IDV Explained with Calculation Examples
Definition
Insured Declared Value (IDV) is the maximum sum insured under a motor insurance policy, representing the current market value of the vehicle. It is calculated as the manufacturer's listed selling price of the vehicle (plus any accessories) minus depreciation based on the age of the vehicle, as per IRDAI-prescribed depreciation rates. IDV is the maximum amount the insurer will pay in case of total loss or theft of the vehicle.
Explanation in Simple Language
IDV is the cornerstone of motor OD insurance. It determines: (1) the premium you pay — higher IDV means higher premium; (2) the maximum payout in case of total loss or theft; and (3) the basis for under-insurance or over-insurance arguments.
IRDAI prescribes a depreciation schedule for calculating IDV based on the vehicle age:
- Not exceeding 6 months: 5% depreciation
- Exceeding 6 months but not exceeding 1 year: 15%
- Exceeding 1 year but not exceeding 2 years: 20%
- Exceeding 2 years but not exceeding 3 years: 30%
- Exceeding 3 years but not exceeding 4 years: 40%
- Exceeding 4 years but not exceeding 5 years: 50%
For vehicles older than 5 years, IDV is determined by mutual agreement between the insurer and the insured, based on a surveyor's assessment or prevailing market value. IRDAI allows a flexibility of ±10% on the calculated IDV, giving insurers and policyholders some room for negotiation.
Real-Life Indian Example
Vikram purchased a Tata Nexon XZ+ (Petrol) in January 2022 for ₹12,50,000 (ex-showroom). In January 2025, when renewing his motor insurance, the vehicle is 3 years old. Using IRDAI depreciation rates: IDV = ₹12,50,000 - 30% depreciation = ₹12,50,000 - ₹3,75,000 = ₹8,75,000. He also has an aftermarket music system worth ₹25,000 (2 years old, depreciated at 20%) adding ₹20,000. Total IDV: ₹8,95,000. His insurer offered an IDV of ₹8,50,000 (within the -10% range). Vikram negotiated and settled at ₹8,80,000, paying a slightly higher premium for better coverage.
Numerical Example
Detailed IDV Calculation:
Vehicle: Maruti Suzuki Swift ZXi (2021 model)
Ex-showroom Price: ₹8,40,000
Age at Renewal (2025): 4 years
Depreciation Rate: 40%
Base IDV = ₹8,40,000 × (1 - 0.40) = ₹8,40,000 × 0.60 = ₹5,04,000
Accessories:
- Factory-fitted alloy wheels: Included in ex-showroom price (no separate calculation)
- Aftermarket CNG kit: ₹65,000 (3 years old, 30% depreciation)
CNG IDV = ₹65,000 × 0.70 = ₹45,500
Total IDV = ₹5,04,000 + ₹45,500 = ₹5,49,500
IRDAI allows ±10%:
- Minimum IDV: ₹5,49,500 × 0.90 = ₹4,94,550
- Maximum IDV: ₹5,49,500 × 1.10 = ₹6,04,450
Impact on Premium (OD rate assumed at 2.8%):
- At Minimum IDV: OD Premium = ₹4,94,550 × 2.8% = ₹13,847
- At Maximum IDV: OD Premium = ₹6,04,450 × 2.8% = ₹16,925
- Difference: ₹3,078 per year
Policy Clause Reference
IRDAI Guidelines on IDV:
1. Clause 1 of the Indian Motor Tariff (now de-tariffed for OD): IDV shall be deemed to be the sum insured and shall be treated as the market value of the vehicle.
2. For new vehicles (less than 6 months old): IDV = Invoice value minus registration and insurance costs.
3. For vehicles 5+ years old: IDV to be determined mutually between insurer and insured based on a physical inspection or an agreed valuation.
4. Accessories fitted to the vehicle but not part of the manufacturer's listed selling price must be valued separately.
5. Bi-fuel kits (CNG/LPG) must be declared and their IDV added to the base vehicle IDV.

Claim Scenario
Scenario: Deepika's 2020 Hyundai i20 (ex-showroom ₹9,80,000) was stolen from a shopping mall parking lot in Noida in 2024. The vehicle was 4 years old. Her policy IDV was set at ₹5,88,000 (40% depreciation applied). She had chosen the minimum IDV range to save on premium.
Claim Process:
1. FIR filed immediately with Noida Police (Sector 18 PS).
2. Insurer informed within 24 hours.
3. Non-traceable certificate obtained from police after 90 days.
4. Surveyor verified documents — RC, policy, FIR, keys submitted.
5. Claim settled at IDV value: ₹5,88,000.
Deepika was disappointed — the prevailing market value for her car was approximately ₹6,50,000. Had she opted for a higher IDV (within the +10% range), her payout could have been ₹6,46,800. The ₹58,800 difference would have cost her only about ₹1,650 more in annual premium.
Common Rejection Reason
1. Over-Insurance — If the IDV is set significantly above market value, the insurer may dispute the valuation during a total loss claim and apply the principle of indemnity to pay only actual market value.
2. Non-Declaration of Accessories — Aftermarket accessories not declared in the policy are excluded from the IDV and will not be compensated.
3. Salvage Disputes — In theft claims, if the vehicle is recovered after settlement, the insured must return the claim amount or surrender the vehicle to the insurer. Disputes arise when the recovered vehicle is damaged.
4. Pre-Inspection Lapse — For policies issued without pre-inspection (break-in cases), the insurer may question whether the vehicle was in proper condition at policy inception.
Legal / Arbitration Angle
The principle of indemnity governs IDV disputes. The Supreme Court in United India Insurance Co. Ltd. v. Leela Mahadev Khandare (2010) clarified that IDV is the agreed value under the policy and the insurer is bound to pay the IDV amount in case of total loss or theft, unless fraud is proven.
However, in cases where IDV is deliberately inflated, courts have upheld the insurer's right to pay only the actual market value, treating the excess as over-insurance under Section 32 of the Marine Insurance Act (applied by analogy).
The Insurance Ombudsman frequently handles IDV disputes, particularly where insurers unilaterally reduce IDV at the time of claim settlement despite having accepted premium on a higher IDV.
Court Case Reference
Key Case: New India Assurance Co. Ltd. v. Pradeep Kumar (2009) — The Supreme Court held that IDV mentioned in the policy schedule is the agreed value and the insurer cannot renegotiate it downward at the time of claim settlement. The insurer had accepted premium based on the declared IDV and was estopped from disputing it.
Common Sales Mistakes
1. Defaulting to the lowest IDV to show a cheaper premium quote — this harms the customer in total loss/theft claims.
2. Not explaining what IDV means — most customers do not understand that IDV is their maximum payout.
3. Forgetting to add CNG/LPG kit value to IDV — this leads to claim rejection for the kit.
4. For vehicles older than 5 years, not arranging a proper inspection leads to IDV disputes later.
5. Not informing the customer about the ±10% flexibility — customers should know they have a choice.
Claims Dispute Example
Dispute: Ramesh had a 2018 Honda Amaze with IDV set at ₹4,20,000. The car was totalled in a highway accident. The insurer offered ₹3,85,000 citing that the pre-accident market value was lower. Ramesh argued that the IDV in the policy is the agreed value.
Ombudsman Ruling: The Ombudsman ruled in Ramesh's favour, directing the insurer to pay the full IDV of ₹4,20,000. The ruling stated that once the insurer accepts premium based on a declared IDV, it becomes the agreed value and cannot be unilaterally reduced at the time of claim unless fraud is established.
Learning for POSP / Advisor
POSP Guidelines on IDV:
1. Educate clients that IDV = Maximum payout. A lower IDV saves ₹1,000-₹2,000 on premium but can cost lakhs in a total loss claim.
2. For new cars (under 2 years), always recommend IDV at the higher end of the IRDAI range — the premium difference is minimal.
3. For older vehicles (4-5 years), carefully calculate IDV as it significantly impacts settlement.
4. Always declare accessories — CNG kits, music systems, alloy wheels. Undeclared accessories will not be compensated.
5. For vehicles older than 5 years, insist on a proper physical inspection to set a fair IDV.
6. Use this pitch: "Would you accept ₹5 Lakhs if your ₹8 Lakh car is stolen? For just ₹1,500 more per year, you can insure it closer to the real market value."
Summary Notes
IDV (Insured Declared Value) is the maximum claim payout under motor OD insurance. It is calculated as the ex-showroom price minus age-based depreciation (IRDAI schedule: 5% to 50% for 0-5 years). For vehicles older than 5 years, IDV is mutually agreed. IRDAI allows ±10% flexibility on calculated IDV. Aftermarket accessories must be declared separately. Lower IDV saves premium but reduces payout. Always advise customers to choose IDV close to actual market value. In disputes, the IDV mentioned in the policy is treated as the agreed value by courts and ombudsman.
Case Study Questions
Q1.A customer insists on choosing the lowest IDV to minimize premium. His car is worth ₹7 Lakhs in the market but the lowest permissible IDV is ₹5.4 Lakhs. If the car is stolen, what is the financial impact? How should you advise him?
Q2.A 6-year-old vehicle needs insurance renewal. The insurer refuses to offer more than ₹2.5 Lakhs IDV but the owner believes the car is worth ₹4 Lakhs. What are the owner's options under IRDAI guidelines?
