FAQs
What is the 28/36 rule?
It is a common lending guideline: housing costs should stay within 28% of gross monthly income, and total debt repayments within 36%. This calculator applies both limits and uses the lower result.
Does this include taxes and insurance?
No. It estimates the mortgage payment for the loan itself. Remember to budget separately for council tax, buildings insurance and maintenance.
Is this a mortgage offer?
No. This is a planning estimate only. Lenders apply their own affordability checks, including your credit history, spending and employment type.
How can I afford a higher amount?
A larger deposit, a lower interest rate, a longer term or higher income all raise the affordable amount, while paying down existing debts helps too.
