Which Car Insurance Add-Ons Are Worth Buying and Which Are a Waste of Money

Every renewal comes with a menu of optional covers, usually presented as a bundle with a tick already in most of the boxes. A few of them genuinely protect you. Several are cheap enough that the question barely matters. And some are priced well above the risk they cover. Knowing the difference is worth a few thousand rupees a year.

Two things apply across the whole list. Add-ons attach only to a comprehensive or standalone own damage policy, never to a third party only policy, because they all modify how your own car is settled. And they generally cannot be bought mid-term, so renewal is your one window each year to add, drop or change them. That makes it worth actually reading the list rather than accepting whatever your car insurance quote is pre-selected for you.

Zero Depreciation: Worth It on a Newer Car

This is the one that matters most, and the one most often bundled without explanation.

A standard policy deducts depreciation on every replaced part, at 50 percent for plastic, rubber, tyres and batteries, and by the age of the car for metal panels. Zero depreciation waives that deduction. On a repair involving bumpers, lamps and cladding, all of which are plastic on a modern car, it is routinely the difference between recovering most of the bill and recovering half of it.

It typically adds 15 to 20 percent to your own damage premium. Most insurers offer it only up to five years from registration, some to seven. Buy it while your car is young and parts are expensive; drop it when the car is old enough that a claim would be modest anyway.

Engine Protection: Worth It in the Wrong Postcode

The base policy specifically excludes consequential damage, which means if water enters the engine and you try to restart it, the resulting damage is not covered. Nor is engine damage from a lubricating oil or coolant leak. Engine protection covers exactly these, along with damage to the gearbox and differential.

For a car parked in a basement in Mumbai, or driven through Chennai or Bengaluru in the monsoon, this is not a theoretical risk and a hydrostatic lock repair runs well into six figures. For a car in a dry, well-drained area that never sees standing water, it is a reasonable skip. Geography decides this one, not the car.

Consumables: Cheap Enough to Say Yes

Engine oil, coolant, brake fluid, AC gas, nuts, bolts, washers, grease. The base policy excludes all of it, so these items appear on the repair bill and get struck off the claim. On a moderate repair they add a few thousand rupees.

The add-on usually costs a few hundred rupees a year, so a single claim tends to repay several years of premium. One thing to check: some bumper-to-bumper packages already bundle consumables, and buying it separately on top is paying twice.

Return to Invoice: Worth It Early, Then Drop It

If your car is stolen or written off, you are paid the Insured Declared Value, which is the depreciated market value. Return to invoice pays the original invoice price instead, along with registration charges and road tax.

In the first two or three years the gap between invoice price and IDV is at its widest, often one to three lakh rupees, and the add-on is clearly worth its cost. By year four or five that gap has narrowed considerably while the premium has not, and most insurers stop offering it anyway. This is an add-on with a natural expiry date, and the mistake is paying for it out of habit past the point it earns anything.

NCB Protection: Situational

Your No Claim Bonus climbs from 20 percent after one claim-free year to 50 percent after five, and a single claim wipes it back to zero. NCB protection lets you claim once or twice without losing the discount.

At 20 or 25 percent accumulated, the discount is small and the add-on is not worth much. Once you are sitting at 45 or 50 percent, the discount is worth real money and protecting it starts to make sense. Check how many claims it permits and whether it protects the full slab or steps you down one level.

Roadside Assistance: Cheap, But Check for Duplication

Towing, jump starts, flat tyre help, emergency fuel, minor on-site repairs. Bought as an add-on it usually costs a few hundred rupees a year, which is a fraction of what a single unplanned tow costs.

The catch is that you may already have it. Many manufacturers include roadside assistance free for the first few years of ownership, and some credit cards and motoring memberships include it too. Check the towing distance limit as well, since a cover that stops at 50 kilometres is of limited use on a highway. Worth having, not worth paying for twice.

Key Replacement: Usually Skip

Losing keys is genuinely expensive now. A modern smart key with an immobiliser chip, plus reprogramming, can run from ₹8,000 to ₹25,000 depending on the car.

The add-on is cheap, at a few hundred rupees a year, but the maths still favours self-insuring. Most people go many years without losing a key, and over five years of premiums you have paid a meaningful share of one replacement against a fairly low probability of needing it. If it comes free in a bundle, take it. If it is a separate line item, the money is better kept.

Tyre Protection: Usually Skip

The base policy pays for tyres only if the car itself is damaged in the same incident, and even then only half the replacement cost. Tyre protection covers bulges, cuts and blowouts on their own.

It sounds appealing given Indian road conditions, but it is one of the more expensive small add-ons and it excludes ordinary wear, which is what actually finishes most tyres. Unless you routinely drive on genuinely bad roads, this is one to leave.

Daily Cash Allowance: Usually Skip

India does not generally provide a courtesy car. What is offered instead is a fixed daily allowance, often a few hundred rupees, for each day your car is in the workshop, usually capped at ten or fifteen days.

The total payout is therefore small, frequently less than the cost of the add-on across a few years. If you have no alternative transport and a long repair would genuinely disrupt your life, it has some value. For most people, the cap makes it marginal.

Passenger and Driver Cover: Cheap and Often Overlooked

Your policy already includes compulsory personal accident cover of ₹15 lakh for the owner-driver. That is mandatory and you are paying for it whether you notice or not.

What it does not cover is anyone else in the car. Passenger cover and cover for a paid driver are inexpensive extensions and worth adding if you regularly carry family or employ a driver. This is the one add-on on the list where people are usually underinsured rather than oversold.

Glass Cover: Understand What You Are Actually Buying

Here is where a common assumption is wrong. Glass carries nil depreciation under the standard policy already, so a zero depreciation add-on adds nothing at all for your windscreen.

The real benefit of a separate glass cover is different: it lets you claim for glass without losing your No Claim Bonus, which on a windscreen replacement can otherwise cost you more than the glass. That matters more than it used to, because a windscreen on a car with driver assistance features needs the cameras behind it recalibrated after fitting, which can double the bill. If your car has lane keeping or adaptive cruise, check whether recalibration is included.

If You Drive an Electric Car

The standard add-on menu was designed around petrol and diesel cars and maps poorly onto an EV. The battery is the single most expensive component in the vehicle, charging cables and home chargers are not part of the car and are not automatically covered, and water ingression risk applies to the battery pack rather than an engine. Electric car insurance products increasingly offer specific battery protection and charger cover for this reason. If you drive an EV, work through those options rather than assuming an engine protection add-on does anything useful for you.

The Simple Test

Before agreeing to any add-on, ask two questions. Do I already have this, through the manufacturer, another policy, or a package I have already bought? And could I absorb this cost myself without it hurting?

If the answer to either is yes, skip it. Add-ons are worth buying where the loss would be large and the cover is cheap, which is why zero depreciation and engine protection earn their place and key or tyre cover generally does not. And review the list every year rather than rolling forward last year's bundle, because the right set on a one-year-old car is not the right set on a six-year-old one.
