Mortgage repayment calculator
Purchase price, deposit, rate and term — and the monthly figure.
What it is for
Putting a repayment figure on a property listing or a broker's page, where that number is the thing somebody came to find out. It opens on a typical purchase and recalculates as the numbers are changed, so a visitor sees a plausible answer before touching anything.
When to show it
Part-way down a listing rather than on arrival. Somebody who has scrolled past the photographs has told you which property they are pricing, which a timer cannot. This preset uses a scroll trigger for exactly that reason. The opening numbers matter more here than in most widgets, too: plenty of people never touch a field, so whatever it starts on is the figure they take away.
When not to use one
Do not present it as advice. It is an illustration built from four numbers, and it knows nothing about fees, insurance, a rate that changes after two years, or the person using it. Say that beside it. In the UK, giving regulated mortgage advice is a permission you either hold or you do not, and putting a calculator on a page does not change which.
Questions
- Can I change how the figure is worked out?
- Yes. The formulas are yours — the preset is a starting point, and every number feeding it is a field you can rename, remove or add to.
- Can I include fees or insurance?
- Yes, by adding the field and putting it in the formula. Nothing about the preset is fixed once it is in your editor.
- Is anything somebody types sent to you?
- No. It is worked out in their browser and stays there unless the widget also asks them to send it, which this one does not.
- Is this financial advice?
- No, and it should not be presented as any. It is an illustration of one arithmetic result, and what you write around it is your responsibility.
