The IDV depreciation chart shows how a vehicle's Insured Declared Value (IDV) decreases with age, directly affecting insurance premiums and the amount payable in the event of a total loss or theft claim. For businesses that own or manage vehicles, understanding depreciation is important for maintaining adequate insurance coverage, estimating financial exposure and making informed fleet replacement decisions.
IDV is calculated using the following formula:
IDV = Manufacturer's Listed Selling Price – Depreciation
The depreciation percentage applied depends on the vehicle's age and is determined using a standard depreciation schedule.
What does the IDV chart show?
The IDV depreciation chart shows the percentage by which a vehicle's value is reduced for insurance purposes based on its age. Insurers use these depreciation rates to calculate the vehicle's IDV, which is used for total-loss and theft claim settlements.

Market value assessment or mutual agreement between the insurer and the insured |
For vehicles older than five years, insurers generally determine IDV based on the vehicle's condition, market value and mutual agreement with the policyholder.
For example, suppose a business purchases a delivery vehicle with an ex-showroom price of ₹12 lakh.

Note: These figures are illustrative and assume no additional accessories, market-value adjustments or insurer-specific IDV variations. Actual IDV may vary based on vehicle condition, declared accessories and insurer assessment.
The example shows how IDV decreases as a vehicle ages. After five years, the IDV falls from ₹12 lakh to ₹6 lakh. If the vehicle is stolen or declared a total loss, the claim amount may be significantly lower than the original purchase price.
IDV also affects insurance premiums. A higher IDV generally results in a higher own-damage premium. In comparison, a lower IDV reduces both the premium and the compensation available in the event of a total loss or theft.
However, IDV is only one factor affecting premiums. Vehicle type, geographical location, claim history, No Claim Bonus (NCB), add-on covers and insurer underwriting practices can also influence the final premium payable.
Fleet example: Calculating business impact
Consider a logistics company operating two delivery vehicles that originally cost ₹15 lakh each.

Vehicle A |

₹12.75 lakh |
|
Vehicle B |
4 years |
40% |
₹9 lakh |
Now assume both vehicles suffer a total loss in separate incidents.
- Potential claim payout for Vehicle A: approximately ₹12.75 lakh
- Potential claim payout for Vehicle B: approximately ₹9 lakh
The business would receive ₹3.75 lakh less for the older vehicle.
This difference can materially affect replacement decisions. If purchasing a replacement vehicle costs ₹15 lakh, the company would need to arrange only ₹2.25 lakh in additional funds after Vehicle A's claim settlement, compared with ₹6 lakh after Vehicle B's settlement.
Constructive total loss and IDV
IDV is used to determine whether a vehicle qualifies as a Constructive Total Loss (CTL). Under standard industry practice, a vehicle may be treated as a CTL if the aggregate cost of retrieval and repairs exceeds 75% of its IDV. In such cases, the insurer may settle the claim as a total-loss claim, subject to the policy terms.
How can businesses use the IDV chart effectively?
Businesses can use the IDV chart to assess how insurance protection changes as vehicles age and estimate the amount available under a total-loss or theft claim.
The chart also helps businesses evaluate whether older vehicles continue to provide adequate financial protection. For example, a business may find that vehicles approaching five years of age have experienced a significant reduction in insured value despite remaining operationally critical. This may support decisions on vehicle replacement or fleet upgrades.
Businesses can also use the chart to assess the trade-off between lower premiums and lower claim payouts. While a lower IDV may reduce insurance costs, it can also increase out-of-pocket expenses if a vehicle is stolen or declared a total loss.
When reviewed across an entire fleet, the IDV chart helps businesses track changes in insured asset values and plan insurance budgets, replacement schedules and capital expenditure more effectively.
Conclusion
The IDV depreciation chart is more than an insurance calculation. It helps businesses understand how claim payouts change as vehicles age, evaluate whether existing coverage remains adequate and make informed decisions about fleet replacement and insurance costs. Regularly reviewing IDV across vehicles can help reduce the risk of underinsurance and improve financial planning.
For businesses managing multiple vehicles, maintaining accurate records of assets, insurance policies and replacement schedules is equally important. TallyPrime helps businesses organise this information in one place, making it easier to track assets, monitor insurance-related data and support better fleet and financial management decisions.
