How premiums are calculated

Understand some of the factors that are used to calculate insurance premiums.

How is the cost of insurance determined?

The cost of your insurance policy depends on your risk, which in turn reflects the likelihood you will need to make an insurance claim.  The lower your risk, the lower your premium will generally be.

It also depends on the value of what you are insuring, because things with a higher value will generally cost more to repair or replace.

Your premium is also made up of relevant local state and territory government stamp duties and levies, as well as the GST.

How is the price of home insurance calculated?

Some of the key factors which can influence the price of home insurance include:

  • The level of cover you choose – CGU offers three different levels of home insurance cover, at different price points.
  • How your home is occupied and used – using your home as a business, or leaving it unoccupied for long periods can impact cost.
  • Where your home is located – if your home is located in an area with statistically higher theft rates, your risk is higher and so too are your costs. If you are located in an area prone to natural disasters, such as flood, cyclone or bushfires, your risk and consequently insurance price will also increase.
  • What your home is constructed of, and how old it is – age and construction can indicate how likely your home is to structurally withstand damage.
  • The value of your home and contents – the value of your home and contents can influence the cost to replace them in the event of a claim.  It’s important that you have enough insurance to adequately cover the cost of rebuilding and replacing your home and contents – you can use CGU’s online calculators to find out more.

How is the price of car insurance calculated?

Some of the key factors which can influence the price of car insurance include:

  • Your age – young drivers are less experienced and tend to be in more accidents, so are a higher risk which influences premiums. 
  • Where your vehicle is kept overnight – vehicles kept in garages are less likely to be damaged than those parked on the street. 
  • Your suburb or town – the location where you regularly park your vehicle may also be more or less prone to theft.
  • Your driving history – if you have a good driving history, where you haven’t had any claims made against you, your risk is lower and your premium will be as well.
  • The make and model of your car – your car’s age and type influences what the cost to repair or replace your vehicle will be.
