How to Read Your Result

Four things worth understanding before you talk to a lender.

The payment is only part of it Property taxes, insurance, and maintenance sit on top of the figure this tool shows. Ask your lender what their quoted payment includes.
Early payments are mostly interest Open the repayment schedule: in the first years, most of each payment covers interest. That flips slowly as the balance falls.
The deposit moves the rate Below 20% down, many lenders price the loan higher or require mortgage insurance. The tool shows your loan-to-value so you can see where you sit.
Small extra payments compound Set an extra monthly repayment under "Adjust the details" — the second line on the chart shows how much sooner the loan clears.

What This Tool Does and Doesn't Do

The maths is standard amortization — the same formula a lender uses — and it runs entirely in your browser. Nothing you type is sent anywhere unless you press "Explain my numbers", and even then only the figures go, never your name or contact details.

What it can't do is quote you. Rates, fees, insurance requirements, and tax treatment differ by country, by lender, and by your own profile. Treat the result as a well-informed estimate that tells you which questions to ask.

Important: This is educational information, not financial advice. Confirm the figures with a qualified adviser or your lender before you commit to anything.
