Car insurance add-ons are optional benefits that extend the protection available under an eligible motor insurance policy. Popular options include zero depreciation, engine protection, return to invoice, consumables cover, No Claim Bonus (NCB) protection and roadside assistance. The right add-ons depend on your car’s age, value, driving conditions and budget. Compare each benefit’s price, exclusions, claim limits and eligibility before paying extra.
Quick Answer: Which Car Insurance Add-ons Are Worth Buying?
Zero depreciation may be useful for newer cars, engine protection for vehicles exposed to certain water-related risks, and roadside assistance for drivers who travel frequently. Return-to-invoice cover may suit eligible new cars, while consumables and NCB protection can help with specific out-of-pocket costs. No add-on is essential for everyone. Compare the extra premium with the benefit, exclusions and claim conditions before choosing.
Key Takeaways
- Add-ons extend specific benefits; they do not remove every exclusion in a standard car insurance policy.
- Zero depreciation can reduce specified depreciation deductions on eligible parts.
- Engine protection may cover defined engine or gearbox damage that standard cover does not include.
- Return-to-invoice cover may provide a benefit linked to the original invoice value after a qualifying total loss or theft.
- Consumables cover can pay for eligible items used during covered repairs.
- NCB protection may preserve your eligible renewal discount under specified conditions.
- Roadside assistance provides defined emergency services, subject to service limits.
- Always check the insurer’s policy wording, eligibility rules and claim limits before buying.
What Are Car Insurance Add-ons?
Car insurance add-ons are optional benefits that provide additional protection beyond the standard policy, subject to eligibility and the terms of the selected product.
For example, a comprehensive car insurance policy may cover eligible accident damage, but depreciation deductions can reduce the amount payable for certain replacement parts. A zero-depreciation add-on may reduce those deductions for eligible claims.
Similarly, standard own-damage cover may exclude certain mechanical breakdown or water-ingress losses. An engine-protection add-on may cover specified additional risks under its own conditions.
Add-ons are usually available for an extra premium. Some may be restricted by vehicle age, model, policy type, claim history or other eligibility requirements.
They are not a substitute for the underlying insurance policy. You generally need eligible own-damage or comprehensive cover to purchase add-ons that extend protection for your own vehicle.

Car Insurance Add-ons: Detailed Comparison Table
The following table compares common add-ons, their potential benefits, typical users and important limitations. Actual cover and pricing vary by insurer and policy.
| Add-on | What it generally covers | Who may benefit? | Main limitation to check | Worth considering when |
| Zero depreciation | Reduces or waives specified depreciation deductions on eligible parts | Owners of newer cars | Age restrictions, claim limits, excluded parts and deductibles | Replacement parts are expensive |
| Engine protection | Covers specified engine or gearbox damage under defined circumstances | Drivers in flood-prone areas | Covered causes, exclusions and maintenance conditions | Water ingress or certain engine-related risks are a concern |
| Return to invoice | Provides a benefit linked to the original invoice or specified vehicle value after a qualifying total loss or theft | Owners of eligible new cars | Eligibility period, settlement formula and exclusions | Replacing a new car would create a significant financial burden |
| Consumables cover | Covers eligible consumables used during covered repairs | Owners seeking to reduce small repair expenses | Items included, limits and exclusions | Repair bills include significant eligible consumables |
| NCB protection | Preserves eligible No Claim Bonus under specified claim conditions | Drivers who want to protect their renewal discount | Permitted claims, eligibility and bonus rules | Losing an accumulated discount would be costly |
| Roadside assistance | Provides specified breakdown and emergency services | Frequent travellers and daily commuters | Towing limits, service availability and response conditions | You regularly travel long distances |
| Tyre protection | Covers specified tyre or wheel damage under the add-on terms | Owners with expensive tyres or rims | Damage types covered, exclusions and replacement limits | Tyre replacement costs are high |
| Key and lock protection | Covers specified key replacement or lock-related expenses | Owners with expensive smart keys | Claim limits, covered incidents and documentation | Replacement keys are costly |
| Personal belongings cover | Covers specified personal items damaged or stolen from the insured vehicle | Drivers who regularly carry valuable permitted belongings | Item limits, proof requirements and exclusions | The policy’s benefit meaningfully addresses your needs |
| Daily allowance or garage cash | Provides a defined benefit during eligible repairs or vehicle downtime | Drivers who depend on their car daily | Repair-duration requirements, claim limits and exclusions | Alternative transport costs are a concern |
These are general descriptions, not guaranteed benefits across all insurers. Check the individual add-on wording and prospectus for the exact coverage.
Zero Depreciation Cover: Is It Worth Paying For?
Zero depreciation cover, also called nil depreciation or bumper-to-bumper cover in some marketing materials, reduces or waives specified depreciation deductions on eligible parts during a covered repair claim.
Without this add-on, the insurer may deduct depreciation from certain replaced parts according to the policy’s rules. With eligible zero-depreciation cover, the insurer may pay a higher proportion of the eligible parts cost.
Example
Suppose your car needs ₹30,000 in eligible replacement parts after a covered accident. If depreciation deductions would otherwise apply, you may have to pay part of that cost yourself. A zero-depreciation add-on may reduce those deductions, but the actual saving depends on the policy, deductible and claim assessment.
Who should consider it?
- Owners of newer cars.
- Drivers of vehicles with expensive replacement parts.
- Owners who want to reduce depreciation-related out-of-pocket expenses.
- Drivers who frequently use their cars in busy traffic.
What does zero depreciation not cover?
It generally does not turn an excluded loss into a covered one. Depending on the policy, limitations may include:
- Compulsory or voluntary deductibles.
- Mechanical breakdown not covered by the base policy.
- Consumables unless separately covered.
- Total-loss claims, which may be handled under different policy provisions.
- Tyres and tubes unless specifically included.
- Claims exceeding the permitted number or other stated conditions.
ACKO’s published zero-depreciation wording, for example, limits the benefit to eligible partial-loss claims and specifies exclusions for certain tyre-related depreciation and total-loss situations. Other insurers may use different terms.
For more details, read Zero Depreciation Cover: How It Works and Who Needs It.
Engine Protection Cover: What Does It Cover?
Engine protection is an optional benefit designed to cover specified engine or gearbox damage that may not be covered under a standard own-damage policy.
Depending on the wording, it may cover certain damage arising from water ingress, lubricant leakage or other defined circumstances.
Who should consider engine protection?
It may be worth considering if:
- You live in a flood-prone area.
- Your car is expensive to repair.
- You regularly drive through areas where waterlogging is common.
- You want protection against specific engine-related risks excluded from your base cover.
Important limitations
Engine protection is not a general warranty for every engine problem. The policy may exclude ordinary wear and tear, pre-existing damage, improper maintenance, or damage caused by continuing to operate the engine after a warning or water-ingress event.
Follow the insurer’s instructions if your car stalls in standing water. Attempting to restart a flooded engine can worsen the damage and may affect claim eligibility.
ACKO’s official product information describes engine protection for specified engine, gearbox and differential damage, including certain water-ingress and oil-leakage circumstances. The exact covered events depend on the issued policy.

Return to Invoice Cover: When Is It Useful?
Return-to-invoice (RTI) cover is an add-on that may provide a benefit linked to the original invoice value or another defined vehicle value after a qualifying theft or total-loss claim.
The amount payable depends on the policy’s formula and conditions. It should not be assumed that every expense associated with buying a replacement car will be reimbursed.
Example
Suppose you bought a car for ₹10 lakh, and its IDV has fallen to ₹7.5 lakh over time. If the car is stolen and not recovered, a qualifying RTI benefit may cover some of the difference between the IDV-based settlement and the value defined in the add-on.
The actual settlement depends on the policy’s definition of invoice value, applicable taxes and registration costs, eligibility period and exclusions.
Who may benefit?
RTI may be worth considering for owners of eligible new cars who would face a significant financial gap if the vehicle were stolen or declared a total loss.
Before buying, check:
- The maximum eligible vehicle age.
- Whether theft and total loss are both covered.
- How the insurer calculates the benefit.
- Whether registration charges and road tax are included.
- Whether the benefit has a maximum limit.
ACKO’s published comparison explains RTI as cover for the difference between IDV and the original invoice value following a qualifying total loss. Exact terms vary by product.

6. Consumables Cover: What Does It Pay For?
Consumables cover can pay for specified small items used during a covered repair that may otherwise be excluded from the standard own-damage settlement.
Depending on the policy, these may include:
- Engine oil and lubricants.
- Coolant and certain other fluids.
- Nuts, bolts, screws and washers.
- Oil filters and specified similar items.
- Grease and other listed consumables.
The exact list differs by insurer. Consumables cover generally applies only when the underlying own-damage claim is accepted and the items meet the add-on’s conditions.
Is consumables cover worth buying?
It may be useful if you want to reduce eligible out-of-pocket expenses during repairs. However, it is less valuable if the premium is high compared with the likely benefit.
Check whether the add-on covers the items listed in your garage’s estimate and whether it imposes limits or exclusions.
ACKO’s official add-on information identifies items such as engine oil, lubricants, nuts and bolts among the consumables that may be covered under its product terms.

7. NCB Protection Cover: Can It Save Your Renewal Discount?
No Claim Bonus (NCB) is a renewal discount generally earned for eligible claim-free own-damage policy periods. An NCB-protection add-on may allow you to retain the eligible discount after certain claims, subject to the add-on’s conditions.
Without NCB protection, a claim may affect your bonus at renewal. With the add-on, the insurer may preserve the bonus for permitted claims, but it does not guarantee that every claim will leave the discount unchanged.
Example
Suppose you have accumulated a 35% NCB discount on the eligible own-damage premium. You then make a covered claim for accident damage. If your policy’s NCB-protection conditions are met, the add-on may allow you to retain the eligible discount at renewal.
The actual benefit depends on the insurer’s rules, permitted number of claims and the policy schedule.
When is NCB protection worth it?
Consider it when:
- You have accumulated a substantial NCB.
- You want to protect the discount you have earned.
- The add-on premium is reasonable compared with the potential lost discount.
- The policy permits the types and number of claims you may need to make.
Before buying, compare the add-on premium with the value of the discount you want to protect. Also check whether the benefit applies to all eligible claims or only specified claims.

8. Roadside Assistance Cover: Is It Worth Buying?
Roadside assistance (RSA) provides specified support when your vehicle breaks down or experiences another eligible roadside emergency.
Depending on the product, services may include:
- Towing to an eligible garage.
- Battery jump-start assistance.
- Help with a flat tyre.
- Emergency fuel delivery.
- Minor on-the-spot repairs.
- Key retrieval or other specified emergency support.
Service availability, limits and conditions vary by insurer.
Who may benefit from roadside assistance?
RSA may be useful if you commute daily, travel long distances, drive in unfamiliar areas or own a car that is no longer under the manufacturer’s roadside assistance programme.
It may be less useful if you already receive equivalent services from your vehicle manufacturer or another membership plan.
What should you check?
- Whether the service is available 24 hours a day.
- The towing distance and applicable charges.
- The number of service requests permitted.
- Whether fuel, battery and tyre assistance are included.
- Geographic restrictions and response conditions.
- Whether assistance is available after an accident as well as a breakdown.
ACKO lists roadside assistance services that may include towing, flat-tyre help, battery jump-start and fuel support, subject to its product conditions.

9. Tyre Protection Cover: What Should You Know?
Tyre protection is an optional benefit that may cover specified tyre or wheel damage under defined circumstances. The benefit can be relevant because tyre replacement may be expensive, especially for vehicles with larger or specialised tyres.
However, tyre protection does not necessarily cover every puncture, wear-related replacement or tyre failure.
Check whether the policy covers:
- Accidental cuts or bursts.
- Damage to the tyre sidewall.
- Eligible wheel or rim damage.
- Labour or fitting charges.
- The maximum number of claims.
- Exclusions for wear and tear, improper use or pre-existing damage.
Tyre cover is more likely to be worth considering when the vehicle’s tyres are expensive and the add-on’s premium and conditions are reasonable.

10. How Much Do Car Insurance Add-ons Cost?
There is no single price for an add-on across all cars and insurers. The cost depends on the vehicle, its age, the base policy, selected benefits, applicable rating factors and the insurer’s product terms.
| Add-on | What influences the price? | How to assess value |
| Zero depreciation | Vehicle age, model, eligible parts and policy conditions | Compare the extra premium with potential depreciation deductions |
| Engine protection | Vehicle value, covered risks and eligibility | Consider the cost of eligible engine repairs and the risks in your area |
| Return to invoice | Vehicle age, invoice value and policy limits | Compare the premium with the potential IDV-to-invoice difference |
| Consumables cover | Vehicle type, product terms and benefit limits | Review likely eligible repair expenses |
| NCB protection | Current NCB, vehicle and add-on terms | Compare the add-on cost with the discount you could lose |
| Roadside assistance | Service package, vehicle and benefit limits | Compare the cost with equivalent services already available |
| Tyre protection | Tyre type, vehicle and benefit limits | Consider replacement costs and the exclusions |
How to compare prices properly
When requesting quotes, use the same vehicle details and base cover. Then compare the price with and without each add-on.
Ask the insurer or review the quote for the following:
- Individual add-on premium.
- Taxes and other applicable charges.
- Eligibility restrictions.
- Maximum claim limits.
- Deductibles and exclusions.
- Whether the benefit is already included elsewhere.
Do not assume an add-on is good value simply because it is inexpensive. A low-cost benefit with a restrictive limit may be less useful than a slightly more expensive one with clearer, broader protection.

How should you choose between insurers?
Request quotations from the official insurer websites using identical vehicle details, base cover and selected add-ons. Compare the individual add-on premium, maximum benefit, claim limits, exclusions and eligibility restrictions.
Check whether a benefit covers the risk you actually want to manage. For example, zero depreciation will not replace engine protection, and roadside assistance will not pay for every mechanical repair.
The best choice is the policy whose wording, benefits and cost suit your car and driving needs—not necessarily the one with the largest number of add-ons.
12. How Can You Choose the Right Add-ons for Your Car?
Use the following guide as a starting point.
| Your situation | Add-ons to consider | Reason |
| You have a new car | Zero depreciation and possibly return to invoice | May reduce eligible depreciation deductions or the financial gap after total loss |
| You live in a flood-prone area | Engine protection | May cover specified engine damage caused by water ingress |
| You drive long distances regularly | Roadside assistance | Provides specified emergency services during eligible breakdowns |
| You want to reduce eligible repair expenses | Consumables cover | May pay for listed consumables used in covered repairs |
| You have accumulated a high NCB | NCB protection | May preserve the eligible renewal discount under specified conditions |
| Your car has expensive tyres | Tyre protection | May cover specified tyre or wheel damage |
| You have expensive smart keys | Key and lock protection | May reduce eligible replacement costs |
| You already have manufacturer roadside assistance | Review whether separate RSA is needed | Avoid paying twice for overlapping services |
Before buying, check whether the add-on is compatible with your base policy and vehicle. Read the policy wording and ask the insurer about any exclusions that could materially affect a claim.
Frequently Asked Questions
1. Which car insurance add-ons are most useful?
Zero depreciation, engine protection, return to invoice, consumables cover and roadside assistance are common options. Their usefulness depends on your car’s age, repair costs, location, driving habits and existing benefits.
2. Is zero depreciation cover worth buying for an old car?
It depends on the vehicle’s age, the insurer’s eligibility rules and the extra premium. Some insurers restrict zero-depreciation cover to vehicles below a specified age. Compare the premium with the depreciation deductions you could otherwise face.
3. Does engine protection cover flood damage?
It may cover specified engine or gearbox damage caused by water ingress, depending on the add-on wording. It does not automatically cover every flood-related loss or mechanical failure. Check exclusions and follow the insurer’s instructions after water enters the engine.
4. Is return-to-invoice cover the same as zero depreciation?
No. Zero depreciation reduces specified depreciation deductions on eligible parts during repairs. Return-to-invoice cover may provide a benefit linked to the original invoice value after a qualifying theft or total loss. They protect against different financial risks.
5. Do car insurance add-ons increase the premium?
Yes, add-ons generally increase the premium. The amount depends on the vehicle, selected benefit, insurer and policy terms. Compare the individual add-on cost with the protection it provides before buying.
6. Can I buy add-ons when renewing my car insurance?
You may be able to select eligible add-ons when renewing or changing insurers, subject to the product’s rules. The insurer may require an inspection or impose eligibility conditions, particularly if the policy has expired or there is a gap in cover.
Final Summary
Car insurance add-ons help you tailor your policy to specific risks. Zero depreciation can reduce eligible depreciation deductions, engine protection may cover defined engine-related risks, return to invoice can help after qualifying total loss or theft, and consumables cover may reduce certain repair expenses. NCB protection, roadside assistance and tyre protection serve different purposes.
Do not purchase every add-on automatically. Compare the extra premium, benefit limits, exclusions and eligibility rules against your car’s value and usage. Always read the insurer’s current policy wording before making a decision.
