Your Results
This mortgage calculator is based on the typical UK lending criteria of 4–4.5× your annual salary. Your results will show a borrowing range:
- - Green = the more realistic amount lenders are likely to approved
- - Red = the upper limit most lenders would consider in ideal circumstances
Important: This Is Only an Estimate
Mortgage lenders also assess your monthly outgoings, credit score, and employment status before confirming how much they’ll lend. Use this tool as a guide, but always speak to a mortgage advisor or lender for personalised, accurate figures based on your full financial situation
Mortgage Affordability: What Lenders Really Look At
Most UK mortgage lenders typically allow you to borrow up to around 4.5× your annual income, which is why the top end of the bar chart sits in the red zone. This loan‑to‑income ratio is one of the key factors used to calculate how much you can borrow.
If you have no significant debts and a strong credit score, you're usually well placed to secure a mortgage within the green affordability range.
Key Factors That Affect Your Mortgage Borrowing Power
When assessing your application, lenders will review your monthly financial commitments, including:
- Personal loans and credit agreements
- Credit card balances and repayments
- Child maintenance payments
- School fees
- Regular bills, subscriptions, and household expenses
These outgoings help lenders determine your true affordability and the maximum mortgage amount they're willing to offer.
Boost Your Chances Before You Apply
If you're planning to apply for a mortgage soon, it's a smart move to start budgeting as if you're already making mortgage repayments. Lenders often check recent bank statements to confirm you can comfortably manage the monthly payments.
If you haven't created a budget yet, now is the ideal time to put one in place—it can make a noticeable difference to your mortgage approval prospects.
