FAQs

Good to know

What costs are involved in refinancing?

Typically a discharge fee from your current lender plus government fees — often $500-$1,000 total. Cashback offers frequently exceed these costs entirely.

How do I find out my current interest rate?

Check your loan statement, banking app, or ask your lender. A surprising number of people are shocked by the answer — rates drift up quietly over time.

When is refinancing not worth it?

When savings are tiny, your loan is nearly paid off, break costs on a fixed rate outweigh gains, or your circumstances have changed in ways that limit options. We'll tell you honestly either way.

Can I refinance and keep my repayments the same?

Yes — and it's a powerful strategy. Keep paying your old repayment at a lower rate, and the difference attacks your principal directly, shortening the loan.
