How to read your borrowing power result (and what to do next)

You have run our [borrowing capacity calculator](/calculators/borrowing-capacity) and it gave you a number. Before you start browsing listings at exactly that price, it is worth understanding what the number is, what it is not, and how to turn it into something a lender will actually stand behind.
What the number represents
A borrowing power result is an estimate of the largest loan a typical lender might approve, based on the income, expenses and debts you entered. Behind the scenes it mirrors what lenders do: it converts your gross income to net, deducts living expenses and commitments, applies a serviceability buffer of around 3 percentage points above the assumed rate, and solves for the loan size where the surplus runs out. It is a genuine model of the process — but it runs on unverified inputs and generalised policy, so treat it as a well-lit ballpark, not a promise.
What it is not
The result is not pre-approval, not an offer of credit, and not a guarantee that any specific lender will lend that amount. Three things separate a calculator from a real assessment:
- Verification — a lender checks payslips, statements and your credit file; a calculator believes whatever you type.
- Policy detail — real lenders shade overtime and bonuses, treat HECS and credit card limits precisely, and apply their own expense benchmarks. Calculators generalise.
- Credit decisioning — approvals also weigh your credit history, employment stability, the property itself and your deposit, none of which a borrowing calculator sees.

What pushes the number up
If your result feels low, these are the levers that genuinely move it:
- Reducing credit card limits — limits are assessed as if fully drawn, so cutting a $20,000 unused limit can add meaningfully to capacity.
- Clearing small debts — paying out a car or personal loan removes its whole repayment from the equation.
- Adding a second applicant — a partner's income (net of their expenses and debts) usually lifts the combined result.
- Counting all eligible income — rental income, consistent overtime or bonuses, and some government benefits may count, at least partially, depending on the lender.
- Lender selection — the calculator shows one generalised answer; actual lenders differ, sometimes materially, on the same inputs.
What pushes it down
Equally, the real assessment can come in under your calculator result if:
- Your declared expenses are below the lender's benchmark (HEM) — the lender will use the higher figure.
- Variable income gets shaded harder than the calculator assumed.
- You have HECS/HELP, which reduces net income.
- Dependants raise the expense benchmark.
- Your statements reveal commitments you forgot to enter — subscriptions and buy now, pay later balances included.
A good habit: re-run the calculator with pessimistic inputs (expenses a little higher, bonus income excluded) and treat the range between the two results as your realistic zone.

Borrowing power vs sensible budget
The maximum a lender will approve and the amount you should borrow are different questions. The assessment buffer gives you some protection against rate rises, but it does not know your plans — a career change, a child, a renovation, single-income years. Many borrowers deliberately set their budget below their maximum so their repayments stay comfortable, not merely serviceable. A useful sanity check is the repayment as a share of your take-home pay: if the buffered repayment would leave you with no room to save, absorb a bill shock or enjoy your life, the fact that it technically services is cold comfort. Use our [repayment calculator](/calculators/repayment) to translate any loan amount into weekly, fortnightly or monthly repayments and stress-test them against your actual life.
From estimate to real assessment: the next steps
When you are ready to firm the number up, the path looks like this:
- Gather documents — payslips, statements, ID; the full checklist is in [documents needed for a home loan](/articles/credit-and-approval/documents-needed-home-loan).
- Get your credit file position clear — know what enquiries and accounts a lender will see.
- Match to a lender — this is where a broker earns their keep: picking the lender whose policy treats your income mix, debts and deposit best, rather than lodging blind.
- Seek pre-approval — a conditional decision from a real lender, typically valid for around three months, that lets you make offers with confidence.
- Keep your position stable — between pre-approval and purchase, avoid new debts, job changes or large unexplained transactions, since lenders can reassess before final approval.

Common mistakes with calculator results
The two classic errors run in opposite directions. The first is treating the number as gospel and signing a contract at your theoretical maximum before any lender has verified anything — risky, especially at auction where there is no finance clause. The second is giving up because one calculator produced a low number, when a different lender's policy might treat your situation far better. Both errors have the same fix: verify the estimate against real lender policy before you act on it. Our guide to [application mistakes](/articles/credit-and-approval/loan-application-mistakes) covers the broader traps.

Frequently asked questions
Is a borrowing power calculator result accurate?
It is a reasonable estimate if your inputs are honest and complete, but it runs on generalised policy and unverified numbers. The real figure depends on lender-specific rules about income shading, expenses and debts, and can land above or below the calculator's answer.
Why did two calculators give me different borrowing power numbers?
Each calculator embeds different assumptions — the buffer rate, expense benchmarks, how bonus or rental income is treated, and how credit cards are assessed. Different assumptions, different answers. The spread between them is itself useful information about how policy-sensitive your situation is.
Should I borrow my maximum?
Not necessarily. The maximum is what a lender judges you can service with a buffer — it is not a recommendation. Many borrowers set their budget below the maximum so repayments stay comfortable through rate rises and life changes.
How do I turn an estimate into pre-approval?
Gather your documents, get matched to a lender whose policy suits your profile, and lodge a pre-approval application. The lender verifies your income, expenses and credit file and issues a conditional approval, typically valid for around three months.
Can I make an offer on a property based on a calculator result alone?
You can, but it is risky — particularly at auction, where contracts are usually unconditional. A calculator result is unverified. Pre-approval, while still conditional, is a far stronger basis for making offers.
