Are there limits on extra repayments?

Variable rate loans typically have no limits on extra repayments. Fixed rate loans usually allow $10,000-$20,000 per year in extra repayments without penalty. Check your loan terms for specifics.

Should I pay extra or put money in an offset account?

Both achieve similar interest savings, but offset accounts offer more flexibility - you can access the funds if needed. Extra repayments into the loan can only be accessed via redraw (if available).

What's better - lump sum or regular extra payments?

A lump sum saves more interest overall because it reduces principal immediately. However, regular extra payments are more sustainable for most budgets and still save significant amounts.

Can I reduce my loan term instead of my repayments?

Yes! Many lenders let you keep the same repayment after rate drops, which acts as an extra payment. Or you can formally restructure to a shorter term for bigger savings.
