Run the Numbers the Way a Bank Would Run Them
Before you commit to a loan, it helps to see what your lender sees. These calculators use the same repayment, serviceability and break-even logic our partners applied inside bank credit teams — so the figure you plan around is one that holds up under assessment.

What Your Bank Knows About These Numbers That You Don’t
Each tool above answers one question cleanly: what a loan costs, what you may be able to service, whether a switch pays, and what paying extra does to the life of the loan. The maths is exact. The outcome is only ever as good as the assumptions behind it — which is why every figure here is an estimate, not an offer, and why the number a lender lands on can differ once your position is assessed against their current policy.
Use these to decide whether a loan is worth pursuing. Use a partner to find out whether it is achievable, and on what terms.
