How does total replacement home insurance work?

Total replacement home insurance (sometimes called complete replacement home insurance) works like this: if an insured event like a fire or storm destroys your home, it can cover the cost of rebuilding your property to its previous state.

Most home insurance policies don't do this; with most, you select how much you want to insure your property for (sum insured).

Total replacement cover home insurance policies reduce the gap between the amount your home is insured for and what it actually costs to rebuild the home to its original condition. As a result, they tend to cost more.

The often cheaper alternative is a sum insured safeguard. This is a "safety net" that can provide up to an additional 30% of cover on top of your sum insured if your home is destroyed.

Total replacement cover vs sum insured cover

There are two main types of home insurance available:

  • Total replacement insurance covers the market value of rebuilding your home, so you're unlikely to have any out of pocket expenses.
  • Sum insured cover makes it your responsibility to decide how much your home will cost to rebuild. For example, if you insure your home for $1,000,000 but it ends up costing $1,200,000 to rebuild, you'll be $200,000 out of pocket.

How to calculate the replacement cost of your home

According to the Insurance Council of Australia, 83% of Australian homeowners and renters are underinsured. To make sure you have the right amount of home insurance, there are two main methods for working out the cost:

  • Cost per square metre. This is a basic method and is based on the size of the house and the materials it's made of, so it can't be relied upon to provide an accurate figure.
  • Elemental estimating. This is a much more sophisticated method that takes into account a range of factors, including local wage rates, material costs, the quality of the finishes used, the nature of the building site, how many levels the home has, council approval fees and more.
Online calculators tip
Try to look for an online calculator that takes into account current building and replacement costs to help you reach a more accurate sum insured. This calculator from the Insurance Council of Australia is a great place to start.

Is total replacement home insurance right for me?


  • It greatly reduces the risk of underinsurance.
  • Peace of mind of knowing that you'll be able to afford the rebuilding costs if disaster strikes.
  • You don't need to rely on your own (perhaps limited) knowledge of how much to cover your home for.


  • Total replacement cover is usually more expensive than sum insured cover.
  • It can take longer to receive the funds as the insurer will need to complete an assessment.
  • Many sum insured policies also offer a "safety net" that can provide up to 30% additional cover which may be enough.

Bottom line about total replacement cover

Regardless of whether you choose total replacement or sum insured home insurance, it’s essential that you shop around before you commit to any one policy. By comparing the features and costs of a range of policies, you’ll find the best value for money for your individual circumstances.
