The 75% Rule That Decides If Your Insurer Repairs or Writes Off Your Bike
The 75% damage-to-IDV rule that decides whether your insurer repairs your bike or writes it off entirely.
Co-Founder · Letsbima.com

A "total loss" and a "constructive total loss" sound like the same outcome — your bike gets written off — but they arrive there through very different routes. One means the vehicle is physically destroyed or unrecoverable. The other means it is technically repairable, but the insurer has decided repairing it makes no financial sense.

01Total Loss vs Constructive Total Loss
A Total Loss (TL) applies when the vehicle is destroyed beyond any physical recovery — fire, a severe collision, or confirmed, unrecovered theft. A Constructive Total Loss (CTL) applies when the vehicle could physically be repaired, but the estimated repair cost crosses a threshold that makes repair uneconomical relative to the vehicle’s declared value.
02The 75% Repair-Cost-to-IDV Rule
Most insurers classify a claim as a Constructive Total Loss once the estimated repair cost — parts plus labour — crosses roughly 75% of the vehicle’s Insured Declared Value (IDV). At that point, repairing the vehicle costs the insurer nearly as much as, or more than, simply settling it as a write-off.
IDV: ₹90,000 | Estimated repair cost after assessment: ₹72,000 (80% of IDV)
03Why Your Declared IDV Decides Everything
IDV is fixed at policy issuance, based on the manufacturer’s listed price minus a fixed, age-based depreciation schedule. Choosing a deliberately lower IDV shaves a small amount off your premium — but it also hard-caps your total-loss and theft payout. This trade-off is easy to miss when a "lower premium" option looks attractive at renewal without checking what it costs on the downside.
Before You Accept a Discounted IDV
- A 10% lower IDV can mean a ₹9,000+ shortfall on a ₹90,000 bike if it is ever stolen or totalled.
- Always cross-check the quoted IDV against your bike’s realistic on-road resale value, not just the insurer’s default figure.
- IDV auto-depreciates every year at renewal whether or not you notice — review it deliberately, don’t let it default.
04The Surveyor's Role & How to Contest a Low IDV
An independent surveyor appointed by the insurer inspects the vehicle and prepares the repair-cost estimate that determines TL, CTL, or a standard repair claim. If you disagree with the assessed damage or the IDV applied, you can request a re-survey or an independent assessment. If the dispute remains unresolved, you can escalate through the insurer’s grievance redressal officer, and subsequently to IRDAI’s Bima Bharosa portal.
