Why use the personal loan borrowing calculator?
This calculator gives you a good estimate of how much you could afford to borrow for a personal loan. You’ll also get an estimate of the interest rate and repayment amount you could expect. It only takes a minute. Just pick your preferred personal loan, enter your income, expenses and what you think your credit rating might be. The personal loan borrowing calculator does the rest.
How much can I borrow for a personal loan?
Your estimate repayments are calculated based on the loan type, loan amount, loan term and your credit score entered. The calculations do not include upfront or continuing credit fees and charges. Lending is to approved applicants only. All lending is subject to a detailed credit assessment, the results from this calculator do not constitute a loan application or variation to an existing facility, loan offer or loan approval.
Your contracted personal loan repayments will be set to a monthly frequency, meaning you will need to meet the agreed repayment amount by the due date stated on your loan contract each month. To meet this minimum monthly amount, you can however make repayments weekly or fortnightly.
This calculator provides general information only and should not be relied on to make a decision about a financial product. You should consider obtaining advice from an appropriately licensed financial services professional before making any financial decisions.

A personalised interest rate is determined in large part by your credit score. This is based on a range of factors including your history of repaying loans, credit cards, and other bills. In short, the better your credit score, the lower the interest rate you’re likely to be offered.
Speaking of which, it's worth noting that while submitting a full application will likely result in a small, temporary dip to your credit score, simply getting your estimated personalised rate will not impact it.
It certainly can’t hurt to check your credit report before applying as doing so won’t affect your credit score. Having said that, some credit reporting agencies have a limit on the number of free checks you can make within a certain period of time.
An easier solution might be simply to get your estimated personalised rate from us. It won’t impact your credit score either, only takes about a minute, and you’ll know what to expect in terms of repayments without going through the full application process.
