Significance Importance of IDV
As stated earlier, IDV is the maximum amount for which the insurer is liable in case of your bike being stolen, or in case of a total loss. Total loss simply means that the expenses that would be incurred to restore the two wheeler to a road-ready condition are significantly high compared to the value of the two wheeler. Typically, the insurer would write the bike off as a total loss if the cost of repair is higher than 75% of the IDV.
While the exact IDV of the bike is determined based on the formula provided by the IRDAI, you would get a leeway to change it by 15% in either direction. The higher the IDV, the higher would be the premium you will have to pay. If the higher IDV was mutually agreed upon between the insurer and the insured, you would get the higher amount as compensation in case of a total loss/theft. That said, you should not increase the IDV unreasonably as then you would be paying an additional premium for no additional value.
You should not revise the IDV down just to lower the premiums. For one, this would mean you will not get enough compensation in case of a theft or total loss and will have to shell out a higher amount from your pocket to get a replacement. Additionally, if the insurer determines that the IDV is but a fraction of the bike’s value all the claims will be honoured in the same proportions. For example, if you set the IDV as ₹75,000 even when the formula determines it to be ₹1 lakh. All your claims would be honoured only up to 75%, and you will have to pay the remaining 25% out of pocket, even though the expense is covered by your two wheeler insurance policy.
