Your starting point
Compare what you would pay across different assumptions. A calculator helps you explore a scenario; only a lender can assess an application and offer credit.
The mortgage tool models equal monthly repayments using the capital, annual nominal rate and term you enter. Use the steps below to organise a decision, not to infer an official approval, a guaranteed price or a universal deadline.
Work through the decision
Understand the formula
Monthly rate equals annual rate divided by twelve; the standard annuity formula gives the payment.
Know the exclusions
The result excludes insurance, fees, taxes and future rate changes unless entered as separate scenarios.
Check the offer
Compare the model with the lender's repayment schedule before using it for a real commitment.
Adapt this to your circumstances
Keep citizenship, current residence, household needs and the location of the home separate in your notes. Ask the responsible authority, institution or qualified professional to confirm any requirement that affects your situation. A checklist used by another household may not apply to yours.
