A premium is an amount that is paid for insurance cover. The amount is paid up front and represents is calculated based on the exposure or risk that you have added to the system.
Generally there are a few indicators that gets looked at when determining the premium:
1) The value of the item
The more valuable the item is the more premium should be paid by the consumer to add the risk to the system as it will ultimate cost the system more to replace or repair the item
2) How risky is the item?
This is generally split into 2 aspects.
a) The frequency in which the item is used and hence claims are expected
For example mobile phones are used more often (daily use) then cameras (weekly use). This results in a higher risk of being damaged or stolen and results in a higher premium.
b) The severity of a claim when something goes wrong.
For example if someone crashes their drone the odds are high that the entire item will be completely destroyed.. When someone drops a camera it is likely that the entire item will not be destroyed, but can be repaired. Hence the camera should attract a lower premium.
Electronics are also more fragile than tables for example and attract a higher premium as they are more likely to be damaged.
3) How risky is the environment where the item is in?
When determining the premium we also take a look at the environment.
a) Who is the owner?
If the owner has had claims in the last few years the odds of the owner having claims are higher and the item attracts a higher premium
b) Where is the owner based?
If the owner resides in an area with high crime rates the item is a lot more likely to be stolen and should attract a higher premium.
c) For what purposes is the item used?
If the item is used for commercial purposes it will be used a lot more than someone who uses it as a hobby. This should attract a higher premium as the odds of damage or theft will be higher.
