Motor Insurance Add-ons: Which Ones Are Genuinely Worth The Extra Premium?
Buy a car policy online and you’ll be offered eight to twelve add-ons at checkout. Tick them all and a ₹9,000 premium quietly becomes ₹16,000.
Zero Depreciation
Return To Invoice
Engine Protection
The important questions to ask: Are four or five add-ons sufficient to protect you against real, expensive risks? Does the rest mostly protect you or the insurer’s margins?
This guide explains add-ons and helps you determine which ones you need.
Quick View
| Add-on | Typical extra premium* | Who Should Buy |
|---|---|---|
| Zero depreciation | Regulatory pricing structure variable: ₹1,500-5,000/yr | Cars under 5 years |
| Return to invoice | ≈10% extra on OD premium | New cars (first 3 years); cars on loan |
| Engine protection | ₹1,000-3,000/yr | Flood-prone cities; basement parking |
| NCB protection | ₹500-1,000/yr | NCB of 25% or more |
| Roadside assistance | ₹300-800/yr | Highway drivers; ageing cars |
| Key replacement | A few hundred ₹/yr | Smart-key vehicles |
*Indicative for a mid-size private car; varies by insurer, model, city and IDV.
Add-on 1: Zero Depreciation Cover (NIL Dep / Bumper-to-bumper)
Say your bumper and a door panel are replaced after an accident and the bill is ₹60,000. The insurer does not pay it in full. They first cut each part’s age-related loss of value, called depreciation: 50% on plastic and rubber parts and batteries, 30% on fibreglass. The balance, often ₹20,000-25,000, comes from your pocket.
Zero depreciation removes these cuts. The insurer pays the full price of every replaced part; you pay only a small fixed share called the deductible.
Buy if: Car under 5 years; expensive parts
Skip if: Older car whose IDV is already low
Fine print: Claims are usually capped at two per policy year, consumables stay excluded and the add-on is withdrawn after year 5 (a few insurers stretch to 7-8 post-inspection).
Add-on 2: Return to invoice (RTI)
If your car is stolen or damaged beyond repair, the insurer pays only its current market value. It is what the policy calls the IDV, which falls every year. Return to invoice closes the gap: the insurer pays the full original invoice price instead, including road tax and registration in most policies.
THE GAP, IN NUMBERS
Example: You paid ₹12 lakh on-road in 2023. By 2026, the IDV is around ₹8.5-9 lakh. Stolen without RTI: a ₹3 lakh+ hole. With RTI, the settlement matches your invoice.
Buy if: Car under 3 years, on loan, or in theft-prone parking
Skip if: Car 4+ years old (most insurers won’t offer it)
Note: Triggers only on theft or total loss (repair cost crossing ~75% of IDV), never partial damage.
Add-on 3: Engine protection cover
Drive through a flooded street, or let water reach a parked car’s engine and the repair bill can run ₹1-5 lakh. A standard policy refuses this claim: it covers accident damage and engine damage from water or leaking oil is excluded. Engine protection pays for exactly this: repair or replacement of the engine and gearbox.
Buy if: Mumbai, Chennai, Kolkata, low-lying Delhi-NCR; basement parking
Skip if: Dry region with elevated, covered parking
Add-on 4: NCB protection
Skip claims for a year and the insurer rewards you with a discount on the next renewal and that is the No Claim Bonus. It grows every claim-free year, up to half of your own-damage premium (the part covering your own car). File even one small claim and the entire discount resets to zero.
| Claim-free years | 1 | 2 | 3 | 4 | 5+ |
|---|---|---|---|---|---|
| OD discount earned | 20% | 25% | 35% | 45% | 50% |
At 50% NCB on a ₹20,000 OD premium, that record is worth ₹10,000 a year. NCB protection (about ₹500-1,000) preserves the slab through one or two claims a year.
Buy if: NCB at 25% or higher
Skip if: NCB at 0-20%; little to protect yet
Add-on 5: Roadside assistance (RSA)
Car breaks down mid-journey? Roadside assistance sends help, anywhere in India: towing, flat-tyre change, restarting a dead battery, emergency fuel, or unlocking the car if the keys are inside. At ₹300-800 a year, it costs less than one private towing bill (₹2,000-5,000). It is a service request, not a claim and your NCB stays safe.
Buy if: Highway commutes, road trips, ageing car
Skip if: Already bundled free in your plan. Check first
Add-on 6: Key replacement cover
Lose a modern smart key and a local key-maker cannot help. Only the dealership can replace and reprogram it, for ₹10,000-30,000 (more for luxury cars). This add-on pays that bill. For an ordinary metal key that costs a few hundred rupees to cut, it’s a wasted premium.
Buy if: Smart key, keyless entry, luxury car
Skip if: Standard metal key
Add-ons Many Usually Skip
These get pushed hard at checkout. Most private-car buyers can pass:
| Add-on | What It Covers | Why It Rarely Justifies the Cost |
|---|---|---|
| Consumables cover | Engine oil, coolant, nuts and bolts used in repairs | Small amounts; only worth bundling cheaply with zero dep + engine protect in flood cities |
| Passenger PA cover | Personal accident cover for co-passengers | ₹15 lakh owner-driver PA is already mandatory; a standalone PA plan covers the family better |
| Depreciation reimbursement | Refunds depreciation after the claim settles | Zero dep’s outcome with a pay-first process. Compare wordings |
| Tyre protect | Tyre damage outside accidents | Only for low-profile tyres on broken roads; wear is excluded anyway |
| Daily allowance | Commute allowance while the car is in the garage | Capped at modest amounts for limited days |
Driving an EV?
The battery pack is 40-50% of an EV’s value and water damage to it is the EV equivalent of a hydrostatic lock. Insurers now sell battery protect and charger-and-cable covers. Apply the same test: real risk, big bill, fair premium.
Match the Add-ons to Your Situation
| Your situation | A sensible stack |
|---|---|
| Brand-new car in a metro, on loan | Zero dep + RTI + engine protect + RSA |
| 3-7-year-old daily commuter | Zero dep (if offered) + NCB protect + RSA |
| 8-year-old city runabout | Plain comprehensive + RSA; spend the savings on maintenance |
| Luxury or smart-key vehicle | Zero dep + key replacement + consumables (parts priced like jewellery) |

Frequently Asked Questions
Can I buy add-ons in the middle of a policy year?
With most insurers, no. Add-ons attach at purchase or renewal. A few allow mid-term additions after inspection. If the monsoon is closer than your renewal, ask about a mid-term endorsement.
Do add-ons work with a third-party-only policy?
No. Add-ons ride on the own-damage section, so they need a comprehensive or standalone OD policy. With third-party-only cover, upgrading the base policy comes first.
If I switch insurers at renewal, do my add-ons move with me?
Add-ons don’t port. You re-purchase them with the new insurer, though your NCB transfers. Renew before expiry: a lapsed policy can mean re-inspection and the new insurer may refuse zero dep on an older or break-in vehicle.
My car has an extended warranty. Do I still need engine protection?
Yes, they cover different failures. Warranties pay for manufacturing defects and exclude flood, water ingress and accident-linked damage, which is exactly what engine protect handles.
Is there GST on add-on premiums?
Yes, 18%, same as the base premium. The September 2025 GST exemption covered only life and individual health insurance; motor add-ons stayed at 18%.
