This calculator provides estimates based on standard lending criteria. Lenders use different affordability models and will consider employment history, credit score, and down payment. Always consult a mortgage adviser for a formal assessment. Figures are illustrative only.
How Much Mortgage Can You Qualify For?
Lenders determine your maximum borrowing capacity using an income multiple (typically 4.5x your annual salary, sometimes up to 5x or 5.5x for high earners) and a strict affordability stress test checking your monthly outgoings.
A mortgage affordability calculator estimates the ceiling of what a bank will lend you. Crucially, just because you qualify for a massive mortgage does not mean you should take it. You must ensure you can comfortably afford the monthly repayments without severely compromising your lifestyle.
Frequently Asked Questions
Is there a 5 times salary mortgage calculator?
Yes, our calculator allows you to adjust the income multiplier up to 5x or even 5.5x. However, in the UK, the Bank of England heavily restricts the number of mortgages lenders can offer at multiples of 4.5 or higher. To qualify for a 5x multiple, you usually need a pristine credit score and a high combined household income.
Do personal loans affect my mortgage approval?
Yes, significantly. Lenders legally must factor in your exact monthly debt obligations (car finance, personal loans, credit card balances). These fixed outgoings drastically reduce your monthly disposable income, which lowers the maximum amount you can borrow.
