What Is an Offset Account and How Does It Work? — Australian Guide 2026

An offset account is a transaction account linked to your home loan. The balance in your offset reduces your loan principal for interest calculation purposes — saving you interest on money you can still access any time.

How It Works

$500,000 loan + $50,000 in offset = interest charged on $450,000

At 6.0% p.a. that saves $3,000/year on money you can access anytime.
