1. What is IDV?
Insured Declared Value (IDV) is the current market value of your vehicle — the maximum amount your insurer will pay if your vehicle is stolen or declared a total loss. It's essentially the sum insured for your car or bike under a comprehensive policy.
IDV is not arbitrary — it's calculated using a standard formula prescribed by IRDAI:
IDV = Ex-showroom price × (1 − Depreciation %)
Depreciation depends on vehicle age, but condition and city can also influence the final negotiated IDV.
2. The IRDAI depreciation schedule
The insurance regulator prescribes depreciation rates based on how long you've owned the vehicle:
| Vehicle age | Depreciation % | IDV (% of showroom) |
|---|---|---|
| 0–6 months | 5% | 95% |
| 6 months – 1 year | 15% | 85% |
| 1 – 2 years | 20% | 80% |
| 2 – 3 years | 30% | 70% |
| 3 – 4 years | 40% | 60% |
| 4 – 5 years | 50% | 50% |
| Above 5 years | Negotiated | Varies |
For vehicles older than 5 years, IDV is negotiated between the insurer and the policyholder. Most insurers rely on the "India Motor Tariff" or their own depreciation tables to arrive at a fair value.
3. How IDV affects your premium
IDV is the base for the own-damage (OD) premium:
OD premium ≈ IDV × OD rate × (1 − NCB) + Add-ons
A higher IDV means:
- Higher premium — because the base value is larger.
- Higher claim on total loss — you get more if the vehicle is written off.
For a car with a ₹10L IDV at 3% OD rate, a 10% higher IDV (₹11L) would increase the OD premium by about 10% — roughly ₹3,000. That ₹3,000 buys you ₹1L of extra protection on a total loss. For most buyers, it's worth it.
4. How IDV affects your claim
IDV is the maximum the insurer will pay for total loss or theft. But for partial damage, the claim is based on actual repair cost (subject to depreciation on parts, unless zero-dep add-on is chosen).
Scenario: Your car is stolen. Its IDV is ₹8L.
- If you chose IDV of ₹8L, you get ₹8L (minus any deductions).
- If you under-insured at ₹6L, you get only ₹6L — a ₹2L shortfall.
- If you over-insured at ₹10L, you still only get ₹8L — the insurer won't pay more than the market value.
So over-insuring wastes premium (you pay more but don't get more). Under-insuring saves premium but exposes you to a real shortfall. The right IDV is the fair market value of your vehicle.
⚠️ Under-insuring your vehicle to save premium is a false economy — you risk a large shortfall on a total-loss claim when you need it most.
5. Can you negotiate IDV?
Yes — IDV is somewhat negotiable, especially for older vehicles. Insurers typically offer a range (say, ±10% of the standard depreciation-based value). You can:
- Ask for a higher IDV if your vehicle is in excellent condition and has low kilometres.
- Accept a lower IDV if you want to reduce premium and are willing to accept a smaller claim.
Most insurers will allow slight adjustments within reason. But you can't set IDV above the fair market value — that would violate the principle of indemnity (you can't profit from insurance).
6. Condition & city adjustments
Two factors that can affect the IDV you're offered:
Condition: A well-maintained vehicle (full service history, low km, no accidents) can be valued 5%–10% higher than a similar-age vehicle with average condition. Conversely, poorly-maintained vehicles may be valued lower.
City: Resale markets vary. Metros usually have slightly higher resale values for popular models, which can translate to a slightly higher IDV. This is a smaller factor than age or condition.
7. A worked example
Take a car with an ex-showroom price of ₹10L, now 3 years old, in excellent condition, in a metro:
| Step | Value |
|---|---|
| Ex-showroom price | ₹10,00,000 |
| Standard depreciation (3–4 years) | −40% |
| Base IDV | ₹6,00,000 |
| Condition adjustment (+5%) | +₹30,000 |
| City adjustment (+2%) | +₹12,000 |
| Final IDV | ₹6,42,000 |
The insurer's standard IDV would be ₹6L. With condition and city adjustments, the negotiated IDV is ₹6.42L. That ₹42,000 extra is what you'd get on a total loss claim.
8. Common mistakes
- Accepting the lowest IDV to save premium. Small premium savings, big claim shortfall.
- Over-insuring to "maximise" claim. Insurers cap at market value — you just waste premium.
- Ignoring depreciation. Every year, IDV drops. Review at renewal.
- Not negotiating. For excellent-condition vehicles, you can often get 5%–10% more IDV.
- Choosing IDV without considering add-ons. Zero depreciation add-on affects the effective claim — IDV is only the max.
- Forgetting that IDV affects future renewals. A higher IDV today means a higher base for next year's depreciation.
9. When to change IDV
Consider adjusting your IDV:
- At every renewal — vehicle age increases, so IDV falls automatically.
- After major repairs — if you've restored the vehicle, you may justify a higher IDV.
- If you've added accessories — these are usually covered separately, but may justify a modest IDV increase.
- If you plan to sell soon — a slightly higher IDV doesn't hurt, but the market price is what matters.
10. Final thoughts
IDV is the anchor of your comprehensive car or bike insurance. It determines both the premium you pay and the maximum payout you receive. Choosing the right IDV — not the lowest, not the highest, but the fair market value — is one of the most important decisions at every renewal.
Use this calculator to find the standard IRDAI-based IDV, then consider whether a condition or city adjustment applies to your vehicle. If in doubt, ask your insurer for a slightly higher IDV — the small extra premium usually delivers more value on a claim.
