It means you didn't have to make any home loan repayments during the deferral period.
It's important to note that, by deferring your repayments, the interest was capitalised. This means that the interest you'd have normally paid during the deferral period continued to accrue and was added to your outstanding home loan balance, to be paid after the deferred period. In turn, your outstanding balance increased, and you'll pay more interest over the life of the loan.
For example, if you borrowed $300,000 with 20 years remaining at 3.5% and you deferred your repayments for six months, you would pay an additional $8,674 in interest and have your loan extended by 13 months. The actual cost to you depends on your own individual circumstances.
When the deferral period ended, to help keep your repayments as similar as possible to what you were previously paying, we extended your loan term as required. Note that if you extended your home loan deferral period, your loan term wasn't extended further, which possibly resulted in a higher monthly repayment amount than what was paid before the deferral.
Taking advantage of a repayment deferral didn't impact your credit rating or appear on your credit file during the deferral period.
