Why should I use a Home or Contents Insurance calculator?

When you take out home and/or contents insurance, it’s important that the amount you’re insured for accurately reflects the cost to rebuild your home and/or replace your belongings. This is because you might have to pay the difference out of your own pocket if you’re insured for less than the replacement value of your home and contents.

In fact, 81% of homeowners and renters are exposed to significant financial loss because their insurance does not cover them to resume the same standard of living in the event of a crisis. 1

The home insurance calculator is designed to estimate the valuation of a residential property and can also be used as a landlord insurance calculator. To get an estimate of how much it would cost to replace your building and/or contents, use our quick and easy calculators below. All you need to do is enter your address and double check that we’ve got your building and contents information right.

How do you calculate the replacement cost of your house?

Your home building estimate will depend on a range of factors, such as your home’s floor area or size, design, quality of materials, and land slope.

Remember to include structures like your pool and granny flat in the calculations; however you will need to exclude your land value.

Frequently Asked Questions

If you already have a home or contents insurance policy with Allianz, upon your annual insurance renewal we will apply an automatic inflation increase for the amount of your home and/or contents that you are insured for (your “sum insured”). Check your insurance premium renewal to view the new increased sum insured.

While we will apply an average inflation amount it is worthwhile to undertake a review of your home or contents value and update your sum insured for any new items purchased or any specified contents. It is important to review your home sum insured as building costs, labour and materials change over time and these costs may differ to average inflation costs.

As you accumulate and upgrade your belongings over time, the cost of replacing your new contents may increase. That’s why it’s important for you to regularly review your contents sum insured to make sure it accurately reflects your contents’ value in the event of a claim.

Rebuilding costs can rise over time, increasing the replacement value of your home. This is especially true if you have undertaken any household renovations, including adding on extensions to your home. When you’re undertaking household renovations, remember to let us know about renovations worth over $75K if you have home insurance or $50K if you have landlord insurance with us.
