About comparison rates. When a lender advertises an interest rate on a fixed-term personal loan, the ad must also show a comparison rate, which folds in most fees. It's worked out for an example loan and is only accurate for that example. The rate with fees above does the same for your amount and term. Neither counts fees that only apply in some cases, such as early repayment fees.

How it works

Headline rates can mislead: a loan with a lower rate can cost more once its fees are counted. Put in up to three loans and this works out what each would cost you in total.

  1. 1Enter the loan amount you need
  2. 2Select your preferred loan term
  3. 3Input the interest rate and fees for Loan 1
  4. 4Input the interest rate and fees for Loan 2
  5. 5See which loan is truly cheaper overall

Questions people ask

What is a comparison rate?
The comparison rate includes both the interest rate and most fees associated with the loan, expressed as a single percentage. It gives you a more accurate picture of the true cost. In Australia, lenders must display comparison rates alongside advertised rates.
Which fees should I consider when comparing loans?
Look at establishment/application fees (upfront), monthly account-keeping fees (ongoing), and early repayment fees. Some lenders offer 'no fee' loans but charge higher interest rates to compensate.

The terms, in plain English

Establishment Fee
A one-time upfront fee charged when you take out a loan. Also called application fee or setup fee. Can range from $0 to $500+.
Ongoing Fees
Monthly or annual fees charged throughout the loan term. Even small monthly fees add up - $10/month = $600 over 5 years.
True Cost
The total amount you pay over the life of the loan including principal, interest, and all fees.
