When a car is repaired after an accident, the insurer doesn’t pay the full cost of replacing damaged parts. Under standard comprehensive motor insurance, the claim settlement accounts for depreciation — the reduction in value of parts due to age and wear — and pays only the depreciated value. For a new car, this means the policyholder pays a meaningful portion of every repair bill out of pocket, despite holding what appears to be comprehensive coverage.
Zero Depreciation — also called Nil Depreciation or Bumper-to-Bumper cover — eliminates this deduction. When the add-on is in force, the insurer pays the full cost of parts replacement without applying any depreciation factor. For new car owners, this single add-on can make the difference between an insurance claim that genuinely covers the loss and one that leaves a significant shortfall.
How Depreciation Affects Standard Claims
Under standard comprehensive insurance, parts replaced during repair are subject to depreciation rates defined by IRDAI based on the age of the vehicle. For vehicles less than six months old, depreciation is nil — but it rises progressively. Rubber, plastic, and fibre components attract 50% depreciation regardless of vehicle age. For a vehicle between one and two years old, metal parts attract 10% depreciation, rising to 20% for two to three years, and continuing upward with age.
On a repair bill of ₹80,000 involving significant plastic body panel replacement, rubber components, and metalwork on a two-year-old car, the depreciation deductions can reduce the insurer’s payment to ₹55,000 to ₹60,000 — leaving ₹20,000 to ₹25,000 for the owner to fund from pocket. This is not a negligible amount, and it repeats on every Own Damage claim throughout the policy period.
Zero Depreciation removes these deductions entirely. The insurer pays the full parts replacement cost, and the policyholder’s out-of-pocket expense is reduced to any applicable compulsory excess — typically ₹1,000 for private cars.
What Zero Depreciation Covers and What It Doesn’t
The add-on covers the depreciation deduction on replaced parts for Own Damage claims arising from accidents, fire, and natural calamities. It does not alter coverage for theft, total loss situations, or exclusions in the standard policy — driving under the influence, unlicensed driving, and mechanical breakdown remain outside the policy’s scope regardless of the add-on.
Some insurers exclude certain components even under zero depreciation — tyres, batteries, and engine oil typically remain subject to standard depreciation or are covered under separate add-ons. Confirm the specific inclusions and exclusions with your insurer before assuming full blanket coverage.
The Premium Cost and Value Calculation
Zero Depreciation adds approximately 15% to 20% to the Own Damage premium component of your comprehensive policy. For a new mid-range car with an OD premium of ₹12,000, the add-on costs approximately ₹1,800 to ₹2,400 annually.
Against this cost, consider the depreciation saving on a single moderate accident — new cars in urban traffic environments average at least one significant scratch or panel damage incident in the first three years. A single repair bill where the add-on saves ₹15,000 to ₹20,000 in depreciation deductions pays for three to four years of the add-on premium with one event. The value case for new car owners is straightforward.
When the Add-On Is Most Valuable
Zero Depreciation delivers maximum value in the first three to five years of vehicle ownership — when the vehicle’s parts still command near-full replacement cost and the depreciation deductions are most impactful relative to the vehicle’s value. After five years, parts costs are lower, the OD premium itself has reduced with the depreciating Insured Declared Value, and the absolute saving from the add-on diminishes.
Most insurers offer Zero Depreciation for vehicles up to five years old — some up to three years. After this age ceiling, the add-on is typically unavailable, which coincides naturally with the period when its value was highest.
Claims Limit Per Policy Year
Most insurers cap the number of Zero Depreciation claims at two per policy year. A third Own Damage claim in the same year reverts to standard depreciation deduction. This limit is a practical constraint for very frequent claimants but doesn’t affect the majority of policyholders who file one or at most two claims in a year.
Understanding this limit prevents the surprise of discovering depreciation deductions on a third claim after assuming full coverage throughout the year.
Frequently Asked Questions (FAQs)
Q1. Can Zero Depreciation be added to an existing policy mid-year, or only at renewal?
A: Zero Depreciation is typically available only at policy inception or renewal — it cannot be added mid-year to an existing policy. If you purchased comprehensive insurance without the add-on and want to include it, the earliest opportunity is your next renewal. This reinforces the importance of evaluating all relevant add-ons at the time of initial purchase rather than attempting to add them after the policy is in force.
Q2. Does Zero Depreciation cover total loss or theft claims?
A: No. In total loss situations — where the repair cost exceeds a defined percentage of the Insured Declared Value — the insurer settles on IDV basis under the standard policy terms. Zero Depreciation does not increase the IDV or change the settlement basis for total loss. For theft claims, the IDV is the settlement amount regardless of add-ons. Zero Depreciation applies specifically to partial loss — repair claims where specific parts are replaced.
Q3. Is Zero Depreciation the same as a Return to Invoice add-on?
A: No, these are different add-ons addressing different gaps. Zero Depreciation covers depreciation deductions on parts during repair claims. Return to Invoice cover addresses the gap between the Insured Declared Value — which depreciates from the car’s purchase price over time — and the original invoice price, paying the on-road purchase price in a total loss scenario rather than the lower IDV. For comprehensive protection, many new car owners purchase both add-ons together.
Q4. Does using the Zero Depreciation add-on affect my No Claim Bonus?
A: Yes. Any Own Damage claim — regardless of whether Zero Depreciation is used — resets the NCB to zero at renewal. The Zero Depreciation add-on increases the claim settlement amount but does not protect the NCB. For this reason, many insurers also offer an NCB Protect add-on separately. Combining Zero Depreciation with NCB Protect provides both full parts cost recovery and NCB preservation for one claim per year.
Q5. Is Zero Depreciation available for commercial vehicles and two-wheelers?
A: Zero Depreciation add-ons are available for two-wheelers in addition to private cars — the mechanics and value proposition are identical. Availability for commercial vehicles varies by insurer and vehicle type. For private car and two-wheeler owners, the add-on is widely available from all major general insurers and is increasingly offered as a standard bundle in first-year comprehensive policies for new vehicles, sometimes without explicit selection required.
The Bottom Line
All three articles in this set address the same underlying challenge — the gap between what policyholders assume their insurance covers and what it actually does. Reading a policy document properly closes the information gap before a claim. Understanding PED waiting periods prevents the shock of a rejected claim for an undisclosed condition. And Zero Depreciation ensures that a comprehensive motor policy delivers genuinely comprehensive repair coverage rather than a partially funded settlement. In every case, ten minutes of attention at the right time is worth considerably more than the hours of frustration that uninformed policyholders experience when a claim doesn’t go as expected.
