They give you a genuine estimate based on the numbers you enter and standard industry assumptions, but they're not a substitute for a full assessment. Every lender weighs income, expenses, and credit history slightly differently, so your actual borrowing power, repayments, or approval outcome may vary. Use these as a starting point, then talk to a broker for a number you can rely on.
No. These calculators don't run a credit check and don't contact any lender, so there's no impact on your credit score at all. You can adjust the numbers and recalculate as many times as you like.
No. Pre-approval (also called conditional approval) comes from an actual lender after they've reviewed your documents and run their own assessment. The Borrowing Power Calculator gives you a general estimate to help you understand your range before you get to that stage.
Every lender applies its own serviceability rules, some are stricter on living expenses, others treat overtime or bonus income differently, and some apply a bigger buffer to interest rate rises. That's exactly why comparing across our panel of 60+ lenders matters, one lender's no is often another lender's yes.
Either is fine. Nothing you enter is saved, stored, or sent anywhere, these calculators run entirely in your browser. Feel free to try a few different scenarios before you talk to us.
Mostly no. The Repayment and Refinance calculators show principal and interest only, not application, valuation, or discharge fees. The Stamp Duty calculator shows duty only, not conveyancing or other settlement costs. We can walk you through the full cost picture once you're ready to move forward.
