An estimate for guidance, not an offer or a decision. What a lender will actually advance depends on your income, your commitments and the property.
What this tells you
The monthly payment on a given loan at a given rate, and the total interest across the term. It is the same arithmetic every lender uses, so the number is real.
What it does not tell you
Whether a lender will actually lend you that much. That depends on your income, your commitments, your credit history and the property itself, and it varies between lenders far more than most people expect.
The rate is your assumption, not our offer
We are not permitted to publish rates. Put in a figure you have been quoted or seen advertised. Then move it by half a percent and watch what happens, because that sensitivity is the thing worth understanding.
Interest only looks cheaper because it is not repaying anything
The monthly cost is lower because the balance never falls. You still owe the whole amount at the end of the term, and a lender will want to see a credible plan for clearing it before they agree to it.
This is a calculator, not advice
Everything above is arithmetic on the figures you typed in. It is not a recommendation, not a decision in principle, and not an offer. What it is good for is telling you whether you are in roughly the right area before you spend an afternoon on property listings.
A number is not an answer.
These tools give you the shape of it. What they cannot do is tell you which lender will say yes, and on what terms, which is the part we actually do. The first conversation costs nothing and commits you to nothing.
