When will these Big Four Bank personal loan calculators come in use?

When you decide to get a personal loan it is best that you know how much you’ll have to repay each week, fortnight or month, and this is where a calculator can help. While such a calculator can help you compare crucial features of the loan, it comes with other benefits as well.

  • Establish the effect of your interest rate. Even a relatively small difference in your rate can lead to a significant difference in how much you end up paying throughout the course of your loan, and this becomes clear when you use a calculator.
  • See how a changing loan term can help you save. Changing the loan term has two effects, and you can find out about both through a loan calculator. While increasing the loan term reduces repayment size, you end up paying more in the form of interest. Reducing the loan term means your repayments will be higher, but you're likely to pay less interest in the long run.
  • Save money. Given that loan calculators help you compare different types of loans, you can find out which one saves you the most.
  • Choose loan type as per your budget. By changing the parameters of your loan — repayment terms, loan type, type of interest — you can find a loan that will work best for your budget.
  • Save time. Since such calculators require you to select and enter basic details, and then do the calculations for you, they can help you save time while you decide what loan to apply for.

Personal loan calculator offers two distinct calculators for people who’re thinking about getting personal loans. The loan repayment calculator requires you to enter loan amount, loan term, interest rate and repayment frequency. Using this information you can see your repayments over the term of your loan.

The loan comparison calculator, on the other hand, allows you to compare any two loans, which can include loans offered by the Big Four Banks. In addition to entering a common loan term and loan amount, other values you can enter include upfront fees, ongoing fees, any introductory rate and term, and ongoing rates.
