Free UK mortgage calculators and tools
Estimate how much you may be able to borrow, what your monthly repayments could be, how Stamp Duty may apply, and how remortgaging or overpaying could affect your mortgage.
The calculators on this page are guidance tools only. They are not regulated mortgage advice, tax advice, legal advice, financial advice, a personalised mortgage illustration or a mortgage offer. Actual lending decisions will depend on the lender's assessment of your income, outgoings, credit history, deposit, loan-to-value, property type and wider circumstances.
Your home may be repossessed if you do not keep up repayments on your mortgage. Think carefully before securing other debts against your home. Not all buy-to-let mortgages are regulated by the Financial Conduct Authority.
