What does sum insured mean?

Understanding sum insured

Sum insured is the amount agreed upon by you, the policyholder, and the insurer at the time of purchasing the home insurance policy.

While the sum insured is generally the maximum amount an insurance company will pay you for the replacement of your property and/or contents, after an insured event occurs there are some benefits that may be paid for on top of that amount. It’s important to read your policy documents, such as this Product Disclosure Statement if you have RACV Home Insurance, for clarification.

How sum insured is calculated

To calculate the sum insured, you must evaluate the value of the property or assets being insured and include GST. For home insurance, this typically includes the cost to completely rebuild your home, including factors such as the size, materials, and location. For contents insurance this means the cost to repair or replace things you keep inside your home, including furniture and rugs, fridges, washing machines and TVs. If you need help, to obtain an estimate, you can use the RACV building calculator or contents calculator.^ 

It’s important to take the time to estimate the sum insured. Underinsuring can leave you financially vulnerable, while overinsuring may result in unnecessarily high premiums. Seeking professional advice or using online calculators can assist in providing a more accurate estimate.

When the sum insured is inadequate, you could suffer significant financial loss if your home is destroyed. For example, if a home cost $600,000 to rebuild after a fire but your Home Insurance Policy included a sum insured of $500,000, you could be $100,000 out of pocket if the house has been destroyed.

Common misconceptions

There are some common misconceptions about the sum insured. Some people confuse it with the market value of the property, which includes land value; however, it refers to the cost to replace or repair the property.

There is also confusion around how to factor in inflation, and future costs of housing materials and labour. You should check the product disclosure statement of your home insurance policy to find out if sum insured automatically adjusts for inflation. For example, if you have RACV Home and Contents Insurance, the product disclosure statement states that each year your policy renews, there is an automatic increase in your buildings sum insured and general contents sum insured to account for inflationary trends.

Factors to consider

Several factors need to be considered when determining the appropriate sum insured for your home. Firstly, you must assess the replacement cost of your property, including the main structure and any additional structures like garages or sheds. Consider the materials used, the property's size, and any unique features that might affect the cost. For example, do you have solar power or a solar battery,?

Another vital factor is the value of your personal belongings. Calculate the cost of replacing all your furniture, appliances, electronics, and other possessions. Don’t forget high-value items such as jewellery or artwork.

Avoiding underinsurance

It's crucial to avoid underinsurance, which occurs when the sum insured is less than the actual replacement value. In such cases, you may receive only a partial payout, leaving you to cover the remaining costs yourself. To prevent this, regularly review and update your sum insured to reflect any changes in your property or the value of your belongings.

When and why to review your sum insured

Life changes, and so do the values of our belongings. Failing to review your sum insured could result in being underinsured or overpaying for coverage you don’t need.

So, when should you review your sum insured? It's a good idea to do so whenever you make significant changes to your property, such as renovations, purchasing new items, or selling off belongings. Additionally, it's recommended to review your sum insured annually to account for inflation and any changes in building and labour costs.

How to adjust your sum insured

Adjusting your sum insured is a straightforward process. Start by taking an inventory of your assets, including their values. You can use online tools or consult with a professional valuer to determine accurate replacement costs. Once you have this information, you can contact your insurance provider to update your sum insured accordingly.

Impact of changes on your premium

Keep in mind that adjusting your sum insured can have an impact on your premium. Increasing your sum insured may result in higher premiums, while decreasing it could potentially lead to savings. It's essential to balance the coverage you need with what you can afford.

Remember, it is crucial to regularly review and adjust your sum insured to help cover your assets in an insured event.
