Home Loan Repayment Calculator

There’s no single right answer, because it depends on your interest rate, your goals and how comfortable you are with risk. Paying down your loan gives you a guaranteed, tax-free return equal to your interest rate and reduces your debt, which many people value for the certainty. Investing may offer higher returns over the long run, but those returns aren’t guaranteed and come with ups and downs along the way. Plenty of people do some of each, and the right balance is worth talking through against your own numbers rather than a general rule.

Yes, extra repayments reduce both the interest you pay and the time it takes to clear the loan. Interest is charged on your outstanding balance, so paying the loan down faster means less interest builds up over the years. Extra repayments early in the loan make the biggest difference, because that’s when the balance, and the interest on it, is highest. It’s worth checking that your loan allows extra repayments without penalty, which most variable loans do.

Both reduce the interest you pay, so the right choice comes down to how much access you want to your money. Money in an offset account is set against your loan balance for interest purposes but stays available to withdraw whenever you need it, which suits people who want a buffer they can reach. Extra repayments also lower the balance interest is charged on, though getting the money back usually means redrawing, if your loan allows it. For many people an offset offers similar interest savings with easier access, but the fees and features of your particular loan matter, so it’s worth comparing them.

Even a small rate rise can lift repayments noticeably, especially on larger loans. Because interest applies to your whole balance, a move of half a per cent or a full per cent adds up quickly. The clearest way to see the effect is to enter your loan amount and term, then adjust the rate up and down to compare the repayments. Testing a rate higher than the one you’ve been quoted also shows whether you’d still be comfortable if rates climbed.

It comes down to the balance between repayment size and total interest. A shorter term means higher repayments but less interest over the life of the loan, because you clear it faster. A longer term lowers each repayment and helps with cash flow, but you pay more interest overall. A common approach is to pick a term that keeps repayments comfortable, then make extra repayments when you can to shorten it in practice.
