Affordability
Gross salary vs mortgage payment: a sanity check
Before you speak to a lender, it helps to know whether the housing payment you are modelling looks plausible against your take-home pay. That means the mortgage repayment plus running costs — council tax, maintenance, insurance — not the repayment alone.
Start with gross salary to estimate monthly net pay after tax and National Insurance. Then add the home scenario — repayment, council tax, maintenance, and insurance.
If the combined housing figure is a large share of net income, you have less buffer for life costs, savings, and rate rises at renewal. That is a prompt to stress-test a higher rate or a larger deposit — not a yes or no on whether a lender would approve you.
Income and other debt in one view
You can also enter monthly net income and other debt payments alongside the housing scenario for a structured view of how much headroom is left. A lender’s affordability test will use its own rules and stress rates — this is for your own planning.
