The right amount of cover is so important.

For most of us, our home is an incredibly valuable asset, so we need to make sure we have the right cover in place to protect it. Without the right amount of cover in place, you run the risk of being unable to rebuild your home to a similar size or standard.

The Cordell Sum Sure calculator can help by estimating your "Sum Insured" amount. This amount is how much you will need to rebuild your home in the event of a total loss, and includes things like the cost of removing debris or rebuilding special features; these are easy to miss when you’re thinking about the true cost of rebuilding.

Your Sum Insured amount includes

  • Your home - the actual building
  • Fencing, decks, patios
  • Garages and/or sleepout
  • Swimming pool
  • Driveway
  • Professional fees
  • Recreational features (spa pools, water features)
  • Special features (bridges, culverts, landings, jetties)
  • Built-in Barbeque(s)
  • Retaining walls
  • Gazebos
  • Demolition and debris removal
  • Compliance costs
  • Garden Sheds

How the calculator works

The Cordell Sum Sure calculator works by using construction industry data from around New Zealand as well as individual property data from councils and a range of other sources.

In most cases, all you need to do is enter an address, confirm your property details and make any updates. Then you'll be provided with an estimate to rebuild your home.

Options to calculate your Sum Insured

The calculator is easy to use but remember, it is just an estimate. You can consult a professional such as a registered builder or valuer for the most accurate valuation.
