Home loan offset calculator
See what your offset balance, plus a regular monthly deposit, really does to your loan: the interest saved, the years cut off your term, and the month your loan stops charging interest altogether.
Tip: salary credited to the offset and everyday bills paid from it count as deposits too. Even the days money rests there save interest.
Your loan balance, with and without the offset
The gap between the two lines is money staying in your pocket. From the dot onward, your offset covers the whole remaining balance and the loan accrues no interest at all.
Estimate only. Assumes a constant interest rate, repayments held at the standard principal-and-interest amount, and deposits continuing monthly. Package fees on offset products are not included. Results are not a quote, loan offer or pre-approval.
Why the regular deposit matters more than the balance
Every dollar in an offset account cancels interest on a dollar of your loan, at your full loan rate, tax free. A lump sum helps, but a growing balance compounds: each monthly deposit saves interest every month for the rest of the loan, and because your repayment stays the same, all of that saved interest quietly attacks the principal instead.
That is why $1,000 a month into the offset routinely beats much larger one-off contributions over a full loan term, and why households that credit their salary to the offset and run daily spending from it finish years early without feeling any change in lifestyle.
The catch: not every loan has a genuine 100% offset, and packaged offset products often carry annual fees. Whether an offset beats a lower-rate loan with redraw depends on your average balance, which is a five-minute check with Nathan.
