1,000.
• The insurer pays about ₹46,000, and you pay around ₹14,000.

With zero-depreciation, that ₹13,000 depreciation disappears. You'd pay only the ₹1,000 deductible, and the insurer covers the rest. One add-on, on one claim, more than pays for itself.

Who should buy it

1. New and near-new cars. For a car under about five years, zero-dep is usually a clear win: small premium, large per-claim saving. Most insurers cap eligibility around the five-year mark.
2. Expensive or plastic-heavy cars. The pricier the parts, the more depreciation costs you, and the more the add-on returns.
3. High-traffic or flood-prone cities. More minor knocks means more claims where depreciation would otherwise bite.

On a very old car that's ineligible, or one you rarely claim on, it matters less. The point is to decide on the maths, not the marketing.

The fine print to check

Zero-dep isn't a blank cheque. Read these before you assume you're fully covered:

• Claim cap. Many policies limit the number of zero-dep claims per year (often one or two). Beyond that, normal depreciation returns.
• Compulsory deductible. You still bear it on every own-damage claim (₹1,000 for cars up to 1500cc, ₹2,000 above).
• Consumables. Engine oil, coolant and similar items usually need a separate consumables add-on.
• It isn't IDV or engine cover. Zero-dep waives part depreciation in a repair. It doesn't fix an understated IDV on a theft or total loss, and it doesn't cover flood engine damage. Those are different levers.

The bottom line

Zero-depreciation is one of the few add-ons that pays for itself in a single claim, because the depreciation it removes is steep and applies every time. For a newer car, it's usually worth it. Just know what it doesn't do: it won't cover your deductible, consumables, the engine, or an IDV gap. Buy it for what it is, the cure for depreciation, and pair it with the cover those other risks need.

FAQ

What is zero-depreciation car insurance? An add-on that waives the depreciation insurers deduct on replaced parts, so an own-damage claim pays the full part cost (minus your compulsory deductible).

Is zero depreciation worth it? For a car under about five years, usually yes. The premium is modest; depreciation on one claim can run into thousands. On an older car it matters less.

What does zero depreciation not cover? Your compulsory deductible, consumables (unless added), mechanical breakdown, engine/flood damage, or an IDV gap on theft/total loss. It also usually caps claims per year.

Does zero depreciation cover the engine? No. Water damage to the engine (hydrostatic lock) is consequential damage and needs a separate Engine Protect add-on.

Is bumper-to-bumper the same as zero depreciation? Yes. Bumper-to-bumper, nil-depreciation and zero-depreciation are the same add-on.
