Why use this calculator

Frequently Asked Questions

What does this loan calculator show?

It shows your regular repayment, how much interest you pay over the life of the loan, the total repaid, and a year-by-year breakdown of how the balance falls.

Why does paying fortnightly or weekly change the total?

More frequent repayments reduce the outstanding balance sooner, so slightly less interest builds up. The effect is usually small but real.

Does this include fees?

No. It covers principal and interest only. Application fees, ongoing account fees and insurance are not included.

Can I use it for a mortgage or car loan?

Yes. Any fixed-rate, fixed-term loan that is repaid in equal instalments works the same way, whether it is a mortgage, car loan or personal loan.
