What do extra home loan repayments save you?

Interest at your loan rate on every extra dollar, for every month it stays in the loan. Even small amounts take years off a 30-year loan, and the calculator shows the interest saved and the time cut on your numbers.

On a fixed loan, check the cap on extra repayments first; an offset gives the same saving with the money still accessible. Other ways to pay off a home loan faster are in our guide.

Charles at Links Property Finance made buying our first home so much easier than we expected. As first home buyers, we had a lot of questions around borrowing capacity, our deposit and the different government schemes available to us. Charles explained everything clearly, compared different lenders and kept us updated throughout the whole process. He was always easy to reach and made sure we understood what was happening from pre approval right through to getting our home loan approved. We would definitely recommend Links Property Finance to anyone looking for a mortgage broker, especially first home buyers who want someone to guide them through the process.

Common questions about extra repayment

Do extra repayments shorten the loan?

Yes. Anything above the minimum reduces the balance that interest is charged on, and over a long loan the compounding effect on both interest and term is substantial.

Is an offset account better than paying extra directly?

Neither is better in general: they save interest similarly, but an offset keeps the money accessible, while extra repayments may sit behind a redraw facility with its own rules.

Can I make extra repayments on a fixed rate?

Usually only up to a capped amount per year before break costs enter the picture, and the cap varies by lender. Check the loan terms before setting up a large recurring extra payment.

How can I pay off my mortgage in 10 years?

Work out the repayment that would clear your balance in 10 years at your current rate, then compare it with what you pay now.

The calculator on this page shows how much each extra dollar a month cuts from the term. Pairing higher repayments with an offset account and a sharper rate is usually what makes a 10-year target realistic.

What is the fastest way to pay off a mortgage?

Pay more than the minimum as often as you can: extra monthly amounts, fortnightly repayments, and lump sums such as tax refunds or bonuses. Keep your savings in an offset account, and check your rate is still competitive, because a lower rate sends more of every repayment to the balance.
