How accurate is the borrowing power estimator on this page?

It is purely mathematical: monthly surplus after expenses and commitments, applied at the assessment interest rate and loan term you enter. It does not include lender-specific serviceability floors, household benchmarks, HECS, dependants, credit scoring, or how each bank applies regulatory buffers. Use it as a rough guide only.

Are Azure Home Loans mortgage calculators accurate for my actual loan?

These tools show mathematical estimates from the numbers you enter. They do not replace a lender credit assessment, product fees, offset accounts, or your full living expenses. Use results for orientation, then confirm with a broker or lender.

Does the repayment calculator include interest-only or offset accounts?

The repayment calculator models standard principal and interest amortising loans. Interest-only and offset structures change outcomes; speak with a broker for a product-accurate repayment picture.

How does the refinance savings calculator treat switching costs?

It compares monthly repayments at two rates with the same balance and remaining term, then divides one-off switching costs by the monthly saving to show a simple break-even in months. It does not model cashback vesting, break fees on fixed loans, or loan term extensions.

Why does the stamp duty section link to government websites?

Transfer duty rules, concessions and surcharges differ by state and territory and change with budgets. Official revenue office calculators stay aligned with current law, which a generic site cannot replicate reliably.

What does the buyer-cost planning buffer represent?

It is an illustrative percentage of purchase price to help you mentally reserve funds beyond the deposit for legal work, inspections, registrations, moving and a post-settlement buffer. It is not stamp duty and not a quote of your total funds to complete.

Can extra repayment results differ from my bank app?

Yes. The extra repayment model assumes a constant add-on to scheduled principal and interest, with no fees or redraw behaviour. Fixed-rate loans may cap extra repayments; variable loans may behave differently with offsets. Check your loan contract.

How does the offset calculator treat my balance?

It estimates interest not charged on an amount equal to your offset balance at the stated nominal rate — as if that balance fully reduced the balance interest accrues on. It does not replicate daily sweep timing, partial offsets, package discounts, or how your lender applies repayments.

Is the split loan repayment accurate if my fixed and variable portions have different terms?

No. The split tool blends two nominal rates by percentage of balance and amortises the full amount as one P&I loan. Real split loans often have different reset dates and repricing behaviour — use it only as a rough blended repayment illustration.

Is the Reserve Bank cash rate the same thing as my home loan rate?

No. The RBA cash rate target influences funding conditions banks face, but your loan rate reflects lender pricing sheets, borrower risk tiers, margins, and features — it will not automatically match the headline cash rate announcement. Refer to public materials at rba.gov.au for the cash rate target timeline.

Do these calculators replicate lender serviceability assessments?

No. Formal assessments include policy floors, benchmarks, buffers, liabilities, residency, postcode overlays, valuation haircuts and more — see APRA housing lending supervisory material for institutional context — but your calculator numbers are illustrative only.

General information only. These calculators provide estimates based on the numbers you enter. They do not constitute credit advice, take your full situation into account, or replace a lender's assessment. Fees, eligibility, and actual offers vary. Speak with a broker for guidance tailored to you.

Repayment calculator

Estimate principal & interest (P&I) repayments for a standard amortising loan at a constant nominal rate. Switching to fortnightly or weekly uses the standard Australian lender approach of paying half (or a quarter) of the monthly figure each period — which genuinely shortens the loan and saves interest. The numbers below model that saving; they do not model offset, redraw, fees, or rate changes.

Loan amount

The amount you intend to borrow after deposit.

Loan term at this frequency: 30 yrs
Total repayments: $1,308,949
Total interest (estimate): $708,949

Modelled from the scheduled monthly repayment of $3,636. Real-world results vary with daily-accrued interest, offset and redraw behaviour, lender fees and rate changes — confirm against your loan contract.

A summary of your loan

Side-by-side at the same loan, rate and starting term — the saving comes purely from paying more often.

Repayment plan	Repayment	Total interest	Total repayments	Loan term
Monthly repaymentsselected	$3,636 / month	$708,949	$1,308,949	30 yrs
Fortnightly repayments	$1,818 / fortnight	$554,848	$1,154,848	24 yrs 6 mo
Weekly repayments	$909 / week	$554,172	$1,154,172	24 yrs 5 mo

Modelling assumption: fortnightly repayment = monthly ÷ 2, weekly repayment = monthly ÷ 4. Both result in roughly 13 monthly-equivalent repayments per year instead of 12 — which is where the term reduction and interest saving come from.

Comparison rate calculator

ASIC-method · regulated reference

Two home loans with the same advertised rate can cost very different amounts once you add fees. The comparison rate folds the interest rate together with mandatory upfront, ongoing and discharge fees into one APR-style number — calculated under ASIC Regulatory Guide 234. Below you can model both your own scenario AND the regulated $150,000 over 25 years reference loan that every advertised comparison rate uses.

On the same fee structure, smaller loans amortise fewer dollars across each fixed-dollar fee, so the comparison rate is typically higher on the $150k reference than on your larger loan. That's why a $1M loan can "feel cheaper" than an advertised comparison rate suggests.

How to read a comparison rate

A bigger gap = more fees. A 0.30%+ gap between headline and comparison usually signals an annual package fee or hefty upfront costs.
It assumes you keep the loan to term. If you refinance after 3 years, the upfront fees hurt more than the comparison rate suggests.
Loan size matters. Bigger loans dilute fixed- dollar fees, so your comparison rate is usually better than the advertised one.
It excludes third-party fees (LMI, government stamp duty), offset benefits, redraw and break costs — those need a broker review.

Interest-only vs principal & interest

Compare a simplified interest-only monthly instalment with a standard P&I repayment on the same balance and rate — and see what happens after the IO period ends. Real IO periods are time-limited (usually 1–5 years for owner-occupiers, up to 10 for some investor products) and policies vary.

Split loan — blended rate repayment

If you split the balance between a fixed and variable portion, a reasonable first pass is to blend the two nominal rates by weight, then amortise the full balance as one P&I loan. Reality adds separate ledgers, end dates, and repricing — use this as orientation only.

Extra repayment impact

See how adding a consistent extra amount above your scheduled P&I repayment shortens the loan and reduces modelled total interest — holding the headline rate and mandatory instalment constant. Many fixed-rate products cap voluntary extra repayments; variable loans may pair better with offset redraw logic that this tool does not simulate.

Purchase costs & stamp duty

We link to each state and territory's official transfer duty (stamp duty) tools because rules, concessions, surcharges and dutiable value treatments differ — a single generic estimate cannot stay accurate across jurisdictions or budget changes.

Choose where you are buying and use that jurisdiction's calculator for a duty figure. Then layer legal fees, registration, inspections and your post-settlement buffer with your conveyancer and broker.

Calculators are maintained by the relevant revenue office or official provider — not by this website.
