What it does
The IDV (insured declared value) is the most the insurer pays if your car is stolen or written off. It is the ex-showroom price plus accessories, less depreciation for the car’s age. The no-claim bonus (NCB) is a discount for each claim-free year. This tool shows both, and what a repair claim would pay.
Compare a quote’s IDV with the table value, then see whether a small repair is worth claiming with claim or pay for the repair yourself?, or weigh a higher deductible with car insurance deductible chooser.
How to use it
- Enter the ex-showroom price, accessories, purchase date (or the age in months), engine size and claim-free years. The numbers shown are examples: change them to yours.
- Optionally enter the IDV from a quote to see the difference.
- For a claim, list each part with its kind and cost, and the labour charge.
What each setting does
- Purchase date or age in months: sets the depreciation. Typing months overrides the date.
- Engine size: decides the compulsory deductible you pay on every claim.
- Part kind: metal is depreciated by the car’s age; plastic, rubber and nylon 50%; fibreglass 30%; glass not at all.
- Zero-depreciation add-on: the insurer does not take off depreciation on parts.
Worked example
An 8,00,000 car bought 30 months ago: depreciation is 30%, so the IDV is 5,60,000. Three claim-free years give 35% NCB. A 1,200 cc engine has a deductible of 1,000. A metal part costing 20,000 loses 15% at that age: 17,000, plus 5,000 labour, minus the deductible. Over 5 years the IDV is agreed with the insurer.
FAQs
Is a higher IDV better? It pays more at a total loss but costs more premium. Check what it would cost to replace the car.
Is the NCB tied to the car? It belongs to you as the owner and can move to a new car; ask your insurer.
Are my numbers stored? No, nothing leaves this page.
How it’s worked out: IDV = (price + accessories) × (1 − age depreciation); payout = parts × (1 − part depreciation) + labour − compulsory deductible, floored at 0.
Where the numbers come from
- India Motor Tariff GR.8 (IDV depreciation by age), GR.9 (depreciation on parts), GR.27 (no-claim bonus 0, 20, 25, 35, 45, 50%) and GR.40 (compulsory deductible, 1,000 up to 1,500 cc and 2,000 above). Insurers still follow these after detariffing. Checked 2026-11-10, check the official source.
- IRDAI, the insurance regulator, for the general rules on motor own-damage cover.
