Is a home loan repayment calculator accurate?
Yes, if you enter accurate details like the loan amount, interest rate, and term. The tool uses real lender formulas to give you a reliable estimate. Always use the comparison rate for better accuracy. Remember, results are indicative but very close to real figures.
Can I use the calculator for investment loans?
Yes, it works for both owner-occupied and investment loans. Just make sure to use the correct interest rate and term. Investment loans may have higher rates, so adjust accordingly. The results give a solid repayment estimate either way.


Can I calculate repayments for an interest-only loan?
Yes, most calculators offer an interest-only option. This shows lower repayments during the interest-only period. Once the interest-only term ends, higher principal repayments apply. It's useful to see both phases and plan ahead.
