Lenders don't test you at your actual rate — they add a mandatory 3% serviceability buffer and check you could still afford repayments at the higher rate above. Your borrowing power is calculated on that buffered rate.

This is an indicative estimate only, not a loan offer, quote, pre-approval or a statement that credit is available. It is a general guide based on a simplified version of the serviceability method lenders use. Your actual borrowing capacity depends on your full financial position, the specific lender's policy and credit assessment.

The method behind the number

How lenders actually work out your borrowing power

It is not simply a multiple of your salary. Australian lenders are required to test whether you could still afford the loan if rates rose — this calculator mirrors that logic in plain English.

1

Your surplus, not your salary

Lenders start with your net income, then subtract living expenses, existing loan repayments and a portion of your credit card limits. What is left — your monthly surplus — is what can service a new loan.

2

The 3% APRA buffer

Regulators require lenders to assess you at your interest rate plus a 3% serviceability buffer. So a loan advertised near 6% is tested closer to 9%. This buffer stayed at 3% into 2026 and is the single biggest constraint on capacity.

3

Converted to a loan size

Your surplus is worked back into the largest loan whose repayments — at that buffered rate over your chosen term — your surplus can cover. Policies differ by lender, which is where a broker earns their keep.

Move the needle

What changes how much you can borrow

Small changes to these levers can move your capacity by tens of thousands. A broker can model each one against real lender policy.

Credit card limits

Lenders count a percentage of your total limit as a monthly commitment — whether or not you owe anything. Reducing or closing unused cards can lift capacity quickly.

Existing debts

Personal loans, car finance and BNPL all reduce your surplus. Consolidating or clearing a small debt before applying can free up meaningful borrowing room.

Income type & consistency

Base salary, overtime, bonuses, rental and self-employed income are each treated differently — and lenders vary widely. The right lender for your income mix matters.

Loan term & structure

A longer term or interest-only period changes the assessed repayment. Structure has to suit your goals, not just maximise the headline number — we help you weigh both.

Common questions

Borrowing power, explained

It gives an indicative estimate, not a precise figure. It uses a simplified version of the serviceability method — net income minus living costs and commitments, serviced at your rate plus the 3% APRA buffer over your chosen term. Real lender assessments use detailed income verification, their own expense benchmarks (HEM) and individual credit policy, so your actual capacity can be higher or lower. Treat the number as a conversation starter, then get a proper assessment.

APRA requires lenders to check that you could still afford repayments if interest rates rose. They add a buffer — currently 3 percentage points — to your actual rate and assess your repayments at that higher "assessment rate". A loan advertised around 6% is therefore stress-tested closer to 9%. This buffer remained at 3% into 2026 and is usually the single biggest reason your borrowing power is lower than a simple income multiple would suggest.

Lenders treat your total credit card limit as a potential debt, whether or not you carry a balance. A common approach is to count around 3.8% of the limit as a notional monthly repayment. So a $20,000 combined limit can knock a meaningful amount off your capacity. Reducing limits or closing cards you do not use is one of the fastest ways to lift your borrowing power before applying.

Yes — switch the purpose toggle to "Investor" and add your expected weekly rent. Lenders count a portion of rental income (they "shade" it, often to around 80%, to allow for vacancy and costs) and assess investment loans under their own policies. Negative gearing, existing property debt and interest-only structures all affect the outcome, so investor capacity in particular benefits from a broker running the numbers across multiple lenders.

You can, but be cautious. Self-employed income is assessed very differently — lenders look at business financials, add-backs, consistency and structure, and low-doc options exist for those without two years of returns. The estimate here assumes straightforward income, so if you run a business it is best treated as a rough guide only. This is exactly where a broker who works with self-employed clients adds the most value.

No. This tool runs entirely in your browser, collects no personal data to produce the estimate and does not perform any credit check or enquiry. Only when you choose to submit an enquiry to us do we receive your details — and even a formal borrowing assessment with a broker does not put a hard enquiry on your file until you actually apply for a specific loan.

Often, yes — not by bending the rules, but by matching you to the lender whose policy suits your income type, debts and goals. Lenders vary widely in how they assess overtime, bonuses, rental income, HECS debt and expenses. A broker compares your situation across a panel of 50+ lenders to find the strongest genuine outcome, and structures the loan so it still fits your budget.
