A home loan is likely to be the biggest expense you will ever have. While the home itself will cost several hundred thousand dollars at least, the interest component of that loan could easily add another couple of hundred thousand dollars. The average home loan can last 25-30 years, which is a long time to pay something off. The longer you have the loan for, the more you’ll have to pay.

But what if there was a way to reduce the length of your home loan, and save on interest? By making an extra lump sum payment off your loan, you can.

Any extra repayment you make - be it lump sum repayments or recurring repayments above the minimum - can save you money simply because it reduces the principal on the loan, aka the borrowed amount left to repay. Interest is charged on this principle amount, so the smaller the principal, the less there is to charge interest on.

Also the more you repay, the quicker you’ll pay off the loan. Our home loan extra repayment & lump sum payment calculator can show you just how much difference extra repayments can make to your overall loan.

All you have to do with our extra repayment/lump sum calculator is:

  • Enter the loan amount and the loan term (the length of the loan)
  • Enter your loan’s interest rate
  • Enter your repayment frequency
  • Enter how much your extra lump sum payment will be, or how much extra you’ll be paying per month
  • Specify how far into the loan schedule you’ll make these extra repayments

Let’s say you have a 25-year, $400,000 home loan at a 3.50% interest rate. Using our lump sum repayment calculator, you can estimate that a $25,000 one-off payment into your home loan could shave 21 months and $17,500 off your home loan.

Using our extra repayment calculator, if you started paying an extra $200 a month into that same home loan, you could save more than 4 years and $38,000.

So if you’ve received some extra cash lately (like a work bonus or an inheritance) or just want to get ahead of your loan, then use our extra repayment and lump sum calculator to see how much you could save by using that money to pay down your mortgage.
