Borrowing Power Calculator
Borrowing Power Calculator See Your Numbers Before You Apply
This borrowing power calculator estimates how much you could borrow for a home loan based on your income, expenses, and existing commitments. Enter your income, whether it’s joint, your dependents, your living expenses, and any car loans, other payments, or credit card limits, and it returns an estimated borrowing amount along with your monthly, fortnightly, and weekly repayment.
The figure gives you a starting point before you speak with a lender or broker. Output is an estimate based on your inputs and a standard interest rate and loan term, not a loan approval.
How This Calculator Works Out Your Number
The borrowing power calculator takes your income sources first, salary, a second income if it’s a joint application, and any other net income, then subtracts your outgoings. Living expenses, car loan payments, and other payments all reduce what’s left over for a loan repayment. Your credit card limits are factored in too, since lenders count what you could draw on, not just what you currently owe.
From there, the interest rate and loan term you set determine how much of that leftover amount could support a mortgage. A longer term or lower rate generally increases the number, while a shorter term or higher rate brings it down. The calculator also shows a loan balance chart so you can see how the balance and total payments track against each other over the life of the loan.
Why Dependents and Credit Card Limits Move the Number More Than You’d Expect
Two inputs on this calculator tend to surprise people the most. Dependents reduce your assessed borrowing power because lenders apply a higher living expense benchmark for each child or dependent in the household, even if your actual spending is lower. Going from zero to two dependents can shift the result by tens of thousands of dollars.
Credit card limits work the same way. A lender assumes you could max out every card you hold, so a $20,000 limit reduces your borrowing power by a meaningful amount even if you pay your balance off in full every month. Reducing limits or closing unused cards before applying is one of the more direct ways to lift the number this calculator returns.
How ADA Financial Services Helps
A borrowing power calculator gives you an estimate on standard settings. A broker tells you what different lenders would actually offer, since assessment rules vary more than most borrowers expect on things like overtime, bonuses, and existing debt.
ADA Financial Services reviews your full position, including income, dependents, and any consumer debt, and compares lenders on how they treat your specific circumstances. We identify which lenders assess your situation most favourably before you commit to an application. Our fee is paid by the lender at settlement in most standard cases, disclosed in writing before any application proceeds. We’re based on the Sunshine Coast and work with borrowers across Northern Australia.

FAQs
Why does the calculator ask about my credit card limits, not my balance?
Lenders assess borrowing capacity assuming you could draw the full limit on every card, regardless of your current balance. Reducing limits before applying can materially increase your result.
Does having dependents really reduce how much I can borrow?
Yes. Lenders apply a higher living expense benchmark for each dependent, which lowers the surplus available for loan repayments, even if your actual household spending is lower.
Why is my borrowing power estimate different from what my bank offered?
Every lender applies its own income shading, expense benchmarks, and buffer rate, so the same financial position can return a different number at each lender. This calculator gives a general estimate, not a specific lender’s assessment.
Does joint income increase borrowing power by the full second salary?
Not necessarily. Lenders combine both incomes but also assess combined expenses and dependents together, so the increase depends on your full household position rather than the second salary alone.
What This Loan Repayment Calculator Shows
This loan repayment calculator estimates what you will pay each month on a home loan, how much of that payment goes to interest versus principal, and the total interest charged across the full term. You enter your loan amount, interest rate, term, and repayment frequency. The output gives you a clean repayment figure to plan around and a total cost number that most borrowers underestimate.
The estimate is based on the inputs you provide and assumes a standard principal and interest loan with a constant interest rate. Real loans vary as rates move and fees apply. Treat the output as a planning figure, not a loan offer.
