Fortnightly home loan repayment calculator

By making a fortnightly payment instead of a monthly one, you can save a tonne in mortgage interest and own your home sooner. Here's how.

Key takeaways

  • By switching to fortnightly payments from monthly payments you'll end up making an extra monthly payment each year.
  • This would mean you'll pay your home loan off faster and pay less interest over that time.
  • You should check how your lender calculates its new payments though. If they divide your annual repayments into fortnightly repayments, you won't actually save any money.

How to use the fortnightly repayment calculator

To use the fortnightly repayment calculator you just need a few of your home loan details:

  • Loan term: Select the number of years you took out the home loan for.
  • Original loan amount: Enter the amount you borrowed for your home loan.
  • Interest rate: Enter your current interest rate.
  • Made repayments: Work out the number of monthly repayments you've already made. Note this is in months and not years.

You'll then see the calculations comparing monthly repayments, fortnightly repayments and weekly repayments.

The term bi-monthly in the calculator refers to your monthly repayment being split in half and then charged every 2 weeks. This is different to some fortnightly repayments where the cost is calculated from your annual repayment, which we explain below.

Expert insight: Be aware of lender calculations

"Some banks will allow you to change your repayment frequency, but they'll take your monthly repayment multiplied by 12 months and divided by 52 weeks. Then they'll multiply this by two for [lower] fortnightly payments.

Some lenders by nature will calculate it their own way and there's no two ways about it. But some lenders will calculate a true fortnightly repayment."

How banks calculate fortnightly repayments

There are 2 ways banks will calculate your fortnightly repayments and one of those ways doesn't save you money at all.

Option 1 - Bi-monthly fortnightly repayment: Your lender splits your monthly repayment in half. You repay that amount every 2 weeks. Because there are 26 repayments in a year and not 24, you'll make an additional month's repayment over the year.

Option 2 - Annual fortnightly repayment: Your lender will take your annual repayment and divide it by 26 for the number of repayments you'd make that year. This means your fortnightly repayments will be lower, but you'll repay the same amount annually as you would have if you kept your monthly repayment.

How fortnightly repayments can save you money

Let's take a look at how a $600,000 home loan on an interest rate of 5% over 30 years would fare with each repayment method:

Monthly repayment

Your monthly repayments would be $3,220.93. That's an annual repayment of $38,651.16. You'd pay a total of $1,159,534.71 over the 30 year loan.

Bi-monthly fortnightly repayment

You'll be paying $1,610.46 a fortnight. This means you make an annual repayment of $41,871.96. That's an extra $3,220.80 a year (a whole extra month's repayment) which will cut your home loan by 4 years and 6 months. You'll save more than $80,000 in interest.

Annual fortnightly repayment

Your fortnightly repayment would be a lower repayment of $1,486.52. You'd pay the same amount annually as if you'd kept your repayment monthly. Therefore you'd save no time or interest on your loan.

What to be aware of with fortnightly home loan repayments

Although fortnightly home loan repayments should save you money over the long run, there are a couple of reasons they might not work for you.

  • Your pay cycle. If you get paid monthly you might find it easier to pay your home loan monthly too, rather than making sure you have the right amount of money in the right account when your home loan repayments are due. This doesn't mean you can't benefit in the same way as someone making fortnightly repayments. If you put aside the money and your loan allows extra repayments, simply pay an additional month's repayment into your loan each year. Or more if you can spare it!
  • Mortgage stress. Paying fortnightly means you make an extra month's repayment each year. That's because months (mostly) aren't exactly 4 weeks. When you pay every fortnight there are 2 months of the year which have an extra repayment. You need to make sure you have the budget flexibility for those months. If you're struggling with your home loan repayments as it is, having that extra repayment twice a year can make things much harder.

    Just in regards to this. What if you had an offset account set up and you were able to place those fortnightly repayments into the account anyway for the repayments to then be taken out monthly ?

      Hey Daniel!

      Thanks for the question.

      The effect of fortnightly or bi-monthly repayments is to add an extra monthly repayment towards your home loan each year, so a similar effect might be able to be obtained by depositing similar extra amounts into an offset account. You might want to go through the sums with a mortgage broker, accountant or with your lender to find out exactly how it’ll affect your loan term.

      I hope this helps,
      Marc.

    Should I be paying a fixed loan differently? Currently it is being paid weekly.

      Hi Denise,

      Thank you for contacting finder.com.au, a financial comparison website.

      Each individual’s specific circumstances and needs are different and they should pay off their loan in a way that suits them, you can use the calculator on this page to see how changing the repayment frequency of your loan will affect your circumstances.

      If you want further advice I would recommend speaking to a mortgage broker, financial advisor or your lender directly.

      Regards
      Jodie
