UK Mortgage Affordability Estimator
This mortgage affordability estimator is designed to give you a fast indication of how much you may be able to borrow and what sort of property budget that could support. It combines an income multiple view with a stress-tested monthly payment view so you can see which limit is more restrictive.
What this affordability tool includes
- Main income, second applicant income and other provable income
- Deposit and optional target property price
- Monthly committed costs
- Mortgage term, initial rate and stress rate
- Income multiple scenarios
- Estimated borrowing and property budget
- Optional target-property check with estimated LTV and payments
How this mortgage affordability estimate works
The tool first estimates a borrowing limit using your chosen income multiple. It then estimates a second borrowing limit based on an affordable monthly payment capacity, using your selected housing ratio and stress rate. The lower of the two values is used as the indicative borrowing figure.
Why lenders may differ
Real mortgage affordability checks can vary by lender. They may use different income rules, stress rates, treatment of overtime or bonus income, age limits, credit commitments and household spending assumptions. This tool is designed as a planning estimate rather than a lender decision.
Important note
This calculator provides general estimates only. It does not perform a credit check and does not guarantee mortgage approval.
