Borrowing power calculator

Indicative starting-point estimate only. This calculator uses the income, expenses and loan assumptions you enter. It does not apply the full postcode, household expense, rental income or credit policies of a lender. Actual borrowing capacity may differ. This is not loan approval or pre-approval.

Includes HELP, VET Student Loans and other study and training loans. The compulsory repayment comes out of this applicant's pay.

The repayment is never more than the balance. Leave it blank if the balance is more than a year's repayment.

Includes HELP, VET Student Loans and other study and training loans. The compulsory repayment comes out of this applicant's pay.

The repayment is never more than the balance. Leave it blank if the balance is more than a year's repayment.

An HtAG assumption, not a lender's figure. Change it if your lender uses another.

Include car and personal loans, ongoing rent or board after the purchase, and child support. Exclude mortgages and credit cards entered separately. Count each cost once.

Your household's monthly living costs, including dependants. Exclude mortgages, credit cards and other monthly commitments entered separately.

Lender benchmarks can depend on income, dependants and location. HtAG does not calculate HEM; enter a current figure from your broker. Leave blank to use your declared living costs without a lender benchmark.

Rental assumptions (optional)
Rental assumptions (optional)

Total running costs across these rentals, excluding interest and loan repayments. Leave blank for the covered allowance. Only costs above 20% of gross rent are deducted again; this allowance is separate from the rent percentage below.

The rental-purpose part of the existing loan balances entered above, not their repayments. Exclude private borrowing and the new purchase loan. Leave blank to apply no existing rental-interest offset.

Leave blank for 80% in the standard case and 75% in the conservative case. Enter a percentage to use it in both cases; the conservative case still increases living costs by 10%. Zero counts no rent. Maximum 80%.

How it’s calculated

The method behind your estimate

How this estimate works

Use household income, declared living costs, existing debts and loan assumptions to explore a starting-point borrowing range. Review assessment-rate and rental-tax assumptions.

What to check before you act

This is not a lender credit assessment or approval. Lenders use their own expense benchmarks, postcode policies, buffers and investment-income treatment.

Why can a lender give a different result?

Lenders assess income, expenses, debts and security differently. Postcode-dependent benchmarks and verified documents can change capacity.

Is HELP included?

The supported model includes compulsory study-loan repayments where applicable. Check the inputs and the rules date against your circumstances.

Is the borrowing power calculator free to use?

Yes. Every HtAG calculator is free to use with your own figures, and you do not need an account. An HtAG plan adds property and suburb data to the calculators that support it.
