Your planning tools
Choose a calculator.
Mortgage repayment calculator
What could your mortgage cost each month?
Compare estimated capital-and-interest repayments with interest-only payments. Adjust the property price, deposit, interest rate and term to suit.
Mortgage overpayment calculator
See how paying a little more could change the journey.
This illustrates the potential time and interest saved when a regular monthly overpayment is made and the interest rate stays unchanged.
Residential property tax calculator
One calculator for all three UK property-tax systems.
Select where the property is located and your buying position. The calculator applies the current SDLT, LTT or LBTT bands.
England and Northern Ireland use Stamp Duty Land Tax (SDLT).
Important
Useful estimates, not advice or a mortgage offer.
Mortgage results exclude product fees, legal costs and changes in interest rate. Property-tax rules can depend on ownership, residency, replacement of a main home, linked transactions, companies, trusts, leases and available reliefs. Confirm the final amount with your solicitor or tax adviser.
Property-tax rates checked 29 August 2026 against HMRC, Welsh Government and Revenue Scotland.
