Premium Calculator for Cargo Insurance Costs

Last updated on October 2nd, 2020

Not surprisingly, one of the most common questions we get is: what is the cost of cargo insurance? The calculation isn’t difficult, but you do need to get your valuation right on the goods being insured. The cargo insurance premium on a single shipment is typically calculated as the insured value times the policy rate.

And what is insured value? The simplest method to calculate insured value is to add the commercial invoice value of the goods to the cost of freight and add ten percent to cover additional expense. It is important to review the terms of your insurance policy, specifically the valuation clause, to be certain of how the policy expects the goods to be valued.

It is important that the correct insured value is selected when insuring your cargo. Selecting an amount that is less than the value of the goods, or underinsuring the shipment, can have dire financial consequences. You may be familiar with the term Coinsurance from medical coverage where it is quite common. Coinsurance is the amount in claim that the cargo owner has chosen not to insure – this amount is essentially covered by the cargo owner after the deductible has been paid and before the insurance company pays.

Coinsurance typically expressed as a percentage. In a policy with twenty percent coinsurance, the  insurance company will pay eighty percent of the loss, and the insured will pay the remaining twenty percent. In a cargo policy, coinsurance comes into play when a shipment is underinsured.

For underinsured shipments, in a partial loss, the insurance company will only pay the proportion of the value that has been insured. In the event of a total loss on an  underinsured shipment, different policies may respond with different payment amounts, but the cargo owner will not be made whole. Selecting the right insured value will remove the coinsurance clause from the equation and make sure that the cargo owner is made whole after a loss.
