Compulsory vs Voluntary Deductible: How Much You Pay on a Claim

A deductible (also called excess) is the part of each own-damage claim you pay yourself. Indian motor policies have two kinds.

Compulsory deductible

Applied to every own-damage claim, regardless of what you choose:

An insurer may impose a higher compulsory deductible on vehicles it considers higher risk; it must be shown on your policy schedule. It does not reduce your premium.

Voluntary deductible

An optional extra amount per claim, on top of the compulsory one. In return, you get a discount on the own-damage premium. The India Motor Tariff reference slabs, still used in many insurer prospectuses, are:

How deductibles change a claim

A car up to 1500cc with a ₹5,000 voluntary deductible has a ₹20,000 repair (no parts depreciation, for simplicity). The insurer pays ₹20,000 − ₹1,000 − ₹5,000 = ₹14,000. Without the voluntary deductible it would pay ₹19,000.

Is a voluntary deductible worth it?

Compare the yearly saving with the expected extra cost. For a car with ₹9,000 of own-damage premium before discount, a ₹7,500 deductible saves ₹2,000 (₹2,360 with GST). If you expect to claim once every seven years (about a 15% chance a year), the expected extra cost is ₹1,125 a year — so the deductible comes out ahead on average. If you claim every other year, it doesn’t.

The discount caps mean higher deductibles add risk faster than savings. And because deductibles also push small claims below the point where claiming makes sense, they work best for careful drivers who would pay small repairs themselves anyway.

A two-wheeler example

A bike with an own-damage premium of ₹1,200 before discount chooses a ₹1,000 voluntary deductible. The 15% discount would be ₹180, but it is capped at ₹125 (about ₹148 with GST). On a ₹6,000 repair claim (ignoring parts depreciation), the insurer pays ₹4,900 instead of ₹5,900. The deductible only pays off if the chance of a claim in a year is below roughly 15%.

Deductibles on theft and total loss

Deductibles shown on the schedule generally apply to each own-damage claim, including theft and total loss, unless the policy says otherwise. On a total loss the compulsory deductible is a small share of the payout, but a large voluntary deductible would also be subtracted.

How deductibles interact with NCB

A deductible makes small claims less attractive because it shrinks the payout, while losing NCB costs the same. In practice, owners with a voluntary deductible end up paying more small repairs themselves — which is fine if that was the plan, and an unpleasant surprise if it wasn’t.
