IDV in Car Insurance: What It Means and How to Check If You're Underinsured
IDV (Insured Declared Value) is all your insurer will pay if your car is stolen or totalled. Most Indians are underinsured by 20–30% because of how IDV is calculated and manipulated. Here's the formula, the IRDAI depreciation schedule, and how to check yours.
What is IDV?
IDV (Insured Declared Value) is the maximum amount your insurer will pay you if your car is declared a total loss — either stolen and not recovered, or damaged beyond economic repair (typically when repair costs exceed 75% of IDV).
It is NOT the market value of your car. It is the depreciated ex-showroom value.
The Red Alert: If your car's IDV is set at ₹6 lakh but the actual replacement cost is ₹8 lakh, you lose ₹2 lakh the moment your car is stolen. This is your "Uninsured Loss."
The Official IRDAI Depreciation Schedule
Insurers are legally required to calculate IDV based on this schedule for cars up to 5 years old:
| Car Age | Depreciation Applied |
|---|---|
| Up to 6 months | 5% |
| 6 months to 1 year | 15% |
| 1 year to 2 years | 20% |
| 2 years to 3 years | 30% |
| 3 years to 4 years | 40% |
| 4 years to 5 years | 50% |
| Beyond 5 years | Mutually agreed (typically market value) |
The IDV Calculation Formula
IDV = (Manufacturer's Listed Selling Price − Depreciation) + (Accessories − Depreciation)
Note: Registration costs and insurance premiums are NOT included in IDV. This is why even a brand new car's IDV is 5% lower than its ex-showroom price on day one.
Why Your IDV Might Be "Rigged"
When you compare car insurance online, the portal usually asks you to choose an IDV. Some insurers pre-select a lower IDV to show you a cheaper premium.
The Agent Strategy: An agent might show you a "savings" of ₹2,000 on your premium by reducing your IDV from ₹7 lakh to ₹6 lakh. You "save" ₹2,000 but you "lose" ₹1,00,000 in coverage.
How to Check if You are Underinsured
- 1Get your car's original ex-showroom price (check old bills or brand websites).
- 2Apply the depreciation percentage from the table above based on your car's age.
- 3If the number on your Policy Schedule is lower than your result, you are underinsured.
Example: The 3-Year Old Swift
- Original Ex-Showroom: ₹9,00,000
- Age: 3 years (Depreciation: 40%)
- Correct IDV: ₹5,40,000
- If your policy shows ₹4,80,000 — you are losing ₹60,000 in coverage to save maybe ₹800 in premium.
Does IDV Matter for Normal Repairs?
For "Partial Loss" (scratches, dents, engine repair), IDV does not matter. The insurer pays the repair cost. IDV only matters for:
- 1Total Theft
- 2Total Loss/Constructive Total Loss (CTL): When repair cost > 75% of IDV.
Pro Tip: IDV for Cars Older than 5 Years
For older cars, IDV is "mutually agreed." Insurers often try to set it very low (e.g., ₹1 lakh for a 7-year old Honda City). You can and should negotiate this. Check used car prices on platforms like Spinny or Cars24 and insist on an IDV that matches the market price.

Conclusion
Check your policy today. Look for "Insured Declared Value." If it feels too low, call your insurer and ask for an endorsement to increase it. The extra premium is usually less than the cost of a single tank of petrol.
