This calculator looks beyond what a lender might offer. It estimates your mortgage payment, lifestyle pressure, moving costs, emergency risk and monthly leftover so you can see whether the house fits your real life.
Enter the house price, your deposit and your monthly income. Then choose a lifestyle level to see whether this house would feel comfortable, stretched or risky.
Choose the lifestyle that feels closest to your household. This covers food, transport, clothes, subscriptions, socialising, children’s extras, pets, holidays and day-to-day spending.
A mortgage lender mainly wants to know whether you are likely to make the mortgage payment. That is important, but it is not the full picture. Real affordability also includes your bills, debts, food, cars, children, pets, repairs, savings, holidays and how much cash is left after the move.
Usually focuses on income, debts, credit profile and stress-tested mortgage payments.
Looks at whether you can still live normally after the mortgage, bills and everyday spending.
Checks whether getting the keys wipes out your cash buffer before repairs and setup costs begin.
The first few months after moving can be expensive. These smaller costs often arrive together, which is why this calculator includes a setup and emergency layer.
You have decent monthly breathing room, your buffer survives the move and the stress test does not immediately push you into trouble.
You may be able to afford the house, but rate rises, repairs or higher bills could quickly tighten things.
The house may technically be possible, but it could control your lifestyle and leave you vulnerable to debt.
No. A mortgage affordability calculator usually estimates how much a lender may allow you to borrow. This calculator focuses on whether the house feels affordable after mortgage payments, bills, debts, lifestyle spending, moving costs and repairs.
Use net monthly household income. That means the money actually arriving in your bank after tax, National Insurance, pension deductions and other payroll deductions.
There is no perfect number, but a stronger result usually means you still have a meaningful percentage of your take-home pay left after mortgage, bills, debts, maintenance and lifestyle spending.
Because a house can be affordable on paper but difficult in real life. Food, cars, children, pets, clothes, socialising and holidays all affect whether a mortgage feels comfortable.
Buying a house is not only about the monthly mortgage. Legal fees, surveys, removals, stamp duty, furniture, curtains, repairs and setup costs can reduce your cash buffer before you have settled in.
The boiler test checks whether you could handle a large repair shortly after moving without relying on debt. If this fails, the calculator will not give a Comfortable verdict.
Yes. A lender may approve a mortgage based on their rules, but that does not automatically mean the house will feel comfortable once normal life, repairs, savings and moving costs are included.
No. This calculator is a planning tool only. Mortgage eligibility, lending rules, interest rates and personal circumstances should be checked with a qualified mortgage adviser or lender.
