Zero Depreciation vs Standard Car Insurance: The Numbers
By Nitish Bharadwaj · Published May 30, 2026 · 4 min
Zero depreciation car insurance eliminates the depreciation deduction on replaced parts during a claim, typically increasing the claim payout by ₹15,000–40,000 for a mid-size sedan. The add-on costs ₹3,000–8,000 extra annually. This article calculates the breakeven point, identifies the car age and model scenarios where zero dep pays for itself, and explains why it is most valuable in the first four years of car ownership.
When your car gets scratched or dented, the insurer deducts "depreciation" from your claim — which can be 30–50% for older cars. Zero Depreciation add-on eliminates this deduction. But is it worth the extra premium? If you're still paying a car loan, most lenders require comprehensive cover — so this decision is especially relevant for new-car owners.
| Parameter | Standard Comprehensive | With Zero Depreciation |
|---|---|---|
| Depreciation on parts | 10–40% deducted from claim | No deduction — full part cost paid |
| Premium increase | Base premium | +15–20% of base premium |
| Best for | Cars > 5 years old (diminishing returns) | Cars 0–5 years old |
| Max claims | Unlimited | Usually 2 claims/year |
How Depreciation Is Actually Calculated on a Claim
Standard comprehensive insurance uses IRDAI-approved depreciation schedules tied to the age of the replaced part, not the car itself. Plastic, rubber, and fibre parts depreciate at 30% in years 1–6 and 40% beyond that. Metal parts depreciate at 0–5% in year one but climb to 30%+ by year five. On a typical minor accident — a bumper replacement, damaged headlights, and a cracked side panel — the depreciation deduction on a 4-year-old car often runs ₹15,000–30,000. The garage invoice looks fine; your final reimbursement does not. Zero depreciation cover removes this deduction entirely: the insurer pays the full market cost of the replacement part without any depreciation cut. The trade-off is that most insurers cap zero dep claims at two per year — a third accident in the same year would be settled on the standard depreciated basis.
How Much the Add-On Actually Costs
The premium for zero depreciation cover depends on the car's insured declared value (IDV) and age, but a rough benchmark: for a car in the ₹6–12 lakh on-road range in its first 3 years, zero dep typically adds ₹1,500–4,000 to your annual premium — roughly 10–20% of the base own-damage premium. On the same car, one bumper replacement claim without zero dep might cost you ₹8,000–20,000 in depreciation deductions. The add-on pays for itself with a single meaningful claim, which is why it is almost universally recommended for cars in their first 3–4 years.
Other Add-Ons Worth Considering Alongside Zero Dep
- Engine and gearbox protection: covers internal engine damage from water ingestion or oil leakage — not covered under a standard policy. Worth adding in flood-prone cities or if you're buying an EV (battery damage is a separate coverage question).
- Return to Invoice (RTI): if your car is declared a total loss or stolen, RTI pays the original on-road price instead of the depreciated IDV. Useful in the first 2–3 years when the IDV is well below what you paid.
- Roadside assistance (RSA): covers towing, flat tyre help, and emergency fuel. Usually costs ₹300–700/year — cheap enough to include on any car regardless of age.
- No-Claim Bonus protection: lets you make one claim per year without losing your accumulated NCB. Useful if your NCB is above 25%.
Our Recommendation
- Car 0–5 years: Buy zero dep add-on. Clear value — one repair claim typically recovers several years of add-on premium.
- Car 5–10 years: Calculate the premium increase against your estimated repair frequency. At this age, the depreciation deduction on metal parts is large enough that zero dep can still pay off, but verify the add-on is still offered (some insurers stop offering it on older cars).
- Car > 10 years: Skip zero dep. The car is likely worth less than major repair costs, making a total loss settlement more likely than a partial repair. Depreciation saving on a partial claim matters less at this valuation.
Frequently Asked Questions
What is zero depreciation car insurance and do I need it?
Zero depreciation cover (also called nil dep or bumper-to-bumper cover) is an add-on to your comprehensive policy that removes the insurer's right to deduct depreciation on replaced parts. Without it, a 3-year-old car's plastic bumper replacement sees a 30% deduction on the part cost — you pay that gap out of pocket. If your car is under 5 years old, zero dep is almost always worth adding.
Does zero depreciation cover tyres and batteries?
Generally no. Most zero dep policies explicitly exclude tyres, batteries, and consumables like engine oil and coolant from the no-depreciation benefit. These items are depreciated under the standard schedule regardless of whether you have zero dep cover. Check your policy wording for the exact exclusion list before buying.
What is the IDV of my car and how does it affect my insurance?
IDV (Insured Declared Value) is the maximum amount your insurer will pay if your car is stolen or declared a total loss — roughly the current market value of your car. It is recalculated at each renewal using IRDAI depreciation rates on the ex-showroom price. A lower IDV means a lower own-damage premium but also a lower payout in case of total loss. Return to Invoice (RTI) cover bridges the gap between IDV and the original price you paid.
